Influence vacuum pump vacuum degree of seven factors

1, the vacuum pump blade wear, and the cylinder body conflict between the contact surface can not be large, resulting in a lack of vacuum.
2, cylinder body wear, cylinder wall may appear wear, resulting in a lack of vacuum.
3. Rotor displacement. The standard installation position of rotor and end cover is offset, resulting in insufficient vacuum.
4, vacuum pump leakage, vacuum pump at the beginning and end of a long time after the use of the seal gasket aging caused vacuum pump leakage, resulting in insufficient vacuum.

5. Whether the motor is normal. Motor speed is not normal pumping speed will slow down, resulting in a lack of vacuum.
6, vacuum pump oil emulsification, carbonization. Vacuum pump in the long-term use of the process is not usually replaced and artificial conditioning, vacuum pump oil will produce emulsification or carbonization phenomenon, resulting in the vacuum pump cylinder wear, tubing congestion, oil filter congestion and a series of problems.
7, vacuum pump oil filter congestion or damage. Vacuum pump oil filter is also called oil mist separator, oil filter, exhaust filter, etc., if the oil mist separator produces congestion, the gas pumped into the pump body will not be easily removed, at this time the pump internal pressure is too high, pumping speed is reduced, the vacuum degree drops.
