                                                    4-72型離心風機
                                                    4-72型離心通風機
                                                      一、用途
                                                      4-72型離心通風機(以下簡稱風機)可作為一般通風換氣用,其使用條件如下:
                                                      1、應用場所:作為一般工廠及大建筑物的室內通風換氣,既可作用輸入氣體,也可作用輸出氣體。
                                                      2、輸送氣體種類:空氣和其他不自然的,對人體無害的;對鋼鐵材料無腐蝕性的氣體。
                                                      3、氣體內的雜質:氣體內不許有粘性物質,所含的塵土及硬質顆粒物不大于150mg/m 3。
                                                      4、氣體內的溫度:不得超過80℃。
                                                      二、風機的型式
                                                      風機可制成右旋轉和左旋轉二種型式,從電動機一端正視,葉輪按順時針方向旋轉,稱為右旋轉風機,以“右”表示,按逆時針旋轉,稱為左旋轉風機,以“左”表示。
                                                      風機的出口位置,以機殼的出風口角度表示,4-72型風機NO2.8-12在出廠時均作成1種型式,使用單位根據要求再安裝所需要的位置,訂貨時不要注明,NO2.8出風口位置調整范圍0 0 -255 0,間隔是45 0,NO3.2-5出風口位置調整范圍0 0 -255 0,間隔是22.5 0,NO6-12出風口位置調整范圍0 0 -180 0,除NO12間隙15 0外,其他三種風機間隔為22.5 0,NO16.20出風口位置制成固定三種,0 0、90 0、180 0不能調整,訂貨時需注明。
                                                      風機的傳動方式,計有A、B、C、D四種,A式表示無軸承箱裝置,以電動機直聯傳動;B表示懸臂支承裝置,皮帶傳動,皮帶輪在軸承中間;C式青示懸臂支承裝置,皮帶傳動,皮帶輪在軸承外側;D式表示懸臂支承裝置,用聯軸器聯接傳動。
                                                      4-72型風機中,NO2.8-5采用A式傳動;NO6-12采用滾動軸承支承,分為C式和D式兩種傳動,NO16-20采用滾動軸承支承,為B式傳動型式。
                                                      三、風機的結構
                                                      4-72型風機中的NO2.8-5風機主要由葉輪、機殼、進風口等部分配置聯電機而組成。NO6-20除具有上述部分外,還有傳動部分等。
                                                      1、葉輪有十個后傾的機翼型葉片,曲線型前盤和平板后盤組成。均用鋼板制造,并經過動,靜平衡校正,空氣性能良好,效率高,運轉平穩。
                                                      2、機殼制成三種不同型式,NO2.8-12機殼作為整體,不能拆開。NO16-20的機殼制成三開式,除沿中分水平面分為二半外,上半部再沿中心線垂直分為二半,用螺栓連接。
                                                      3、進風口制成整體,裝于風機的側面,與軸向平行的截面為曲線形狀,能使氣體順利進入葉輪,且損失較小。
                                                      4、傳動部分由主軸、軸承箱,滾動軸輪,皮帶輪或聯軸器組成。
