4-79<\/span>、<\/span>4-2X79<\/span>離心通風機中的<\/span>NO3.6-6<\/span>風機主要由葉輪、機殼、進風口等部分配直聯電動機組成，<\/span>NO7-20<\/span>除具有上述部分外，還有傳動部分等。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>離心通風機葉輪由<\/span>16<\/span>個后傾的圓弧薄板型葉片、曲線型前盤和平板后盤組成，均用鋼板制造，并經過動平衡校正，空氣性能良好、效率高、噪聲低轉平衡。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>離心通風機機殼制成二種不同型號，<\/span>NO3-12<\/span>機殼做成整體，不能拆開；<\/span>NO4-20<\/span>的機殼制成兩開式，沿中分水平面分為兩半，由螺栓連接。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>離心通風機進風口制成整體，裝入風機的側面，與軸向平等的截面為曲線形狀，有使氣體順利進入葉輪，且損失較小。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>離心通風機傳動部分由主軸、軸承箱、滾動軸承、帶輪組成。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>離心通風機可用于一般工廠及大型建筑物的室內通風換氣，既可用來輸入氣體，也可用來輸出氣體。<\/span><\/p>
