电动卷帘门关不上怎么办？

What if the electric rolling shutter door can't be closed? Fault causes and treatment methods.

故障原因及处理方法如下：

The fault causes and treatment methods are as follows:

1.电动卷帘门不动或转速慢，原因：线路断开、电机烧坏、停止按钮未复位、限制开关动作、负载过大等。处理方法：检查线路、并接通；更换烧损电机；更换按钮或多次按动；拨动开关的限位滑块与微动开关接触点分开，调节微动开关位置；检查机械部分是否有卡阻，如果有，卡阻障碍。2.控制失效故障的故障位置和原因：继电器(接触器)触点粘合、行程开关失效或触片变形.滑块松开螺钉松开、靠板螺钉松开，靠板移动。滑块或螺母在转动时不能移动、限制器驱动齿轮损坏、按按键。处理方法：更换继电器(接触器)；更换一个微动开关或触片；紧固滑块螺钉，使靠盘复位；更换限位齿轮；更换按钮。

1. The electric rolling shutter door does not move or the speed is slow. The reasons are: the line is disconnected, the motor is burnt out, the stop button is not reset, the limit switch acts, the load is too large, etc. Treatment method: check the line and connect it; Replace the burned motor; Replace the button or press it for many times; The limit slider of the toggle switch is separated from the contact point of the microswitch to adjust the position of the microswitch; Check whether there is jamming in the mechanical part. If so, eliminate the jamming and remove the obstacles. 2. Fault location and cause of control failure: relay (contactor) contact bonding, travel switch failure or contact deformation Loosen the screw of the slider and the screw of the backup plate, and the backup plate moves. The slider or nut cannot move when rotating, the limiter driving gear is damaged, and press the key. Treatment method: replace the relay (contactor); Replace a microswitch or contact piece; Tighten the slider screw to reset the backup plate; Replace the limit gear; Replace the button.

3.手拉链不动故障原因：环形链条堵塞十字槽；棘爪未脱离棘轮；压链架卡死。处理方法：理顺环链；调整棘爪与压链的相对位置；替换销轴或润滑。4.电动机振动或噪声大的原因：制动器不平衡或破裂；制动器未紧固；轴承漏油或失效；齿轮啮合不良.油污或磨损严重；电机电流或振动。处理方法：更换制动盘或重新调整平衡；紧固制动盘螺母；更换轴承；更换电机轴输出.润滑或更换电机；检查电动机，如果电机损坏，则更换。

3. Failure cause of hand zipper immobility: the ring chain blocks the cross groove; The pawl is not separated from the ratchet wheel; The chain pressing frame is stuck. Treatment method: straighten out the chain; Adjust the relative position between the pawl and the pressure chain; Replace the pin or lubricate it. 4. Causes of high motor vibration or noise: unbalanced or broken brake; The brake is not fastened; Oil leakage or failure of bearing; Poor gear engagement Oil stain or serious wear; Motor current or vibration. Treatment method: replace the brake disc or readjust the balance; Tighten the brake disc nut; Replace the bearing; Replace the motor shaft output Lubricate or replace the motor; Check the motor and replace it if it is damaged.

电动卷帘门没有进行日常维修和保养。

The electric rolling shutter door was not repaired and maintained daily.

日常所用损耗还需定期清理维护，以免故障无法及时发现。可能需要安装电控卷闸门结束的一个或多个室内门。在任何时候，操作人员都要注意伸缩门的工作状况，以免发生事故。清扫道岔时要经常清洁，以免杂物堆积影响操作。传动装置每年少要加一次润滑脂，链条要经常加油，检查各部件磨损情况，对磨损严重的机件要及时维修或更换。

The daily losses also need to be cleaned and maintained regularly, so as to prevent the failure from being found in time. It may be necessary to install one or more indoor doors at the end of the electric rolling gate. At any time, operators should pay attention to the working condition of the telescopic door to avoid accidents. The turnout shall be cleaned frequently to avoid the accumulation of sundries affecting the operation. The transmission device shall be greased at least once a year, the chain shall be frequently oiled, the wear of each component shall be checked, and the severely worn parts shall be repaired or replaced in time.
