Technical Field
The utility model relates to a mine drainage equipment technical field, in particular to an unmanned on duty list inhales formula centrifugal water pump device for mine drainage in pit.
Background
Centrifugal water pumps are widely used for liquid transportation in various industries. Before the centrifugal water pump is started, the pump shell and the inlet water pipe are filled with conveyed liquid. After the impeller is started, the impeller is driven by the shaft to rotate at a high speed, and liquid is discharged out of the pump shell at a high pressure and flows into the pipeline to be conveyed under the action of centrifugal force. Because the liquid is discharged, a certain vacuum is formed in the center of the impeller, the liquid in the water sump is pressed into the impeller under the action of atmospheric pressure, and the liquid can be continuously sucked and discharged as long as the impeller continuously rotates. When air or air leakage of the water inlet pipe exists in the pump shell, the pressure difference between the atmospheric pressure and the center of the impeller is insufficient to press liquid in the water sump into the water pump, the centrifugal pump has no self-suction capability, and the centrifugal pump cannot convey the liquid, which is called 'air-bound phenomenon'. In order to fill the pump casing with liquid, a bottom valve (check valve) and a strainer are usually installed at the bottom of the suction pipe to prevent impurities from entering the pump. If the bottom valve seal is damaged, the water pump and the suction pipe are not filled with water, and the centrifugal pump cannot work.
For some powerful centrifugal pumps, replacing the bottom valve is also a very labor intensive task. And the water pump on the rescue site does not work to pump water, so that the time and the opportunity of rescue are delayed, and greater loss is certainly caused, so that the problems that the water pump is not filled with water, air leaks, and the water pump does not work to pump water are always difficult to solve.
