During the application of the vacuum pump unit, the process water, calcium magnesium hardness, pH value, conductivity, total alkalinity, temperature and other factors will have a certain impact on the accessories of the vacuum pump unit, resulting in the increase of unplanned shutdown times, production interruption and the production efficiency of the unit. Therefore, in the process of use and maintenance, we should pay attention to the timely replacement of some vulnerable parts.
1. The bearing bush of sliding bearing is made of copper tin alloy with poor wear resistance. It is one of the vulnerable parts of vacuum pump unit that are easy to wear and burn out. Bearing shells can generally be repaired or replaced with new parts. Generally, the average service life of rolling bearing is 5000 hours, but it is easy to wear or damage due to improper installation, long service time or poor maintenance. Except that individual parts of rolling bearings can be replaced with new ones, the integral parts shall generally be replaced.
2. Impeller is an important working part of vacuum pump unit, which is made of cast iron. Due to manufacturing quality, use and other reasons, the impeller may be damaged, such as cracks, dimples or holes formed on the surface due to cavitation, thinning or eccentric wear of the blade due to long-term punching and grinding, and even broken by sundries. Some defects can be repaired, and some defects cannot be repaired, that is, the impeller should be replaced with a new one.
