Jinan rolling shutter door is used in workshops, workshops, storage and other occasions. It has many advantages, such as fast switching speed, thermal insulation and cold prevention, dust and wind prevention, sound insulation and fire prevention, so it is favored by many users. However, due to the fast running speed, it is more necessary to pay attention to safety when switching to avoid various dangers.

快速卷帘门经长期使用后，可能会因为零件老化。系统灵活度等问题，出现各种问题。尤其是问题更是不容忽略的。那快速卷帘门长期使用后需要注意哪些方面的保养呢？

After long-term use, the fast rolling shutter door may be due to the aging of parts. System flexibility and other problems, and various problems appear. In particular, security issues can not be ignored. What aspects of maintenance do you need to pay attention to after long-term use of the fast rolling shutter door?

1、 动力与刹车系统

1. Power and braking system

电机的动力和制动系统是整个快速卷帘门的关键核心部件，它能使快速卷帘门平稳、高速、地运行。如果制动系统有故障，应及时修理或更换。例如，刹车失灵，刹车声音大，刹车后门本体仍在下滑，快速卷帘门启动过程中有卡涩现象。当这些情况发生时，如果门没有及时修理或更换，或不能按照警告内容执行，可能会突然下落，电机或其他部件可能损坏，甚造成 人身伤害。

The power and braking system of the motor is the key core component of the whole fast rolling shutter door. It can make the fast rolling shutter door run smoothly, at high speed and safely. If the braking system is faulty, it shall be repaired or replaced in time. For example, the brake fails, the brake sound is loud, the body of the brake rear door is still sliding, and there is jamming in the starting process of the fast rolling shutter door. If the door is suddenly repaired or other parts cannot be replaced according to the warning, it may cause personal injury or even damage when the door falls suddenly.

2、 快速门装置

2. Fast door safety device

快速卷帘门的系统是除制动系统外的安装保护装置，气动装置安装在门轨左右25 cm以下或底部。当车门关闭时，如果有车辆和行人经过，快速车门将自动停止，然后向上运行，直到完全打开。当光电和气囊发生故障时，应及时修理或更换；若不及时更换，则在下行操作过程中，由于门的高速行驶，容易造成行人和车辆的损伤。

The safety system of the fast rolling shutter door is the installation protection device except the braking system. The pneumatic safety device is installed below 25 cm left and right of the door rail or at the bottom. When the door is closed, if there are vehicles and pedestrians passing by, the fast door will automatically stop and then run upward until it is fully opened. In case of failure of safety photoelectric and airbag, it shall be repaired or replaced in time; If it is not replaced in time, it is easy to cause damage to pedestrians and vehicles due to the high-speed driving of the door during downward operation.

3、控制开关系统

3. Control switch system

控制开关系统由快速门的输出、关闭、信号转换、编程等主要部分组成。它分为集成电路、电路板、控制芯片和单独的电气元件。电子元器件对使用环境有很高的要求。为了保证快速门的效率高、运行，在日常使用过程中应经常维护产品，并在控制系统发生故障时及时更换和修理控制系统。

The control switch system consists of the output, closing, signal conversion, programming and other main parts of the fast door. It is divided into integrated circuit, circuit board, control chip and separate electrical components. Electronic components have high requirements for the use environment. In order to ensure the high efficiency and safe operation of the fast door, the product shall be maintained frequently in the process of daily use, and the control system shall be replaced and repaired in time in case of failure of the control system.

4、其它

4. Others

如钢结构、抗风装置、密封装置、联锁装置、门结构、限位装置、急停装置、压路机、开关装置等都是不可分割的系统。确保所有系统的正常运行和维护是非常重要的。

Such as steel structure, wind resistant device, sealing device, interlocking device, door structure, limit device, emergency stop device, roller, switchgear, etc. are all inseparable systems. It is very important to ensure the normal operation and maintenance of all systems.
