  卷簾門可獨立控製並具有手動功能,與溫度熔斷裝置聯動,與消防中控室直接進行聯動;實現煙感報警,卷簾門自動下降至地麵1.5-1.8m高度,延時180秒(可調)然後在下降關閉。
  The rolling shutter door can be controlled independently and has manual function. It is linked with the temperature fuse device and directly linked with the fire control center control room. It can realize smoke sensing alarm and the rolling shutter door will automatically descend to the ground One point five - 1.8m Altitude, delay 180 seconds (adjustable) and then close in descent.
  當下降時遇到障礙物可停止下降並上升; 可實現煙感報警一次下滑,溫感報警二次下滑,且溫感報警消除後可停止二次下滑,可在一個係統內互相轉換。符合標準6.4.6的要求; 垂直啟閉速度:不小於2m/min。其自重下降速度不應大於9.5m/s,平均噪音85dB。
  In case of falling, it can stop falling and rising when encountering obstacles; it can realize one-time sliding of smoke alarm and two-time sliding of temperature alarm, and it can stop the two-time sliding after the temperature alarm is eliminated, which can be converted to each other in a system. Compliance with standards 6.4.6 Vertical opening and closing speed: not less than 2m / min. Its self weight falling speed shall not be greater than 9.5m/s The average noise is 85dB.

  不鏽鋼件它在安裝焊接前,必須認真的清理其表麵的油汙、灰塵等雜物。焊接時它應盡量采用氬弧焊。如果采用手工電弧焊時,應用小電流焊,嚴禁在非焊區引弧。所用地線它應選擇適當位置,連接牢固,以免電弧燒傷表麵或燒傷麵積過大;焊接時它應采取防飛濺措施。
  Before the installation and welding of stainless steel parts, the oil dirt, dust and other sundries on the surface must be carefully cleaned. Argon arc welding shall be used as far as possible during welding. If manual arc welding is adopted, small current welding shall be applied, and arc striking in non welding area is strictly prohibited. The ground wire used shall be in a proper position and connected firmly to avoid arc burn on the surface or excessive burn area; during welding, it shall take measures to prevent splashing.
  濟南卷簾門廠家提醒您:焊接後清理焊渣時應用不鏽鋼扁鏟,不得用碳鋼類扁鏟。焊縫處它應認真修磨,使焊縫與母材表麵光滑過渡,不得有熔渣、氣孔、咬邊、飛濺物、裂紋、未熔合等質量缺陷。
  Jinan roller shutter door manufacturer reminds you: after welding, when cleaning welding slag, stainless steel flat shovel shall be used instead of carbon steel flat shovel. The weld joint shall be carefully polished to make the smooth transition between the weld joint and the base metal surface, and there shall be no slag, air hole, undercut, spatter, crack, incomplete fusion and other quality defects.
