Abstract:
Briefly, there are described problems of the use of biodegradable working liquids. There is a description of the test of the biodegradable hydraulic oil of the plant origin PRIMOL EKO 36H in high pressure hydraulic aggregate. Introduced there were the overall results of selected analyses carried out with the goal to judge the eligibility of the selected diagnostically signals for the evaluation of the changes of the technical condition of the used hydraulic oil.
