高压细水雾灭火系统根据供水方式和应用形式可分为多种类型，主要包括泵组式系统和瓶组式系统。泵组式高压细水雾灭火系统通过高压泵组持续供水，适用于需要长时间持续喷雾的场所；瓶组式系统则依靠储存在高压容器中的水和驱动气体工作，适用于供水条件受限或需要快速响应的场合。两种系统各有优势，设计时应根据具体工程条件合理选择。
The high-pressure fine water mist fire extinguishing system can be divided into various types according to the water supply method and application form, mainly including pump group system and bottle group system. The pump set high-pressure water mist fire extinguishing system supplies water continuously through the high-pressure pump set, which is suitable for places requiring long-term continuous spray; The bottle group system relies on water and driving gas stored in high-pressure containers to work, and is suitable for situations where water supply conditions are limited or rapid response is required. Both systems have their own advantages, and the design should be reasonably selected based on specific engineering conditions.
在系统类型方面，开式细水雾系统包括一齐喷系统和雾幕系统（也称线性应用方式），闭式细水雾系统则分为湿式系统和预作用系统。开式系统在火灾发生时所有喷头同时动作，适用于全淹没灭火；闭式系统则仅火灾区域附近的喷头动作，具有更强的针对性和更小的水渍损失。轨道交通车辆乘客区高压细水雾灭火装置应采用开式系统应用方式，每节车辆宜设为一个防护分区。
In terms of system types, open type fine water mist systems include simultaneous spraying systems and mist curtain systems (also known as linear application modes), while closed type fine water mist systems are divided into wet systems and pre action systems. The open system operates all nozzles simultaneously in the event of a fire and is suitable for total flooding fire extinguishing; A closed system only operates the nozzles near the fire area, which has stronger targeting and smaller water damage. The high-pressure fine water mist fire extinguishing device in the passenger area of rail transit vehicles should adopt an open system application method, and each vehicle should be set as a protective zone.
高压细水雾灭火系统的维护管理是确保其长期可靠运行的关键。根据规范要求，应通过试验阀对泵组式系统进行放水试验，检查泵组启动、主备泵切换及报警联动功能是否正常。应检查瓶组式系统的控制阀动作是否正常。还应定期检查管道和支吊架是否松动，管道连接件是否变形、老化或有裂纹。对于泵组式系统，还需关注高压柱塞泵的运行状态、过滤器清洁程度以及系统压力的稳定性。
The maintenance and management of high-pressure fine water mist fire extinguishing systems are key to ensuring their long-term reliable operation. According to the regulatory requirements, a water discharge test should be conducted on the pump group system through a test valve to check whether the pump group startup, main and backup pump switching, and alarm linkage functions are normal. The control valve of the bottle group system should be checked for normal operation. Regular inspections should also be conducted to ensure that pipelines and supports are not loose, and that pipeline connections are not deformed, aged, or cracked. For pump group systems, attention should also be paid to the operating status of high-pressure plunger pumps, the cleanliness of filters, and the stability of system pressure.
随着技术进步和工程实践的深入，高压细水雾灭火系统的应用范围不断拓展。河南省于2026年7月1日实施的新版《高压细水雾灭火系统技术标准》（DBJ41/T074-2026），在原有规范基础上补充了新型应用场所，通过工程案例和实体火灾试验细化了不同应用场所的设计参数。这一修订使高压细水雾灭火系统的技术特点与工程项目实际更好地结合。未来，高压细水雾灭火系统将在数据中心、档案馆、轨道交通、综合管廊、粮食仓储等更多领域发挥重要作用，其快捷、环保、安全的优势将进一步得到彰显。
With the advancement of technology and the deepening of engineering practice, the application scope of high-pressure fine water mist fire extinguishing systems continues to expand. The new version of the "Technical Standard for High Pressure Water Mist Fire Extinguishing Systems" (DBJ41/T074-2026), which will be implemented in Henan Province on July 1, 2026, supplements the existing specifications with new application scenarios and refines the design parameters for different application scenarios through engineering cases and physical fire tests. This revision better integrates the technical characteristics of high-pressure fine water mist fire extinguishing systems with the actual engineering projects. In the future, high-pressure fine water mist fire extinguishing systems will play an important role in more fields such as data centers, archives, rail transit, comprehensive pipe galleries, and grain storage, and their advantages of high efficiency, environmental protection, and safety will be further demonstrated.
