摘要
阐述了进水流道引起的泵性能变化和出水流道回收能量作用对泵装置性能的影响。并提出了装置中泵的等扬程加大流量设计方法。
The system characteristics of pumping station are investigatied in detailes. It is found that the pump characteristics are affected by suction tube and the vortex energy can be retrieved by discharge tube. A new pump design method. that is. equivalent-head increase-flow method is given.
