摘要:
为提高火帽发火可靠性,对击发药的吸湿性、装药量、耐压性、壳底厚度、装配工艺等影响因素进行分析和验证。结果表明:击发药装药量小,火帽输出能量降低;击发药、火帽壳、加强帽受潮,对火帽输出能量的降低影响较大;压药压力过低,针刺感度随之下降。同时,通过不同条件下的药盘点火试验,确定了正确判断火帽发火不可靠的条件。击发药装药量为28~32 mg,压药压力为180~310 MPa,药剂与管壳在装配前进行烘干,火帽能实现可靠发火。
Abstract:
In order to improve the ignition reliability of a detonating cap, factors including moisture absorption, charge quantity, bottom thickness of shell and assembly technique were tested and analyzed. Results show that small charge quantity reduces the output energy of the detonating cap. Meanwhile, Moisture absorptions of charge, detonating cap shell and strengthen cap have significant impact on the output energy decrease. Low charge pressure leads to a reduction of acupuncture sensitivity. Subsequently, via ignition test of charge plate under different conditions, optimum method of judging ignition reliability of the detonating cap was determined. When the charge is 28-32 mg, charge pressure is 180-310 MPa, and the charge and cube are dried before assemblage, the detonating cap could ignite steadily. It could provide references to the optimization of assembly technology to improve ignition reliability of the detonating cap.
