Abstract:
One of the most important handicaps when using the oil analysis technique for predictive maintenance, is the processing of the results. The oil analysis technique allows obtaining relevant information about the state of the lubricant, the engine and other auxiliary elements. However, it is necessary, to process this information and to define the references with which the numerical results obtained must be compared.In the system considered the different analyses performed on the oil sample have been divided into three different types: oil properties, oil contaminants and engine wear elements. Consequently, each type of result is evaluated in a different way.Finally, the evaluation process of the different analyses allows the system to qualify each analysis with a numerical value which will be used in an expert system.
