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.
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.
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.
Radial Ring or Pressure Breaker Ring径向环或压力断路器环
The radial ring or pressure breaker ring is cut into three segments so that each cut
lies on the side of a radial direction of the ring. The cuts in the ring are used to
break down the pressure act on the ring. The radial ring is the first ring of road
packing to face the cylinder pressure.
Normally most of the cylinders used in the process industries are equipped with replaceable liners. The purpose of the liner is to provide a renewable surface to the wearing portion of the cylinder. This saves the cost of replacing a complete cylinder once the bore has been worn out or metal scoring.
