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、電動卷簾門是否支持手動功能，手動要方便，快捷。停電時將離合扭轉90度，即可手推運行。

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、電動卷簾門不能存在慣性滑行的現象，要具有雙面自動卡鎖功能。

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

三、為了提高電動卷簾門運行平穩程度，要增強拉力，所以本廠采用的是8輪前后驅動，連排齒輪轉動的生產安裝技術。

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、觀察電動卷簾門的結構是否精 密，潤滑程度好壞，好的電動卷簾門散熱比較，采用全齒輪轉動，無鏈條、無皮帶，進而增強了卷簾門機芯整體壽命。

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.

安裝方法

Installation method

一、先在需要安裝的門框框口位置畫出線。表明尺寸大小，然后找工作人員設計出合適的電動卷簾門，這里值得注意的一點是框內高度比門扇的高度要高一點點。

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、先把電動卷簾門的門框固定，這里要先拆掉門框下部的固定板。（注意：洞口兩側地面要預留凹槽，經校正合格后，固定木楔，門框鐵腳與預埋鐵板件焊牢。用水泥砂漿或強度不低于10MPa細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、安裝電動卷簾門扇主體門扇。一定要保證電動卷簾門與墻體結成整體，封閉性要做好，再粉刷洞口及墻體。粉刷完畢后，門縫應均勻平整，開啟電動卷簾門應該自 由輕便，不得有過緊、過松和反 彈現象。

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.
