Pump is pronounced bēng in pinyin.
1. Definition and Classification of Pumps
A pump is a device capable of conveying fluids from a low-pressure region to a high-pressure region. It uses energy input through mechanical or physical means to generate pressure in a liquid or gas, thus realizing functions such as conveying, circulating or pressurizing. According to different working mediums and working principles, pumps can be divided into many different types, such as centrifugal pumps, displacement pumps, gear pumps and so on.
2, the working principle of the pump
The working principle of the pump mainly relies on the movement of the rotor blade, plunger, screw and other structures to realize. Take centrifugal pump as an example, when the motor or engine of the pump drives the rotor to rotate, the liquid enters the pump from the suction port and is pushed by the rotating impeller.
Under centrifugal force, the liquid is rapidly thrown out and generates high pressure, which is then output through the outlet pipe. Other types of pumps have a similar working principle, just with different structures and movements.
3, the application of the pump
The pump has a wide range of applications in many fields. In the industrial field, pumps are often used to handle a variety of liquids, such as water, oil, chemical solutions. They play a vital role in liquid transportation, circulation cooling, pressure increase and chemical processes.
In the construction field, pumps are used in water supply and drainage systems, such as feed pumps and drainage pumps. In addition, pumps are widely used in agricultural irrigation, mine drainage, medical equipment, marine engineering and other fields.
4, pump selection and maintenance
Selecting the right pump is very important for efficiency and equipment life. In the selection, need to consider the flow rate, head, media characteristics, working environment and other factors. Different working conditions have different performance requirements for pumps, so they need to be selected reasonably according to actual needs. In addition, regular maintenance and repair of the pump can extend its service life, such as checking seals, lubricating parts, cleaning components.
In summary, the pump is a device used to transport fluids, through the movement of the rotor blades or other structures to generate pressure, to achieve the transfer of fluids, circulation or pressurization and other functions. There are many types of pumps, which are categorized according to the working principle and the nature of the medium.
Pumps in industry, construction, agriculture and other fields have a wide range of applications. In the selection and use of the process, you need to consider a variety of factors and reasonable selection and maintenance, in order to improve efficiency and equipment life.
