GENERAL

Although HIBON blowers are sturdy precision-engineered machines which are quality controlled toprevent manufacturing defects, there are several relatively simple but basic installation andmaintenance procedures that must be observed to ensure optimum performance. As there is no

guesswork in the manufacture of these highly advanced units, there must be none in preparing themto get the job done in the field. It is the purpose of this manual to help you properly install, maintain

and service your HIBON blower. Follow the instructions carefully and you will be rewarded with yearsof trouble-free operation. Some principles of correct installation and maintenance are identical or

similar for all series of HIBON blowers. In such cases instructions for all models are treatedcompositely in various subsections.Some of the data is particular only to the specific series described in the cover of this manual. Hence,

it is important that no section be overlooked when preparing to install your blower.The manual is prepared in sections covering: Operation, Installation, Maintenance, and Trouble shooting

Before delivery the blowers are subjected to a run test in our factory. The test record may be sent on

request. The oil casings are drained after the test.The blowers are delivered WITHOUT OIL.Each blower is provided with a name plate showing the machine type and the serial number. Anyunauthorized modification of the machine or any failure to observe the installation or operation require-

ments specified in this Instruction manual shall be the sole responsibility of the client and shall cancelany guarantee rights.

OPERATING CHARACTERISTICS

Read the appropriate working instructions BEFORE running the machine.The rotary lobe blower is a positive displacement type unit, whose volumetric capacity is determinedby the size of the unit, the operating speed, the differential pressure and the atmospheric conditions.It employs two bi-lobe or two tri-lobe impellers mounted on parallel shafts and rotating in opposite

directions within a cylinder closed at the ends by headplates. As the impellers rotate, air is drawn intoone side of the cylinder and forced out the opposite side against the existing pressure. Therefore, the

pressure developed depends on the resistance of the discharge system.Effective sealing of the blower inlet area from the discharge area is accomplished by use of very small

internal clearances. The resulting absence of contacts between moving parts eliminates the need forany internal lubrication. Clearances between the impellers during rotation are maintained by a pair ofaccurately machined timing gears mounted on the two shafts extended outside the air chamber.

No attempt should ever be made to control capacity by means of a throttle valve in the intakeor discharge piping. This will not only increase the power load on the driver, but can also overload

and seriously damage the blower. Likewise, if a possibility exists that flow to the blower inlet maybe cut off during normal operation of a process, then an adequate vacuum relief valve or protection

switch must be installed near the blower. A pressure type relief valve in the discharge line near theblower is also mandatory for protection against cut-off or blocking in this line.When a belt drive is employed, blower speed can usually be adjusted to obtain desired capacity by

changing the diameter of one or both sheaves. In a direct coupled arrangement, a variable speedmotor or transmission is required, or excess air may be blown off through a manually or controlled

unloading valve and silencer. If returned to the blower inlet, air must go through a cooled by-passarrangement.

Before making any changes in blower capacity, or operating conditions, contact the nearest

Hibon Sales Office for specific information applying to your particular blower. In all cases, operatingconditions must be maintained within the approved range or pressures, temperatures and speed. Also,

the blower must not be used to handle air containing liquids or solids, since serious damage tothe rotating parts will result.

TRANSPORT AND STORAGE

Before packing and shipment of the machine, all external machined parts are coated with a rust pre-ventive film and the nozzles are closed with protective caps to avoid any introduction of foreign matter

or water.

When receiving the machine, it must be checked for any damages due to transport. Before any

handling, all contact surfaces must be protected with wood pieces and appropriate slings or cablesshould be used. All base plates have four lifting lugs. The blower, when alone, may be handled with

slings under the side plates or under the cylinder (blower body) on both sides of the flanges. Neveruse the integral cast lugs of side plates and gear castings.

The blower and accessories should be stored in a dry, heated and suitably protected place. The rustpreventive coating or oil shall be renewed or changed, if necessary.During storage, it is essential to prevent the machine from being subjected to vibration produced by

the operation of nearby machines and propagated via the bearing surfaces. Vibrations applied for longperiods could damage the machine and motor bearings.

For a long storage time : - Loosen any transmission belts

- Fill the castings with rust preventive oil up to sight glass, and rotate the

shaft a few revolutions

- Spray rust preventive oil in the compression chamber

- Rotate the shaft three or four revolution every two weeks to avoid anydamaging of the bearing.

- It is also recommended to place a bag of silica gel or another groscopicsubstance inside the inlet opening and inside the outlet opening, imme-

diately replace the respective covers.

At the end of the storage time, the compression chamber should be cleaned using a solvent (Alcohol,

White Spirit). The casting must be drained.

OPERATION

1. Two lobe blowers

The basic operation of a rotary two lobe type positive displacement blower is illustrated (Figure 1) asfollows :

In position 1Air flow enters from the right in the inlet side

towards the left to the discharge side of theblower. With the lower impeller rotating clock-

wise, (changing the rotation will change theflow direction) the blower is delivering a known

volume (A) to the discharge, while space (B)between the upper impeller and cylinder wall is

being filled.

In position 2

Counterclockwise rotation of the top impellerthen traps equal volume (B), and further rota-

tion delivers it to the discharge in Position 3.

In position 3

At the same time, another similar volume is

forming under the lower impeller, and will bedischarged when rotation reaches Position 1again.

One complete revolution of the driving shaftalternately traps four equal and known vol-

umes of air (by each impeller) and pushesthem through to the discharge. The volumetriccapacity of a lobe blower operating at a con-

stant speed therefore remains relatively inde-pendent of reasonable inlet or discharge pres-

sure variations. The blower is used as an airblower, and may be used for handling air or

gas in either pressure or vacuum applications.

2. Three lobe blowers

The Hibon three lobe rotor blowers benefit from the latest technological developments which providesthem with several major advantages:

• Better balanced and more resistant rotors for better withstanding of fatigue.• Progressive unloading channels reduce pulsation. Fundamental frequency is increased to six timesthe revolution making noise attenuation easier.

• Volumetric efficiency is increased.The basic operation of a rotary three lobe type position displacement blower with precompression

passage is illustrated (Figure 2.) as follows:

In position 1

Flow is top to bottom from blower inlet to dis-charge, the left impeller is mounted on the dri-

ving shaft then rotates counterclockwise and

delivers a volume into the discharge pressureside. At the same time, space (B) between theimpeller and the cylinder wall is filling with

another and equal volume at inlet pressure. Itis about to be sealed off by the counterclock-wise rotation of this impeller. The space (C) is

progressively filled and compressed with dis-charge volume through the precompression

passage.

In position 2The inlet area sealed in (B) and dischargepressure starts to enter space (A) through the

precompression passage as rotation continues.

In position 3Volume (C) is delivered to the discharge pres-

sure side in the same manner as volume (A).Because of the almost complete pressureequalization through the precompression pas-

sage, no sudden shock will occur.

In position 4The inlet area volume sealed in (C) and the

discharge pressurized volume entering space(B) start to enter through the precompressionpassage in (C). Volume (A) is delivered to the

discharge side and the volume in (B) will alsostart delivering with (A) as soon as the rotation

reaches the outlet side.

either side/side or top and bottom connection.

HEALTH AND SAFETY - RECOMMENDATIONS - ROTATING - MACHINERY

• The Health & Safety at Work Act requires

manufacturers to fit guards on all exposedrotating shafts, glands, couplings and belt

drives, etc... It is incumbent upon the opera-tor to ensure that these are in position beforethe machine is operated.

• The noise levels emitted by rotary machinerymay vary depending on rotational speed,

application, and environment, and on certaininstallations these noise levels can be suffi-

ciently high to cause hearing damage ifexposure is prolonged. On such installations,correct hearing protection must always be

worn if working in the immediate vicinity.

• Rotary equipment may cause severe injuries

if incorrect clothing is worn when mainte-nance work is attempted if machines are in

operation.

• Blower casing and associated piping and

accessories may become hot enough tocause major skin burns on contact.

DON’T Run the machine unless all

GUARDS are in position

DO Wear suitable HEARING PROTECTIONwhen working in the vicinity of noisy

machinery.

DO NOT Attempt maintenance work or

adjustments unless wearing suitablePROTECTIVE CLOTHING.

• GENERAL

It is important that plant operators are made

aware of the responsibilities incumbent uponthem to take all necessary precautions to ensure

their health and safety, and also that plant author-ities implement the procedures necessarytowards this end, i.e. by providing relevant pro-

tective clothing and devices, and by bringing tothe attention of the operators the official safety

recommendations.

• DON'T Attempt any maintenance work untilall electrical gear has been isolated.

Isolate all electrical supplies before removing anyguards, covers or accessories from any rotating

machinery installation. Before re-connecting the

electrical supply ensure that all guards, coversand accessories are correctly replaced.

• DO Ensure that maintenance work onmachine handling TOXIC materials is carried

out in a well-ventilated atmosphere whentoxic fumes have been purged. Also observe

all necessary FIRE precautions.

On installations involving toxic materials orvapors, operators should ensure that they arefamiliar with the regulations relating to contact

with these materials and vapors, and also the cor-rect procedures in case of fire.

• DO Ensure that all RELIEF VALVES and otherSAFETY DEVICES are kept operative and aretested regularly.

Rotating machinery installations in the Rotary

Compressor, Liquid Ring Pump and Rotary Lobecategory should be equipped with standard safe-

ty devices to prevent the units being operated out-side their design range. These safety devicestake the form of spring or weight loaded relief

valves for pressure, spring loaded valve only forvacuum relief, high pressure, high vacuum and

high temperature switches, low water flow andlow oil level switches etc... and normal installa-

tions can include individual or multiple combina-tions of any or all of them.

These would normally be supplied pre-set from

multiple combinations of any or all of them. Theywould normally be supplied pre-set from the fac-

tory, or they would be finally set, on site, duringcommissioning.

Unauthorized adjustment of any of these safety

devices can lead to a potentially dangerous oper-ating condition.

• DO NOT LEAVE ELECTRICAL GEAR LIVE

AND UNATTENDED WITHOUT A SUITABLEWARNING NOTICE.

Distinctive warning notices must be provided forposting in a conspicuous position to any piece of

electrical equipment or machinery on which main-

tenance is being carried out, and which, for anyreason whatsoever, is liable to be left unattendedwhile in a live condition.

• OTHERS

Stay clear of open inlet piping of pressure blowers

and the open discharge blast from a vacuumblower.

Place a strong coarse screen over on an openinlet piping.Do not use an air blower on explosive or

hazardous gases, unless the system is designedfor the application.

INSTALLATION

EQUIPMENT CHECK

Before uncrating, check the packing slip carefully to assure receipt of all parts. Small, but importantaccessories - relief valves, for instance - can easily be lost. Note that all accessories are listed as sep-arate items on the packing slip. After confirming all items that are shown on the packing slip are includ-

ed, uncrate carefully. Register a claim with the carrier for lost or damaged equipment immediately.

PROTECTION AND CLEANING

The internal surfaces of all HIBON units are mist sprayed with a rust preventive to protect the machineduring the shipping and installation period. This lubricant does not have to be removed upon initialstart-up. It may be removed with a safety solvent for special application: pour the solvent slowly into

the inlet side of the machine while running until the unit is visually clean.

The shaft extension is protected with special paint which can be removed with any standard solvent.

Blower inlets and outlets are temporarily capped to keep out dirt and other contaminants during ship-ping. These caps must be removed before start-up.

LOCATION

If possible, install the blower in a light, clean, dry place with plenty of room for inspection and mainte-nance. Units mounted on steel and other structural materials should be set as close as possible to

supporting beams or walls. For an outdoor location please consult the factory for recommendations.

FOUNDATION

The concrete foundation should be solid, levelled and as smooth as possible, and at least 1.5 times

the weight of the equipment. The foundation should be raised 150 mm (6'') for cleaning purposes. SeeAPPENDIX C for type of foundations and installation.

LEVELING AND ALIGNMENT

Blower equipment with a thrust or locking bearing assembly will function without exact leveling. Bycontrolling the lateral position of the impellers in relation to the headplates, the main purpose of the

thrust assembly is to counter thrust not normally found in standard applications. This feature preventsthe impellers from floating against the headplates.

However, normal precautions should be taken to prevent strain or case warpage.

Blowers shipped with a mounted drive must be checked for alignment before start-up. Severe mis-handling during transportation can cause misalignment.

ANCHORING

The package can be properly anchored to the concrete base or mounted on a set of antivibration pads.


10/55

rev 01, 15/08/98Page 10 of 15


ROTATION

Rotation of the motor must be checked before installing the blower drive.

Blowers are built for reversible operation unless a rotational arrow is located above the drive shaft. Ifan arrow appears, the unit is timed for rotation indicated and cannot be reversed unless the unit is

retimed (See retiming instruction).

DRIVE

V-Belt : Faces of belt sheaves must be in alignment. Sheaves should be mounted on the blower shaft

as close as possible to the drive cover. Mount the driver on slide rails to permit proper belt installationand take-up (SEE APPENDIX A). Check rotation of the motor before installing drive.

Direct coupling : If the blower is to be directly connected in the field, follow the coupling manufactur-

er's specifications for alignment and location. (SEE APPENDIX B).

ACCESSORIES

Check valve :A check valve is absolutely required when operating more than one machine on a common header toprevent back flow and gas flowing back to the inlet of the machine not in service. It might also create

a contra rotation of the machine which will eventually damage the unit.

- To be installed on the discharge side when the blower is in pressure operation.

- To be installed on the suction or discharge side for vacuum operation.

Relief valve :Absolutely required.

- For pressure operation : mount the valve on the discharge side before the isolating valve.- For Vacuum operation : mount the valve on the suction side before the check valve.- The relief valve is delivered pre-set. Valve setting should be adjusted when starting machine opera-

tion. The relief valve, as a safety device, shall be periodically checked for correct function.

Silencer :It is recommended to install a suction and a discharge silencer. The silencers should be mounted as

close as possible to the blower.

Filter :

When atmospheric air is sucked in, filters should be mounted before the blowers.For all other cases we recommend to use a suction filter.

Instrument tapping points :

Since the blower is delivered without nozzles, the required tappings will have to be provided on thesuction and discharge lines by the customer.

Flexible connectors :Flexible connectors prevent distortion from the piping and any vibrations due to sound transmission.

In general they should not be fitted directly to the machine flanges but after the silencers. In no caseshould they be used to compensate any excessive or insufficient lengths of the pipings.

NOTE : All accessories mounted before or after should be periodically checked for internal conditions,damage and oxidation to prevent any carry-over in the conveying system.

STAR-DELTA STARTING

The torque required to accelerate the rotating parts of any Rotary Positive Blower is quite small.

Blowers can be successfully started, even with the reduced torque in the Star circuit that is a charac-teristic of Star-Delta starting, providing the unit is started against zero line pressure.

If however the unit is required to start against an already pressurized line, there will be insufficienttorque available in the Star circuit to accelerate the rotating parts up to full speed and at the same time

overcome the resistance imposed by the line pressure, and the motor will trip-out.

PIPING

Inlet and discharge connections on all blowers are large enough to handle maximum volume with min-imum friction loss. The diameter of the air transmission lines should be equal to or larger than con-

nection points to minimize noise and air-friction losses. Air velocities should normally not exceed 5,000feet per minute. (1525m/mn). Excessive weight of piping and fittings can cause internal misalignmentand premature wear. Never allow the blower to carry the weight of the pipe. To prevent distortion, a

spool or sleeve-type expansion joint should be installed between the unit and the piping. Before con-

necting piping, remove any remaining anti-rust compound from blower connections. Piping must beclean. In addition, make sure it is free of dirt, scale, cuttings, weld beads, or foreign materials of anykind.

To further guard against damage to the blower, especially when an inlet filter is not used, install a sub-stantial screen of 16 mesh backed with hardware cloth at or near the inlet connections . Make

provisions to clean this screen of collected debris after a few hours operation. It should be removedwhen its usefulness has ended, as the wire will eventually deteriorate and small pieces going into the

blower may cause serious damage.

VENTILATION

Customers must assure that the blower room is properly ventilated as a large amount of heat is gen-

erated from the motor and the compression heat.

OTHERS

The above covers most of the usual equipments and accessories with standard blower installations.Other accessories, protection devices etc. are treated separately.

MAINTENANCE

LUBRICATIONOil changes:

For temperature below 65°F, run the blower for 15 minutes to warm up to oil.On every oil change, clean the drain and filling plugs and renew their sealing by means of TEFLON or

pipe sealant. (Loctite PST 56747 or equivalent)Clean the sight glasses and check oil level periodically.

First oil change should be conducted after 200 hours of operation. The following oil changes shouldbe done as per the instruction in the appendix. Oil level is correct when it reaches the middle of thesight glass. Oil level can only be checked when the machine is stopped.

FOR LUBRICATION METHOD AND QUANTITY OF APPROPRIATED LUBRICANT, PLEASEREFER TO APPENDIX (D) ATTACHED.

For low and high temperature applications SYNTHETIC OIL should be used. It is also recommendedfor lighter ranges of applications. Mineral oil can be used for medium range of operating temperature

(consult chart). The use of synthetic oil can reduce oil change frequency by 2 to 3 time .

TROUBLE SHOOTING

TROUBLE SHOOTING

No matter how well the equipment is designed and manufactured, there may be times when servicing

will be required due to normal wear, the need for readjustment, or various external causes. Wheneverequipment needs attention, the operator or repairman should be able to locate the cause and correct

the trouble quickly. The following Trouble Shooting Chart will assist the operator in these respects.Experience has shown that the most common causes of faulty operation on blower installation areclogged inlet filters, and inaccurate or broken pressure gauges, lack and/or excess of oil and grease.

Clogged inlet filters impose a restriction on the suction side of the machine which reduces the air flow,cause overheating of the unit and lost of pressure in the discharge piping. Continued running under

these conditions will lead to excise rotor expansion and will ultimately result in total seizure of the unit.The rate at which a filter element will clog depends entirely upon the environmental conditions under

which it is required to operate, and the allowable interval between cleaning can only be establishedfrom observation on site. It is essential therefore that during the first weeks of operation the cleaning

interval for filter elements should be established and then strictly adhered to .

APPENDIX '' A ''

ALIGNMENT AND TENSION OF TRANSMISSION BELTS

The alignment of the sheaves and the correct tension of the belts enable the useful life of the bearings

and the belts themselves to be utilized to the maximum. Misalignment causes asymmetric wear of thebelt and does not allow the belts of a set to be uniformly loaded. Generally, it is not worthwhile carry-

ing out regular checks on the alignment as this does not change during operation.

On the other hand, alignment must always be carried out when belts are tensioned and whenever theyare adjusted.

The external faces of the B sheaves must be on the same vertical plane when aligning and this is car-ried out by placing a straight edge as shown in Fig. A1. The face of the machine sheaves is taken as

a reference and the straight edge is placed on it, checking contact at points C and D. The motor isthen moved, keeping the 4 fixing screws only slightly loosened and adjusting screws 1,2,3 and 4 until

contact at points A and B is also made.

Any axial movements can be made by means of small knocks with a lead or rubber mallet, if the motor

size allows so, or by means of screws provided for this purpose.

A practical way of streamlining these operations is as follows :

• carry out a rapid and approximate alignment with the belts loosen ;

• make a preliminary and approximate tensioning of the belts takingcare, however, to turn the tensioning screws equally ;

• complete alignment with the necessary precision ;

• complete belt tensioning to the final value, always taking care toensure that the screws are rotated by the same mount (as, in

the final phase, parts of a revolution can be required, it isadvisable to mark the head) ;

• before fully tightening the motor adjusting screws, check the

alignment once more which, given the method followed, may require just a small

final correction by an axial shift of the motor.

APPENDIX '' A ''

Shims are only rarely needed under the motor feet to correct alignment on the horizontal plane of theaxes of the motor and machine.

Excessive belt tension may result in an unnecessary increase in the load on the bearings and thebending moment on the shaft. In extreme cases, in can even cause the shaft to break due to fatigue.

Inadequate tension on the belts causes them to slip, overheat and wear prematurely. In extremecases, overheating can cause irreversible damage to the sheaves as well. In view of the range of belts

on the market and their different characteristics, it is a good idea to have specific data so that belt ten-sion can be set correctly.

Tensioning V-Belt drives

Without exception, the most important factor in the successful operation of a V-Belt drive is proper belt-tensioning. To achieve the long, trouble-free service associated with V-Belt drives, belt tension must

be sufficient to overcome slipping under maximum peak load. This could be either at start or during

work cycle. The amount of peak load will vary depending upon the character of the driven machine ordrive system. To increase total tension, merely increase the center distance. Before attempting to ten-sion any drive it is imperative that the sheaves be properly installed and aligned. If a V-Belt slips, it is

too loose. Add to the tension by increasing the center distance. Never apply belt dressing as this willdamage the belt and cause early failure.

APPENDIX '' A ''

a) General Method

Step 1: Reduce the center distance so that the belts may be placed over the sheaves and in thegrooves without forcing them over the sides of the grooves. Arrange the belts so that

both the top and bottom spans have about the same sag. Apply tension tothe belts byincreasing the center distance until the belts are snug. See below Fig. A.2

Step 2: Operate the drive a few minutes to seat the belts in the sheaf grooves. Observe theoperation of the drive under its highest load condition (usually starting). A slight bow-ing of the loose side of the drive indicates proper tension. If the slack side remains taut

during the peak load, the drive is too tight. Excessive bowing or slippage indicates insuf-

ficent tension. If the belts squeal as the motor comes on or at some subsequent peakload, they are not tight enough to deliver the torque demanded by the drive machine.The drive should be stopped and the belts tightened.

Step 3: Check the tension on a new drive frequently during the first day by observing the slooseside span. After a few days of operation the belts will seat themselves in the sheaves

grooves and it may become necessary to readjust so that the drive again shows a slightbow in the loose side.

b) Force Deflection

This method should be used only for tensioning drives on which the grade of belt, rated belt capacity,

service factor, design horsepower, etc. are known (if the drive has been designed in strict accordancewhith the procedures, instructions and horse-power ratings).

Fig. A.2


19/55

rev 01, 15/08/98Page 4


Step 1: Install belts as per Step 1 of General Method above. Measure span length (t) in inchesas shown in Figure A.3 or calculate using formula.

Step 2: From Figure A.3 the deflection height (h) is always 1/64" per inch of span lenght (t). Forexample, a 32" span length would require a deflection of 32/64" or 1/2".

Step 3: Determine the minimum, maximum, and initial recommended pounds force using table

1 or calculate based on the required Static Strand Tension (Ts). Note: the initial recom-mended force is used only for installing new belts which have not seated themselves intothe sheaves grooves and where initial belts stretch has not taken place.

Step 4: Using a spring scale tensionner, apply a perpendicular force to any ONE of the belts at

the mid point of the span as shown in figure A.2. Compare this deflection force with thevalues found in step 3.

a. If the deflection force is below the minimum, the belts are too loose andthe tension should be increased by increasing the centre distance.

b. If the deflection force is higher than the maximum, the belts are too tightand the tension should be decreased.

When new V-Belts are installed on a drive the INITIAL tension will drop rapidly during the first few

hours. Check tension frequently during the first 24 hours of operation. Subsequent retension shouldfall between the minimum and maximum force.

To determine the deflection distance from normal position, use astraightedge or stretch a cord from sheave to sheave to usse as a refer-

ence line. On multiple-belt drives an adjacent undeflected belt can buused as a reference.

Minimum deflection force values shown in table 1 are based on assumedaverage static tensions for drives having multiple belts or on V-band, this

eliminationg calculations. (For drives using only one belt or one V-band,the deflection force must be determined by use of engineering formulas).

Find the minimum recommended deflection force for the belt section and

type based upon the small sheaves diameter, speed and drive ratio. Forintermediate sheaves diameters and/or drive ratio combinations the min-

imum deflection force may be interpolated.

Always install a complete new set

When one or two belts in a set become worn or damaged, there is a big temptation to replace only theuseless belts. The trouble is that the remaining belts have been stretched, through use, beyond their

original length. The newer, shorter belts will carry most of the load. A severe shock or load strain willeasily break these new belts. For this reason, it is always better to install a new matched set rather

than replace V belts one at a time. Used belts from a given drive can be put on a drive requiring asmaller set.

APPENDIX '' B ''

COUPLING ALIGNMENT

The correct alignment of the coupling allows the machine to operate at minimum vibration levels andprolongs the bearings life.

Alignment is carried out as follows:

• Place the axes of the two shafts coupled on the same vertical plane or on two par-

allel vertical planes, with a specified distance between them;

• Place the axes of the two shafts coupled on the same horizontal plane or on twoparallel horizontal planes, with a specified distance between them;

• Keep a specified distance between the ends of the two coupled shafts or better

between the two faces of the half couplings.

Radial mis-alignment and angular mis-alignment are shown in fig. B.1 . These can be present at the

same time.

Due to thermal expansion and other causes such as the lubricating oil film in the plain bearings, radi-al thrusts by the gears etc., the position of the two shafts coupled with the machine in normal opera-

tion can be very different from their position when the machine is off and cold. Therefore when align-ing cold, radial mis-alignment values, can be calculated so as to obtain perfect alignment when the

machine is running in normal operation.

rev 01, 15/08/98Page 2

APPENDIX '' B ''

If no specific instructions are given, the shafts must be aligned cold so as to obtain the minimum pos-sible value of radial and angular mis-aligment. The distance between the faces of the half couplings

can be taken from the drawing.

Maximum admissible mis-alignment when hot can vary depending on the type of coupling; however, ifno specific instructions are given, the following tolerances must be used:

- distance between the half coupling faces: 0.10 mm (.0035")- radial mis-alignment (T.I.R.): 0.10 mm (.0035")

- angular mis-alignment: 0.50°

The distance between the half coupling faces where there is a spacer can be measured by means of

a caliper or an internal micrometer or otherwise by a thickness gauge.

Radial misalignment can be checked by means of a setsquare or a straight bar wich is sufficiently rigid and long,

but it is preferable to use a gauge fitted as shown in fig.B.3(A). The T.I.R. reading (Total Indicator Reading) given

by the gauge for a 180°rotation represents double the actu-al misalignment. With reference to fig. B.1, half of the read-ing for a 108°rotation from 0° to 180°rotation from 90°to

270°provides the distance between the two vertical planeson wich the shaft axes are placed.

Angular misalignment can be checked by a calliper, internalmicrometer or a thickness gauge, but it is preferable to usea gauge fitted as shown in fig. B.3 (B). The ratio betweenthe T.I.R. reading (Total Indicator Reading) provide by the

gauge for a 180° rotation and the diameter of the circledescribed by the rotoation of the tracer point axis repre-

sents the tangent of the misalignment angle.

With reference to fig. B.2, from the reading for a 180° rotation from 0° to 180°, the angular mis-alignment is determinated by the height of the couplings. From the reading for a 180° rotation from

90°to 270°, the angular mis-alignment is determined by the transversal position of the couplings.

Machines and / or motors are moved laterally by means of appropriate adjustment screws provided. A

lead mallet may be needed for smaller machines without adjustment screws.

Fig. B.2


23/55

rev 01, 15/08/98Page 3


APPENDIX '' B ''

Machines and/or motors are moved vertically by using shims placed under the feet as required. When

adjusting the height of machines and/or motors with shims, the following precautions are recommend-ed :

• ensure that the feet, their bearing surfaces and every individual shim

used are as clean as possible ;

• ensure that all the anchoring screws have been tightened before

taking readings ;

• ensure that all the feet are completely in contact with the shims andthat the tightening of the anchoring screws does not produce any

deformation to the base-plate and/or the machine of motor.

A good practical method for alignment is as follows :

1. Study the machine, the height and position of which needs to be considered fixed with regard

to the base-plate.

2. Check that its anchoring screws are centered in the holes, i.e. that it is possible to moveit in all directions.

3. Completely tighten the anchoring screws.

4. Check that the height of the shaft is greater than or equal to the minimum required, cor-recting with shims if necessary.

5. Place a gauge with a magnetic base-plate on the base-plate and a tracer point on themachine feet close to one of the anchoring screws and set it to zero.

6. Loosen the anchoring screws and check that the gauge does not indicate movements of

more than 0.005 mm [.001''] (a movement greater than the given value requires the inser-tion of corrective shims).

7. Repeat the operation for all the anchoring points to the base-plate.

8. Loosen the anchoring screws of the other machine.

9. Measure the distance between the faces of the half couplings and move the machine in an

axial direction until the prescribed value is reached.

10. Tighten the adjusting screws.

APPENDIX '' B ''

11. While rotating the two half couplings at the same time measure the radial mis-alignmentand:

- move the machine transversally until the prescribed value is obtained (T.I.R. 90°- 270°);

- shim all the machine feet until the prescribed value is obtained (T.I.R. 0°- 180°);

12. While rotating the two half couplings at the same time measure the angular mis-

alignment and:

- move the machine transversally until the prescribed value is obtained (T.I.R. 90°- 270°);

- shim two of the feet of the machine until it comes within the prescribed tolerance(T.I.R. 0°- 180°).

Operations 11 and 12 affect each other reciprocally and therefore must be repeated alternately

until the correct result is obtained.

13. Repeat on this machine the operations described in items 5,6 and 7.

BLOWER CONCRETE SLAB & ANCHORING INSTRUCTION

A foundation design is very important to insure the proper installation and life of the HIBON equipment.The size of machine and package generally dictate the foundation required.

- CONCRETE SLAB

When possible pour directly on the ground with a raised portion approximately 150 mm (6") high and,at least 150 mm (6") exceeding the overall base dimensions, the surface should be leveled and smoothto mount the package directly.

- INSTALLATION ON FOUNDATIONS (CONCRETE SLAB) FOR SMALL MACHINES (Up to 60 hp)

The concrete foundation shall be solid, leveled and as smooth as possible.Before setting the machine on the foundation, the parts in contact with concrete must be cleaned of

any oil or grease traces.When installing the blower (base) on the concrete foundation, insert shims between the foundation and

the base plate if required to accommodate any uneven surface of concrete.

NEVER INSERT SHIMS BETWEEN THE BLOWER AND BASE PLATE TO CORRECT ANY LEV-ELING DEFECTS.

Max. horizontal deviation is 0.2 mm/m (.010"/ft).Drill a hole in the concrete foundation from the size of Hilti anchor bolts selected, insert Hilti in place,

then tighten the anchor bolts firmly. The same procedure is to be followed when the blower base ismounted with elastic supports. See fig. C.1 and C.2 .

1. Insert the elastic pads under the base plate and bolt to the base plate.2. Drill holes in the concrete.3. Hilti (anchor bolts) to be tightened firmly.

APPENDIX '' C ''

- INSTALLATION ON AN ISOLATED CONCRETE FOUNDATION(Generally recommended for medium (25 HP to 125 HP) and large (150 HP and up) size machines).This type of foundation isolates the machine from the rest of the foundation and reduces vibration

transmission to the structure and other equipment.The mass should if possible be equivalent to 1.5 times the weight of the equipment. 1/2" (12 mm)

cork is generally used as isolation and the surfaces are left rough for grouting purposes.The use of anchor bolts, commonly used for machinery with relatively high installed power, involves

the use of a concrete foundation isolated from the rest of the building to prevent the transmission ofvibration.

Where anchor bolts are used, the base- plate shall be fitted in accordance with the following instruc-tion:

* The concrete foundation, if possible, should be made to be isolated from the rest of the building.

The surfaces shall be left rought so as to provide a better adhesion for grouting (which is carriedout subsequently).

* Lower the base-plate to approximately 200 mm (8") from the plinth, centering the machine.

Position the 100 X 100 X 20 mm (4 X 4 X 7/ 8") plates under the leveling screws.

Lower until the leveling screws come in contact with the plates. Position the base-plate in its final loca-tion, longitudinally and transversally. Centre the plates under the leveling screws. Wedge the plates

which are not in contact with the adjustment screws.

* Check that the base-plate is level by using a spirit level sensitive to 0.1 mm/m (.005"/y). This

check shall be made longitudinally and transversally on all finished surfaces. It shall be level 0.1mm/m (.005"/y). It is adjusted by using the spirit level on the finished surface as shown in

fig. C.3 and using the leveling screw. Each leveling screw can be used to raise or lower thebase-plate and therefore the edge of the finished surface relative to adjacent one.

* All surfaces are to be leveled transversally and longitudinally as specified.* Clean the surfaces of the plinth and prepare it for grouting. Provide an enclosure as shown infig. C.3 . If it is being installed in the open air, provide proper drainage for rainwater, taking

account of the base-plate share. Pour grout under the base to the level indicated in fig. C.3 .Avoid the use of mechanical vibrators so as not to disturb the level surface obtained. Instead,

promote grout with the use of bars or chains.* Cure the grout adequately for an appropriate number of days.

* Drill the holes as per the anchor bolt manufacturer's recommendation. Install the anchor bolts,generally "Hilti chemical type", when the equipment is settled. Loosen the leveling screws.

* Tighten all the anchor bolt nuts and the associated lock nuts before fitting the machines.

• Size or anchor bolts and leveling screws are

indicated on the general arrangementdrawing.

LUBRICATION

NOTE: Depending upon the installation position, oil filling and draining plugs as well as sight glasses

shall be positioned in the proper location.

WARNING: Units are normally shipped without lubricating oil.

Do not operate before lubricating.Note: See parts lists identification number

Timing gears (023) and bearings (019) are lubricated by a simple but effective splash system. At thegear end, gear teeth are lubricated by being partially submerged. The gear teeth serve as oil slinger

for the gear end bearings (019). The drive side bearings are permanent factory lubricated.

FILLING PROCEDURE: Remove fill plugs (B) from top of gear end headplate. Using the grade oflubricant recommended, fill gear end until oil reaches midpoint in sight glass (D). Do not overfill.Always maintain oil level within sight in the glasses (544), this should be checked when the machine

is not operating. The drive side bearings are permanent factory lubricated. If bearings are removedthe bearings shall be lubricated with grease MOBIL TEMP SHC 100 or equivalent. Oil should be

changed every 2000 hours under normal service, or more frequently if inspection indicates it is nec-essary.

The oil drain plug is located under gears headplate(E).

LUBRICATION


NOTE: See parts lists indentification number

Timing gears (9-10) and bearings (18-19-20) are lubricated by a simple but effective splash system.At the drive end, oil is distributed by an oil slinger (14) attached to the drive shaft (3). At the gear end,

gear teeth are lubricated by being partially submerged. The gear teeth serve as oil slingers for the gearend bearings.

FILLING PROCEDURE: Remove fill plugs (A) from top of each casing. Using the grade of lubricantrecommended, fill both end until oil reaches midpoint in sight glass (C). Do not overfill. Replace fill

plugs. Always maintain oil level within sight in the glasses (C), this should be checked when themachine is not operating. Oil should be changed every 2000 hours under normal service, or more fre-

quently if inspection indicates it is necessary.The oil drain plug is located under each headplate. (B)

LUBRICATION

WARNING: Units are normally shipped without lubricating oil.

Do not operate before lubricating.

FILLING PROCEDURE:Remove plug A from top of each headplate. using the grade of lubricant recommended (synthetic oil is

preffered) file dive end and until oil reaches mid point in sight glass.

IMPORTANT NOTE FOR TRUCK INSTALLATION:

Blower may be installed at an angle for instance (to match the angle of truck transmission) or in case

the truck is not parked on a leveled surface, please observe the following procedure:

• Check the oil or both sides of each oil casing (drive and driven side). Properoil level shall be the middle of the sight glass on either side of the blower.

• If the oil level is low on one side, correct oil level to middle of sight glass asrequired.

• As same machines with high shaft, there is only one sight glass on the driveend oil casing. In this particular instance only, fill the sight glass up to the top

as shown below:

• Maximum operating angle of blower is 15°.

DO NOT OVERFILL

Replace sealant on fill plugs (use LOCTITE PST56747 or equivalent). Oil shall be changed every 1000hours (high service) or 2000 hours (industrial use) or every 6 months. Oil may be changed more fre-

quently, if inspection indicates it is necessary. The oil drain plug is located under each oil casing.
