nttttt《
火力发电厂与
变电所设计防火规范》(GB-50229-96)在第9.3.3条规定“电缆夹层及电缆竖井宜设置悬挂式气体自动装置”，在第9.4.2条规定“重要的无人值班的变电所，宜设置悬挂式气体
自动灭火装置”。据调查了解，上述这些场所大多数因为规模不大或因为设置有困难而未设置固定式
自动灭火系统，同时也未按规定设置悬挂式气体自动灭火装置。这是因为目前悬挂式气体自动灭火装置均为“
哈龙”产品，即将面临淘汰，目前又无理想的气体类替代品。致使这些部位处在一种无自动灭火装置保护的状态下，一旦发生火灾就有可能扩大蔓延。国内外一些冶金钢铁企业就曾多次发生过电缆夹层和隧道的火灾，造成了重大损失。即使是这些部位可以设置固定式气体自动灭火装置，也因其保护范围和对环境的要求高而使得建设投资和
运行成本较高。超细干粉自动灭火装置的问世在一定程度上填补了目前无理想的悬挂式气体
自动灭火装置的空白，弥补了固定式气体自动灭火装置在使用上的一些局限性。ntttt
nttttt传统固定式气体灭火系统把较大封闭空间的房间作为防护区，而超细干粉自动灭火装置只按保护对象计算面积或体积来确定灭火剂的用量，用量大为减少，降低了一次灭火的费用。ntttt

ntttttt一、 超细干粉灌装机概述 nttttt
nttttt
ntttttt超细干粉灌装机是我厂参照国内外粉类灌装机的优点结合实际灌装的特点，开发、设计的新型产品，采用了真空射流技术，将干粉快速吸入被装筒体，配备高精度的称重显示仪。使其灌装具备了自动化、计量化。同时利用真空所产生的负压，对过滤器上的残余粉尘进行清除。本机集电子、电器、机械于一体，从而减轻了劳动强度，改善了工作环境，具有体积小、重量轻、能耗低、外形美观、移动方便、操作简单、使用寿命长等特点，特别适用于干粉灭火器的粉灌装、回收，也是其它粉类灌装行业的理想设备。nttttt

ntttttt三、 超细干粉灌装机用途及使用 nttttt
nttttt
ntttttt用途： nttttt
nttttt
ntttttt干粉灌装机选用了0.55千瓦、电机作为动力，真空泵实现抽真空，它既能满足各种粉灭火器的灌装，又能把旧灭火器筒内的干粉吸出，非常适合生产厂家连续灌装和维修厂家操作灌装两种灌装方式。nttttt
nttttt
ntttttt本机灌装过程中，粉由吸粉管经灌装端盖，灌入筒体，当旧灭火器筒内的粉需吸出时，应把吸粉管放入旧灭火器筒内，将旧干粉被吸出。(对旧灭火器内已失效的干粉不能吸出)nttttt
nttttt
ntttttt操作使用： nttttt
nttttt
ntttttt1、连接管路nttttt
nttttt
ntttttt首先将本机吸粉管与仓库的圆锥型储粉桶连接好，(储粉桶锥度一般为3：2，用户可根据生产量自定储粉桶的大小)再检查各连接管是否有松动。nttttt
nttttt
ntttttt2、保护装置nttttt
nttttt
ntttttt连接好干粉机的保护接线。称台接地线是为了消除静电而设置的。由于干粉灌装过程中产生静电，且对称台传感器及显示仪干扰，所以必须接地。nttttt
nttttt
ntttttt3、去皮nttttt
nttttt
ntttttt将被装筒体放在电子称台上，放好灌装端盖(，当显示仪【稳定Ο】指示灯亮时，按【置零】键或【去皮】键，显示仪显示“0.000”，则完成去皮。nttttt
nttttt
ntttttt4、操作灌装nttttt
nttttt
ntttttt操作灌装时，将蝶阀3关闭，铜球阀2打开，把钮子开关扭至【灌装】位置，按【真空运行】按钮，真空泵开始工作。然后按【灌装启动】按钮，粉通过吸粉管吸入被装筒体内，当灌装到设定重量值时，灌装自动停止。每灌装一具需按一次【灌装启动】按钮。如在灌装过程中需要中断灌装，只要按【灌装停止】按钮即可；若要真空泵停机，按【真空停止】按钮即可。nttttt
nttttt
ntttttt四、 超细干粉灌装机清除过滤器粉尘 nttttt
nttttt
ntttttt在正常工作时，每装完一具筒体，本机对过滤器自动清除一次。由于干粉具有很强的依附力，所以当需要彻底清除过滤器的残留粉尘时，将蝶阀打开，把钮子开关扭至【清洗】位置，将铜球阀2关闭，此时，只要不按【真空停止】按钮，真空泵仍继续工作，电磁阀在控制器的作用下，通过各电磁阀之间的相互配合，对过滤器总成反复抽气、补气。利用负压所产生的空气压力，使过滤器得以清除。清除工作结束后，如果需要将粉尘落入残余粉桶内，将蝶阀3打开，残余粉落入残粉筒内，如果要继续灌装，将铜球阀2打开，蝶阀3关闭，把钮子开关扭至【灌装】位置，【灌装启动】打开，则又进入到灌装状态。nttttt
