摘　　要：根据目前大型水轮机转轮存在的振动问题，本文用实验方法对HL160转轮尾水管中的水流流态进行了较详细的研究，其中包括尾水管水流压力脉动的测量以及逆流半径的测量。最后对实验结果进行了分析。Presently, there exist many vibration problems in large－scale hydraulic turbines. This paper researches the water flow state in the draft tube of HL160 runner, in which the following contents are included: the velocity field measurement in draft tube, the pressure pulsation measurement as well as the refluent radius measurement. Finally, the experimental results are analyzed.
