Now many businesses will use the electric rolling shutter door, which is because it has the characteristics of convenient switching and safety, so it is very popular with people. What characteristics should a good electric rolling shutter door meet? Let Jinan rolling shutter door manufacturer introduce it to you:

1.從材質的選用上來說：簾面它采用無機耐火布、硅酸鋁纖維毯、防輻射布和裝飾布經高溫線縫制而成，雙面用鍍鋅鋼制條夾制，確保簾布的抗風強度，底梁為鋼質鍍鋅，厚度1.2㎜，無接縫; 卷軸：焊接鋼管，規格165厚度2.0mm，管壁外需除銹防腐; 導軌：鋼質鍍鋅板厚度1.2mm，采用分體復合制作。導軌的滑動面應光滑平直，直線度每米不得大于1.5mm，全長直線不得超過0.12%。導軌的頂部應成圓弧形，其長度應超過洞口少75mm具有防煙性能的導軌必須有防煙裝置，使用材料應為不燃材料隔煙裝置與卷簾表面應均勻緊密貼合，貼合面不應小于80%;特級防火卷簾門座板與地面間隙不宜大于20mm。：

1. In terms of material selection: the curtain surface is made of inorganic refractory cloth, aluminum silicate fiber blanket, radiation proof cloth and decorative cloth by high-temperature suture, and the double sides are clamped with galvanized steel strip to ensure the wind resistance of the cord fabric. The bottom beam is made of steel galvanized steel with a thickness of 1.2 mm and no joint; the reel: welded steel pipe, with a specification of 165 and a thickness of 2.0 mm, needs rust removal and anti-corrosion outside the pipe wall; Guide rail: the thickness of steel galvanized sheet is 1.2mm, which is made of split composite. The sliding surface of the guide rail shall be smooth and straight, the straightness shall not be greater than 1.5mm per meter, and the straight line of the whole length shall not exceed 0.12%. The top of the guide rail shall be in arc shape, and its length shall be at least 75mm beyond the hole opening. The guide rail with smoke prevention performance must be equipped with smoke prevention device, and the material used shall be non combustible material. The smoke isolation device and the rolling shutter surface shall be evenly and tightly fitted, and the joint surface shall not be less than 80%; the gap between the door seat plate of the super fire shutter and the ground shall not be greater than 20 mm. :

2.控制系統的功能： 卷簾可獨立控制并具有手動功能，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，卷簾自動下降地面1.5-1.8m高度，延時180秒(可調)然后在下降關閉。當下降時遇到障礙物可停止下降并上升; 可實現煙感報警一次下滑，溫感報警二次下滑，且溫感報警后可停止二次下滑，可在一個系統內互相轉換。符合標準6.4.6的要求; 垂直啟閉速度：不小于2m/min。其自重下降速度不應大于9.5m/s，平均噪音85dB。

2. Function of control system: the rolling shutter can be controlled independently and has manual function, linked with temperature fuse device and directly linked with central fire control room; smoke alarm is realized; the rolling shutter automatically drops to the height of 1.5-1.8m on the ground, with a delay of 180 seconds (adjustable) and then closed after descending. When falling, it can stop falling and rising when encountering obstacles; it can realize the smoke alarm for one time and the temperature sensor for the second time, and after the temperature sensor alarm is eliminated, it can stop the second sliding, which can be converted to each other in a system. Meet the requirements of standard 6.4.6; vertical opening and closing speed: not less than 2m / min. The self weight drop speed should not be greater than 9.5m/s and the average noise is 85dB.

3.電氣功能：主電源50HZ，380V，信號電源24V，功率 0.37-2.2KW(根據門洞大小確定電機功率);特級防火卷簾門應設有手動啟閉裝置，以備斷電時使用; 應具有依靠卷簾自重下降的性能，并具有恒速性能，手動速放裝置的操作力不得大于50N;卷簾門它應使用消防電源，電源線應穿金屬管暗敷，明敷時應采取防火保護措施;無火警時，卷簾具備上、停、下等手動和電動基本功能，上、下限位準確可靠。

3. Electrical function: main power supply is 50 Hz, 380 V, signal power supply is 24 V, power is 0.37-2.2kw (motor power is determined according to the size of the door opening); the super fire shutter door shall be equipped with manual opening and closing device for use in case of power failure; it shall have the performance of relying on the self weight of rolling shutter and have constant speed performance; the operation force of manual quick release device shall not be greater than 50N; The rolling shutter door should use fire-fighting power supply. The power line should be concealed through metal tube, and fire protection measures should be taken when there is no fire. When there is no fire alarm, the rolling shutter has the basic manual and electric functions of up, down and down, and the upper and lower limits are accurate and reliable.

4.結構部件的選用：卷管為優良鋁合金材料，強度高，且不易變形;表面進行陽極氧化處理，防老化、耐腐蝕。安裝支架選用高強度合金鋼，抗彎、抗剪強度大，保證機構安裝使用的可靠性。

4. Selection of structural components: the coiled tube is made of excellent aluminum alloy material with high strength and is not easy to deform; the surface is anodized to prevent aging and corrosion. High strength alloy steel is selected for the mounting bracket, which has high bending and shear strength, ensuring the safety and reliability of the installation and use of the mechanism.
