Water pump

          A water pump is a machine that delivers or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, which increases the liquid energy and is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspoemulsions, and liquid metals.

 

          Liquids, gas mixtures, and liquids containing suspended solids can also be transported. The technical parameters of the pump performance include flow, suction stroke, lift, shaft power, water power, efficiency, etc. According to different working principles, it can be divided into volume pump, vane pump and other types. Volumetric pumps use their studio volume changes to transfer energy; vane pumps use rotary blades to interact with water to transfer energy, including centrifugal pumps, axial pumps, and mixed-flow pumps.
