Many friends often encounter some faults when installing and using the roller shutter door. They don't know what causes them or how to repair them. What if there is a problem with the guide rail, roller and shutter? Jinan roller shutter manufacturer will analyze for you:
1、 Guide rail fault
Normally, no matter what kind of roller shutter door is, there is a layer of "friction strip" inside the guide rail on both sides. The function of this layer of friction strip is to avoid the friction between the shutter 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. The friction strip is a consumable. Frequent pushing and pulling of the roller shutter will cause the wear of the friction strip. If there is no friction strip, the roller shutter will directly contact with the guide rail, and the roller shutter will fail to pull up and down.
In this case, just go to buy the friction strip and replace it. If you can't replace it yourself, you can call the installation manufacturer and ask them to help with after-sales service.
2、 Reel fault
In addition to being responsible for rolling up the shutter, the roller has a hidden pull force. There is a spring leaf inside some high-end shutter doors, which is mainly used to exert a force on the shutter. It is forbidden to spring up when closing and fall when opening. When there is a problem with the roller of the roller shutter door and the spring plate breaks, the roller shutter door will have two kinds of faults. The roller shutter door will automatically fall when it is opened, and will automatically spring up when it automatically falls.
In this case, open the control box of the 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.
3、 Curtain failure
Take the roller shutter made of color steel bars as an example. The shutter of the roller shutter is made of a number of color steel bars pressed into a special shape, then spliced together, and then fixed in a specific position with rivets, fixing strips, etc. When the curtain board fails, such as severe wear of the fixing strip and falling off of the rivet, it will cause the curtain board to break, deform and twist, resulting in the failure of normal use of the rolling shutter door.
In this case, you can directly punch holes in the loose roller shutter door, then use the rivet gun again to fix it, and then replace the fixing strip on both sides, or you can directly replace the deformed shutter, and then fix it.
However, many roller shutter doors are electric now. Unlike the instrument roller shutter doors, they are additionally equipped with motors, motor guides, remote control equipment, etc. The reason for the failure of this type of roller shutter door is more complex than that of the mechanical roller shutter door. It is not recommended for individual users to repair by themselves. If you have any questions about rolling shutter door, please contact us //emblembonsai.com Come on!
