摘要
通过提高泵的转速和单级扬程对传统多级泵进行改进 ,采用的与其它叶轮比转速不同的末级叶轮完全覆盖了原多级泵型谱范围。同时通过对叶轮进行切割 ,减小多级泵的级间扬程 ,方便用户选型 。
By increasing speed and single-state head,the traditional multistage pump was improved.By adopting the end impeller which specific speed is different from others,the model range of the traditional multistage pump was contained completely.By cutting impellers and decreasing the head between stages of the multistage pump,the model choice was easer and the cost of making pumps was reduced.So improving the traditional multistage pump can achieve better economic results.
