Predictive diagnostics to prevent failures and extend pump life.
Vibration analysis is a non-intrusive, predictive maintenance technique that detects developing mechanical faults in centrifugal pumps long before they cause catastrophic failure. EKG Malaysia’s certified analysts use advanced equipment to monitor, diagnose, and prescribe corrective actions, ensuring maximum uptime and reliability for your critical pumping assets.
What Vibration Analysis Detects:
Imbalance: Uneven mass distribution on the impeller or coupling.
Misalignment: Angular or parallel misalignment between pump and motor shafts.
Bearing Defects: Early-stage inner race, outer race, ball, or cage damage (detected at specific fault frequencies).
Cavitation: High-frequency vibration from collapsing vapor bubbles.
Mechanical Looseness: From loose bolts, poor foundations, or bearing fits.
Resonance & Critical Speeds: Operating at a natural frequency of the system.
Bent Shaft: Creates a unique 1x and 2x running speed signature.
Our Analysis Process & Services:
1. Baseline & Routine Monitoring
Establish initial vibration signatures for new or repaired pumps.
Scheduled data collection (monthly/quarterly) using portable analyzers or permanent online sensors.
2. Advanced Diagnostic Analysis
Overall Vibration Level Trending: Tracks general machine condition.
Spectral (FFT) Analysis: Identifies specific fault frequencies.
Phase Analysis: Confirms imbalance, misalignment, or looseness.
Time Waveform Analysis: For impacting events like cavitation or rubbing.
3. Reporting & Corrective Actions
Clear, prioritized reports with:
Severity assessment per ISO 10816 standards.
Diagnosis of the specific fault.
Recommended corrective actions and timeline.
Root Cause Analysis to prevent recurrence.
4. Specialized Testing
Impact Testing (Bump Tests): To determine natural frequencies.
Start-up/Shutdown Coast-down Analysis: To identify resonance.
Post-Repair Verification: Confirming fault elimination after maintenance.
Benefits of Our Service:
Prevent Unplanned Downtime: Schedule repairs during planned outages.
Reduce Repair Costs: Fix small problems before they cause major damage.
Extend Bearing & Seal Life: Correct misalignment and imbalance reduces stress.
Optimize Maintenance Spending: Move from scheduled to condition-based maintenance.
Improve Energy Efficiency: A smooth-running pump consumes less power.
