DLYY-GZFX01 Hydraulic Fault Analysis Training System of vocational education equipment 

Equipment Overview

This DLYY-GZFX01 Hydraulic Fault Analysis Training System of vocational education equipment takes the injection molding machine hydraulic system commonly used in typical industrial sites as the training object, and trains students to be familiar with and understand the working principles and basic concepts of Hydraulic Fault Analysis ,hydraulic transmission, the composition characteristics and applications of components, and the composition of the injection molding machine hydraulic system. Preliminary mastery of hydraulic system debugging, handling and troubleshooting of common hydraulic system faults. At the same time, the device is also equipped with an intelligent man-machine operation assessment system. The teacher can set up the fault through the host computer or the intelligent man-machine operating system. The students analyze the fault phenomenon and the specific circuit, and finally perform the fault through the intelligent man-machine exchange system Elimination to improve the comprehensive ability of students. It is suitable for the practical training and teaching of "hydraulic transmission", "hydraulic and pneumatic transmission" courses of electromechanical majors in various vocational colleges.
