The finite element analysis software is used to simulate the stress and deformation of the impeller under the

design 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 insufficient strength of the impeller during the actual

operation of the unit; The calculated axial and radial deformations are the values of the gap between the impeller

and the inlet cylinder. It 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 major failures.

零件介绍

PARTS INTRODUCTION

整体铸件齿轮箱-模块化集成装配

Integral casting gearbox-Modular integrated 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

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 integrally 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 secondary installation. The modular design it perfectly solves this problem.
