1. 技術背景,在(zai)焊(han)接(jie)接(jie)頭中(zhong)(zhong)由于焊(han)接(jie)所引起的(de)各(ge)種(zhong)(zhong)裂(lie)(lie)紋，統稱焊(han)接(jie)裂(lie)(lie)紋。焊(han)接(jie)裂(lie)(lie)紋在(zai)焊(han)縫金(jin)屬與熱(re)影響區中(zhong)(zhong)都可能產(chan)(chan)生，是(shi)(shi)焊(han)接(jie)凝固冶金(jin)和(he)固相(xiang)(xiang)冶金(jin)過程(cheng)中(zhong)(zhong)產(chan)(chan)生為危(wei)險的(de)一種(zhong)(zhong)缺陷。焊(han)接(jie)結構產(chan)(chan)生的(de)破壞事(shi)故大(da)部分(fen)都是(shi)(shi)焊(han)接(jie)裂(lie)(lie)紋所引起的(de)。隨著現(xian)(xian)代工(gong)(gong)業的(de)發(fa)(fa)展(zhan)(zhan)，焊(han)接(jie)結構也趨向大(da)型(xing)化、大(da)容量和(he)高(gao)參數發(fa)(fa)展(zhan)(zhan)。有的(de)在(zai)低溫、腐蝕介質(zhi)下(xia)(xia)工(gong)(gong)作(zuo)，也有的(de)在(zai)高(gao)溫高(gao)壓下(xia)(xia)工(gong)(gong)作(zuo)，廣(guang)泛都用(yong)到各(ge)種(zhong)(zhong)高(gao)合(he)金(jin)鋼(gang)、不(bu)銹鋼(gang)，以(yi)及(ji)種(zhong)(zhong)種(zhong)(zhong)合(he)金(jin)材料。這些(xie)(xie)材料往往都對(dui)裂(lie)(lie)紋十(shi)分(fen)敏感(gan)，而裂(lie)(lie)紋卻又是(shi)(shi)大(da)多(duo)重大(da)事(shi)故的(de)誘因，必須十(shi)分(fen)重視。焊(han)接(jie)裂(lie)(lie)紋種(zhong)(zhong)類繁(fan)多(duo)，產(chan)(chan)生的(de)條件(jian)和(he)原因各(ge)不(bu)相(xiang)(xiang)同。有些(xie)(xie)裂(lie)(lie)紋在(zai)焊(han)后立(li)即產(chan)(chan)生了，有些(xie)(xie)在(zai)焊(han)后延續一定(ding)時間(jian)再產(chan)(chan)生，甚至在(zai)使用(yong)過程(cheng)中(zhong)(zhong)，在(zai)一定(ding)的(de)外(wai)界條件(jian)誘發(fa)(fa)下(xia)(xia)再產(chan)(chan)生。裂(lie)(lie)紋既出現(xian)(xian)在(zai)焊(han)縫和(he)熱(re)影響區表(biao)面，也產(chan)(chan)生在(zai)其(qi)內部。它對(dui)焊(han)接(jie)結構的(de)危(wei)害有以(yi)下(xia)(xia)幾點(dian)。

風機廣泛地應用于各個工業部門，一般講，離心式風機適用于小流量、高壓力的場所，而軸流式風機則常用于大流量、低壓力的情況，不銹鋼通風管道價格應根據不同的情況選有不同的風機分類。1鍋爐用風機,鍋爐用風機根據鍋爐的規格可選用離心式或軸流式。又按不銹鋼通風管道它的作用(yong)分為鍋(guo)爐風機(ji)—向鍋(guo)爐內(nei)輸送空(kong)氣(qi)(qi)；鍋(guo)爐引風機(ji)把鍋(guo)爐內(nei)的煙氣(qi)(qi)抽走。2通風換氣(qi)(qi)用(yong)風機(ji),這類(lei)風機(ji)一般是供工廠(chang)及(ji)各種(zhong)建(jian)筑物通風換氣(qi)(qi)及(ji)采(cai)暖通風用(yong)，要(yao)求壓力不高，但噪聲要(yao)求要(yao)低，可采(cai)用(yong)離心式或軸流式風機(ji)。
