In the chemical and petroleum sectors, raw materials, semi-finished products and finished products are mostly liquids, and the preparation of raw materials into semi-finished and finished products requires a complicated process in which the pump acts as a pressure source for transporting liquids and providing chemical reactions. In addition, in many devices, pumps are also used to regulate the temperature.
In agricultural production, pumps are the main irrigation and drainage machinery. China's rural areas are vast, and every year, a large number of pumps are needed in rural areas. Generally, agricultural pumps account for more than half of the total pump output.
Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to use pump drainage. In the process of mineral processing, smelting and rolling, pumps are needed to supply water.
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, oil and gas mixed pumps, circulating pumps, and ash pumps.
In the construction of national defense, the adjustment of aircraft flaps, rudders and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines require pumps. High pressure and radioactive liquids, and some require pumps without any leakage.
In short, whether it's airplanes, rockets, tanks, submarines, or drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are everywhere. That's it, so the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
Electric pump, that is, an electric drive pump. The electric pump is composed of a pump body, a water pipe, a pump base, a submersible motor (including a cable), and a starter protection device. The pump body is the working part of the submersible pump. It consists of inlet pipe, diversion shell, check valve, pump shaft and impeller. There are two ways to fix the impeller on the shaft.
