Cylinders & Crankcases

Cylinders

The crankcase, also known as the frame, is an essential component of a reciprocating compressor that houses all its rotating parts, including the connecting rod and crosshead. The frame?s rated horsepower is determined by the maximum horsepower that can be efficiently transferred through the crankshaft to the cylinders.

Crankcases

The cylinder in a reciprocating compressor, especially the low-pressure, larger versions, is usually made of cast iron. The high-pressure but smaller cylinders are constructed of steel. But sometimes, ductile or nodular iron can be employed instead of cast iron.
