产品描述
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.
If rod packing cooling needed, the stuffing box is jacketed for liquid coolant.
Reciprocating Compressor Basics Components
The crosshead pin should have a replaceable bush bearing.
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.
The crankshaft is connected to drive, to transfer the rotary motion.
When force lubrication is used, drilled oil passage is provided in the crankshaft.
Piston活塞
The piston is the heart of the reciprocating compressor. The piston transfers the energy from the crankcase to the gas in the cylinder. In order to avoid the leakage of compressed gas between the piston and cylinder, the piston is equipped with a set of sliding seals called piston rings. Usually, the piston rings are made of a material, that having self-lubricating property to reduce the slide friction force
between the cylinder and the piston.
