Discover how Vibrovision Engineering has transformed industrial operations through expert machinery services, condition monitoring, and innovative solutions.
Hydro generator vibration analysis
The gaps were corrected, and in-situ dynamic balancing was subsequently performed. After rectification, the vibration levels were successfully reduced to 45 microns at the UGB and 38 microns at the LGB, restoring smooth and stable machine operation.
Hydro generator high shaft vibrations
The machine was successfully restored to smooth operation, ensuring reliable and safe performance.
Spectrum analysis revealed a combination of soft foot and rotor imbalance as the root causes.
Vibrovision team analyzed and corrected Soft foot was corrected, followed by in-situ dynamic balancing, which reduced vibration levels to 1.2 mm/s (NDE) and 0.7 mm/s (DE).
