来源:http://www.jnhsjlm.com 日期:2022-05-13 发布人:guanli
防火卷帘门是现代高层建筑中不可缺少的防火设施,主要用于大型超市(大卖场)、大型商场、大型材料市场、大型展馆、厂房、仓库等有消防要求的公共场所。防火电机由防火电控箱控制,通过变速装置驱动卷轴使卷帘门起闭,停电时也可使用防火电机上的手动摇柄,可实现手动操作。在机械相对运动处,采用联轴器代替链轮传动,道轨内摩擦处镶嵌铜板或尼龙。适合于使用或保管可燃性气体、挥发性化学药品等具有高发火性物品的工厂和仓库等出现或可能出现爆炸的火灾危险的环境。

In case of power failure, the manual handle on the fire-proof motor can also be used to realize manual operation. At the relative movement of machinery, the coupling is used to replace the sprocket drive, and the friction part in the track is inlaid with copper plate or nylon. It is suitable for factories and warehouses that use or store combustible gases, volatile chemicals and other highly flammable substances with explosion or possible fire hazards.
