Features and typical uses of oil-sealed rotary vane vacuum pumps

The rotor mounted eccentrically in the rotary vane vacuum pump pump is tangent to the fixed surface of the stator, and two (or more) rotary vanes slide (usually radial) in the rotor groove and come into contact with the inner wall of the stator, dividing the pump chamber into several variable volumes of a rotating variable volume vacuum pump. Usually, the gap between the rotary vane and the pump cavity is sealed with oil, so the rotary vane vacuum pump is generally an oil-sealed mechanical vacuum pump.
Oil-sealed rotary vane vacuum pump is divided into single-stage pump and double-stage pump, which is widely used in the industrial field and belongs to one of the basic pumps. It can be used alone or as a backing pump or pre-pumping pump for other high vacuum pumps or ultra high vacuum pumps.

Oil-sealed rotary vane pumps are used in a wide range of applications and are available in almost all industrial sectors. Chinese Hokaido rotary vane pump has the characteristics of low cost, low noise, easy maintenance, strong applicability and more energy-saving lamp. Clean dry air without other mixtures at room temperature can be extracted, but it cannot be extracted from explosive with excessive oxygen, corrosive to metal, chemical reaction to vacuum pump oil, and particles, dust, and cannot be used as a delivery pump and compression pump.
The main uses of oil rotary vane pumps are metallurgy, machinery, military, electronics, chemical, light industry, petroleum and medicine and other production and scientific research fields.

Applications in the field of new energy solar energy
Oil rotary vane pumps can be used in the entire automation process chain of the solar industry, including monocrystalline silicon, polysilicon production furnaces, Taineng you panel cutting, solar vacuum lamination, etc.

Applications in fine chemicals
Oil rotary vane vacuum pumps can be used in fine chemicals such as vacuum filtration, vacuum evaporation, vacuum distillation, vacuum impregnation, vacuum drying and so on.
Applications in the petroleum sector
Used in oil extraction/transportation/oilfield water injection systems, as well as in leaching negative pressure evaporation and oil and gas recovery processes.

Applications in the food industry
Can be used for sausages, ham to provide vacuum packaging and drying; It is used for the humidification of tobacco, the vacuum dehydration of dried vegetables and fruits, and the sterilization of special foods.
