Aplicabilidade de análise de fluidos como manutenção preditiva em maquinário agrícola com estudo de casos visando economia em manutenção corretiva.

Abstract

The lubricating oil check identifies and counts the number of metal particles and external contamination present in the oil, thus allowing not only quantify the wear but also indicates the probably worn part through the particle count of alloying elements. Were checked five samples, withdrawals every 250 worked hours, from a John Deere tractor model 5075EF until his state was critical and six samples, withdrawals every 250 worked hours, from a John Deere harvest machine model 3520 until his state was critical. The difference between sample’s quantity is because tractor need intervention before harvest machine. After the compartment’s inspection and maintenance achievement were made a comparison between maintenance cost using fluid analysis and corrective maintenance. The analyses, associated with the inspection of the compartment, provide applicability for the technique, fluid analisys, in agricultural machines, showing up as economical to a farmer.
