QD-B Type Double-Sided Pneumatic Test Bench

QD-B Type Double-Sided Pneumatic Test Bench

Compared to the QD-A model, the workbench of the QD-B model features a dual-sided design: a single experimental workbench is equipped with two sets of pneumatic components, sharing a single work pump source. This allows two groups of students to conduct independent experiments simultaneously on a single workbench, fully utilizing the existing experimental equipment and achieving resource sharing! It is fully equipped with all the functions of the QD-A model. Its performance-to-price ratio is nearly doubled! The specific structural and performance features are as follows:

Similarly, the QD-B type pneumatic PLC control integrated teaching and experimental set is designed to meet the requirements of modern pneumatic professional teaching and experiments. Based on the contents of general textbooks such as "Hydraulic and Pneumatic Transmission" and "Pneumatic Control Technology," this system is designed. In addition to conducting conventional pneumatic basic control circuit experiments, it can also perform simulation experiments on the application of pneumatic control technology and pneumatic technology course design.

The experimental equipment adopts PLC control. It connects the PLC control system with a computer, enabling experiments from basic PLC instruction programming to ladder diagram programming, and further into the application of PLC control, including communication with computers and online debugging functions. It is a perfect integration of pneumatic technology and electrical PLC control technology.
