17、 Rotary vane vacuum pump

The rotary vane of the rotary vane pump divides the crescent shaped space enclosed by the rotor, pump chamber, and two end caps into three parts: A, B, and C.

Performance characteristics:

Rotary vane vacuum pump (referred to as rotary vane pump) is a type of oil sealed mechanical vacuum pump. Its working pressure range is 101325~1.33 × 10-2 (Pa), which belongs to low vacuum pumps. It can be used alone or as a pre pump for other high vacuum pumps or ultra-high vacuum pumps. It has been widely used in production and scientific research departments such as metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum, and medicine.

1. Small size, light weight, and low noise; 2. Equipped with a gas damper that can extract a small amount of water vapor; Long term continuous operation is allowed under the condition that the inlet pressure is less than 1.3X103 Pa within the ambient temperature range of 5 ° C to 40 ° C. When the relative humidity of the extracted gas is greater than 90%, the gas damper should be opened. 3. Equipped with an automatic anti backflow check valve, easy to start; 4. The continuous and unobstructed air intake shall not exceed one minute of atmospheric operation; 5. Not suitable for extracting gases that corrode metals, react chemically with pump oil, contain particulate dust, as well as gases with high oxygen content, explosive, and toxic substances.
