Introduction to Puxu Vacuum Pump Germany Puxu R5/RA series vacuum pump is a single-stage rotary vane oil-sealed vacuum pump, which is suitable for low and medium vacuum fields, mainly used for pumping out air and other dry gases. It is one of the main equipments for low and medium vacuum. It can be used alone or as a backing pump for other vacuum pumps. The vacuum pump has the characteristics of reliable operation, few wearing parts, low vibration, low noise and high efficiency. Germany Puxu R5/RA series vacuum pump is an imported technology, and the wearing parts are imported components or imported materials. X-type series vacuum pumps can completely replace similar foreign products. The vacuum pump has the characteristics of reliable operation, few wearing parts, low vibration, low noise and high efficiency.

The working principle of Puxu vacuum pump RA0160:

The freely slidable vanes are embedded in the groove of the pump rotor, and the pump rotor is eccentrically placed in the pump cavity. When the rotor rotates, centrifugal force causes the vanes to act on the wall, creating many air chambers in the air cushion compression space between the rotor and the pump cavity. When these air chambers pass through the air inlet, air flows in, and as the rotor continues to rotate, the air is compressed due to the eccentricity of the rotor until it is released when the compressed air passes through the outlet.

Puxu RA0100F-RA0160 vacuum pump Puxu rotary vane vacuum pump working principle Rotary vane vacuum pump (referred to as rotary vane pump) is an oil-sealed mechanical vacuum pump. Its working pressure range is 101325~1.33×10-2(Pa), which belongs to low vacuum pump. It can be used alone or as a backing pump for other high vacuum pumps or ultra-high vacuum pumps. It has been widely used in the production and scientific research departments of metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum and medicine. The rotary vane pump can pump out the dry gas in the sealed container, and if it is equipped with a gas ballast device, it can also pump out a certain amount of condensable gas. But it is not suitable for pumping out the gas with high oxygen content, corrosive to metal, chemical reaction to pump oil and particulate dust.

All R5/RA series vacuum pumps of Puxu vacuum pump have the following common characteristics:

1. Precise design. Solid structure. Light weight. Easy to install and maintain.

2. Air cooling (air cooling).

3. Value knot drive, can avoid the slack or loss of rotating belt and gear.

4. The oil mist filter with oil content does not need to discharge the gas outdoors.

5. There is a check valve at the air inlet. When the pump stops, the check valve can isolate the pump from the system and avoid the backflow of vacuum oil.

6. Low vibration, no need to fix the pump with foundation bolts.

7. The running sound is small.

8. With gas ballast valve, it can be applied to steam process.

9. That is, the water vapor entering the pump inlet between the vacuum degree of 0.1mbar and 40mbar,

It will be completely discharged from the pump outlet without condensation in the pump.
