Reciprocating compressors generally use one of three types of valve configurations:
The connecting rod is made up of forged steel for 150 kW (200 hp) reciprocating
compressor. For compressor less than or equal to 150kW, ductile iron material is
used.
The packing rings are the important element of rod packing assembly. The below-listed
packing rings are widely used in a reciprocating compressor.
Permits a longer stroke and greater capacity.
Separates crankcase from the cylinder, allowing control of oil carryover into the cylinder.
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.
Compartments in the distance piece collect and control packing leakage when the gas is toxic or flammable. The leakage can be direct to a flare or buffer inert gas is used to prevent the toxic gas leakage to the atmosphere.
