第一、就算是比较不错的电动伸缩门如果在日常使用中，计划的功能、性能不能发挥，故障百出的话，一处开口部分的故障将影响整体建筑物的效果。因此必须进行充分的保养，让其一直保持正常运转。
Firstly, even if it is a relatively good electric retractable door, if its planned function and performance cannot be fully utilized in daily use, and if there are numerous faults, the failure of one opening part will affect the overall effect of the building. Therefore, sufficient maintenance must be carried out to keep it running normally at all times.
第二、为了将电动伸缩门使用期间的故障防患未燃，维持良好的运行机能，确保安全，必须有计划的进行维修保养。为此就有必要收集保养管理数据，进行统计处理。
Secondly, in order to prevent faults during the use of electric retractable doors from igniting, maintain good operating function, and ensure safety, planned maintenance and repair must be carried out. Therefore, it is necessary to collect maintenance management data and conduct statistical processing.
第三、因为电动伸缩门整体具有一贯性，即使一个很小的故障也会影响整体。即使小故障，如果发现因及时维修，不使其故障变大。
Thirdly, due to the overall consistency of the electric telescopic door, even a small fault can affect the overall performance. Even if a minor malfunction is found, timely repair will not make it bigger.
电动伸缩门为什么老是自动开?
Why do electric retractable doors always open automatically?
1.一种情况是，电动伸缩门遥控器的接收部分对于信号的抗干扰能力不强造成的，因为周围环境会有很多电磁波，这些电磁波会对遥控器造成干扰。那要如何解决呢?
1. One situation is that the receiving part of the electric telescopic door remote control has weak anti-interference ability to the signal, because there are many electromagnetic waves in the surrounding environment, which can cause interference to the remote control. How can we solve it?
2.办法是更换一个新的遥控器是最好的办法，但是如果不能更换的话，就需要做一些改善的工作了。比如说金属箔对遥控器做一下包裹，然后做型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵开门和关门测试，直到能够正常开启电动伸缩门就可以。
The solution is to replace the remote control with a new one, but if it cannot be replaced, some improvement work needs to be done. For example, wrapping the remote control with metal foil and conducting door opening and closing tests until the electric retractable door can be opened normally.
3.另外一种情况是电动伸缩门电机设置了自动开门的功能。这个问题就比较容易解决了，我们可以查看说明书或者咨询厂家的售后服务中心来重新设置关闭自动开门的功能就可以了。
Another situation is that the electric telescopic door motor is equipped with an automatic door opening function. This problem is relatively easy to solve. We can refer to the manual or consult the manufacturer's after-sales service center to reset the automatic door opening function.
