Teaching Methods of Hydraulic Components Based on Hydraulic-electrical Analogy

Abstract

In order to solve the problem that the hydraulic components are abstract and their functions are difficult to understand, the analogy teaching method of hydraulic components is introduced in this paper based on the functional similarity of the electrical components and hydraulic components. Firstly, the comparison of fundamental laws and concepts of electrical components and hydraulic components are introduced. Then the corresponding hydraulic components and electrical components, which have the similar function, are given respectively. Finally, the performance analysis methods of cone valve and spool valve based on the bridge network theory are introduced and the performance of spool valve is given.
