二、型式

从电动机一侧正视，叶轮顺时针旋转，称为右旋风机，以“右”表示；叶轮逆时针旋转，称为左旋风机，以“左”表示。

风机的出口位置，以机壳的出风口角度表示。机号№2.8～6.3出厂时均做成1种型式，使用单位根据要求，再安装成所需要的位置，订货时不需注明。№8～12.5出风口位置调整范围0～22.5，间隔是45。机号№16、20出风口位置制成固定的三种：0、90、180，不能调整，订货时需注明。

风机的传动方式有A、B、C、D四种。

机号为№2.8～5采用A式传动， №6.3～12.5采用C、D式传动，№16、20采用B式传动。

三、结构

机号为№2.8～5主要由叶轮、机壳、进风口等部分配直联电机而组成。№6.3～20除具有上述部分外，还有传动部分等。

（1）叶轮由12个后倾翼形叶片焊接于曲线型轮盖与平板型轮盘中间。均为钢板制造，并经动、静平衡校正，空气性能良好，效率高、运转平稳。

（2）机壳是用普通钢板焊接而成的蜗形体。机壳做成两种不同型式。№2.8～12.5机壳作成整体，不能拆开。№16、20的机壳制成两开式，沿中分水平面分为两半外，用螺栓连接。

（3）进风口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）传动部分由主轴、轴承箱、滚动轴承、皮带轮或联轴器组成。

四、性能与选择

本样本只给№10样机的无因次性能表及曲线，由该性能表和曲线计算№10以上风机的有因次性能参数。

二、型式

从电动机一侧正视，叶轮顺时针旋转，称为右旋风机，以“右”表示；叶轮逆时针旋转，称为左旋风机，以“左”表示。

风机的传动方式有A、B、C、D四种。

机号为№2.8～5采用A式传动， №6.3～12.5采用C、D式传动，№16、20采用B式传动。

三、结构

机号为№2.8～5主要由叶轮、机壳、进风口等部分配直联电机而组成。№6.3～20除具有上述部分外，还有传动部分等。

（1）叶轮由12个后倾翼形叶片焊接于曲线型轮盖与平板型轮盘中间。均为钢板制造，并经动、静平衡校正，空气性能良好，效率高、运转平稳。

（3）进风口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）传动部分由主轴、轴承箱、滚动轴承、皮带轮或联轴器组成。

四、性能与选择

本样本只给№10样机的无因次性能表及曲线，由该性能表和曲线计算№10以上风机的有因次性能参数。
