1. Product Overview
Gas boiler hot water heating circulation system comprehensive tr*ning device "Digital control module is the control core, and the upper computer configuration software is used as the monitoring interface to display the working status and operating parameters in real time. The system is m*nly composed of three basic parts: electric hot water boiler, heating pipe and heat sink, and is equipped with expansion tank, circulating water pump, heat meter, self-operated pressure difference control valve, electric flow control valve, solenoid valve, automatic exhaust valve, temperature acquisition module, pressure acquisition module, flow acquisition module and other auxiliary equipment, which can form three different system forms: single-tube downstream type, single-tube leap type and double-tube upper supply and lower return type. It is suitable for teaching and tr*ning of related courses such as *r conditioning engineering, heating and ventilation and construction
majors in higher vocational colleges and vocational schools. 2. Technical performance

2. Working environment: temperature -10℃ ~ +40℃; relative humidity <85% (25℃) altitude <4000m
3. Device capacity: <2kVA
4. Equipped with voltage type leakage protection, current type leakage protection, and grounding protection, safety meets relevant national standards.
5. Gas, liquefied gas
III. System configuration
1. Tr*ning table
The tr*ning table adopts a st*nless steel splicing structure, and the entire heating system is arranged on a mesh plate.
2. Hot water heating system
The system consists of gas hot water boilers, heating pipes, heat sinks, expansion tanks, circulating water pumps, heat meters, self-operated differential pressure control valves, electric flow control valves, solenoid valves, turbine flow sensors , pressure transmitters, temperature sensors, and automatic exhaust valves.
3. Single chip microcomputer , PLC programmable design and control virtual simulation software:
This software is developed based on unity3d, with built-in experimental steps, experimental instructions, circuit diagrams, component lists, connection lines, power on, circuit diagrams, scene reset, return and other buttons. After the connection and code are correct, the three-dimensional machine tool model can be operated through the start/stop, forward motion, and reverse motion buttons. When the line is connected, the three-dimensional machine tool model can be enlarged/reduced and translated.
1. Relay control: Read the experimental instructions and enter the experiment. By reading the circuit diagram, select relays, thermal relays, switches and other components in the component list and drag and drop them into the electrical cabinet. The limiter is placed on the three-dimensional machine tool model. You can choose to cover the cover. Some component names can be renamed. Then click the connect line button to connect the terminals. After the machine tool circuit is successfully connected, choose to turn on the power and operate. If the component or line connection is wrong, an error box will pop up. The scene can be reset at any time.
2. PLC control: The experiment is the same as relay control, and the PLC control function is added. After the connection is completed, enter the program writing interface through the PLC coding button. Write two forward and reverse programs. There are 12 ladder diagram symbols in total. After writing, select Submit for program verification. After successful verification, turn on the power to operate. If there are component, line connection, and code errors, an error box will pop up. The scene can be reset at any time.
3. Single chip microcomputer control: The experiment is the same as the relay control, with the single chip microcomputer control function added. After the connection is completed, enter the programming interface through the C coding button, enter the correct C language code, submit the verification successfully, turn on the power to operate, and the error box will pop up for components, line connections, and code errors. The scene can be reset at any time.
