电动卷帘门“三分产品，七分保养”。一扇保养得当的卷帘门，使用寿命可达10年以上；而从不保养的卷帘门，3年左右就开始频繁出故障——卡顿、异响、电机烧坏。以下保养要点，建议按月、按季度、按年三级执行。

Electric rolling shutter doors are three parts product and seven parts maintenance. A properly maintained rolling shutter door can have a service life of over 10 years; And the rolling shutter door that is not maintained starts to frequently malfunction after about 3 years - lagging, abnormal noise, and motor burnout. The following maintenance points are recommended to be carried out at three levels: monthly, quarterly, and yearly.

电动卷帘门常见故障类型

Common fault types of electric rolling shutter doors

根据维修统计，卷帘门损坏主要集中在三类：

According to maintenance statistics, the damage to rolling shutter doors is mainly concentrated in three categories:

导轨摩擦条磨损：导轨内部的摩擦条是消耗品，长期推拉后损耗，导致帘板直接与导轨接触，门推不动。直接更换摩擦条即可。

Wear of guide rail friction strip: The friction strip inside the guide rail is a consumable, which is worn out after long-term pushing and pulling, causing the curtain plate to directly contact the guide rail and the door to not move. Simply replace the friction strip.

卷轴弹簧片断裂：高档卷帘门内部有弹簧片，作用是防止门在关闭时弹起、在打开时下落。弹簧片断裂后，门会出现“开启时自动下落、下落时又自动弹起”的故障。

Broken scroll spring plate: There are spring plates inside the high-end rolling shutter door, which prevent the door from bouncing up when closed and falling down when opened. After the spring plate breaks, the door will experience a fault of "automatically falling when opened and automatically popping up when dropped".

帘板固定件松动：固定条磨损、铆钉脱落后，帘板变形、扭曲，导致门无法正常使用。

Loose fixing parts of the curtain panel: After the fixing strip wears out and the rivets fall off, the curtain panel deforms and twists, causing the door to be unable to function properly.

每月检查（基础养护）

Monthly inspection (basic maintenance)

轨道清灰：及时清理轨道内的杂物、沙尘，防止卡阻。这是非常简单但非常容易被忽略的保养项。

Track cleaning: Timely clean the debris and dust inside the track to prevent jamming. This is the simplest but most easily overlooked maintenance item.

异常声音监测：运行时有无异常摩擦声或尖锐声响。发现异响应立即停止，检查排除杂物后再运行。

Abnormal sound monitoring: Check for abnormal friction or sharp sounds during operation. Stop immediately if abnormal response is found, check and eliminate debris before running again.

密封条检查：底部橡胶密封条是否完好，有无破损或脱落。

Sealing strip inspection: Check if the bottom rubber sealing strip is intact, whether it is damaged or detached.

每季度保养（关键养护）

Quarterly maintenance (key maintenance)

链条/链轮润滑：每3-6个月给链条、链轮加注专用润滑油，切忌使用粘稠的废机油——废机油会加速灰尘附着，反而加剧磨损。卷帘门电机和传动链条需经常加注润滑剂。

Chain/sprocket lubrication: Add specialized lubricating oil to the chain and sprocket every 3-6 months, and avoid using viscous waste engine oil - waste engine oil can accelerate dust adhesion and exacerbate wear. The motor and transmission chain of the rolling shutter door need to be regularly lubricated.

控制器清洁：检查控制箱内器件和开关控制盒，紧固接线端口，清洁控制箱内和按钮上的灰尘，防止按钮卡住而不能反弹。

Controller cleaning: Check the components and switch control boxes inside the control box, tighten the wiring ports, clean the dust inside the control box and on the buttons to prevent the buttons from getting stuck and unable to bounce back.

螺丝紧固检查：固定螺丝定期检查紧固，防止因震动松动导致门体脱轨、扭簧变形。

Screw tightening inspection: Regularly check the fastening of fixed screws to prevent door derailment and torsion spring deformation caused by vibration loosening.

年度专业检查（深度养护）

Annual professional inspection (deep maintenance)

扭簧防锈与平衡测试：检查扭簧表面防锈情况；测试门体能否在任意位置悬停——如果门体不能悬停，说明扭簧平衡需要重新调整。

Anti rust and balance test of torsion spring: check the anti rust condition of the surface of the torsion spring; Test whether the door can hover at any position - if the door cannot hover, it indicates that the balance of the torsion spring needs to be readjusted.

安全功能测试：测试遇阻反弹功能是否正常、红外感应是否灵敏、手动启闭力是否≤260N。

Safety function test: Test whether the rebound function is normal when encountering obstacles, whether the infrared sensing is sensitive, and whether the manual opening and closing force is ≤ 260N.

电机与控制系统检查：检查电机运行状态，做一次多维度的电气安全检查——老旧线路改造的门店务必核对电源电压与负载匹配。

Motor and control system inspection: Check the operation status of the motor and conduct a comprehensive electrical safety inspection - stores that have renovated old lines must verify that the power supply voltage matches the load.

刹车与限位检查：卷帘门在开关停止过程中，应具有随位停止功能，不应停止后继续下降。如下降距离大于50mm，应立即检查卷帘门控制器和制动器。

Brake and limit check: The rolling shutter door should have a stop function during the opening and closing process, and should not continue to descend after stopping. If the descent distance is greater than 50mm, the rolling shutter door controller and brake should be checked immediately.
