What are the application fields of pumps

In the production of the chemical and petroleum sectors, raw materials, semi-finished products, and finished goods are mostly liquids. The conversion of raw materials into semi-finished and finished products involves complex technological processes. Pumps play a crucial role in these processes, serving to transport liquids and provide pressure flow for chemical reactions. Additionally, pumps are also used in many devices to regulate temperature.

In agricultural production, pumps are the primary irrigation and drainage machinery. China's vast rural areas require a large number of pumps every year, and agricultural pumps generally account for more than half of the total pump production.

In the mining and metallurgical industries, pumps are also the most commonly used equipment. Mines require pumps for drainage, and pumps are needed for water supply during mineral processing, smelting, and rolling processes.

In the power sector, nuclear power plants require nuclear main pumps, secondary pumps, and tertiary pumps, while thermal power plants need a large number of boiler feed pumps, condensate pumps, oil-gas mixed flow pumps, circulating water pumps, ash pumps, and so on.

In national defense construction, pumps are necessary for various applications such as adjusting aircraft flaps, tail rudders, and landing gear, rotating the turrets of warships and tanks, and controlling the buoyancy of submarines. For handling high-pressure and radioactive liquids, it is also required that the pumps exhibit zero leakage.

In summary, pumps are essential in various fields, including aviation, rocketry, tank operations, submarine activities, drilling, mining, railway transportation, shipping, and even daily life. They are operational everywhere. It is precisely for this reason that pumps are classified as general-purpose machinery, which constitutes a major category of products in the machinery industry.

An electric pump, which is driven by electricity, consists of a pump body, a lifting pipe, a pump base, a submersible motor (including cables), and a starting protection device. The pump body, the working component of the submersible pump, is composed of inlet pipes, a diffuser shell, a check valve, a pump shaft, and an impeller. There are two ways to fix the impeller on the shaft.
