Background
The centrifugal pump is a pump for conveying liquid by means of centrifugal force generated when an impeller rotates, and water is thrown out by driving water to rotate by utilizing impeller blades rotating at high speed, so that the purpose of conveying is achieved. Before the water pump is started, the pump shell and the water suction pipe are filled with water, then the motor is started, the pump shaft drives the impeller and the water to rotate at a high speed, the water is thrown to the outer edge of the impeller to be thrown into a water pressure pipeline of the water pump through a flow channel of the volute-shaped pump shell. The centrifugal pump has various forms such as vertical type, horizontal type, single stage, multistage, single suction, double suction, self suction and the like. The liquid in the impeller is driven by the blades to rotate together with the blades, and the centrifugal force generated by the rotation makes the liquid move outwards from the center and obtain momentum increment.
When the centrifugal pump is used, the motor drive can generate strong vibration, and the vibration force can affect the service life of the whole centrifugal pump and the water pumping efficiency. Moreover, in order to isolate the impurities at the water inlet into the centrifugal pump, a filter screen is usually installed at the water inlet for filtering, but the filter screen is easy to block after being used for a long time, so that the cleaning frequency of the filter screen is increased.
