Abstract
The objective is to provide a method about equipment condition monitoring and fault diagnosis. The method could indicate equipment operating parameters, working conditions and specific status. We used CDMS system monitoring mine hoist key parts of the vibration velocity, introduces the vibration sensor reasonable decorate, in the time domain analysis of speed amplitude values, in frequency domain speed spectrum analysis, according to the monitoring signal analysis processing results, give the diagnostic conclusions that the gear of second shaft have uniform force, and a little corrosion, peel and eccentric, puts forward that we should strengthen vibration monitoring about the second shaft of speed reducer, Observe reducer wear trend using the iron spectral analysis, Supervise lubricating oil quality, change oil when necessary.
