Abstract

Analysis of the representative statistical data showed that main causes of frequent expensive major repairs of the section pumps in the pump chamber of the main mine drainage system at the Udachny mine are failures of the impellers and other basic components due to continuous emergency operation of those pumps. Emergency operation refers to the operation of the section pump in the critical rotor axial position caused by unsatisfactory hydraulic balancing device health. The main causes of the continuous emergency operation of the section pumps JSH 200 produced by Mackley Pump and the section pump TSNS -350-1100 produced by Link-Product are failures of rotor axial position sensors. In case of a sensor failure, automatic protection of the pump becomes impossible when the rotor is in its critical axial position. The present article aims to prove that temperatures of the rear bearing of the section pump can be a diagnostic criterion of its emergency operation.
