46. The pipeline system of the high-pressure fine water mist fire suppression system uses stainless steel pipes (304) with rust resistance, as once rust occurs, the rust deposits in the pipeline can block the nozzles, leading to system failure. The cleanliness of the pipeline system is crucial for the high-pressure fine water mist fire suppression system; therefore, after the pipeline installation, it must be strictly flushed, pressure tested, and purged. All pipes are焊接 using the TIG welding method.

47. High-pressure fine mist pump set (water supply unit) system composition: consists of fine mist nozzles (open, closed), filters, zone control valve sets (boxes), water tanks, and stainless steel pipelines, etc.

48. High-pressure fine mist pressure switch:

Loosen the top screw of the pressure switch and remove the cover.

2. Connect one of the cable wires to the common terminal.

3. Connect the other cable wire to the normally open contact.

4. After wiring is complete, securely close the cover and tighten the screws to restore the original state.

49. High-pressure fine mist open system working principle: In the standby condition, the fine mist system maintains a certain pressure from the pump group outlet to the pipeline before the zone control valve box. When the pressure drops below the 1MPa set start-up pressure of the pressure maintenance pump, the pump starts up to maintain a stable pressure (1-1.2 MPa) for the system pipeline.

50. High-pressure fine mist open system working principle: Upon detection of a fire signal by the detector, the fire alarm control master transmits the signal to the electric ball valve within the pump control cabinet and the electric ball valve in the zone control valve box. The high-pressure plunger pump automatically starts, and the electric ball valve in the zone control valve box opens, allowing high-pressure water to flow through pipes and nozzles to form a mist for extinguishing the fire.

51. High-pressure fine mist open system working principle: The pressure switch feedback system in the zone control valve box sends out a discharge signal, upon which the main unit receives the feedback signal and联动ly activates the spray indicator light.

52. High-pressure fine mist closed-loop system working principle: In the standby condition, the fine mist system maintains a certain pressure within the pipeline from the pump group outlet to the control valve box. When the pipeline pressure drops and falls below the set start-up pressure of the pressure maintenance pump by 1Mpa, the pressure maintenance pump activates to keep the system pipeline at a stable pressure of (1-1.2) MPa.

53. High-pressure fine mist closed-loop system working principle: Upon detection of a fire signal by the detector, the fire alarm control main unit transmits the signal to the pump group control cabinet. The high-pressure plunger pump starts up, and the electric ball valves in the zone control valve box are opened. The entire pipeline is filled with high-pressure water. Once the glass ball in the closed spray head reaches the activation temperature, it shatters, and the high-pressure water forms a mist through the nozzle for fire extinguishing.

54. High-pressure fine mist closed-loop system working principle: The pressure switch feedback system in the zone control valve box sends out a discharge signal, upon which the main unit receives the feedback signal and联动ly activates the spray indicator light.

55. Automatic startup of high-pressure fine mist system: When a fire occurs within the protected area, the fire detector detects the fire and sends a signal to the fire alarm controller. The fire alarm controller confirms the area of the fire based on the address of the fire detector, then sends a control signal to activate the fire extinguishing system, starting the high-pressure plunger pump and opening the corresponding section control valves.

56. Automatic start of high-pressure fine mist system: After the zone valve is opened, water in the system pipes quickly reaches working pressure (closed pre-action system waits for the closed sprinkler head to sense the bursting temperature, then the glass ball bursts automatically), and then sprays fine mist through high-pressure fine mist nozzles to extinguish fires.

57. Manual Electrical Start for High-Pressure Fine Mist System: Remote Start: When a fire is detected, before the fire detector activates, the electric valve button on the corresponding zone control valve box at the remote fire control center can be used to initiate the start of the zone valve. The water pump will automatically start to supply water and extinguish the fire.

58. High-pressure fine mist system manual electrical startup: Local startup: When a fire is detected, the partition control valve box can be locally opened to press the zone valve control button and open the zone valve for fire extinguishing.

Mechanical emergency start for high-pressure fine mist system: In the event of failure of the fire alarm system, the handle on the local valve can be manually operated to open the local valve for extinguishing the fire. Note: The emergency start of a closed fine mist system can be achieved by breaking the glass ball of the closed spray head.

60. High-pressure fine mist is produced by professional equipment under low design working pressure, and forms a mist with droplet accumulation distribution Dv0.99 less than 300μm on a plane 1m away from the nozzle. High-pressure mist has functions such as cooling, humidifying, dust prevention, fire prevention, and landscaping, and can be used in industrial, breeding, planting, and entertainment fields.

61. High-pressure fine mist fire extinguishing mechanism: Rapid cooling and partial asphyxiation – Advanced dual-action fire extinguishing mechanism: Water emitted from a nozzle made of a special material forms a mist with particle sizes between 10-100 micrometers, having a smaller surface area. Upon contact with fire, it vaporizes quickly, expanding in volume by 1700-5800 times, absorbing a large amount of heat and rapidly reducing the temperature of the burning surface; at the same time, the vaporized water forms steam, surrounding and covering the entire burning area, causing combustion to be asphyxiated due to oxygen deprivation.

62. The extinguishing mechanism of high-pressure fine water mist: With the heat absorption action calculated at 2257 kJ/kg for the latent heat of evaporation of water at 100℃, each fine water mist nozzle absorbs heat at a rate of approximately 300 kW for every 1 kg of fine water mist it sprays. This demonstrates its high heat absorption rate and strong cooling effect.

63. Suppression Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Aspirating action – when the fine water mist is heated and vaporizes, it expands rapidly to 1700~5800 times its original volume, creating a dense cloud of steam around the burning material. This forms a barrier that blocks the entry of fresh air. This deprivation of oxygen causes the combustion to cease.

64. Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: After the fine water mist evaporates, the resulting steam quickly envelops the burning material, flames, and smoke, effectively blocking the radiant heat of the flames, preventing the spread of the fire.

65. Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: The high-pressure fine water mist not only has the function of smoke and dust suppression but also washes away waste. This is because the ash, carbon particles, and harmful gases from combustion adhere to the fine water droplets, resulting in decontamination. Statistics show that in fire accidents, 70% of the deaths are not caused by direct burns but by the inhalation of high-temperature smoke and toxic gases.

66. Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Wetting Action – Explanation for extinguishing oil fires. The high-pressure fine water mist has a high particle velocity, allowing it to penetrate deep into the surface of the burning oil material, wetting the material and preventing the further generation of combustible gases. Additionally, due to the small size of the water mist particles, they do not disturb the liquid surface, causing splashes, thereby achieving the objectives of extinguishing the fire and preventing the spread of the fire.

67. Mechanism of fire extinguishing by high-pressure fine water mist: 3D movement—explaining its ability to fully or partially fill the protected area. During atomization, some of the smaller diameter droplets of the high-pressure fine water mist do not travel strictly along the jet direction; instead, they generate lateral and upward swirling movements within the upper space of the nozzle, allowing the fine water mist to fill the entire space of the protected area. The smaller the droplet size, the more pronounced the lateral transfer phenomenon. This is also referred to as 3D fire extinguishing.

68. Mechanism of extinguishing fires with high-pressure fine water mist: Explanation of its ability to extinguish electrical fires, and the reason why it doesn't conduct electricity when extinguishing electrical fires: The droplets are small in diameter (10-100 micrometers), and after being released, they are discontinuous and can remain suspended in the air for a long time. It takes a large quantity and a considerable amount of time for the mist to coalesce and condense, making it difficult to form a continuous conductive water flow or surface area on the electrode. Its resistivity is slightly lower than that of air.

69. An open-type fine water mist fire extinguishing system uses water as the medium and employs special atomizing nozzles to break the water stream into tiny droplets under specific pressure (usually 14Mpa) for fire suppression. It is a fixed fire protection system with features such as economy and wide application range, and has become an important technology to replace Halon fire extinguishing systems, offering a promising future for applications.
