为了能让卷帘门充分的发挥优良的性能，厂家提醒用户，在日常中要注意对它的维护检查。下面，我们就跟随厂家一起来了解下防火卷帘门的优良特性与维护检查的相关事项。

In order to make the rolling shutter door give full play to its excellent performance, the manufacturer reminds users to pay attention to its maintenance and inspection in daily life. Next, we will follow the manufacturer to learn about the excellent characteristics of the lower fire shutter door and related matters of maintenance and inspection.

防火卷帘门的优良特性

Excellent characteristics of fireproof rolling shutter door

防火卷帘门的耐火特性：从受火功效具有背火面热辐射强度超过临界热辐射强度规定值或达到帘板面窜火时的数值，用于判定防火卷帘门的耐火特性级别。一般来讲防火卷帘门的耐火性能都能够满足使用的要求。

Fire resistance characteristics of fire-proof rolling shutter door: the fire-proof characteristic level of fire-proof rolling shutter door is determined from the value when the heat radiation intensity of the back fire surface exceeds the specified value of the critical heat radiation intensity or reaches the value when the curtain plate surface is on fire. Generally speaking, the fire resistance performance of the fireproof rolling shutter door can meet the requirements of use.

防火卷帘门的防烟特性：防火卷帘安装在房屋建筑墙体上，应与墙内埋件焊接或预埋螺栓连接，也可用膨胀螺栓安装，但其锚固强度要满足使用的要求。防火卷帘门厂家在制作工艺上将传动构件用以更新改造，配以防火电器设备等设施，进而保持防火功效。防火电机由防火电控箱操纵，根据变速装置驱动卷轴使卷帘门起闭，停电时也可采用防火电机上的手动摇柄，可实现手动操作。在机械相对运动处，采用联轴器代替链轮传动，道轨内摩擦处镶嵌铜板或尼龙。对于可燃性气体、挥发物化学品等有着高发火性物品的工厂和仓库等出现或将会冒出爆燃的火灾事故危险性的环境。

Smoke prevention characteristics of fire shutter door: the fire shutter installed on the building wall shall be welded with embedded parts in the wall or connected with embedded bolts. It can also be installed with expansion bolts, but its anchoring strength shall meet the requirements of use. In the manufacturing process, the manufacturer of the fireproof rolling shutter door will update and transform the transmission components, and provide fire-proof electrical equipment and other facilities, so as to maintain the fire-proof effect. The fire-proof motor is operated by the fire-proof electric control box. The roller shutter door is opened and closed according to the drive of the speed change device. In case of power failure, the manual handle on the fire-proof motor can also be used to realize manual operation. At the relative movement of the machinery, the coupling is used to replace the sprocket drive, and the friction part in the track is inlaid with copper plate or nylon. For the factories and warehouses with high ignition substances such as combustible gases, volatile chemicals, etc., there are or will be deflagration fire accidents.

为了避免出现遇到火灾现场无人操作的情况，济南防火卷帘门厂家在制作产品时会设置控制关门装置，这个装置对人员密集场所更为重要。在日常的使用中，用户要注意对卷帘门的维护检查，以保证它能够正常的运行。

In order to avoid the situation that there is no one to operate at the scene of a fire, Jinan fire shutter manufacturer will set up a control closing device when making products, which is more important for densely populated places. In daily use, users should pay attention to the maintenance and inspection of the rolling shutter door to ensure its normal operation.

防火卷帘门的维护检查：

Maintenance and inspection of fire shutter door:

手控检查：在按钮操作上升(或下降)过程中，操作人员应密切注意卷帘门应上升(或下降)到端部位置时能否自动停止，如果不能，应迅速手动停车，且待限位装置修复(或调整)正常后方可重新操作。

Manual control inspection: during the button operation rising (or falling) process, the operator shall pay close attention to whether the roller shutter door can automatically stop when it should rise (or fall) to the end position. If not, it shall be stopped manually quickly and can be operated again after the limit device is repaired (or adjusted) normally.

自控检查：为了保证卷帘门的正常运行，济南防火卷帘门安装维修厂家会设置好烟感装置，卷帘门一旦接受到烟感信号，自动装置将发出报警信号，同时自动启动卷帘门电控系统两次下滑关闭卷帘门。卷帘门一次下滑离地面1.2米左右停车，延时90秒左右，再自动启动卷帘门。

Automatic control inspection: in order to ensure the normal operation of the rolling shutter door, the Jinan fire shutter door installation and maintenance manufacturer will set up the smoke sensing device. Once the rolling shutter door receives the smoke sensing signal, the automatic device will send an alarm signal, and automatically start the electric control system of the rolling shutter door to slide down and close the rolling shutter door twice. The rolling shutter door slides down to about 1.2 meters above the ground at one time and stops, delaying about 90 seconds, and then automatically starts the rolling shutter door.
