《工业提升门在安装时常见的问题》

2015-06-01

第一个问题:
  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。
第二个问题:
  工业提升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,严重影响了工业提升门的使用。卷帘轴的结构主要指卷帘轴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1/10左右,且要有两个法兰和足够的焊缝。
第三个问题:
  工业提升门的预卷问题,工业提升门特别是钢质工业提升门门体比较重,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.防止第一块帘板破裂。
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.在工业提升门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 first problem:
  the depth of the problem of guide rail. If the guide deep enough structure and materials properly, once encountered fire, the curtain rail easily from prolapse, not to the fire effect.
Second problems:
  the strength problem of the door drive device of industrial upgrading, an important parameter of rolling shaft strength problem of shutter shaft strength is rolling door, at present a lot of the strength of the unqualified products, serious impact on the use of industrial upgrading door. The rolling shaft structure mainly refers to the depth and structure of rolling curtain shaft ends gudgeon Cypriot in steel pipe. Shaft plug depth should be axis length of 1 / 10, and have two flanges and adequate weld.
Third issues:
  Volume problem of industrial upgrading door pre industrial promote the door especially steel industrial promote the door body is relatively heavy, so reserve a circle above the pre rolled on the reel. In order to reduce the weight of the screw at the curtain pull. Prevent the first piece of the curtain plate rupture.
The fourth question:
  fire control box and the smoke and temperature sensing problems, problems of GB closed fire control temperature. In industrial promote the door within 2 meters, when the fire occurred. A power outage. The scene no operation, should have the fire temperature fuse control closing device, this function is particularly more important on the personnel intensive place.
