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 is less than tens of milliliters per hour; the pressure of the pump can range from normal pressure to as high as 19.61Mpa (200kgf/hour). cm2) or above; the temperature of the liquid to be transported is below -200 degrees Celsius, and the highest is above 800 degrees Celsius. There are many kinds of liquids transported by pumps, such as transporting water (clean water, sewage, etc.), oil, acid and alkali, suspension, and liquid metal.
1). In the mining and metallurgical industries, pumps are also the most used equipment. The mine needs to be drained by a pump. In the process of beneficiation, smelting and rolling, it is necessary to use a pump to supply water first.
2). In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, circulating pumps, and ash pumps.
3). In national defense construction, the adjustment of aircraft flaps, tail rudders and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
4). In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total pump output.
5). In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products and finished products are liquids, and the production of semi-finished products and finished products from raw materials needs to go through complex technological processes. In addition, in many installations, pumps are used to regulate temperature.
6). In the shipbuilding industry, there are generally more than 100 pumps used on each ocean-going ship, and their types are also various. Others, such as water supply and drainage in cities, water for steam locomotives, lubrication and cooling in machine tools, conveying bleach and dyes in the textile industry, conveying pulp in the paper industry, and conveying milk and sugar foods in the food industry, all require a large amount of water. of the pump.
