卷簾門在我們的生活中并不少見，現在，它們不僅用于工廠車庫，也用于許多家庭。卷簾門是通過電機的轉動帶動傳動軸轉動，從而實現窗簾片的升降。當它上升時，簾片纏繞在卷軸上，當它下降時，簾片沿著導軌向下滑動。門簾的上升、停止和下降動作是通過遙控器的控制來實現的。還有一個停電手動釋放系統，停電時可以通過手動搖桿提起卷簾門。

Rolling shutter doors are not uncommon in our daily lives. Nowadays, they are not only used in factory garages, but also in many households. The rolling shutter door drives the transmission shaft to rotate through the rotation of the motor, thereby achieving the lifting and lowering of the curtain panels. When it rises, the curtain wraps around the reel, and when it descends, the curtain slides down the guide rail. The lifting, stopping, and lowering actions of the door curtain are controlled by a remote control. There is also a power outage manual release system, which can lift the roller shutter door through a manual joystick during a power outage.

在中，的日常生活中，我們經常會遇到濟南卷簾門不能放下或向上推的問題。造成這種情況的原因大多是兩側滑槽之間的長期摩擦，有些地方可能會損壞，所以拉不是很好。那么就有可能是卷簾門上的彈簧一側斷裂，導致方向錯誤和拉不好山東電動卷簾門是一種工業用門，控制系統是整套快開門的核心。如何確認卷簾門的性能是卷簾門控制系統的配置。因為卷簾門運行速度快，開關頻繁，所以需要穩定的控制系統。沒有好的控制系統，就沒有好的快卷門。  如果出現上述情況，建議您檢查兩側的滑槽，看看是否有損壞，然后拉打開門，看看門的方向是否偏離。如果滑槽或隱藏在滑槽中的門沒有損壞，請潤滑滑槽(因為潤滑脂會持續更長時間)。如果還是不行，有可能是上面的彈簧壞了。

In our daily lives, we often encounter the problem of Jinan roller shutter doors not being able to be lowered or pushed up. The reason for this situation is mostly due to long-term friction between the sliding grooves on both sides, and some areas may be damaged, so the pulling is not very good. So it is possible that one side of the spring on the roller shutter door is broken, resulting in incorrect direction and poor pulling. Shandong electric roller shutter door is an industrial door, and the control system is the core of the entire set of quick opening doors. How to confirm the performance of the roller shutter door is the configuration of the roller shutter door control system. Due to the fast operation speed and frequent opening and closing of rolling shutter doors, a stable control system is required. Without a good control system, there is no good fast rolling door. If the above situation occurs, it is recommended that you first check the sliding grooves on both sides to see if there is any damage, and then pull open the door to see if the direction of the door deviates. If the chute or the door hidden in the chute is not damaged, lubricate the chute (as the grease will last longer). If it still doesn't work, it's possible that the spring on top is broken.

濟南卷簾門的安裝注意事項：

Installation precautions for Jinan rolling shutter doors:

1、檢查洞口是否與產品尺寸一致，防火卷簾門洞口的尺寸，按3 m.

1. Check if the opening is consistent with the product size, and the size of the fireproof rolling shutter door opening should be 3 meters

2.確定安裝的水平線和垂直線，按照設定的尺寸依次安裝。槽口尺寸自上而下應準確一致。對應的槽口應在同一平面上，然后用連接件與孔中的預埋件焊接。

2. Determine the horizontal and vertical lines for installation, and install them in sequence according to the set dimensions. The groove size should be accurate and consistent from top to bottom. The corresponding groove should be on the same plane, and then welded with the connecting piece and the embedded part in the hole.

3.卷簾門應按照手冊的要求安裝。

3. The roller shutter door should be installed according to the requirements of the manual.

4、卷軸、框架板應牢固地安裝在混凝土結構或預埋件上。

4. The scroll and frame plate should be firmly installed on the concrete structure or embedded parts.

5.寬門體需要在中，和滑道之間安裝中柱。中柱的安裝應與地面垂直且牢固，但應易于拆卸和組裝。

5. The wide door body needs to be equipped with a center pillar between the center and the slide. The installation of the center pillar should be perpendicular to the ground and firm, but it should be easy to disassemble and assemble.
