1 不锈钢电动伸缩门运行过程中打颤不锈钢电动伸缩门道闸运行的过程中，往往会出现一些打颤现象，而且有的时候越来越严重。对于这种问题的出现，自动不锈钢伸缩门维修主要是要弄清楚原因，例如是否因为闸杆长度与弹簧拉力不成正比所导致的，如果下杆不会颤，起杆会颤，说明是拉簧弹力过强，当然了如果反之，那么就说明是拉簧弹力不足，应该适当的调紧。

During the operation of stainless steel electric telescopic gate gate, there will often be some shivering phenomenon, and sometimes more and more serious. For the occurrence of this problem, automatic stainless steel telescopic door maintenance is mainly to figure out the reasons, such as whether the brake rod length and spring tension is not proportional to the cause, if the rod will not flutter, the rod will flutter, indicating that the spring elasticity is too strong, of course, if on the contrary, then it shows that the spring elasticity is insufficient, should be properly tightened.

2 伸缩门遇到的最大的一个问题就是不能开关，遇到这样的问题的时候，维修首先要检查有无通电、保险管有无烧毁，如果保险丝溶断了，必须要做全面检查。一般来说，如果不能开关，一般是线路出现了问题，所以要测量红、白、黄三条引线是否相通，主要是看三条线路在哪里出现的问题

One of the biggest problems encountered by the telescopic door is that it can not be switched on. When encountering such a problem, the maintenance should first check whether there is electricity, and whether the fuse is burned. If the fuse is broken, a comprehensive inspection must be done. Generally speaking, if you can't switch, generally there is a problem with the line, so to measure whether the red, white, yellow three leads are connected, mainly to see where the three lines appear
