    防火卷帘门安装时存在的容易出现的三大问题:
      Fire shutter installation prone to three problems:
      个问题:导轨的深度问题 如果导轨的深度不够结构与用料不当,一旦遇到火灾,门帘易从导轨脱出,起不到防火作用。
      The first question: guide the depth of the problem If the depth of the guide rail structure and improper material enough, once encounter fire, door curtain from guide out easily, not fire.
      第二个问题: 防火卷帘门传动装置的强度问题 卷帘轴的强度问题卷帘轴强度也是卷帘门的一个重要参数,目前这种强度不合格的产品很多,严重影响了防火卷帘门的使用卷帘轴的结构主要指卷帘轴和两端轴头塞人钢管内的深度及其结构轴头塞人深度应为轴长的110左右,且要有两个法兰和足够的焊缝。
      The strength of the second question: fire shutter drive problem Shutter shaft strength problem shutter shaft strength is also an important parameter of the shutter, the intensity of the current many unqualified products, seriously affected the structure mainly refers to the use of fire shutter shade axis on both ends of the roller shaft and the shaft head, the shaft of the depth and the structure of the steel pipe head depth shall be the axis of around 110, and it takes two to make a flange and enough weld.
      第三个问题:防火卷帘门的预卷问题 防火卷帘门特别是钢质防火卷帘门门体比较重,所以会在卷轴上面预留一圈预卷以减少门帘重量对螺钉处的拉力。防止块帘板破裂。 第四个问题:防火电控箱及烟感、温感方面的问题,火灾温度控制关门问题国标规定。在防火卷帘门2米范围内,当火灾发生。电源中断。现场无人操作时,应当有火势温度熔断控制关门装置,这个功能特别对人员密集场所更显重要。
      The third question: the fire shutter of volume problem Fire shutter, especially the heavy steel anti-fire rolling curtain door, so would have reserved a circle on a scroll in screw of the volume to reduce weight curtain on the pulling force. To prevent the first piece of curtain plate fracture. Fourth question: fire and smoke and temperature electric control issues, the fire temperature control closed questions the nation. Within the scope of the fire shutter 2 meters, when the fire broke out. Power interruption. The unattended operation, it shall have the fire closed fusing temperature control device, this function is especially more important to researchers populated places.
      以上几个问题希望大家引起重视,防火卷帘门如何装置,怎么样才干装置的牢固这也是一个很重要的问题。
      More than a few questions I hope you attention, how fire shutter device, how ability device is firm and this is a very important problem.
