一种电力机车用泵组式灭火系统及其控制方法
By combining non-pressurized liquid storage containers with pumping devices, an active fire extinguishing system integrating sealed pressure equalization, redundant liquid supply, and intelligent graded control was constructed. This solved the high-pressure risks and single-function problems of traditional pressurized systems, achieved intelligent graded response and highly reliable fire extinguishing, and avoided secondary accidents.

AI Technical Summary
Traditional pressurized fire extinguishing systems suffer from high pressure risks, pressure decay, and limited functionality. They cannot provide graded responses based on fire size and pose an explosion hazard in high-temperature environments. Existing pump-type systems lack in-depth adaptation and safety redundancy design.
By combining non-pressurized liquid storage containers with pumping devices, along with precision pipelines and control components, an active fire extinguishing system is constructed that integrates sealed pressure equalization, redundant liquid supply, and intelligent hierarchical control. The fire extinguishing controller integrates multi-source information for accurate perception and hierarchical response, and adopts a dual-pump redundancy design and ring bus communication to ensure system reliability.
It eliminates the risk of high-pressure storage, realizes intelligent graded fire suppression, improves system reliability and safety, avoids secondary accidents, can flexibly respond to large-area fires and optimize the dosage of fire extinguishing agents, and has dynamic anti-reignition capabilities.
