DLQD-DP301 Advanced Proportional pneumatic Training System Authorized by Worlddidac Association

Equipment Overview

1.Proportional pneumatic trainer Convenient experiment: The pneumatic workbench is equipped with four casters for easy movement and installation. Since the angle and height of the panel are designed according to ergonomics, it can be conveniently used in experiments. The groove interval of the panel is 25mm, and various components can be plugged and unplugged easily.

2. Good flexibility: Each pneumatic component is an independent module, and each is equipped with a bottom plate with elastic pins. Various pneumatic circuits can be constructed on general aluminum profiles during training. The installation is fast, the layout is flexible, and the pneumatic circuits are clear and clear.

3. Low noise: using a silent air compressor, low operating noise, providing a better training environment for the training room.

4. Strong practicability: The pneumatic circuit adopts quick connectors, which is convenient for students to quickly build the pneumatic circuit. The electric control circuit adopts a special training connection wire with protective function. Students can design a pneumatic application system by themselves, which can exercise their ability to combine theory with practice and have strong training.

5. The electrical control unit adopts an independent relay control unit and multiple button units for electrical control, which is simple and clear. In addition, the device is also equipped with PLC programmable controllers, which can deepen students' understanding and mastery of PLC programmable controllers. PLC programmable controller can communicate with PC microcomputer to realize microcomputer intelligent control. It is also possible to form a separate control method combining PLC and traditional relay control, which strengthens students' understanding of control theory.

6. Diversification of electrical proportional valves: Electrical proportional valves can be divided into pressure-type electrical proportional valves and flow-type electrical proportional valves according to different control parameters. The former is the proportional change of output pressure with the change of the input electrical signal (current or voltage), and the latter is the proportional change of the output flow with the change of the input electrical signal.

7. Good safety: with current-type leakage protection, when the leakage to the ground exceeds 30mA, the power supply will be cut off; the electrical control adopts DC 24V power supply with overcurrent protection to prevent damage to the equipment due to misoperation; the rated pressure of the system is 0.6MPa.
