汽轮发电机边段硅钢冲片胶接工艺的研究

Bonding of the Punching of the Large Turbo generator

为了解决大型汽轮发电机定子硅钢片松动与位移，提高发电机制造质量，作者研制成功３５４２硅钢片胶粘剂，胶接定子边段硅钢片．该胶粘剂为单组份，涂在硅钢片上形成不粘手的未固化硬膜，常温及１２０℃胶接强度均满足使用要求，贮存期大于１年．作者根据现场情况。研究出涂胶、烘干、固化等一系列工艺方法和工艺参数，指导了生产应用．３５４２胶粘剂用于哈尔滨电机厂生产的３台６００ＭＷ定子边段硅钢片胶接，提高了电机产品质量．

The one pack adhesive 3542 was used for bonding the punching of turbo-generator to prevent the losing and moving of the end of stator. The applied process and property was discussed.The Shear strength of adherend is 16MPa when cured at 0C or 120C under the pressure of 1 .5MPa. The process has been applied to the production of 3 turbo-generators of 600MW.
