WEAR INVESTIGATION OF ECOLOGICALELECTRORHEOLOGICAL FLUID

The article studies the wear an ecological electrorheological fluid caused by the occurrence of electricalbreakdowns. The fluid studied– eER1–is composed of organic solid particles, vegetable oil, and water, whichis included to enhance its electrical properties. A special device was built for the destruction of the eER1 fluid.The study involves the preparation (using several measuring devices of different designs) and comparison ofthe rheological characteristics performed for valve and shear flow, for both unused and used eER1 fluid. Basedon the analysis of the study results, the causes and extent of wear in the tested ecological electrorheologicalfluid were identified, and general conclusions were drawn.
