电动伸缩门发生故障是常有的事
电动伸缩门发生故障是常有的事,尤其是使用年限比较久的那种,发生故障的机率就更大,更频繁。所以,了解一些电动伸缩门发生故障的原因能帮助我们有效解决问题,是很有必要的。
It is common for electric retractable doors to malfunction, especially
for those that have been in use for a long time. The probability of
malfunction is higher and more frequent. Therefore, it is necessary to
understand the reasons for the malfunction of electric telescopic doors,
which can help us effectively solve the problem.
电动伸缩门发生故障的原因有很多种情况,我们会发现电动伸缩门觉见的问题就那两种。下面我们就对这两种情况进行分析和处理方法进行说明。
There are many reasons for the malfunction of electric telescopic doors,
and we will find that there are only two types of problems with the
perception of electric telescopic doors. Below, we will analyze and
explain the methods for handling these two situations.
现象一:微机操作和本地操作的伸缩门不动作,也不失电;
Phenomenon 1: The telescopic doors operated by microcomputers and locally do not operate or lose power;
检查步骤:检查电动伸缩门是否机械下沉,行程开关是否正常,远方和就地开关是否接触良好和断开,门头上的断件保护开关是否正常;
Inspection steps: Check whether the electric telescopic door is
mechanically sinking, whether the travel switch is normal, whether the
remote and local switches are in good contact and disconnected, and
whether the break protection switch on the door head is normal;
电动伸缩门故障原因分析:绿灯亮为正常,红灯不亮。如果红灯和绿灯都亮,则是破损物品保护器的故障。如果红灯亮,且三项电不缺,则属于断线物品保护器质量问题;
Analysis of the cause of the malfunction of the electric telescopic
door: the green light is normal, while the red light is not. If both the
red and green lights are on, it is a malfunction of the damaged item
protector. If the red light is on and all three items are in good
condition, it is a quality issue with the disconnected item protector;
处理方法:将断项保护器的常闭触点短路,恢复正常工作。
Solution: Short circuit the normally closed contact of the break item protector and restore normal operation.
现象二:值班人员接触开关进行操作,门的开合方向不对。去当地操作观察,发现门的方向有时对有时错,误认为电机相序有问题,更换新相序后故障仍未*;
Phenomenon 2: The operator on duty contacts the switch for operation,
and the opening and closing direction of the door is incorrect. After
going to the local operation and observation, it was found that the
direction of the door was sometimes right and sometimes wrong, and it
was mistakenly believed that there was a problem with the motor phase
sequence. After replacing the motor with a new phase sequence, the fault
still persists;
