性价比高，交货快


离心风机是根据动能转换为势能的原理，利用高速旋转的叶轮将气体加速，然后减速、改变流向，使动能转换成势能（压力）。在单级离心风机中，气体从轴向进入叶轮，气体流经叶轮时改变成径向，然后进入扩压器。在扩压器中，气体改变了流动方向并且管道断面面积增大使气流减速，这种减速作用将动能转换成压力能。压力增高主要发生在叶轮中，其次发生在扩压过程。在多级离心风机中，用回流器使气流进入下一叶轮，产生更高压力。 直连式离心风机构造 离心式风机由风机蜗壳壳、叶轮和电机等组成。 蜗壳：由环保型镀锌钢板经过模具冲压，成形，点焊等工序制作完成，可为分整体式和半开式； 叶轮：由叶片、曲线型前盘和底盘后盘，经过工装夹具滚铆组成，每叶轮组件经过径向，轴向调到检验，动平衡校正工序，内控标准高于行业标准； 电机部分：该系列风机电机有单相220V，50/60HZ三档调速或者380V，50/60HZ等型号电机，安装方便，灵活等特点。?
