ANALYSIS III - INTRODUCTION TO SPECIAL VIBRATION ANALYSIS TECHNIQUES AND NARROWBAND SPECTRAL ENVELOPE ALARMS This seminar builds from ANALYSIS II and is intended for analysts having approximately 1 to 2 years experience. It includes in-depth coverage and demonstrations of the diagnostic techniques initially introduced in ANALYSIS II and covers additional diagnostic techniques required to improve PdM program effectiveness. Topics in this seminar important for the optimization of any program include: "Time Waveform Diagnostic Analysis" shows how this important technique can detect problems which likely will be missed altogether by FFT analysis alone (and can verify problem sources that are detected by FFT analysis). Coverage is included on how to specify key time waveform setup parameters (required sampling period (tMAX), recommended number of samples, and recommended vibration parameter). "How to and How Not to Create Meaningful Narrowband Spectral Envelope Alarms" clearly demonstrates how such narrowband alarms should be established, as well as real-world examples on how such envelope alarms should be specified for different "families" of machines. "High Frequency Demodulated Spectral Analysis" using a variety of data collection systems to detect rolling element bearing, gear, electrical, lubrication and rotor rub problems is provided. "How to Detect Problems Within DC Motors and Their Controls" reveals surprising results of a 3-year study which found nearly 60% of DC motor problems do not originate within the DC motor, but instead in their controls and shows how to determine the source of the problem(s). "How to Analyze Low Speed Machines" concentrates on 10 to 300 RPM machines, along with what analyzers, transducers, measurement parameters and techniques must be used to acquire meaningful data on these machines, along with required measurement setups which must be used. Case histories illustrating how such techniques, analyzers and transducers were employed to detect and resolve problems on real-world, low speed machines are included. "How to Analyze High Speed Machines" explains the use of a completely different array of transducers, transducer mounting techniques, analyzers, measurement parameters, etc. in order to reliably evaluate the condition of machines which generate forcing frequencies above 10,000 Hz (600,000 CPM). "How to Analyze Variable-Speed Machines" covers how these machines should be analyzed both during a one-time diagnostics, as well as within a Condition Monitoring Program. Instrumentation and techniques required to ensure proper diagnostics on these variable-speed machine types whose RPM may change significantly from one survey to the next, or literally change while measurements are being made, is given including how to specify proper frequency spans, spectral band alarms, #FFT lines, #averages, etc. Real-world examples clearly illustrate how relatively small changes in speed must be handled to properly evaluate machine condition from one survey to the next. "Motor Current Signature Analysis" focuses on how this tool can be effectively used along with vibration analysis to confirm the presence and severity of faults within induction motors. This includes detection of problems with the stator, rotor and dynamic/static eccentricity. ANALYSIS III SEMINAR AGENDA INTRODUCTION TO SPECIAL VIBRATION ANALYSIS TECHNIQUES
