Electronic vibration analysis is the only means of detecting some impending problems that can lead to sudden and complete failure. Manufacturers of vane-axial fans and centrifugal chillers recommend vibration analysis be performed during routine maintenance in order to assure reliable and safe operation.
Vibration analysis will detect any imbalance in rotating members such as fans and impellers.
The electronic testing equipment will establish how much weight to add and where to add it in order to bring a piece of rotating equipment back into proper balance.
Vibration analysis used as a maintenance tool, measures vibration intensity over a predetermined period of time. This information is useful in deciding when equipment must be shut down for repairs.
