Experimental Research for Measuring Friction Forces from Rod Sealing at the Hydraulic Cylinders

Abstract

The paper presents experimental equipment and research results conducted by Hydraulics and Pneumatics Research Institute INOE 2000-IHP Romania in cooperation with Institute PPRIME – University of Poitiers France, in order to determine the friction forces that occur in mobile rod sealing at hydraulic cylinders. In the first part the device and the experimental stand are presented and in the second part, some obtained results are shown. The graphics illustrate the evolution of the friction forces at the rod seal of the hydraulic cylinders. Experimental research marks the beginning of a major action on the tribological behaviour of hydraulic seals, which will be developed in the next period
