电动烟幕竖墙的工作原理
可按一台或多台制造安装，控制机构安装在墙上或圆筒上。当发生火灾时，控制中心输出信号启动电机或执行器，防烟垂直墙开始工作(也可通过手动按钮或烟雾传感器控制)，形成高度为500 mm至800 mm的防烟垂直墙，各单元上升直至恢复原位。还可以通过展开和收回相关设备的联动实现自动控制。
电气防烟垂直墙防火布的分类:
防火布的种类很多，不同的材料可以加工成不同的防护布，一般分为:普通防火涂胶玻璃纤维布、石棉防火布、硅橡胶涂胶玻璃纤维布、蓝色玻璃纤维防火布、陶瓷纤维涂胶防火布、高二氧化硅防火布、铝箔防火布、陶瓷纤维防火布等。
电动防烟壁挂是一种智能化的电气化产品，由程序控制。每季度需要对其功能进行测试，并对电路进行检查和维护。如果发生火灾，无法自动控制，需要手动控制防烟挂壁。
电动烟幕的垂壁性能:
1. The running speed of electric or mechanical descent of the vertical wall of the rolling shutter smoke screen shall be ≥ 0.07m/s.. The running time of electric or mechanical descent of the flap-type smoke-proof vertical wall should be less than ＜7s；;
2, smoke vertical wall should be equipped with limit device, when it runs to the upper and lower limit, it can automatically stop. Reliability of electric smoke screen hanging wall;
3. After 1000 opening and closing operations, the smoke screen vertical wall should be able to operate normally. A probe with a diameter of (6 0.1) mm or a test block with a length of (15±0.1)mm and a width of (24±0.1)mm cannot pass through the smoke blocking part of the smoke blocking vertical wall;
4. When the smoke-proof vertical wall bears the wind speed of (5 1) m/s, its vertical deflection angle should be no greater than 15;
5, smoke vertical wall at (620 20)℃ for 30min, its integrity should not be destroyed.
