Most facades will choose electric curtain, why? It has what advantages, easy to use, safe and secure, is the main reason for the merchants to choose electric roll curtain. What are the requirements of a high-quality electric rolling shutter door?
1.從材質的選用上來說：簾麵它采用無機耐火布、矽酸鋁纖維毯、防輻射布和裝飾布經高溫線縫製而成，雙麵用鍍鋅鋼製條夾製，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，管壁外需除鏽防腐； 導軌：鋼質鍍鋅板厚度1.2mm，采用分體複合製作。導軌的滑動麵應光滑平直，直線度每米不得大於1.5mm，全長直線不得超過0.12%。導軌的頂部應成圓弧形，其長度應超過洞口至少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麵應均勻緊密貼合，貼合麵不應小於80%；特級防火卷簾門座板與地麵間隙不宜大於20mm。：
1. From the selection of materials: the curtain is made of inorganic refractory cloth, aluminium silicate fiber blanket, radiation-proof cloth and decorative cloth sewn by high-temperature thread, double-sided with galvanized steel strip clamping, to ensure the wind resistance of the curtain, the bottom beam is galvanized steel, thickness is 1.2 mm, seamless; the coil: welded steel pipe, specification 165 thickness is 2.0 mm, except rust and corrosion; the guide rail: galvanized steel. The thickness of the plate is 1.2 mm, which is made of split composite. The sliding surface of the guide should be smooth and straight, the straightness per meter should not be greater than 1.5 mm, and the whole length of the straight line should not exceed 0.12%. The top of the guide rail should be circular arc, and the length of the guide rail should exceed the opening at least 75 mm. The smoke-proof device must have smoke-proof device. The smoke-proof device and the surface of the curtain should be uniformly and tightly fitted with non-combustible material, and the fitting surface should not be less than 80%. The gap between the door seat plate and the ground of the super-grade fire-proof curtain should not be greater than 20 mm. :
2.控製係統的功能： 卷簾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。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。
2. Functions of the control system: the curtain can be controlled independently and manually, and linked with the temperature fuse device, and directly with the fire control room; the smoke alarm can be realized, and the curtain can automatically drop to 1.5-1.8m height on the ground, with a delay of 180 seconds (adjustable) and then close down. When falling, encountering obstacles can stop falling and rising; smoke alarm can decline once, temperature alarm can decline twice, and temperature alarm can stop the second decline after eliminating, and can be converted into each other in a system. It meets the requirement of standard 6.4.6; Vertical opening and closing speed: not less than 2 m/min. Its weight should not drop faster than 9.5m/s, with an average noise of 85 dB.
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，並具有恒速性能，手動速放裝置的操作力不得大於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 50HZ, 380V, signal power supply 24V, power 0.37-2.2KW (according to the size of the door to determine motor power); super-grade fire-proof shutter door should be equipped with manual opening and closing device for use in case of power failure; it should have the performance of relying on the self-weight of the shutter to decline, and it should have constant speed performance, the operation force of manual speed release device should not exceed 50N; fire-fighting power should be used for the shutter door. The power cord should be covered by metal tube, and fire protection measures should be taken when it is applied openly. When there is no fire alarm, the rolling curtain has the basic functions of upper, stop and lower manual and electric, and the upper and lower limits are accurate and reliable.
4. Selection of structural components: coiled tube is made of high-quality aluminium alloy material, which has high strength and is not easy to deform; surface is treated by anodic oxidation to prevent aging and corrosion. The installation bracket is made of high strength alloy steel with high bending and shear strength to ensure the safety and reliability of the installation and use of the mechanism.
