LESSONS IN LUBRICATION narrowing down their probable sources (internal or external), oil analysis can help answer questions such as: • Is the oil clean? • What types of contaminants are in the oil? asked to the patient. Likewise, with oil analysis, careful oil samples are taken, and elaborate machines yield the test results. Laboratory personnel interpret the data to the best of their ability, but without crucial details about the machine, a diagnosis or prognosis can potentially be inaccurate. Some of these important details include: • Where are contaminants originating? • The machine's environmental conditions (extreme temperatures, high humidity, high vibration, etc.) • Are there signs of other types of lubricants? • The originating component (steam turbine, pump, etc.), make, model and oil type currently in use • Is there any indication of internal leakage? Wear Debris • The permanent component ID and exact sample port location This form of oil analysis is about determining the presence and identification of particles produced as a result of mechanical wear, corrosion or other machine surface degradation. It answers a number of questions relating to wear, including: • Proper sampling procedures to confirm a consistently representative sample • Occurrences of oil changes or makeup oil added, as well as the quantity of makeup oil since the last oil change • Is the machine degrading abnormally? • Whether filter carts have been in use between oil samples • Is wear debris produced? • Total operating time on the sampled component since it was purchased or overhauled • From which internal component is the wear likely originating? • What is the wear mode and cause? • Total runtime on the oil since the last change • How severe is the wear condition? Ultimately, you need to know if any actions should be taken to keep the machine healthy and to extend the life of the oil. Oil analysis for machines can be compared to blood analysis for the human body. When a doctor pulls a blood sample, he puts it through a lineup of analysis machines, carefully studies the results and reports his conclusions based on his education, research and detailed questions • Any other unusual or noteworthy activity involving the machine that could influence changes to the lubricant Oil Analysis Tests For a standard piece of equipment undergoing the normal recommended oil analysis, the test slate would consist of "routine" tests.
