【摘要】：在成熟的离心泵设计基础上,选用优秀的离心泵水力模型作为液力透平的水力模型设计基础。在研究中,试制了4种不同出口宽度的离心泵叶轮,在5000 m~3、开式A级精度水泵试验平台上,采用PSM泵自动检测系统完成了4种不同出口宽度的叶轮作透平运行测试。研究过程中,依据测试得出的结果,提出出口宽度改进方案,不断优化叶轮水力性能,最终得到该型号叶轮最为优秀的出口宽度。研究和测试表明,泵反转作透平运行,通过增大叶轮出口宽度能够提高运行的综合性能,且在此不断增大过程中存在一个最优的出口宽度,最优出口宽度与流量有关。
[Abstract]:On the basis of mature centrifugal pump design, the excellent hydraulic model of centrifugal pump is selected as the basis of hydraulic model design of hydraulic turbine. In the research, four kinds of centrifugal pump impellers with different outlet widths are trial-produced. Four kinds of impellers with different outlet widths have been tested by PSM pump automatic testing system on 5000mm3 open A-class precision pump test platform. In the course of the research, according to the test results, the improved scheme of outlet width has been put forward. The best outlet width of the impeller is obtained by continuously optimizing the hydraulic performance of the impeller. The research and test show that the comprehensive performance of the impeller can be improved by increasing the outlet width of the impeller. In the process of increasing, there is an optimal exit width, and the optimal exit width is related to the flow rate.
