离心泵切割定律试验研究及其应用

Experimental Investigations and Application of Cutting-down Law of Centrifugal Pump

讨论了几种切割离心系叶轮的情况，介绍了国内外离心泵切割定律的研究现状。在大量试验的基础上，提出了切割定律的新表达式，并给出了修正系数。论文还示出了新表达式和修正系数的应用实例，对离心泵叶轮的切割有一定的指导意义。

The art-of-state of cutting-down law of centrifugal pump is introduccd here. Based on lots ofexperimental investigation, the paper puts farward with a new formula of cut-down law and its correctingcoefficient. Exemples verify that the formula and coefficient are prectical.
