With the development of science and technology, people's life gradually tends to automation, and electric roller shutter doors are widely used. This paper mainly introduces the selection and installation method of electric rolling shutter door. For the selection of curtain specifications, generally, 55 or 77 curtain is selected for small single car garage doors (width within 3M and height within 2.5m), and 77 curtain is selected for large double garage doors. The roller shaft of Jinan rolling shutter garage door supporting the rolling shutter door system generally adopts a circular pipe with a diameter of 80mm. The size of the end seat varies according to the size of the door, and whether the cover is required is determined according to the use situation.

一、電動(dòng)卷簾門(mén)是否支持手動(dòng)功能，手動(dòng)要方便，快捷。停電時(shí)將離合扭轉90度，即可手推運行。

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

二、電動(dòng)卷簾門(mén)不能存在慣性滑行的現象，要具有雙面自動(dòng)卡鎖功能。

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

三、為了提高電動(dòng)卷簾門(mén)運行平穩程度，要增強拉力，所以本廠(chǎng)采用的是8輪前后驅動(dòng)，連排齒輪轉動(dòng)的生產(chǎn)安裝技術(shù)。

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

四、觀(guān)察電動(dòng)卷簾門(mén)的結構是否精密，潤滑程度好壞，好的電動(dòng)卷簾門(mén)散熱比較，采用全齒輪轉動(dòng)，無(wú)鏈條、無(wú)皮帶，進(jìn)而增強了卷簾門(mén)機芯整體壽命。

4、 Observe whether the structure of the electric rolling shutter door is precise and the lubrication degree is good or bad. A good electric rolling shutter door has better heat dissipation. It adopts full gear rotation without chain and belt, so as to enhance 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(mén)框框口位置畫(huà)出線(xiàn)。表明尺寸大小，然后找工作人員設計出合適的電動(dòng)卷簾門(mén)，這里值得注意的一點(diǎn)是框內高度比門(mén)扇的高度要高一點(diǎn)點(diǎn)

1、 Draw the outgoing line at the door frame opening to be installed. Indicate the size, and then find the staff to design a suitable electric rolling shutter door. It is worth noting that the height in the frame is a little higher than that of the door leaf

二、先把電動(dòng)卷簾門(mén)的門(mén)框固定，這里要先拆掉門(mén)框下部的固定板。（注意：洞口兩側地面要預留凹槽，經(jīng)校正合格后，固定木楔，門(mén)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 door frame of the electric rolling shutter door. Here, remove the fixing plate at the lower part of the door frame（ Note: grooves shall be reserved on the ground on both sides of the hole. After correction, fix the wooden wedge, and weld the iron foot of the door frame with the embedded iron plate. Cement mortar or fine aggregate concrete with strength not less than 10MPa can be used to plug firmly.)

三、安裝電動(dòng)卷簾門(mén)扇主體門(mén)扇。一定要保證電動(dòng)卷簾門(mén)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(mén)縫應均勻平整，開(kāi)啟電動(dòng)卷簾門(mén)應該自由輕便，不得有過(guò)緊、過(guò)松和反彈現象。

3、 Install the main body of the electric rolling shutter door leaf. It must be ensured that the electric rolling shutter door and the wall form a whole, and the sealing shall be done well, and then the hole and wall shall be painted. After painting, the door seam shall be even and flat, and the opening of the electric rolling shutter door shall be free and light without too tight, too loose and rebound.
