The single-stage oil rotary vane vacuum pump is an oil-sealed mechanical vacuum pump. Its working pressure range is usually 101325~1.33×10^-2 (Pa), which belongs to the category of low vacuum pump. The pump has the characteristics of low cost, low noise, easy maintenance, strong applicability and energy saving, and is widely used in many fields. The following are the main application areas of Leno single-stage oil rotary vane vacuum pump:

Industrial production:

■ Metallurgy: In the metallurgical industry, single-stage oil vane vacuum pumps can be used for various smelting and vacuum treatment processes.

■ Machinery: In the field of machinery manufacturing, the pump can be used for vacuum holding, vacuum clamping and other processes.

■ Electronics: In the electronics industry, single-stage oil vane vacuum pumps can be used for semiconductor manufacturing, vacuum coating and other processes.

■ Chemical industry: In the field of fine chemicals, the pump can be used for vacuum filtration, vacuum evaporation, vacuum distillation, vacuum impregnation, vacuum drying and other processes.

■ Light industry: In light industries such as food packaging and tobacco processing, the pump can be used for vacuum packaging, vacuum suction and other processes.

■ Petroleum: In oil extraction, transportation and oil field water injection systems, as well as in the process of leaching negative pressure evaporation and oil and gas recovery, single-stage oil vane vacuum pumps also have important applications.

Research fields:

In scientific research departments, single-stage oil rotary vane vacuum pumps are often used in various vacuum experiments and tests to provide the required vacuum environment.

Other applications:

■ Solar industry: In the solar industry, the pump can be used in automated process chains such as monocrystalline silicon, polycrystalline silicon production furnaces, solar panel cutting, solar vacuum lamination, etc.

■ Food industry: In the food industry, single-stage oil-filled rotary vane vacuum pumps can be used for vacuum packaging and drying of products such as sausages and ham, as well as humidification of tobacco, vacuum dehydration of dried fruits and vegetables, and sterilization of special foods.

It should be noted that although the single-stage oil rotary vane vacuum pump is widely used, it also has its limitations. For example, it cannot extract gases with high oxygen content, gases that are corrosive to metals, gases that react chemically to pump oil, and gases that contain particulate dust. In addition, the pump cannot be used as a delivery pump or a compression pump.

Single-stage oil rotary vane vacuum pump plays an important role in industrial production, scientific research and many other industries due to its unique performance and wide application areas.
