Rotary vane vacuum pump is widely used, is a kind of vacuum equipment, most of our manufacturers used to match the vacuum drying box. Recently, a customer in jiangsu province, in a vacuum drying and and rotary vane vacuum pump when doing the experiment, the rotary vane vacuum pump the oil spill, say starting power button, the exhaust valve on rotary vane vacuum pump did not open, the consequence is the temperature inside the pump, oil pump suction, unplug after the pipe connection, once again open the power of the rotary vane vacuum pump, oil pump and flow from inlet nozzle, lie between a day later, the inside temperature is down, but open pump, oil pump or out, customers don't know what to do, so consulting us.
Through technical analysis, research and experiment, four conclusions are drawn, specifically as follows:
1. The motor is connected backwards, that is, the pump is reversed, to see whether the direction of rotation and the above marks are the same;
2. There is no fault in the vane pump itself, disconnect the outlet and inlet pipelines of the pump, and then start the pump again for 10 minutes to see if it is normal;
3. Check the sealing ring, the sealing ring is worn or assembled incorrectly; The sealing ring is worn, replace the sealing ring, if the assembly is wrong, reassemble;
4. Check whether the front and rear end faces of rotary vane vacuum pump are smoothed, and whether the end plates are tightened; If it is not tight, repair the end face flat, tighten the end plate.
Above is the analysis and arrangement of oil leakage fault of rotary vane vacuum pump, hoping to help the general rotary vane vacuum pump. What about rotary vane vacuum pumps? Can be used alone, can also be used as booster pump, diffusion pump, molecular pump and titanium pump, and can also be used for electronic device manufacturing, vacuum drying, filtering, welding, metal smelting.
