Jinan roller shutter door

1、卷帘门门扇在向内关闭时有碰撞声音传出。

1. When the rolling shutter door leaves close inward, there is a collision sound coming out.

原因：门关闭的速度过快，或者电动机自身发生故障。

Cause: the door closes too fast, or the motor itself fails.

2、卷帘门的开关速度过于缓慢，往往需要等待很久。

2. The opening and closing speed of rolling shutter door is too slow, often need to wait for a long time.

原因：电机内的电压出现异常，连接在电机和快门中间的传动带松弛。或者是固定门和地板发生摩擦的原因。

Cause: the voltage in the motor is abnormal, and the drive belt between the motor and the shutter is loose. Or it's the friction between the fixed door and the floor.

3、卷帘门开关时抖动并有刺耳声音发出。

3. The rolling shutter door vibrates and makes a harsh sound when it is opened and closed.

原因：门移动轨道内有灰尘，阻碍皮带轮运动。

Cause: dust in the moving track of the door hinders the movement of the pulley.

4、门未被操作时，自动开关。

4. When the door is not operated, it will open and close automatically.

原因：操作传感器的故障。或者传感器被其他物体所干扰，不能正常接收命令。

Cause: failure of operation sensor. Or the sensor is disturbed by other objects and cannot receive commands normally.

5、卷帘门不能正常工作，无法启动。

5. The rolling shutter door does not work properly and cannot be started.

原因：可能电动机内线路老化，出现短路。还可能是卷帘门和电动机之间的皮带脱落，不能传输动力。或者门被碎片堵塞，不能升降，电机控制开关有问题，不能正常传输信号。

Cause: the circuit in the motor may be aging and short circuit. It is also possible that the belt between the rolling shutter door and the motor falls off, and the power cannot be transmitted. Or the door is blocked by debris and cannot be lifted or lowered. There is a problem with the motor control switch and the signal can not be transmitted normally.

Jinan rolling shutter door maintenance method:

1、当门无法启动或启动较慢的时候。检查电动机能不能正常工作，如果不能则更换电动机。然后检查机械部分有没有卡住的地方，有的话就排除即可。

1. When the door fails to start or starts slowly. First check whether the motor can work normally, if not, replace the motor. Then check whether the mechanical part is stuck, and if there is any, it can be eliminated.

2、当控制器失效时，我们应该更换电源接触器，然后更换传动齿轮。

2. When the controller fails, we should first replace the power contactor, and then replace the transmission gear.

3、当电动机震动频率过大，噪声过大时。检查轴承是否老化，然后检查滑轮需不需要添加润滑油。

3. When the vibration frequency of the motor is too high and the noise is too large. First check whether the bearing is aged, and then check whether the pulley needs lubricating oil.

4、滑轮和驱动器少每年添加一次润滑油，传动带一年检查一次，定期检查各部件的磨损情况。

4. Add lubricating oil to the pulley and drive at least once a year, and inspect the transmission belt once a year, and regularly check the wear condition of all parts.

想要避免故障，基本的检查和维护工作是要做好的，哪怕一年检查一次也可以，另外如果发现门故障的话，要及时停机，并联系济南卷帘门厂家进行修理，或者问题不大的话，自行处理即可。

If you want to avoid failure, the basic inspection and maintenance work should be done well, even once a year. In addition, if you find the door fault, you should stop the machine in time and contact Jinan rolling shutter door maintenance factory for repair, or if the problem is not big, you can handle it by yourself.
