The circulating water vacuum pump is a vacuum equipment that operates based on the principle of water circulation, which achieves the process of air extraction and exhaust through the circulating flow of water. This article will introduce the working principle, main characteristics, and applications in various fields of circulating water vacuum pumps.

The circulating water vacuum pump utilizes the circulating flow of water to achieve the process of vacuum pumping and exhaust. It consists of a water ring and an impeller. When the water ring rotates, the impeller will pump gas into the pump through centrifugal force, and then mix the gas with water and discharge it out of the pump. By continuously flowing circulating water, a stable vacuum environment is achieved.

The circulating water vacuum pump has high pumping speed and efficiency, and can quickly achieve vacuum extraction; Adopting the principle of water circulation, it does not require the use of oil or other lubricating materials, avoiding pollution and emissions, and has the advantage of energy conservation; The noise generated during the operation of the circulating water vacuum pump is relatively low, which has little impact on the working environment and operators. It can also maintain a relatively stable vacuum degree during the pumping process, and has high work stability and reliability.

Circulating water vacuum pumps are often used in laboratory experiments such as vacuum extraction, rotary evaporation, and freeze-drying; It plays a key role in Vacuum distillation, extraction, drying and other processes in the chemical industry; Widely used in vacuum drying, concentration, freeze-drying and other steps in the pharmaceutical process; Circulating water vacuum pumps are often used in fields such as environmental monitoring, gas sampling, and gas chromatography.

Circulating water vacuum pump, with its advantages of high pumping efficiency and energy conservation, has become an ideal choice for vacuum treatment in various industries. Its stability and reliability have made it widely used in fields such as laboratory research, industrial manufacturing, and environmental protection, making important contributions to the development and progress of related fields.
