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

Abstract

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