Abstract

The invention discloses a centrifugal pump with the variable impeller width. The centrifugal pump comprises a centrifugal pump body, an inlet sealing ring, an impeller mounting seat, connecting lug plates and a sealing sleeve. The inlet sealing ring is arranged in the centrifugal pump body. A water inlet is formed in the upper portion of the inlet sealing ring. The impeller mounting seat is arranged on the other side of the inlet sealing ring. A pump transmission shaft is mounted on one side of the impeller mounting seat. A flat key is arranged between the impeller mounting seat and the pump transmission shaft. A water outlet is formed in the top of the centrifugal pump body. The connecting lug plates are mounted on the two sides of the water outlet. An O-shaped sealing ring is mounted onone side of the pump transmission shaft. The sealing sleeve is mounted on one side of the O-shaped sealing ring. The centrifugal pump has the beneficial effects that by arranging a fixed impeller anda movable impeller, the width of the impellers can be adjusted according to the use situation, and using is convenient; and the flow and pressure of water in the centrifugal pump can be monitored in real time, and the centrifugal pump is prevented from being damaged due to overpressure.
