Online Turbine Blade Vibration & Tip Clearance Monitoring System
Application: The free standing and especially shrouded or bandaged blades are often used in turbomachines of large capacity, mainly in steam turbines.
To avoid accidents with extensive economic losses, there appears an urgent need to equip at least the last stage of low pressure turbine (with respect to the dimensions of the installed blades) with monitoring to provide information of blades vibration, their damage and residual lifetime.
Typical faults detections
- Blade vibration measured from Time of Arrival signals
- Blade untwisting and angle between leading and trailing edge
- Blade lean
- Shaft speed
- Air gaps between rotating and stationary parts (indirect measurement has to be calibrated)
- Temperature measurement
- Torsional shaft vibration
