快速卷帘门是现代工业建筑中常用的一种装饰门。具体来说，快速卷帘门是快速升降的无障碍隔离门；它具有普通装饰门所不具备的功能，主要包括保温、保湿、防尘、防虫、隔音等，使车间保持恒温、恒湿、清洁的工作环境。

Quick rolling shutter door is a commonly used decorative door in modern industrial buildings. Specifically, fast rolling shutter doors are barrier free isolation doors that can be quickly lifted and lowered; It has functions that ordinary decorative doors do not have, mainly including insulation, moisture retention, dust prevention, insect prevention, sound insulation, etc., to maintain a constant temperature, humidity, and clean working environment in the workshop.

组成结构：快速卷帘门的功能由其不同组件的功能决定。目前，市场上快速卷帘门的组成部分主要由门框自动控制设备组成，PVC由门帘、驱动电机、控制系统等组成。各部分使用的材料不同，其功能也不同。

Composition: The function of the quick rolling shutter door is determined by the functions of its different components. At present, the components of fast rolling shutter doors on the market are mainly composed of door frame automatic control equipment, while PVC is composed of door curtains, driving motors, control systems, etc. The materials used in each part are different, and their functions are also different.

驱动电机：快速卷门采用制动减速电机，制动速度快，噪音低。

Drive motor: The fast rolling door adopts a braking deceleration motor, which has fast braking speed and low noise.

随着工业经济的快速发展，对大型快速卷帘门的需求越来越大，广泛应用于各种工业厂房、物流通道、车间、仓库、机房、车库等场所。

With the rapid development of the industrial economy, there is an increasing demand for large and fast rolling shutter doors, which are widely used in various industrial factories, logistics channels, workshops, warehouses, machine rooms, garages and other places.

同时，随着工业门系列产品的改进，对门体外观、抗风强度、驱动控制系统、制造工艺和使用寿命的合理性要求越来越高。据了解，工业门设计新一代产品是为了满足这个市场的要求。

Meanwhile, with the improvement of industrial door series products, the requirements for the rationality of door appearance, wind resistance, drive control system, manufacturing process, and service life are becoming increasingly high. It is understood that the design of the new generation of industrial doors is to meet the requirements of this market.

快速卷帘门不能关闭的原因：

The reason why the fast rolling shutter door cannot be closed is:

检查地面传感器控制器：如果地面传感器控制器的绿灯长时间亮，此时无法操作手动开关；按住地面传感器上的复位键超过5秒。松开后，红灯长时间亮起，绿灯熄灭；如果复位后绿灯仍然亮着，请检查地面传感器线圈周围是否有相应体积的铁；

Check the ground sensor controller: If the green light of the ground sensor controller is on for a long time, the manual switch cannot be operated at this time; Press and hold the reset button on the ground sensor for more than 5 seconds. After releasing, the red light stays on for a long time and the green light goes out; If the green light is still on after resetting, please check if there is a corresponding volume of iron around the ground sensor coil;

在自动状态下，超过设定的延迟关闭时间，门体仍未下降，检查红外指示灯是红色还是绿色，绿色正常，红色表示故障，适当调整红外位置，直绿灯亮；

In automatic mode, if the door body still does not descend after the set delay closing time, check whether the infrared indicator light is red or green, green is normal, and red indicates a fault. Adjust the infrared position appropriately until the green light is on;

门体卡滞或门体吊带脱落。

The door body is stuck or the door lifting strap is detached.

门体重复运行：当门体重复运行时，检查门体下降过程中是否有物体或窗帘本身切断红外线，并采取相应措施排除。

Repeated operation of the door body: When the door body is running repeatedly, first check if there are any objects or curtains that cut off infrared radiation during the descent process of the door body, and take corresponding measures to eliminate it.
