叶轮强度分析
Impeller Strength Analysis
运用有限元分析软件，模拟叶轮在设计工况下的应力和变形量情况。应力分析结果为校核叶轮强度提供了科学的依据，防止机组在实际运行时因叶轮局部应力集中、强度不够酿成事故;计算的轴向、径向变形量为叶轮与进气缸间隙的取值提供了参考，防止机组运行时叶轮与进气缸发生相互刮擦，导致叶轮损毁等重大故障的发生。
The finite element analysis software is used to simulate the stress and deformation of the impeller under the designconditions. The results of stress analysis provide a scientific basis for checking the strength ofthe impeller, preventaccidents due to local stress concentration and insuficient strength of the impeller duringthe actual operation oftheunit; The calculated axial and radial deformations are the values of the gap between the impeller and the inletcylinder. lt provides a reference to prevent the impeller and the intake cylinder from scraping each other when theunit is running, resulting in impeller damage and othermajor failures.
