| Abstract: | The relation of centrifugal compressor surge and rotating stall were simply elaborated,and the mechanism of compressor surge and rotating stall was emphasizely analysed.Because abnormal vibration and noise in machine are major traits while compressor had some faults,and vibrational signs were periodic signals,frequency analysis was applied in breakdown diagnosis of centrifugal compressor,which have been very effective. |
