What impact will the distorted fan blades on the turbine rotor have on the generator?

Introduction What impact will the fan blades on the hydroturbine rotor have on the generator? Deformation of the fan blades on the hydroturbine rotor will have the following effects on the generator? 1. The engine cooling fan blade is broken.

What impact will the distorted fan blades on the turbine rotor have on the generator?

Deformation of the fan blades on the hydrogenerator rotor will have the following effects on the generator.

1. The motor cooling fan blade is broken and the motor cannot dissipate heat effectively. As the temperature increases, the motor becomes hot and accelerates the aging of the stator insulation.

2. If the fan blades are partially damaged, it will cause unbalanced operation, the motor will vibrate, and the stability of the machine base will be damaged.

Cracked and struck by lightning. According to the official website of China Profile Network, it is displayed.

1. Crack. The fan blades are exposed to the outside and the working environment is harsh. After a long time of operation, some cracks will occur on the surface, which will affect the stress on the turbine and cause unevenness. stress on the transmission chain andcause The gearbox gear is defective, which causes the fan blades to be stuck, and the fan blades need to be replaced with new ones in time.

2. When struck by lightning, the blades are made of fiberglass. There is moisture between the layers of fibers during operation. When struck by lightning, a large current instantly passes through the lightning protection channel. the generated heat causes the moisture to instantly evaporate into water vapor which will damage the inner fiber layer of the fan blades, causing the fan blades to be blocked, and the fan blades need to be replaced with new ones in time .
