How Does a Reciprocating Compressor Work? Complete Guide for Industrial Users

How Does a Reciprocating Compressor Work? Reciprocating compressors convert rotational energy into high-pressure gas by driving a piston back and forth inside a cylinder. Because every stroke pushes—or reciprocates—gas, these machines deliver precise volumes at high pressures, which explains their popularity in petrochemical, hydrogen and nitrogen boosting lines. 1. Core Components and Flow Path Crankshaft & MotorThe crankshaft, powered directly by an electric motor, turns continuously; therefore, it changes rotary motion into linear piston travel. Connecting Rod & PistonAs the rod swings, the piston moves up and down, alternately increasing and decreasing cylinder volume. Suction & Discharge ValvesWhen the piston descends, suction valves open automatically, drawing process gas into the […]
