Description:
57 page Booklet on Proven Method for Specifying Both Six Spectral
Alarm Bands as well as Narrowband Alarm Envelopes using today's
Predictive Maintenance Software Systems
(4th Edition)
Part
Number SAB-4 (57 page booklet) - $79
Highlights:
-
This
widely read paper provides answers to two critical steps in
the setup of a condition monitoring database
-
How to properly specify important spectral parameters for
a variety of machinery operating at a wide range of speeds
(i.e., frequency range, #FFT lines, #averages, etc.)
-
how
to properly specify the alarm limits for a number of frequency
bands that are used to divide up the spectrum frequency
span into a series of frequency segments, each of which
cover specific frequency locations where certain problems
occur (i.e., unbalance, bearing faults, gear problems, blade
pass, electrical problems, etc.).
-
Properly
specified spectral alarm bands allow the analyst the ability
not only to detect the presence of such problems, but also give
him time to react and take the required corrective measures
before potential catastrophic failure.
-
These
documented methods (which were developed over the past 15 years
by implementing a series of predictive maintenance programs
on a broad range of machinery) have greatly enhanced the effectiveness
of condition monitoring programs by allowing analysts to concentrate
their efforts on the machines truly in need of attention.
-
This
paper will provide examples on how to refine spectral band alarm
limits statistically after a number of surveys have been taken.
-
It
will also help the analyst to determine on which machines to
apply narrowband alarms rather than (or in addition to) spectral
band alarms.
-
The
information in this paper can greatly enhance both new and existing
condition monitoring programs by ensuring that both the measurement
parameters and the alarm levels are properly specified for each
of the spectra to be taken.
