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 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 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.
Normally the piston is made up of less weight materials such as aluminium and aluminium alloys, this is to reduce the reciprocating compressor Shaking forces and Rod load. For larger diameter pistons, hollow type pistons are used to reduce the weight.
