Background

The slurry pump refers to a device for converting electric energy into kinetic energy and potential energy of a medium by a machine for increasing energy of a solid-liquid mixed medium by the action of centrifugal force (rotation of an impeller of the pump). The method is mainly suitable for the following steps: under the action of centrifugal force, liquid is thrown from the center of an impeller to the outer edge to obtain energy, and leaves the outer edge of the impeller at high speed to enter a 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 greater than the pressure at the inlet of the pump;
