Programación de los intervalos de lubricación de la flota vehicular de volquetas del GAD Municipal de Guano mediante análisis tribológico

Abstract

In the municipal GAD of Guano canton, it is plausible that the lack of equipment makes the maintenance carried out empirically, ignoring the benefit of carrying out a tribological analysis of the lubricant in different stages of operation to identify the correct lubricant and proposing an optimized replacement program. Therefore, the objective of the present investigation was to elaborate a plan of lubrication intervals of the engines of the vehicle fleet of dump trucks of the municipal GAD of the Guano canton through tribological analysis. The implemented methodology had a quantitative approach, considering the numerical measurement; it also presents a modality of study of the documentary and field type, given that the collection of samples from the dump trucks was carried out in the municipal GAD of Guano. The six dump trucks that are in an operational state were considered strategic points for their respective oil analysis using different methods, techniques, and instruments. The analysis tribology for this study consists of five teams that helped to measure various parameters in which the lubricating oil is operating, such as a density meter, FluidScan, Oil View Quick-Check, centrifugal viscometer, pyrometer. The analysis of the different equipment shows the wear of the additive, the increase of sulfates, soot, oxidation, and decrease in TBN, plus an analysis with wear alarms regarding chemical severity and ferrous damage, the decrease in viscosity in the starting and operating state of the oil to 40°C and 100°C. It is concluded that the lubricating oil works as a unit, that while it affects specific operational parameters, this will significantly affect other properties of this. In addition, the new lubrication plan is applied to the characteristics and properties of the lubricant during an oil change.
