Description

Technical Field

[0001] The utility model relates to a control device, in particular to a self-priming pump control device, belonging to the technical field of self-priming pumps. Background Art

[0002] Due to normal water gushing, temporary water tanks are set up at underground working faces. The accumulated water in the tanks must be pumped out by water pumps and discharged into the drainage system to control the accumulated water above the lowest water level line.

[0003] However, if too much water is pumped, the water pump body will be filled with a large amount of gas and will run idle without water, which will endanger the safe operation of the water pump and cause energy loss. In the automatic control method originally adopted by the submersible pumps in the water tanks of the working face in the mine, high and low water level control uses bare wires as trigger points, which not only does not meet the underground explosion-proof requirements, but also the bare wires are used as water level control. When the wires are oxidized or there is too much dirt on the surface, they will fail and cannot be triggered, resulting in the water level being too low and the water pump being dry, causing equipment overheating and damage.
