水轮机的空蚀机理与举措

Cavitation Erosion Mechanism and Measures of Water Turbine

经过几十年的探索研究,空蚀机理已渐渐被人们所认知,但是仍不能从根本上避免这种现象的发生。随着水电事业的发展,研究水轮机的空蚀机理及抗空蚀举措仍有重大的意义。本文就最新的研究理论及当前的水力机械设计水平,简单介绍水轮机的空蚀机理与一些抗空蚀的举措。

After several decades of exploration and research, cavitation erosion mechanism has gradually been recognized by people, but people still can not fundamentally avoid the occurrence of this phenomenon. With the development of the hydropower industry, it is still of great significance to study the cavitation erosion mechanism and the cavitation erosion resistance of the water turbine. In this paper, based on the latest research theory and the current level of hydraulic machinery design, a brief introduction of the cavitation erosion mechanism of water turbine and some anti-cavitation measures are put forward.
