How to correctly interpret the results of oil analysis. Spectro scientific Any diagnosis only brings results when there are specialists who can correctly explain the data obtained. Otherwise, it may lead to unnecessary repairs or to skipping the problem. You can look for a problem where it does n ... ot exist. Consider one such example when the analysis of the oil was incorrectly interpreted: a sample was taken from a gas engine and its elemental analysis was performed. As a result, increased values of copper and lead were obtained. And using only this data, the staff decided to dismantle the engine in order to check some parts and bearings. And this check showed that the engine has no abnormal wear. Of course, the user was disappointed in the analysis of oil as a method for diagnosing equipment problems. However, there is a misinterpretation of the data, a lack of an integrated approach to the results of oil analysis and a complete misunderstanding of tribology. The user knew that the presence of copper and lead in the oil analysis report indicated bearing wear. However, to draw a similar conclusion on one oil sample is not entirely correct. Before starting to diagnose the engine for oil analysis and data interpretation, and even more so to disassemble it, you should pay attention to several questions: - The current level of copper and lead, - Their levels in the previous analysis, - When did the oil change for the last time, - Is there an increase in the rate of change in the concentration of these metals since the previous analysis, - What else could lead to copper and lead in the oil sample, - Are there any other indications of a problem? The increased content of copper and lead in the oil, indeed, can be caused by wear of the bearing inside the engine, however, other sources of these elements are possible. So copper is used in plain bearings, various bushings, radiators, as well as in antiwear additives. Lead is mainly used in bearings, but it can get into oil and from solder in radiators. In addition, leaching of a radiator or oil cooler can result in elevated levels of copper in the report. Also, before taking corrective actions, you should make sure that this abnormal sample is correctly labeled. For the greatest guarantee, another oil sample should be taken and analyzed. If the results are consistent, more research should be done to identify the root cause of the problem. For example, you can perform an infrared analysis of the refrigerant content in this case. Since it is leaking, it can also give increased values of copper and lead. You should also carefully look at the contents of other elements in the report. If this growth is caused by problems with the bearing, then the iron content should also be increased, which can be seen both in the results of spectral analysis and with a magnetometer. However, if the iron is normal, and an increased potassium result is detected, then this indicates the presence of a refrigerant in the oil. It should be remembered that when using oil analysis to diagnose equipment, the result of one test may not be enough - you should consider the trend. In this regard, the company LLC "Baltech" provides ready-made solutions (Minilab series Minilab) for the correct diagnosis of equipment for oil analysis, rather than individual devices. So the Minilab 23 minilab can be used to determine changes in the chemical state of the oil and its contamination with water and other liquids. It makes it possible to adjust the safe oil change intervals, as well as to determine the presence of leaks in the cooling system. Minilab 53 and Minilab 153 minilabs, in addition to the functions available in the previous minilab, allow the detection of contamination and wear particles. In addition, all Minilab series mini laboratories come with expert software with three-vector diagrams and color coding, which simplifies the interpretation of the data, and Baltech LLC itself offers specialist training in the basics of oil analysis and tribology. Training courses on the topics of NO-2010 "The concept of" Reliable equipment "(developer Romanov Roman Alexandrovich, 921-757-90-51) and" TOP-105 Fundamentals of the theory of lubrication of machines. Tribodiagnosis. The oil analysis method under operating conditions ”is carried out within five working days and lasting forty academic hours.
