| Abstract: | The method with the art of vibrating spectral analysis to get characters of compressor fault is brought up and discussed, which is according to the working principle and character of 16SGT-MH6 refrigerator compressor used in oil field. Firstly it gathers vibrating signals in pivotal parts, and these signals will be used as original signals. Then we will analyze and dispose these datas specially with intelligent system of fault diagnosis. Consequently we achieve the result of estate inspection and fault diagnosis of the compressor. The method has been applied 42 times in workstations of Talimu oil field, and the nicety rate reaches 85%. |
