大渡口推薦風管價格

按照氣流運動來進行風機分類的有：1離心風機,氣流進入旋轉的葉片通道，在風管離心力作用下氣體被壓縮并沿著半徑方向流動。2軸流風機氣流軸向進入風機葉輪后，在旋轉葉片的流道中沿著軸線方向流動的風機。相對于離心風機，軸流風機具有流量大、體積小、壓頭低的特點，推薦風管用(yong)于(yu)有灰(hui)塵和腐蝕性氣(qi)體場合(he)時需注意。3斜流(liu)(liu)式(shi)（混流(liu)(liu)式(shi)）風(feng)(feng)(feng)機,在風(feng)(feng)(feng)機的葉輪中，氣(qi)流(liu)(liu)的方向處于(yu)軸(zhou)流(liu)(liu)式(shi)之間(jian)，近似沿(yan)錐流(liu)(liu)動，故可稱為斜流(liu)(liu)式(shi)（混流(liu)(liu)式(shi)）風(feng)(feng)(feng)機。這(zhe)種(zhong)風(feng)(feng)(feng)機的壓力系數比軸(zhou)流(liu)(liu)式(shi)風(feng)(feng)(feng)機高(gao)，而流(liu)(liu)量系數比離(li)心式(shi)風(feng)(feng)(feng)機高(gao)。
