The rotary vane pump is a two-stage structure consisting of a high-pressure stage and a low-pressure stage. Its suction port is connected to a vacuum container or vacuum equipment, and during operation, a large amount of gas inside the container is sucked in and discharged. When the equipment obtains vacuum, the high-pressure stage exhaust valve plate will be closed, and the gas sucked in by the high-pressure stage will be transferred to the second stage and sucked in and discharged through the second stage, so that the vacuum equipment can obtain a certain vacuum. This pump can be widely used in vacuum smelting, vacuum welding, vacuum impregnation, vacuum coating, vacuum heat treatment, vacuum drying, vacuum packaging and other industrial processes such as refrigerators, air conditioners, light bulbs, fluorescent lamps, bottle liners, electronics, metallurgy, medicine, chemical industry, oil filters, printing machinery, packaging machines, etc. It can be used as a front-end pump for diffusion pumps, Roots pumps, molecular pumps, etc., for supporting electronic instruments, medical instruments, and experimental research applications.

What are the advantages of rotary vane pumps?

1. The export oil mist filter is a standard configuration, with a rotary vane pump for oil circulation, no oil fumes, clean, environmentally friendly, and fuel-efficient.

2. It can work continuously at an inlet pressure of atmospheric pressure.

3. Air cooling, no need for water cooling, economical and convenient.

4. Can maintain high pumping speed even under low pressure.

5. Built in automatic anti backflow valve.

6. It can be used in conjunction with various accessories, thus meeting the needs of different applications.

7. Compact structure, small size, space saving.

8. Low noise, low vibration.

9. Strong ability to eliminate water vapor.
