[0002] The working principle of the submersible centrifugal pump is based on the hydraulic principle and centrifugal force. The water pump and the motor are connected by the same shaft. When the impeller rotates at high speed, the liquid flies away from the impeller under the action of centrifugal force and then gradually slows down and increases pressure in the pump casing, and finally is discharged from the pump outlet. This design enables the submersible centrifugal pump to efficiently transport the medium at the bottom of the pool to the ground, and is widely used in oil transportation, mine rescue, construction drainage, agricultural irrigation, industrial water circulation and other fields.
