Description

A New Horizontal Centrifugal Pump with Filter

technical field

The utility model relates to the technical field of centrifugal pumps, in particular to a novel horizontal centrifugal pump with a filter.

Background technique

A pump is a machine that transports fluid or pressurizes the fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. There are many types of pumps and a wide range of applications, including horizontal centrifugal pumps. The centrifugal pump uses the rotation of the impeller to make the fluid centrifugally move, so that the fluid is thrown to the outer edge of the impeller, and flows out of the pump pipeline through the flow channel of the pump casing. The existing horizontal centrifugal pump is designed as a volute channel, and There are impellers and other structures installed inside, and the structure is precise. In addition, the design structure of the drive shaft of the centrifugal pump is too simple.

At present, most unipolar horizontal centrifugal pumps are not designed with a filter mechanism. The fluid carries impurities such as garbage and enters the pump body, which may cause adverse effects on the internal structure of the pump body. The internal impeller is easily stuck, and the delivery work cannot be carried out normally.
