解决常见问题:电动卷帘门维修技巧分享

Electric rolling gate is a common type of gate, and most of the rolling gates have already been automated. During its automated operation, there will always be some small troubles to some extent. If the corresponding maintenance methods are not understood, the electric rolling gate will quickly change from "automatic" to "manual" or even "stationary", and intelligent operation will also become unattainable. Today, the editor will introduce several maintenance methods for electric rolling gates, hoping to help you at a critical moment:

当卷闸门突然停止运作

When the roller shutter suddenly stops operating
 

此时我们先找到卷闸门的电机，用手掌等物感觉它是否温度过高，一般来说许多电动卷闸门的电机都自带一种过热保护的装置，如果长时间地使用电动卷闸门，不停地开开关关、上上下下，那么很有可能导致它在运作中途就由于过热，“歇菜”了。这个时候我们只需要停止操作十余分钟，等到电机的温度降到合适的程度就可以继续让电动卷闸门继续工作啦！

At this point, we first find the motor of the roller shutter and use the palm of our hand or other objects to feel if it is too hot. Generally, many electric roller shutter motors come with an overheating protection device. If we use the electric roller shutter for a long time, constantly opening and closing the switch, up and down, it is likely to cause it to "shut down" due to overheating during operation. At this point, we only need to stop the operation for more than ten minutes, and wait until the temperature of the motor drops to the appropriate level to continue the operation of the electric roller shutter!

但电动卷闸门卡机和停止运作不同，电动卷闸门的卡机现象表示它很有可能已经被损坏了传递链条，因而会听到明显的、刺耳的卡机声音。此时我们可以先尝试给电动卷闸门的链条内添加润滑油，此举行不通再考虑更换链条，如果选择后者，记得要找专业人员来进行相关操作。

But the jamming and stopping operation of the electric rolling gate are different. The jamming phenomenon of the electric rolling gate indicates that it is likely to have been damaged by the transmission chain, and therefore a clear and piercing jamming sound will be heard. At this point, we can first try adding lubricating oil to the chain of the electric roller gate. If this is not feasible, we can consider replacing the chain. If you choose the latter, remember to find professional personnel to carry out the relevant operation.
 

电动卷闸门卷过头

电动卷闸门卷过头的现象很明显是电动卷闸门的行程设置过长，与实际情况不匹配。此时我们还是要先找到电机，在电机附近有一个行程开关，别看它只是一个小小的开关，它与电机齿轮的关系可密切着呢，我们对它进行调节后就能合理地控制卷闸门的高低了。

The phenomenon of the electric rolling gate being excessively rolled is clearly due to the excessively long stroke setting of the electric rolling gate, which does not match the actual situation. At this point, we still need to find the motor first. There is a travel switch near the motor. Although it is just a small switch, it is closely related to the motor gear. After adjusting it, we can reasonably control the height of the roller shutter.
 

电动机不动或者转速慢

The motor does not move or the speed is slow
 

许多人都会发现，电动卷闸门的电动机不动时，往往是重复按下按钮都没有反应，这时我们基本可以进行判断是线路断路或者电机内部某些元件被烧损，此时我们应该尝试更换烧损电机以及更换按钮，或者直接打开机械部分，查看是否有卡阻，如果有卡阻进行卡阻障碍物的清除即可。

Many people will find that when the motor of the electric roller shutter is not moving, it often does not respond by repeatedly pressing the button. At this time, we can basically determine whether the circuit is open or some internal components of the motor are burned. At this time, we should try to replace the burned motor and replace the button, or directly open the mechanical part to check for any blockage. If there is any obstruction, the obstruction can be removed.
