双进风口离心鼓风机
本技术属于鼓风机
,具体涉及一种双进风口离心鼓风机。
技术介绍
鼓风机是一种常见的鼓风设备,传统技术的负机蜗壳都是由罩体和底盖两部分组成,底盖与罩体通过螺钉或螺栓固定连接,其虽然可以满足一般的使用需求,但是传统技术的罩体只有一个进风口,不能根据需要进行调节进风量,故而适用性和实用性受到限制。
技术实现思路
本技术的目的是提供一种结构设置合理且使用稳定性好的双进风口离心鼓风机。实现本技术目的的技术方案是一种双进风口离心鼓风机,包括风机蜗壳和固定在风机蜗壳端面的风机电机,在所述风机蜗壳内有与风机电机主轴相连接的风轮,在所述风机蜗壳上有进风口和出风口,所述风机蜗壳包括底壳和面盖,所述底壳与所述面盖通过螺钉固定连接,在所述面盖的中部有第一进风口,在所述第一进风口内固定有进风网,所述出风口处于底壳的侧边上,所述风机电机固定在底壳的端面中心,在所述底壳的侧边还设有第二进风口,所述第二进风口与出风口对称设置在底壳的侧边上,在所述面盖内还设有进风通道,在所述底壳的内壁上有与所述第二进风口相连通的导风通道,在所述底壳与面盖固定时,所述导风通道与所述进风通道相连 ...
