- Reciprocating compressor
A reciprocating compressor is a compressor that uses
piston s driven by acrankshaft to deliver gases at high pressure.

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 plant s,natural gas processing plants andrefrigeration plants. One specialty application is the blowing of plastic bottles made ofPolyethylene Terephthalate (PET).Portable compressors
Reciprocating compressors were formerly used for powering portable tools such as
pneumatic drill s. The unit was mounted on a trailer or alorry and comprised a reciprocating compressor driven, through acentrifugal clutch , by adiesel 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 runningModern versions use rotary compressors and have more sophisticated variable governors.
