The centrifugal pump drives the blades to rotate at a high speed by a motor, and the pumped liquid is discharged along a drainage pipeline at a high speed. Before the centrifugal pump starts the motor to drive the impeller to move, the water suction pipe and the pump body are filled with water, and then the water is driven by the impeller to rotate at a high speed and is thrown out of the pump body under the action of centrifugal force and flows into a pipeline along a water outlet. The water in the water pump is thrown out to form vacuum, and the water in the water suction pool flows into the pump shell under the action of atmospheric pressure, so that continuous water flow is formed. Is arranged on the drainage pipeline close to the drainage pipe. The gate valve mainly has two functions: firstly, the actual drainage parameters (such as flow and lift) of the centrifugal pump can be adjusted through the action of the centrifugal pump; secondly, the centrifugal pump is closed when the centrifugal pump is to be opened for drainage, so that the starting current of the motor is correspondingly reduced, the running load of the motor is reduced, and the shaft power of the pump is greatly reduced. The check valve is used for preventing water in the drainage pipeline from falling rapidly under the action of gravity when the pump is stopped, and because the impact destructive power of high-speed running water on the water pump and the pipeline is very large, when the water pump stops suddenly due to a certain special reason, the check valve can be closed automatically and rapidly, and the water pump and the pipeline are prevented from being damaged by high-pressure water in the pipeline. Bypass valve: when the water pump is started again, water can be filled into the pump. Air release valve: before the water pump is started, water is filled into the pump, and air in the pump is discharged through an air discharge valve. A vacuum gauge: and measuring the vacuum degree of the water suction port of the water pump. A pressure gauge: and measuring the pressure of the water outlet of the water pump. Three main drainage pipes are selected for drainage, when the water inflow is normal, two water pumps drain water simultaneously, and an independent pipeline is used for each time, and a pipeline for the third time is reserved for standby; when the water inflow of the mine reaches the maximum value, other water pumps are started to drain water, and at the moment, the three pipelines are started simultaneously. Different working conditions are met.
The jet pump comprises a nozzle, the nozzle is arranged in a suction chamber, the suction chamber is connected with a mixing pipe, the mixing pipe is connected with a diffusion pipe, the diffusion pipe is connected with a pressure outlet pipe, the suction chamber is also connected with a jet pump opening arranged on a water pump, and the nozzle is connected with a high-pressure water flow pipeline.
In drainage system in the pit, will fill water with the pipe that absorbs water in the pump chamber before the centrifugal pump starts, just so can normally start the water pump, if the pump chamber does not form the vacuum with the pipe that absorbs water and just open the water pump, it is the same with sump internal pressure size to absorb water the inside, and external pressure can not be in the water pressure suction pipe, like this, the water pump will not have water to irritate the condition under full and move, can produce very big heat, lead to the life reduction of water pump. The utility model discloses a jet pump carries out the evacuation for the centrifugal pump, utilizes the high-speed efflux of jet pump to drive the air outflow of pump intracavity, forms "siphon phenomenon", then the water in the sump is sucked in the pipe and the pump chamber that absorbs water.
The water suction pipe is also provided with a water filter at one end of the water bin. The water filter prevents impurities in water from entering the water pump.
A liquid level sensor is also arranged in the water sump and is connected with an audible and visual alarm device. And when the water level in the water bin exceeds the warning water level, a sound and light alarm is given out to remind the user of draining water.
The utility model has the advantages of reasonable design, mine drainage system adopts centrifugal water pump, sets up bleed valve, manometer, vacuum meter simultaneously and conveniently monitors the operating mode, adopts the jet pump to evacuate centrifugal pump, and system safe and reliable, reasonable arrange that the drainage pipe way is fit for different operating modes, the utility model discloses still set up the water purifier and improve water pump life, set up liquid level alarm device and make things convenient for sump liquid level real time monitoring.
