Investigation of degradation of ecological hydraulic fluid

Popis výsledku v původním jazyce

This article deals on the impact of the ecological hydraulic fluid type hydraulic environmental ester synthetic oil on operation of mini excavator hydraulic circuit. An operational test was to 500 engine hours. Hydraulic fluid is evaluated for chemical contamination. Fluid samples were taken from the mini excavator at 250 engine hours intervals. These samples were subjected to IR spectroscopic analysis, kinematic viscosity measurements at 40 degrees C and 100 degrees C, total acid number measurement and differential scanning calorimetry. It was found that the ecological hydraulic oil does not influence the operation of the mini excavator. Based on the achieved results, it was shown that the degradation processes during the operational test of the ecological fluid do not affect the operating parameters of the monitored machine. The presented paper also presents the results of the influence of hydraulic on the flow characteristics of the hydraulic pump.
