卷帘门已经在市场中普及很多年了，我们的车库、和工厂、商店的门大多都是使用的卷帘门。下面济南卷帘门厂来给大家讲解下卷帘门使用时部件系统出现问题的原因以及处理。

Curtain doors have been popular in the market for many years. Most of the doors of our garages, factories and stores are rolling doors. Next, Jinan Rolling Door Factory will explain the causes and solutions of the problems of the component system when rolling doors are used.

1、电动机不动或转速慢

1. The motor does not move or the speed is slow

故障原因：一般是线路断路、电机烧损、停止按钮没复位、限位开关动作、负载较大等引起。

Fault cause: generally, it is caused by circuit break, motor burning, stop button not reset, limit switch action, heavy load, etc.

处理方法：检查线路、并接通；更换烧损电机；更换按钮或重复按动几次；拨动限位开关滑块使它脱离微动开关触点，并调整微动开关位置；检查机械部分有无卡阻，若有则卡阻清理障碍物。

Treatment method: check the line and connect it; Replace the burning motor; Replace the button or press it repeatedly several times; Toggle the limit switch slider to separate it from the microswitch contact, and adjust the microswitch position; Check whether the mechanical part is jammed. If so, remove the jamming and clear the obstacles.

2、控制失效

2. Control failure

故障发生的部位及原因：继电器(接触器)触点粘死、行程微动开关失效或触片变形、滑块紧定螺钉松、靠板螺丝松使靠板移位，使滑块或螺母不能随丝杆转动而移动、限位器传动齿轮破损、按钮上、下键卡死。

Parts and causes of failure: relay (contactor) contact is stuck, stroke microswitch is invalid or contact piece is deformed, slider set screw is loose, and backup plate screw is loose, which makes backup plate move, so that slider or nut cannot move with screw rod rotation, limiter transmission gear is damaged, and up and down buttons are stuck.

处理方法：更换继电器(接触器)；更换微动开关或触片；紧定滑块螺钉并使靠板复位；更换限位器传动齿轮；更换按钮。

Handling method: replace the relay (contactor); Replace the microswitch or contact; Tighten the slider screws and reset the backup plate; Replace the limiter transmission gear; Replace the button.

3、手拉链不动

3. The hand zipper does not move

故障原因：环形链条堵住十字槽；棘爪无脱离棘轮；压链架卡死。

Fault cause: the cross groove is blocked by the ring chain; The pawl does not disengage from the ratchet wheel; The chain pressing frame is stuck.

处理方法：理顺环形链条；调整棘爪与压链架相对位置；更换或润滑销轴。

Treatment method: straighten out the ring chain; Adjust the relative position of the pawl and the chain pressing frame; Replace or lubricate the pin shaft.

4、电机振动或噪声较大

4. The motor has large vibration or noise

故障原因：刹车盘不平衡或断裂；刹车盘无紧固；轴承失油或失效；齿轮啮合不顺、失油或磨损严重；电机电流声或振动。

Fault cause: the brake disc is unbalanced or broken; The brake disc is not fastened; Bearing oil loss or failure; Gear engagement is not smooth, oil loss or serious wear; Motor current sound or vibration.

处理方法：更换刹车盘或重新调整平衡；紧固刹车盘螺母；更换轴承；修配电机轴输出端齿轮、润滑或更换；检查电机，如电机坏损则更换。

Treatment method: replace the brake disc or readjust the balance; Tighten the brake disc nut; Replace the bearing; Repair, lubricate or replace the motor shaft output end gear; Check the motor and replace it if it is damaged.
