Oil analysis, including Analytical Ferrography (A-Ferr), provides the greatest value for money of any maintenance monitoring technique. While most maintenance managers are familiar with the general concept of oil analysis, ferrography is oftentimes less understood.
Analytical Ferrography allows the oil analyst to go beyond the typical part per million (ppm) wear analysis of traditional oil analysis to actually determine the morphology of the wear particles present in the oil sample. A-Ferr reveals both the wear mode(s) present as well as the alloy compositions of the wear particles present. Interpretation of the ferrogram gives the analyst a clear picture of the component(s) that are wearing in the system.
In many instances A-Ferr is able to identify catastrophic wear modes, when typical ppm wear metals do not show any sign of the wear condition. A-Ferr can actually pinpoint specific component failure modes, thereby allowing maintenance to take action to avert a catastrophic equipment failure.
The WearCheck system is flexible allowing for the addition of analytical ferrography as either a one-off test on a questionable oil sample, as an automatic upgrade on any oil sample of concern, or as part of your on-going oil analysis testing package.
When utilized in conjunction with a regular oil analysis program, analytical ferrography provides the necessary information to make accurate and decisive maintenance decisions which can mean the difference between scheduled outage and repair versus costly major production losses.
