Research on Automatic Fault Diagnosis of Scraper Conveyor Based on Wavelet Theory and Numerical Control Technology

基于小波理论和数控技术原理,利用小波理论并结合数控技术对刮板输送机减速器、轴承等故障诊断进行了实验研究,试验结果表明,根据小波诊断的谱谱能够精准确定故障类型、位置及程度。该自动诊断技术在西山煤电马兰矿综采工作面刮板输送机故障诊断中的应用表明,诊断精准性高,时效性强,降低了维修成本。

This paper briefly introduces the wavelet theory and the principle of numerical control technology,and makes use of wavelet theory and numerical control technology to make use of wavelet theory and numerical control technology to reduce the reducer of scraper conveyor.The fault diagnosis of bearings is studied experimentally.according to the spectrum of wavelet diagnosis,the fault type,position and degree can be accurately determined.The application of the automatic diagnosis technology in fauts diagnosis of the scraper conveyor shows that the diagnosis is accurate and timely.
