Refrigeration Compressor

 
CHINTAMANI CH SERIES
 
HEAVY DUTY Refrigeration COMPRESSOR
CH1, CH2, CH3, CH4, CH6, CH21, CH31, CH42, CH51
 
   
SALIENT FEATURES OF CONSTRUCTION
 
1. Welded Steel Crankcase : Low in weight Gas tight and impact proof Smooth internal surfaces guarantee good oil condition.
2. Water Cooled Cylinder Block : This crankcase has in built water cooling jacket for cylinder head to avoid over heating of piston and liner element leading to trouble free long life of compressor
3. Silent Oil Pump : Internal gear pump is provided with special self aligning driving plate to reduce vibrations to compressor and ensure trouble free long life of oil pump.
4. Pulsation Dampener : Built in pulsation dampener to reduce pulsation to entire system of refrigeration
5. Crankshaft and Main Bearings : Bearing surfaces of the high quality nodular cast iron crankshaft are ground to fine tolerances.Main bearings are white metal lined steel backed bushes, pressed into the cast iron bearing covers. Intermediate bearing blocks are provided with split type bearing shell of the same type. Each crankshaft is dynamically balanced together with the counter weights
6. Piston / Connecting Rod Assembly : Perfect sealing and low oil consumption due to 3 compression and 2-oil scrapper rings on each aluminium piston. The nodular iron connecting rod is drilled through for pressure lubrication of the piston pin Steel backed white metal shells on big end and bronze bearing on small end of connecting rod.The complete assembly can be removed from the top for servicing without withdrawing the cylinder liner
7. Cylinder Liner and Suction Valve : Interchangeable cylinder liners are made of finegrained, centrifugally cast, alloy iron. Fine boring and honing results in a mirror smooth running surface.A hydraulic mechanical suction valve lifting mechanism on each individual cylinder achieves loading and unloading. For unloading, the suction valve ring is lifted from its seat in the cylinder collar by spring tension. Admitting controlled oil pressure to the control piston, allowing the suction valve ring to descend on its seat effects loading or cylinder.
8. Discharge Valve Assembly : Three concentric discharge valve rings ensure ample gas passage at low lifting height. The use of sinusoidal springs together with precision machined and lapped surface results in a trouble-free operation for a remarkably long time. Minimum inventory for spares since most parts are identical throughout the CH series compressors.
9. Lubrication System & Oil Filter : Forced Lubrication by an Internal Gear pump directly driven by the Crankshaft. The Pump incorporates two differential pressure regulators to provide separate pressures for two oil systems: Lubrication system and control oil system for operating cylinder loading unloading mechanism. Automatically operating solenoid valve ensures complete unloaded start of compressor. A Metal gauze suction filter element and a throwaway discharge paper filter cartridges are provided for excellent filtering capacity of the lubricating oil.

OPERATIONAL CHARECTERISTICS
 
1. Quick Maintenance : Parts subjected to wear are easily accessible through large service doors with minimum special tools
2. Easy Cleaning : suction gas strainer Inside gauze strainer element can be easily removed and cleaned within no time .
3. Easy maintenance : as piston/connecting rod assembly can be removed without removing the cylinder liner.
4. Minimum Oil Consumption : is ensured by providing three compression rings & two oil scraper rings per piston - thus minimising oil through discharge gas line
5. Safety : is ensured by bult-in arrangement of buffer spring which protects compressor from incidental liquid hammer
6. Extra Safety : is ensured by built-in sight glass, making oil return flow visible hence avoids dry run of commpressor and protect bearing wear and tear
7. Trouble-free Long Running Life : this is possible due to highly effective oil purification by two filters.
   
CH SERIES Compressors are :
 
1. Designed to operate with Ammonia, R22 & other HFC refrigerants.
2. Ideally suitable for continuous duty, process refrigeration liquefaction plants, ice plants, cold storages, etc.
3. Most suitable for industrial refrigeration and low temperature applications
4. Available in single stage as well as two stage versio
ns
 
   
Accessories :

Q: cooling capacity [kW]; Pe: compressor brake power [kW]
The chart rating is for maximum speed: 1000 rpm; Minimum speed allowed: 400 rpm
The capacity and power consumption ratings are possible by interpolation for other speed conditions.
The motor power is 10% over the compressor brake power

Warranty : Every compressor carries a standard warranty against manufacturing defects of 12 months from date of startup / commissioning by CTTPL authorised engineer or 18 months from date of dispatch whichever occurs early. The warranty card must be produced for warranty claims. Standard warranty does not contain consumables like oil, oil filter, gaskets, o-ring etc and warranty is not applicable if failure occurs due to fault in system design
