Ultra-high-speed deluge fire suppression technology plays a crucial role in rapidly extinguishing fires, controlling the spread of fire, and minimizing accident-related losses.The applications of ultra-high-speed deluge-fire suppression technology in explosives and ammunition production facilities were summarized by examining the hazardous characteristics of these sites, the potential consequences of accidents, and the corresponding safety protection requirements during production. The types, composition, and features of ultra-high-speed deluge systems used in the United States, along with their current application status and research progress in explosive and ammunition manufacturing facilities were also introduced. The fire hazard characteristics of weighing and loading production sites was studied for explosives and ammunition in the United States, along with the installation requirements for ultra-high-speed deluge systems. Furthermore, the current development status and existing challenges of ultra-high-speed deluge fire suppression technology applied in China’s explosives and ammunition production facilities were summarized. Future research directions are outlined, focusing on optimizing system response time, enhancing detector performance, establishing system design standards, and promoting the adoption of integrated suppression systems. A valuable reference was provided for the research and practical application of ultra-high-speed deluge fire suppression technology in China’s explosives and ammunition production facilities.

先导式超高速雨淋系统[40]于20世纪60年代初问世,主要用于美国国家航空航天局(National Aeronautics and Space Administration,NASA)载人航天计划的高压舱和海军舰艇弹药库防护系统,早期系统响应时间为150 ms,经过多年发展与改进,如今系统响应时间可以达到100 ms以内,该系统主要应用在火炸药切药及弹药生产场所。系统由高速火焰探测器、控制系统、高速电磁阀启动的先导式系统、喷头、系统管道、供水系统等部分组成。先导式系统包括高速电磁阀、先导式阀门(图5)[32]、系统管道、系统阀门等部分组成。先导式超高速雨淋系统主要特点是先导式阀门同时连接雨淋系统和先导式系统,雨淋系统管道预充水至喷头处,先导式系统对先导式阀门施加压力防止喷头喷水。高速火焰探测器接收到火灾信号后,控制系统启动先导式系统上的高速电磁阀,先导式系统开始排水并泄压,先导式阀门开启,喷头开始喷水。系统响应时间与喷头数量、供水压力、高速电磁阀与先导式阀门之间距离等因素有关,系统最大喷头数量不超过10个。系统形式如图6所示[32]。
