What causes severe centrifugal fan vibration? Today, we'll discuss possible causes:
1. The fan shaft and electrode shaft are not concentric.
2. The foundation or integral support is insufficiently rigid.
3. Loose impeller bolts or rivets, or deformation of the impeller.
4. Loose fit between the impeller shaft and the shaft.
5. Loose bolts connecting the casing, bearing seat and support, and bearing seat and bearing cover.
6. Dust and dirt buildup on the blades, blade wear, impeller deformation, and shaft bending can cause rotor imbalance.
7. Improper installation of the fan inlet and outlet ducts, resulting in resonance.
The above are potential issues that may cause fan vibration. If you have any questions about fan after-sales service, please contact us!
