Reciprocating Compressor

Definition - What does Reciprocating Compressor mean?

A Reciprocating Compressor is a positive-displacement device that works on a reciprocating principle to deliver gas at high pressure. The reciprocating motion is enabled by pistons within the device. It can be divided into two types, i.e., Separable (High speed) compressor and Integral (Low speed) compressor. Large reciprocating natural gas engines are used to move natural gas, to generate low-pressure plants and supply the gas at high pressure for well drilling.

Petropedia explains Reciprocating Compressor

Reciprocating Compressors suck natural gas from the suction manifold and then pistons which are driven in a reciprocating motion by the crankshaft move the natural gas to a cylinder, which is also known as a compression cylinder. This entire process is powered by an internal combustion engine. If we increase the operating life of the compressor then the packing system will wear and rings will be worn hence it will result in higher leak rates.

The major components of the Reciprocating Compressor are:

  • Cylinder
  • Frame
  • Distance piece
  • Crankshaft
  • Piston
  • Bearings
  • Compressor Valves
