DLYY-DH301 Proportional Hydraulic Training System vocational education equipment 

Equipment Overview

This DLYY-DH301 Proportional Hydraulic Training System vocational education equipment  is equipped with a variety of hydraulic control valves, hydraulic cylinders, hydraulic motors and other hydraulic components and related tools. Learn theoretical knowledge and observe the appearance characteristics of hydraulic components through the instructions to deepen students’ understanding of the structure and working principles of hydraulic components. Install and debug the entire hydraulic transmission system on this basis. The training system uses an open structure operating panel. Various hydraulic components can be flexibly installed on the operating panel. The components are connected by hydraulic hoses. The quick-change joints of the hydraulic hoses can make the training experiment fast and safe. In addition to the conventional hydraulic basic control loop experiments, the system can also carry out hydraulic control technology application experiments, hydraulic technology course design, and basic application experiments. It is a typical experimental equipment with a perfect combination of electromechanics.
