An optimum device for blade crack diagnosis/prognosis researchSpectraQuest’s turbine blade crack research test rig has been specifically designed to simulate turbine blade crack and other machinery faults for research and educational purposes. With this test rig, the blade crack diagnosis/prognosis can be studied thoroughly through the wireless strain gauges attached on the blades.
- Turbine blade dynamics
- Blade crack propagation
- Blade crack diagnosis/prognosis
- Other mechanical fault studies, which include, but not limited to
- Bearing faults
- Bent shaft
- Mechanical rub
- Induction motor faults, which include, but not limited to
- Broken rotor bar
- Shorted stator turn
- Eccentric gap
- Bowed rotor
- Variable pitch fan module with strain gauges attached to the blades.
- Telemetry system.
- Weights to change the mass moment of inertia are installed on the rotors.
- An adjustable blade rub excitation device is attached to the baseplate at the circumference of the blades.
- The generator is used as a braking mechanism. The output from the generator is fed to a variable resistor (rheostat) where the load can be easily adjusted.
- Rotor dynamics and most of the mechanical (except belt and gearbox) or motor faults can be studied.
- Features modular, re-locatable component configurations, convenient instrument mounting, drive train alignment, and robust design.
