How to Diagnose the Root Cause of an Overheated Gearbox

This session will show you how to find commonly misdiagnosed or overlooked issues. A case-study example of a medium-sized gearbox with a seemingly obvious lubricant failure will be presented to illustrate how data can identify a lubricant selection problem. Attendees will learn how to apply this knowledge to future oil analysis reports so they can correctly diagnose the true root cause of an alarmed condition.

Measuring Varnish Potential in Lube Oil

Lubricating oil in gas turbines and hydraulic systems is unfortunately subject to the ravages of varnish. It is well-documented that varnish is an insoluble contaminant comprised of oil degradation by-products and sometimes depleted additive molecules..

What Failed Demulsibility Results Mean

Lubricants and water have a natural tendency to separate because most basestock molecules are non-polar, while water molecules are polar and will seek each other out instead of mixing with the basestock..

Interpret Reports in the Time it Takes to Brush Your Teeth

This webinar will provide an unconventional approach to quickly decipher all the information on a report in 2 minutes or less, using real examples, to encourage the reading of every report (not just those alarmed as critical).

Attendees will learn a new skill to save time reading reports, while bringing their oil analysis out of a reactive maintenance mode and back into a truly predictive maintenance mode...

Setting Acid Number and Base Number Limits

There is a rule-of-thumb that oil should be condemned at double its new oil Acid Number, or at half of its new oil Base Number. The problem with this rule is that is has too many exceptions to be valid. Rather than identify the valid instances, it is better to understand how to derive a correct limit for any application..

Understanding ISO Codes

Why are we so concerned about particulate in oil? The ISO codes, according to the ISO 4406:1999 standard, relate to only three different ranges of particles, ≥4 µm/≥6 µm/≥14 µm.........

Variability in Oil Analysis Results

Two consecutive samples, at normal sampling intervals from the same machine, are never expected to have exactly the same results, but occasionally the second set of results appears to have either changed...
