Case studies
Typical damage that can be detected with the vibration analysis system COMOS and evaluated in terms of depth of damage include:
- blades: Static and dynamic unbalance , icing , misalignment of the rotor blades
- bearing: Wear of main bearings (slow moving parts ) , the gearbox mounting (slow and fast moving parts) and generator bearings (fast moving parts )
- Drive: Irregularity in the brake system, clutch, drive, oil pump
-
Gear: Wear of the teeth , incipient cracking and propagation
