用于大型汽轮发电机定子铁芯装拆的组合式600吨油压机

The Combined 600 t Oil Press for Assembling and Dismantling the Stator Cores of Large Turbogenerator

为了在发电厂定期检修时修复和更换大型汽轮发电机定子铁芯零部件,哈尔滨电机厂研制了一台600t油压机,其使用效果良好,具有较大的推广价值。介绍了油压机的结构与动作原理,油泵的造择以及对液压油的要求和使用时的注意事项。确定了拉杆的最小直径、油缸与活塞内外陉及缸简壁厚。核算了缸筒变形和缸底厚度。

In order to repair and replace the parts of stator cores for large turbogenerators in their periodic overhaul on power plants, Harbin Electric Machinery Works developed the oil press, which has larger value to be extended and good use effect. The design and action principle of the press, selection of the oil pumps, as well as the reguirements to hydraulic oils and the point of attention at use are introduced. Minimun diameter of the draw rod, inside and outside diameters of the oil cylinder and the piston, as well as cylinder body wall thickness are determined. The deformation of the cylinder body and thickness of the cylinder bottom are calculated.
