摘要
分析超临界/超超临界参数火电机组用齿轮调速装置叶轮工作时的受力情况,并利用有限元法和流场提取两种方法获得泵轮所受的应力值,在此基础上对泵轮进行强度计算,给出了泵轮应力分布图,几何变形图。指出了调速装置工作叶轮危险部位所在,为合理化设计大功率齿轮调速装置工作叶轮打下了基础。
The force of working impeller for the supercritical/ultra-supercritical thermal power units gear speed regulating device is analyzed.Using two ways of the finite element method and the flow field extraction,the stress of the pump wheel has been obtained.On the basis of strength calculation,the stress distribution and geometric deformation maps of impeller are given.The dangerous parts of the impeller has been pointed out,laying an important foundation for rationalize design of the working impeller.
