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 compressor can use narrow piston, due to the use of narrow piston larger valve area for greater efficiency.
Permits a longer stroke and greater capacity.
Separates crankcase from the cylinder, allowing control of oil carryover into the cylinder.
The crosshead pin should have a replaceable bush bearing.
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.
Distance piece may be furnished as single, double, or extra-long type.
The purpose of longer distance piece is to prevent the lubricant entering from crankcase to cylinder. Thereby preventing the gas contamination due to lubrication entering in the cylinder side.
