　　安装卷帘门在操作的时候会遇到很多的问题,当然在维修的时候也需要注意：

　　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)由于电动卷帘门维修与门锁、电动天线共用搭铁线,而产生一个典型故障:门锁不好用.开关卷帘门维修时收音机、升降器指示灯等小功率电器起作用,结果为搭铁点搭铁不实互相连电所致.

　　(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)拆装电动卷帘门维修时一定要注意正确的安装位置,其所有的螺栓连接孔为椭圆孔,定位前卷帘门维修升降一定不要发生干涉.

　　(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)电动卷帘门的尺寸精度将严重影响卷帘门维修升降器电机的寿命.因为导槽安装在电动卷帘门上,升降器又在导槽中运动.

　　(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)电动卷帘门的密封与防尘尤为重要:电动卷帘门内板有一层塑料防护层,其破损后会导致灰尘进入电动卷帘门内,严重时将干涉电动卷帘门维修的运动.

　　(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
