The Reciprocating Compressor Fault Analysis Based on ORSGWT

Abstract:

It can be found that the redundant second generation wavelet function had more accurate analysis ability compared with the other wavelets and wavelet packets through simulation signals analyses. The analyses of the industrial signals may be more difficult due to its complex character. The de-noising ability of the redundant second generation wavelet to the industrial noise was confirmed by comparing with wavelet packets. But the signal after de-noising still expresses confused and makes analysis difficult. The optimized redundant second generation wavelet transform (ORSGWT) method was established with Newton interpolation and scale thresholds. Then the fault signals of valve block gap being processed with ORSGWT method were smoother and more apparent about the fault characters comparing with the normal state signals.
