Mining explosion-proof submersible electric pumps need to undergo minor repairs or comprehensive overhauls after being used for a certain period of time to prevent problems before they occur and ensure the normal operating performance of the pump. Mainly start from the following aspects
. You can clean the well and set up sewage barriers to improve the water quality and reduce the water quality. Because the poor water quality of the mine explosion-proof submersible electric pump will have adverse effects on the normal operation of the pump, and over time it will cause malfunctions, so we should start with inspection. The incoming water quality of mining displacement pumps starts with sand content (the volume ratio of sand content in well water should not be greater than .%) and debris content.
Lift the water inlet horn of the pump to a distance of more than one meter and not less than half a meter from the bottom of the mine.
Check the gap of the sealing ring (note: the gap size of the sealing ring is related to the inner diameter of the ring), the installation position and installation quality of the impeller (such as whether the positioning key of the impeller is moving, whether the locking nut is loose, (Whether the gap between the impeller and the pump casing meets the requirements), repair, adjust or replace parts. Finally, assemble the water pump. . Check the wear and fixation of the impeller. If the nut is loose, tighten it in time. If you find that the impeller is partially worn, you should remove the impeller for repair or replacement.
Eliminate cavitation factors, improve the anti-cavitation performance of the pump, and appropriately reduce the installation height of the pump.
