46. The pipeline system of the high-pressure fine water mist fire suppression system uses stainless steel pipes (304) with rust-resistant properties, 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, thus, after the pipeline installation, rigorous flushing, pressure testing, and blow cleaning must be conducted. All pipes are焊接 using the tungsten inert gas (TIG) welding process.

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

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

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

49. Working Principle of High-Pressure Fine Mist Open System: 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 before the zone. When the pressure drops below the set start pressure of the pressure maintaining pump by 1 MPa, the pressure maintaining pump activates, ensuring the pipeline of the system maintains a stable pressure of (1-1.2) MPa.

50. High-pressure fine mist open system working principle: Upon detection of a fire signal by the detector, the fire alarm control main unit transmits the signal to the electric ball valve within the pump group control cabinet and 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 fire extinguishing.

51. Working Principle of High-Pressure Fine Mist Open System: The pressure switch feedback system inside the zoning control valve box triggers the discharge signal, and upon receiving this feedback, the main unit activates the spray indicator light.

52. Working Principle of High-Pressure Fine Mist Closed System: In the standby condition, the fine mist system maintains a certain pressure within the pipeline from the pump group outlet to the valve control box before the division. When the pipeline pressure drops and falls below the set start-up pressure of the pressure maintenance pump (1 MPa), the pressure maintenance pump activates to keep the system pipeline at a stable pressure (1-1.2 MPa).

53. Working Principle of High-Pressure Fine Mist Closed System: Upon detecting a fire signal, the fire alarm control unit transmits the signal to the pump group control cabinet. The high-pressure plunger pump starts, and the electric ball valves within the section control valve box are opened. The entire pipeline is filled with high-pressure water. When the glass ball in the closed 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 zoning 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 activation of high-pressure fine water 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 fire detector's address and then sends a control signal to activate the fire extinguishing system. This initiates the high-pressure plunger pump and opens the corresponding zone control valves.

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

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

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, and the zone valve control button pressed to open the zone valve for extinguishing.

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

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 suppression, and landscaping, and can be used in industries, animal husbandry, agriculture, and entertainment fields.

61. Suppression Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Rapid Cooling, Local Asphyxiation—Advanced Dual-Action Fire Suppression Mechanism: When water is emitted from a nozzle of a special material, it forms a mist with particle sizes between 10-100 micrometers, with a small specific surface area. Upon contact with fire, it rapidly vaporizes, expanding in volume by 1700-5800 times, absorbing a large amount of heat and quickly lowering the temperature of the burning surface; at the same time, the vaporized water forms steam, enveloping and covering the entire combustion area, causing the fire to be asphyxiated due to oxygen deprivation.

62. The extinguishing mechanism of high-pressure fine water mist: Based on the latent heat of water evaporation at 100°C, which is 2257 kJ/kg, each fine water mist nozzle can absorb 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. Suppression Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Aspiration effect - upon heating, the fine water mist vaporizes and expands rapidly to 1,700 to 5,800 times its original volume, enveloping the burning material with a dense steam barrier that prevents the entry of fresh air. This deprivation of oxygen interrupts the combustion of the material.

64. Suppression Mechanism of High-Pressure Fine Water Mist: 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 and preventing the spread of the fire.

65. The fire extinguishing mechanism of high-pressure fine water mist: The high-pressure fine water mist not only has a smoke and dust suppression effect but also acts as a cleaner for smoke and debris. This is because the ash, carbon particles, and harmful gases from the fire adhere to the fine water droplets, thereby being cleaned and neutralized. Statistics show that in fire accidents, 70% of the fatalities are not directly killed by the fire but rather asphyxiated by the hot smoke and toxic gases.

66. Mechanism of extinguishing by high-pressure fine water mist: The wetting action—capable of extinguishing oil fires. The fine water mist particles are fast, allowing them to penetrate the surface of the burning oil, thereby wetting the fuel and preventing the production of more flammable gases. Additionally, due to the small size of the mist particles, they do not disturb the liquid surface, causing splashes, and achieve the purpose of extinguishing fires and preventing their spread.

67. Mechanism of Fire Extinguishing by High-Pressure Fine Water Mist: Three-dimensional Movement — Explanation for Full or Partially Filling the Protection Area. During the atomization of high-pressure fine water mist, some smaller diameter droplets do not travel solely in the direction of the jet. They generate lateral and upward movement 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 three-dimensional fire extinguishing.

68. The fire extinguishing mechanism of high-pressure fine water mist: Explanation of its ability to extinguish electrical fires and why it doesn't conduct electricity when extinguishing electrical fires: The droplet diameter is small (10-100 micrometers), and after being emitted, it is discontinuous and can remain suspended in the air for a long time. It takes a large quantity and considerable time to gather and condense into water mist, making it difficult to form a continuous conductive water stream or surface water on the electrode, and 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 with the help of special atomizing nozzles operating at specific pressure (typically 14Mpa), breaks the water flow into fine droplets for fire suppression. It is a fixed fire protection system featuring economy and broad application range, and has become a significant technology to replace Halon fire suppression systems, holding a promising future in various applications.
