Fans often produce noise during operation, which brings us troubles. Usually, the noise of the fan is mainly due to the damage of the impeller Dongtai balance. As long as we adjust it, the problem can be solved, but the axial flow exhaust fan is due to its structure. The reasons for the noise are also different.
Abnormal noise during the operation of the axial flow fan needs to be stopped and checked immediately. The main reasons are summarized as follows:
1. The selected fan lubricating oil does not match, so the resulting friction occurs;
2. The interior of the fan enters the sundries, which will generate noise during the operation of the fan;
3. Noise caused by bearing wear and tear;
4. The noise generated by the friction between the rotor and the casing;
5. The coupling key is loose;
The structure of the axial flow fan is equipped with noise reduction settings, so there is usually no noise during operation. Once there is a large noise, it needs to be stopped and checked immediately. The above are several reasons why the axial flow exhaust fan produces noise. I hope it will be helpful to everyone. More knowledge will continue to be summarized for you.
