Explosion-proof centrifugal fan manufacturers: to discuss the reasons of excessive movement caused by the fan

Axial flow centrifugal fan, the main use is very common, is the cyclone with the axial direction of the fan blade, such as electric fan, air conditioning outdoor unit cooling fan is the axial flow method of operation fan. It is often called "axial fan" because of the flow of the parallel surface of the steam body in the fan shaft. Axial flow fans are generally used in places where the total flow rate is higher and the working pressure is lower. The axial fan fixes the stationary part and makes the gas move. The key of the axial flow fan is composed of the fan impeller and the casing. The structure is simple, but the data information is very high. Among them, the common faults with strong vibration of the fan and their causes are analyzed as follows:

1, the casing or air inlet and impeller friction

2. The fan shaft is not parallel to the motor shaft, and the belt disc is shifted

3. Loose impeller bolt or impeller deformation

4. Basic bolt loosening or impeller deformation

5, leaves have dust, stains, erosion or shaft bending so that the motor rotor imbalance

6. The disc hole of the leaf wheel shaft is loosened with the shaft

7. The anchor bolts connecting the housing and the support frame, the belt seat bearing and the support frame, the belt seat bearing and the rolling bearing cover are loose

8. The construction of the inlet and outlet pipes of the fan is not good enough, resulting in co-vibration.
