i-ALERT2 Application Guide

If process data is available from the control system it should be overlaid with the vibration/temperature trends of the i-
ALERT2
to help determine root cause. Often the root cause of a vibration problem is a process upset.
STEP 3.RESOLVE: CORRECTION AND IMPROVEMENT
After determining the root cause of the problem, it can be
corrected. Cost effective corrective actions will depend on the
machine in question and the findings of the failure analysis. In
order to maximize the reliability of the machine in question, it is
also advisable to improve the vibration levels on the machine to
“precision state” levels after it has been repaired. This will extend
the life of the machine.
STEP 4.DOCUMENT
After determining the root cause of the problem, correcting the problem and improving the machine, it is important to
verify
that the correction/improvement has occurred and document the findings. One mechanism for this verification is
comparing the vibration levels after restarting the machine with those taken before shutdown and the original baseline
data. Other common verification methods include:
o
Measuring reduced energy consumption
o
Capturing Infrared Thermography Images
o
Oil analysis
o
Confirming precision alignment
