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

要定期检查： 定期查看门轨、门扇有无变形、卡阻现象，操作按钮是否良好，按钮箱门是否可锁。卷帘门上电控制箱指示信号是否正常，箱体有无受损。开启按钮箱门，按下上方(或下方)按钮，卷帘门应上升或下降，如果卷帘门升降与按钮操作上下不一样，必须立即停车，调整电源项序后方可重新操作。在按钮操作上升(或下降)过程中，操作人员严禁离开现场，操作的同时，要密切注意卷帘门上升(或下降)到一定位置后是否能自动停车。如果卷帘门上升即将出导轨(或下降已到地面)仍不停车，必须待限位装置修复(调整)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.

其次就是高速卷帘门的电机保养： 保养流程：清洗定转子——更换碳刷或其他零部件——真空F级压力浸漆——烘干——校动平衡。

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、使用环境应经常保持干燥，电动机表面应保持清洁，进风口不应受尘土、纤维等阻碍。

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、当电动机的热保护连续发生动作时，应查明故障来自电动机还是超负荷或保护装置整定值太低，故障后，方可投入运行。 3、应保证电动机在运行过程中良好的润滑。一般的电动机运行5000小时左右，即应补充或更换润滑脂，运行中发现轴承过热或润滑变质时，液压及时换润滑脂。更换润滑脂时，应旧的润滑油，并有汽油洗净轴承及轴承盖的油槽，然后将ZL-3锂基脂填充轴承内外圈之间的空腔的1/2(对2极)及2/3(对4、6、8极)。

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、当轴承的寿命终了时，电动机运行的振动及噪声将明显增大，检查轴承的径向游隙达到下列值时，即应更换轴承。

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、拆卸电动机时，从轴伸端或非伸端取出转子都可以。如果没有必要卸下风扇，还是从非轴伸端取出转子较为便利，从定子中抽出转子时，应防止损坏定子绕组或绝缘。

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、更换绕组时必须记下原绕组的形式，尺寸及匝数，线规等，当失落了这些数据时，应向制造厂索取，随意更改原设计绕组，常常使电动机某项或几项性能恶化，甚于无法使用。

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.
