I have put together a 4 page document to explain why I wrote my book and also what the content is. Please download the PDF below and have a look.

Enhancing System Reliability Through Vibration Technology – The Book. UPDATE!!

We have managed to secure discounted postage with the printing company direct, this update has the new reduced postage costs.

ISBN: 978-1-5272-5386-5

This technical reference book comprises of over 20 years’ experience in the fields of Vibration Analysis, Condition Monitoring and Reliability Engineering. It is written with the technical tradesperson in mind, interpreting Vibration principles into layman’s terms. It has taken 7 years to fine tune the book and I have been though three demo versions. This is the first published version.

All data is from real-life situations with over 20 case studies throughout the book. This is to be used as material to help support knowledge sharing, practical training and mentoring to enhance System Reliability though Vibration technology

The Seasoned Analyst

Pump Flow issue detected through PeakVue

Background:

During an asset assessment survey of a Pump Set we detected an anomaly in the vibration data.

This is a ‘Brook Crompton Parkinson’ motor D112 Frame, 2865 RPM, 50Hz 3 Phase, 415V 4.9A with and integral ‘APE-Lee Howl Limited’ pump end.

Image 1 is of the pump set, this is a circulation pump for a water system.

Image 1:

Pump Set

Analysis:

Using experience, the human sense and the vibration data the conclusion was that there is a flow related issue.

 

Vibration Data:

Figure 1 is the Autocorrelation of the pump end PeakVue data in a circular plot.

Fig 1:

Figure 1.

This data shows the abnormal ‘wobble’ operation of the pump and that for each revolution there are three restrictions in the motion.

 

Inspection:

On visual inspection of the pump system it was found that the pump supply valve was closed. This was opened and water was then allowed thought the pump.

 

Follow up Vibration:

Figure 2 is the same PeakVue data as before but now with the pump system in its correct operational state.

Figure 2.

This data now shows the smooth circular motion of the pump.

 

Summary:

This case study brings a few things to mind

  1. The most important part of any program is the person performing the data collection and analysis
  2. When all else fails, leave the air conditioning, and go examine the operating equipment. Go look, touch, feel, smell and listen to the machinery

Pearls of Wisdom

I have been privileged and blessed to have experienced varied fields of Vibration Analysis, Condition Monitoring and Reliability, and had the opportunity to study under some of the great mentors and trainers in these discipline. I feel it is always good to share knowledge and learnings to help others who want to progress and to promote our discipline.

Often people discuss what makes a good vibration analyst? – electrical or mechanical background – degree or apprenticeship level, certification or experience……….. Then when we find an issue we always get asked “How long will it last?”, and our answer to this question, I feel, greatly depends on our experience and training.

In the discussions I have had with many other people, we have all spoken ‘Pearls of Wisdom’. The 14 statements below I feel are very important in the way we operate in our discipline.

1) The most important part of any program is the person performing the data collection and analysis.

2) The second most important part of any program is the training and mentoring given to the person selected.

3) 5 years of experience is not the same as 1 year of experience 5 times.

4) The most important question you can ever ask is “why”.

5) It is important to understand the values of the numbers you are using.

6) Physics of the machine is really important.

7) You can’t analyse what you don’t know or understand.

8) A person may not be stupid, they may just not understand what you are saying.

9) 1 times RPM is not always unbalance.

10) There are no universal vibration severity limits.

11) Absolute amplitude in the frequency domain is relatively useless. Don’t forget the time domain & phase.

12) There are no ghost frequencies or unknown frequencies but only frequencies not analysed enough.

13) Don’t ignore the potential benefits of chit chat in the crib/break room with the operators and maintenance teams. They know their machines!

14) When all else fails, leave the air conditioning, and go examine the operating equipment. Go look, touch, feel, smell and listen to the machinery.

Please share and if you have anymore ‘Pearls of Wisdom’ let everyone know.
