1、廳門運行時的抖動聲

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

原因：①門上坎導軌沾有塵土形成的塊狀的疙瘩；②地坎槽內有異物，如裝修材料、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：用細砂紙打磨門導軌，去除污垢并用煤油布擦洗，使門導軌潔凈、光滑。剔除地坎槽內的異物。

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、開齊或關齊門時有碰撞聲

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

原因：①上坎安裝偏斜；②廳門視界護板安裝偏斜或距離過小；③廳門或側立柱沒貼防撞膠皮。

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：調整上坎應與地砍同在一個中線上、調整廳門視為界護板的垂直度和距離、廳門和側立柱貼上防撞膠皮塊。

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、廳門被打開時發出“當”的聲音

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

原因：①廳門鉤鎖不水平；②鉤鎖與鎖盒之間的間隙過小；③轎門開門刀與鉤鎖輪之間的間隙過大；④開門機開始開門速度過快。

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：調整鉤鎖的水平度和鉤鎖彈簧、調整鉤鎖與鎖盒之間的間隙、調整開門刀與鉤鎖輪之間的間隙為4-6mm、減小開始開門速度，使開門刀將鉤鎖完全打開后再加速運行。

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、廳門即將關閉時發出“當”的碰撞聲

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

原因：①開門刀與鉤鎖輪之間的間隙過大，廳門過早脫開門刀；②開門機關門末速度過快。

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：調整開門刀與鉤鎖輪的間隙，調整鉤鎖輪之間的距離，使開門刀能夠完全包含著鉤鎖輪。調整關門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.
