This paper describes the case of condition monitoring for reciprocating compressor valves by acoustic technique. The valve plate is the most fragile part of reciprocating compressor and once valve is broken, compressor tend to be in trouble. The leading cause of valves to be broken is tumbling phenomenon. This paper focuses on tumbling phenomenon of valves, and describes how to catch this phenomenon by condition monitoring system.
