How a powered pump works

24 Jan 2022Email

The power pump relies on the force of the rapidly rotating impeller on the liquid to transfer the mechanical energy to the liquid to increase its kinetic energy and pressure energy, and then through the pump cylinder, most of the kinetic energy is converted into pressure energy to achieve transportation. Power pumps are also known as impeller pumps or vane pumps. Centrifugal pumps are the most common powered pumps.

The head generated by the power pump at a certain speed has a limited value, and the head changes with the flow; the work is stable, the conveying is continuous, and the flow and pressure have no pulsation; generally, there is no self-priming ability, and the pump needs to be filled with liquid first or the pipeline is pumped. It can start to work after being vacuumized; it has a wide range of applicable properties; it is suitable for conveying clean liquids with very small viscosity, and the specially designed pump can convey mud, sewage, etc. or water conveying solids. Power pumps are mainly used for water supply, drainage, irrigation, process liquid transportation, power station energy storage, hydraulic transmission and ship jet propulsion.
