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.

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.

The DLLY-HYGS462 constant pressure water supply training system is composed of six-story residential fire protection system and domestic water supply system. The fire protection and water supply pipelines are independent, which integrates safety and water supply. The system includes four pump motors: two of them provide normal daily water supply during the day, one is a dormant pump, and the other is a fire pump to provide fire water. The device also uses PLC, frequency converter, pressure transmitter, pressure relay instrument, one-way control valve, reservoir, water supply buffer device, which can complete the floor constant pressure water supply training in multiple modes, and is used for teaching and research. Pressure water supply technology provides an open operating platform.
