Description

Technical Field

[0001] The utility model relates to the technical field of slurry pumps, in particular to a high-lift slurry pump device. Background Art

[0002] Slurry pump refers to a kind of machine that increases the energy of solid-liquid mixed medium by the action of centrifugal force (rotation of the pump impeller), and converts electrical energy into kinetic energy and potential energy of the medium. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the volute pump casing, the liquid slows down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipe at a higher pressure and is sent to the 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. Since the pressure above the liquid surface in the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. It is mainly applicable to: mining, power plants, dredging, metallurgy, chemical industry, building materials and petroleum industries;

[0003] However, currently the raw materials entering the slurry pump are not processed and filtered in advance, so that larger particles in the raw materials directly enter the slurry pump. When more particles rotate and collide inside the slurry pump, they are likely to damage the internal mechanism of the slurry pump, resulting in a reduction in the service life of the internal parts of the slurry pump. Therefore, the utility model provides a high-lift slurry pump device to meet people's needs. Utility Model Content
