The operation and prevention process of the rolling shutter is very simple, but the rolling shutter adopts high-quality manufacturing method, which simplifies the maintenance work for users. The processing of damaged parts of the shutter can be divided into two ways: maintenance and replacement.

对于可以继续使用、经过处理后可以继续使用的零件，应选用修复的方式进行处理，利于节省机械的维修成本。零件在设计前，相关人员就考虑到了磨损现象发生的可能性，通过对零件位置的调整、间隙的调整，便可以恢复传动结构的使用功能，这种调节方法通常用于零件磨损、变形不太严重的场合。将磨损部位通过机械加工进行去除，再在此部位设计并安装一个补充尺寸的零件，以恢复此零件的使用功能也是常用的修复方式。

For the parts that can be used continuously and can be used after treatment, the repair method should be selected for treatment, which is conducive to saving the maintenance cost of machinery. Before the design of parts, relevant personnel have considered the possibility of wear phenomenon. By adjusting the position and clearance of parts, the use function of transmission structure can be restored. This adjustment method is usually used in the situation where parts are not seriously worn and deformed. It is also a common repair method to remove the worn part by machining, and then design and install a supplementary size part in this part to restore the use function of this part.

但对于卷帘门易损件的处理来说，就需要采取及时更换的方式，某些部件在卷帘门长期使用的情况下磨损严重，其原有材料损失量很大，此时不仅修补的意义不大，更可能因为修复材料与原有材料的区别而导致零件整体强度不足。

However, for the treatment of vulnerable parts of the rolling shutter door, it is necessary to replace them in time. Some parts are seriously worn when the rolling shutter door is used for a long time, and the loss of the original materials is large. At this time, not only is the repair of little significance, but also the overall strength of the parts may be insufficient due to the difference between the repair materials and the original materials.
