In order to ensure the normal operation of the vacuum pump unit, its composition and structure play an important role in it. At the same time, it is closely related to the reasonable design of its structure. The cylinder of the vacuum pump unit is of great significance. In order to maintain the smooth operation of the equipment, it needs to meet certain requirements of the use of the air cylinder.
1. The roundness and cylindricity of the cylinder meet the relevant regulations.
2. Measure the roundness and cylindricity of the cylinder of the vacuum pump unit, and determine the boring or replacement of the cylinder according to its wear degree.
3. The increase of cylinder diameter of vacuum pump unit shall not exceed 2% of the original size, and the thinning of cylinder wall shall not exceed 1 / 12 of the original wall thickness.
4. No crack or leakage is allowed in the cylinder water jacket.
5. 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.
To sum up, in order to ensure that the vacuum pump unit does not break down during operation, it is necessary to meet the above use requirements of the cylinder. In order not to affect the normal work, daily maintenance of the cylinder and other components is conducive to the improvement of work efficiency and the extension of its life.
