早期的機械式卷簾門由簾板、座板、導軌、支座、卷軸、箱體、控制箱、卷門機、限位器、門楣、手動速放開關裝置、按鈕開關和保險裝置等組成。

The early mechanical Roller shutter is composed of shutter, base plate, guide rail, support, reel, box, control box, rolling door machine, limiter, door header, manual quick release switch device, button switch and safety device.

而容易出故障的位置就是導軌、卷軸、簾板這三項，如果是電動卷簾門，那么卷門機、控制箱等部位也有可能會出現故障，下面說說它的一些故障原因和解決方法。

The places that are 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、導軌故障

1、 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，先要檢查的就是導軌的摩擦條。

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 curtain plate 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。

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 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、卷軸故障

2、 Reel malfunction

卷軸除了負責將簾板卷起之外，它才存在一個隱性的拉力，有一些高檔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, 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.

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

三、簾板故障

3、 Curtain panel 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。

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.

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 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.

濟南卷簾門廠提醒，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。

Jinan Roller shutter Factory reminded that in this case, you can directly punch holes in the loose Roller shutter, and then use a 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.

不過現在有很多卷簾門都是電動的，與器械卷簾門不同的是，它額外配置了電機、電機導軌、遙控設備等。這類卷簾門出現故障的原因比機械卷簾門更加復雜，不建議個人用戶自行維修。更多相關事項就來我們網站http://m.santoncc.cn咨詢吧！

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.
