style="text-indent:25px">葉輪是離心風機的一個相當重要的部件。同時，葉輪本身的尺寸和形狀將直接影響設備的工作性能。通常，葉輪由前蓋，后蓋，葉片和輪轂組成，并且通常焊接和鉚接。葉輪的前蓋有幾種類型，例如平前盤，圓錐形前盤和圓形前盤。扁平前板制造簡單，但對氣流的流動產(chǎn)生不利影響并降低效率。錐形前盤和弧前盤葉輪的生產(chǎn)和加工比較復雜，但工作效率高，葉輪強度好。葉片是葉輪較重要的部分，其出口角度，葉片形狀和葉片數(shù)量對離心風機的運行有很大影響。在離心風機中，由于它們的葉片出口角度不同，它們可以分為三種類型∶前進（前彎），徑向和后(后彎)。在葉輪圓周速度相同的情況下，葉片出口角度越大，產(chǎn)生的壓力越高。因此，兩個相同尺寸和相同速度的離心風機，前彎曲葉輪的壓力高于后彎葉輪的壓力。風機是中國對氣體壓縮和氣體輸送機械的習慣簡稱，通常所說的風機包括通風機，鼓風機，風力發(fā)電機。</p><div
