ADDRESS:No.9th Xiajiahe Industrial Park, Ganjingzi District, Dalian, China
In the production of the chemical and petroleum sectors, raw materials, semi-finished products and finished products are mostly liquid, and raw materials into semi-finished products and finished products, need to undergo a complex process, the pump in these processes played a liquid and provide a chemical reaction of the pressure flow of the role, in addition, in many devices also use the pump to adjust the temperature.
In agricultural production, the pump is the main irrigation and drainage machinery. China's vast rural areas, each year the rural needs a large number of pumps, generally speaking, agricultural pumps accounted for more than half the total pump.
In the mining and metallurgical industries, pumps are also the most used equipment. The mine needs to use the pump drainage, in the processing, the smelting and the rolling process, need the pump to supply water and so on.
In the power sector, nuclear power plants need core pumps, two-level pumps, three-level pumps, cogeneration plants require a large number of boiler feedwater pumps, condensate pumps, oil and gas mixed transmission pumps, circulating water pumps and ash pump and so on.
In the National defense construction, the aircraft flaps, the rudder and the landing gear adjustment, the warship and the tank turret rotation, the submarine's ups and downs and so on need to use the pump. High pressure and radioactive liquid, some also require no leakage of the pump and so on.
In short, whether it is aircraft, rockets, tanks, submarines, or drilling, mining, trains, ships, or daily life, everywhere need to pump, there are pumps running everywhere. This is the case, so the pump as a general machinery, it is the mechanical industry in a class of major products.
Electric pump, that is, electricity-driven pump. The electric pump is composed of a pump body, a riser, a pump seat, a submersible motor (including a cable) and a starter protection device. The pump body is the working part of the submersible pump, which consists of the inlet pipe, the diversion shell, the reversing valve, the pump shaft and the impeller. There are two ways of fixing the impeller on the shaft.
