防火卷帘门是适合建筑物大开口的防火、隔热设施，是产品在设计安装中发挥一定作用的技术。防火快门广泛应用于工业和民用建筑的防火隔墙地区，是有效防止火势蔓延、保障生命财产的现代建筑不可缺少的防火设施。

　　Fireproof rolling shutter door is a fireproof and thermal insulation facility suitable for large openings in buildings, and is a technology that plays a certain role in the design and installation of products. Fireproof shutter is widely used in fire-resistant partition areas of industrial and civil buildings, and is an indispensable fire prevention facility in modern buildings that effectively prevents the spread of fire and ensures the safety of life and property.

　　防火卷帘门的作用是什么？

　　What is the function of fireproof rolling shutter doors?

　　防火快门像防火墙一样进行水平防火区分。包括窗帘、座椅、导轨、支撑、卷轴、盒子、控制箱、快门、限制器、门楣、手动速度开关装置、按钮开关、保险装置等13个部分，通常安装在不被防火墙分隔的部分。比如：电梯大厅、扶梯、百货商店宽敞的营业所、展示厅的展厅、建筑物的洞口大的话，防火门和窗户不能使用的部位。防火卷帘机在建筑工程中广泛应用了防火分离。

　　Fireproof shutter functions like a firewall for horizontal fire separation. It includes 13 parts such as curtains, seats, rails, supports, scrolls, boxes, control boxes, shutters, limiters, door lintels, manual speed switch devices, button switches, safety devices, etc. It is usually installed in parts that are not separated by firewalls. For example, elevator lobbies, escalators, spacious department store offices, exhibition halls, and areas where fire doors and windows cannot be used due to large openings in buildings. Fireproof rolling shutter machines are widely used in building engineering for fire separation.

　　防火卷帘门是现代高层建筑中不可缺少的防火设施，防火门除了起到普通门的作用外，还具有防火、防烟、压制火灾扩散、保护人员疏散的特殊功能，广泛适用于高层建筑、大型等人员密集的情况。

　　Fireproof rolling shutter doors are indispensable fire prevention facilities in modern high-rise buildings. In addition to serving as ordinary doors, fireproof doors also have special functions such as fire prevention, smoke prevention, suppression of fire spread, and protection of personnel evacuation. They are widely used in densely populated situations such as high-rise buildings and large shopping malls.

　　防火卷帘门以钢质卷帘机为基础，对传动部件进行改造，配备防火电气等设备，实现防火作用。防火电机由防火灯箱控制，通过变速装置驱动卷盘，使快门关闭，停电时也可以使用防火电机的手摇进行手动操作。在机械相对运动中，用联轴器代替链轮传动，并在钢轨内部摩擦上钉上铜板或尼龙。适合有易燃气体、易挥发化学药品等高发性物品的工厂和仓库等可能出现或爆炸的火灾危险的环境。

　　The fireproof rolling shutter door is based on a steel rolling shutter machine, with modifications made to the transmission components and equipped with fire-resistant electrical equipment to achieve fire prevention. The fireproof motor is controlled by a fireproof light box and drives the spool through a variable speed device to close the shutter. It can also be manually operated by hand during power outages. In mechanical relative motion, a coupling is used instead of a sprocket for transmission, and copper plates or nylon are frictionally nailed to the inside of the steel rail. Suitable for environments such as factories and warehouses with high risk of fire hazards such as flammable gases and volatile chemicals that may cause explosions.

　　1、内部集成总线，数据传输可靠，速度快。

　　1. Internally integrated bus, reliable data transmission, fast speed.

　　2、相位顺序自动检测、校正和相位保护功能不足。主电源SPs提供自动切换功能(包括备份)。

　　2. The automatic detection, correction, and phase protection functions for phase sequence are insufficient. The main power SPs provide automatic switching function (including backup).

　　3、有丰富的预约界面，可以与消防控制中心联系。

　　3. There is a rich appointment interface where you can contact the fire control center.

　　4、全电子学习内存限度，无论上限还是下限都不变。

　　4. The memory limit for fully electronic learning remains unchanged, regardless of the upper or lower limit.

　　5.采用微机处理器技术，稳定可靠，没有上限海拔范围限制。

　　5. Adopting advanced microcomputer processor technology, stable and reliable, without upper limit altitude range restrictions.

　　6、烟雾、温度检测信号同步，阶段性检测功能。

　　6. Synchronization of smoke and temperature detection signals, with phased detection function.

　　7、操作参数设置，简单、方便、准确。

　　7. Operating parameter settings are simple, convenient, and accurate.

　　8、有手动优先逃生功能。三相电或主电出现故障时，控制器可以通过速防装置自动掉下窗帘，从而实现关闭窗帘的功能。

　　8. There is a manual priority escape function. When there is a malfunction in the three-phase or main power supply, the controller can automatically lower the curtains through a speed protection device, thereby achieving the function of closing the curtains.

　　在运营运用过程中，运营商不能私下分离地址，要密切注意开闭状态和执行情况，开闭时禁止站在窗帘下行走。在运用过程中，如果发现异常情况，应立即接受重要方法，切断输入电源，缺点。防火卷帘机要按期制定保护规范，做好各窗帘的保护记录任务，立案保管。长时间未合上的窗帘半年要保护一次，内容相当于除尘、喷漆、传动部链轮滚子链上光滑的油生。

　　In the process of operation and use, operators cannot privately separate addresses and should closely monitor the opening and closing status and execution. It is forbidden to stand under the curtains and walk during opening and closing. In the process of application, if any abnormal situation is found, important methods should be immediately adopted to cut off the input power and eliminate the shortcomings. The fireproof rolling shutter machine should establish protection standards on schedule, keep records of the protection of each curtain, and file for safekeeping. Curtains that have not been closed for a long time should be protected every six months, which is equivalent to dust removal, painting, and smooth oil production on the sprocket roller chain of the transmission part.
