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.
The crankshaft is connected to drive, to transfer the rotary motion.
When force lubrication is used, drilled oil passage is provided in the crankshaft.
Crank Shaft曲轴
Larger compressors, normally above 150 kW(200 hp), the crankshaft is made up of
forged steel. Compressor less than or equal to 150kW, the crankshaft is made up of
ductile iron.
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.
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 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.
