Analysis of Hydraulic Oil in Handling Lines Baljer & Zembrod Using the Methods of Tribotechnical Diagnostics

Abstract:

This article describes an experiment aimed at monitoring of the oil condition and machine wear mode used in hydraulic system of handling line Baljer & Zembrod by Tribotechnical diagnostics methods. The experiment lasted for one year, five oil sample were taken during this period and evaluated their qualitative properties. By oil analysis were evaluated the physical-chemical analysis: viscosity at 40 °C, water content and Total Acid Number. This oil analysis further includes FTIR analysis for monitoring of degradation products in oil; monitoring of oil contamination for determine the level of contamination and number of wear particles using with laser particle analyser and atomic emission spectroscopy for elemental analysis. Increased of oil contamination and increased content of wear metals as iron, chromium and copper were detected only in the 5th oil sample. Other monitored parameters were situated within the required tolerance at all time of the experiment. Based on the results of the oil analysis and for increased of thermal oxidative degradation products of the oil detected by FTIR analysis we recommend that the oil should be cleaning using with electrostatic filters when hydraulic oil will be exchanged.
