Device for maintaining the nominal operating modes of the section pump of a mine district drainage system in conditions of intensive silting of water reservoirs

This paper presents in detail a device that allows you to maintain the nominal operating modes of centrifugal section pumps in real time. The practical implementation of this device will reduce the risk of failure of a centrifugal section pump mounted on a mine district drainage plant by constantly maintaining the nominal pressure in its suction pipe, which reduces the risk of the rotor critical axial shift.
