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, increasing the energy of the liquid, mainly for transporting liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal.

Liquids, gas mixtures, and liquids containing suspended solids can also be delivered. 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 so on. The volumetric pump uses its change in the volume of the working chamber to transfer energy; the vane pump uses the interaction of the rotating blades with water to transfer energy, such as centrifugal pumps, axial pumps and mixed flow pumps.

1. Positive displacement pump: The liquid is delivered by the change of the working chamber volume period.

2, vane pump: the use of blade and liquid interaction to transport liquid.

Energy conservation and emission reduction have become the primary content of China's economic development planning plan. In particular, we have put forward more stringent emission reduction policies for high energy consumption in industries such as electricity, steel, nonferrous metals, petrochemicals and water treatment. Pumps, as the industrial center fluid transport equipment, have the most important energy consumption, and have become the primary issue for energy-saving operations.


The most common drive for pumps is driven by an electric motor. The first step in the pump's energy saving is to operate the pump unit (pump, prime mover and some of the shifts) at the highest power, so that the power input from the outside world is reduced to the lowest point. The energy saving of the pump enables comprehensive skills, which touch the pump's own energy saving, system energy saving and operation and operation.
