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、对人体无害的、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。
