With the development of science and technology, people's life gradually tends to automation, electric roller shutter door is widely used. This paper mainly introduces the selection and installation of electric rolling shutter door. For the selection of curtain specifications, generally small single garage door (width less than 3m, height less than 2.5m) choose Model 55 or model 77, large double garage door choose model 77. Jinan rolling shutter door system supporting rolling shutter garage door roller generally selects 80 mm diameter circular tube, according to the size of the door, the size of the end seat is different, to determine whether the use of the case. How to choose

一、电动卷帘门是否支持手动功能，手动要方便，快捷。停电时将离合扭转90度，即可手推运行。

1、 Whether the electric rolling shutter door supports the manual function, the manual operation should be convenient and fast. In case of power failure, turn the clutch 90 degrees, and then push it manually.

二、电动卷帘门不能存在惯性滑行的现象，要具有双面自动卡锁功能。

2、 The electric rolling shutter door shall not have the phenomenon of inertia sliding, and shall have double-sided automatic locking function.

三、为了提高电动卷帘门运行平稳程度，要增强拉力，所以本厂采用的是8轮前后驱动，连排齿轮转动的生产安装技术。

3、 In order to improve the smooth operation of the electric rolling shutter door, to enhance the tension, so the factory adopts the production and installation technology of 8-wheel front and rear drive, continuous row gear rotation.

四、观察电动卷帘门的结构是否精 密，润滑程度好坏，好的电动卷帘门散热比较，采用全齿轮转动，无链条、无皮带，进而增强了卷帘门机芯整体寿命。

4、 Observe whether the structure of the electric rolling shutter door is precise, the lubrication degree is good or bad, good electric rolling shutter door heat dissipation comparison, using full gear rotation, no chain, no belt, thus enhancing the overall service life of the rolling shutter door movement.

安装方法

Installation method

一、先在需要安装的门框框口位置画出线。表明尺寸大小，然后找工作人员设计出合适的电动卷帘门，这里值得注意的一点是框内高度比门扇的高度要高一点点。

1、 First, draw the outgoing line at the position of the door frame to be installed. Show the size, and then find the staff to design a suitable electric roller shutter door. It is worth noting that the height of the frame is a little higher than that of the door leaf.

二、先把电动卷帘门的门框固定，这里要先拆掉门框下部的固定板。（注意：洞口两侧地面要预留凹槽，经校正合格后，固定木楔，门框铁脚与预埋铁板件焊牢。用水泥砂浆或强度不低于10MPa细石混凝土嵌塞牢固即可。）

2、 First, fix the frame of the electric rolling shutter door. Here, first remove the fixing plate at the lower part of the frame（ Note: grooves shall be reserved on the ground at both sides of the hole. After the correction is qualified, the wooden wedge shall be fixed, and the iron foot of the door frame shall be firmly welded with the embedded iron plate. Cement mortar or fine aggregate concrete with strength not less than 10MPa can be used to firmly plug.)

三、安装电动卷帘门扇主体门扇。一定要保证电动卷帘门与墙体结成整体，封闭性要做好，再粉刷洞口及墙体。粉刷完毕后，门缝应均匀平整，开启电动卷帘门应该自 由轻便，不得有过紧、过松和反 弹现象。

3、 Install the main door leaf of electric rolling shutter door leaf. We must ensure that the electric rolling shutter door and the wall form a whole, the sealing should be done well, and then paint the hole and the wall. After painting, the door seam should be even and smooth, and the opening of the electric roller shutter door should be free and light, without too tight, too loose and rebound phenomenon.
