《工業提升門在安裝時常見的問題》 

發布時間:2015/05/31

第一個問題:
  導軌的深度問題。如果導軌的深度不夠結構與用料不當,一旦遇到火災,門簾易從導軌脫出,起不到防火作用。
第二個問題:
  工業提升門傳動裝置的強度問題,卷簾軸的強度問題卷簾軸強度也是卷簾門的一個重要參數,目前這種強度不合格的產品很多,嚴重影響了工業提升門的使用。卷簾軸的結構主要指卷簾軸兩端軸頭塞人鋼管內的深度及其結構。軸頭塞人深度應為軸長的1/10左右,且要有兩個法蘭和足夠的焊縫。
第三個問題:
  工業提升門的預卷問題,工業提升門特別是鋼質工業提升門門體比較重,所以會在卷軸上面預留一圈預卷。以減少門簾重量對螺釘處的拉力.防止第一塊簾板破裂。
第四個問題:
  防火電控箱及煙感、溫感方面的問題,火災溫度控制關門問題國標規定.在工業提升門2米范圍內,當火災發生.電源中斷.現場無人操作時,應當有火勢溫度熔斷控制關門裝置,這個功能特別對人員密集場所更顯重要。
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.
