風機分類可以按氣體流動的方向，分為離心式、軸流式、斜流式和橫流式等類型。這種風機分類的機器有：離心風機工作時，動力機(主要是電動機)驅動葉輪在蝸形機殼內旋轉，空氣經吸氣口從葉輪中心處吸入。由于排煙管道葉片對氣體的動力作用，氣體壓力和速度得以提高，并在離心力作用下沿著葉道甩向機殼，推薦排煙管道從排氣(qi)口排出。因(yin)氣(qi)體在葉(xie)輪(lun)內的流(liu)動主(zhu)要是在徑向(xiang)平(ping)面(mian)內，故(gu)又(you)稱徑流(liu)風(feng)機(ji)(ji)(ji)。離心(xin)風(feng)機(ji)(ji)(ji)主(zhu)要由葉(xie)輪(lun)和機(ji)(ji)(ji)殼組成，小型(xing)風(feng)機(ji)(ji)(ji)的葉(xie)輪(lun)直接裝在電動機(ji)(ji)(ji)上中、大(da)型(xing)風(feng)機(ji)(ji)(ji)通過聯軸器或皮帶輪(lun)與電動機(ji)(ji)(ji)聯接。離心(xin)風(feng)機(ji)(ji)(ji)一般為單側(ce)(ce)進氣(qi)，用單級葉(xie)輪(lun)；流(liu)量大(da)的可雙(shuang)側(ce)(ce)進氣(qi)，用兩(liang)個背(bei)靠背(bei)的葉(xie)輪(lun)，又(you)稱為雙(shuang)吸式離心(xin)風(feng)機(ji)(ji)(ji)。

1. 技術背景,在(zai)(zai)(zai)焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)接(jie)(jie)(jie)(jie)頭中由于焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)所(suo)引起(qi)的(de)(de)各種(zhong)(zhong)裂(lie)紋(wen)(wen)(wen)，統(tong)稱焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)裂(lie)紋(wen)(wen)(wen)。焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)裂(lie)紋(wen)(wen)(wen)在(zai)(zai)(zai)焊(han)(han)(han)(han)(han)縫金(jin)(jin)屬(shu)與(yu)熱(re)影響(xiang)區(qu)中都可能產(chan)(chan)生(sheng)(sheng)，是焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)凝固冶金(jin)(jin)和固相冶金(jin)(jin)過程中產(chan)(chan)生(sheng)(sheng)為危險的(de)(de)一種(zhong)(zhong)缺陷。焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)結構產(chan)(chan)生(sheng)(sheng)的(de)(de)破壞事故大部分(fen)都是焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)裂(lie)紋(wen)(wen)(wen)所(suo)引起(qi)的(de)(de)。隨(sui)著現代工業的(de)(de)發展(zhan)，焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)結構也趨向大型化(hua)、大容(rong)量和高參數(shu)發展(zhan)。有(you)的(de)(de)在(zai)(zai)(zai)低溫(wen)、腐蝕介質下工作(zuo)，也有(you)的(de)(de)在(zai)(zai)(zai)高溫(wen)高壓下工作(zuo)，廣(guang)泛都用到(dao)各種(zhong)(zhong)高合金(jin)(jin)鋼、不銹鋼，以及種(zhong)(zhong)種(zhong)(zhong)合金(jin)(jin)材(cai)料(liao)。這些(xie)(xie)材(cai)料(liao)往往都對裂(lie)紋(wen)(wen)(wen)十(shi)分(fen)敏感(gan)，而裂(lie)紋(wen)(wen)(wen)卻又是大多重(zhong)大事故的(de)(de)誘因，必須十(shi)分(fen)重(zhong)視。焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)裂(lie)紋(wen)(wen)(wen)種(zhong)(zhong)類繁多，產(chan)(chan)生(sheng)(sheng)的(de)(de)條(tiao)件和原(yuan)因各不相同。有(you)些(xie)(xie)裂(lie)紋(wen)(wen)(wen)在(zai)(zai)(zai)焊(han)(han)(han)(han)(han)后立即產(chan)(chan)生(sheng)(sheng)了，有(you)些(xie)(xie)在(zai)(zai)(zai)焊(han)(han)(han)(han)(han)后延續一定時(shi)間再產(chan)(chan)生(sheng)(sheng)，甚至在(zai)(zai)(zai)使用過程中，在(zai)(zai)(zai)一定的(de)(de)外界條(tiao)件誘發下再產(chan)(chan)生(sheng)(sheng)。裂(lie)紋(wen)(wen)(wen)既出現在(zai)(zai)(zai)焊(han)(han)(han)(han)(han)縫和熱(re)影響(xiang)區(qu)表(biao)面，也產(chan)(chan)生(sheng)(sheng)在(zai)(zai)(zai)其內部。它對焊(han)(han)(han)(han)(han)接(jie)(jie)(jie)(jie)結構的(de)(de)危害有(you)以下幾點。
