Poppet Valve
Reciprocating Compressor Basics ComponentsThe poppet valve is used for low-speed
compressor and gas contain oil particles. The poppet valves are high lift valves, due
to high lift the pressure drop across the valve is low.
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.
The packing rings are the important element of rod packing assembly. The below-listed
packing rings are widely used in a reciprocating compressor.
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.
Permits a longer stroke and greater capacity.
Separates crankcase from the cylinder, allowing control of oil carryover into the cylinder.
The rider ring is one-piece configuration, to accommodate the rider ring the piston is segmented construction. As per API-618 one-piece rider rings are a required. Rider band life can be extended by rotating a piston 120° to 180° at each overhaul.
