What is the pump for?
- Nov 04, 2017 -

Definition 1: change the volume of fluid pressure or fluid conveying machine. Applied disciplines: Mechanical Engineering (first level discipline); transmission (two level discipline); hydraulic transmission (grade three discipline) definition 2: membrane penetrating protein with ATP enzyme activity. It is possible to transport ions or small molecules by reverse electrochemical gradients through the energy produced by hydrolysis of ATP. Subject: application of cell biology (a subject); cell physiology (two subjects)


Pump is mainly used to transport liquid, including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, etc., also can transport liquid, gas mixture and liquid containing suspended solids.


Performance range from the pump to see giant pump flow up to hundreds of thousands of cubic meters per hour, while the micro pump flow per hour in a few milliliters; pump from atmospheric pressure up to 19.61Mpa (200kgf/cm2); the lowest temperature of the liquid is transported up to -200 DEG C, up to 800 DEG C. There are many kinds of pumps, such as transporting water (clean water, sewage, etc.), oil, acid and alkali liquid, suspension, liquid metal and so on.

Electromechanical integrated pump in chemical and oil sector production, raw materials, semi-finished products and finished products are mostly liquid, and semi-finished and finished products to raw materials, need to go through a complex process, to pump and provide transportation of liquid chemical reaction of the pressure and flow in the process, in addition, in many devices used to regulate the temperature of pump.

In agricultural production, the pump is the main irrigation and drainage machinery. Rural areas in our country are vast, and each year a large number of pumps are needed in rural areas. Generally speaking, agricultural pumps account for more than half of the total output of pumps.

In the mining and metallurgical industry, the pump is the most used equipment. The mine needs to pump water, in the ore dressing, smelting and rolling process, need to pump to water supply, etc..

In the power sector, nuclear power plants need nuclear pumps, two pumps, three pumps, thermal power plants, a large number of boiler feed pumps, condensate pumps, circulating pumps and ash pumps, etc..

In national defense construction, aircraft flaps, tail rudder and landing gear adjustment, warships and tank turret rotation, submarine ups and downs and so on, need to use the pump. High pressure and radioactive liquid, and some also called pump without any leakage.

In the shipbuilding industry, the pump used on each oceangoing wheel is generally more than 100, and its types are various. As the city water supply and drainage, water steam locomotive, machine tool lubrication and cooling, the textile industry in the transmission fluid and dye bleaching, pulp paper industry in the transportation and food industry in the transportation of milk and sugar foods, we need to have a lot of pump.

In a word, whether planes, rockets, tanks, submarines, or drilling, mining, trains, ships, or daily life, pumps are everywhere, and pumps are running everywhere. It is so, so the pump as a general machine, it is a kind of machinery industry in the main products.
