I.Main features 1. The design of double-sided experiment platform can satisfy two groups of students at the same time. The components, circuits and electrical control of the two sides are independently controlled, and the experiment is not interfered with each other. 2. The modular structure design of structures, the experiment is simple, convenient, various pneumatic components into separate modules, with convenient installation plate, the experiment can freely on general aluminum plate, when assembling various experimental circuits, the operation is simple and convenient. 3. Quick and reliable connection, easy installation and convenient connection. 4. Standard industrial components, reliable edge and safety. 5. The laboratory has a computer communication interface which can be controlled with PLC programming device; 6. The gas source adopts the no-oil silent air compressor, which has the characteristics of low noise (< 55db). The gas is odorless and tasteless and clean and dry. 7. Multiple control methods: single pneumatic control circuit, electric control pneumatic circuit with relay, PLC control pneumatic circuit, etc. II.Training workbench 1. The experimental platform adopts double-sided structure, which effectively saves the laboratory land and has a high cost performance. 2. The laboratory bench is made of high quality steel frame and high quality cold rolled steel. The lower part of the platform has components and tool-storage cabinets. The actual training screen is specially designed for the special belt "T", which can be easily and freely installed with pneumatic components and connected with the experimental circuit.
