针对某组合延期装置的结构,分析了延期精度的影响因素。研究表明:采用低爆速塑料导爆管以及尺寸合适的消爆气室有利于提高延期精度;在结构设计及延期药成分配比等固定的条件下,采用真空干燥方法干燥药剂对提高延期精度有显著效果。 Aiming at the structure of a combination deferred device, the influencing factors of deferred accuracy are analyzed. The research shows that using low detonation speed plastic detonating tube and dehumidification gas chamber with proper size will help to improve the delaying accuracy. Under the fixed conditions of structural design and delaying the composition of drug, vacuum drying method is used to improve the delay precision Significant effect.
