New engine compartment automatic fire extinguishing device

At present, the existing fixed fire extinguishing devices in the market are mostly driven by a single, single nozzle, the time for continuous fire extinguishing agent is short, and the protection scope is small, and it is easy to cause secondary re-ignition fire. Generally, in the protected fire zone, When prescribing a fixed fire extinguishing device, the fire extingui If the range of protection is large, multiple fire extinguishing devices should also be preset, and all fire extinguishing device nozzles should be pre-aligned with protective objects. At the same time, multiple fire extinguishing devices must be linked through the connecting line to achieve simultaneous start-up and simultaneous fire extinguishing agent. In order to ensure the effective and complete protection of the protection of the fire.

Obviously, the fire extinguishing device described above requires a multi-directional three-dimensional protection position from the occurrence of a fire to a safe and effective extinguishing in a protected area. If a single fire extinguishing device is used, it is difficult to effectively extinguish the fire at one time, and when multiple fire extinguishing devices are used in linkage activation , Prone to occur in the event of a fire, the linkage start-up circuit may be burned out, the fire extinguishing device cannot be started in linkage or the linkage start is not timely, so that the protection scope of a single fire extinguishing device is insufficient, and the early fire cannot be extinguished early in the fire. , resulting in the spread of fire over the fire area or the consequences of the formation of secondary rekindling fires.

China Automobile Passenger Car Parts (Xiamen) Co., Ltd. solves the deficiencies of the existing technology and provides a dual-drive multi-spout pipe network automatic fire extinguishing device FZBA_-C/GW, which adopts double-acting output fire extinguishing agent and uses multi-spout pipe network type. The fire extinguishing agent technical plan can spray the fire extinguishing agent in multiple directions quickly to the protection object, and perform all-round protection of the protection object. The dual-drive jet fire extinguishing agent can make the effective extinguishing agent injection time longer and effectively inhibit the secondary reactivation of the ignition point. . With a wide range of effective protection and low cost of use, it is a new generation of highly efficient and scientific energy-saving fire extinguishing products.

The device consists of ultra-fine dry powder fire extinguishing agent, drive medium, double extinguishing agent tank, constant pressure release valve, multi-jet hose, initiator assembly (thermal initiating assembly, electric initiating assembly optional) and other components, which are stored without pressure. It is designed for automatic fire extinguishing in narrow spaces such as ships, automobile engine compartments, battery compartments, baggage compartments, power distribution cabinets, etc. It is a kind of high-temperature easy-to-fire site installed in ships, automobile engine compartments, battery compartments, luggage compartments, power distribution cabinets, etc. , Has a certain ability to resist earthquakes and is suitable for harsh working conditions. This device performs all-weather automatic monitoring of protected objects under unattended conditions. When the fire occurs in ships, automobile engine compartments, battery cabins, baggage compartments, power distribution cabinets and other places, the fire extinguishing is started automatically, and a self-checking system for work effectiveness and a fire detection and alarm system are available. The fire extinguishing device with the charged ignition module can also manually start the fire extinguishing device through an optional start switch.
