Vibration Analysis Category I
VA Cat 1 personnel are qualified to perform a range of simple single-channel machinery vibration condition monitoring and diagnostics of machines
activities in accordance with ISO 17359 and ISO 13373-1. They are qualified to: □ know of the basic principles of vibration and recognize the different units of measurement □ be able to collect reliable data ensuring appropriate standards of repeatability □ be able to identify errors in collected data □ be able to retrieve pre-defined measurement settings for use with VA equipment and transfer data from an analysis system to a computer-based system □ be able to compare overall or single-value vibration measurements against pre-established alert settings
□ be able to identify deviations from the norm for single-value vibration values and trends
□ report on visual observations of equipment condition
VA Category I - Course Content:
This course has a dedicated workbook based on the ISO 18436-2:2014 certification program for vibration analyst category I & is designed to
prepare staff for the BINDT PCN VA Cat I Certification Exam. The course is accredited to BINDT PCN CM GEN App D. The following is covered:
Day 1 Introduction
Introduction to condition monitoring and simple failure mode analysis. □ Task 1: Selecting CM Techniques
Principles of Vibration Basic motion: Period, frequency, amplitude (peak, peak-to-peak, r.m.s.). Parameters (displacement, velocity, acceleration). Units, unit conversions, time & frequency
domains. □ Task 2: Measuring Velocity □ Task 3: Vibration Waveform Examples (3†) □ Task 4: Vibration Waveform Descriptors
Introduction to Resonance Methods of finding and avoiding/reducing resonance. □ Task 5: Identifying Resonance □ Task 6: Case History – Main Circ. Pumps
Day 2 Data Acquisition – Instrumentation
Instrumentation, transducer types, locations & mounting. □ Task 7: Choice of Monitoring System
□ Task 8: Recognising Transducer Types Data Acquisition – Measurement
Overall vibration, vibration severity, setting alarms and □ Task 9: Vibration Severity Exercises (6†) □ Task 10: Broadband Vibration Fault Exercise □ Task 11: Setting up & Taking Measurements Recognising Poor Data □ Task 12: Recognising Invalid Readings (4†)
Day 3 Monitoring Program Set-up Recognize AC induction motor,
basic pump & fan combinations. Centrifugal & screw compressors, rolling mills, paper machines, process equipment, machine tools and simple gearboxes. □ Task 13: Allocating Measurement Points □ Task 14: Identifying Machine Components □ Task 15: Recognising Asset Types Vibration Frequency & Signal Analysis Be
aware of the term FFT and recognize the following basic FFT terminology: e.g. number of lines, Fmax and time to sample. Recognize basic faults, e.g. bearing noise and damage, balance, looseness and misalignment.
□ Task 16: Recognising Common Faults (3†)
Day 4 Frequency & Signal Analysis – Fault Finding
Recognize fault frequencies for pre-set FFT and simple time waveforms for unbalance, looseness, misalignment, bearing noise & damage. Be aware of simple maintenance actions to rectify faults, e.g. lubrication
and alignment □ Task 17: Vibration Frequency Analysis (8†) □ Task 18: Case History – Ball Mill Course Assessment Course Review & Training Examination Optional BINDT PCN VA Cat 1 Exam*
* This can be arranged through SpectrumCBM or any other BINDT Approved Examination Centre (AEC) * Applications should be made to BINDT at least 2 working weeks before the exam date Note: The BINDT PCN VA Level
1 Exam may be taken immediately after the training, but the certificate will only be awarded after 6 months relevant logged VA experience. † Number of examples in the particular task - Note: There are 16 Tasks with a total of 30 Examples
