弧形闸门突扩跌坎式通气减蚀研究进展综述

Review on study of aerators with sudden lateral enlargement and bottom drop at taintor gate region

偏心铰弧形闸门门座结构特殊 ,所处水流情况复杂 ,实际运行中大多数是成功的 ,但也有少数发生空蚀破坏。应找出发生空蚀破坏的原因 ,并提出改善措施 ,使工程应用建立在可靠的基础上。

The gate seat of taintor gate with an eccentric hinge is special in construction and the flow condition complex. Most of them in the practical operation were successful,but a few ones as well as their peri regions encountered cavitation damages.The causes of the latter should be found and the improvement measures proposed,so as to make these structures in engineering practice being reliable.
