PERFORMANCE STUDY OF A PROTOTYPE RECIPROCATING PISTON COMPRESSOR WITH SPECIAL ATTENTION TO VALVE DESIGN AND GAS PULSATION

摘要

A theoretical case study is presented where various valve, discharge and suction cavity parameters of a prototype reciprocating compressor were varied to study the resulting efficiency changes of the compressor. The paper presents and illustrates one way simulation can be used for design improvements. For this particular prototype, it turned out that changes in effective valve flow areas had the most significant influence on performance efficiency. Other effects such as gas pulsations, valve mass, etc., are also discussed.
