Valve气阀Reciprocating compressors generally use one of three types of valve configurations:
Rod Packing活塞杆填料
Rod packing is required to prevent the gas leakage along the piston rod where it
passes through the crank end cylinder closure.

The compressor can use narrow piston, due to the use of narrow piston larger valve area for greater efficiency.

Cross Head十字头
All industrial compressors are equipped with crosshead. The crosshead is used to
guide the piston in the cylinder bore. The following are the advantage of the crosshead.

Bearing
The main and connecting rod bearings should be split-sleeve, steel-backed, babbitted
insert type. Antifriction bearing shall be used for compressor rating less than
150kW. As per API-618 trapper roller bearings are used as the main bearing for
compressor rating less than 150kW.
Different types of rings are used for lubricated or non-lubricated service. In the case of non-lubricated service, the rings shall have good self-lubricated property. Piston rings are made up of PEEK and other fluorocarbon compounds.
