Water pump is a machine that transports liquid or pressurizes it. It will be the prime mover mechanical energy or other external energy transfer to the liquid, so that the liquid energy increase,mainly used to transport liquids including water, oil, acid lye, emulsion, suspension emulsion and liquid metal, etc.
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.
The main types of water pumps are: QJ, QJD series deep well submersible pump, QGD series stainless steel screw pump, QDX, QX series submersible pump, WQ series submersible sewage pump, Jet pump.
