电动卷帘门怎么保养?

How to maintain electric rolling shutter doors?

1、定期清洁

1. Regular cleaning

很多时候一些小细节便会影响到电动卷帘门的正常使用，如电机里的灰尘过多、控制箱内有杂物等。所以日常使用时，还需定期对电动卷帘门的电机、

Many times, some small details can affect the normal use of electric rolling shutter doors, such as excessive dust in the motor and debris in the control box. So in daily use, it is also necessary to regularly check the motor of the electric rolling shutter door

控制箱等器件进行检查，并且及时清理掉其内的灰尘污物。

Inspect the control box and other components, and promptly clean the dust and dirt inside.

2、定期润滑

2. Regular lubrication

卷帘门的操作器以及转轴等处，使用次数一多难免会出现一些磨损，时间长了可能会出现开关不够顺畅的情况。所以在检修时，可以在摩擦频率高的区域滴一些润滑油，让电动卷帘门运作时能够减少零件间的摩擦，不仅能降低损坏几率，还能延长卷帘门的使用寿命。

The operator and rotating shaft of the rolling shutter door may inevitably experience some wear and tear after multiple uses, and over time, the opening and closing may not be smooth enough. So during maintenance, some lubricating oil can be dripped in areas with high friction frequency to reduce the friction between parts during the operation of the electric rolling shutter door. This not only reduces the probability of damage, but also extends the service life of the rolling shutter door.

3、谨慎维修

3. Careful maintenance

如果电动卷帘门出现了故障，不要着急自己上手维修，这是因为自己毕竟不是人员，误修可能还会导致雪上加霜。可以自己先排除一下是否是电源插头松动或电源方面出现了故障?若不是，则需请人士上门进行及时检修。

If the electric rolling shutter door malfunctions, don't rush to repair it yourself, because you are not a professional after all, and accidental repair may make things worse. Can you first rule out whether the power plug is loose or there is a problem with the power supply? If not, it is necessary to invite professionals to come and conduct timely maintenance.
