Five minutes to show you the pump

What is a pump? Often encounter such customers, know that they are to buy a pump, but even what the pump is, the specific why it is used, and what kind of pump they want are confused. So today, let’s talk about it.

5 minutes to meet the pump! A simple definition that tells you what is a pump

Conceptually, a pump is actually a machine used to increase the pressure of a liquid or gas to transport the flow, or it can be said to be a device used to move a liquid, gas or special fluid medium, that is, a machine that does work on the fluid. It transfers the mechanical energy or other external energy of the prime mover to the liquid, making the liquid energy increase. The pump is mainly used to transport liquids including water, oil, acid lye, emulsion, suspension emulsion and liquid metal, etc., and can also transport liquids, gas mixtures and liquids containing suspended solids.

So, in life, how to reflect the specific use of the pump?

Farmland irrigation, petrochemical industry, power industry, urban water supply and drainage, mining and shipbuilding industry, nuclear power generation, water jet propulsion of ships, fuel supply of rockets, etc. What, then, explains these uses? Now, let’s take a look!

Use 1: chemical and petroleum production

Chemical and petroleum production sites, the raw materials, semi-finished products and finished products are mostly liquid, and the raw materials into semi-finished products and finished products, need to go through a complex process. Then at this time, the role of the pump is reflected, at this time, the pump can optimize the process and simplify it by conveying the liquid and providing the pressure flow of the chemical reaction. Especially at present, the country pays more attention to the environment, and the requirements for pump products in these areas are also getting higher and higher.

Use 2: agricultural irrigation

China’s rural area is vast, some areas dry and less rain, need artificial irrigation to maintain the smooth development of agriculture. To this end, a large number of pumps are needed in rural areas every year, and agricultural pumps generally account for more than half of the total output of pumps.

Use 3: Mining and metallurgical industry

Pumps are also used a lot of equipment. The mine needs to be drained with pumps, and in the process of mineral processing, smelting and rolling, pumps are required to supply water first.

Use 4: Power applications

Nuclear power plants need nuclear main pumps, secondary pumps, tertiary pumps, thermal power plants need a large number of boiler feed pumps, condensate pumps, circulating pumps and ash and slag pumps.

Use five: national defense construction

The adjustment of aircraft flaps, tail rudder and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all need pumps. High pressure and radioactive liquids, some also require the pump without any leakage.

Use six: shipbuilding

The pumps used on each ocean ship are generally more than one hundred, and their types are also various. Others, such as water supply and drainage in cities, water for steam locomotives, lubrication and cooling in machine tools, conveying bleach and dye in the textile industry, conveying pulp in the paper industry, and conveying milk and sugary foods in the food industry, require a large number of pumps.

Today, the use of pumps is becoming more and more widespread, stemming from the governance of the environment, and the requirements for pumps are becoming higher and higher. As far as China is concerned, there are strict indicators for flow, head, shaft power, speed, allowable suction vacuum height, specific speed, etc.
