Vibration Analysis in Predictive Maintenance
|
|
|
|
|
Accurate
vibration analysis can be the most valuable maintenance tool
available. When used properly, it can provide the necessary
information to completely evaluate machine condition, identify
symptoms to avoid ongoing damage, determine the cause of damaged
components and offer a prognosis for remaining service life. It
can mean the difference between maximum production efficiency and
catastrophic failure.
We begin this two-day program studying
the modern methods used throughout the industry to effectively
evaluate machine vibration, how it effects equipment, and how to
identify an unbalance,
misalignment, or bearing problem.

Who should attend:
This course is of interest to anyone
involved with identifying and correcting faults in rotating
machinery including plant managers, maintenance supervisors and
field technicians. An engineering degree is not required, but a
general working knowledge of machinery and equipment is
recommended.
