摘要
为研究新型灭火产品灭火管在实际应用过程中,布置方式、爆破口位置等因素对灭火效果的影响程度,采用相关标准规定的试验方法测定预贮存压力分别为0.8、1.2 MPa的灭火管的静态动作温度,并采用火灾实体试验的方法,对比分析了七氟丙烷灭火管和全氟己酮灭火管动作后的喷射剩余率及灭火情况。研究结果表明:灭火管内部预贮存压力越高,其爆破动作越早,静态动作温度也相对越低;布置方式、爆破口位置对七氟丙烷灭火管喷射剩余情况的影响比对全氟己酮灭火管的影响小;布置方式、爆破口位置对七氟丙烷灭火管灭火效果的影响也比对全氟己酮灭火管的影响小。
In order to study the influence of factors such as layout and blasting port location on the fire extinguishing effect of the new fire extinguishing product fire extinguishing tube in the actual application process,the static operation temperature of the fire extinguishing tube with the pre-stored pressure of 0.8 MPa and 1.2 MPa respectively was measured by the test method specified in the relevant standards.The residual rate and fire extinguishing conditions of HFC227eea fire extinguishing tube and FK-5-1-12 fire extinguishing tube were compared and analyzed by fire entity test.The results show that the higher the pre-stored pressure,the earlier the blasting action and the lower the static temperature.The influence of the layout and blasting port location on the residual situation of the HFC227eea fire extinguishing tube is less than that of the FK-5-1-12 fire extinguishing tube;The influence of layout and blasting port location on the fire extinguishing effect of HFC227eea fire extinguishing tube is also smaller than that of FK-5-1-12 fire extinguishing tube.
