卷帘门采用优异铝合金材料和专用设备制作，中间填充聚氨酯泡沫材料，赢得了众多用户的青睐。装有防撬装置，关闭后不能从外面打开。经久耐用，防盗性能好，让你的生活更可靠。下面济南卷帘门厂讲解一下卷帘门的三大运行系统吧。

The roller shutter door is made of excellent aluminum alloy material and special equipment, and filled with polyurethane foam material in the middle, which has won the favor of many users. It is equipped with anti-prying device and cannot be opened from outside after being closed. Durable, good anti-theft performance, make your life more reliable. Next, Jinan Rolling Door Factory will explain the three major operating systems of rolling door.

一、承重系统软件

1、 Load bearing system software

其承重系统软件分为上承重和下承重，下承重系统软件由下轨和下承重轮组成。下轨和下承重轮需要有足够的压缩强度这是因为卷帘门的所有净重都是根据下承重轮传递到下轨的，而下轨和下承重轮也要承受部分风荷载。下轨一般由轻轨站铺设，铺装时，左右轨道的轴线相互平行，以保证卷帘门的稳定运行。根据轻轨站上的旋转，下承重轮可以推动车门一起工作，然后保持车门打开和关闭。

Its bearing system software is divided into upper bearing and lower bearing, and the lower bearing system software is composed of lower rail and lower bearing wheel. The lower rail and lower bearing wheel need to have sufficient compression strength because all the net weight of the roller shutter door is transferred to the lower rail according to the lower bearing wheel, and the lower rail and lower bearing wheel also have to bear part of the wind load. The lower rail is generally laid by the light rail station. When paving, the axes of the left and right rails are parallel to each other to ensure the stable operation of the roller shutter door. According to the rotation on the light rail station, the lower bearing wheel can push the door to work together, and then keep the door open and closed.

二、驱动器系统软件

2、 Drive system software

驱动软件是卷帘门的重要驱动力。它利用电动机立即推动链轮链，再由链轮链和传动链推动门体的下承重轮弹出，超过了开关门体的目的。此外，驱动器组织应设计一个技术和离合器。如果有些家用电器停电或故障，人们可以选择手动方法来开关电源的闸门。

The driving software is an important driving force for the roller shutter door. It uses the motor to immediately push the sprocket chain, and then the sprocket chain and drive chain to push the lower bearing wheel of the door body to pop up, which exceeds the purpose of opening and closing the door body. In addition, the drive organization should design a technology and clutch. In case of power failure or failure of some household appliances, people can choose the manual method to switch the power supply gate.

三、密封系统软件

3、 Sealing system software

卷帘门的门体、门框、门体和门体中间要有很好的密封效果，密封原料大部分是硫化橡胶和聚酯刷。而且门体的侧封也要密封完好。当卷帘门的门体适时时，密封系统软件会与另一门体或墙体加强件重叠，防止过程重叠碰到门体，造成门体结构划伤。

The door body, door frame, door body and the middle of the door body of the rolling shutter door should have a good sealing effect. Most of the sealing materials are vulcanized rubber and polyester brush. And the side seal of the door body should also be sealed well. When the door body of the rolling shutter door is in good time, the sealing system software will overlap with another door body or wall reinforcement to prevent the process from overlapping and touching the door body, causing scratch on the door body structure.

与其他门窗相比，卷帘门的卷帘开启时会将门帘卷铝合金盖上部，不仅节省了房屋顶部的占用空间，还节省了室内空间，不会将灰尘、雪、雨等杂物带入房屋。还有什么卷帘门的相关事项要咨询，就来我们网站http://www.jnhsjlm.com看看吧！

Compared with other doors and windows, when the rolling shutter of the rolling shutter door is opened, it will roll the door curtain to the upper part of the aluminum alloy cover, which not only saves the occupied space on the top of the house, but also saves the indoor space, and will not bring dust, snow, rain and other debris into the house.
