4-79<\/span>、<\/span>4-2X79<\/span>离心通风机中的<\/span>NO3.6-6<\/span>风机主要由叶轮、机壳、进风口等部分配直联电动机组成，<\/span>NO7-20<\/span>除具有上述部分外，还有传动部分等。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>离心通风机叶轮由<\/span>16<\/span>个后倾的圆弧薄板型叶片、曲线型前盘和平板后盘组成，均用钢板制造，并经过动平衡校正，空气性能良好、效率高、噪声低转平衡。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>离心通风机机壳制成二种不同型号，<\/span>NO3-12<\/span>机壳做成整体，不能拆开；<\/span>NO4-20<\/span>的机壳制成两开式，沿中分水平面分为两半，由螺栓连接。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>离心通风机进风口制成整体，装入风机的侧面，与轴向平等的截面为曲线形状，有使气体顺利进入叶轮，且损失较小。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>离心通风机传动部分由主轴、轴承箱、滚动轴承、带轮组成。<\/span><\/p>

4-79<\/span>、<\/span>4-2X79<\/span>离心通风机可用于一般工厂及大型建筑物的室内通风换气，既可用来输入气体，也可用来输出气体。<\/span><\/p>
