Application of Pumps in Various Areas
From the performance range of the pump, the flow rate of the giant pump can reach more than hundreds of thousands of cubic meters per hour, while the flow rate of the micro-pump can be less than tens of milliliters per hour; the pressure of the pump can be up to 19.61 Mpa (200 kgf/cm2) from normal pressure; the temperature of the liquid being transported can be as low as - 200 degrees Celsius and as high as 800 degrees Celsius. There are many kinds of pumps to transport liquids, such as water (clean water, sewage, etc.), oil, acid and alkali liquids, suspensions, and liquid metals.
In the production of chemical and petroleum sectors, raw materials, semi-finished products and finished products are mostly liquid, and the process of making semi-finished products and finished products from raw materials needs to go through complex processes, in which pumps play the role of transporting liquids and providing pressure and flow of chemical reactions. In addition, pumps are used to regulate temperature in many devices.
In agricultural production, pumps are 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, 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 first.
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, circulating water pumps and ash slag pumps.
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 the shipbuilding industry, more than 100 pumps are used on each ocean-going ship, and the types of pumps are also various. Others, such as water supply and drainage in cities, water for steam locomotives, lubrication and cooling in machine tools, transportation of bleaching and dyes in textile industry, pulp in paper industry, and milk and sugar food in food industry, need a large number of pumps.
In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or daily life, pumps are needed everywhere, and pumps are running everywhere. It is precisely this, so the pump as a general purpose machinery, it is a kind of machinery industry in the important products of students.
