Poppet valves are recommended up to 15 MPa differential pressure or 30 MPa discharge
pressure and 600rpm.
Plate Type Valve
Reciprocating Compressor Basics Components
The plate type valve contains concentric rings of valve plates. The concentric ring
valve plates are a single element. Since the valve plate is made of a single element,
flow control is much easier when compared to other types of valves.
The stress act on the valve plate is much higher than the Poppet valve. These type of
valves are widely used compressor handling of Oil-free gases.
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.
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.
If rod packing cooling needed, the stuffing box is jacketed for liquid coolant.
Reciprocating Compressor Basics Components
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.
Piston活塞
The piston is the heart of the reciprocating compressor. The piston transfers the energy from the crankcase to the gas in the cylinder. In order to avoid the leakage of compressed gas between the piston and cylinder, the piston is equipped with a set of sliding seals called piston rings. Usually, the piston rings are made of a material, that having self-lubricating property to reduce the slide friction force
between the cylinder and the piston.
