1、厅门运行时的抖动声

1. The shaking sound during the operation of the hall door

原因：①门上坎导轨沾有尘土形成的块状的疙瘩；②地坎槽内有异物，如装修材料、生活垃圾等。

Reason: ① Block like lumps formed by dust on the guide rail of the door sill; ② There are foreign objects inside the trench, such as decoration materials, household waste, etc.

方法：用细砂纸打磨门导轨，去除污垢并用煤油布擦洗，使门导轨洁净、光滑。剔除地坎槽内的异物。

Solution: Use fine sandpaper to polish the door guide rail, remove dirt, and scrub with a kerosene cloth to make the door guide rail clean and smooth. Remove foreign objects from the sill groove.

2、开齐或关齐门时有碰撞声

2. There is a collision sound when opening or closing the door completely

原因：①上坎安装偏斜；②厅门视界护板安装偏斜或距离过小；③厅门或侧立柱没贴防撞胶皮。

Reason: ① The installation of the upper ridge is skewed; ② The installation of the hall door sight guard is skewed or the distance is too small; ③ The hall door or side pillars are not covered with anti-collision rubber.

方法：调整上坎应与地砍同在一个中线上、调整厅门视为界护板的垂直度和距离、厅门和侧立柱贴上防撞胶皮块。

Solution: Adjust the upper ridge to be on the same centerline as the ground cut, adjust the verticality and distance of the hall door as the boundary protection plate, and apply anti-collision rubber blocks to the hall door and side pillars.

3、厅门被打开时发出“当”的声音

3. The hall door makes a "clang" sound when opened

原因：①厅门钩锁不水平；②钩锁与锁盒之间的间隙过小；③轿门开门刀与钩锁轮之间的间隙过大；④开门机开始开门速度过快。

Reason: ① The hook lock of the hall door is not level; ② The gap between the hook lock and the lock box is too small; ③ The gap between the car door opener and the hook locking wheel is too large; ④ The door opener starts opening too quickly.

方法：调整钩锁的水平度和钩锁弹簧、调整钩锁与锁盒之间的间隙、调整开门刀与钩锁轮之间的间隙为4-6mm、减小开始开门速度，使开门刀将钩锁完全打开后再加速运行。

Solution: Adjust the levelness of the hook lock and the hook lock spring, adjust the gap between the hook lock and the lock box, adjust the gap between the door opener and the hook lock wheel to 4-6 mm, reduce the starting speed of opening the door, so that the door opener fully opens the hook lock before accelerating the operation.

4、厅门即将关闭时发出“当”的碰撞声

4. When the hall door is about to close, it makes a clanging sound

原因：①开门刀与钩锁轮之间的间隙过大，厅门过早脱开门刀；②开门机关门末速度过快。

Reason: ① The gap between the door opener and the hook lock wheel is too large, causing the hall door to detach the door opener too early; ② The speed of the door opening mechanism is too fast.

方法：调整开门刀与钩锁轮的间隙，调整钩锁轮之间的距离，使开门刀能够完全包含着钩锁轮。调整关门末速度或扭矩小一些。

Solution: Adjust the gap between the door opener and the hook locking wheel, and adjust the distance between the hook locking wheel so that the door opener can fully contain the hook locking wheel. Adjust the closing speed or torque to be lower.
