自动灭火装置是为了防止装燃油炉的车辆在发生事故时燃料流出酿成火灾而研制的。一、第一次试制 1977年开始研制自动灭火装置。该装置的探测部分试用振子开关、水银开关;接受指令启动灭火回路部分试用喷射电磁阀;并试用氮气、水和泡沫水做灭火剂。试验结果,由于车辆运行的横摆加速度原因,振子开关发生误动作,水银开关试验效果良好。又试验证明,氮气不能充分冷却燃烧筒,水和泡沫水效果好。上述研究达到目的,但因装置结构复杂,造价高,没能实用。
Automatic fire extinguishing device is designed to prevent fuel-fired furnace vehicles in the event of fuel outflow caused by a fire developed. First, the first trial In 1977 began to develop automatic fire extinguishing device. The device detection part of the trial oscillator switch, mercury switch; accept the order to start the fire circuit part of the pilot injection solenoid valve; and try nitrogen, water and foam water to do fire extinguishing agent. Test results, due to the yaw acceleration of the vehicle running, vibrator switch malfunction, mercury switch test results. And test proved that nitrogen can not fully cool the combustion tube, water and foam water effect. The above research achieves the goal, but because of the complicated device structure and high cost, it is not practical.
