KMbalancer II dynamic balance instrument to tell you the cause of rotor mass imbalance

In the field of fan bearing vibration, rotor mass imbalance vibration accounted for the majority.

The main causes of rotor mass imbalance are as follows:

1. Impeller wear (mainly blade) is not uniform or corrosion.

2. Uneven ash or attachment (such as rust) on the leaf surface.

3. The hollow blade of the wing or the cavity of other parts is sticky ash.

4. The local high temperature of the spindle makes the shaft bend.

5. The impeller is not balanced after maintenance.

6 impeller strength is insufficient to cause impeller cracking or local deformation.

7. The parts on the impeller are loose or the connecting parts are not fastened.
