In industrial plants (cement, steel, F&B,…), a lot of rotating machineries are used such as: motor, fan, pump, compressor, gearbox,… and are applying a periodic/preventive maintenance program or unscheduled repair (run to fail) maintenance. However, these maintenance programs are not cost-effective, increases spare parts, and does not optimize machinery life. The CBM (Condition Based Maintenance) program will overcome this disadvantage, increase reliability and prevent serious damage. Among the CBM diagnostic technologies, vibration analysis is currently the most.

Benefits

  • Early detection of abnormalities: fan/pump imbalance, bearing damage, etc.
  • Increase the efficiency of the maintenance program: proactively plan maintenance, replacement, spare parts based on vibration measurement results.
  • Optimize operating performance: detect and fix damage early to avoid interruption of the production process.

Technological ability

Monitor and evaluate overall vibration levels according to ISO 20816-3 and Technical Associates of Charlotte to detect abnormalities and trends in the deterioration of rotating machinery with an intuitive interface.

In addition to monitoring overall values over a wide frequency range as above standard (0 – 1000 or 2000Hz), we also use spectral band alarms to easily monitor and detect damaged components such as bearings, gears, fans, electrical problems, etc.

Analyze frequency spectra and time domain spectra to determine mechanical failure conditions such as: unbalance, misalignment, bearing/gear failure, etc.

Perform advanced analysis as needed:

  • Phase analysis: to determine the cause of vibration when there are similar patterns on the spectrum such as imbalance, misalignment, weak foundation.
  • Bump test: determine the natural frequency of the machinery to check the resonance frequency.
