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

49. Operation Principle of High-Pressure Fine Mist Open System: In the standby condition, the fine mist system maintains a certain pressure in the pipeline from the pump group outlet to the front of the zoning control valve box. When the pressure drops below the 1MPa set starting pressure of the pressure maintaining pump, the pump activates, ensuring the pipeline of the system maintains a stable pressure of (1-1.2) MPa.

50. Working Principle of High-Pressure Fine Mist Open System: Upon detection of a fire signal by the detector, the fire alarm control main unit transmits a signal to the electric ball valve within the pump group control cabinet and the electric ball valve in the zoning control valve box. The high-pressure plunger pump automatically starts up, and the electric ball valve in the zoning control valve box opens, allowing high-pressure water to flow through pipes and nozzles to form a mist for fire extinguishing.

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

52. Operating Principle of High-Pressure Fine Mist Closed System: 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 pipeline pressure drops and falls below the 1MPa set start-up pressure of the pressure maintenance pump, the pump is activated to keep the system pipeline at a stable pressure of 1-1.2MPa.

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

54. High-pressure fine mist closed-loop system operation principle: The pressure switch feedback system in the zoning control valve box triggers the spray signal, upon which the main unit receives the feedback signal and simultaneously activates the spray indicator light.

55. Automatic start 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 start the fire extinguishing system, initiating the high-pressure plunger pump and opening the corresponding section control valves.

56. Automatic startup of high-pressure fine mist system: After the section valve is opened, water in the system pipes quickly reaches working pressure (closed pre-action system waits for the closed spray head to sense the burst temperature, then the glass ball automatically bursts), and sprays by forming a mist effect through high-pressure fine mist nozzles, producing fine mist to extinguish fires.

57. High-pressure fine mist system manual electrical start: Remote start: When a person detects a fire, before the fire detector activates, the electric valve button of the corresponding section control valve box can be initiated from the remote fire control center to start the regional valve, enabling the pump to automatically start and supply water for fire extinguishing.

58. High-pressure fine mist system manual electrical start: On-site start: When a fire is detected, the local section control valve box can be opened to activate the area valve by pressing the area valve control button for fire extinguishing.

59. Mechanical emergency startup of high-pressure fine mist system: In the event of failure of the fire alarm system, the manual operation of the handle on the zone valve can be used to open the zone valve for extinguishing fires. Note: Emergency startup of the closed fine mist system can be achieved by breaking the glass ball of the closed sprinkler head.

High-pressure fine mist is produced by professional equipment under low design working pressure, forming a mist with droplet accumulation distribution Dv0.99 < 300μm on a plane 1m 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. Suppression Mechanism of High-Pressure Fine Water Mist: Rapid Cooling and Local Asphyxiation—Advanced Dual-Action Fire Suppression Mechanism: Water is emitted from a nozzle of a special material, forming a mist with particle sizes ranging from 10 to 100 micrometers, which has a smaller surface area. Upon contact with fire, it vaporizes quickly, expanding in volume by 1700 to 5800 times, absorbing a large amount of heat, and rapidly lowering the temperature of the burning surface; simultaneously, the vaporized water forms steam, enveloping and covering the entire combustion area, causing the fire to suffocate due to oxygen deprivation.

62. The extinguishing mechanism of high-pressure fine water mist: The heat absorption is calculated based on the latent heat of 100℃ water evaporation at 2257 kJ/kg. Each fine water mist nozzle absorbs heat at a rate of approximately 300 kW for every 1 kg of fine water mist emitted, demonstrating its high heat absorption rate and strong cooling effect.

63. Mechanism of extinguishing by high-pressure fine water mist: Asphyxiation. When the fine water mist is heated, it vaporizes and expands dramatically up to 1,700 to 5,800 times, enveloping the burning material with steam that tightly blocks the entry of fresh air. This creates a barrier that causes the combustion material to lack oxygen, thereby halting the combustion process.

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, providing strong resistance to the radiant heat of the flames, preventing the spread of the fire.

65. Suppression Mechanism of High-Pressure Fine Water Mist: The high-pressure fine water mist not only has a smoke and dust removal effect but also washes away waste. This is because the ash, carbon particles, and harmful gases from the combustion adhere to the fine water droplets, thereby being washed away. Statistics show that in fire accidents, 70% of the deaths are not caused by direct burns but by smoke and toxic gases from the high temperatures.

66. Mechanism of extinguishing by high-pressure fine water mist: Infiltration action—capable of extinguishing oil fires. The fine water mist particles have high speed, allowing them to penetrate deep into the surface of the burning oil, thereby wetting the fuel and preventing the further production of flammable gases. Additionally, due to the small size of the mist particles, they do not disturb the liquid surface, causing splashes, and thus achieve the goals of extinguishing the fire and preventing its spread.

67. Mechanism of extinguishing by high-pressure fine water mist: Three-dimensional movement — explanation for filling the entire or partial area for fire extinguishing. During the atomization of high-pressure fine water mist, some smaller diameter droplets do not all travel in the direction of the jet. The droplets produce lateral and upward swirling movements in the direction of the jet, entering the upper space of the nozzle. This allows the fine water mist to fill the entire space of the protected area. The smaller the particle size, the more intense the lateral transfer phenomenon. This is also known as three-dimensional fire extinguishing.

68. Fire Extinguishing Mechanism of 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), discontinuous upon release, and can remain suspended in the air for a long time. It takes a large quantity of water and a significant amount of time to coalesce and condense into mist, making it difficult to form a continuous conductive water flow or surface area on the electrode, with its resistivity slightly lower than that of air.

69. The open-type fine water mist fire extinguishing system utilizes water as the medium and employs special atomizing nozzles to break water streams into fine droplets under specific pressure (usually 14Mpa) for fire extinguishing. It is a fixed fire extinguishing system with characteristics such as economy and wide applicability, and has become a significant technology to replace Halon fire extinguishing systems, boasting a promising application prospect.

70. Composition and Working Principle of High-Pressure Fine Water Mist: The fine water mist fire extinguishing system consists of a high-pressure fine water mist storage tank, a pump unit for the fine water mist fire extinguishing system (including a high-pressure main pump, a high-pressure standby pump, a pressure regulator pump, a control cabinet for the pump unit, an inlet solenoid valve, an inlet filter, and a regulating water tank), a water replenishment system, a water supply network, a group of fine water mist fire extinguishing system zone control valves, fine water mist nozzles, high-pressure fine water mist pipes, and a fire detection and alarm system.
