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.

Filtration Systems Design for Universal Oils in Agricultural Tractors

“…The suggested oil change period is conservative and results in a non-efficient usage of oil. [11] and [12] confirm this fact presenting the results of hydraulic oil analysis, which mention exceeded contamination limits, but physical and chemical properties, namely kinematic viscosity at 40 °C, total acid number and water content was situated within the required tolerance during all the time of operation. The additional filtration system can eliminate the oil contamination to protect the machine against excessive wear and provides the efficient usage of oil.…”

“…The results of Hnilicová et al [11] show that water content considerably affects the most of oil properties. In case of all three tractors, the non-measurable value of water content (Table 1, 2 and 3) is typical for most tractors because the transmission and hydraulic system is well protected against the water from the environment, and liquefied water from ambient air represents only a negligible volume regarding the high volume oil fill.…”

Analysis of Degradation of Motor Oils Used in ZETOR Tractors

“…However, these procedures are time consuming and require relevant laboratory apparatus. Therefore, when evaluating the current lubricant state and its residual durability, we use instrumentation methods, such as Fourier Transform Infrared Spectrometry (FTIR Spectrometry) (Glos and Svoboda, 2015;Hnilicová et al, 2016;Král et al, 2014;Sejkorová et al, 2014) combined with chemometric software (Al-Ghouti et al, 2010;Caneca et al, 2006;Sejkorová, 2013;Van de Voort et al, 2006), electro-chemical methods (Tomášková et al, 2014), emission and absorption spectrometry (Glos and Sejkorová, 2012;Mihalčová, 2014;Kumbár et al, 2014), a particle analysis using particle counters (Juránek et al, 2011;Kučera et al, 2016), and ferrography (Mihalčová and Rimár, 2015;Machalíková et al, 2008;Roylance, 2005).…”
