摘要
效率、空蚀和稳定性是水轮机水力性能的三大主要指标,补气对水轮机消除振动和稳定运行、改善空蚀性能和提高效率都有直接影响。本文通过不同水轮机采用不同的补气方式及使用效果进行了详细的分析,供类似型式水轮机的电厂借鉴和参考。
Efficiency, cavitation and stability are key indicators about the performance of hydraulic turbine. The air supply mode has direct influences on eliminating vibration, improving stability, improving cavitation situation and improving efficiency of the turbine. The effects of different air supply mode on different turbines are analyzed and compared in detail in this paper. The results can be the reference for the power plants which have similar turbines.
