[0002] A centrifugal pump is a pump that transports liquids by the centrifugal force generated by the rotation of the impeller. Centrifugal pumps are widely used in the power, metallurgy, coal, building materials and other industries to transport slurries containing solid particles because of their wide head range, uniform flow, stable operation and low equipment installation and maintenance costs.

[0003] When a centrifugal pump is in use, there are many particulate impurities in the extracted material, and the larger particles are easy to scratch the impeller, or even cause blockage inside the centrifugal pump body, thereby affecting the delivery efficiency of the centrifugal pump.
