What are the common mistakes of high temperature fans?
Release time:2016-01-26
Although the high-temperature fan has unique performance, it is used instead. The set gap outside the high-temperature fan bearing is aligned, a running ring situation occurs, and the fan vibrates through. There are often misunderstandings when dealing with these two issues. Today, let the editor of Zibo Yingfeng Fan show you where high-temperature fans are prone to machine errors!
1. The fan has a large vibration
Many people think that the large vibration of the fan is caused by the imbalance of the rotor. In fact, this is one of the reasons. There are many shortcomings in terms of a large number of integrations, the basic characteristics and balance being the most basic. However, if you don't consider it, you can increase the vibration value by just passing the scene, and you cannot deal with the basic results. Sometimes it leads to repetition of the vicious circle. Volume, its spacing characteristics are very similar to balances, but not balanced. Dynamic mismatches such as loose rotor and impeller disc connections cannot eliminate vibration.
2. High-temperature fan operation cycle
During fan maintenance, the outer ring of the bearing and the bearing plate have an absolute sliding collision trajectory, an obvious corridor appears on the upper cover of the bearing plate, and a slight sintering phenomenon appears on the outer ring of the bearing. If a misunderstanding occurs in the high-temperature fan, this situation occurs, and the "bearing race" will never compress the bearing and cause an accident. During operation, the non-locating end bearing is driven axially by the shrinkage of the main shaft. The outer ring of the bearing is driven by a steel ball, and the inner ring of the bearing seat floats on a certain horizontal surface instead of sliding. Since the main shaft of the fan is operated by heat shrinking, one end of the bearing device flows and one end blows air, and there is a gap between the bearing outer ring and the bearing housing hole.
Due to these two shortcomings and cause analysis, they are often found in the small version of the error. After the high temperature fan is found to be faulty, unless there is a sufficient reason for repair, the high temperature fan must be carefully inspected and maintained. This may cause other problems and is really worth it. If you want to learn more, please feel free to follow us.
