电动伸缩门的两种故障分析在很多时候我们会发现电动门会出现小问题，下面讲两个现象及分析和处理方法。
Analysis of two types of faults in electric telescopic doors often reveals small problems. Below are two phenomena and their analysis and handling methods.
现象：微机操作、就地操作电动门均不动作，电动门也没失电;
Phenomenon: Both microcomputer operation and local operation of the electric door do not operate, and the electric door does not lose power;
检查步骤：检查电动门机械是否沉，行程开关是否正常，远程、就地开关是否通断良好，门头内断项保护开关是否正常;
Inspection steps: Check whether the electric door mechanism is sinking, whether the travel switch is normal, whether the remote and local switches are in good condition, and whether the protection switch for broken items in the door head is normal;
电动门故障原因分析：亮绿灯属正常，红灯为缺项，如果红、绿灯均亮，属断项保护器故障。红灯亮、三项电不缺项，属断
Analysis of the cause of electric door failure: It is normal to turn on the green light, while the red light is missing. If both the red and green lights are on, it is a fault in the item protector. The red light is on, and there is no shortage of three items of electricity, which is considered as a disconnection
项保护器质量问题;
Quality issues with item protectors;
处理方法：将断项保护器的常闭接点短接，恢复正常操作。
Solution: Short circuit the normally closed contact of the disconnection protector and restore normal operation.
现象：以五期灰浆泵出口门为例，运行值班员联系开关能操作，门的开关方向不对，去就地操作观察，发现门的方向有时对，有时
Phenomenon: Taking the outlet door of the fifth phase mortar pump as an example, the operation duty officer contacted the switch to operate, but the direction of the door's opening and closing was incorrect. Upon on-site operation and observation, it was found that the direction of the door was sometimes correct, sometimes
不对，误认为电机相序有问题，至新换相序后，故障仍没排出;
No, I mistakenly believed that there was a problem with the motor phase sequence, and even after the new phase sequence was replaced, the fault still did not resolve;
检查步骤：检查不锈钢电动门电机三项直阻是否平衡，开、关行程是否正确，电动门机械是否沉;
Inspection steps: Check whether the three direct resistances of the stainless steel electric door motor are balanced, whether the opening and closing strokes are correct, and whether the electric door mechanism is sinking;
检查结果：电动门电机直阻少一项，行程正常，电动门机械不沉;
Inspection results: The direct resistance of the electric door motor is one item short, the stroke is normal, and the mechanical force of the electric door is not sinking;
故障原因分析：因电动门机械较轻，电机少一项，电机转动属自由状态，哪个方向较轻就朝哪个方向转动，所以，电动门开关方
Fault cause analysis: Due to the relatively light mechanical weight of the electric door, there is one missing item in the motor, and the motor rotates in a free state. The direction of rotation is the lightest, so the electric door switch is
向无法固定，此故障属缺项所至，将电机缺项恢复正常，故障消除。如果碰到这两种情况，可以相对应的看看，一些小的问题也
The direction cannot be fixed, and this fault is caused by a missing item. Restore the motor to normal and eliminate the fault. If you encounter these two situations, you can take a corresponding look, and some small problems are also
可以自己去解决。
You can solve it yourself.
