4-68型离心通风机

用途

4-68型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。所输送的气体应为不超过80℃的空气和其它不自燃的、对人体、对钢铁材料无腐蚀性的气体。气体内不许含有粘性物质，所含的尘土及硬质颗粒物不大于150mg/m³。

结构特点

风机主要由叶轮、机壳、进风口、传动等部件配直联电动机组成。

（1）叶轮由12片后倾翼形叶片钢板制造，经静动平衡校正，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行体。

（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、带轮或联轴器组成。
