Background
The pump is a general-purpose machine and has wide application. With the development and evolution of water pumps, various water pumps are provided, the names of the water pumps are eight-door, and the calling and classification of the water pumps are different in various water pumps. Centrifugal submersible pumps are one type of centrifugal submersible pumps and mainly comprise a pump shell, an impeller, a pump shaft, a pump frame and the like. Before starting, the pump is filled with water, the impeller which rotates after starting drives the water in the pump to rotate at high speed, and the water is centrifugally moved, thrown out outwards and pressed into the water outlet pipe. After the water is thrown out, the pressure near the impeller is reduced, and a low-pressure area is formed near the rotating shaft. The pressure is much lower than the atmospheric pressure, and the outside water can open the bottom valve and enter the pump from the water inlet pipe under the action of the atmospheric pressure. The water rushed in is thrown out again in high-speed rotation along with the impeller and is pressed into the water outlet pipe. The impeller is driven by the power machine to rotate at a high speed continuously, and water is continuously pumped from a low position to a high position.
The inlet end and the water outlet end of the existing centrifugal pump are butted through connecting flanges and are fixedly connected through bolts after being butted. After long-time use, the sealing performance of the connecting position of the inlet end and the water outlet end of the centrifugal pump with the structure is poor, so that the leakage problem is easy to occur, and particularly, the leakage problem is more prominent in a high-power centrifugal pump.
