Moving and Jam:

The shaft fan may be damaged or jammed during transportation. This may disrupt the balance of the propeller and reduce its performance.

Wear and Tear

The propeller may wear out or wear out over time. In this case, the balance of the propeller may be disrupted and its efficiency may decrease.

Breakage and Cracking:

Propellers operating at high speeds may break or crack over time, which may be due to material quality or inadequate maintenance and use.

Deformation :

Deformations may occur in propellers operating under high temperature or pressure. This may negatively affect the performance of the propellers.

Balance Problems:

Unbalance of propellers can usually be caused by errors during construction or may occur over time. Imbalance may cause vibration or noise.
