Rotary vane vacuum pump troubleshooting method

Rotary vane vacuum pump is suitable for the extraction of dry or containing a small amount of condensable vapor gas, not suitable for the extraction of excessive oxygen, explosive, corrosive, the vacuum pump oil plays a chemical role and contains a large number of solid particles gas. In the operation of rotary vane pump, if the operation is not correct, it will lead to some faults, serious will also lead to its stop operation. Next, let me introduce to you some of its common faults and troubleshooting methods:

1, this rotary chip vacuum pump oil grades are different from the original ones. Different brands of pump oil, due to different saturated vapor pressure, the result will be different.

Exclusive method: select the correct vacuum pump oil according to the product type.

2. The gap between components in rotary vane vacuum pump is larger. This is a long drawn out air containing dust in the body, causing the clearance between the rotary vane and the stator to increase.

Troubleshooting: check whether the gap is too large and replace the new parts.

3, the oil circuit in the pump is blocked or not smooth, and the pump chamber does not maintain a certain amount of oil.

Troubleshooting: check whether the oil circuit is open and add the same type of vacuum pump oil.

4, the temperature of the gas being pumped may be too high.

Troubleshooting: reduce the temperature of the gas being pumped, or add a corresponding heat exchanger on the rotary vane vacuum pump.

5, the water vapor and impurities in the gas are too high to cause the rotary vacuum pump to emulsify or discolor.

Elimination method: Pump out the vacuum pump oil, replace the same type of pump oil, and set up a filter to ensure that the steam and impurities in the pumped gas do not enter the pump.
