How to repair the centrifugal fan
Author:
1. Wind wheel
After the long-term operation of the centrifugal fan, the wind wheel will have different degrees of wear and some foreign matter due to corrosion from different gases. Some maintenance personnel found that the wind wheel was corroded and punctured, and the perforation was repaired with a book iron. However, after such maintenance, but when installing the fan, you will find that it cannot maintain balance. Some maintenance personnel concluded that the fan was not installed after the machine was disassembled or the fan could not be reinstalled. The reason is that the maintenance staff is working on the problem and the wind wheel is unbalanced. Each wind wheel is balanced when leaving the factory, because even if corrosion occurs, the wind wheel will move at high speed. The degree of corrosion of the entire rotor is the same or different. If the wind wheel is found to be unbalanced or corroded, you can see if the user is changing the wind wheel.
2. Transmission belt
The centrifugal fan is driven by a transmission belt. The drive belt is also a component that is prone to wear. Centrifugal fans will have two or more belts. After discovering the use of the drive belt, many companies directly replaced the problematic drive belt. But soon, you will find that the other belt is damaged, and the new belt wears faster than normal. This goes into a loop where the belt is constantly changing. Just change the two belts, you can solve this phenomenon. The main reason is that the two belts are used in different ways, and a belt is changed. The new strap is stretched differently from the old strap, stretching the new strap to the same length as the old strap. The wear rate of the new belt will increase, which will lead to continuous belt replacement.
