System components and working principle of closed fire extinguishing system
Release time:
Mar 25,2025
System components:
Closed high pressure water mist fire extinguishing system including full flooding application mode and local application mode, is the use of closed water mist nozzle, by supporting the automatic fire alarm system automatic chain or remote control, manual start, control a group of nozzles at the same time spraying water automatic water mist fire extinguishing system.
Closed system working principle:
In the quasi-working condition, high-pressure water mist fire extinguishing system from the pump group outlet to the nozzle before the pipe network, maintaining a certain pressure, when the closed-type nozzle glass bubble temperature reaches the action temperature, the glass bubble broken, the pipeline pressure drop, when the pressure is lower than the pressure regulator pump is set to start the pressure, the pressure regulator pump to start, so that the system network to maintain a stable pressure, the pressure regulator pump running for more than a certain period of time after the network pressure is still less than, the main pump to start, the pressure regulator pump to stop, the main pump to start, the pressure regulator pump to stop. The main pump starts and the pressure stabilizing pump stops. The flow switch feeds back the system spraying signal, and the host receives the feedback signal and turns on the spraying indicator.
