在长30m,公称直径(Dg)分别为50、65、80和100mm的管道内,进行了C_2H_2分解爆轰实验。用O_2—C_2H_2爆轰波引爆C_2H_2,测量了管道内的爆轰压力,及在管道端面上的反射压力。与以前认为在管径500mm管道内不会出现自持的C_2H_2分解爆轰的意见相反,在这样的管道内也发生了C_2H_2分解炸轰。在管端测到了1700kg/cm~2的异常高压,并对数次异常高压的破坏威力作了记录。
The detonation experiment of C_2H_2 was carried out in the pipes with the length of 30m and the nominal diameter (Dg) of 50, 65, 80 and 100mm respectively. The O_2-C_2H_2 detonation wave was used to detonate C_2H_2, and the detonation pressure in the pipeline and the reflection pressure on the pipe end surface were measured. Contrary to what was previously thought of as a detonation of C_2H_2 that does not appear self-sustaining within a pipe of 500 mm diameter, C_2H_2 decomposition and detonation also occur in such a pipe. An abnormal high pressure of 1700 kg / cm ~ 2 was measured at the pipe end, and the destructive power of abnormal high pressure was recorded.
