Product Features

Causes of vibration caused by unbalance of fan rotor: 1. Fan blades of fan are corroded or worn seriously; 2. The fan blade does not run after assembly, and the shaft is bent due to the weight of the impeller and the main shaft itself; 3. impeller surface uneven attachments, such as rust, dust or asphalt, etc.; 4. transportation, installation or other reasons, resulting in impeller deformation, causing impeller out of balance; 5. Balance weight on impeller falls off or fails to find balance after overhaul.
Treatment: 1. Repair or replacement; 2. Re - examine and repair. If it is not used for a long time after final assembly, it should be turned regularly to prevent the shaft from bending. 3. Remove attachments; 4. Repair the impeller and do static and dynamic balance test again; 5. find a balance
Reasons for overheating of fan bearings: 1. friction between fan main shaft or parts on main shaft and bearing housing; 2. The motor shaft is not concentric with the fan shaft so that the inner rolling bearing in the bearing box does not move; 3. Too much grease in the bearing box; 4. There is a gap between the bearing and the hole of the bearing box and it is loose, and the bolt of the bearing box is too tight or too loose.
Treatment method: 1. Check which part is rubbing and then deal with it; 2. Adjust the concentricity of the two shafts; 3. The grease in the box is 1 / 3 ~ 1 / 2 of the box space; 4. Adjust the bolts.
Reasons for air volume reduction: 1. Speed reduction; 2. pipeline blockage; 3. Seal leakage.
Processing method: 1. Check the power supply voltage; 2. Dredge and clean the pipeline; 3. Repair or replace the seal.
