VA Cat I

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
