1，通風風管安裝在支架上，應設托座。2，通風風管如有穿出屋面外部分，應設置防雨罩。3，通風風管采用無法蘭連時，接口處應嚴密牢固。通風風管連接兩平面應平直，不得錯位及扭曲。4，輸送易產生冷凝水的通風風管，安裝應設計坡度。通風風管底部不能有縱向的接縫， 如風管必須有接縫，則應采用密封方式。通風管道安裝完畢后，應進行嚴密性試驗，如風管廠家發現異常情況，通風(feng)管道的制作、安(an)裝、檢驗(yan)和(he)試驗(yan)，是一(yi)個連貫的工程(cheng)，做到安(an)全適用，經濟合理，方(fang)便施(shi)工，確保通風(feng)管道的工程(cheng)質量。

風(feng)(feng)機(ji)(ji)(ji)(ji)分(fen)類可(ke)以按氣(qi)(qi)體流(liu)(liu)(liu)動的(de)(de)方(fang)向，分(fen)為離(li)心(xin)(xin)式(shi)(shi)、軸流(liu)(liu)(liu)式(shi)(shi)、斜流(liu)(liu)(liu)式(shi)(shi)和(he)橫流(liu)(liu)(liu)式(shi)(shi)等類型(xing)。這種風(feng)(feng)機(ji)(ji)(ji)(ji)分(fen)類的(de)(de)機(ji)(ji)(ji)(ji)器有：離(li)心(xin)(xin)風(feng)(feng)機(ji)(ji)(ji)(ji)工作(zuo)時，動力(li)機(ji)(ji)(ji)(ji)(主要是電動機(ji)(ji)(ji)(ji))驅動葉輪(lun)在(zai)蝸形(xing)機(ji)(ji)(ji)(ji)殼(ke)(ke)內旋(xuan)轉，空(kong)氣(qi)(qi)經吸(xi)氣(qi)(qi)口從葉輪(lun)中心(xin)(xin)處吸(xi)入。由于葉片對氣(qi)(qi)體的(de)(de)動力(li)作(zuo)用，氣(qi)(qi)體壓力(li)和(he)速度得以提高，并在(zai)離(li)心(xin)(xin)力(li)作(zuo)用下沿著(zhu)葉道甩向機(ji)(ji)(ji)(ji)殼(ke)(ke)，從排(pai)氣(qi)(qi)口排(pai)出。因氣(qi)(qi)體在(zai)葉輪(lun)內的(de)(de)流(liu)(liu)(liu)動主要是在(zai)徑(jing)(jing)向平面內，故又(you)稱徑(jing)(jing)流(liu)(liu)(liu)風(feng)(feng)機(ji)(ji)(ji)(ji)。離(li)心(xin)(xin)風(feng)(feng)機(ji)(ji)(ji)(ji)主要由葉輪(lun)和(he)機(ji)(ji)(ji)(ji)殼(ke)(ke)組成，小型(xing)風(feng)(feng)機(ji)(ji)(ji)(ji)的(de)(de)葉輪(lun)直接(jie)裝在(zai)電動機(ji)(ji)(ji)(ji)上(shang)中、大型(xing)風(feng)(feng)機(ji)(ji)(ji)(ji)通過聯軸器或皮帶輪(lun)與電動機(ji)(ji)(ji)(ji)聯接(jie)。離(li)心(xin)(xin)風(feng)(feng)機(ji)(ji)(ji)(ji)一(yi)般為單(dan)側進氣(qi)(qi)，用單(dan)級葉輪(lun)；流(liu)(liu)(liu)量大的(de)(de)可(ke)雙(shuang)(shuang)側進氣(qi)(qi)，用兩個背靠背的(de)(de)葉輪(lun)，又(you)稱為雙(shuang)(shuang)吸(xi)式(shi)(shi)離(li)心(xin)(xin)風(feng)(feng)機(ji)(ji)(ji)(ji)。

鑒于軸(zhou)(zhou)流(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)有(you)紊(wen)流(liu)區的(de)性能(neng)特點(dian)，在(zai)(zai)(zai)選型(xing)和(he)使用時，需要注(zhu)意以下兩點(dian)：建(jian)議使用在(zai)(zai)(zai)空曠環境中(zhong),軸(zhou)(zhou)流(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)的(de)輸入(ru)功率隨系(xi)統靜壓的(de)增(zeng)大(da)而(er)增(zeng)大(da)，而(er)在(zai)(zai)(zai)紊(wen)流(liu)區，輸入(ru)功率的(de)增(zeng)大(da)幅度會(hui)(hui)更(geng)大(da)。因此，軸(zhou)(zhou)流(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)一(yi)般多(duo)應用在(zai)(zai)(zai)有(you)較大(da)空曠環境的(de)場合(he)下，可以使其(qi)工(gong)作在(zai)(zai)(zai)靜壓較低(di)的(de)環境下，降低(di)功耗，保(bao)證穩(wen)定(ding)性和(he)壽命。定(ding)期(qi)清(qing)理風(feng)(feng)(feng)(feng)(feng)(feng)道(dao),當軸(zhou)(zhou)流(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)應用在(zai)(zai)(zai)較為封閉的(de)風(feng)(feng)(feng)(feng)(feng)(feng)道(dao)系(xi)統中(zhong)時，長(chang)期(qi)運(yun)行后風(feng)(feng)(feng)(feng)(feng)(feng)道(dao)中(zhong)的(de)積(ji)灰、垃圾逐(zhu)(zhu)漸變(bian)多(duo)，會(hui)(hui)使風(feng)(feng)(feng)(feng)(feng)(feng)道(dao)內的(de)靜壓逐(zhu)(zhu)漸增(zeng)加(jia)(jia)，使得風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)的(de)運(yun)行工(gong)況點(dian)逐(zhu)(zhu)漸左移。這(zhe)不僅會(hui)(hui)降低(di)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)性能(neng)，更(geng)重要的(de)是會(hui)(hui)增(zeng)加(jia)(jia)軸(zhou)(zhou)流(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)進入(ru)紊(wen)流(liu)區的(de)風(feng)(feng)(feng)(feng)(feng)(feng)險。因此必須要定(ding)期(qi)清(qing)理風(feng)(feng)(feng)(feng)(feng)(feng)道(dao)，保(bao)證風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)工(gong)況點(dian)不產生較大(da)偏移。
