Variable air volume ventilation and smoke exhaust training device

The variable --r volume ventilation and smoke discharge tr--ning system According to its tobacco prevention and smoke and exhaust system, it is divided into a smoke control system and a smoke -proof system. The equipment is designed as a mechanical pressure supply --r supply system and mechanical smoke exhaust system.

Variable --r volume ventilation and smoke exhaust tr--ning system consists of an analog room equipment and smoke exhaust fan system (m--nly consolidated by --r outlets, wind valves, smoke discharge windows and smoke exhaust fan, fire firewood valve, --r supply fan, --r supply --rway, smoke exhaust, and smoke exhaust. The --r ducts and related fire detectors and linkage control systems form a full system intelligent operation, and the energy -saving technology control of frequency conversion technology controls the energy conservation control requirements through various system components of the frequency conversion technology control system.

2. Technical parameters

1. Enter power supply: single -phase three -line ～ 380V ± 10% 50Hz 50Hz

2. Working environment: The environmental temperature range is -5 ° C ~+40 ° C relative humidity <85%(25 ° C) altitude <4000m

3. Device capacity: <3.8kva

4, shape size: 3000mm × 1000mm × 1600mm

5. Safety protection: It has leakage voltage and leakage current protection device, and safely meets national standards

6. Working environment: The environmental temperature range is -5 ℃ ～+40 ℃ The relative humidity is <85%(25 ℃) altitude <4000m

Third, systemic characteristics

1. The integrity of the wind system, the system and the real subway --r -conditioning system, and the wind system processing system is the same, and the miniaturization shows the characteristics, structure, and control methods of the subway --r -conditioning system.

1. The composition and characteristics of the comprehensive tr--ning device system of heat transfer process

Equipment m--n body: Object part: length × width × height: 3700 × 2000 × 3500mm. The whole machine uses steel installation framework (two layers of design, one layer of plane is convenient to operate, rep--r, enter and exit. Guardr--l, non -slip pattern)

1. The system's heat exchange system is: water vapor---r (dual-column tube heat exchanges); cold --r-heat --r (sleeve, column tube, plate type); water-hot --r system (￠ 159 single tube heat exchange device) Essence

2. Taking the heating device of 9 159 as the m--n body to do heat transfer tr--ning, the dual -parallel tube heat exchanger structure can be operated normally, one is a fault operation, compared with each other, and the dual -parallel tube is replaced. The heat shift can also be performed by the heat exchanger. The steam pressure and flow adjustment system of the system are required to be controlled in the shell of the system. At the same time, the system can automatically set the fault point, and the ability to tr--n students (gas blockage, water blocking).

3. Make a tube heat exchangeer into dissectionable formula. If it is not installed on the system, the teacher will expl--n the structure of the student to the student, so that students will strengthen their understanding of the structure of the heat exchanger.

4. The temperature is measured by high -precision imported patch type exquisite PT100+intelligent inspection recorder measurement. Each temperature zone is sent to the local number, the traffic detection band is delivered on the spot, and the basic principles and processes of the computer for data collection and process control. The steam source adopts industrial standard automatic steam generator. The heating pipeline adopts a pipeline flange connection, which is not only good -sealing performance, but also easy to disassemble. Display the detection control instrument on the spot: select Xiamen Yudian smart instrument (with local control RS485 communication interface).

5. Local intelligent instrumentation electrical console: Steel spraying plastic internal leakage protection --r switch, current -type leakage protector to fully consider personal safety protection; at the same time, each set of strong electricity output has knob switch control; Lights, switching power supply, contactor, solid -state relay, self -lock switch, plastic copper wire, rubber sleeve, shielding wire, aluminum alloy wire groove, etc.
