  • DLPCS-YL02 Pressure Control Trainer of vocational education equipment

    The trainer provided a comprehensive experiment, introduced the basic principles of control engineering, and used pressure control examples. The air pressure control system is a second order system. It includes an in-line pressure vessel connected by a flow control valve. An additional valve on the other tank allows air to be used as much as possible to simulate a disturbance variable. The pressure sensor measures the pressure of the two ships. The controller used is the most advanced digital industrial controller in a country. The actuator in the loop is the standard current signal input of the pneumatic control valve. The control variable X and the manipulated variable y are directly drawn on the integrated dual-channel line recorder. In addition, the variable can be tapped as an analog signal in the laboratory jack of the switch cabinet. This enables external recording equipment such as an oscilloscope or flat-panel plotter.

  • DLPCS-WD02 Temperature Control Trainer of DLGK-YL101 Pressure Process Control Trainer of vocational education equipment

    The trainer provides a comprehensive experimental introduction to the basic principles of control engineering, using temperature control examples. A circulating pump provides water in a closed circuit. The flow of water can be adjusted by a manual valve. The circuit also includes a heater, a heat exchanger fan, and three integrated thermocouple temperature measurement. Dead time can indicate the use of different lengths of process delay. Use thyristor power controller actuator. The controller used is the most advanced digital industrial controller in a country. It can be used as a continuous or a switching device, and the heater can be activated by actuators and/or fans. The control variable X and the manipulated variable y are directly drawn on the integrated dual-channel line recorder. In addition, the variable can be tapped as an analog signal in the laboratory jack of the switch cabinet. This enables external recording equipment such as an oscilloscope or flat-panel plotter.

  • DLPCS-SW02 Liquid Level Control Training System

    The trainer used a control example to introduce a comprehensive experimental basis for the basic principles of control engineering. A pump loads water from a storage tank into a transparent liquid level control tank, and a pressure sensor is installed at the bottom of the liquid level control tank. The controller used is the most advanced digital industrial controller in a country. The actuators in the control loop are pneumatic control valves and electro-pneumatic positioners. A ball valve in the outlet allows the defined disturbance variable to be generated. The control variable X and the manipulated variable y are directly drawn on the integrated two-channel line machine. In addition, the variable can be used in the analog signal of the jack in the switch cabinet room. Such as oscilloscope or flat plotter.

    1) Composition and structure characteristics 1. Simple structure: the overall structure has a skeleton and an executive part of the control cabinet, 2. Convenient operation, all operation, display and execution components are installed with external leakage, which is convenient for observation and operation 3. The overall frame is made of stainless steel to prevent the equipment from rusting 4. Only single-phase three-wire AC power supply can be put into use, and the floor space is small, saving housing and reducing infrastructure investment 5. The structure design of the open experimental object makes the experimental object intuitive and easy to understand. 6. The design of the hardware object fully considers the certainty of its mathematical model, which is consistent with theoretical textbooks. 7. The parameters and characteristics of the selected instruments meet the design requirements of the system, and the experimental results are ideal. 8. The disassembly and assembly of instruments and meters deepens students' understanding of engineering instruments and meters, especially the internal principles of devices. 9. A variety of control signals, a variety of control signals and control methods can be selected according to the experimental project 10. You can do DIY experiments; the training device can change the experimental objects and connection methods according to user requirements 11. Human-computer interactive experiment. The configuration software is used for interactive operation, that is, what you see is what you get, and data can also be collected. 2) Security protection 1. The power supply has protections such as leakage, overvoltage, overcurrent, and short circuit, which protect the safety of trainers. 2. Separation of water and electricity; that is, the control system and the execution system are separated, and all the wiring of the execution system is treated with waterproof measures 3) Configure teaching software
