[0002] A chemical centrifugal pump refers to a centrifugal pump used in the chemical industry. Compared with other types of pumps, a chemical centrifugal pump has the advantages of simple structure, low wear resistance, smooth operation, low noise, uniform water discharge, easy adjustment and high efficiency. Therefore, a chemical centrifugal pump has 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. The water in the impeller groove is thrown to the periphery and flows into the pump casing under the action of centrifugal force. As a result, the pressure at the center of the impeller decreases. This pressure is lower than the pressure in the water inlet pipe. Under the action of this pressure difference, water flows from the suction tank into the impeller.
