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.

整体铸件齿轮箱-模块化集成装配
Integral casting gearbox-Modularintegrated assembly
水平剖分式齿轮箱与各级蜗壳一体铸造，冷却器箱体整体铸造，模块化设计。与焊接齿轮箱分体式结构相比，主机机构强度更高、加工面更少、运行更可靠，各级蜗壳与齿轮箱体无装配误差、无变形、噪音低、振动小。与整体铸造相比，加工、装配、运输、现场安装、维护更加简便，在主机需要返厂大修的情况下，整体铸件需要更大起吊设备且破坏安装基础导致二次安装，而模块化的设计则完美解决这一问题。
The horizontally split gearbox is integrally cast with the volutes at all stages, and the cooler box is integralh cast with a modular design. Compared with the split structure of the welded gearbox, the main engine mechanism has higher strength, fewer processing surfaces, and more reliable operation. There is no assembly error, no deformation, low noise and low vibration between the volute and the gear box at all stages. Compared with integral casting, processing, assembly, transportation, on-site installation and maintenance are simpler. When the main engine needs to be returned to the factory for overhaul, the integral casting requires larger lifting equipment and destroys the installation foundation. resulting in secondaryinstallation, The modular desien it pertectily solves this problem.
