. System features
1. The integrity of the wind system: It is completely consistent with the actual ventilation system, control function, protection function, and display function.
2. The system is the same as the real ventilation and smoke exhaust system, and the wind system processing system principle is the same. The miniaturization shows the characteristics, structure, and control method of the ventilation and smoke exhaust system.
3. The device intuitively shows the system structure and working principle of the ventilation system, which is convenient for teachers to demonstrate and expl*n and for students to understand and master the textbook knowledge. Reasonable structure and beautiful shape The device has a reasonable and compact structure and beautiful shape. The tr*ning table is also equipped with four universal wheels and four fixed adjustment mechanisms for easy movement and fixation.
4. Improving students' analytical ability through specific phenomena is conducive to students applying theory to practice and cultivating their practical hands-on ability.
5. It is equipped with a current-type leakage protection device. When the ground leakage current exceeds a cert*n value, it trips and cuts off the power supply; and there is a thermal protection device to protect the compressor from overheating and overload.
6. 2 DDC digital control modules, 16 AI inputs, 6 DO inputs, and 8 DO
outputs 4. System Configuration
1. The system consists of a simulated room equipment system and a smoke exhaust fan system (m*nly composed of *r vents, *r valves, smoke exhaust windows and smoke exhaust fans, smoke exhaust fire dampers, *r supply fans, *r supply ducts and smoke exhaust ducts and related fire detectors, and linkage control systems
2. Simulation of smoke exhaust system control: The fire smoke exhaust system consists of fans, *r ducts, automatic smoke exhaust valves, fire dampers, connection control cabinets and linkage control centers. The working principle of the fire smoke exhaust system is that when the fire control center receives a fire signal, the linkage fire smoke exhaust fan control cabinet starts the fan and opens the smoke exhaust valve to discharge the indoor smoke from the *r duct to the outside to achieve the smoke exhaust effect.
3. The pressurized *r supply fan adopts a multi-wing centrifugal fan.
4. The pressurized *r supply pipeline is made of non-combustible materials, and the pressurized *r supply vents and are normally closed, and are controlled manually or electrically.
5. The 70-degree smoke exhaust fire protection is made of control actuators and non-combustible materials.
6. The smoke exhaust fan adopts an axial flow fan, which can be operated at 280 degrees for not less than 30 minutes.
7. Smoke exhaust fire damper. Installed on the pipe of mechanical smoke exhaust facilities, usually open, closed when the temperature in the exhaust pipe reaches 280 degrees in a fire.
8. Smoke exhaust port, installed on the mechanical smoke exhaust duct as the smoke inlet, usually closed. Open manually or electrically when smoke exhaust is required in a fire
