1、结构特点
多级离心泵结构复杂，多个叶轮串联，泵体由多节段连接，有平衡轴向力装置。
双级离心泵有两个叶轮，结构介于单级和多级之间，也有轴向力平衡措施。
单级离心泵结构简单，一个叶轮，蜗壳形泵体，轴向力平衡方式简单。
2、工作原理
多级离心泵液体依次通过多个叶轮，能量叠加，扬程高。
双级离心泵液体经过两个叶轮，能量相加，扬程高于单级。
单级离心泵叶轮旋转使液体获能后从出口排出，扬程较低。
3、性能特点
多级离心泵扬程高、流量在高扬程时受限，效率曲线复杂。
双级离心泵扬程适中、流量在高扬程下有优势，效率曲线较平缓。
单级离心泵流量范围广、扬程低，设计工况点附近效率高。
4、应用场景
多级离心泵用于矿山排水、化工高压输送、高层建筑供水。
双级离心泵用于中型建筑消防、工业中间工序液体输送。
单级离心泵用于农业灌溉、低楼层给排水、简单工业水循环。
