Bearing
The main and connecting rod bearings should be split-sleeve, steel-backed, babbitted
insert type. Antifriction bearing shall be used for compressor rating less than
150kW. As per API-618 trapper roller bearings are used as the main bearing for
compressor rating less than 150kW.
The Figure shows a drilled crankshaft.
Crankshafts should have removable balance weights to compensate the rotary unbalance
as well as reciprocating unbalances. The crankshaft should be dynamically balanced
when above 800 rpm.
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.
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.
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.
