Vane pump 3D model

A pump is a machine that transports or pressurizes liquid. It transmits the mechanical energy or other external energy of the prime mover to the liquid to increase the energy of the liquid, which is mainly used to transport liquids including water, oil, acid lye, emulsion, suspension emulsion and liquid metal. It can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters of pump performance include flow, suction, head, shaft power, water power, efficiency, etc. According to different working principles can be divided into positive displacement pump, vane pump and other types. Positive displacement pump is the use of its studio volume changes to transfer energy; Blade pump is the use of rotary blade and water interaction to transfer energy, centrifugal pump, axial flow pump and mixed flow pump and other types.
