How to deal with the leakage of vacuum pump

Vacuum pump is a device that changes, generates and maintains vacuum in a closed space by various methods. When we use it, air leakage will occur. This phenomenon will bring a lot of trouble to the equipment. Here, we will introduce the reasons for air leakage of the equipment.

1. The front and rear lateral caps are not concentric:

Maybe the front and rear side covers have different axes, and the result is the same as the bearing deflection.

2. Fever:

As the temperature rises, the saturated vapor pressure rises, which reduces the vacuum, but it has no effect on the exhaust pressure.

3. Insufficient sealing:

Tighten all connection bolts, tighten packing cap, tightly wrap pipelines and instruments with other parts or replace gaskets and packing.

(2) For air leakage, oil lime can also be applied as temporary remedial measures.

4. Bearing skew:

This phenomenon causes the impeller to be inclined in the pump body. For single-acting pumps, the axial clearance is not uniform. When the blade turns brilliantly, it will inevitably friction with the side cover, scratch the side cover and the impeller end face, so as to increase the axial clearance.

(2) When the compressed chamber gas passes through the enlarged clearance, it leaks into the suction chamber in large quantities, which reduces the vacuum or exhaust pressure. At this time, it is necessary to remove the bearing and repair it, and then install it correctly.

Vacuum pump refers to the device or equipment which can get vacuum by mechanical, physical, chemical or physical chemical methods. Therefore, air leakage of the equipment is a very serious problem. When we use it, we should remember to maintain and maintain it, which will reduce the leakage of the equipment.
