Wan Kun Fan Science Popularization - Dynamic Balancing Test of Fans

How much do you know about the dynamic balancing test of fans?

Dynamic balancing actually means adjusting the mass center of the impeller to be as close to the impeller shaft as possible by adding or subtracting weight in certain areas. This is done by installing balancing weights such as bolts, nuts, and washers on the front or rear discs of the blades to correct the dynamic imbalance of the impeller. By doing so, the vibration and noise during the operation of the fan can be significantly reduced. Why is dynamic balancing of the impeller so important, and why should it be carefully adjusted for you? Because excessive imbalance can lead to excessive vibration, which can cause noise and damage to the fan.
