In the production of chemical and petroleum sectors, raw materials, semi-finished products and finished products are mostly liquid, and the process of making raw materials into semi-finished products and finished products requires a complex process. Electric pumps play a role in conveying liquid and providing pressure and flow of chemical reaction in these processes. In addition, electric pumps are also used to regulate temperature in many devices.
In agricultural production, electric pump is the main drainage and irrigation machinery. China's rural area is vast, and every year a large number of pumps are needed in rural areas. Generally speaking, agricultural pumps account for more than half of the total output of pumps.
In the mining and metallurgical industries, electric pumps are also the most used equipment. Mines need to use pumps to drain water. In the process of mineral processing, smelting and rolling, pumps are needed to supply water.
In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, tertiary pumps, thermal power plants need a large number of boiler feed water pumps, condensate water pumps, oil and gas mixing pumps, circulating water pumps and ash pump.
In national defense construction, the adjustment of aircraft flaps, tail rudder and landing gear, the rotation of warships and tank turrets, and the sinking and floating of submarines all need pumps. High pressure and radioactive liquids, some also require no leakage of pumps, etc.
In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or daily life, there is a need for electric pumps everywhere, pumps are running everywhere. That's why pumps are listed as general machinery, which is one of the main products in machinery industry.
