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.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. 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. 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.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 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.结构部件的选用：卷管为优良铝合金材料，强度高，且不易变形;表面进行阳极氧化处理，防老化、耐腐蚀。安装支架选用高强度合金钢，抗弯、抗剪强度大，保证机构安装使用的可靠性。

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.
