Inspection Method for Cylinder of Liquid Ring Vacuum Pump

The liquid ring vacuum pump is a kind of coarse vacuum pump. The maximum vacuum it can obtain is 2000-4000Pa. The vacuum degree of the unit composed of the liquid ring vacuum pump and the vacuum pump can reach 1-600 Pa. The liquid-ring pump can also be used as a compressor, called the liquid-ring compressor. It belongs to the low-pressure compressor, and its pressure range is 1-2*105Pa gauge pressure. Any machine will have some minor faults after a long time of use, so it is necessary to master some solutions.

Inspection method for cylinder of liquid ring vacuum pump:

1. Measure the roundness and cylindricity of the cylinder of the water ring vacuum pump, and determine the boring cylinder or replacement according to its wear degree.

2. Cylindricity and cylindricity of cylinder should comply with relevant regulations.

3. There should be no cracks, sand holes, scars, grooves and other defects on the inner surface of the cylinder. The surface roughness is 1.6.

4. Cracks or leakage are not allowed in cylinder water jacket.

5. The cylinder diameter of the hammer water ring vacuum pump should not increase more than 2% of the original size, and the cylinder wall should not be thinner than 1/12 of the original thickness.

Correct maintenance of the cylinder of the liquid ring vacuum pump will be more conducive to the use of the pump, but also to extend its life. At the same time, when inspecting the cylinder of dry vacuum pump, we should pay attention to all aspects, such as surface, diameter, etc., which need to be inspected.
