Methods and devices for constructively using the pressure pulsations in reciprocating compressors installations

摘要

Apparatuses and methods for constructively use pressure pulses to enhance the volumetric efficiency of a reciprocating compressor are provided. An apparatus includes a gas circulation device and a controller 110. The gas circulation device provides a path through which the gas circulates between a reciprocating compressor 10 and a volume bottle 50 buffering the reciprocating compressor from an installation. The gas circulation device is configured to have to have a resonance frequency substantially equal to a frequency of performing compression cycles in the reciprocating compressor. The controller 110 is configured to control timing of switching a valve located between the reciprocating compressor and the gas circulation device, in order to use constructively pressure pulsations occurring in the gas circulation device, to enhance the volumetric efficiency of the reciprocating compressor.
