    Rotary Vane Vacuum Pump Details Introduction

    Tips: Troubleshooting Smoke and Oil Injection of Rotary Vane Vacuum Pump

    It refers to smoke or oil injection of rotary vane vacuum pump at the air outlet during operation.

    1. Smoke: if the pump has just started to operate, the smoke phenomenon is normal. If the smoke lasts for a long time, it is abnormal.
    Solution: Check the air inlet of the vacuum pump, including pipe, valve, and container whether there needs repairing.

    2. Oil injection indicates that there are a large number of leakage points outside the air inlet, or even the air inlet is exposed to the atmosphere.
    Solution: Seal the air inlet of the pump to let it run, and if there is no spray oil, there is a leak point; check whether the exhaust valve disc is damaged, and if so, replace the broken exhaust valve disc.
