Air-cooled chiller dynamic vibration analysis

Air-Cooled Chiller Dynamic Vibration Analysis | Enhance Performance with EKG (Malaysia) Sdn Bhd

Why Dynamic Vibration Analysis Is Important

• Detects issues under real operating conditions

• Identifies problems that don't appear during idle or low-load states

• Reveals load-induced faults such as structural resonance or unbalanced forces

• Prevents unexpected failures and improves reliability

• Supports precision maintenance and long-term asset planning

Key Areas Analyzed

• Compressor movement and motor shaft alignment

• Fan blade balance and bearing wear

• Frame, base, and structural resonance

• Coupling and gearbox performance (if applicable)

• Vibration response to load changes

Our Dynamic Vibration Analysis Process

• Sensor Installation and Setup
  We mount triaxial accelerometers and velocity sensors on critical components to capture multidirectional vibration under varying load conditions.

• Real-Time Data Collection
  Sensors collect data during actual chiller operation—capturing fluctuations in frequency, amplitude, and displacement as the load varies.

• Advanced Signal Processing
  Using tools like Fast Fourier Transform (FFT), time waveform analysis, and order tracking, we isolate vibration signatures that indicate:

  • Looseness or rotor imbalance

  • Misalignment between motor and compressor shafts

  • Dynamic resonance affecting structural components

  • Harmonic distortion from fan or motor irregularities

• Comprehensive Reporting
  We provide a detailed report with:

  • Dynamic vibration readings at multiple load points

  • Root cause analysis of anomalies

  • Severity ratings

  • Recommendations for corrective actions (rebalancing, realignment, bearing replacement, etc.)

Benefits of Dynamic Vibration Analysis

• Provides accurate, load-specific fault detection

• Uncovers issues that static testing may miss

• Helps prevent critical mechanical failures

• Improves chiller performance and energy efficiency

• Reduces unplanned downtime and repair costs
