Chemical centrifugal pumps refer to centrifugal pumps used in the field of chemical engineering. Compared with other types of pumps, chemical centrifugal pumps have the advantages of simple structure, low wear, smooth operation, low noise, uniform water output, convenient adjustment, and high efficiency. Therefore, chemical centrifugal pumps have been widely used. The working principle of a chemical centrifugal pump is that when the pump is filled with water, the impeller rotates to generate centrifugal force. Under the action of centrifugal force, the water in the impeller channel is thrown outward and flows into the pump casing. As a result, the pressure at the center of the impeller decreases, which is lower than the pressure inside the inlet pipe. Under this pressure difference, water flows into the impeller from the suction pool. This way, the water pump can continuously absorb water and supply water
