Abstract

The application discloses a kind of based on the fault mechanism diagnosis method of centrifugal compressor of multiple index, obtains the exhaust flow and exhaust pressure signal when centrifugal compressor operates;Flow and pressure signal are filtered;According to the signal after filtering, the energy index of centrifugal compressor, unimodal index, power index are constructed;And according to the characteristic index obtained by measurement calculation and the characteristic index under benchmark operating condition are compared to obtain the state measurement of each characteristic index, determine index is calculated, centrifugal compressor rotating stall and surge fault can be quickly identified;Centrifugal compressor abnormal operating condition can be well realized discrimination and classification, with strong versatility and robustness.
