Accurate Vibration Analysis

Vibration analysis is used primarily with rotating equipment to find
problems such as misalignment, out-of-balance conditions, and bearing
defects. Prior to using vibration analysis, maintenance technicians
had to wait until a bearing failed to realize there was a problem.
Using vibration analysis, however, periodic readings are taken and
recorded. Maintenance personnel then compare these readings to a
baseline. When wear reaches a certain level, the bearing is scheduled
for replacement, before it fails. This reduces the amount of reactive
maintenance and ensures the replacement occurs with minimum impact on
the production or facility schedule.

Other applications include extending vibration analysis to other
kinds of mechanical components. For example, some maintenance departments
have used vibration analysis to help in isolating problems with belts and
sheaves. We also have used the technology on gear drives to help find
defects or rapid wear problems. And we have even used vibration analysis
to monitor non-mechanical problems in fluid power systems, for example.
Restrictions or disturbances in a fluid handling system creates turbulence
and unique vibration signatures that can help identify the problem.
Vibration readings are recorded on machinery and downloaded into a computer.
The data is reviewed by a trained analyst that has a background in each
customer specific industry. The detailed reports may be generated
on site and provide immediate information regarding machine problems.
Using vibration analysis, bearing defects can be detected several months
before it affects machine operation. Additionally, machine deficiencies
such as misalignment, unbalance and belt problems can be detected and
corrected before they cause bearing damage, or failure.
