Principle of Fine Mist Fire Extinguishing System
Release time:
Mar 25,2025
In the quasi-working condition, the water mist system from the pump group outlet to the area valve in front of the pipe network (closed from the pump group outlet to the nozzle of the pipe network) to maintain the pressure, when the pressure is lower than the pressure regulator pump is set to start the pressure of 8 bar, the pressure regulator pump to start, so that the system to maintain a stable pressure network (8-14) bar, the pressure regulator pump running for more than 10 seconds after the pressure is still less than 14 bar, the fine water mist fire extinguishing system work! Principle, the main pump starts, the pressure regulator pump stops.
The water tank inlet is connected to the water replenishment solenoid valve, water through the filter and water replenishment solenoid valve into the water tank; water tank is equipped with a liquid level controller to realize the automatic control of the water level of the water tank. The water replenishment solenoid valve opens when the water level of the tank is low and closes when the water level is high. Through the pump group control panel, realize the high pressure water mist fire extinguishing system start, stop and system operation monitoring.
When the automatic fire alarm system detects and confirms the fire, (0~30 seconds) after the linkage to open the corresponding area of the motorized valve, the pressure in the pipeline network drops rapidly, and the high-pressure pumping unit starts. In order to ensure the reliable operation of the system, in line with the design specifications, the regional motorized valve start can also be realized by manual, electric or remote linear start; high-pressure pumping unit can also be manual, linkage or remote linear start.
