1. The Large Shaft End: The large shaft end is the most prone to cracking and fatigue damage on the generator rotor large shaft, so it should be inspected intensively.
2. The middle part of the big shaft: Cracks and fatigue damage can also occur in the middle part of the big shaft, and regular detection of defects is necessary.
3. Big Shaft Bearing Position: The big shaft bearing position is one of the most important parts of the big shaft of the generator rotor. If cracks or fatigue damage occur, generator operation may be unstable. and even cause an ACCIDENT.
4. The connection between the big shaft and the stator: Cracks and fatigue damage can also occur in the connection between the big shaft and the stator, and regular fault detection is required.essay.
