       玻璃钢离心通风机蜗壳、蜗舌的形状和尺寸或多或少会影响风机的工作效率。以下小编就来谈谈它们的功能和设计要求:

玻璃钢离心通风机价格

       1、蜗壳

       蜗壳的作用是收集叶轮内甩出的气体,使之流往排气口,并将叶轮上的动压能部分转换成静压能,形成风压力。

       蜗壳形状:对数螺旋线。

       2、蜗舌

       玻璃钢离心通风机蜗壳出口为舌状结构,通常称为蜗舌。蜗舌可以阻止气体在外壳中循环。蜗舌与叶轮外径之间的间隙对噪音有很大影响。间隙小,噪音大;相反,间隙大,噪音降低。蜗舌上的弧形对风机的气动性能影响不大,但对噪音影响很大。弧形半径小,噪音会更大。

       总之,玻璃钢离心通风机的合理设计,对通风除尘和输气效率有较大影响。在使用过程中,除了上面提到的,还有很多其他的注意事项。如果您感兴趣,请访问我们的网站。咨询热线:  0512-82870668
