軸流風(feng)機是(shi)通(tong)(tong)風(feng)機的一種,通(tong)(tong)風(feng)設(she)(she)備既有(you)送風(feng)設(she)(she)備,也有(you)排風(feng)設(she)(she)備,那么軸流式通(tong)(tong)風(feng)機是(shi)送風(feng)還是(shi)排風(feng)呢?
軸流(liu)(liu)風(feng)(feng)(feng)(feng)機既(ji)有送風(feng)(feng)(feng)(feng)機也(ye)有排風(feng)(feng)(feng)(feng)機,以系(xi)(xi)統為中心,風(feng)(feng)(feng)(feng)機出口(kou)介質流(liu)(liu)往系(xi)(xi)統,那就(jiu)(jiu)是(shi)(shi)送風(feng)(feng)(feng)(feng)機;風(feng)(feng)(feng)(feng)機出口(kou)介質是(shi)(shi)從系(xi)(xi)統中流(liu)(liu)出的,那就(jiu)(jiu)是(shi)(shi)排風(feng)(feng)(feng)(feng)機。一般來說,軸流(liu)(liu)風(feng)(feng)(feng)(feng)機的風(feng)(feng)(feng)(feng)向會(hui)用箭頭標示,根(gen)據葉(xie)片(pian)和旋轉方向就(jiu)(jiu)可以判斷出是(shi)(shi)送風(feng)(feng)(feng)(feng)還(huan)(huan)是(shi)(shi)排風(feng)(feng)(feng)(feng)了;或者在(zai)(zai)軸流(liu)(liu)風(feng)(feng)(feng)(feng)機的出口(kou)處貼一片(pian)紙(zhi)片(pian)(長(chang)度保證(zheng)在(zai)(zai)抽風(feng)(feng)(feng)(feng)時不被(bei)吸進(jin)去干擾風(feng)(feng)(feng)(feng)扇),這樣你站在(zai)(zai)下面就(jiu)(jiu)可以看到風(feng)(feng)(feng)(feng)機開(kai)啟(qi)時到底是(shi)(shi)送風(feng)(feng)(feng)(feng)還(huan)(huan)是(shi)(shi)排風(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(zheng)轉則是風機由隧(sui)道向(xiang)外界大氣排(pai)風,反轉則是風機向(xiang)隧(sui)道內(nei)送風。
隧道(dao)施(shi)工(gong)時(shi),由(you)于炸(zha)藥爆炸(zha)、內(nei)燃(ran)機(ji)的使(shi)用、開挖時(shi)地層中放出(chu)有害氣(qi)體,內(nei)燃(ran)機(ji)和運輸車輛的排氣(qi),洞內(nei)氧氣(qi)太少,這時(shi)就(jiu)(jiu)需要使(shi)用隧道(dao)軸流(liu)(liu)風(feng)(feng)機(ji)向里送風(feng)(feng),從而排除有害氣(qi)體,降低(di)粉塵濃度。隧道(dao)內(nei)比較熱,熱量和廢氣(qi)聚集,或者隧道(dao)內(nei)發生火災時(shi),就(jiu)(jiu)需要使(shi)用軸流(liu)(liu)風(feng)(feng)機(ji)向外排風(feng)(feng)。
