Vibration Analysis

Vibration Analysis

All rotating machinery generates vibration. Knowing how much is too much, and finding and correcting the source of any excessive vibration before it causes damage. Vibration Monitoring can be a very effective part of your Predictive Maintenance Program (PdM) and an integral part of an overall Conditioned based Maintenance (CbM) approach.

Rotating machinery can have flaws undetectable through human means. These flaws can cause a significant reduction in machinery efficiency and lifespan, negatively affecting production, equipment operations and maintenance costs. Incorporating vibration monitoring inspections into your Conditioned based Maintenance program can ensure your equipment is operating as designed.

The Vibration Monitoring Process

The process begins by identifying critical assets and their effects on production through our custom designed criticality tool. Based on the equipment identified and the manufacturer's recommended operational parameters, a proper frequency of vibration monitoring can be obtained. Once created, field technicians will routinely come to your facility to conduct the vibration monitoring to ensure proper data collection.

The vibration monitoring and analysis from the machinery will allow for timely detection and repair of such operational issues and flaws as:

  • Failing Bearings
  • Unbalances
  • Misalignments
  • Gear Problems
  • Electrical Problems
  • Out-of-Round Journals
  • Bent Shafts
  • Looseness
  • Impeller Problems
  • PLUS many other causes
Early detection of mechanical fatigue and breakdown

All rotating equipment vibrates to some degree, but as older bearings and components reach the end of their product life they begin to vibrate more dramatically, and in distinct ways.

Ongoing monitoring of equipment allows these signs of wear and damage to be identified well before the damage becomes an expensive problem.

Accurately monitor the health of your plant machinery

Arrelic portable and permanently-mounted vibration analyzers are used in this monitoring process. Our vibration analyzers record machine vibrations using sensors such as accelerometers and tachometers.

Accelerometers are the ‘ears’ of our instruments, and are connected to rotating machinery such as electro-mechanical drives and gearboxes. The vibrations and movements of the equipment are then recorded.

Decrease downtime and increase savings

This process is generically known as ‘condition monitoring’. When used correctly, it can result in huge cost savings when compared to traditional maintenance methods.

Traditional maintenance methods are preventive: components are replaced on a fixed schedule whether worn or not; and reactive maintenance: in which components are repaired only after they have broken down.

Neither of these methods is ideal, although both are very common throughout the heavy industry sector, and both tend to incur much higher costs than those methods that use vibration analysis.
