The working principle of common power pumps

Thread Content

The dynamic pump relies on the force of the rapidly rotating impeller on the liquid to transfer mechanical energy to the liquid, increasing its kinetic energy and pressure energy, and then converts most of the kinetic energy into pressure energy through the pump cylinder to achieve transportation. Power pumps are also called impeller pumps or vane pumps. Centrifugal pumps are the most common powered pumps. The lift generated by a dynamic pump at a certain speed has a limited value, and the lift changes with the flow rate. ； Stable operation, continuous delivery, and no pulsation in flow and pressure ； Generally, there is no self-priming ability. The pump needs to be filled with liquid or the pipeline must be evacuated before it can start working. ； Wide range of applicable performance ； It is suitable for transporting clean liquids with very low viscosity. Specially designed pumps can transport mud, sewage, etc. or water to transport solid objects. Power pumps are mainly used for water supply, drainage, irrigation, process liquid transportation, power station energy storage, hydraulic transmission and ship jet propulsion, etc.
