Pumps in various fields

Judging from the performance range of the pump, the flow of the huge pump can reach hundreds of thousands of cubic meters per hour, while the flow rate of the micropump is less than tens of milliliters per hour; the pressure of the pump can range from atmospheric pressure to as high as 19.61Mpa (200kgf/ Cm2) Above; The temperature of the liquid to be transported is as low as -200 degrees Celsius or below and up to 800 degrees Celsius or more. The pump transports a wide variety of liquids, such as transport water (clean water, sewage, etc.), oil, acid, alkali, suspension, and liquid metal.

In the chemical and petroleum sector, raw materials, semi-finished products, and finished products are mostly liquids, and the production of semi-finished and finished products from raw materials requires a complicated process in which the pumps act as pressure fluids for transporting liquids and providing chemical reactions. In addition, pumps are used to adjust the temperature in many devices.

In agricultural production, pumps are the main drainage and irrigation machinery. China's rural areas are vast, and a large number of pumps are needed every year in rural areas. In general, agricultural pumps account for more than half of the total output of pumps.

Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to use a pump to drain water. In the process of beneficiation, smelting and rolling, it is necessary to use a pump to supply water first.

In the power sector, nuclear power plants require nuclear main pumps, secondary pumps, tertiary pumps, and thermal power plants that require a large number of boiler feed pumps, condensate pumps, circulating water pumps, and ash slag pumps.

In national defense construction, the use of pumps is required for the adjustment of aircraft flaps, rudder and landing gear, the rotation of warships and tank turrets, and the subsidence of submarines. High pressure and radioactive liquids, and some also require no leakage from the pump.

In the shipbuilding industry, the number of pumps used on each ocean-going wheel is generally more than one hundred, and its type is also varied. Others such as water supply and drainage in cities, water for steam locomotives, lubrication and cooling in machine tools, transport of bleaching fluids and dyes in the textile industry, transport of pulp in the paper industry, and transport of milk and sugar foods in the food industry The pump.

In short, whether it is an aircraft, a rocket, a tank, a submarine, or a well, a mining, a train, a ship, or a daily life, pumps are needed everywhere, and pumps are everywhere. It is this way that the pump is classified as a general-purpose machine, which is a type of raw product in the machinery industry.
