Chiller Pump Vibration Analysis Services | Predictive Diagnostics by EKG (Malaysia) Sdn Bhd
Detect Problems Before They Cause Costly Failure
Vibration analysis is the most effective predictive maintenance tool for chiller pumps, identifying mechanical issues at their earliest stages—long before they lead to catastrophic failure, unplanned downtime, or inefficient operation. EKG (Malaysia) Sdn Bhd provides professional vibration analysis services using advanced diagnostic equipment to monitor the health of your critical chiller circulation pumps, ensuring they operate smoothly, efficiently, and reliably.
Early Fault Detection: Identifies imbalance, misalignment, bearing wear, and cavitation months before traditional methods.
Prevent Unplanned Downtime: Avoids costly chiller plant shutdowns during peak cooling periods.
Maintain Energy Efficiency: A vibrating pump consumes more energy; early correction restores optimal efficiency.
Extend Equipment Life: Prevents progressive damage to shafts, bearings, seals, and couplings.
Safety Assurance: Detects developing faults that could lead to catastrophic mechanical failure.
We follow ISO 10816 and ANSI/ASA S2.71 standards for vibration severity assessment.
1. Data Collection & Baseline Establishment
Our certified technicians use portable vibration analyzers with tri-axial sensors.
We take measurements at critical points: pump and motor bearings (horizontal, vertical, axial).
We establish a baseline vibration signature for each pump during normal operation.
2. Advanced Diagnostic Analysis
We analyze multiple parameters to pinpoint specific faults:
Overall Vibration Velocity (mm/s): Indicates general mechanical condition and severity.
Frequency Spectrum Analysis: Identifies the root cause of vibration by separating complex vibration into individual frequency components:
1x RPM Frequency: Indicates unbalance.
2x RPM Frequency: Indicates misalignment.
Bearing Frequencies: Indicates bearing defects (inner/outer race, balls, cage).
Vane Pass Frequency: Indicates impeller issues.
High-Frequency Noise: Indicates cavitation or lubrication issues.
3. Detailed Reporting & Severity Assessment
We provide a clear, actionable report including:
Vibration Severity Chart: Showing whether each measurement point is in Good, Satisfactory, Unsatisfactory, or Unacceptable condition.
Diagnosis: Specific identified faults (e.g., "Moderate misalignment at pump coupling," "Early-stage bearing wear on motor DE").
Trend Analysis: Comparison with previous readings to show fault progression.
Spectrum & Waveform Plots: Graphical evidence of the fault conditions.
Corrective Action Recommendations: Specific steps to resolve the issues, such as:
Schedule laser alignment.
Plan bearing replacement.
Check for impeller clogging or damage.
Verify foundation and baseplate integrity.
Misalignment (Parallel & Angular): The #1 cause of premature bearing and seal failure.
Unbalance (Impeller or Coupling): Causes excessive force on bearings.
Bearing Defects: Inner race, outer race, ball, or cage damage.
Mechanical Looseness: From worn base bolts, bad bearings, or poor fit.
Cavitation: Detected as high-frequency "noise" in the spectrum.
Resonance & Structural Issues: Where the pump's vibration frequency matches the natural frequency of its support structure.
One-Time Diagnostic Survey: Ideal for troubleshooting a specific problem or establishing a baseline.
Quarterly/Bi-Annual Periodic Monitoring: Scheduled visits to track pump condition and catch developing faults.
Continuous Online Monitoring: Installation of permanent sensors for 24/7 vibration tracking of mission-critical pumps, with real-time alerts.
Certified Technicians: Trained in vibration analysis and pump mechanics.
Advanced Diagnostic Equipment: We use state-of-the-art analyzers from leading brands.
HVAC-Specific Expertise: We understand chiller pump operating environments and common failure modes.
Actionable Reporting: We don't just provide data—we give clear, prioritized recommendations.
Corrective Action Support: We can perform the recommended alignments or repairs, or work with your maintenance team.
Routinely: Every 3-6 months for critical chiller pumps.
After Repair or Installation: To verify correct alignment and assembly.
When Unusual Noises or Vibrations are Noticed.
