Programación de los intervalos de lubricación de la flota de maquinaria pesada del GAD Municipal de Guano mediante análisis tribológico

Abstract

The objective of this research project was to evaluate the oils used in heavy machinery to program the lubrication intervals of GAD Municipal de GUANO, applying tribological analysis of the degradation of engine oil, the attenuation of the oil in each of the engines was evaluated with a comparison of the properties found in each sample studied. The samples taken were planned through a schedule according to the availability of the operators, then they were analyzed with each of the equipment available in the tribology laboratory at Mechanics School. Once the results were obtained, the data was exported to an Excel template for a detailed treatment. Concluding that, due to the work hours, each machinery is subjected to different efforts and depending on the state of the engine each analyzed machinery will have different results. It was considered 5 machineries where it was possible to evidence that the backhoe loader has a considerable criticality compared to the other machineries, where only the motor grader and the excavator are in considerable conditions to work. These events occurred due to poor maintenance of the heavy machinery, which is not performed at the appropriate intervals, thus producing a considerable decrease in TBN, an increase in soot, oxidation, and the mixing of coolant with the oil. On the other hand, when these analyses were completed, it was possible to program the intervals either by cutting back or extending the working hours for their respective change.
