Improving the reliability of the operation of reclamation pumping stations by using self-starting electric motors

Abstract

The results of full-scale studies of unsteady processes during self-starting of electric motors at pumping stations are presented. The simulation of transient processes in the modes of self-starting of an asynchronous electric drive of a pumping unit is considered in order to identify the nature of the change in flow, pressure and moment of resistance on the pump shaft in the noted modes. The transient processes in the run-down modes when the pump loses the drive, as well as the self-starting of the asynchronous electric drive of the pumping unit, are investigated. In order to improve the technical and operational performance of reclamation pumping stations, the necessity of using the self-starting mode of electric drives of pumping units is substantiated.
