Bearings exhibit excessive temperature rise:

Bearings bracket seat severe vibration

② Poor quality lubricating oil, deterioration, presence of dust, sand, dirt, and other impurities; excessive or insufficient tension on the bearing housing connecting bolts; bearing operation with insufficient oil.

Axle and bearing misalignment, with the front and rear axles' bearings not concentric.

④ Bearing damage or the end of bearing life has been reached.

⑤ Turbine shaft and motor shaft unbalanced; belt groove misalignment.

2. Turbine Vibration

Impeller unbalance

②Loose impeller screws or deformed wheel disc and blades;

③ Insufficient or unstable fundamental rigidity;

④ The case and bracket bearing connection bolts are loose.

⑤ Misaligned shock absorber causing center of gravity shift

3. Impeller Shining Up:

Impeller imbalance or deformation

② Housing or intake opening friction with impeller

③ Impeller reversal causes loosening of impeller fasteners.

④ Impeller shaft flange hole and shaft loosening

⑤ Poor installation of air intake and exhaust ducts for the wind turbine.
