Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump equipment technology, specifically a centrifugal pump for water treatment. Background Technology

[0002] A centrifugal pump is a common fluid transport device that uses centrifugal force to drive fluid from a lower elevation to a higher or farther location. When the pump starts, the motor drives the impeller to rotate at high speed. The blades on the impeller cause the liquid to rotate, generating centrifugal force. Under the action of centrifugal force, the liquid is thrown towards the edge of the impeller and flows out from the pump outlet. At the same time, because the liquid is thrown out, a low-pressure zone is formed in the center of the impeller, attracting liquid to continuously flow in from the pump inlet, thus achieving continuous liquid transport.

[0003] During operation, single-stage centrifugal pumps may experience blade wear due to prolonged operation, leading to "air binding" inside the pump body. This prevents the pump from being fully filled with liquid, resulting in insufficient subsequent pressure and affecting the overall efficiency of the centrifugal pump. Therefore, it is necessary to improve its structure to increase the efficiency of the centrifugal pump and reduce maintenance cycles and costs. Utility Model Content
