摘要
为进一步拓宽引射器的应用领域,研制了一种出入口压差小,且不从级间引走部分介质的新型多级引射技术。设计了一套实验装置,通过大量实验分析探讨了串联级数的确定、设计点的选择、总增压比的分配、各级喷射器类型的选定、以及如何计算各主要尺寸等关键技术问题,是这一新型技术深入研究和应用的基础。它在某些特种军事装备和油田轻烃回收等重要领域的成功应用,表明了独特的优良性能和广阔的应用前景。
The new type of gas multistage-ejectors have been used in military affairs for defense and in oil field for light hydrocarbon recovery. After introducing the test device of this type of ejectors, this paper offers how to select the count of multistage-ejectors, how to assign the full compress ratio, how to select the type of ejector, how to fix on the design point, and how to calculate all key sizes of ejectors. All of them come from large numbers of tests and they are the keys for the design of this new type of multistage-ejectors.
