船舶特种细水雾灭火系统中的微差全引射技术研究

为实现新型的船舶特种细水雾灭火技术,特提出并深入研究了微差全引射技术。另外,还建立了一套专用的引射器多级试验装置,进行了大量的试验和理论分析,得出了微差全引射技术中引射器串联级数的确定方法、系统全压缩比在各级间的分配方法、各级喷射器类型的选择原则、设计点的确定原则以及主要关键尺寸的计算方法。

A Tiny-pressure-difference Full Ejectors Technique in Marine Special Fine Water Mists Fire Fighting System

To develop the new type of marine special fine water mists fire fighting technique, tiny-pressure-difference full ejectors technique (TFE) was researched. A set of experimental ejectors was built and a number of tests were carried out. The methods of determining the number of ejector stages in series and assigning compression ratios among the stages, the principles of choosing ejector types and defining design key points as well as the method of calculating main dimensions were obtained. This designed full ejectors system can work efficiently and provide key device for marine fine mist fire fighting technique.
