1. 技術背景(jing),在(zai)(zai)焊(han)接接頭中由于焊(han)接所(suo)(suo)引(yin)起的(de)各種裂(lie)(lie)紋(wen)(wen)，統(tong)稱(cheng)焊(han)接裂(lie)(lie)紋(wen)(wen)。焊(han)接裂(lie)(lie)紋(wen)(wen)在(zai)(zai)焊(han)縫金屬與熱影(ying)(ying)響(xiang)區(qu)中都(dou)可能產(chan)(chan)(chan)生(sheng)(sheng)(sheng)，是(shi)焊(han)接凝固(gu)冶(ye)金和(he)固(gu)相冶(ye)金過(guo)程中產(chan)(chan)(chan)生(sheng)(sheng)(sheng)為危(wei)險(xian)的(de)一種缺陷(xian)。焊(han)接結(jie)(jie)構產(chan)(chan)(chan)生(sheng)(sheng)(sheng)的(de)破壞(huai)事故(gu)大(da)(da)部分都(dou)是(shi)焊(han)接裂(lie)(lie)紋(wen)(wen)所(suo)(suo)引(yin)起的(de)。隨(sui)著(zhu)現(xian)代工業的(de)發展，焊(han)接結(jie)(jie)構也趨向(xiang)大(da)(da)型化、大(da)(da)容量和(he)高(gao)參(can)數發展。有的(de)在(zai)(zai)低(di)溫、腐(fu)蝕介(jie)質下工作，也有的(de)在(zai)(zai)高(gao)溫高(gao)壓下工作，廣泛(fan)都(dou)用到(dao)各種高(gao)合金鋼(gang)、不銹(xiu)鋼(gang)，以及種種合金材料(liao)。這些(xie)材料(liao)往往都(dou)對(dui)裂(lie)(lie)紋(wen)(wen)十分敏(min)感，而裂(lie)(lie)紋(wen)(wen)卻(que)又是(shi)大(da)(da)多重大(da)(da)事故(gu)的(de)誘因，必(bi)須(xu)十分重視。焊(han)接裂(lie)(lie)紋(wen)(wen)種類繁多，產(chan)(chan)(chan)生(sheng)(sheng)(sheng)的(de)條(tiao)件(jian)(jian)和(he)原因各不相同。有些(xie)裂(lie)(lie)紋(wen)(wen)在(zai)(zai)焊(han)后立即產(chan)(chan)(chan)生(sheng)(sheng)(sheng)了(le)，有些(xie)在(zai)(zai)焊(han)后延續一定(ding)時間再產(chan)(chan)(chan)生(sheng)(sheng)(sheng)，甚(shen)至在(zai)(zai)使(shi)用過(guo)程中，在(zai)(zai)一定(ding)的(de)外(wai)界條(tiao)件(jian)(jian)誘發下再產(chan)(chan)(chan)生(sheng)(sheng)(sheng)。裂(lie)(lie)紋(wen)(wen)既(ji)出現(xian)在(zai)(zai)焊(han)縫和(he)熱影(ying)(ying)響(xiang)區(qu)表面，也產(chan)(chan)(chan)生(sheng)(sheng)(sheng)在(zai)(zai)其(qi)內部。它對(dui)焊(han)接結(jie)(jie)構的(de)危(wei)害有以下幾點。

消防排煙風機首先應該滿足溫度和時間的特性，即國家規定280℃/0.5h；其次，在一般環境溫度下，可以保證有效的排煙控制量。此外還要求消防排煙風機能夠進行周期性的實驗，能夠發現其中的不足，并加以改進；可以適用各種通風要求的管道，便于安裝與使用。消防排煙風機的性能優良、耐高溫性能良好、效率高、占地比離心風機少、高溫性能優良。消防排煙風機能在300℃高溫條件下連續運行60分鐘以上，100℃溫度條件下連續20小時不損壞，值得信賴的消防風機應用范圍廣，可根據高級民用建筑的不同要求，采用變速或多速的驅動型式，消防排煙風機廣泛應用于高級民用建筑、烤箱、地下車庫、隧道等場合。消防風機廠家安(an)裝方(fang)便，可直接和(he)墻(qiang)壁(bi)安(an)裝，安(an)裝可采用垂直式(shi)(shi)、水平(ping)式(shi)(shi)或吊裝式(shi)(shi)，很大程(cheng)度(du)上節(jie)省了占地(di)面積。
