第一個(gè)問題：

　　導(dǎo)軌的深度問題。如果導(dǎo)軌的深度不夠結(jié)構(gòu)與用料不當(dāng)，一旦遇到火災(zāi)，門簾易從導(dǎo)軌脫出，起不到防火作用。

第二個(gè)問題：

　　工業(yè)提升門傳動(dòng)裝置的強(qiáng)度問題，卷簾軸的強(qiáng)度問題卷簾軸強(qiáng)度也是卷簾門的一個(gè)重要參數(shù)，目前這種強(qiáng)度不合格的產(chǎn)品很多，嚴(yán)重影響了工業(yè)提升門的使用。卷簾軸的結(jié)構(gòu)主要指卷簾軸兩端軸頭塞人鋼管內(nèi)的深度及其結(jié)構(gòu)。軸頭塞人深度應(yīng)為軸長(zhǎng)的1／10左右，且要有兩個(gè)法蘭和足夠的焊縫。

第三個(gè)問題：

　　工業(yè)提升門的預(yù)卷問題，工業(yè)提升門特別是鋼質(zhì)工業(yè)提升門門體比較重，所以會(huì)在卷軸上面預(yù)留一圈預(yù)卷。以減少門簾重量對(duì)螺釘處的拉力．防止第一塊簾板破裂。

第四個(gè)問題：

　　防火電控箱及煙感、溫感方面的問題，火災(zāi)溫度控制關(guān)門問題國(guó)標(biāo)規(guī)定．在工業(yè)提升門2米范圍內(nèi)，當(dāng)火災(zāi)發(fā)生．電源中斷．現(xiàn)場(chǎng)無(wú)人操作時(shí)，應(yīng)當(dāng)有火勢(shì)溫度熔斷控制關(guān)門裝置，這個(gè)功能特別對(duì)人員密集場(chǎng)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.
