The aerodynamic design of Denel centrifugal compressor uses advanced aerodynamic principles, combined with self-developed efficient modeling software, CFD simulation and other means to ensure the optimal interstage compression ratio allocation and stability reliability: At the same time, combined with the long-temm product verification design experience of the technical development team of Denier, rich impeller database and design software, to ensure the superiority of pneumatic design.
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 analvsis software is used to simulate the stress and deformation of the impeller under the desigr conditions. The results of stress analysis provide a scientific basis for checking the strength of the impeller, preveni accidents due to local stress concentration and insufficientstrength ofthe impeller during the actual operation ofthe unit: The calculated axial and radial defommations are the values of the gap between the impeller and the inlei cylinder. lt provides a reference to prevent the impeller and the intake cylinder from scraping each other when the unit is running, resulting in impeller damage and other majorfailures
