MONITORAMENTO E AVALIAÇÃO DA CONDIÇÃO DO SISTEMA HIDRÁULICO DE ESCAVADEIRAS ATRAVÉS DA ANÁLISE DE ÓLEO

Abstract

This work aims to present, analyze and evaluate the results of the analysis of the conditions of hydraulic oils subjected to contaminants from their deterioration, as well as the condition of their mobile components in order to preserve the useful life, the reliability of the equipment and monitor the trend deterioration of hydraulic excavator oils. The analytical study of the oil contributes to the preservation of such components, knowing how it is chemically giving the opportunity to carry out a planned corrective maintenance in its replacement, in case the oil presents conditions that make it lose its characteristics. Two hydraulic excavators of the same brand and model were chosen, being the Hyundai brand and model R210LC-7, owned by the company Pavican Paveamento e Terraplenagem. The used oil samples were taken from the hydraulic reservoirs of the excavators in the field by a maintenance technician, for the new oil sample was taken directly from the Lubrax drum. In partnership with Proluminas Lubrificantes, it was possible to carry out the analysis of the samples collected from the excavators. The objectives were achieved, it is possible to observe the tendency of deterioration, as well as the absolute number of particles in the oil, making a study on the preventive maintenance applied to the equipment with the predictive maintenance of the oil analysis.
