Description

Anti-blocking slurry pump

Technical Field

The utility model belongs to the technical field of application of slurry pumps, and particularly relates to an anti-blocking slurry pump.

Background

The slurry pump is a machine which increases the energy of solid-liquid mixed medium by the action of centrifugal force and converts electric energy into kinetic energy and potential energy of the medium. The method is mainly suitable for the following steps: the fields of mine, power plant, dredging, metallurgy, chemical industry, building materials, petroleum and other industries. 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.
