卷帘门一般用于车库，仓库中，推拉门则多用于室内设计中，他们两个在本质上有这区别，但是你知道吗？它两个的还有很多其他不同。下面济南卷帘门厂家为您讲解：

Rolling shutter doors are generally used in garages, warehouses, and sliding doors are mostly used in interior design. They are essentially different, but do you know? There are many other differences between the two. Next, Jinan roller shutter door manufacturer will explain to you:

卷帘门和推拉门的主要区别是卷帘门的主轴(俗称束管)。卷帘门是一种将许多活动组合在一起的系列门。它在固定的滑道上上下旋转，以它的顶部为中点，适用于各种店铺。推拉门是基于平衡系统原理实现动态平衡，门体由外力(手动或电动)驱动在轨道系统中运行。适用于各类工厂、物流仓库或特殊高保温车库。和审美要求。

The main difference between roller shutter door and sliding door is the main shaft of roller shutter door (commonly known as bundle tube). The rolling shutter door is a series of doors that combine many activities. It rotates up and down on the fixed slide, taking its top as the midpoint, and is applicable to all kinds of stores. The sliding door realizes dynamic balance based on the principle of balance system, and the door body is driven by external force (manual or electric) to run in the track system. It is applicable to all kinds of factories, logistics warehouses or special high insulation garages. And aesthetic requirements.

一般来说，推拉门的安装工艺比卷帘门高，推拉门要水平上升。原理是门的多关节活动串联，固定在滑轨上。门上方的卷轴是上下旋转的中点，一个特殊的电机用来驱动卷轴的中轴旋转。当达到滚动开关时，电机设置上限和下限位置。自动停止。为确保推拉门的稳定，这一类还将配备稳定保护装置。

Generally speaking, the installation process of sliding door is higher than that of rolling shutter door, and the sliding door should rise horizontally. The principle is that the multi-joint movement of the door is connected in series and fixed on the slide rail. The scroll above the door is the midpoint of up and down rotation. A special motor is used to drive the central axis of the scroll to rotate. When the rolling switch is reached, the motor sets the upper and lower limit positions. Automatic stop. In order to ensure the stability of sliding doors, this category will also be equipped with stability protection devices.

车门底部装有气囊，在关门过程中遇到障碍物能自动倒车全开状态。门底部两端装有叶片式钢丝绳断丝保护器。当提升钢丝绳断裂，门体加速时，该装置能切入导轨，防止门体坠落。当电机装有分离离合器装置并切换到手动操作时，门体可以手动操作。

Airbags are installed at the bottom of the door, which can automatically reverse to the fully open state when encountering obstacles in the process of closing the door. Both ends of the door bottom are equipped with blade-type wire rope break protectors. When the lifting wire rope breaks and the door body accelerates, the device can cut into the guide rail to prevent the door body from falling. When the motor is equipped with a clutch release device and switched to manual operation, the door body can be operated manually.

推拉门还采用扭簧平衡系统，根据门的重载软件计算设计，使平衡达到良好的状态。扭簧采用60Si2MN进口弹簧钢，使用寿命超过80000次。25.4实心圆钢门，带爬升平衡轴，平衡轴设有扭簧断裂保护装置，可防止平衡扭簧断裂时门板掉落；提升滑轮是一个铝制圆柱形滑轮。

The sliding door also adopts the torsion spring balance system, which is calculated and designed according to the heavy load software of the door, so that the balance can reach a good state. The torsion spring is made of 60Si2MN imported spring steel with a service life of more than 80000 times. 25.4 The solid round steel door is equipped with a climbing balance shaft, and the balance shaft is equipped with a torsion spring fracture protection device to prevent the door plate from falling when the balance torsion spring breaks; The lifting pulley is an aluminum cylindrical pulley.
