卷帘门容易出故障的位置就是导轨、卷轴、帘板这三项，如果是电动卷帘门，那么卷门机、控制箱等部位也有可能会出现故障，下面说说它的一些故障原因和解决方法。

The places where the Roller shutter is prone to failure are the guide rail, roller and shutter. If it is an electric Roller shutter, the roller, control box and other parts may also fail. Here are some reasons for its failure and solutions.

一、导轨故障

1、 Rail failure

正常来讲，无论是哪一种济南卷帘门，两边的导轨内部都是有一层“磨擦条”存在的，这层摩擦条的作用是避免帘板与导轨摩擦而存在的。当卷帘门无法上拉、下拉时，要检查的就是导轨的摩擦条。

Normally, no matter what kind of Roller shutter door is, there is a layer of "friction strip" inside the guide rails on both sides. This layer of friction strip is used to avoid friction between the shutter and the guide rails. When the Roller shutter cannot be pulled up or down, the first thing to check is the friction strip of the guide rail.

摩擦条属于易消耗品，经常推拉卷帘门会导致摩擦条损耗，如果没有了摩擦条，卷帘门会跟导轨直接接触，就会出现卷帘门无法上拉、下拉的故障。

The friction strip is a consumable. Frequent pushing and pulling of the Roller shutter will lead to the loss of the friction strip. If there is no friction strip, the Roller shutter will directly contact the guide rail, and the Roller shutter will fail to pull up and down.

遇到这种情况，直接去购买摩擦条更换即可，如果自己不会更换，可以给安装厂家打电话，让其帮忙售后。

In this situation, you can directly purchase a replacement friction strip. If you don't know how to replace it yourself, you can call the installation manufacturer and ask them to help with after-sales service.

二、卷轴故障

2、 Reel malfunction

卷轴除了负责将帘板卷起之外，它才存在一个隐性的拉力，有一些高档的卷帘门内部会有一个弹簧片存在，主要作用是对帘板施加一个力，禁止卷帘门在关闭的时候弹起，在打开的时候下落。

In addition to being responsible for rolling up the shutter, the roller has a hidden tension. There will be a spring plate inside some high-end Roller shutter doors, which is mainly used to apply a force on the shutter. It is prohibited to spring up when the Roller shutter is closed and fall when it is opened.

当卷帘门的卷轴出现问题时、弹簧片断裂后，卷帘门就会出现两种故障，卷帘门开启时会自动下落，自动下落时又会自动弹起。

When the roll of the Roller shutter has problems and the spring plate breaks, the Roller shutter will have two kinds of faults. When the Roller shutter is opened, it will fall automatically, and when it falls automatically, it will spring up again.

遇到这种情况，就直接将卷帘门的控制箱打开，查看弹簧片是否断裂或脱落，断裂了就直接更换，脱落了再将其挂回原位即可。

In this case, open the control box of the Roller shutter door directly to check whether the spring plate is broken or falling off. If it is broken, replace it directly. If it falls off, hang it back to its original position.

三、帘板故障

3、 Curtain panel failure

以彩钢条制作的卷帘门为例，卷帘门的帘板是由多块彩钢条压制成特制的形状，然后互相拼接在一起的，然后使用铆钉、固定条等将帘板固定在特定的位置里。

Take the Roller shutter made of color steel bars as an example. The shutter of Roller shutter is made of a number of color steel bars into a special shape, and then spliced together, and then fixed in a specific position with rivets, fixing strips, etc.

当帘板出现故障时，比如固定条磨损严重、铆钉脱落等，就会造成帘板断裂、变形、扭曲的情况，导致卷帘门无法正常使用。

When the shutter fails, for example, the fixing strip is severely worn and the rivet falls off, the shutter will break, deform and twist, resulting in the Roller shutter can not be used normally.

遇到这种情况，可以直接在松动的卷帘门上打孔，然后重新使用铆钉枪进行固定，然后再更换两边的固定条即可，也可以直接更换变形的帘板，然后再固定。

In this case, you can directly punch holes on the loose Roller shutter, and then re use the rivet gun to fix it, and then replace the fixing strips on both sides, or you can directly replace the deformed shutter and then fix it.

不过现在有很多卷帘门都是电动的，与器械卷帘门不同的是，它额外配置了电机、电机导轨、遥控设备等。这类卷帘门出现故障的原因比机械卷帘门更加复杂，不建议个人用户自行维修。更多相关事项就来我们网站http://www.jiahuawenti.cn咨询！

however, many roller shutter doors are electric. different from the roller shutter, it is additionally equipped with motors, motor rails, remote control equipment, etc. the reason for the failure of this type of roller shutter is more complicated than that of mechanical roller shutter, and it is not recommended that individual users repair it by themselves. for more related matters, come to our website http://www.jiahuawenti.cn consulting service
