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 desigr conditions. The results of stress analysis provide a scientific basis for checking the strength of the impeller, prevent accidents due to local stress concentration and insufficjent strength ofthe impeller during the actual operation ofthe unit; The calculated axial and radial deformations are the values of the gap between the impeller and the inlet cylinder. lt provides a reference to prevent the impeller and the intake cylinder from scraping each other when the unit is running, resulting in impellerdamage and other major failures.

转子动力设计
ROTOR DYNAMICS DESIGN
专 业设计的转子与轴承，确保能在合理的油膜温度、压力、厚度下运行，有效减少轴承功率消耗。提取大量轴承的刚度和阻尼数据，进行转子动力学分析，保证转子合理的振动值，确保额定转速设定远离临界转速运行，增强整机的稳定性。
Professionally designed rotors and bearings ensure that they can operate under reasonable oil film temperature, pressure and thickness, effectively reducing, bearing power consumption. Extract the stiffness and damping data of a large number of bearings, conduct rotor dynamics analysis, ensure a reasonable vibration value of the rotor, also ensure that the rated speed setting is far away from the critical speed and enhance the stability of the whole machine.
