Rolling shutter doors must be known to all of you. With the development of the times, rolling shutter doors have appeared in large and small streets, from supermarkets and restaurants in villages and towns to large shopping malls in cities and commercial streets. We can see the figure of rolling shutter doors in commercial streets. We may use them for a long time. A series of failures will occur in the rolling shutter doors, and they will not repair them. It is common to repair rolling shutter doors in Jinan What is the cause of the fault? What is the cause? How to solve it? Let's watch the following to find out!

1、马达不能动或速度慢。这种常见故障应由电路断路、电机过热、紧急停止按钮未复位以及负载过重的限位开关引起。解决方法：抽查线路并尝试连接;拆卸并更换烧毁的电机;更换按钮或按几次;拨动限位开关的滑块部分，离开微动开关的接触位置，同时调整微动开关的位置;检查机械部件有无堵塞，如果有，堵塞并障碍物。

1. The motor doesn't work or is slow. This common fault is caused by open circuit, overheated motor, non reset of emergency stop button and overload limit switch. Solutions: spot check the circuit and try to connect it; dismantle and replace the burned motor; replace the button or press several times; move the slider part of the limit switch to leave the contact position of the microswitch, and adjust the position of the microswitch; check whether the mechanical parts are blocked, if any, remove the blockage and remove the obstacles.

2.控制无效。确定故障的位置和原因：接触器的触点被卡住，行程微动开关无效或接触板变形，滑块定位螺钉松动，背板螺钉松动导致背板移位，导致滑块或螺母不能随螺杆的转动而移动到相应的位置，或限位器的传动齿轮损坏，按钮开关的上下键坏死。处理方法：更换接触器;更换微动开关或触点;拧紧滑块螺钉并复位支撑板;更换限制器的传动齿轮;更换按钮。

2. Ineffective control. Determine the location and cause of the fault: the contact of the contactor is stuck, the travel microswitch is invalid or the contact plate is deformed, the slider positioning screw is loose, and the back plate screw is loose, which causes the back plate to shift, resulting in the slider or nut unable to move to the corresponding position with the screw rotation, or the transmission gear of the limiter is damaged, and the up and down keys of the button switch are necrotic. Treatment methods: replace the contactor; replace the microswitch or contact; tighten the slider screw and reset the support plate; replace the transmission gear of the limiter; replace the button.

3.手拉链卡住了。故障原因：圆环链堵塞十字槽;棘爪没有分离棘轮;压链器卡住了。处理方法：理顺圆环链;调节棘爪与压链架相对位置;更换或润滑销轴。

3. The zipper is stuck. Fault causes: the ring chain blocked the cross groove; the pawl did not separate the ratchet; the chain press was stuck. Treatment method: straighten out the ring chain; adjust the relative position between the pawl and the chain holder; replace or lubricate the pin shaft.

4.电机振动或噪音原因：制动盘安装不平衡或内部断裂;制动盘紧固不当;没有轴承润滑油;齿轮啮合不良，接触部位无润滑油或磨损严重;电机电流噪音或振动。处理方法：更换制动盘或重新调整平衡;拧紧制动盘螺母;更换轴承。修理、润滑或更换电机轴的输出齿轮;检查电机，如果损坏，请更换。

4. Causes of motor vibration or noise: unbalanced installation or internal fracture of brake disc; improper fastening of brake disc; no bearing lubricating oil; poor gear meshing, no lubricating oil or serious wear at contact parts; motor current noise or vibration. Treatment method: replace the brake disc or readjust the balance; tighten the brake disc nut; replace the bearing. Repair, lubricate or replace the output gear of the motor shaft; check the motor and replace if damaged.

5.检查电动卷帘门的偏移和螺丝紧固度，检查皮带的紧固度，通过控制器检查电机输出清洗底盘内部的油污和灰尘，通过开关门的宽度、速度和制动等检查电压参数是否正常修复。

5. Check the offset and screw tightness of the electric rolling shutter door, check the tightness of the belt, check the output of the motor through the controller, clean the oil and dust inside the chassis, and check whether the voltage parameters are normally repaired through the width, speed and braking of the door opening and closing.
