Description:
Vibration Analysis III Textbook - Introduction
to Special Vibration Diagnostic Techniques & How to Analyze
Low, High and Variable Speed Machines
Part
Number VSA-3 (510 page seminar textbook) - $400
Highlights:
-
This
Analysis III seminar textbook provides in-depth coverage and
demonstrations of the diagnostic techniques introduced in "ANALYSIS
I and II" texts and also introduces techniques required
to continue effective program development.
-
Topics
in this text important for the optimization of any program include:
- (1)
"Time Waveform Analysis" shows how this important
technique can detect problems which will likely be missed
altogether by FFT analysis alone (as well as showing when
information contained within such waveforms can be used to
verify problem sources detected by spectral analysis). This
paper also covers the key procedures the analyst must employ
to specify important time waveform setup parameters (i.e.,
required sampling period (tMAX), recommended number of samples,
recommended vibration parameter (acceleration, velocity or
displacement) required to detect the problems for which he
is looking, etc.).
- (2)
"How to and How Not to Create Meaningful Narrowband Spectral
Envelope Alarms" covers theory on how they should be
established and includes real-world examples on how such envelope
alarms should be specified for different "families"
of machines.
- (3)
"How to Detect Problems Within DC Motors and Their Controls"
reveals surprising results of studies which found nearly 60%
of DC motor problems do not originate within the DC motor,
but instead within their controls and shows how to isolate
the source of the real problems using vibration analysis.
A series of real-world case histories are included.
- (4)
"How to Analyze Low Speed Machines" concentrates
on 10 to 300 RPM machines. This in-depth paper covers which
analyzers, transducers, measurement parameters and techniques
must be used to acquire meaningful data on these machines,
along with what measurement setups must be used. Case histories
illustrating how such techniques, analyzers and transducers
were employed on such low-speed machinery to detect and resolve
problems are included.
- (5)
"How to Analyze High Speed Machines" explains the
use of a completely different array of transducers, transducer
mounting techniques, analyzers, measurement parameters, etc.,
to effectively detect problems on this very different class
of machines. Real-world case histories are included which
were performed on machines generating fault frequencies exceeding
60,000 Hz (3,600,000 CPM).
- (6)
"How to Analyze Variable-Speed Machines" covers
how to effectively evaluate this unique family of machines,
both during a one-time diagnostics, as well as within a Condition
Monitoring Program. Instrumentation and techniques required
to ensure proper diagnostics on these special machine types
whose speed may change from one survey to the next, or might
literally change while measurements are being made are given.
Coverage on how to specify proper frequency spans, spectral
band alarms, #FFT lines, #averages, etc. is given, along with
real-world examples which illustrate how relatively small
changes in speed must be handled to properly evaluate machine
condition from one survey to the next.
- (7)
"High Frequency Enveloped Spectral Analysis Techniques"
includes detailed coverage of this relatively new condition
monitoring tool including key information pointing out differences
in various vendor approaches for each of the following:
- (a)
"Spike Energy Spectra"
- (b)
"Amplitude Demodulated Spectra"
- (c)
"Acceleration Enveloped Spectra"
-
(d) "SEE Spectra", showing how each of these
techniques can be effective by using proper band-pass and
high-pass filter choices, and how to interpret their spectral
results.
