Vibration Analysis

The condition and health of a machine can be measured by using vibration analysis

Vibration analysis refers to the process of measuring the vibration levels and frequencies of industrial machinery, and using that information to determine the health of a machine and it's components.

The vibration characteristics of a rotating machine are measured and recorded using an accelerometer.  An accelerometer generates a voltage signal, proportional to the amount of vibration, as well as the frequency of vibration, or how many times per second or minutes the vibration takes place.

This voltage signal from the accelerometer is fed into a data collector, which records this signal as either a time waveform (amplitude vs. time), as a Fast Fourier Transform (amplitude vs. frequency), or as both. This signal can then be analysed to determine any impending problems in the machine. 

Data gathered by our certified technicians is analysed and through rapid interpretation of detailed reports we are able to recommend corrective action to successfully improve your maintenance and reliability performance.

The Common Problems:

- Unbalance

- Misalignment

- Bent shaft

- Loose components

- Malfunction of machinery

- Downtime on production

We Provide the following Solutions:

- Identification of issues prior to downtime and loss of production

- Reduction of damage to secondary equipment

- Improved equipment reliability and production
- Prioritisation of required maintenance through detailed reports. 

Vibration Analysis can detect the following:

  • Bearing defects
  • Lack of lubrication
  • Over-lubrication
  • Mechanical Looseness
  • Structural Looseness
  • Misalignment
  • Unbalanced and/or cracked shaft
  • Structural resonance
  • Piping resonance
  • Pitting of race and ball/ roller
  • Spalling
  • Eccentric journals
  • Unbalanced magnetic pulls
  • Blade resonance
  • Broken/ damaged rotor bars
  • Structural and foundation faults
  • Air gap geometry variations
  • Vortex shedding
  • Broken, cracked and misaligned gears
  • Cracked and/or worn teeth
  • Eccentric gear
  • Rolling element bearings
