Water Pump
A water pump is a machine that conveys or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid, and is mainly used to convey liquids including water, oil, acid and alkali liquids, emulsions, suspended emulsions and liquid metals. Can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters of water pump performance are flow, suction range, head, shaft power, water power, efficiency, etc.; according to different working principles can be divided into volumetric pumps, vane pumps and other types. Volumetric pump is the use of its studio volume changes to transfer energy; vane pump is the use of rotary vane and water interaction to transfer energy, there are centrifugal pumps, axial pumps and mixed flow pumps and other types.
