I. Overview

The hydraulic and pneumatic transmission integrated training device features a "two-in-one" structure, equipped with two sets of experimental equipment. One set is an pneumatic and PLC training platform, and the other is a hydraulic transmission and PLC training platform, each with its own independent PLC electrical control system.

The same unit can independently perform hydraulic control, pneumatic control, and corresponding basic circuits and application experiments. It can also be used for PLC programming and application control experiments, suitable for teaching and training in courses such as "Hydraulic Transmission and Control," "Hydraulic and Pneumatic Transmission," and "Pneumatic Technology."

Section II: Technical Parameters and Specifications of Hydraulic Transmission

Integrating genuine hydraulic components, various execution modules, relay control units, and PLC programming control technology, the hydraulic components are designed as independent modules, each equipped with a base plate featuring elastic pins. During practical training, these can be assembled into various hydraulic system circuits on standard aluminum profiles. The motor and pump are connected bearing-style (integrated) and then fixed to the oil tank; the oil tank and control panel are placed separately. The system features three-phase leakage protection, DC power with overcurrent protection, a rated pressure of 6.3 Mpa, and automatically unloads when pressure is too high.
