style="text-indent:25px">從主要領(lǐng)域需求結(jié)構(gòu)預測：一般通風換氣風機(一般為中小型離心和軸流通風機)使用較普遍，需求量較多，制造廠商也較多?？傮w講，這類產(chǎn)品供大于求。特殊用途風機(包括防腐風機、高溫風機、耐磨風機、消防排煙風機等)需求量雖然不很大，但因作業(yè)環(huán)境特殊，需要區(qū)別對待，因為主要材質(zhì)要求較特殊。羅茨鼓風機的較大特點是當壓力在允許范圍內(nèi)調(diào)節(jié)時，流量變化甚微，壓力選擇范圍寬，具有強制輸氣特征，主要缺點是噪聲較大。通過引進技術(shù)、合資及自行開發(fā)等，我國已推出噪聲較低的三葉羅茨鼓風機，頗受用戶歡迎，市場前景較好。透平壓縮機(包括離心壓縮機、軸流壓縮機和軸流-離心復合式壓縮機)是重大工程成套裝置重要設(shè)備，在國民經(jīng)濟中起著重要作用。對透平壓縮機的性能要求既要壓力高，又要流量大。隨著成套裝置大型化，要求透平壓縮機參數(shù)越來越高。如高爐冶煉裝置、大型煤化工裝置、大型化肥裝置、大型乙烯裝置、大型空分裝置、天然氣管線輸送裝置及油田注氣裝置等。這類產(chǎn)品需求量占風機總量很少，但由于重要，以及結(jié)構(gòu)復雜，制造周期長，技術(shù)含量高，因此，有比較好的經(jīng)濟效益和社會效益。透平壓縮機制造水平表示了風機行業(yè)整體水平。風機用戶主要追求的是高效率、低噪聲、長壽命，且價格便宜。蘇州屋頂風機維修</p><p style="text-indent:25px">按氣體流動的方向：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（混流式）和橫流式等類型。蘇州屋頂風機維修</p><p style="text-indent:25px">高溫離心風機主要應(yīng)用于干燥行業(yè)、鍋爐行業(yè)、清洗行業(yè)、涂裝行業(yè)、食品烘干行業(yè)，風冷型使用溫度在230℃之內(nèi)，水冷型使用溫度在280℃之內(nèi)。耐高溫離心風機輸送的氣體為空氣或其他不自燃、不自爆、無纏繞性、對人體無害、對鋼鐵材料無腐蝕之氣體。也可作為各行業(yè)輸送無腐蝕性、不自燃、不含粘性物質(zhì)的熱氣、蒸氣、煙氣。其它性能相近者亦可選用，但輸送介質(zhì)的溫度不得超過其額定溫度范圍。氣體內(nèi)不許有粘性物質(zhì)，所含的塵土及硬質(zhì)顆粒不大于150mg/m3。如含塵土量大，在耐高溫離心風機前必須加裝準備就緒不低于85%的除塵裝置，降低進入耐高溫離心風機的煙氣含塵量，以利提高耐高溫離心風機壽命。蘇州屋頂風機維修</p></p><br
