If you attend the Reliability Maintenance Solutions Ltd Training Institution Public Vibration Cat 2 course, you will also get a copy of the book of gold as part of your package https://rms-reliability.com/product/cat-ii-vibration-analysis/
In this case study we show that by measuring the correct vibration parameters you can resolve defects in harsh applications, even an inner raceway defect on a vibrating screen. Hopefully, you are finding them of use and helpful.
Here is the third of the five case studies brought to you with the Reliability Training Institute. In this case study we show how vibration analysis detected a hidden failure in a variable frequency drive. Hopefully, you are finding them of use and helpful.
As promised and to follow up on my previous post on bearing failures here is the first of five technical detailed case studies presentation. This is my first voice over presentation so please excuse the English Farmer accent mixed in with some Australian twang.
Hello everyone, I have created short presentation to share some different bearing failures that were detected before function failure. This has been put together for meetings and toolbox talks to promote the benefits of what defects a condition monitoring program can detect. Every bearing here has a story of how it was detected and what actions were/were not put in place to protect the functionability of the system.
This is aimed to highlight (at a high level) to management and production what we can detect if a suitable system is set up correctly.
I am working on another case study presentation that follows up on these and some other cases. In this one it will have the technical testing data (thermal, electrical and vibration) and a full case study also showing the ‘The Cause’ ‘The Mechanism of Failure’ and ‘The Failure Mode’. This will be posted over 5 videos.
Please feel free to share and spread the knowledge
Apologies for the lack of posts, work and life has been busy but fun, now back to my hobby.
Whilst going though some of my files I found a spreadsheet I wrote first back in 2012/2013 (ish). I thought it would be a good spreadsheet to share.
The reason I created this spreadsheet was that in my job at the time I had to create Vibration Standards for database creation/standardisation across multiple business units and locations, and so I needed a quick way to decide upon the best data collection parameters that would resolve the defect of interest. There was also limited server space so I didn’t want to collect unnecessary data. Obviously, now with the advance in technology you can take one large data set with huge number of samples and a high sample rate.
The spreadsheet is self explanatory and has notes on each section to explain, please read the ‘Introduction’ tab first. Even though it was designed for the CSI Emerson MHM the ‘Vibration Calculator’ tab is universal (other than the Special time waveform option) whereas the ‘PeakVue Calculator’ tab is unique to CSI MHM.
This interactive calculator is good to help understand how the sample rate and number of samples affects the frequency and time domain resolution for what you want to resolve.
Apologies in advance on any terminology errors as I wrote this in the English/Aussie tongue, therefore there may be some miss interpretation from my English/Aussie to other cultures.
