编辑同志:我队前几年买了一部解放牌干粉消防车,经试用,效果极好。按要求,每三个月应检查一次该车的氮气(N_2)钢瓶的压力,若压力低于120kg/cm~2时,应重新充气。可是充气要到外地,实在不便,而我们单位有二氧化碳(CO_2),能否用CO_2代替N_2呢?鲁化消防队长王家成作为干粉灭火剂的发射动力气体,从理论上来讲,只要是不助燃的惰性气体均可。一般选用N_2或CO_2是因为这两种气
Editor’s Comrade: A few years ago I bought a brand liberation card dry powder fire truck, the trial, the effect is excellent. On request, the car should be checked every three months nitrogen (N2) cylinder pressure, if the pressure is lower than 120kg / cm2, it should be re-inflated. However, inflatable to the field, it is inconvenient, and our unit has carbon dioxide (CO_2), can use CO_2 instead of N_2? Luhua Fire Chief Wang Jiacheng as dry powder fire extinguishing agent launch kinetic gas, in theory, as long as it is not combustion The inert gas can be. Generally choose N_2 or CO_2 because of these two kinds of gas
