一、坠落试验 将CNG空瓶升至3m或更高的空中,向水泥地上反复进行坠落摔打,然后进行10%~100%的工作压力下水 循环13000次,不出现裂纹为合格。
The CNG empty bottles, falling test reach 3 m or higher in the air, to cement the ground again and again to break a fall, and then to 10% ~ 100% of the working pressure water loop 13000 times, don't appear crack for qualified.
二、枪击试验 将CNG样瓶充入25Mpa的天然气,在距离46m处用速度为853m/s、口径为0.3in的空甲弹,对瓶体进行45 度的射击。气瓶不应出现裂纹。
Second, the shooting test will CNG gas bottle filling the 25 mpa, at 46 m distance with the rate of 853 m/s, caliber 0.3 in the empty shell, shooting at an Angle of 45 degrees on the bottle. Gas cylinders should not appear crack.
三、此外,气瓶还装有安全阀,其内装有100℃的易熔合金和26Mpa的爆破片。当气瓶内气体压力、温度超过上述数值时会自动放气。 虽然压缩开然汽车发展时间还不长,但现在世界上也有约100多万辆CNG汽车,还没有见到在运行中因 交通事故引起气瓶爆炸失火的记录。因此压缩天然气汽车比汽油汽车更加安全。
Three, in addition, the cylinder is equipped with safety relief valve, which is equipped with 100 ℃ of fusible alloy and 26 mpa blasting. When the gas pressure in the cylinder, the temperature exceeds the above numerical automatically deflated. Although compression and automobile development time is not long, but now is about more than 100 CNG car in the world, also not seen in the operation of the gas cylinder explosion caused by traffic accident was on fire. So the compressed natural gas vehicle than gasoline cars safer.
