1.1 COMPRESSOR tJESCRIPTION

The CENTAC is a two stage high efficiency centrifugal compressor constructed with acast iron vertically split casing assembiy which consists of casing and a casing cover.This bolted and pinned assembly is only opened for servicing of the bullgear and bullgearbearings. The gearcase cover contains separate removable pinion bearing covers.Access through these covers provides means for inspection of the bullgear and pinionteeth, thrust bearing inspection and for removal and setting of impeller/diffuser runningclearances. The single forging helical bullgear runs on two oil lubricated bearings anddrives the two rotor assemblies.

Each precision balanced rotor assembly consists of a helical geared pinion shaft, a highefficiency stainless steel open impeller and a removable thrust collar. The impeller andthrust collar are each secured to the shaft using a precision polygon attachment. Theseparts are then retained by bolts.

Each stage is provided with a plain bearing assembly, thrust bearing assembly, and shaftseal assembly. The pinion plain bearing assemblies are precision machined, fixedgeometry, journal bearings with one piece steel backed babbitt which are pressure fedwith lubricating oil. The bearings are designed for maximum operating stability, loadcapacity, and low friction loss. The pinion thrust bearings combine a similar journalbearing with a tapered land thrust bearing. A thrust button or bearing is used in theinactive direction.

/'The pinion shaft seal assemblies are of the cartridge type. They are mounted in theplain bearing housing behind the impeller. Each cartridge consists of three one piecefully floating noncontact carbon rings. One ring is used as an air seal, two as an oilseal. Seal air is injected between the two oil seal rings to insure that oil is not drawnpa~t•.!~ ~~.~I~~~~!-!!i!1\LoJI .•.fr~.l!.cgmpr~l:lsiorl~.~'Y~rt! !R.atrng~p!:jffi"~:Is ..P!o"icreaDetweerr·ine air and QiLseals......···················,._'A<".=W_""' ~?

The diffuser is cast iron with pinned on stainless steel vanes. It is located betweeneach impeller and cooler. And, it is designed for maximum efficiency while maintainingsmall physical size keeping the compressor compact and easily serviceable.

A noncontacting vibration probe is located next to each plain bearing to providemeasurement of the radial vibration of the rotor assemblies.

The high efficiency cartridge intercooler and aftercooler are donut type with multipasswater flow over the tubes. The tubes are internally finned and air passes through thefinned tubes. This arrangement results in high heat transfer efficiency.

1.0 MACHINE DESCRIPTION

The fabricated steel baseplate with integral lube oil reservoir coated to r~list corrosion,supports the compressor casing, lube system, and control panel and has provisions forfoundation bolts.

1.2 LUBRICATION

The lubrication system for the compressor is completely self-contained and mounted onthe baseplate.

Oil is drawn from the oil reservoir located in the baseplate and passes through the oilpump. Two oil pumps are provided: a prelube pump and a main oil pump.

The prelube oil pump, driven by an electric motor, serves to prime the main oil pump andflood the compressor bearings and oil lines before the compressor starts. The prelubepump is not intended to function as an auxiliary oil pump to backup the main oil pump.

The prelube oil pump starts when the control panel is energized and runs until thecompressor is up to speed and the main oil pump increases oil pressure. The prelubepump is shutdown automatically by a timer which starts timing when compressor isstarted and stops the pump after the delay required to allow the compressor to come upto full speed. When the unit trips on the shudown cycle, the prelube pump will startimmediately and will continue to run until the panel is de-energized. After thecompressor shuts down, the prelube pump should be allowed to run 20 to 30 minutes tocool down the compressor bearings.

';Aseal air pressure switch interlock prevents the prelube pump from operating if seal air'I. .""{pressure is not established.

The main oil pump is an oversized positive displacement type pump driven by the mainshaft. The main pump discharge pressure is controlled by a relief downstream of the oilcooler and filter. /n the event of a main driver or power failure, the main oil pump willcontinue to supply oil to the bearings and gears during coast down.

The oil pumps are equipped with an inlet strainer for protection against foreign particles.Check valves in the discharge line of the prelube pump and on the inlet of the mainpump are provided to prevent reverse flow through the pumps.

Oil passes through the oil pump to the oil cooler which is a shell and tube type cooler.Enough water has to flow through the oil cooler to maintain normal oil operatingtem perature to the compressor bearings.

An oil temperature control 3-way mixing valve automatically regulates proper oiltemperature to the bearings by mixing hot and cold oil.

1-3

1.0 MACHINE DESCRIPTIONINGERSOlL-RAf\I).AIR COMPRESSORS

The oil flows to the oil filter from the oil cooler. The oil filter supplied is a 10 microntreated paper element type filter

Oil passes from the oil filter to ·the compressor bullgear and pmlon bearings with aportion of the oil being bypassed through a relief valve to the reservoir. This valveallows the input pressure to the compressor to be raised or lowered by adjusting thevalve setting. The remainder of the oil passes through the compressor and drains intothe reservoir.

Low oil pressure protection is provided by a pressure sensing device which will trip theunit and light the alarm light.

Abnormal oil temperature protection is provided by a temperature sensing device set totrip the unit and light the alarm light. The same device acts as an interlock to preventthe unit from being started if oil temperature is below the minimum.

An oil reservoir heater is furnished to insure adequate oil temperature for compressorstart-up.

The lube oil reservoir has provisions for a lube oil drain with plug. A gate valve may beinstalled to facilitate changing oil.

All the necessary instruments and safety devices are included in the oil system· toprotect the compressor.

1.3 CONTROL SYSTEM

The control system includes all devices necessary for starting and stopping the com­pressor, controlling system pressure, and assuring safe operation with respect tolubrication, vibration and temperature. The basic control system is designed forconstant pressure operation. The control system also includes a surge sensing devicewhich protects the compressor from sustained operation in the unstable surge region. Ifthe surge sensor detects compressor surge, it automatically unloads the unit.

The complete control system is pre-assembled and requires only the connection ofelectrical power and dry instrument quality air of 80-120 PSIG.

The compressor is operated by the two methods of control described below.

MODULATE CONTROL

Modulate type of control maintains the customer's system pressure at a constant value,which is accomplished by throttling the inlet valve within the compressor's throttlerange. If system flow demand is less than the minimum throttled capacity, constant

1-4

1.0 MACHINE DESCRIPTION1NGEFlSOll-BAND.AIR COf.oI ReSSORS

discharge pressure is maintained by leaving the throttled inlet valve at the minimumthrottled capacity and throttling the bypass valve. Throttling the bypass valve providescapacity control from the minimum throttled capacity to 2ero capacity requirements.

When the compressor is operated unloaded, the bypass valve is fully open and the inletvalve is held partially open by a signal from the Controller. The small amount of air thatpasses through the compressor while in the unload mode is to maintainstabiJity andprevent overheating.

The compressor is at full capacity when the inlet valve is fully open and the bypassvalve is fully closed.

As flow demand decreases, constant discharge pressure is maintained by reducing theflow delivery to the system by throttling the inlet valve and keeping the bypass valvefully closed.

As flow delivery is reduced and the maximum inlet throttle range is reached, thecompressor approaches its surge point. any further reduction in compressor capacitywould cause the unit to become unstable and operate within this surge region. Toprevent the compressor from operating within this region, the inlet valve is held open bythe control signal at the maximum inlet throttle point.

As system flow requirements continue to decrease below the inlet throttle range of thecompressor, the compressor will continue to follow these demands by blowing offsurplus air through the bypass valve.

AUTO-DUAL CONTROL

Auto-dual control functions the same as modulate control, but has an additional"Modulate + Two-Step" control mode. Selection between modulate and modulate +two-step can be made at the control panel.

When capacity requirements are within the throttle range of the compressor, thecompressor cooperates efficiently by automatically throttling the inlet valve to maintainconstant pressure. If capacity requirements decrease below the maximum throttlerange, the compressor will unload. When system pressure decreases to a preset cut-inpressure, the compressor will go to full load. The compressor will increase dischargepressure to the constant pressure setting, and will respond to the demand requirementsof the system by remaining at full load or throttling and then unloading.

4.0 INSTALLATION

4.1 GENERAL

Proper installation is the most important prerequisite for satisfactory operation of high·speed rotating machinery. Proper" support ofthe machinery is required to give maximumreliability at minimum operating cost.

The proper design of a foundation and piping arrangement requires an intimateknowledge of local conditions. The user must assume full responsibility for an adequatefoundation. It is recommended that it be designed by someone who has experiencewith machinery foundations.

See provided certified General Arrangement drawing (Section 10.0J forcompressor/customer connection details.

4.2 LIFTING

The completely assembled compressor is designed for lifting by a fork lift truck or otherequivalent means by using the 2 openings provided at the baseplate.

4.3 PLANT LAYOUT

A well designed installation will result in lower installation and operating costs.Operation and maintenance personnel will generally give better attention to acompressor which has been installed with good planning for the various needs.

The location of a packaged centrifugal compressor within a plant facility is veryimportant. The compressor should be located in an area accessible to operators andmaintenance personnel, and should be in a climate controlled environment (heatedbuilding).

Machinery can best be handled with overhead crane facilities for installation. Anoverhead rail with a chain hoist will simplify the removal of the largest component parts,if and when it becomes necessary to inspect or replace them.

Ample space should be provided to permit easy handling during installation. Floor spaceshould be provided (three foot aisle around the unit) where parts of the compressor maybe placed during periodic inspection of the rotating elements and internal parts. Makeprovisions for clearance limitations specified on the General Arrangement Drawing.

Machinery should be installed where it is easily accessible for observation andmaintenance. In elevated locations or in pits, there should be stairways, catwalks, etc.

Ventilation around the unit is important. On motor driven units the heat radiated to theair in the room will be approximately six (6) percent of the total horsepower (1 HP =42.4BTU/MIN)'

In areas where noise could be a problem, steps should be taken in treating hardreflective surfaces in the area. Avoid installing the unit in an area with low hard ceilingsand walls.

The unit should not be installed in a damp or dusty atmosphere or where corrosivevapors may enter the compressor or the driver.

4-2

4.0 INSTALLATION

4.4 FOUNDATION

The foundation need not be massive but should be sufficient to provide support for theunit. .

Since there are no out of balance forces such as reciprocating or shock loads, all loadson the foundation may be considered as static loads. If the unit is to be Ibcated in anarea with other machinery, it is essential that vibrations are not transmitted to the unit.

For the CENTAC compressor package, a simple concrete pad or steel support structureis recommended for each compressor. It is recommended that the concrete pad be leveland flat so that the bottom of baseplate is in full contact with the pad. Anchor bolts areto be used to hold the compressor in place. No grouting is required.

4.5 LEVELING

The CENTAC should be leveled at the time of installation. To level the unit, place itover the anchor bolts with the baseplate beams resting on steel wedges or shims, ifnecessary. Leveling should be within 0.1 inches/foot.

4.0 INSTALLATION

NOTETHE INFORMATION PRESENTED IN THISMANUAL IS REPRESENTATIVE. IT SHOULDBE USED FOR' PRELIMINARY PLANNING PUR­POSES ONLY. SEE CERTIFIED DRAWINGSFOR APPLICABLE TO SPECIFIC UNITS.

4.7 INLET AIR FILTER

Normally, the inlet filter/silencer is mounted on the inlet pIpIng supplied with thecompressor. (Units 2300 CFM (65 Cu. M./Min) and larger have filters that are mountedremote and piped to the compressor.)

Routine inspection of the filter is recommended and the addition of instrumentation toindicate pressure drop across the filter elements is also suggested. When this dropincreases substantially the elements should be cleaned or replaced.

If the inlet air filter is mounted at a remote location, it should be a high efficiency unitdesigned to remove 98 % of all particles at 4 microns. For adverse environmentalconditions a more efficient inlet air filter is recommended.

The inlet filter is normally oversized to increase the time between elements changes andreduce the velocity through the filter to give a lower noise level.

The filter should be as close as possible to the unit to minimize pressure drop. Accessto the filter should be provided with ample room around the filter for maintenance. Apermanent platform should always be built around elevated filters to provide safety forpersonnel assigned to changing filter elements.

4.8 INLET AIR PIPING

Inlet air is the life line of any air compressor. It is imperative that the compressorreceive clean filtered air to function correctly with low maintenance. A well thought outinlet piping design will save many hours and dollars in maintenance.

Normally, the air inlet piping is supplied with the compressor. This piping must beinspected for cleanliness by an I-R Service Supervisor prior to start-up.

REMOTE FILTERS

When the filter is mounted at a remote location with the inlet air piping being suppliedby others, the recommendations below should be followed.

4-5

4.0 INSTALLATION

NOTETHE DESIGN OF THE PIPING SYSTEM IS THERESPONSIBILITY OF THE CUSTOMER. DATAAND COMMEillTS ARE 'OFFERED AS AN AIDTO INSURE A SUCCESSFUL !NSTALLATIONBUT INGERSOLL-RAND CANNOT ASSUMERESPONSIBILITY FOR DESIGN. WERECOMMEND THE CUSTOMER CONSULT ASPECIALIST SKILLED IN THE DESIGN OFPIPING TO SUPPLEMENT AND INTERPRETTHE FOLLOWING INFORMATION ANDENSURE A SUCCESSFUL INSTALLATION.

The inlet piping from the inlet filter to the compressor must be clean and made of a non­rusting material such as stainless steel, aluminum or suitably coated steel pipe. Thispipe should be sized to minimize pressure drop. The inlet pipe should be suitably flangedso that it may be cleaned in sections. Transitions in pipe diameters should be gradual.

Inlet piping should be short and direct, with the combined filter and piping pressure dropnot exceeding 0.3 PSI. The minimum inlet pipe diameter must be per the table inSection 4.6, with reduction at the compressor flange. Long radius elbows should beused.

Any horizontal run of pipe should be installed so that condensation in the piping will runaway from the compressor and form a low point with drain valve to remove themoisture.

The piping must be installed and supported to avoid strains on the casing.Misalignment, which is a frequent cause of vibration, can very often be traced directlyto piping strains.

Three sources of piping strains are:

1. Dead weight of the piping itself.2. Expansion or contraction of piping as it undergoes temperature change.3. Pressure within the piping.

NOTETHE COMPRESSOR IS NOT AN ANCHORPOINT FOR THE SYSTEM PIPING.

Adequate piping supports are necessary to prevent excessive dead loads on the flangesof rotating machinery. They should normally be of the flexible type and located asclosely as possible to the flange connections on the machinery.

4-6

4.0 INSTALLATIONINGERSOLL-RAND.,AIR COMPRESSORS

On all models it is advisable to install spool pieces that will allow the casing sections tobe removed and the piping to be out of the way of personnel for maintenance. The inletpipe will be removed for inspection at start-up.

The importance of always operating' the compressor with clean air inlet piping must bestressed. No compressor will accept the injection of foreign material into the operatingcomponents without possible damage or loss of performance.

4.9 AIR DISCHARGE PIPING

The discharge pipe must meet the minimum requirements with regard to size,temperature and pressure ratings. Where pipe diameter conversion is necessary, thetransition should be gradual. The use of long radius elbows are recommended andpiping may be sized by normal methods.

For the best performance, a straight run of pipe approximately three (3) pipe diameterslong should be interposed between the discharge check valve and a long radius elbow toallow for smooth operation of the check valve.

On all compressors it is necessary to install a spool piece that will allow the casingsections to be removed and piping to be out of the way of maintenance personnel.

A block valve should be installed in the discharge line ~o isolate the unit formaintenance. A safety valve should also be installed between the block valve and thecompressor to prevent over pressurizing the system.

Drain valves should be installed in piping low points to remove condensation whichmight form during periods of shutdown. Piping should be designed so that condensationwill not drain back to the compressor.

Adequate piping support is needed to prevent excessive dead loads on the compressorflange. Provisions should be made in the discharge piping whereby all alignment may bemade in the piping and not the compressor.

4.10 EXPANSION JOINTS

With proper piping layout and installation, expansion joints may not be required.

4.11 CONTROLLED AIRIINSTRUMENT AIR PIPING

The controlled air line supplies a controlled air signal from the compressor discharge lineto the control panel. The- controlled air source should be located in an area of lowturbulence, between the check valve and the bloc!> valve. Normally 10 pipe diametersafter the check valve is sufficient. If the control line is to be installed in the horizontalrun of pipe it should be attached to the top of the pipe. The controlled air Iirie should berouted to the control panel in such a manner that this line will not have to bedisconnected in order to perform maintenance on the compressor. The controlled airline should be connected to the control panel bulkhead fitting marked "PT-1" (or "CAMfor some panels). This connection is a 1/2 inch FNPT line reduced to 1/4 inch tubefitting.

The controlled air piping should be nonferrous material such as stainless steel,aluminum. or copper pipe to prevent rusting and scaling.

Instrument air piping supplies seal buffer air and the motive pneumatic power air to thecontrol valves. The air used must be cleen dry instrument quality air. For best resultspiping should be connected to a refrigerated air drier and filter prior to connection on theunit. The CENTAC normally requires air at 80-120 PSIG.

The final filtering medium should be sized for a flow of a minimum of 10 CFM with thefilter located close to the panel. An isolating valve may be located ahead of the filter.

The instrument air line is connected to the control panel bulkhead fitting marked "IA' bya 1/2 inch FNPT. Piping should be noncorrosive, copper or stainless steel. Separatelines should be used for "PT-1" and "IA·.

4.12 AIR BYPASS PIPING

Normally. the bypass piping is provided with the compressor to recirculate the bypassair back to the inlet silencer. If the compressor does not have an aftercooler (hot airdischarge), bypass recirculation to inlet is not possible. Therefore the bypass must bevented to the atmosphere. In this case a silencer is required and should be installed perthe following recommendations. A suitable silencer is offered as an optional extra tothe compressor package. Consult the certified drawing for complete technical details ofthe silencer. Bypass piping shall be two (2) inches to the silencer. (Units 2600 CFM(73 Cu.M./Min.) and larger do not have bypass recirculation and require sHencers.)

The silencer is usually installed close to the compressor with the vent piped outside; oralternately, the silencer may be installed outside the building. Piping from the silencershall be five (5) inches in diameter.

NOTICEEXTERNAL COMPRESSOR PIPING

nAil air and water inlet, and air and water discharge pipework to andfrom the inlet and discharge port connections must take into accountvibration, pulsations, temperature, maximum pressure applied, corrosionand chemical resistance. In addition, it should also be noted that

-lubricated compressors will discharge some oil into the air stream;therefore, compatibility between discharge piping, system accessories,and software must be assured. Where compatibility questions exist,contact your nearest Ingersoll-Rand Office. n

HFor the foregoing reasons, the use of plastic piping, soldered copperfittings, and rubber hose as discharge piping is not recommended. Inaddition, flexible joints and/or flex lines can only be considered for suchpurposes if their specifications fit the operating parameters of thesystem. Failure to adhere to these recommendations can result inmechanical failure, property damage and serious injury or death. n

n It is the responsibility of the installer and owner to provide theappropriate service pipework to and from the machine.n

NOTICE

On receiving the Centac, be sure to inspect the unit for evidence ofdamage during shipment immediately notifying the carrier and thenearest I-R Representative if any damage is noted.

The compressor should be stored on a level floor or supports, in a dryprotected area. Based on these conditions, the Centac has beenprepared for 120 days storage in domestic shipments. If the unit is tobe stored for periods longer than 120 days it will require additionalprotection.

Please contact the nearest I-R Representative prior to shipment forinstructions on extended storage and advise him of the proposed periodof storage.

To reduce maintenance time, the bypass pipinrminimum amount of pipe must be removed duril

To prevent rain and snow from entering the byrturned down or have a short horizontal run ofpiping, install a drain in the lowest part.

4.13 WATER SYSTEM PIPING

Water piping covers cooling, drain. and air vent piping. These systems cover coolingwater to the air and oil coolers of the compressor. a means of removing condensatefrom the moisture removal sections, and the connection of air vents and cooler drains.

Water used for cooling should be clean and free of corrosive elements. Since purewater may not be practical, it is necessary that the water used be treated and filtered tofall within the following range. The total hardness as CaC03 should be less than 100PPM. The acidity should be within the 6.0 pH to 8.5 pH range. The suspended solidsshould not exceed 50 PPM. The langelier saturation index should be between +0.5 and+1.0.

A water manifold to the air and oil coolers is provided on the compressor with singleinlet and outlet connections for customer hook up.

A throttle valve is recommended on the discharge line of the manifold to control thewater flow and ensure that the coolers operate full of water.

Gate valves may be fitted at the inlet and discharge of the water manifold system toallow isolation of the compressor when necessary.

A water flow switch is installed in the water manifold for indication of no water flow.

Air cooler vents with valves are provided at the highest point in the air cooler casings.They are supplied to insure that the coolers are full of water when the compressor isoperating and so that air pockets cannot form in the coolers. If part of the cooler isstarved for water, over-heating may occur resulting in damage. Therefore, vents shouldbe held open at all times.

These connections must be piped to drain, or suitable connected to the compressorwater discharge manifold with visual indication of water flow through these vent lines.

When a closed cooling water system is utilized, casing vents should be piped to thelower pressure discharge water line with visual indication to insure· flow through thevent piping.

4.14 CONDENSATE DRAIN PIPING

Air entering the first stage of the unit carries with it a certain amount of moisture. Theamount of moisture depends on the"temperature and relative humidity. The maximumamount occurs on days of high temperature and high relative humidity.

Moisture is removed from the air as it passes through each stage of compression. Asthe air passes through the coolers, water vapor in the air is condensed and collected inthe moisture separator. This condensation is removed by condensate traps to preventwater carryover into the next stage of compression. Excessive water carryover maycreate problems.

Condensate traps with bypass valves for each stage are factory installed. Trapdischarges should be open to a trough or drain which will allow a visual check of theindividual trap function.

Regular trap maintenance is recommended to prevent clogging, which could result inwater carryover inside the compressor.
