Shaft System Reliability:
Micrometer Precision
The Mission: A Large Vertical Francis unit experienced repeated tripping due to excessive vibration. Our objective: Pinpoint the latent misalignment and restore dynamic stability.

01 The Threat Vector
Root cause analysis pointed to chronic misalignment introduced during the last major overhaul, exceeding the acceptable 0.1 mm/m tolerance. This latent flaw created the 48% dynamic instability factor, which accelerates structural fatigue across the entire shaft line, guaranteeing premature bearing and seal failure.
> RISK DETECTED: SHAFT RUNOUT > 0.15 MM
> CONSEQUENCE: BEARING FAILURE IMMINENT
02 Tactical Execution
We deployed the AnoHUB Precision Protocol to restore the zero-point:
-
Forensic 3D Scanning Used high-precision laser scanning to map the exact geometry of the shaft line in 3D space, pinpointing the exact source and angle of misalignment.
-
Micrometer Re-Alignment Executed a systematic re-alignment of the thrust and guide bearings to achieve the 0.05 mm/m non-negotiable tolerance across the generator and turbine assembly.
-
Post-Assembly Validation Dynamic vibration testing confirmed the elimination of abnormal harmonics and guaranteed stability across all load points, validating the repair.
