EXPERIMENTAL ANALYSIS OF THE RHEOLOGICAL PROPERTIES OF HYDRAULIC OILS

Andreea-Mirela TELEASA, Alexandru Valentin RADULESCU

Abstract


In this paper, the rheological behavior of mineral hydraulic oil H46 and of the two biodegradable hydraulic oils HETG46 and HF-E46 is presented. The oils were tested from a rheological perspective using both the Newtonian model and the power law. From a thermal perspective, the oils were tested using the Reynolds model. Oil testing was carried out on the BROOKFIELD CAP 2000+ viscometer, which is controlled by CAPCALC 32 software through which the numerical data processing was carried out, as well as the general setting of the working parameters of the viscometer. The aim of the paper is to observe which of the hydraulic oils show good rheological behavior and subsequently can be used in hydraulic power plants.
