    Rotary Vane Vacuum Pump Details Introduction

    Tips: Troubleshooting Vacuum Reduction of Rotary Vane Vacuum Pump

    Here refers to the current measured vacuum of the rotary vane vacuum pump is lower than the factory index or the previous use of the vacuum. There are many causes of low vacuum.
    1. The grade of rotary vane vacuum pump oil added this time is different from the original one. Different vacuum pump oil grades can affect the vacuum produced by the vacuum pump due to different grades of oil have different saturation vapor pressure.
    Solution: use the correct vacuum pump oil according to the product model and specification.
    2. Another case of low vacuum caused by vacuum pump oil is emulsified discoloration of vacuum pump oil, or too dirty.
    Solution: drain out all vacuum pump oil in the pump, replace the same type of vacuum pump oil, and prevent the vapor and impurities in the pumped from entering the pump.
    3. The temperature of the pumped gas may be too high.
    Solution: reduce the temperature of the pumped gas, or can add a corresponding heat exchanger.
    4. The oil channel in the pump is blocked or not free, and a certain amount of oil is not maintained in the pump chamber.
    Solution: check if the oil line is clear, and add the same type of vacuum pump oil.
    5. The gap between the vane and the stator is large. This is because the dust contained in the pumped gas for a long time causes the wear of the vane and the stator to increase the gap between them.
    Solution: check if the gap is too large and replace the parts.
