Cause of vibration caused by unbalance of rotor of centrifugal fan
1. The centrifugal fan blade corrosion or wear serious;
2. After the wind turbine blade assembly is not running, due to the weight of the impeller and the main shaft itself, so that the shaft bending
3. The impeller of uneven surface attachment, such as rust, dust or asphalt;
4. Transport, installation or other reasons, resulting in deformation of the impeller, causing the impeller to lose balance;
5. The balance of the impeller on the block off or after the maintenance is not looking for balance;
Treatment method:
1. Repair or replacement;
2. Re assembly after the overhaul, as long as not regularly to prevent turning shaft bending;
3. Removal of attachments;
4. Repair the impeller, to do the static and dynamic balance test;
5. To find a balance;
