摘　　要：设计了可燃气体动态爆炸极限测试装置,通过调节两个气体流量计来控制可燃气体和空气的流速,使二者达到一定的混合比例,在不间断供气的情况下使混合气体在燃爆管中保持流动状态。装置除了可以测定可燃气体的动态爆炸极限以外,还可以测定最小点火能、动态爆炸压力及压力上升速率,及对可燃气体动态爆炸火焰进行微观研究。已有的试验数据表明本装置设计合理,安全可靠。The combustible gas dynamic explosion limit test device was designed.By regulating the two gas flowmeter,the flow of combustible gas and air were controlled,to reach certain mixing ratio,and remain flow state the mixed gas in the detonator under the condition of uninterrupted supply of gas.Using this device,not only the combustible gas dynamic explosive limit,but also the minimum ignition energy,dynamic explosive pressure and pressure rise rate can be tested,and it can conduct a microcosmic study on the flame of combustible gas explosion.The existing test data show that the device design is reasonable,safe and reliable.
