高分子水凝胶灭火剂灭火作战性能测试

Research on performance test of polymer hydrogel fire extinguishing agent

搭建实验平台,将喷射水凝胶达到常规作战喷射距离(15、17 m)时的车载泵压、水枪进口压力、水带流量与喷射水时的对比,检验高分子水凝胶灭火剂与水的区别,以及是否会对实际作战产生影响;并在此过程中测量水带压差,并计算出相应的阻抗系数值,比较两者阻抗系数值,分析其原因。实验结果得出了在相同条件下,喷射水凝胶所需泵压与喷射水时的泵压的关系,以及喷射两种不同灭火剂时的充实水柱的不同,对比了在相同条件下,相同口径、材质的水带运输水凝胶时的阻抗系数值与运输水时的阻抗系数的大小。

An experimental platform was built to compare the injection pressure of the jet hydrogel to the conventional injection distance(15, 17 m), the inlet pressure of the water gun, the water flow rate and the corresponding parameters of the jet water. The difference between the polymer hydrogel fire extinguishing agent and the water was tested, and whether it would affect the actual operation. Measure the water pressure difference, calculate and compare the corresponding impedance coefficient, and analyze the reasons. The experimental results show that under the same conditions, the relationship between the pump pressure and the required pump pressure of the ejection hydrogel, and the difference between the two kinds of fire extinguishing agents when they are injected,and the resistance coefficient of the two kinds of fire extinguishing agents with the same caliber and material are compared.
