伸缩门是我们日常生活中经常可以看见的门类了，它广泛的应用于学校或者是单位等公共的场所。但是风吹日晒的久了，总会产生各种各样的问题。接下来小编就来给大家介绍下伸缩门故障处理小技巧，

Telescopic door is a kind of door that we can often see in our daily life. It is widely used in schools, units and other public places. But after a long time, there will always be various problems. Next, let's introduce some tips for troubleshooting the telescopic door,

伸缩门故障处理——停机问题

Troubleshooting of telescopic door - shutdown

有一种情况就是伸缩门可以开关，却不能停机。可以开关说明伸缩门的电机线和信号线是正常的，而不能停机则有可能是因为限位信号没有送到控制器或控制器限位功能损坏而造成的。这时候可以通过修复断开的电路，进而达到维修伸缩门的目的。

In one case, the telescopic door can be opened and closed, but it cannot be shut down. The switch indicates that the motor line and signal line of the telescopic door are normal, while the failure to shut down may be caused by the failure of the limit signal to the controller or the damage of the limit function of the controller. At this time, the disconnected circuit can be repaired to maintain the telescopic door.

伸缩门故障处理——颤抖问题

Troubleshooting of telescopic door - shaking problem

伸缩门在闸道里运行的过程中可能会出现打颤的现象，并可能会随着时间变得越来越严重，这个时候就需要去检查闸杆长度与弹簧拉力是否还成正比。如果下杆不会颤但起杆会颤就说明是拉簧弹力过强，如果反之，那么就说明是拉簧弹力不足，此时应该适当的调紧了。

The telescopic door may vibrate during its operation in the gate, and may become more and more serious over time. At this time, it is necessary to check whether the length of the gate rod is still proportional to the spring tension. If the lower rod will not vibrate but the rising rod will vibrate, it means that the tension spring is too elastic. If the opposite is true, it means that the tension spring is insufficient. At this time, it should be properly tightened.

伸缩门故障处理——倒退问题

Troubleshooting of telescopic door - reverse problem

伸缩门经常回出现的另一个故障就是自动倒退了，出现这种情况的原因应该是红外线抗干扰能力变差而导致的，也可能是对射感应而产生的错误的动作，要解决这种问题一般是采取编码或者是更换PCB板来解决，也可将红外线输出继电器的推动三极管在be极间接一只47uf的电解电容来滤波外界的干扰。当然如果是红外线出现了问题，的办法就是进行更换以确保伸缩门的正常的使用。

Another common fault of the telescopic door is the automatic reverse. The reason for this should be the poor anti-interference ability of the infrared ray, or the wrong action caused by the radiation induction. To solve this problem, it is generally to adopt coding or change the PCB. It is also possible to indirectly filter the external interference by using a 47uF electrolytic capacitor at the be pole of the push triode of the infrared output relay. Of course, if there is an infrared problem, the best way is to replace it to ensure the normal use of the telescopic door.

此外济南卷帘门厂家认为还需将伸缩门的保养列入计划，并记录在设备日常保养表中。比如：

In addition, Jinan roller shutter door manufacturer believes that the maintenance of the telescopic door should be included in the plan and recorded in the daily maintenance table of the equipment. For example:

经常检查伸缩门的上下行程开关，如果发现干涩，及时加入滑轨润滑油。经常检查电动刹车手动开关和手动起闸装置，看有无失效现象。远离防腐蚀物品远离酸性、腐蚀性化学物品，以免灼伤伸缩门外表。检查运行状况经常检查伸缩门的运行状况，令伸缩门开启或关闭处于适当的位置，测试过程严防伸缩门冲顶或冲底。

Check the up and down travel switches of the telescopic door frequently. If it is found dry, add the sliding rail lubricating oil in time. Regularly check the manual switch of electric brake and manual brake starting device to see if there is any failure. Keep away from anti-corrosive articles and acidic and corrosive chemicals to avoid burning the appearance of the telescopic door. Check the operation condition. Check the operation condition of the telescopic door frequently to make the opening or closing of the telescopic door in an appropriate position. During the test, strictly prevent the telescopic door from hitting the top or bottom.

定期清洗伸缩门外表，时常检查其运行状况，擦洗伸缩门时尽量选择柔软的棉丝或纱布，放置划坏电动伸缩门。当遇到顽固污渍时，可使用清水、酒精或中性洗涤剂、进行清洗。伸缩门上有很多五金配件，这些五金需要进行定期的保养和维护，否则的话将会很容易生锈和老化，如果发现损坏的现象，及时地进行替换或者修补。

Clean the appearance of the telescopic door regularly, and check its operation condition frequently. When scrubbing the telescopic door, try to select soft cotton or gauze, and place the scratched electric telescopic door. In case of stubborn stains, clean them with clean water, alcohol or neutral detergent. There are many hardware fittings on the telescopic door, which need regular maintenance. Otherwise, it will be easy to rust and age. If damage is found, it should be replaced or repaired in time.
