针对沿江滨湖地区双向抽水的广泛需要，在分析水力计算的基础上，提出一种新的立式轴流泵出水结构，并辅以适当措施，使立式双向轴流泵装置性能大幅度提高，模型试验最高装置效率达到71%以上；所提出的消涡防涡栅从根本上解决了进水流道内的涡带问题。这两项技术已在工程中成功地推广应用。

Based on analysis and hydraulic computation, a new outlet diffuser of a vertical, axial-flow pump was brought up in this paper, which could meet an extensive requirements for two-way pumping in riverside and littoral areas. With some proper means, the system can greatly promote the pumping performance. The maximum efficiency from the model test was over 71 percent and a vortex eliminating/proventing grid successfully eliminated the vortex in the inlet passage. Both the outlet diffuser and the grid were applied in engineering.
