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
