Elements of an Oil Analysis Program
Whenever a proactive maintenance strategy is applied, three steps are necessary to insure that its benefits are achieved. Since proactive maintenance, by definition, involves continuous monitoring and controlling of machine failure root causes, the first step is simply to set a target. or standard, associated with each root cause.

Fundamentals Of Fluid Analysis for Industrial Machinery
Every industrial organization has experienced the consequences of shoddy maintenance: contract penalties, junked parts, injuries, catastrophic damage, ballooning costs, missed shipping dates, irate customers, and sickly quarterly financial reports. Today, machinery and equipment can be maintained to achieve useful operating lives many times those attainable just a few years ago. For oil lubricated machinery, the… Read More

Tricks to Classifying Wear Metals and Other Used Oil Suspensions
The most common methods for initial detection of abnormal levels of wear debris in used oils include elemental analysis, ferrous density analysis (DR, etc.), particle counting and patch testing. For some users, because of the criticality of the application, all of these screening tests for wear metals are integrated into the routine test slate. Read More

Analysis of In-Service Automotive Engine Oils
Most oil analysis performed in North America is done on diesel engine crankcase oils, primarily for large fleets in the transportation and off-road equipment industries. Ranking second would be the analysis of lubricants used in stationary industrial machinery including compressors, turbines, gearing, bearing lubes, and hydraulics. Far down the list is engine oil analysis performed… Read More

Successful Oil Analysis Practices in the Industrial Plant
Every industrial organization has experienced the consequences of shoddy maintenance: contract penalties, junked parts, injuries, catastrophic damage, ballooning costs, missed shipping dates, irate customers, and sickly quarterly financial reports. Gone are the days when a machine had a predictable service life, after which it was replaced, continuing the cycle. Today, machinery and equipment can be… Read More

The Power of the Patch (Comparing particle analysis methods using membranes)
The practice of transferring suspended particles to the surface of a membrane for analysis has been around for decades. It is perhaps the earliest method for inspecting solid contaminants and wear debris in a used sample of oil. It is of no surprise that these methods have enduring use today. In fact, some are the… Read More

Looking Through the Eyes of Onsite Contaminant Monitors
Without the lens of a microscope, bacteria and viruses might only be recognized as painful symptoms of sickness and disease by those who are infected. Just as technology is an important enabler in human pathology, it also serves in the detection and diagnosis of a host of machine health issues, including the invasion of lubricant… Read More
