Vacuum pump in assembling several problems
1. Vacuum pump shaft is rotor shaft equipment to determine whether it is bending, deformation.
2. Whether the rotor balance condition meets the standard.
3. The cooperation space between vacuum pump blade and rotor.
4. Several times the amount of sealing buffer compensation arrangement is not required to reach the required amount.
5. Whether the concentricity between the pump rotor and the bearing position is required.
6. Space adjustment between bearing and end cover.
7. Adjust the open space of sealing part.
8. Is the coaxiality of the coupling in line with the needs? The vacuum pump oil is affected by temperature, air, metal catalysis, mechanical shear, harmful medium, etc. in the application, the base oil in its composition will react with oxidation, cracking and polymerization, and its function will gradually deteriorate.
Vacuum pump oil in operation of change
The additives in the vacuum pump are also gradually consumed and invalid in use, resulting in the decline of function and the occurrence of harmful components to the equipment, which are called aging or degradation. When the damage to the equipment is greater than its good effect after aging and degradation to a certain extent, it is necessary to change the oil.
Generally speaking, the degradation of vacuum pump oil is mainly the reaction process of hydrocarbon oxidation, which will be followed by aldehyde, ketone, alcohol to organic oxy acid. The reaction is accompanied by different degrees of differentiation and polymerization. The central product is hydrocarbon peroxide. Its highly active unstable compounds are easy to attack metal and form special wear and defects. High level vacuum pump oil is rich in high-level vacuum pump oil It can delay the degradation rate of vacuum pump oil or reduce the damage of degradation products to vacuum pump.
In summary, the connotation of vacuum pump oil will change when it rotates at high temperature and high speed for a long time. For example, after being used for a certain period of time, the vacuum pump oil will be released like the water in the foul water ditch. 80% of the oil is formed by emulsification. If the viscous substance occurs, it will be clarified that it is carbonized.
