Description

Vortex pump

Technical Field

The utility model belongs to the technical field of vortex pumps and relates to a vortex pump.

Background

A peripheral pump (also called a vortex pump) is a vane pump. The method is widely applied to the departments of shipbuilding, light textile, chemical engineering, metallurgy, mechanical manufacturing, aquatic product cultivation, fixed fire-fighting and pressure-stabilizing, heat exchange units, agricultural remote sprinkling irrigation and the like. The impeller is a disc, blades on the circumference are uniformly arranged in a radial shape, an annular flow channel is formed between the pump body and the impeller, the suction inlet and the discharge outlet are both arranged on the outer circumference of the impeller, and a partition wall is arranged between the suction inlet and the discharge outlet, so that the suction inlet and the discharge outlet are separated. The vortex pump mainly transfers energy to liquid in a mode that an impeller in a pump head continuously works on the liquid for multiple times, so that the liquid generates higher pressure and is sprayed out from an outlet. Under the action of centrifugal force, the liquid thrown out by the impeller can continuously impact and collide with the inner wall of the pump body and the partition tongues at the end parts of the partition walls, so that high noise can be generated.
