Delaware Analysis Training Classes
1)
Types of Vibration Monitoring
Programs - Discussion on the different types of vibration
monitoring programs and equipment requirements.
2) Program Development Procedures
- How to start a program and set realistic goals and objectives.
3) Monitoring Program Equipment
Reports - What reports should be provided to management for
justification of monitoring programs, thus providing a report card on
plant vibration program.
4) Basic Vibration Instrumentation
- Discussion of different types of equipment used in vibration analysis. Discussed are different
types of Sensors, Amplifiers, Recorders Data
Collectors and Multi Channel FFT Analyzers.
5) Data Collection – How to
setup data bases. An in-depth discussion of setting frequency ranges
(Fmax), measures required, sensors required and mounting techniques is
provided along with examples based on different types of equipment.
6) Vibration Basics (Calculation
of Frequency & Amplitude) - How the analyst uses the time
domain data to determine frequency and amplitudes from the time
waveform. This is an important concept for all analysts; especially
those who are responsible for analysis of Rolling Element Bearings and
Gearboxes. Exercises are provided for calculation of frequency and
amplitudes.
7) Data Collector and FFT Analyzer
Setups - How FFT analyzers work and what setups should be
utilized for specific applications to analyze problems.
6) Data Analysis -
How to analyze data in a logical step by step manner. Examples are used
to reinforce the presentation.
8) Balancing – Four Run no
Phase, Single Plane (Influence Coefficient and Measure Effect), Two
Plane and Multi-Plane Techniques are presented. Discussion of trial
weight selection and placement are presented. Problem exercises are
provided to reinforce presentations.
9) Balancing Turbines - How
to balance and determine influence coefficients for future balance
problems. Discussion of trial weight selection and placement based on
Bode and Nyquist plots are provided. Problem exercises are provided to
reinforce presentations.
10) Compromise Balancing -
How to counter balance thermal sensitivities in rotating equipment.
Problem exercises are provided to reinforce presentations.
11) Resonance & Critical Speed
Testing - Discussion on various methods to determine critical
speed and resonance problems are presented. Both Impact Testing and
Transient methods are discussed. Calculation of amplification factors
and options to reduce the vibration are provided. Demonstrations are
provided to reinforce the presentations.
12) Modal Testing & Operating
Deflection Shapes - How to conduct a single degree of freedom
Modal Analysis by plotting the Real and Imaginary Components is
presented. Demonstrations utilizing impact hammers to develop the mode
shapes are presented. The development of Operating Deflection shapes is
presented by discussing both single and multi-channel instrumentation.
13) Portable Tape Recorders and
their Application - How to use tape recorders and how to choose
the correct channels (FM or DR) to utilize for recording. Analog and
Digital Tape recorders are discussed. Demonstrations on there
applications are provided.
14) Sources of Vibration -
Different types of vibration problems (i.e. Alignment, Balance,
Looseness, Gearmesh, Pump Flow, etc.), the frequencies generated, how
they are generated and direction of the vibration along with symptoms
are discussed. Examples of each problem type are discussed and example
plots are provided.
15) Turbine Generator Trending and
Analysis - What vibration parameters should be trended along
with what external parameters influence vibration problems.
16) Pump Trending and Analysis
- What vibration parameters should be trended and what to look for in
the vibration data.
17) Motor Analysis - What
to look for and how to do a quick check and determine if there is an
electrical or mechanical problem.
18) Gearbox Trending and Analysis
- Frequency calculation and analysis
are discussed.
19) Analysis of Motors & Pumps
(Case Histories) - Discussion of different types of problems
encountered, how the analysis was performed, what equipment was
utilized and how the conclusions were drawn.

Histories) - Discussion of different types of problems
encountered, how the analysis was performed, what equipment was
utilized and how the conclusions were drawn.
22) Economic Justification of
Vibration Programs - Calculations using interest rates, cost of
money and rate of return to justify program equipment.
