Study on Diagnostic Technique of Piston Compressor

In order to improve the effectiveness and correctness of the diagnostic technique,the method that combining the rough set theory and wavelet energy spectrum theory was used to diagnose the fault of the piston compressor.The rough set diagnostic theory model was established.The steps of diagnostic for piston compressor were given,then the computer algorithm of fault diagnosis was founded.This method was applied on site,the robustness of the method was verified.
