Application of Wavelet Envelope Spectrum Analysis in Air Blower Rotating Stall Failure Diagnosis

Abstract:

Article Preview

Based on qualitative analysis in mechanism of air blowers rotating stall, wavelet envelope spectrum are applied in failure signal analysis of catalytic cracking unit main air blower in a petrochemical company. By utilizing time & frequency localization characteristics of wavelet analysis and extracting detail characteristic of air blower failure, and by Hilbert envelope spectrum analysis, faults are determined and located. The method is applied to failure signal analysis and processing of catalytic cracking unit main air blower in a petrochemical company, which has made a good progress.
