The water ring vacuum pump is a kind of crude vacuum pump. The limit vacuum it can obtain is 2000 ~ 4000Pa. The vacuum degree of the unit composed of the vacuum pump and the vacuum pump can reach 1 ~ 600Pa. Water ring pump can also be used as compressor, called water ring compressor, is a low-pressure compressor, its pressure range is 1 ~ 2 × 105Pa gauge pressure. Any machine in the use of a long time after there will be some small failures, so it is necessary to master some solutions. After using water ring vacuum pump for a period of time, it is necessary to carry out certain maintenance, among which, the maintenance of the cylinder is particularly important, so let's take a look at how to overhaul.




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




2. The roundness and cylindricity of the cylinder meet the relevant regulations;




3. The inner surface of the cylinder shall be free of cracks, sand holes, scars, grooves and other defects, and the surface roughness shall be 1.6;




4. The water jacket of the cylinder is not allowed to have cracks or leakage;




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




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