An Introduction to Vacuum Pumps
With the development of vacuum applications, many types of vacuum pumps have been developed in recent years. As the requirements of vacuum technology in the field of production and scientific research for its application pressure are getting wider and wider, most of them need to be composed of several vacuum pumps to form a vacuum pumping system to jointly pump to meet the requirements of production and scientific research processes. For the convenience of use and the needs of various vacuum processes, sometimes various vacuum pumps are combined according to their performance requirements and applied in the form of a unit.
What is the function of vacuum pump
The function of a vacuum pump is to continuously extract the non-condensable gas and the leaked air from the condenser to maintain the condenser vacuum. Vacuum pump can evacuate the container to obtain and maintain the vacuum through mechanical, physical, chemical, physical chemistry and other methods.
How vacuum pump works
According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas capture pumps and gas transfer pumps. Gas trapping pump reduces the number of gas molecules in the container to achieve the purpose of pumping through gas molecules that are adsorbed or condensed on the inner surface of the pump. Gas transfer pump achieves the purpose of pumping through gas that can continuously suck and discharge gas.

Where are vacuum pumps used
A vacuum pump can be widely used in pharmaceutical, chemical, vacuum coating, vacuum drying, surface treatment, vacuum smelting, bricks, ceramics manufacturing, food packaging, milking, beverage industry and so on, which uses mechanical, physical, chemical, physical chemistry and other methods.
The function of the vacuum pump is to remove gas molecules from the vacuum chamber, in order to reduce the gas pressure in the vacuum chamber, and make it reach the required vacuum degree. Therefore, a vacuum pump plays an essential role in these fields.
What is the function of vacuum pump
Vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to evacuate the pumped container to obtain a vacuum. A vacuum pump is a device that uses various methods to improve, generate, and maintain a vacuum in a sealed space.
Vacuum pumps can be used in pharmaceutical and chemical industries, vacuum coating, vacuum drying, surface treatment, vacuum smelting, brick, ceramic manufacturing, food packaging, milking, beverage industry and so on. The role of the vacuum pump is to remove gas molecules from the vacuum chamber, reduce the gas pressure in the vacuum chamber, and help to reach the required vacuum degree.
Why does a vacuum pump need oil
Vacuum pump oil is a kind of lubricating oil specially developed for vacuum pumps on vacuum equipment, which is divided into mineral oil and synthetic oil.Vacuum pump oil is suitable for reciprocating booster pumps, mechanical booster pumps and oil-sealed mechanical vacuum pumps. It can also be used for various diffusion vacuum pumps. It is recommended for vacuum pumps in the fields of crafts, ceramics, chemistry, etc.
The type of vacuum pumps
Vacuum pumps can be divided into dry screw vacuum pumps, water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, roots pumps, and diffusion pumps and so on. These pumps are indispensable main pumps in the vacuum process of various industries.
