The use of biobased
hydraulic oils becomes more popular in the different industries,
but especially in agriculture machinery. This is stimulated by the fact that significant amount of
hydraulic oils effluence in the environment and therefore leaves a negative impact to the
e
cosystem. Besides of that, the part of sold hydraulic oils grows and now forms approximately
15%
of total oil consumption amounts worldwide (Nagendramma & Kaul, 2012)
.
The aim of this research was to study
the compatibility of the comercially produced mine
ral and
biobased hydraulic oils, identify viscosity of a different mixtures in the entire work temperature
range, as also changes of anti
-
frictional properties. Two different oils and three mixtures were
tested. Special hydraulic experimental apparatus was
established for visual observation of fluid
properties. Sliding friction bench was used for the comparision of friction properties.
The results showed that change of the working pressure and temperature of the hydraulic oil in
the various mixtures of mine
ral and biological hydraulic oils do not change its original
appearance. It was observed that the highest viscosity
