The centrifugal fan has a problem of poor dynamic balance, is it caused by the impeller? Today we will talk about this problem. In fact, there are many factors that cause poor dynamic balance of centrifugal fans, which cannot be considered unilaterally. The specific contents are as follows:
1、 The fan impeller is unbalanced; During the long-term operation of the fan, a large amount of dust or foreign matter accumulates on the surface of the impeller, the impeller is worn or corroded during the operation, the impeller is loose, and the impeller is not balanced after repair;
2、 Caused by fan bearing failure; The bearing is worn or broken, the fixing bolts of the bearing box are loose, and the bearing is not installed properly (for example, the coupling is not aligned);
3、 Vibration generated by air duct system or other equipment causes poor dynamic balance of centrifugal fan;
There are many factors that cause poor dynamic balance of centrifugal fan, so we can't judge according to one-sided state only. We need to use a vibration balancer to check one by one, find the root of the problem, and then deal with it.
