本装置为矿用隔爆兼本质安全型,适用于煤矿中含有爆尘及爆炸性 气体(CH4)的场合,作为皮带运输机的低速、超温、烟雾、满煤、堆煤、跑偏、撕带等事故的综合保护和系统多台皮带机间集中控制及报警通讯之用。配有超温 烟雾自动洒水灭火装置。采用语言加灯光报警方式,新颖独特。
接上电源后,其绿灯亮,待稳定10分钟后,绿灯灭红灯亮,表示检测探头热稳定时间结束,传感器进入检测状态。当有少量烟雾进入烟室后,红灯闪亮,同时控制三级管导通,输出低电平,使继电器闭合。实现烟雾保护或自动灭火。
When the power supply is connected, the green light will be on. When it is stable for 10 minutes, the green light will be off and the red light will be on, indicating that the detection probe thermal stability time is over and the sensor enters the detection state. When a small amount of smoke enters the smoke chamber, the red light will flash, and at the same time, the third level pipe will be controlled to be on, and the output low level will make the relay close. Realize smoke protection or automatic fire extinguishing.
烟雾传感器主要用于对煤矿井下橡胶、煤尘等因摩擦起热或其它原因产生的烟雾进行监测。本传感器采用先进的气敏型探头,经过电路处理后。具有可靠、无误动等特点。外壳小巧玲珑,使用方便,是目前烟雾报警的理想部件。
The smoke sensor is mainly used to monitor the smoke produced by rubber, coal dust and other reasons due to friction and heating. The sensor adopts advanced gas sensitive probe and is processed by circuit. It has the characteristics of reliability and no misoperation. The shell is small and exquisite, easy to use, and is the ideal component of smoke alarm at present.
