In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products and products are liquids, and the production of semi-finished products and products from raw materials requires complex technological processes. Pumps play the role of conveying liquids and providing pressure and flow for chemical reactions in these processes. In addition, pumps are used in many equipment to regulate temperature.
In agricultural production, pumps are the main irrigation and drainage machinery. Our country has a broad rural territory, and many pumps are needed every year. Generally speaking, agricultural pumps account for more than half of the total pump output.
In the mining and metallurgical industries, pumps are also widely used equipment. The mine needs pumps for drainage, and pumps are needed for water supply during beneficiation, exercise and rolling.
In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, tertiary pumps, and many boiler feed pumps, condensate pumps, oil and gas multiphase pumps, circulating pumps, ash pumps, etc. required by thermal power plants.
In national defense construction, pumps are required for the dispatch of aircraft flaps, tail rudders and landing gears, the rolling of warships and tank turrets, and the sinking and floating of submarines. High pressure and radioactive liquid, some also require the pump to be free of any leakage, etc.
In a word, whether it is aircraft, rockets, tanks, submarines, or drilling, mining, trains, ships, or daily life, pumps are needed everywhere, and (Alfa Laval pumps) are running everywhere. That is why pumps are listed as general machinery, which is a major product in the machinery industry.
Alfa Laval , This is an electrically driven pump. The electric pump is composed of pump body, lifting pipe, pump base, submersible motor (including cable) and starting protection equipment. The pump body is the operating part of the submersible pump, which is composed of water inlet pipe, guide shell, check valve, pump shaft, impeller and other parts. There are two ways to fix the impeller on the shaft.
