The working principle of a seawater pump is similar to that of a regular water pump. Centrifugal force generated by the rotation of the impeller propels the liquid from the center to the edge of the impeller, simultaneously generating pressure to deliver the liquid to the desired location. The specific process is as follows:
Impeller Rotation: Driven by a motor, the impeller rotates, and the blades on the impeller push the liquid.
Centrifugal Force Generation: The liquid at the center of the impeller generates centrifugal force due to the impeller's rotation, throwing it towards the impeller edge.
Pressure Transmission: Under pressure, the liquid at the impeller edge passes through the discharge pipe and is delivered to the desired location.
Liquid Suction: When the liquid at the center of the impeller is drawn away, a vacuum or low-pressure state is created at the impeller inlet. Liquid in the suction tank is then forced into the impeller inlet under atmospheric or hydraulic pressure, thus continuously drawing in and discharging liquid.
