I. Overview of XD Series Single-Stage Rotary Vane Vacuum Pump

The XD series single-stage rotary vane vacuum pump is a single-stage coupling structure. Its working performance features high speed, low noise, fast pumping speed, high efficiency. The pump only needs air cooling, has an anti-oil return structure to prevent pump oil from flowing back into the evacuated system. The pump is equipped with an exhaust filter to effectively eliminate oil mist. It operates smoothly with low vibration and can work under any pressure. Technical parameter 2×10-2. It is widely used in food vacuum packaging, medicine, paper conveying in printing machinery, glass industry conveying, vacuum fixtures, drying and other units. It cannot pump flammable, explosive, high oxygen content, or corrosive gases. If continuous long-time operation at higher inlet pressure is required, please specify when ordering.

II. Working Principle of XD Series Single-Stage Rotary Vane Vacuum Pump

The single-stage rotary vane vacuum pump is a basic equipment for obtaining vacuum. It has a rotor eccentrically installed in the pump body and tangent to the inner surface of the pump body. There are three vanes that can slide radially in the rotor slots. When the rotor rotates, centrifugal force keeps the vanes in contact with the inner wall of the pump body. The vanes divide the pump chamber into three working chambers with periodically changing volumes. The periodic change of the working chamber volume enables the pump to complete suction and exhaust. Each revolution, the pump removes a portion of the gas from the container until the ultimate pressure of the vacuum pump is reached.

III. Features of XD Series Single-Stage Rotary Vane Vacuum Pump

1. Direct drive mechanism, compact structure, light weight.

2. Air cooling, no water needed, easy operation, low maintenance cost.

3. Multiple vanes and rubber pads at the bottom ensure stable operation and low vibration.

4. The pump is equipped with an oil-gas separator to effectively eliminate tiny oil mist in the exhaust.

5. The pump is designed with an automatic oil circulation system, no frequent oiling needed.

6. The pump is equipped with an automatic suction valve. When the pump stops working, the suction valve automatically isolates the pump from the evacuated system to prevent pump oil from flowing back.

7. High pumping efficiency, still high pumping speed when inlet pressure approaches ultimate pressure.

8. Can work in a wide inlet pressure range of 105~102pa.
