Research On Oil Analyses Of Mining Diesel Engine Oil

By utilizing various kinds of fluid analyze technology and through the live following experiment to 108 tons of dump trucks engine used in Huo LinHe open-air coal industry Limited Company, this text makes a more complete engine oil-changing standard depending on the condition which is suitable for the operating mode requirements of this kind of equipments and launches the trouble diagnose system of the engine oil liquid analyze.The research to wearing and tearing law of the engine has been carried on through the live following experiment. The wearing and tearing law of the engine has been obtained and the oil changing cycle of lubricating oil has been confirmed. The wearing and tearing mechanism of the engine has been studied. The wear and tear element density and early warning value of the gradient have been discussed and made. Through AIC criterion of time series analysis it judges whether the wearing and tearing state of the machine has changed, the gray theory has been utilized to predict the future state of the system.
