卷帘门故障一般就是三种要注意维修

很多朋友在安装、使用卷帘门时，经常会遇到一些故障，又不知道是什么原因造成的，也不知道该如何维修，下面就来说说卷帘门常见的故障和维修方法。

Many friends often encounter some faults when installing and using roller shutter doors, and they don't know what causes them or how to repair them. Here are the common faults and maintenance methods of roller shutter doors.

导轨故障

Guide rail failure

正常来讲，无论是哪一种卷帘门，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，首先要检查的就是导轨的摩擦条。

Normally, no matter what kind of roller shutter door, there is a layer of "friction strip" inside the guide rails on both sides, which is used to avoid the friction between the curtain plate and the guide rail. When the roller shutter door 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。

Friction strips are consumables. Pushing and pulling the roller shutter door often will lead to the loss of friction strips. If there is no friction strip, the roller shutter door will be in direct contact with the guide rail, and the roller shutter door 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 case, you can directly buy the friction strip to replace it. If you can't replace it yourself, you can call the installation manufacturer to help after-sales.

卷轴故障

Reel failure

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 is a spring leaf inside some high-end shutter doors, which is mainly used to exert a force on the shutter to prevent the shutter door from bouncing up when it is closed and falling 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 there is a problem with the roller of the roller shutter door and the spring is broken, the roller shutter door will have two kinds of faults. When the roller shutter door is opened, it will fall automatically, and when it falls automatically, it will bounce up automatically.

济南防火卷帘门安装维修人员认为遇到这种情况，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。

Jinan fire shutter door installation and maintenance personnel believe that in this case, they will directly open the control box of the shutter door, check whether the spring is broken or falling off, and directly replace it if it is broken, and then hang it back to its original position if it falls off.

帘板故障

Curtain board 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 door made of color steel bars as an example. The shutter plate of roller shutter door is pressed into a special shape by multiple color steel bars, and then spliced together, and then rivets, fixing strips, etc. are used to fix the shutter plate in a specific position.

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 curtain panel breaks down, such as the fixed strip is seriously worn and the rivet falls off, it will cause the curtain panel to break, deform and distort, resulting in the failure of the roller shutter door.

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 in the loose roller shutter door, and then use the rivet gun to fix it again, and then replace the fixing strips on both sides, or you can directly replace the deformed curtain plate, and then fix it.

而容易出故障的位置就是导轨、卷轴、帘板这三项，如果是防火卷帘门，那么卷门机、控制箱等部位也有可能会出现故障，以上希望您能认真看待。更多相关事项就来我们网站http://www.jnyuqilin.com吧。

The positions that are prone to failure are the guide rail, roller and curtain board. If it is a fire-proof roller shutter door, the roller door machine, control box and other parts may also fail.
