Control method for stage degradation of centrifugal pump unit parts in the system of technical condition monitoring and automatic diagnosis

Reliable operation of a centrifugal pump unit, as an electric motor, which is reliable link in the composition depends on many factors, well important factor trouble-free unit reliability rolling bearings. The presented work devoted to study processes multi-stage failure parts bearing i.e., repeatedly occurring self-eliminating failures same nature - intermittent failures, establishing dependences vibration changes degradation process, developing control methods and for identifying predicting staged processes.
