The method is mainly suitable for the following steps: in the fields of industries such as mines, power plants, dredging, metallurgy, chemical engineering, building materials, petroleum and the like, a slurry pump conveys a mixture of solid particles containing dregs and water. However, the slurry pump belongs to one of centrifugal pumps in principle, and is mainly used for conveying slurry in systems such as converter dedusting water, blast furnace gas washing water, continuous casting turbid circulating water, steel rolling turbid circulating water and the like in steel enterprises.

Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtains energy, and the liquid leaves the outer edge of the impeller at high speed and enters the volute pump shell. In the volute pump casing, the liquid is decelerated due to the gradual expansion of the flow passage, part of kinetic energy is converted into static pressure energy, and finally the static pressure energy flows into a discharge pipeline at higher pressure and is sent to a required place. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller, and the liquid is continuously pressed into the impeller because the pressure above the liquid level of the storage tank is higher than the pressure at the inlet of the pump.
