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.从材质的选用上来说：帘面它采用无机耐火布、硅酸铝纤维毯、防辐射布和装饰布经高温线缝制而成，双面用镀锌钢制条夹制，确保帘布的抗风强度，底梁为钢质镀锌，厚度1.2㎜，无接缝； 卷轴：焊接钢管，规格165厚度2.0mm，管壁外需除锈防腐； 导轨：钢质镀锌板厚度1.2mm，采用分体复合制作。导轨的滑动面应光滑平直，直线度每米不得大于1.5mm，全长直线不得超过0.12%。导轨的顶部应成圆弧形，其长度应超过洞口至少75mm具有防烟性能的导轨必须有防烟装置，使用材料应为不燃材料隔烟装置与卷帘表面应均匀紧密贴合，贴合面不应小于80%；特级防火卷帘门座板与地面间隙不宜大于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.控制系统的功能： 卷帘可独立控制并具有手动功能，与温度熔断装置联动，与消防中控室直接进行联动；实现烟感报警，卷帘自动下降至地面1.5-1.8m高度，延时180秒（可调）然后在下降关闭。当下降时遇到障碍物可停止下降并上升； 可实现烟感报警一次下滑，温感报警二次下滑，且温感报警消除后可停止二次下滑，可在一个系统内互相转换。符合标准6.4.6的要求； 垂直启闭速度：不小于2m/min。其自重下降速度不应大于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.电气功能：主电源50HZ，380V，信号电源24V，功率 0.37-2.2KW（根据门洞大小确定电机功率）；特级防火卷帘门应设有手动启闭装置，以备断电时使用； 应具有依靠卷帘自重下降的性能，并具有恒速性能，手动速放装置的操作力不得大于50N；卷帘门它应使用消防电源，电源线应穿金属管暗敷，明敷时应采取防火保护措施；无火警时，卷帘具备上、停、下等手动和电动基本功能，上、下限位准确可靠。
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.
