Plate valves are recommended up to 20 MPa differential or 40 MPa discharge pressure
and 1800 rpm.
Ring Type Valve
Reciprocating Compressor Basics Components
As the name implies the ring-type valve consisting of concentric ring valve uses one
or more relatively narrow rings arranged concentrically about the centre line of the
valve (see Fig ). These valves have the advantage of a low-stress level due to the
lack of stress concentration points. It is difficult to maintain uniform flow control
across the ring-type valve.
Ring valves are recommended up to 30 MPa differential or 60 MPa discharge pressure
and 600 rpm.
Backup Ring支承环
The construction of the backup ring is similar to the radial ring. As the name
indicate this type of ring is used to backup all the rings when using in the high-
pressure application.
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.
Tangent Ring Radial Ring or Pressure Breaker Ring Backup ring.
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.
Cylinders气缸
The cylinder is a pressure-retaining part of the reciprocating compressor. The cylinder accommodates both suction and discharge valves. For smaller capacity reciprocating compressor (up to 100kW), the cylinder is directly connected to compressor frame. For larger capacity reciprocating compressor (above 100kW), the cylinder is connected to compressor frame through distance piece.
