1、9-19926型高压离心风机一、特性及应用9/9、9-26型高压离心通风机，一般用于锻冶炉及高压强制通风，并广泛用于输送空气和其他不自燃的、对人体无害的、对钢铁材料无腐蚀性的气体。气体内不含粘性物质，所含尘土及硬质颗粒物不大于150mgm3,气体温度不得超过80七。二、型式9-19.9-26型高压离心通风机均可制成右旋转和左旋转两种型式。从电动机一侧正视，叶轮顺时针旋转称右旋风机，以“右”表示；叶轮逆时针旋转称左旋风机，以“左”表示。风机的出口位置，以机壳的出风口角度表示。“左”、“右”均可制成0、45、90、135、180、225共六种角度。风机的传动方式为A(NO.46.3)和D(NO.7

2、.116)两种。三、结构特点No.46.3主要有叶轮、机壳、进风口等部分配直联电动机组成，No.7.116除具有上述部分外还有传动部分。(1)叶轮：9/9型风机叶片为12片，9-26型风机叶片为16,均属前向弯曲型叶片。叶轮扩压器外缘最高圆周速度不超过140ms叶轮成型后经静、动平衡校正，空气性能优良，效率高，运转平稳可靠。(1)、叶轮：9-19型风机叶片为12片，9-26型风机叶片为16,均属前向弯曲型叶片。叶轮扩压器外缘最高圆周速度不超过140ms叶轮成型后经静、动平衡校正，空气性能优良，效率高，运转平稳可靠。(2)、机壳：机壳是用优质钢板焊接而成的蜗形体。No.2.812.5机壳做成整体

3、，不能拆开。No.16,No.20的机壳制成两开式，沿中分水平面分为两半，用螺栓连接。(3)、进风II：进风I1制成收敛式流线型整体结构，装于风机的侧面：与轴向平行的截面为曲线形状，能使气体顺利进入叶轮，且损失较小。(4)、传动组：传动部分由主轴、轴承箱、联轴器等组成。主轴由优质钢制成。轴承箱整体结构采用球轴承，用轴承润滑脂润滑。四、产品图形五、性能参数表9.19型性能参数表机号No.转速(r/min)风量(m3h)全压(Pa)内效率：%)内功率(kW)所需功率(kW)电动机型号功率(kW)4A29008249701116126435843665364735977073.575.5761.16
