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.

快速卷簾門經長期使用后，可能會因為零件老化。系統靈活度等問題，出現各種問題。尤其是問題更是不容忽略的。那快速卷簾門長期使用后需要注意哪些方面的保養呢？

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、 動力與剎車系統

1. Power and braking system

電機的動力和制動系統是整個快速卷簾門的關鍵核心部件，它能使快速卷簾門平穩、高速、地運行。如果制動系統有故障，應及時修理或更換。例如，剎車失靈，剎車聲音大，剎車后門本體仍在下滑，快速卷簾門啟動過程中有卡澀現象。當這些情況發生時，如果門沒有及時修理或更換，或不能按照警告內容執行，可能會突然下落，電機或其他部件可能損壞，甚造成 人身傷害。

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、 快速門裝置

2. Fast door safety device

快速卷簾門的系統是除制動系統外的安裝保護裝置，氣動裝置安裝在門軌左右25 cm以下或底部。當車門關閉時，如果有車輛和行人經過，快速車門將自動停止，然后向上運行，直到完全打開。當光電和氣囊發生故障時，應及時修理或更換；若不及時更換，則在下行操作過程中，由于門的高速行駛，容易造成行人和車輛的損傷。

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、控制開關系統

3. Control switch system

控制開關系統由快速門的輸出、關閉、信號轉換、編程等主要部分組成。它分為集成電路、電路板、控制芯片和單獨的電氣元件。電子元器件對使用環境有很高的要求。為了保證快速門的效率高、運行，在日常使用過程中應經常維護產品，并在控制系統發生故障時及時更換和修理控制系統。

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

如鋼結構、抗風裝置、密封裝置、聯鎖裝置、門結構、限位裝置、急停裝置、壓路機、開關裝置等都是不可分割的系統。確保所有系統的正常運行和維護是非常重要的。

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.
