A water pump is a mechanical device that transports or pressurizes liquids. It transmits the mechanical energy or other external energy of the prime mover to the liquid to increase the energy of the liquid. It is mainly used to transport liquid, including water, oil, acid-base liquid, emulsion, suspended lotion and liquid metal.
It can also transport liquids, gas mixtures, and liquids containing suspended solids. The technical parameters of water pump performance include flow rate, suction stroke, head, shaft power, water power, efficiency, etc; According to different working principles, it can be divided into types such as volumetric water pumps and vane pumps. A positive displacement pump utilizes changes in its working chamber volume to transfer energy; Vane pumps use the interaction between rotating blades and water to transfer energy, and there are types such as centrifugal pumps, axial flow pumps, and mixed flow pumps.
