　　安裝卷簾門在操作的時候會遇到很多的問題,當然在維修的時候也需要注意：

　　There are many problems in the operation of installing the rolling shutter door. Of course, attention should be paid to the following during the maintenance:

　　(1)由于電動卷簾門維修與門鎖、電動天線共用搭鐵線,而產生一個典型故障:門鎖不好用.開關卷簾門維修時收音機、升降器指示燈等小功率電器起作用,結果為搭鐵點搭鐵不實互相連電所致.

　　(1) Due to the common ground wire used by the electric roller shutter door maintenance, the central door lock and the electric antenna, a typical fault occurs: the central door lock is not easy to use. When the roller shutter door is opened and closed for maintenance, the radio, the indicator light of the elevator and other small power appliances work, resulting in the fact that the ground points are not connected to each other

　　(2)拆裝電動卷簾門維修時一定要注意正確的安裝位置,其所有的螺栓連接孔為橢圓孔,定位前卷簾門維修升降一定不要發生干涉.

　　(2) When disassembling and assembling the electric roller shutter door for maintenance, pay attention to the correct installation position. All the bolt connection holes are oval holes. Do not interfere with the maintenance lifting of the front roller shutter door before positioning

　　(3)電動卷簾門的尺寸精度將嚴重影響卷簾門維修升降器電機的壽命.因為導槽安裝在電動卷簾門上,升降器又在導槽中運動.

　　(3) The dimension accuracy of the electric roller shutter will seriously affect the service life of the lifter motor. Because the guide slot is installed on the electric roller shutter, the lifter moves in the guide slot

　　(4)電動卷簾門的密封與防塵尤為重要:電動卷簾門內板有一層塑料防護層,其破損后會導致灰塵進入電動卷簾門內,嚴重時將干涉電動卷簾門維修的運動.

　　(4) The sealing and dustproof of the electric roller shutter is particularly important: the inner plate of the electric roller shutter has a plastic protective layer, which will cause dust to enter the electric roller shutter when it is damaged, and will interfere with the maintenance movement of the electric roller shutter when it is serious
