Abstract
A system for remote diagnosis of the state of wear of the suction and delivery valves of reciprocating compressors comprises at least one piezoelectric seismic sensor, applied to each cylinder of the compressor. The sensor transforms the vibrations generated by the noise of the valves into an electric signal. By appropriate amplification and filtering, the envelope of the resulting narrow band signal is obtained. The signal obtained is then digitized, and transmitted to a remote diagnostics center for monitoring.
