軸流風(feng)(feng)機是(shi)通(tong)風(feng)(feng)機的一(yi)種(zhong),通(tong)風(feng)(feng)設備(bei)既有(you)送(song)風(feng)(feng)設備(bei),也有(you)排(pai)風(feng)(feng)設備(bei),那么軸流式通(tong)風(feng)(feng)機是(shi)送(song)風(feng)(feng)還是(shi)排(pai)風(feng)(feng)呢(ni)?
軸(zhou)流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)既有(you)送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)也有(you)排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji),以(yi)(yi)系統(tong)為(wei)中心(xin),風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)出(chu)(chu)口介(jie)質(zhi)流(liu)(liu)往系統(tong),那(nei)就(jiu)(jiu)是送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji);風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)出(chu)(chu)口介(jie)質(zhi)是從系統(tong)中流(liu)(liu)出(chu)(chu)的(de),那(nei)就(jiu)(jiu)是排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)。一般來說,軸(zhou)流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)的(de)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)向會用箭(jian)頭(tou)標示,根據葉(xie)片(pian)和旋轉方(fang)向就(jiu)(jiu)可(ke)以(yi)(yi)判斷(duan)出(chu)(chu)是送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)還是排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)了;或者在軸(zhou)流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)的(de)出(chu)(chu)口處貼一片(pian)紙片(pian)(長度保證在抽風(feng)(feng)(feng)(feng)(feng)(feng)(feng)時不(bu)被吸進去(qu)干擾風(feng)(feng)(feng)(feng)(feng)(feng)(feng)扇),這(zhe)樣你站在下面就(jiu)(jiu)可(ke)以(yi)(yi)看到風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)開啟時到底是送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)還是排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)了。
二、隧道軸流通風機是向隧道里送風還是向隧道外排風
隧道軸流通風機是隧道內使用的軸流風機,這種軸流風機一般兼具送風和排風兩大功能,隧道軸流風機正轉則是(shi)風機由(you)隧道向(xiang)外界大(da)氣排風,反轉則是(shi)風機向(xiang)隧道內送風。
隧道施工時(shi),由于炸(zha)藥(yao)爆炸(zha)、內燃(ran)機的(de)使(shi)用(yong)、開挖時(shi)地層(ceng)中放出有害(hai)氣體,內燃(ran)機和運輸車輛的(de)排(pai)氣,洞內氧氣太少,這時(shi)就需要使(shi)用(yong)隧道軸(zhou)流風機向里送風,從而(er)排(pai)除有害(hai)氣體,降(jiang)低粉塵濃(nong)度。隧道內比(bi)較(jiao)熱,熱量和廢氣聚集,或者隧道內發生火災(zai)時(shi),就需要使(shi)用(yong)軸(zhou)流風機向外排(pai)風。
