气体报警器中探测器的安装
探测器在安装时首先要弄清楚监测区域内可燃气体可能的泄漏点,分析出泄漏压力、泄漏量以及方向等因素。还需弄清楚适用的燃气种类,比较泄漏气体的密度与空气密度的大小。因为天然气和煤制气比空气轻,泄漏后会向上飘,相反液化石油气比空气重,泄漏后会下沉,根据这些因素选定探测器安装的高度;其次是依据监测区域的大小和空间高度等因素,确定探测器的安装数量,保证在可燃气体泄漏时覆盖每一个位置,防止出现监测盲区。
可燃气体报警器要检测可燃气体,探测器和检测环境沟通是必然的,所以环境中的灰尘和水汽进入探测器是无法避免的,为了避免灰尘和水汽进入而损坏探测器控制器,在探测器安装完成后,一定要安装透气防护罩。
气体报警器中控制器的安装
在安装报警控制器时,首先要检查周围是否有强电磁场,如果有,不能进行安装,其次,在可燃气体泄漏时报警控制器会出现声光报警,在安装时应安装在便于负责人员看到和听到的地方,或是安装在有值班人员的地方,以便发生可燃气体泄漏时能够及时发现,并通知相关人员进行处理,还有就是报警控制器需要定期维护,因此在安装时应安装在便于负责人员维护的高度,一般应在(160~170)cm。
