Research on the feature of hydraulic oil of electro-hydraulic pump

The full paper begins with the importance of electro-hydraulic pump which is a highly integrated combination of electric motor and hydraulic pump. The development of electro-hydraulic pump, which integrates interdisciplinary theories, in our opinions, does study on all kinds of performances. We now present our finite element model on flow and temperature field of the fluid which we believe can much facilitate the research. In the paper, the said model was explained in some details; in this abstract, we just add some associated remarks to naming the topics, such as the momentum equations, energy equation and mass equation. Finally we utilize ANSYS software to perform computer simulation and the results are shown in the full paper. These results show the performance on velocity and temperature of the electro-hydraulic pump, and the future direction of design.
