Examples
- Cavitations of water pump and its installation level
离心式水泵的汽蚀与安装高度 - But the general used ski - jump energy dissipation scheme often causes a series of insurmountable difficulties , such as fogging , cavitations demolition , and bank scouring
而常规的挑流消能方案，又常出现象雾化、空蚀破坏、岸坡冲刷等较难以克服的问题。 - This paper presents a design method of propeller blade section operating in non - uniform flow field and an idea of equivalent operating curve with unchanged cavitations characteristic on blade section , the method for selecting the curve is set up
摘要给出了非均匀流场中螺旋桨桨叶剖面的设计方法，提出了保持剖面空泡特征不变的等效运转曲线的思想，并创建了等效运转曲线的确定方法。 - Cavitations in foreign hydraulic turbines appear in clear water condition , so its destructive extent is not far more serious than in yellow river in our country . stronger stiffness and more agility are required for special - purpose robot for hydraulic turbine repair used in our country , especially robot for polishing after weld . foreign robot for hydraulic turbine repair could not satisfy our working require , so we develop special - purpose robot system that is used to polish and weld repair cavitated flow path surfaces of hydraulic turbines on all locations
国外水电站的水轮机汽蚀是在清水条件下产生的，其破坏程度远不及我国黄河等水域严重，用于我国水轮机修复工作的专用机器人，特别是补焊后承担打磨的机器人，要求有更强的刚度和更大的灵活性，国外水轮机修复机器人满足不了我国水轮机修复工作要求，因此我们开发了用于在机坑内对水轮机空蚀磨损破坏表面进行修复的“水轮机修复专用机器人” 。 - Based on the comparison made among the characteristics of different kinds of the blade materials , the relationship between the material characters and the flow attack angle is explained , and then the breakage mechanism of the combined effects from both the clearance - cavitations and the erosion of leakage flow are expounded comprehensively
通过对不同材料的特性比较，解释了材料特性与冲角之间的关系，综合阐述了泄漏流动所引起叶片正面头部空蚀与磨损联合作用产生破坏的机理。
