The process hybrid training system can be used to create complex PLC control functions in the field of process engineering, especially the process involving metering and mixing. The basic structure of the system, including storage tanks, centrifugal pumps and a demonstration panel, all components are clear. The pump delivers water to the three water tanks, which are controlled by solenoid valves. The sensitivity of the water level monitoring capacitor proximity switch in the three water tanks is adjustable. The fluids from the three tanks can be mixed in the downstream mixing tank. The mixing tank is also equipped with three proximity switches. A mixing machine that helps the mixing process. All tanks are transparent, so the conveying and mixing process is clearly visible.

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.

The DLPCS-WDMK module panel of the control system is ready to install components. In combination with other modular control components, it enables the temperature control system to have different characteristics for construction and research.

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.

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.

This equipment takes flow control as an example to give a comprehensive experimental introduction to the basic principles of control engineering. All components are clearly placed on the vertical front panel. The large-format process diagram is helpful for understanding. The water pump transports the water in the storage tank to the pipe section. The flow rate is measured by the paddle wheel sensor. The transparent float flowmeter enables the control process to be clearly observed. The controller used is the most advanced digital industrial controller. The actuator in the control loop is an electric control valve. The ball valve in the pipeline section allows defined disturbance variables to be generated. The control variable x and the manipulated variable y can be used as analog signals for laboratory jacks. This allows external recording equipment such as plotters or oscilloscopes to be connected.
