電動煙幕豎墻的工作原理
可按一臺或多臺制造安裝，控制機構安裝在墻上或圓筒上。當發生火災時，控制中心輸出信號啟動電機或執行器，防煙垂直墻開始工作(也可通過手動按鈕或煙霧傳感器控制)，形成高度為500 mm至800 mm的防煙垂直墻，各單元上升直至恢復原位。還可以通過展開和收回相關設備的聯動實現自動控制。
電氣防煙垂直墻防火布的分類:
防火布的種類很多，不同的材料可以加工成不同的防護布，一般分為:普通防火涂膠玻璃纖維布、石棉防火布、硅橡膠涂膠玻璃纖維布、藍色玻璃纖維防火布、陶瓷纖維涂膠防火布、高二氧化硅防火布、鋁箔防火布、陶瓷纖維防火布等。
電動防煙壁掛是一種智能化的電氣化產品，由程序控制。每季度需要對其功能進行測試，并對電路進行檢查和維護。如果發生火災，無法自動控制，需要手動控制防煙掛壁。
電動煙幕的垂壁性能:
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.
