Performance range from the pump to see giant pump flow up to hundreds of thousands of cubic meters per hour, while the micro pump flow per hour in a few milliliters; pump from atmospheric pressure up to 19.61Mpa (200kgf/cm2); the lowest temperature of the liquid is transported up to -200 degrees Celsius, up to 800 degrees celsius. There are many kinds of pumps, such as transportation of water (water, sewage, etc.), oil, acid and alkali, suspension, and liquid metals.
In the chemical and oil sector production, raw materials, semi-finished products and finished products are mostly liquid, and semi-finished and finished products to raw materials, need to go through a complex process, to pump and provide transportation of liquid chemical reaction of the pressure and flow in the process, in addition, the device also used in many pumps to adjust the temperature.
In agricultural production, the pump is the main irrigation and drainage machinery. China's vast rural areas, a large number of rural areas each year needs a pump, generally accounted for more than half of the total output of agricultural pumps.
Pumps are also the most used equipment in the mining and metallurgical industries. Mine need to use pump drainage, in the mineral processing, smelting and rolling process, the need to pump water, etc..
In the power sector, nuclear power plants need nuclear main pump, two pumps, three pumps, thermal power plants require large amounts of boiler feed pumps, condensate pumps, circulating pumps and ash pump etc..
In national defense construction, aircraft flap, rudder and landing gear of the adjustment, warships and tanks turret rotation, the submarine's ups and downs and so need to pump. High pressure and radioactive liquid, and some even seek the pump without any leakage, etc..
In the shipbuilding industry, each ocean going round on the pump used in more than one hundred units, the type is also a wide range of. As the city water supply and drainage, water steam locomotive, machine tool lubrication and cooling, the textile industry in the transmission fluid and dye bleaching, pulp paper industry in the transportation and food industry in the transportation of milk and sugar foods, we need to have a lot of pump.
In short, whether it is aircraft, rockets, tanks, submarines, or drilling, mining, trains, ships, or everyday life, everywhere need to use the pump, running everywhere. It is this way, so the pump as general machinery, it is a kind of mechanical industry in the production of products.
