The positions where the rolling shutter door is easy to fail are the guide rail, roller and curtain plate. If it is an electric rolling shutter door, the rolling shutter machine, control box and other parts may also fail. Let's take the mechanical rolling shutter door as an example to talk about some of its failure causes and solutions.

一、導軌故障

1、 Guide rail failure

正常來講，無論是哪一種卷簾門，兩邊的導軌內部都是有一層“磨擦條”存在的，這層摩擦條的作用是避免簾板與導軌摩擦而存在的。當卷簾門無法上拉、下拉時，要檢查的就是導軌的摩擦條。

Normally speaking, no matter what kind of rolling shutter door, there is a layer of "friction strip" inside the guide rails on both sides. The function of this layer of friction strip is to avoid the friction between the curtain plate and the guide rail. When the rolling shutter door cannot be pulled up or down, the first thing to check is the friction strip of the guide rail.

摩擦條屬于易消耗品，經常推拉卷簾門會導致摩擦條損耗，如果沒有了摩擦條，卷簾門會跟導軌直接接觸，就會出現卷簾門無法上拉、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, resulting in the failure that the roller shutter door cannot be pulled up or down.

遇到這種情況，直接去購買摩擦條更換即可，如果自己不會更換，可以給安裝廠家打電話，讓其幫忙售后。

In this case, you can directly buy the friction strip and replace it. If you can't replace it, you can call the installation manufacturer to help after-sales.

二、卷軸故障

2、 Reel failure

卷軸除了負責將簾板卷起之外，它才存在一個隱性的拉力，有一些質量比較高的卷簾門內部會有一個彈簧片存在，主要作用是對簾板施加一個力，禁止卷簾門在關閉的時候彈起，在打開的時候下落。

In addition to being responsible for rolling up the shutter plate, the reel has a hidden tension. There will be a spring plate inside some high-quality shutter doors, which is mainly used to exert a force on the shutter plate to prevent the shutter door from bouncing up when it is closed and falling when it is opened.

當卷簾門的卷軸出現問題時、彈簧片斷裂后，卷簾門就會出現兩種故障，卷簾門開啟時會自動下落，自動下落時又會自動彈起。

When there is a problem with the roller of the rolling shutter door and the spring plate is broken, the rolling shutter door will have two kinds of faults. The rolling shutter door will fall automatically when it is opened and bounce up automatically when it falls automatically.

遇到這種情況，就直接將卷簾門的控制箱打開，查看彈簧片是否斷裂或脫落，斷裂了就直接更換，脫落了再將其掛回原位即可。

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

三、簾板故障

3、 Curtain plate failure

以彩鋼條制作的卷簾門為例，卷簾門的簾板是由多塊彩鋼條壓制成特制的形狀，然后互相拼接在一起的，然后使用鉚釘、固定條等將簾板固定在特定的位置里。

Taking the rolling shutter door made of color steel bars as an example, the curtain plate of rolling shutter door is pressed into a special shape by multiple color steel bars, and then spliced with each other, and then the curtain plate is fixed in a specific position by rivets, fixing strips, etc.

當簾板出現故障時，比如固定條磨損嚴重、鉚釘脫落等，就會造成簾板斷裂、變形、扭曲的情況，導致卷簾門無法正常使用。

When the curtain plate breaks down, such as the serious wear of the fixing strip and the falling off of the rivets, it will cause the fracture, deformation and distortion of the curtain plate, resulting in the failure of the rolling shutter door.

遇到這種情況，可以直接在松動的卷簾門上打孔，然后重新使用鉚釘槍進行固定，然后再更換兩邊的固定條即可，也可以直接更換變形的簾板，然后再固定。

In this case, you can directly punch holes in the loose rolling shutter door, and then use the rivet gun to fix it again, and then replace the fixing strips on both sides. You can also directly replace the deformed shutter plate, and then fix it.
