一、前言在长叶片中,水蚀几乎是不可避免的。如何采用有效而经济的预防措施便成为长叶片设计中不可缺少的环节之一。本文推荐了一些国内外广为采用的去湿结构,以及在长叶片防水蚀方面的最新科研成果。二、水蚀的评价1.日本三菱公司的评价方法三菱公司在对汽轮机级内水滴的动态过程经过详细的研究后,开发了可靠性较高的评价水蚀的方法。为了评价动叶片的水蚀,
First, the foreword In the long leaves, water erosion is almost inevitable. How to adopt effective and economical preventive measures has become an indispensable part of the long blade design. This article recommends some of the most widely used at home and abroad to dehumidify the structure, as well as in the long leaf waterproof corrosion of the latest scientific research. Second, the evaluation of water erosion Mitsubishi Japan’s evaluation method Mitsubishi Corporation in the turbine-stage water droplets after the dynamic process through a detailed study, the development of a more reliable method of water erosion evaluation. In order to evaluate the water erosion of moving blades,
