CHAPTER I

GENERAL INFORMATION 1-1 INSTRUCTION COAIRE screw air compressor unit is a complete package type driven by an electric motor It is single stage oil injected rotary screw type with all components full piped wired and mounted on a common base it is a very self-contained air compressor package

1-2 SCREW COMPRESSION PROCESS

1-2-1 SUCTION PROCESS Along with the rotation of the rotor air is admitted fully into the void of two rotors through the suction port The void is then isolated from the suction port with the casing wall thereby completing the suction process

Fig 1-1 Suction Process

1-2-2 COMPRESSION PROCESS The air in the void is compressed as the male rotor lobe meshes between the female rotor lobes and squeezes the air against discharge cover

Fig 1-2 Compression Process

1-2-3 OIL INJECTION PROCESS As pressure builds oil is injected into the compression area and onto the bearings and shaft seal serving to lubricate absorb compression heat and seal the rotors

Fig 1-3 Oil Injection Process

1-2-4 DISCHARGE PROCESS Compression continues as the rotor rotates When the void comes to the discharge port provided in the discharge chamber the compressed air is discharged through the port While this process is occurring with one inter-lobe space the other spaces are following the same cycle Therefore air is compressed continuously

Fig 1-4 Discharge Process

2

1-3 COMPRESSED AIR FLOW The panel has an intake duct through which air is drawn into the enclosure Airflows through an air intake filter intake silencer and suction control valve to the air-end suction port Air then is compressed by the rotation of the male rotor and oil is injected into the air-end during compression process The injected oil performs various functions such as sealing cooling as well as lubricating The airoil mixture leaves the air-end through the discharge port and flows into the oil separator where the oil is separated from the compressed air Compressed air leaves the oil separator and is supplied to discharge connection of the unit via minimum pressure valve after-cooler and liquid separator

1-4 COOLING AIR FLOW The air-cooled unit comprises a forced ventilation system with a cooling fan which is driven by an electric motor First the cooling air removes the heat generated from the main motor air end etc The cooling air is then forced into the oil and after-cooler by cooling fan After the heat exchange the hot air flows through the ventilation duct and is exhausted from the ventilation louvers in the panel

1-5 OIL SEPARATION Primary separation Most of the oil is separated from air by the impact at the inner wall of the oil separator and by the fluid cyclonic effect After primary separation the heavy oil falls and is collected in the oil sump at the bottom of the oil separator Secondary separation The air which still contains fine oil particles flows through the oil separator element where the oil forms into large particles and is collected at the bottom of the element shell Then clean air leaves the oil separator 1-6 OIL FLOW The oil which is collected in the oil sump at the bottom of the oil separator is circulated through the lubrication system by the pressure differential existing between the oil separator and the air-end The oil temperature control valve is a bypass valve When the oil is cold the oil bypasses the oil cooler partly or completely and is sent to the oil filter When the oil is hot 185 lsquoF(85rsquoC) or more the oil flows into the oil cooler unless by-pass the compression chamber and lubrication parts of the air-end Oil injected via the internal oil hole is provided into the intermesh among male rotor female rotor and the rotor casing the shaft seal suction side and discharge side bearings 1-7 OIL SCAVENGE FLOW After oil is separated from the air and collected in the element shell of the oil separator it is scavenged to the compression chamber of the air-end by the internal pressure differential so that the oil carry-over in the discharged air can be controlled within the allowable limit

1-9-3 PIPING WORK

CAUTION

- All service piping must be installed so as to exert zero force of movement on the system

- A drain valve and isolation valve should be mounted near the compressor discharge section

- Water condensation can affect the operation of pneumatic devices After-coolers and the addition of

air dryers can eliminate this hazard Similarly avoid allowing compressor coolant to enter the plant air

systems Air line separators properly selected and installed will reduce any liquid carry-over

- When installed in parallel operation you must provide an isolation valve and drain trap for each

compressor unit before the common receiver Screw air compressors should not be installed in air

systems with reciprocating compressors without a means of isolation such as a common receiver It

is recommend that both types of compressor units are piped to a common receiver utilizing individual

air lines

- In case of a lead fluctuation or a very small volume in pipe from discharge connection of compressor

unit to the end of the piping the use of air receiver is recommended

- In case the discharge piping has to be unusually long you should select the diameter of the piping in

considering the pressure drop in the piping

- Consult your distributor for proper technical support

Fig 1-9 Parallel installation Fig 1-10 Installation with reciprocating compressor

FUNCTIONAL DESCRIPTIONS

3-1 COMPRESSOR AIREND Oil injected single stage rotary screw type that primarily consists of rotors housing and shaft seal along with other component parts Features Precision grind rotors provide close inter-lobe clearance This minimizes leakage and increases efficiency

Long service life and high reliability of bearings achieved by application of 5+7 profile rotors At the discharge end of the compressor angular contact ball bearings for the male and female rotors are located to support axial thrust loads and to position the rotor Cylindrical roller bearings are also located to support radial loads

With a differential pressure lubrication system the compress or can dispense with an oil pump thus dramatically simplifying the oil supply system

The wedge construction of the secondary sealing element of the mechanical seal naturally eliminates leakage This seal is highly reliable and excellent performance

3-1-1 ROTORS The male rotor has five lobes and the female rotor has seven grooves This is patented SRM designed profiles

sludge deposits in the system resulting in severe damage or breakdown of the unit The major causes of such deposits are Mixing of different types or brands of oil Use of unsuitable oil Failure to drain the condensation which will result in oil deterioration Failure to change oil within a scheduled maintenance interval

WARNING

Use of inappropriate oil andor improper maintenance may result in catastrophic damage to the air

compressor or may result in a oil separator element fire

CONSULT YOUR DISTRIBUTOR FOR MAINTENANCE SERVICE AND COLUBE 68 COMPRESSOR OIL

4-2-1 FUNCTIONS OF OIL Oil is an essential factor in the oil flooded rotary screw compressor Use COAIRE COLUBE 68 only which is developed for pressurized circulation system containing rust foam oxidation and wear inhibitors along with effective water release characteristics Oil performs the following functions Lubrication Oil lubricates the bearing and other internal components Sealing Oil seals the clearance between the two rotors and clearance between the rotors and inner wall

of casing This prevents air leakage above the inter mesh during compression to increase compression process efficiency

Cooling Oil is injected during compression process to remove the heat of compression

WARNING

Never mix different brands or types of oils each other Blending of oils may cause a formation of varnish

or sludge deposits in the system If oils have been carelessly mixed or if a certain brand of oil must be

replaced with another be sure to flush out the oil system first Consult your distributor for the

procedures We highly recommended the use of Genuine COAIRE Screw Compressor Oil

COAIRE-COLUBE 68

4-2-2 OIL CHANGE A practical way is to change the oil at the following intervals

First oil change 500 hours after initial start -up Second oil change 1500 hours after the first oil change( 2000 hours after the initial start-up) Third and consequent oil changes Every 3000 hours after the previous oil change Oil life is related to working environment High operating temperature or dirty ambient conditions will

require more frequent oil changes The above intervals are based on normal operating conditions If condensation is not drained from the unit the

oil will be deteriorated and required more frequent oil changes Proceed as follows

Run the unit loaded mode long enough to have the oil warm up Stop the unit confirm that the pressure has been released completely and close the isolation stop valve at

the discharge outlet and disconnect the main electrical Place a drain pan unde r the oil drain valve of the unit and open the valve Open the plug of oil filling port

on oil separator to speed up draining For draining the oil cooler remove the plug at the drain outlet of the oil cooler to let the oil run down Drain the oil as completely as possible Then close the drain valve of the oil separator and drain plug of oil cooler Return the plug to the drain outlet and tighten

Fill with new oil through the oil filling port of oil separator Refer to the specification table for appropriate oil amount

23

After securely tightening the plug at the oil filling port run the unit to make sure there are no oil leaks

4-2-3 DRAINING CONDENSATION Moisture contained in intake air can be condensed into water during long unloading time or when the unit is stopped and this moisture is accumulates in the separator sump Since the water in a compressor system can cause deterioration of oil and internal rusting do not neglect draining the condensation at least on a daily basis Draining should be performed before start-up since oil and condensation have been sufficiently separated from each other Open the drain valve at outlet of oil separator sump Use a pan to store the condensation being drained Closely watch the draining condensation and close the valve

NOTE

If a compressor operation can be suspended (for example during lunchtime) it is a wise practice to

drain the condensate once again after the suspension time Thirty(30) minutes may be enough for

sufficient separation of oil from condensation

WARNING

Even if the unit is in 24 hour continuous service it is still recommended to perform a draining

procedure Normally in such an operation mode an extra stand-by compressor has to be installed at

the same time to allow for better draining of condensation

CAUTION

LUBRICANT

Avoid prolonged breathing of vapors Always use adequate ventilation contact with eyes should be

avoided Avoid prolonged periods of skin contact

If excessive vapors are inhaled remove person to fresh air area In the event of contact with eyes

flush with water and consult a physician if serious irritation persists

In the event of contact with skin wash contacted area with soap and water Wash clothing before

reusing

Oil is flammable Use water fog foam dry chemical or carbon dioxide to extinguish Avoid use of

direct stream of water since the oil may float and re-ignite

Dispose of oil by using an recycling service Do not dump oil into drain or onto the ground Do not

place oil or partially filled oil containers in trash Keep out of sewers and water systems
