The service life of the fast door is not only a quality problem, but also closely related to the correct daily use and maintenance. Let's take a look at the maintenance methods and tips of express door

要定期檢查： 定期查看門軌、門扇有無變形、卡阻現象，操作按鈕是否良好，按鈕箱門是否可鎖。卷簾門上電控制箱指示信號是否正常，箱體有無受損。開啟按鈕箱門，按下上方(或下方)按鈕，卷簾門應上升或下降，如果卷簾門升降與按鈕操作上下不一樣，必須立即停車，調整電源項序后方可重新操作。在按鈕操作上升(或下降)過程中，操作人員嚴禁離開現場，操作的同時，要密切注意卷簾門上升(或下降)到一定位置后是否能自動停車。如果卷簾門上升即將出導軌(或下降已到地面)仍不停車，必須待限位裝置修復(調整)正常后方可重新操作。

First of all, regular inspection: regularly check whether the door rail and door leaf are deformed and jammed, whether the operation button is good, and whether the button box door can be locked. Whether the indication signal of the electric control box on the rolling shutter door is normal and whether the box is damaged. Open the door of the button box and press the upper (or lower) button, the rolling shutter door should rise or fall. If the lifting of the rolling shutter door is different from the up and down operation of the button, it must stop immediately and adjust the power sequence before re operation. In the process of button operation rising (or descending), the operator is strictly forbidden to leave the site. At the same time, pay close attention to whether the rolling shutter door can automatically stop after rising (or descending) to a certain position. If the rolling shutter door is about to go out of the guide rail (or has fallen to the ground) and still does not stop, it must be operated again after the limit device is repaired (adjusted) normally.

其次就是高速卷簾門的電機保養： 保養流程：清洗定轉子——更換碳刷或其他零部件——真空F級壓力浸漆——烘干——校動平衡。

The second is the motor maintenance of high-speed rolling shutter door: maintenance process: cleaning stator and rotor - replacing carbon brush or other parts - vacuum f-level pressure impregnation - drying - dynamic balance calibration.

1、使用環境應經常保持干燥，電動機表面應保持清潔，進風口不應受塵土、纖維等阻礙。

1. The operating environment should be kept dry, the motor surface should be kept clean, and the air inlet should not be blocked by dust and fiber.

2、當電動機的熱保護連續發生動作時，應查明故障來自電動機還是超負荷或保護裝置整定值太低，故障后，方可投入運行。 3、應保證電動機在運行過程中良好的潤滑。一般的電動機運行5000小時左右，即應補充或更換潤滑脂，運行中發現軸承過熱或潤滑變質時，液壓及時換潤滑脂。更換潤滑脂時，應舊的潤滑油，并有汽油洗凈軸承及軸承蓋的油槽，然后將ZL-3鋰基脂填充軸承內外圈之間的空腔的1/2(對2極)及2/3(對4、6、8極)。

2. When the thermal protection of the motor continuously acts, it is necessary to find out whether the fault is from the motor or overload or the setting value of the protection device is too low. After the fault is eliminated, it can be put into operation. 3. The motor shall be well lubricated during operation. The general motor runs for about 5000 hours, that is, the lubricating grease should be supplemented or replaced. When the bearing is overheated or the lubrication is deteriorated, the hydraulic pressure should change the lubricating grease in time. When replacing the grease, the old lubricating oil should be removed, and the oil groove of bearing and bearing cover should be cleaned with gasoline. Then, zl-3 lithium grease should be filled into 1 / 2 (for 2 poles) and 2 / 3 (for 4,6,8 poles) of the cavity between the inner and outer rings of the bearing.

4、當軸承的壽命終了時，電動機運行的振動及噪聲將明顯增大，檢查軸承的徑向游隙達到下列值時，即應更換軸承。

4. When the service life of the bearing is over, the vibration and noise of the motor will increase obviously. When the radial clearance of the bearing reaches the following value, the bearing should be replaced.

5、拆卸電動機時，從軸伸端或非伸端取出轉子都可以。如果沒有必要卸下風扇，還是從非軸伸端取出轉子較為便利，從定子中抽出轉子時，應防止損壞定子繞組或絕緣。

5. When disassembling the motor, take out the rotor from the shaft extension end or non extension end. If it is not necessary to remove the fan, it is more convenient to take out the rotor from the non shaft extension end. When the rotor is pulled out from the stator, the stator winding or insulation shall be prevented from being damaged.

6、更換繞組時必須記下原繞組的形式，尺寸及匝數，線規等，當失落了這些數據時，應向制造廠索取，隨意更改原設計繞組，常常使電動機某項或幾項性能惡化，甚于無法使用。

6. When replacing the winding, the form, size, turns and wire gauge of the original winding must be recorded. When these data are lost, they should be obtained from the manufacturer, and the original designed winding can be changed at will. As a result, the performance of one or several items of the motor will deteriorate, and even can not be used.
