2: Product Information

DescriptionThe King Cobra Mud Conditioner consists of Hydrocyclones mounted over a King Cobra Shaker. Several different configurations are available using one or more different types of Hydrocyclones. Valves in the trough send the Hydrocyclone underflow to either the backtank of the King Cobra Shaker or a bypass line.

Refer to the King Cobra Shaker and Hydrocyclone manuals for details of their operation.

3: Installation

FoundationThe King Cobra Mud Conditioner requires a sturdy level foundation able to support the weight of the assembly. Adequte room around the unit is required for maintenance.

LocationThe unit should be located with regard to proper disposal of the solids from the King Cobra shaker and convenient feed and discharge lines for the Hydrocyclone headers.

4: Operation

ValvingThe only operations specific to the mud conditioner are whether the Hydrocyclone underflow is directed to the King Cobra Shaker or to a bypass line for other processing. When one of the valves is closed, the other valve should be open.

Closing both valves while the Hydrocyclones are operating will cause the trough to overflow.

Product Information

IntroductionThe role of a King Cobra™ separatorThe standard NOV Brandt King Cobra separator is a fine screen shaker with a motor/starter option for either linear motion or tuned elliptical motion. The separator is almost always located at the flow line unless it is preceded by a “scalping” or gumbo separator. The King Cobra removes a large percentage of drill cuttings before the mud is circulated through the surface mud system, leading to improved performance of downstream solid control equipment.

The King Cobra separator is designed to do two primary jobs: separate drilled solids from the mud; transport the solids rapidly and efficiently off the screens.

How the King Cobra worksThe three features key to the operation of the King Cobra are the basket and angle adjustment system, the vibrator system, and the screen locking system. These systems work with the uniquely designed separator basket to give the highest fluid throughput and driest solids in a compact and reliable separator.

King Cobra basket and pivot systemThe basket’s patented screen configuration is a major advance over previously available separators. During normal operation, with the basket in the neutral position, the first screen is evenly flooded with 1 to 2 in (25 to 51 mm) of mud. The pool of mud creates an even hydrostatic head on the screen surface that increases the amount of mud that can pass through the first three screens. (See Figure 2-1.)

In traditional shakers, with all screens in the same plane, the operator must raise the basket to create a liquid pool. The resulting pool is wedge shaped and can cause a slow-moving solids bed to form. (See Figure 2-2.) The material in the slow-moving solids bed is very slow to convey and is ground into fine solids, which negatively affects the mud system. Screen life is also jeopardized due to slow-moving solids bed formation. Because the first screen of the King Cobra is flooded more evenly and shallowly, a slow-moving solids bed does not form, thus increasing screen life and optimizing shaker performance.

Figure 2-2. Typical linear shaker angled uphillshowing a stationary solids bed

The design of the King Cobra basket also includes a drying screen. During normal operation the liquid pool extends to the end of the third screen, and the fourth screen is used to remove all excess liquid from the screened particles (dry the cuttings). During flow surges or changes in flow conditions, liquid can run off the end of the third screen and onto the fourth screen. Fluid on the fourth screen flows back to the baffle plate and builds up a second pool, preventing the loss of any whole mud off the end of the shaker. (See Figure 2-3.)

The King Cobra has a manually operated basket angle adjustment system. The angle adjustment system allows the basket to be tilted upward by as much as 3° and downward by as much as 5°. During unusually heavy flow conditions the basket can be pivoted uphill to increase the depth of the pool. This deeper pool allows the shaker to handle the unusual flow conditions without a loss of whole mud off the end of the shaker.

Sticky clays and gumbo often do not convey uphill and may not convey horizontally with a linear motion shaker. When sticky clays or gumbo are encountered, the basket can be tilted downward to make sure that the material conveys. The operator can adjust the basket angle while the unit is running by using the hand wheels located on each side of the basket. An angle adjustment plate and safety pendant near the back of the basket show the basket angle and take the load off the jacking system during normal operating conditions.

.

If your King Cobra separator is equipped with the tuned elliptical motion option, you may find that switching from linear motion to tuned elliptical motion results in improved conveyance of sticky clays and gumbo.

Vibrator systemThe vibrator system includes the two canister type vibrator motors, a motor mounting motion tube, and a plate. Each vibrator motor contains eccentric weights that generate a circular shaking force when rotated. During operation the two motors rotate in opposite directions, creating either a net linear or a net elliptical shaking force on the basket. This shaking force is directed through the center of mass of the basket, resulting in an equal motion along the entire length of the screening surface. The motion conveys the solids along the screen, even uphill, and off the discharge end of the shaker. The basket motion has been carefully designed to give the unit optimum performance over a wide range of drilling conditions.

The angle of the basket’s vibratory motion, relative to a line perpendicular to the screen surface, is called the angle of attack (conveyance angle). The angle of the basket’s motion relative to a line parallel to the screen surface is called the conductance angle. The King Cobra uses a 40° conveyance angle and a 50° conductance angle. See Figure 2-4 for a diagram of these angles.

Installation

InspectionPrior to setting up and operating a new King Cobra separator, inspect the goods as received from the shipping company. A claim for damage or loss should be reported immediately to the carrier and to NOV Brandt. Eight screen wedges and 24 screen crown rubbers ship in a separate box located in the backtank of the unit. Check the bill of lading for any separately shipped items, including manuals and CDs.

Once it is confirmed the order has been received complete in undamaged condition, installation of the King Cobra may begin.

Lifting and Handling ProcedureShale Shaker AssemblyThe King Cobra shaker can be lifted with the use of a properly rated forklift, or by utilizing the four (4) designated lift points on the skid. These lift points can be fitted with properly rated lifting shackles and slings in order to safely handle the unit.

Lifting equipment needs to be rated to handle the dead weight of the shaker, 4300lbs (1950kg), plus a safety factor. Always utilize certified lifting equipment and follow manufacturers' recommended practices.

Figure 3-1. Lifting points

Never attempt to lift a King Cobra shaker by attaching shackles or slings to anything other than the designated lift points.

3: Installation

Basket AssemblyThe King Cobra basket assembly, consisting of the basket and drive motors, can be lifted by either wrapping soft slings around the motor tube, below the motor base plate; or by connecting properly rated lifting eyebolts and slings to the four (4) basket spring mounts. The former method is only recommended for short, close proximity lifts in which a guide line is used to continuously control the load; for example when installing a basket into a skid or support structure. Always utilize the latter four-point method for major lifting operations.

Unit preparationRead these instructions carefully and completely before you begin. Failure to do so may result in personal injury or damage to the unit.

1. Remove the four shipping bolts and spacers (see Figure 3-2) and store in a safe place for reuse.

Figure 3-4. King Cobra wiring diagram for tuned elliptical motion option

4. Check for proper voltage (labeled on the starter enclosure) and make sure all connections are tight. The motor junction boxes on the motors are pre-wired for the correct voltage at the factory.

5. Remove the weight covers from one side of the vibrator motors.

6. Turn on power supply to unit.

7. Check the motor rotation direction of the standard King Cobra separator as follows (skip tostep 8 if your King Cobra separator has the tuned elliptical motion option):

a. Bump start the motors to check motor rotation. To bump start the motors, push the start button on the starter box, and then quickly push the stop button.

b. Motors must rotate in opposite directions away from each other relative to the top of the motors. Follow the arrows on the motors. If the motors turn in the same direction, switch any two wires on one of the motors in the motor starter box to reverse its direction.

8. Check the motor rotation direction of the King Cobra separator with the tuned elliptical motion option as follows:

Wires in the motor junction box must not be allowed to touch the inside of the junction box. Use the foam cushions supplied with the motor to protect the wires.

Operation with both motors turning in the same direction results in very poor shaker performance.

3: Installation

a. Turn the motion selector switch to Elliptical.

b. Bump start the motors by pushing the start button on the starter box and quickly pushing the stop button. Make sure both weights follow the rotation arrows and the top motor is rotating toward the front (discharge) end of the shaker. If so, go to step 9.

c. If both motors are rotating incorrectly, switch the positions of any two of the wires L1, L2 and L3. Bump start the motors again to confirm correct rotation direction and go to Step 9.

d. If one motor is rotating correctly and the other motor is rotating incorrectly, switch the positions of any two of the wires T1, T2 or T3 at the overload relay for the motor with the incorrect rotation. Bump start the motors again to confirm correct rotation direction.

9. Replace the motor weight covers. Bolt down the motor junction box covers and the starter box cover.

10. Start the unit and check for proper vibration.

There should not be any side-to-side motion of the basket. Check side-to-side motion by placing a thumb and forefinger on either side of the upper basket rail. The motion of the basket should cause the rail to slip between the thumb and fingers without touching the fingers.

If side-to-side motion does occur:

1. Check that the shaker is level.

2. Check that the counter weights are set identically.

InstallationThe following information provides the proper installation procedures for efficient and safe operation. Please follow the recommendations closely. As always, adequate working space, walkways, and handrails should be considered.

Location and supportThe King Cobra is shipped assembled on a box type skid with an integral sump and backtank. Although most of the basket vibration will not be transmitted through the coil spring and into the skid, it is recommended to skip weld or bolt the skid to the support structure on which it is placed. The support structure must be designed to support the shaker’s dead weight of 4300 lb. (1950 kg), plus a fluid load of 3000 lb. (1361 kg) for a total of 7300 lb. (3311 kg) per unit.

The operator needs access to both sides of the machine to change the screens. Allow at least 24 in (0.6 m) of free space around the machine. Catwalks or walkways around the entire machine are very important, because they increase the chances of proper maintenance.

Throughout this manual, the “back” of the King Cobra is the feed tank end, and the “front” is the end where the dried solids fall off. Left and right are determined by looking at the machine from the front.

Ensure the skid is grounded before welding. Failure to do so can result in electrical system damage.

Surfaces of the equipment are slippery. Use caution when working on or around to avoid falling.

Page 56: Cobra Manual

Document number M12444Revision 13Page 20 of 60

3: Installation

Some other guidelines for locating and installing the shaker include:

1. The unit(s) must be level in both directions to ensure even fluid distribution.

2. Do not weld or attach discharge troughs to the vibrating deck.

3. Do not install the solids slide above the bottom of the front shaker skid cutout.

Flow line connectionThe flow line should connect near the bottom and center of the backtank. This minimizes settling of solids. “Over the top” connection of the flow line to the backtank is discouraged. If necessary, the pipe must be inserted at least two-thirds to the bottom of the backtank to prevent solids buildup. Solids buildup in the backtank results in an undesired reduction in the volume of the backtank and blockage of the dump valve. The drop or slope of the flow line should be a minimum of 1:12, or 1 ft. (0.3 m) of drop for each 12 ft. (3.7 m) of the flow line.

The preferred hookup between multiple shakers is to use “Y” or “T” connections between the shakers. Use valves to regulate flow to each shaker. This way, one shaker can still function while repairing or changing a screen on the other shaker. For controlling flow, knife gate valves are preferred over butterfly valves.

Screen installationScreen installation requires minimal time or effort. However, if you do not follow these basic steps, the result may be poor screen life and solids bypassing into the active system.

1. If mud is circulating, open the backtank bypass valve or divert mud to other shaker.

2. Wash down the screens while the shaker is running.

3. Shut down shaker.

4. Remove the screen wedge on each side of the basket for the screen being removed. Each pre-tensioned screen on the King Cobra may be removed individually without removing the others.

5. Place screen wedges outside the basket in a safe place so they cannot fall into the sump of the separator or into the mud tanks.

6. Remove the screen panel.

7. Replace worn or missing screen seals, screen supports, and crown rubbers. Screen seals must be replaced in pairs and crown rubbers in sets.

8. Carefully lay in the new pre-tensioned screen panel.

9. Install screen wedges in designated slots on each side of the basket.

Minimum access distance recommended is sufficient for maintenance and operation of the unit. User should check local regulations to ensure that additional space is not required.

Wash down the screen support area prior to installing a new screen.

Do not operate the machine without all screen seals and crown rubbers in place. See section titled "Replacing seal strips and crown rubbers" on page 33.

10. Check to see that the screen is straight across the basket and is engaging the retainer pins (current configuration) or is behind the retainer plate (obsolete configuration).

11. Tighten screen wedges using a hammer or pry bar.

12. Check that screen wedges are tightly secured.

13. See Figure 3-5 for the correct screen installation.

Figure 3-5. Correct installation of screens

Storage Store the King Cobra in a cool, dry place with the ability to test the unit for three hours once a month.

During storageIf the King Cobra is to be stored after receipt instead of being immediately installed and operated, the following steps should be taken to ensure the unit does not degrade during storage.

When stored in a cool, dry location with adequate power:

1. Keep shipping bolts on the shaker at all times while in storage, if movement is possible. The only exception is when the shaker is tested once a month. After the test or before shipment, replace the shipping bolts. (See Figure 3-2 on page 16.)

2. Test the operation of the shaker once a month. This requires connecting power to the shaker, removing the shipping bolts, and running the shaker for three hours.

If your screens do not have holes to accommodate the retainer pins, contact your NOV Brandt representative for assistance in retrofitting your screens. To locate the NOV Brandt office nearest you, see Chapter 8, titled "Worldwide Locations".

3. Open the starter box cover and spray the components with a water displacing solvent (for example, WD-40®). Allow the solvent to dry, and then close the starter cover tightly. Keep all other connections intact. Use desiccant bags in starter and junction box in order to minimize moisture buildup.

4. Replace the cable with a water-resistant material or short piece of cable if the power source cable is removed from the starter box coupling. The starter box must be sealed at all times. Unused cable entries should be plugged to prevent moisture buildup.

When stored outside or with inadequate power:

1. Cover the shaker with a protective tarp if possible.

2. Keep shipping bolts on the shaker at all times while in storage.

3. Replace the cable with a water-resistant material or short piece of cable if the power source cable is removed from the starter box coupling. The starter box must be sealed at all times.

4. Remove the starter box cover and spray the components with a water displacing solvent (for example, WD-40®) once a month. Allow solvent to dry then put the starter cover back on tightly. Keep all other connections intact. Use desiccant bags in starter and junction box to minimize moisture buildup.

Returning to serviceBefore returning the shaker to service after three or more months of storage, complete the following steps:

1. Remove motor covers and rotate shafts by hand.

2. Continue to rotate motor shaft while installing 5.7 grams (4 shots from a 400 gram grease gun) of Kluber Isoflex® Topas NB52 or NB152 grease into each bearing.

3. Remove shipping bolts and connect power to the machine.

4. Turn on power supply to unit.

5. Bump start the motors to check motor rotation. To bump start the motors, push the start button on the starter box, and then quickly push the stop button. Proceed as follows:

If you have the standard King Cobra separator, follow the directions in step 7 on page 18.

If you have the King Cobra separator with the tuned elliptical motion option, follow the directions in step 8 on page 18.

6. Run shaker for three hours and monitor motor bearing temperatures. At startup the motors can run hot, but after approximately three hours they should stabilize between 160 oF (71 oC) and 180 oF (82 oC).

Operation with both motors turning in the same direction results in very poor shaker performance.

General recommendations and information

Use the same mesh screen on all four panel sections. The cut point is normally determined by the coarsest mesh screen. If a coarser mesh screen is installed for any reason, it should be installed at the discharge end.

Use finer mesh screens, rather than coarse mesh screens, where gumbo or sticky clays are encountered. Finer mesh screens provide a much smoother and wetter surface than coarse mesh. Gumbo and clay tend to convey better on smoother wetter surfaces and using finer screens often provides an immediate solution to conveying problems.

Experiment with the basket angle to determine the best setting because conveyance rates vary with drilling rates and hole conditions.

Use the weir diverter plates in the backtank to balance the flow between two or more shakers hooked to a common flow line. The weir diverter plates can also be used to change the flow of the liquid onto the screen surface. Adjust the weir plates to get a less curved horseshoe to improve overall shaker performance.

If the solids being discarded are channeling to one side of the end screen, the shaker may be out of level. Correct this situation by shimming the corners of the shaker skid until it is level.

Close the backtank bypass valve during normal operation. After opening and closing the valve, check to make sure that the valve is fully seated. Gravel or hard cuttings may prevent the bypass valve from providing a positive seal.

Add replacement or makeup water while drilling as required. Adding the water to the feed tank generally reduces the mud viscosity and allows more efficient screening.

Operate the King Cobra screens wet. Running with dry screens may result in premature screen failure. Lower the deck angle or install finer mesh screens to extend the liquid pool. The end of the pool should be on the third screen.

Do not allow substantial amounts of mud to build up inside the vibrating deck. This may affect the unit’s performance. A buildup of solids on or around the motors may cause overheating.

Check basket springs for bottoming-out. Worn or weak springs may allow the vibrating deck to fully collapse the springs under heavy mud loads. This causes unusual vibration patterns and damage to the unit. Replace springs in pairs, front or rear pair, or all four springs immediately. Slow bouncing or rocking movements on the basket may indicate spring problems.

Inspect and replace worn or missing wear strips and crown rubbers. The wear strips provide a positive seal around the screen panel. Worn or missing seals result in solids bypassing into the active system. Worn crown rubbers reduce screen panel support, causing poor conveyance throughout.

Wash down screens before shutting down the unit for any length of time or before storing the screens.

Do not walk or lay tools on the screens.

Operation

Start up and operationThe following sections provide instructions for normal operation. Before operating the unit(s) make sure that you performed all steps in section titled "Installation" on page 19. The unit is factory set to provide a G-force suitable for most drilling applications. Once the unit has been installed, the only changes or adjustments that should be made are screen mesh and basket angle. Screen selection depends upon your specified drilling parameters, such as circulating volume, mud viscosity, penetration rate, etc.

Basket angleThe pivoting system is used to change the angle of the screening surfaces relative to the neutral position. The angle adjustment plates and the safety pins are used to hold the shaker at the desired angle. (See Figure 4-1.)

Figure 4-1. Angle adjustment plates and angle-indicating safety pins

It is not necessary to shut down the shaker before changing the deck angle.

To change the basket angle:

1. Remove the safety pins from the angle adjustment plates.

2. Use the hand wheel on one side of the King Cobra to adjust the basket angle.

Basket Displacement is higher during start up and shut down than under normal running conditions. Keep body parts away from basket and spring pinch points during these periods.

� Adjustment

� Safety pins

Be sure to remove the pins from both sides.

www.nov.com/brandt

Page 62: Cobra Manual

Document number M12444Revision 13Page 26 of 60

4: Operation

3. Adjust the opposite side to the same angle.

4. Replace the safety pins when the desired screen angle has been reached. Make sure the pins are in the same hole on both sides of the shaker.

5. Tighten both hand wheels.

For normal drilling conditions the unit should be operated with the basket tilted between 2° uphill and 2° downhill so the end of the liquid pool is near the discharge end of the third screen. Additional uphill incline can be used to handle an increased surge from bottoms up or an increased rate of penetration. Increasing the basket angle moves the end of the liquid pool toward the back of the basket, and allows the shaker to handle higher flow rates and/or produce drier cuttings. The disadvantage of running the basket steeply uphill is the reduced conveyance and a thicker solids bed. A thicker solids bed causes solids to be ground into smaller pieces, wears out screens faster, and may increase the amount of fine solids returned to the active mud system.

When gumbo or sticky clays are encountered it may be necessary to lower the basket angle to get the solids to convey properly. Although some baskets can be lowered to as much as 5° downhill, running the shaker at a lower angle than necessary requires use of coarser screens to prevent excess drilling fluid loss.

Screen blindingIf the screen’s openings plug (blind) with sand, there are several methods by which the screen may be unplugged. If the screens are in the unit, rub the screens in a circular motion with a cloth rag or cloth gloves. Or, with the screen removed, you may try blowing out the solids with high-pressure air or water from the bottom.

Changing to a finer mesh screen may cause the near size sand that is blinding the screens to be removed and discarded. Changing to a larger mesh screen may solve the blinding problem, but increases the amount of solids returned to the active system.

Salt-water muds sometimes cause calcium deposits to coat the wires in the screen. As the layer of calcium increases in thickness around the wires, the openings become plugged off. This usually results in flooding. Steam cleaning usually removes the calcium deposits.

Cuttings are generally dry enough for most applications when the end of the liquid pool is near the end of the third screen.

Never use a wire or stiff fiber brush on the screens.

Often it is necessary to experiment with several mesh sizes to minimize blinding while drilling through unconsolidated sand formations. As a general rule, try finer screens first.

Maintenance & Repair

MaintenanceThe King Cobra separator requires very little maintenance. However, there are several maintenance checks that, if done on a regular basis, provide extended service and performance.

LubricationMotorLubricate each bearing on the motors once every operating month (750 hours) per the following instructions. Use only Kluber Isoflex® Topas NB52 grease (P/N 46AS) for operation in cold ambient temperatures of -20 °F to +50 °F (-29 °C to +10 °C). You may use either NB52 or NB152 for ambient temperatures of 50 °F to 100 °F (10 °C to 38 °C). For hot ambient temperatures above 100 °F (38 °C), you must use Isoflex Topas NB152 grease (P/N 46AY).

1. Clean vibrator case around grease plug with a clean shop towel.

2. Remove grease plug from vibrator housing.

3. Install 1/8″ NPT grease fitting (P/N 33B) into the vibrator housing. Always use a new grease fitting. Even small amounts of another grease may cause a negative reaction with the Isoflex grease.

4. Install 5.7 grams (0.2 oz.) of grease with a grease gun into each grease fitting. 5.7 grams equals 4 shots from a 400 gram grease gun.

5. Replace the grease fitting with the grease plug.

6. Do not lubricate for another operating month. Too much grease will ruin the motor and void the warranty.

If motor has been running and has not been lubricated for more than three months, put 20 shots in each bearing and then four additional shots each month per the above instructions.

Using any grease other than Kluber Isoflex® Topas will void the motor warranty.Do not mix Isoflex grease with any other grease.

Do not leave the grease fitting(s) in the vibrator housing.

12. Bump start the motors to check motor rotation. To bump start the motors, push the start button on the starter box, and then quickly push the stop button. Proceed as follows:

If you have the standard King Cobra separator, follow the directions in step 7 on page 18.

If you have the King Cobra separator with the tuned elliptical motion option, follow the directions in step 8 on page 18.

13. Reinstall the motor weight covers.

14. Return the shaker to service.

15. After 30 minutes of operation, re-torque the motor mounting bolts.

Replacing seal strips and crown rubbersTo replace long wear strips:

1. Remove the old fasteners with a screwdriver and back-up wrench and remove the seal.

2. New seals should be formed prior to installation. When received from the factory, they are straight, but should be bent upward at each bolt hole.

3. Tighten the seal from the center outwards, alternating from side to side. Over tightening the seal causes deformation and forms a gap between the frame and the seal, which can lead to screw installation problems or may cause leakage.

To replace side pinned wear strips and side wear strip (obsolete):

1. Remove the hardware and seal.

2. Clean all mating surfaces thoroughly.

3. Insert the new short wear strips with new fasteners, but do not tighten. Note that pin is located off center. The clean strip must be mounted with the pin closest to the basket wall.

4. An alignment tool pin is required to set the pin spacing.

5. Place the alignment tool over the pins on both wear strips with the butt of the extended end against the basket wall. The other end does not touch the basket wall.

6. With the alignment tool still in place, tighten the hardware on one strip and then the other. The alignment tool may then be removed.

7. Proper installation of the screens is now possible.

To replace crown rubbers:

1. Remove the crown rubbers.

2. Clean the metal support thoroughly.

3. Replace with new crown rubbers.

Operation with both motors turning in the same direction results in very poor shaker performance.

Installing Vibrator

Mounting vibrator onto structure

IMPORTANTRead entire section before beginning work. This manual provides instructions for installations onto steel bins and hoppers only. For other installations, call Martin Engineering or a representative.

CAUTION!

If installation instructions are not followed, structure and vibrator can be damaged. Abusing or dropping vibrator will accelerate wear and cause bearing damage.

1. See Figure 1. Locate vibrator in lower 1/4 to 1/3 of structure slope length. If second vibrator is required, mount 180° from first vibrator and halfway up slope.

Figure 1. Locating Vibrator on Hoppers

CAUTION!

Never weld structure with vibrator mounted and wired. Welding may cause damage to motor windings and bearings.

IMPORTANTThe object of rotary vibration on bins, hoppers, and chutes is to transmit vibration through the wall into the product contained inside. If structure is not made rigid, vibrator may draw high amperage and move material less efficiently.

Make sure structure is free of paint before mounting vibrator.

2. If using customer-supplied mounting plate to mount vibrator onto structure, do the following:

a. Make sure plate is at least the size of vibrator base.

b. Locate plate so that vibrator can be positioned as shown in Figure 2.

c. Weld mounting plate onto structure.

Adjusting eccentric weights

NOTEAll Vibrators have one set of eccentric weights on each end of shaft. Eccentric weights are set at 50% at factory. See Figure 10.

The percentage increments on the weight adjustment disks are percentages of the total force pounds listed on the nameplate. For example, if the nameplate shows 8340 lb, setting the weights to 50% would produce 4170 pounds of force.

IMPORTANTFor the most efficient operation, vibrator eccentric weights should be adjusted to the lowest force setting required to move the material. This will increase vibrator life and reduce energy costs.

WARNING!

Before adjusting eccentric weights, turn off and lock out/tag out energy source to vibrator.

1. Turn off and lock out/tag out energy source to vibrator according to ANSI standards (see “References”).

2. Remove weight cover.

3. Loosen nut or screw (A, Figure 9) so adjustable weight (B) will rotate around shaft (C).

Figure 10. Adjusting Eccentric Weights

NOTEThe fixed weight is attached to the shaft. The adjustable weight rotates around the shaft. The weight adjustment disk will be attached to either the fixed or the adjustable weight.

Initial start-up/checking line current

1. Close power supply disconnect switch and allow vibrator(s) to operate.

2. If vibrator makes unusual or excessive noise, make sure mounting bolts are tight and mount welds are not damaged.

WARNING!

Vibrator may produce loud noise during operation when mounted on structure. See OSHA 1910.95 for guidelines. If required, wear ear protection to avoid impairment or loss of hearing.

3. Check decibel level of vibrator noise during operation. See OSHA 1910.95 to determine whether noise exceeds safe limits. If required, wear ear protection to avoid impairment or loss of hearing.

CAUTION!

If vibrator is operated continuously with line current above nameplate rating, vibrator can be damaged.

4. After a few hours of operation, check each line current. If reading is higher than nameplate rating, check for correct phase voltage ensuring that it is correct and balanced. If phase voltages are correct (± 10% of nameplate rating) and balanced, recheck wiring, ensure that mounting bolts are correctly installed, or contact Martin Engineering for assistance. After making adjustments, check line current again to ensure line current does not exceed nameplate rating.

5. After first 8 hours of use and periodically thereafter, check mounting bolt torque and tighten if necessary.

Variable frequency inverter

CAUTION!

All vibrators can be supplied with a pulse-width modulated variable frequency inverter. NEVER operate the vibrator at a frequency higher than that specified on the nameplate. Damage to vibrator can result.

Do not operate vibrator at frequency higher than specified on nameplate. Throughout frequency range, verify that each line current does not exceed current rating on nameplate. If reading is higher than nameplate, consult inverter manual. If necessary, adjust inverter. After making adjustment, check line current again to ensure line current does not exceed nameplate rating.

Maintenance

Lubricating vibrator IMPORTANT

Read entire section before beginning work. Allow vibrator to cool to ambient temperature before working on it.

NOTEAll vibrators are lubricated at the factory.

CAUTION!

Use only prescribed grease in vibrator. If a different grease is used, vibrator can be damaged and warranty will be void.

Use only prescribed amount of grease to lubricate vibrator. Too much grease will cause bearings to overheat and result in premature bearing failure.

1. Lubricate the vibrator with Kluber Isoflex Topas NB 52 grease according to Table III.

Table III. Lubrication Schedule

CAUTION!

For 3600 rpm machines operating continuously or for long periods of time, reduce lubrication time and amount as described in step 2. Failure to do so could result in premature bearing failure.

2. If vibrator housing temperatures exceed 194° F (90° C), cut lubrication time and amount in half for every 18° F (10° C) increment that meets or exceeds 194° F (90° C).

NOTEKluber grease may be purchased from Martin Engineering by calling 800-544-2947 or from Kluber Lubrication by calling 888-455-8237.

3. Lubricate with Kluber Isoflex Topas NB 52 grease only. Lubricate as follows:

a. Clean vibrator at each pipe plug in housing to remove dirt and debris. Remove pipe plug. Insert 1/8 in. NPT grease fitting. Add grease. Remove grease fittings; tightly replace pipe plugs. (Use anti-seize compound on threads.)

Repairing vibrator and replacing bearings

CAUTION!

Repairing vibrator yourself during the warranty period may void the warranty. Contact Martin Engineering if motor needs repair.

If vibrator needs repair or if bearings need to be replaced, call your local representative or Martin Engineering at 800-544-2947 for instructions.

Inspecting vibrator

At least quarterly, inspect cable and connections as follows:

WARNING!

Before inspecting vibrator, turn off and lock out/tag out energy source to vibrator.

1. Turn off and lock out/tag out energy source to vibrator according to ANSI standards (see “References”).

2. Inspect cable for damage including cuts and abrasions. Replace if damaged.

3. Inspect ground connection. Make sure resistance from ground connection to vibrator enclosure does not exceed 0.1 ohm. Ensure screw on ground terminal is tightened to proper torque (see Table I).

4. Make sure all nuts on connections on terminal block are tightened to proper torque. Do not overtighten (see Table I).

5. Check mounting bolt torque. See Table I: “Mounting Bolts and Torque Requirements”.

Product Information

DescriptionThe Desander hydrocyclone, designed to remove sand-size particles, and the Desilter hydrocyclone, designed to remove silt-sized particles, should be the second stage of a solids removal program for unweighted muds. To achieve maximum benefit from these units, install them as recommended.

These specially designed hydrocyclones are made from a durable polymeric material developed exclusively for NOV Brandt. The involute feed entry design (rather than the conventional tangential entry commonly used in the industry) increases the hydrocyclones' handling capacity up to 25%. Other advantages are more efficient drilled solids separation, less drilling fluid is discarded, and reduced wear at the feed inlet.

The Hydrocyclone Systems consist of an assembled hydrocyclone, a separate overflow and underflow manifold, and a discard trough for the underflow. The hydrocyclones are available as a 12” Desander, 10” Desander, and 4” Desilter. The size designation is the inside diameter of the hydrocyclone. In general, the cut point of the hydrocyclone decreases as the inside diameter decreases.

The number of hydrocyclones should be selected to process approximately 110 - 125% of the maximum circulating rates expected in top hole drilling. This will ensure treatment of 100% of the circulating volume containing formation contaminants.

Equal importance should be given to selecting a suitable centrifugal pump and prime mover (engine or electric motor) that will deliver the required flow rate and feet of head/pressure to the feed manifold.

Properly installed, maintained and utilized, the hydrocyclone will reduce rig pump maintenance, improve penetration rates and improve hole conditions.

A properly installed and correctly operated hydrocyclone will be a cost effective mechanical device for the reduction of undesirable contaminants in following mediums.

Installation

The hydrocyclones should be mounted so that the feed manifold is ABOVE THE MAXIMUM mud level in the tanks. This prevents the mud from the tanks being siphoned through the cones and into the waste pit when the feed pump is shut down.

A centrifugal pump should be used to feed the hydrocyclones. A centrifugal pump will deliver a smooth even flow to the feed manifold. A reciprocating pump should not be used due to delivery fluctuations.

Proper solids control system installation should have the Desander’s centrifugal pump taking suction from the closest compartment possible downstream of the rigs' primary shakers. The Desander’s overflow mud should discharge into the next down stream compartment where the Desilter’s pump will take suction.

Hydrocyclone installation requirements are basically the same, and must be adhered to if optimum efficiencies are to be realized.

Centrifugal Pump Installation1. Each hydrocyclone manifold should have its own centrifugal pump dedicated to it’s

operation and sized correctly to satisfy the hydrocyclone’s pressure and volume requirements in order to achieve optimum operating performance.

2. The centrifugal pump should be located below the fluid level of the pit to allow for a flooded suction and to minimize pressure losses. A pump that must be mounted above the fluid level should include a foot valve.

3. The suction line to the centrifugal pump should be equal to or larger than the diameter of the pump’s inlet. If the suction line is longer than 10 feet, then the suction line must have a 2-inch larger diameter than the pump’s inlet to prevent loss of pressure head. The larger suction line should be connected to the pump suction with an eccentric reducer so that the top of the larger line is level with the top of the pump intake.

4. To minimize the risk of plugging the pump’s suction or causing damage to the pump with trash, the suction intake inside of the compartment should have an elbow facing down about 4 to 8 inches above the compartment bottom. If the suction is too high, a vortex will occur and draw air into the pump, resulting in poor hydrocyclone performance.

Pump Discharge/Hydrocyclone FeedProperly size the feed and suction lines. Oversized pipes will result in solids settling and undersized pipes will result in restricted flow and decreased pipe life. The feed line from the pump to the 4" hydrocyclone manifolds should be at least 6 inches in diameter, and 8 inches in diameter to a 12" or 10” hydrocyclone. Utilize long radius elbows to minimize pressure losses and wear in the lines.

Page 144: Cobra Manual

Document number M9319Revision 8Page 12 of 48

3: Installation

OverflowThe overflow line (clean mud) should be directed to the next downstream compartment from the units suction. The overflow should not slope upward. This will prevent a possible back pressure in the hydrocyclone resulting in whole mud losses out the apex.

The overflow line should not extend below the highest expected mud level. A splash plate or opened tee installed at the overflow’s exit (discharge) will minimize aeration of the mud that would adversely affect the pump pressure. If possible, the overflow line should slope downhill at 45° to allow partial pipe flows that will prevent a siphoning effect.

ValvesOne valve in the pump suction line for pump repair and one in the discharge line to permit surge free startup operation will be adequate. Locate the pump so that the shortest suction line and the most direct discharge line route is accomplished, using as few bends and fittings as possible to reduce the frictional line losses.

Pump SuctionTo minimize operational problems, use these guidelines when designing or installing the suction line piping system.

1. One suction pipe for each pump.

2. Have a flooded suction. Oilfield centrifugal pumps are not self-priming.

3. Size the pipe diameter to produce 4 feet per second velocity or more.

4. Locate the pump as near the tank as possible. The shortest suction pipe produces the least friction losses.

5. Use straight pipe for smooth flow into the pump.

6. Properly sized the fittings for low friction loss.

7. Install a shut off valve near the tank for working on the pump.

8. Weld a flat plate on the tank wall just above the suction pipe to prevent vortexing.

9. Install an easily cleaned strainer for all mud going to the suction.

10. Avoid whirlpools, air leaks, air traps, and suction lift.

11. Install the suction near the bottom of the tank using an elbow and flare.

Operation

PrinciplesThe three most often mentioned components of the hydrocyclone are: the FEED, the UNDERFLOW, and the OVERFLOW.

Fluid entering the hydrocyclone is the “feed”. The feed opening (inlet) is at the top end of the feed chamber and enters the hydrocyclone at a tangent or involute to the feed chamber wall.

The solid / liquid slurry that exits the bottom of the cone is the solids discharge, or "underflow".

The liquid discharge that exits the top of the hydrocyclone is the "overflow". The overflow carries the light fraction (cleaned liquid) of the separated mud to the overflow manifold, and returns it to the mud system.

www.nov.com/brandt

Page 146: Cobra Manual

Document number M9319Revision 8Page 14 of 48

4: Operation

As the fluid enters the hydrocyclone, it is propelled into a high velocity spiral moving around the "vortex finder" which extends down from the overflow exit. Actually two spirals are created, one moving downward along the wall of the hydrocyclone while the other moves upward through the core of the hydrocyclone towards the overflow opening. The centrifugal forces and inertia effect cause the solids to settle outward toward the hydrocyclone wall in a downward spiraling motion.

The solids settle according to weight and size, and with the density range of the solids normally present in drilling fluids being rather small, the size usually dictates which particles will reach the wall first. The liquid and most of the fine solids from the inner spiral move upward and outward into the overflow manifold and back to the system. The central air core in this spiral creates a low-pressure region that results in the suction that can be felt by blocking the apex opening with your finger tip.

The hydrocyclones' ability to separate the solids efficiently is dependent on the following factors:

1. Fluid properties

2. Particle properties

3. Flow parameters

4. Hydrocyclone parameters

This hydrocyclone design is referred to as "BALANCED". The solids traveling downward to the apex area will become highly concentrated due to the decreasing available area. The solids will exit in a vigorous "spray" discharge ("UNDERFLOW") . As previously mentioned, there will be an air stream (suction) entering the apex. These combined features are the ideal mode of operation of the hydrocyclone.

The “balance" design is unique in that, as long as the solids present in the feed mud are within the hydrocyclones' size range, the hydrocyclone will discard the solids. When the solids are too small or low in concentration, the hydrocyclones' "underflow" will discharge a minimal amount of liquid mud.

The efficiency of the hydrocyclone is affected by the flow rate, entering fluid velocity and pressure drop across the hydrocyclone. The hydrocyclones' efficiency will increase as the particle density and/or diameter is increased. As the fluid density and/or viscosity increases, the efficiency is decreased.

To maintain underflow with a density weight of 1.5 ppg more than the feed slurry, a smaller apex opening may be needed. It is difficult to estimate accurately the underflow discharge rate. However, it can vary between 1% to 5% of the feed volume to the unit.

A hydrocyclone discharging in a spray (resembling a hollow cone or umbrella) will achieve maximum solids removal. If the hydrocyclone becomes overloaded with entering solids, the solids are detained in the apex area resulting in reduced separation and rate of removal. The solids that would normally exit the apex are now returned to the system via the vortex finder or overflow. The solids that do report to the underflow will now be discharging in what is referred to as a "Rope Discharge".

The "Rope Discharge" underflow may contain as much as 30% more solids than a "Spray Discharge" but the actual rate of discharge is so restricted that the hydrocyclones may only discard 50% of the solids that it would while operating in a "Spray Discharge"

Document number M9319Revision 8Page 15 of 48

4: Operation

Rope versus Spray Discharge1. A rope discharge will not remove solids as well, even though the density is heavier. It looks

more efficient, but is not.

2. The system’s mud weight will increase faster due to the solids reporting to the overflow (density increase). Also, in unweighted systems the well bores filter cake will contain unwanted solids.

3. Only with additional mechanical equipment and/or through expensive dilution can the solids returning to the system be removed when roping occurs.

4. Premature wear at the apex, vortex finder, upper hydrocyclone body and rig pump fluid end parts will result, if a roping discharge is not rectified quickly.

This example above indicates that the hydrocyclone leaves 29,952 lbs or 33 BBLS of solids in the system daily when it ropes verses spraying. A mud system weight of 9.2 ppg with 6.5% solid content, would require 475 BBLS of dilution water for these solids to maintain the system's desired mud weight.

(33 BBLS/.065 = 508 BBLS - 33 BBLS = 475 BBLS water)

Centrifugal PumpCentrifugal pumps produce pressure by accelerating fluid to the impeller tip speed. The casing converts this velocity into pressure. The pressure produced by the centrifugal pump acts as if it was coming from a water tower. The pressure in PSI varies with the weight of the fluid, the same as it would if the water tower is filled with different fluids. “Pressure head” of the fluid remains constant at any density. A pressure head of 75 feet is required for maximum hydrocyclone efficiency.

Centrifugal pumps produce pressure by converting liquid velocity to static pressure. The system back pressure must equal the pumps produced head. The system pressure loss is the total of the elevation difference plus friction loss. The volume pumped by a centrifugal pump increases until the sum of elevation and system friction head loss equals the output head of the centrifugal pump on the impeller performance curve. Using a larger pipe will lower friction, allowing the pump to increase in volume.

When operating the centrifugal pump, the head will remain unchanged; pressure readings, on the other hand, will change if the weight of the fluid being pumped changes.

4: Operation

OperationWhen drilling the hydrocyclones should operate with a spray discharge for maximum efficiency. A slight suction at the apex discharge opening is proof of spray discharge. If suction does not exist, the hydrocyclones are "roping" and the apex needs to be opened up. If the hydrocyclone continues to rope with the apex wide open, consult the Troubleshooting Section for the cause and solution.

If flow rates indicate that blanking of hydrocyclones is necessary, blank off individual cones starting from the feed end of the header.

Start-Up ProcedureCheck pump suction, if visible. Clear trash and debris.

1. Open pump suction valve. Do not start pump with suction valve closed or pump damage will result.

2. Discharge valve should be closed. If diesel pump is used, check that throttle is in idle position. Damage and injury may occur if diesel pump is started at full throttle.

3. Start pump and slowly open discharge valve to full open position.

4. Check pressure on Feed Gauge. The gauge needle should be in the area corresponding to the mud weight. If the original feed gauge supplied with the unit is replaced with an ordinary pressure gauge, proper pressure is four times (4 X) mud weight (in ppg). Low pressure will cause poor separation and high fluid loss. Excessively high pressure will cause high rates of hydrocyclone wear. When testing with water the feed pressure is 32 PSI.

5. Check the hydrocyclone underflow for a spray discharge. If hydrocyclones have a rope discharge or no discharge, consult the Troubleshooting Section.

Example:

PSI = Mud Weight x 0.052 x Head (in feet)

Head = 75 feet

If: Mud Weight = 9.5 ppg

PSI = 9.5 x 0.052 x 75 = 37 psi

If: Mud Weight = 12 ppg

PSI = 12 x 0.052 x 75 = 47 psi

Do not operate hydrocyclones with a rope discharge because poor solids removal and hydrocyclone damage will occur.

4: Operation

Shutdown Procedure1. Turn pump off. If diesel pump is used, close throttle before shutoff. Do not use the

emergency kill switch (if supplied) for normal shutdown.

2. Close pump discharge valve.

3. Close pump suction valve.

Hydrocyclone Blanking1. Stop unit. Remove the clamp from the feed inlet of the hydrocyclone.

2. Remove clamp from the overflow elbow at the header. Support the weight of the hydrocyclone or damage and injury may result.

3. Remove the hydrocyclone and overflow elbow.

4. Install blanks and clamps. Start unit.

Apex AdjustmentHydrocyclones operated improperly will cause poor separation and should be adjusted or replaced as soon as problem occurs. Only the 12” hydrocyclone allows for apex adjustment. The 10” and 4” hydrocyclone are shipped from the factory with the optimum apex.

12” Desander Apex AdjustmentThe non-adjusting apex bushing is located in the adjusting nut at the bottom of the desander hydrocyclone. A bushing with 1-3/4” internal diameter is installed at the factory. 1-1/2” and 2-1/8” apexes are also available. If a change is required:

1. Remove the hydrocyclone apex nut by turning clockwise.

2. Remove the apex bushing from the apex nut.

3. Install proper size apex bushing.

4. Install the hydrocyclone apex nut.

10” Desander and 4” Desilter Apex AdjustmentThe apex adjusting bushing is located in the adjustable nut at the bottom of the desliter hydrocyclone. Proper discharge is achieved by twisting the adjustable nut as indicated below.

1. Start feed pump and check for spray discharge.

2. If excessive liquid loss occurs, tighten the adjusting nut to close bushing. Apex size will be smaller.

3. If roping occurs, turn clockwise to open bushing. Apex size will be larger.

Do not cross-thread. Hand tighten only.

Over adjusting may cause roping and dry plugging of hydrocyclones. Do not use a wrench on the adjusting nut. Hand tighten only.

If roping is not eliminated, remove the nut and bushing.

Troubleshooting

TroubleshootingFor such a basic appearing device, the hydrocyclone can display many varied problems. The following six (6) are the most frequently experienced in the operation of the hydrocyclones.

Symptom Probably cause Solution

Low feed pressure. Improper head pressure. Check with manufacturer for proper head pressure required and adjust pump as necessary. Pump impeller sizing must make up for variable pressure losses in the piping.

Plugged pump suction. Clean screen. Check for obstruction in pump and line. Make sure valves on suction and discharge are open.

Other equipment operating. Check that pump is not operating other equipment simultaneously.

Air locked pump. Prime pump. If suction is flooded, stop and restart the pump.

No discharge. Plugged apex. Unplug the apex.

Apex too small. Change apex to larger bore (12” hydrocyclone only).

Solids below hydrocyclone’s cut point capabilities.

No problem, working fine.

Siphon on overflow. Install vacuum breaker at highest point on overflow. Remove pipe plug in top of header and install pipe 6" to 8" long.

www.nov.com/brandt

Page 152: Cobra Manual

Document number M9319Revision 8Page 20 of 48

5: Troubleshooting

Discharge roping. Undersized apex. Change apex to larger bore (12” hydrocyclone only).

Check pump specification, feet of head too low.

Refer to section titled "Centrifugal Pump" on page 15.

Mud viscosity very high. Run centrifuge.

Solids overloading. Check that upstream equipment is operating properly.

Discharge weight near that of feed weight.

Apex too large. Reduce size.

Low silt concentrations. Evaluate economics of equipment.

Discharge weight greater than normal.

Roping discharge due to solids overloading.

Increase apex opening.

Check that upstream equipment is operating properly.

Unusual discharges. Cone shape or liquid discharge.

Feed inlet partially plugged causing a reduced feed velocity.

No discharge. Remove and clear obstacle.

No vacuum or flooded liquid rope discharge.

Feed completely plugged; can cause good overflow mud to enter hydrocyclone from the overflow manifold resulting in whole mud losses.

Plugged apex. Typical when roping is allowed to continue. Solids build-up in the hydrocyclone and overloads at the apex. Entering solids will report to the overflow and back to the mud system. Plugged apex will cause premature wear on the hydrocyclone and excessive wash out on overflow fittings.
