QD-B double-sided pneumatic experimental platform

Fashionable profile design

Regular sheet metal models

Compared to QD-A type, QD-B type equipment adopts a double-sided structure on the workbench: that is, one experimental workbench is equipped with two sets of pneumatic components, sharing a working pump source. In this way, a workbench can allow two groups of students to conduct independent experiments simultaneously, fully utilizing existing experimental equipment and achieving resource sharing! Fully equipped with the functions required for QD-A devices. Its performance price ratio has increased by nearly twice! The specific structural and performance characteristics are introduced as follows:
Similarly, the QD-B pneumatic PLC control comprehensive teaching experimental device meets the requirements of modern pneumatic professional teaching experiments. Designed based on general textbooks such as Hydraulic and Pneumatic Transmission and Pneumatic Control Technology. In addition to conducting conventional pneumatic basic control circuit experiments, this system can also conduct simulated pneumatic control technology application experiments, pneumatic technology course design, etc.
The experimental equipment adopts PLC control mode. Using PLC control system to connect with computer, from learning simple PLC instruction programming and ladder diagram programming, to delving into the application of PLC control, communication with computer, online debugging and other experimental functions. It is the perfect combination of pneumatic technology and electrical PLC control technology.
