Both the Compressor manufacture and the Purchaser should ensure the Rod load maximum value to know the reciprocating compressor limits. Also, the rod load curves and peak rod load/reversal values provide an important insight to predict the health of a reciprocating compressor.
The crosshead pin should have a replaceable bush bearing.
Tangent Ring Radial Ring or Pressure Breaker Ring Backup ring.
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.
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.
For a horizontally mounted cylinder, along with piston rings, an additional ring called wear band or rider ring is used to lower the wear between cylinder and piston.
