Abstract

To apply magnetic fluid in the hydraulic transmission medium, it is necessary to study the influence of magnetic fluid medium on the temperature rise characteristics of hydraulic system. Hydraulic oil based magnetic fluid was prepared by a two-step method. While the viscosity characteristics of prepared magnetic fluid with different concentrations were tested, the temperature rise characteristic of the 0-90min hydraulic circuit was also examined and analyzed. The results show that the temperature of the magnetic fluid hydraulic medium rises fast at first, then the rising rate slows down which will rise dramatically again after passing a certain point. Under the same conditions, the higher the magnetic fluid concentration, the greater the heat of the hydraulic system. It is considered that high temperature rise is the main problem in the development of magnetic fluid as hydraulic medium. The mechanism of heating should be further studied and the preparation technology should be improved.
