1、離心通風機產品使用說明書用途4-72型離心通風機主要用途是為一般工廠及大型建筑物的室內通風換氣或輸送空氣及其它不自燃、不易爆、不揮發(fā)、對人體無害、對鋼材無腐蝕性之氣體。但輸送的氣體不得含粘性物質，所含塵土及硬質顆粒物不大于150mg/m3，氣體溫度不得超過80。4-72型離心通風機在我國是使用最早的風機，然而也是使用最普通的風機，從高層建筑到地下鐵道，從鍋爐鼓風到廠房換氣，從北部邊疆到南海之濱，從西部高原到東部邊垂，隨處可見。型式從電機一端正視，凡葉輪按順時針方向旋轉者均稱“右旋風機”，以“右”表示，反之則均稱之為“左旋風機”，以左表示。風機的出風口位置以機殼的出風口角度表示，4-72型風機N

2、o2.86在出廠時均做成一種型式，使用單位根據要求再安裝成所需要的位置，訂貨時無須注明。其中：No2.8出風口位置調整范圍是0225，間隔是45；No3.26出風口調整范圍是0225，間隔是22.5；No812出風口調整范圍是0225，間隔是45；No16、20出風口角度制成固定的0、90、180三種，不能調整，訂貨時需注明。風機的傳動方式有A、B、C、D四種：No2.85采用A式傳動，No6既有A式傳動又有C式傳動，No812采用C、D式兩種傳動方式，No1620采用B式傳動。如上述機號、傳動方式、出口角度不能適應您的生產需要，我廠有能力為您改造或設計，直至您滿意為止。結構本風機No2.8A

3、6A主要由葉輪、機殼、進風口、電機等部分組成，No6C和No820除具有上述結構外，還有傳動部分。葉輪由10個后傾機翼型葉片、曲線型輪蓋和平板后盤組成，經動靜平衡校正和超速運轉實驗，效率高，運轉平穩(wěn)可靠，空氣性能良好。機殼用普通鋼板焊接成蝸殼形整體。進風口制成整體結構，裝于風機一側，與軸向平行的截面為曲線形狀，作用是能使氣流順暢進入葉輪，且損失較小。傳動由主軸、軸承箱、滾動軸承、皮帶輪或聯軸器組成。安裝與使用在安裝前首先應準備好安裝所需材料和工具，對風機各部機件進行全面檢查，對葉輪、機殼、主軸和軸承等機件更應特別細致檢查，如發(fā)現損傷、應予修復，然后用煤油清洗軸承箱內部。在進行安裝操作過程中必須

4、注意下列三點：1、 在一些接合面上，為了防止生銹，減少拆卸困難，應涂上一層潤滑油或機械油。2、 在上接合面的螺栓時，如有定位銷釘應先上好銷釘，再擰緊螺栓。3、 檢查機殼內及其它殼體內部，不應有掉入和遺留的工具或雜物。安裝要求：1、 安裝風機時，輸氣管道的重量不應加在機殼上，按圖紙校正進風口與葉輪的軸向和徑向間隙尺寸，且保持軸的水平位置。2、 安裝進風口管道時，可以直接利用進風口本身的螺栓聯接，此時進風口的固定是靠三個沉頭螺釘。3、 出風口被安裝成某一角度時，后盤適當旋轉使標牌在水平位置，其中No8-12角鋼法蘭面應保持水平。4、 安裝No8-12D式風機時，利用千分表和塞尺，測量風機主軸和電機

5、軸的同軸度及聯軸器兩端平行度，兩軸同軸度允差為0.05mm，聯軸器端面平行度允差為0.1mm。5、 風機安裝后，用手試撥轉子，檢查是否有過緊或刮蹭等現象，接線是否正確，其它保險設施是否完善，轉動部分或進出方向是否人已離開，在確保安全后方可進行試運轉。6、 電機安裝后，安裝皮帶輪或聯軸器防護罩，如進氣口處不接管道時，也需加防護網或其它安全裝置（用戶自備），其它部件照圖安裝。由于風機主軸轉數n與內功率N之間有如下關系：=因此在電機容量不改變時，主軸轉速不宜更改，若主軸轉速增大，電機有過負荷被燒之險。風機所配電機功率，系指在特定工況下，正常功耗加上機械損失和應有的儲備量而言，并非出風口全開需功率。如

6、風機出口或入口不接管道或未加外界阻力而進行空轉，則電機亦有被燒之險。為安全起見，應在風機的出口或入口管路中添加閥門，起動時將其關閉，運轉后再將閥門逐漸慢慢開啟，直至規(guī)定工況為止，并注意電機的電流是否超標。維護1、 定期清除風機及輸氣管道內的灰塵、污垢及水等雜質，并防止生銹。2、 風機修理時必須先斷電停機，絕對不允許在運轉中進行，開關應由專人監(jiān)護，以防中途送電。3、 對溫度計及油標的靈敏性應定期檢查。4、 除每次拆修后應更換潤滑油外，還應定期更換潤滑油。5、 每次維修前后均應仔細記錄、清點、核對工具及原材料數量，以防遺忘在風機及管道內部。6、 風機試車時進出口方向十米之內不許站人。7、 安裝、維

7、修及試車時嚴禁無關人員在場圍觀。故障及原因風機的主要故障有：一、 軸承箱振動劇烈。1、 風機軸與電機軸不同心，聯軸器歪斜。2、 機殼或進風口與葉輪摩擦。3、 基礎的剛度不夠或不牢固。4、 葉輪鉚釘松動或輪盤變形。5、 葉輪軸盤與軸松動，聯軸器螺栓松動。6、 機殼與支架、軸承箱與支架、軸承箱與座等聯接螺栓松動。7、 風機進、出口管道安裝不良，產生振動。8、 轉子不平衡。9、 管見過細，風速過快。二、 軸承溫升過高。1、 軸承箱振動劇烈。2、 潤滑脂質量不良、變質或填充過多、含有灰塵、砂粒、污垢等雜質。3、 軸承箱蓋、座聯接螺栓之緊力過大或過小。4、 軸與滾動軸承安裝歪斜，前后兩軸承不同心。5、

8、滾動軸承損壞。三、 電動機電流過大和溫升過高。1、 開車時進氣管道內閘門或節(jié)流閥未關嚴。2、 流量超過規(guī)定值或風管漏氣。3、 風機輸送的氣體中含粘性物質或氣溫太低，氣體密度太大。4、 電機輸入電壓過低或電源單相斷電。5、 聯軸器聯接不正，皮圈過緊或間隙不勻。6、 受軸承箱振動劇烈的影響。7、 受并聯風機工作情況惡化或發(fā)生故障的影響。四、 皮帶滑下兩皮帶輪應該相對應的槽沒對正。五、 皮帶跳動兩皮帶輪距離較近或皮帶過長。訂貨須知訂貨時必須注明風機的機號、風量、壓力、出風口角度、旋轉方向以及電動機型號功率、轉速等。4-72N o2.8A、3.2A、3.6A離心通風機性能與選用件表機號傳動方式轉速r/
