卷帘门门扇开关慢一般有一下几点原因:

There are generally several reasons for the slow opening and closing of the rolling shutter door leaf:

1、控制器速度调整太慢。只需要在电机上把速度设置到满意的位置即可。如果已经调节到较大的行程速度仍然比较慢，则可能是电机的五金件老化，增加了门体运行时的摩擦力。

1. The controller speed adjustment is too slow. Just set the speed to the desired position on the motor. If the travel speed has been adjusted to a larger range and is still relatively slow, it may be due to the aging of the hardware components of the motor, which increases the friction force during the operation of the door body.

2、电压失常。

2. Voltage malfunction.

3、皮带或许过火松动。

3. The belt may be too hot and loose.

4、止动轮与轨道抵触。

4. The stop wheel collides with the track.

5、活动门扇或许与导轨或与固定门扇发生抵触或与地板发生抵触。而卷帘门门扇开关时不停抖动可能由于地下导轨或止摆器有障碍物或磨损的原因。

5. The movable door leaf may conflict with the guide rail or with the fixed door leaf or with the floor. The continuous shaking of the rolling shutter door leaf during opening and closing may be due to obstacles or wear on the underground guide rail or swing stop.
