Overview of the pump
Pump is to transport liquid or liquid pressurized machinery.
Transfer mechanical energy or other external energy to the liquid will prime mover, the liquid energy increases.

Pump is mainly used to transport water, oil, acid liquid, emulsion, suspension liquid emulsions and liquid metals, but also transport liquid, gas and liquid mixture containing suspended solids. 

Pumps are usually divided according to the principle of positive displacement pumps, power pumps and other types of pump categories. Except works classification, but also by other methods of classification and nomenclature.

For example, the method can be divided by driving an electric pump and turbine pump, etc; according to the structure can be divided into single-stage pumps and multi-stage pumps; use can be divided into the boiler feed pumps and metering pumps, etc; according to the nature of transmission fluid can be divided water pump, oil pump and mud pump. According to whether the shaft structure, can be divided into linear pumps, and traditional pumps.

In the chemical and oil sector production, raw materials, semi-finished and finished products are mostly liquid, semi-finished products and raw materials and finished products will need to go through a complex process, played a transmission fluid pump and pressure flow to provide a chemical reaction in these processes the role, in addition, also used in many devices to adjust the pump temperature.

In agricultural production, the pump is the main irrigation machinery. Our vast rural areas, rural areas each year require a lot of pumps, agricultural pumps generally accounted for more than half of the total output of the pump.

In the mining and metallurgical industry, the pump is the most used devices. Need to pump mine drainage, beneficiation, smelting and rolling process, needed to pump water supply.


In the electricity sector, nuclear power plants need nuclear main pump, two pumps, three pumps, thermal power plants require a lot of boiler feed pumps, condensate pumps, circulating pumps and ash pumps.

In defense construction, aircraft flaps, rudder and landing gear adjustment, warships and tanks turret rotation, ups and downs and so need submarine pump. High pressure and radioactive liquid, and some also require a pump without any leakage.

In short, whether it is aircraft, rockets, tanks, submarines, or drilling, mining, trains, ships, or daily life, everywhere need to use a pump, the pump is running everywhere. It is so, so the pump as general machinery, the machinery industry which is a major product category.
