摘　　要：在实际应用中,很多安装了爆破片装置的工况无法满足泄放系数法所规定的条件,而必须采用流体阻力系数法进行泄放能力的计算。首先根据气体动力学及流体力学原理对爆破片装置流体阻力系数的计算进行理论分析与推导,并采用临界流文丘里喷嘴的流量测量方法建立了爆破片装置流体阻力测试系统,该测试系统主要由流量测试系统和阻力测试系统两部分组成。以50mm口径的爆破片装置为研究对象,选用压缩空气为试验介质,在标准试验条件下准确地测量出试验介质的流量,并以此计算出爆破片装置的流体阻力系数。Many working conditions of devices installed with bursting disc cannot meet the conditions specified by the discharge coefficient in practical application,and the method of fluid resistance coefficient has to be used to calculate the discharge capacity. In this paper,the calculation of the fluid resistance coefficient of bursting disc devices was analyzed theoretically and deduced based on aerodynamics and hydrodynamics,and then the flow measurement method of critical flow Venturi nozzle was used to build up the fluid resistance test system for bursting disc device,which is composed of flow measurement system and resistance test system. Finally,by taking bursting disc devices of 50 mm diameter as research object and using compressed air as the test medium,the flow rate of the test medium was accurately measured under the standard test condition of bursting disc,and the fluid resistance coefficient of bursting disc devices was calculated accordingly.
