Reciprocating compressor

Reciprocating compressor

A reciprocating compressor is a compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.

The intake gas enters the suction manifold, then flows into the compression cylinder where it gets compressed by a piston driven in a reciprocating motion via a crankshaft, and is then discharged. We can categorize reciprocating compressors into many types and for many applications. Primarily, it is used in a great many industries, including oil refineries, gas pipelines, chemical plants, natural gas processing plants and refrigeration plants. One specialty application is the blowing of plastic bottles made of Polyethylene Terephthalate (PET).

Portable compressors

Reciprocating compressors were formerly used for powering portable tools such as pneumatic drills. The unit was mounted on a trailer or a lorry and comprised a reciprocating compressor driven, through a centrifugal clutch, by a diesel engine. The engine's governor provided only two speeds:

* idling, when the clutch was disengaged
* maximum, when the clutch was engaged and the compressor was running

Modern versions use rotary compressors and have more sophisticated variable governors.

*Vapor-compression refrigeration
*Diving air compressor
