常见故障解析

Common fault analysis

1、门体无法正常升降：这是卷帘门常见的问题之一。可能原因包括电机故障，比如电机过热烧毁、内部零件磨损等；传动系统出现问题，如链条脱落、齿轮损坏；电源问题，像插头松动、线路短路或断路等。

1. The door cannot be raised or lowered properly: This is one of the most common problems with rolling shutter doors. Possible reasons include motor malfunctions, such as overheating and burning of the motor, wear and tear of internal components, etc; There are problems with the transmission system, such as chain detachment and gear damage; Power issues, such as loose plugs, short circuits or open circuits in the wiring.

2、关闭不严：卷帘门关闭时存在缝隙，可能是门体变形，这通常是由于受到外力撞击或长期使用导致的；轨道内有异物阻挡，影响门体下滑；安装不当，使门体与轨道不匹配。

2. Poor closure: There are gaps when the rolling shutter door is closed, which may be caused by deformation of the door body, usually due to external impact or long-term use; There are foreign objects blocking the track, which affects the sliding of the door body; Improper installation causes the door body to not match the track.

3、自动控制失灵：卷帘门配备的自动感应或遥控装置失效。原因可能是传感器故障，如灰尘积累影响感应效果，或者传感器本身损坏；控制器出现问题，如芯片故障、按键失灵；遥控器电池电量不足，或者遥控器与接收器之间的信号传输受阻。

3. Automatic control failure: The automatic sensing or remote control device equipped with the rolling shutter door fails. The reason may be sensor malfunction, such as dust accumulation affecting the sensing effect, or damage to the sensor itself; Controller issues, such as chip failure or button malfunction; The remote control battery is low, or the signal transmission between the remote control and the receiver is obstructed.

4、异常噪音：卷帘门在升降过程中发出刺耳噪音，可能是卷轴、链条、齿轮等部件缺乏润滑，摩擦增大；部件松动，如螺丝、螺母松动，导致运转时产生震动；电机轴承磨损，影响电机正常运转。

4. Abnormal noise: The rolling shutter door makes a piercing noise during the lifting process, which may be due to a lack of lubrication in components such as the scroll, chain, and gears, resulting in increased friction; Loose components, such as screws and nuts, can cause vibration during operation; The wear of motor bearings affects the normal operation of the motor.

维修方法介绍

Introduction to Maintenance Methods

1、门体无法正常升降维修：先检查电源，确保插头插紧，用万用表检测线路是否通电。若电源正常，查看电机外观有无烧焦痕迹，如有则需更换电机。对于传动系统，重新安装脱落的链条，更换损坏的齿轮。

1. Door body cannot be lifted and lowered properly for maintenance: First, check the power supply to ensure the plug is securely plugged in, and use a multimeter to check if the circuit is powered on. If the power supply is normal, check the appearance of the motor for burnt marks. If there are, replace the motor. For the transmission system, reinstall the detached chain and replace the damaged gear.

2、关闭不严维修：清理轨道内的杂物，用刷子和清洁剂去除污垢。对于变形门体，轻微变形可尝试手动校正，严重变形则需更换门体。检查安装情况，重新调整门体与轨道的位置，确保安装牢固且对齐。

2. Loosening maintenance: Clean the debris inside the track and use a brush and cleaning agent to remove dirt. For deformed door bodies, slight deformation can be manually corrected, while severe deformation requires replacement of the door body. Check the installation situation, readjust the position of the door body and track, and ensure that the installation is firm and aligned.

3、自动控制失灵维修：清洁传感器表面灰尘，若仍无反应则更换传感器。检查控制器线路连接是否松动，尝试重启控制器，若问题未解决，更换控制器。遥控器先更换电池，若无效，检查遥控器与接收器的配对情况，必要时重新配对。

3. Automatic control malfunction repair: Clean the dust on the surface of the sensor. If there is still no response, replace the sensor. Check if the controller circuit connection is loose, try restarting the controller, and if the problem persists, replace the controller. Replace the battery of the remote control first. If it doesn't work, check the pairing between the remote control and the receiver, and re pair if necessary.

4、异常噪音维修：对卷轴、链条、齿轮等部件涂抹润滑油，确保润滑充分。紧固松动的螺丝、螺母，部件震动。若电机轴承磨损，需人员更换轴承。

4. Abnormal noise maintenance: Apply lubricating oil to components such as scrolls, chains, gears, etc. to ensure adequate lubrication. Tighten loose screws and nuts to eliminate component vibration. If the motor bearings are worn, professional personnel need to replace the bearings.
