From initial inquiry to completed report
You submit a service request. We review machine specs, operating conditions, and access constraints. A brief site survey confirms equipment type, shaft configuration, and vibration baseline.
Piezoelectric accelerometers are mounted at bearing housings and key structural points. We capture baseline vibration spectra under steady load and record temperature, speed, and alignment readings.
Spectrum and time-waveform analysis identify fault frequencies: unbalance, misalignment, bearing wear, or rotor bar issues. Severity is rated against ISO 10816-3 thresholds.
For balancing or alignment, we perform on-site corrections using portable balancers and dual-laser systems. Thermal growth compensation is applied for hot-running equipment.
Post-correction measurements confirm vibration levels within acceptable limits. A detailed report includes before/after spectra, correction actions, and recommended follow-up intervals.
Client feedback
“Royiversen diagnosed a bearing defect in our 200 kW cooling fan three weeks before failure. The vibration report gave us clear lead time to order parts and schedule the repair during a planned outage. No unplanned downtime.”
Predictive analysis“After the laser alignment on our fan-motor train, the vibration dropped from 7.2 mm/s to 1.1 mm/s. The thermal growth compensation made the difference — the machine stays aligned even at full load.”
Laser alignment“Dynamic balancing on our 350 kW fan reduced the unbalance force enough to stop the recurring coupling failures. The before-and-after data gave us confidence to extend the inspection interval.”
Rotor balancing“The monthly vibration reports for our 1.2 MW induction motors let us catch a rotor bar crack early. We replaced the rotor during a scheduled shutdown instead of losing a weekend of cooling capacity.”
Motor diagnostics“We had a persistent 2x line frequency vibration on a 500 kW motor. Royiversen identified a soft foot condition and a slight eccentricity. After shimming, the motor runs smoothly — no more false trips.”
Vibration analysisChoose the diagnostic and alignment package that matches your equipment profile and maintenance schedule.
Portable dynamic balancing for single- or two-plane correction on cooling fans and blowers up to 500 kW. Includes pre-run vibration baseline, trial weight calculation, and final ISO G2.5 report.
