Proactive Maintenance Strategies Minimize Production Disruption

  • Initial Vibration Rise: The Total Vibration Energy (TVE) rose from 0.66 ips to 0.8 ips.
  • Significant Vibration Increase: The TVE spiked to 1.1 ips and then to 1.18 ips.
  • Return to Normal Levels: Within an hour, on the same day, the TVE (total vibration energy) measured on Motor DE had dropped to 0.1 ips (which is typical for a good motor, running  uncoupled, on no-load).

Supporting Data

The long-term trend below showed no gradual increase, i.e. the trend indicates slow and persistent development of a machinery fault, and was persistent for several months.

Solution:

Shoreline’s team conducted a thorough post-event analysis utilizing vibration data and trend charts. Key findings included:

  • No Gradual Degradation: Long-term vibration trends did not show a slow and persistent increase, suggesting a rapid failure mechanism.
  • Axial Vibration: Predominant vibration signals were in the axial direction, pointing towards misalignment or looseness in the belts, sheaves, or foundation bolts.
  • Non-harmonic Peaks: Frequency analysis revealed non-harmonic peaks indicative of belt/pulley issues and potential structural resonance.

Evidence of Success:

Based on the analysis, Shoreline provided actionable recommendations:

  • Realignment: Realign belts and sheaves to ensure proper operation.
  • Looseness Check: Inspect and tighten belts, sheaves, and foundation bolts to eliminate excessive vibration.
  • Structural Assessment: Evaluate the motor/fan mounting structure for looseness and potential resonance issues.

Results:

  • Root Cause Identification: Successfully identified the root cause of the belt failure as misalignment/looseness.
  • Reduced Downtime: Facilitated quicker repairs and minimized production disruption.
  • Improved Predictive Capabilities: Enhanced anomaly detection algorithms to prevent future occurrences and improve overall asset reliability.

Shoreline's actions to Improvement Future Anomaly Detection:

  • Faster Trend Analysis: Reduced averaging time for vibration values to detect rapid changes more effectively.
  • New Anomaly Detector: Introduced an algorithm specifically designed to identify failures like the belt failure, where the motor continues running unloaded after the event.

Conclusion:
