一、前言D300—160注水泵整体叶轮扭曲流道电解抛光新工艺是在研制 D300—160注水泵中提出来的。为了提高注水泵效率及其使用寿命,必须对泵的主要零件叶轮及导翼进行整光加工和表面硬化处理。而整体叶轮流道的扭曲率大,又难以进行机械加工;因此,目前国内大多数厂仍采用手工打光的办法。手工打光,不仅劳动强度大,效率低,成本高;而 First, the preface D300-160 water injection pump overall Impeller Twist flow electrolysis new technology is developed in the development of D300-160 water pump. In order to improve the water pump efficiency and its service life, the main components of the pump impeller and guide wing for finishing and surface hardening treatment. The overall impeller flow channel twist rate, and difficult to mechanical processing; Therefore, most of the domestic plant is still hand-polished approach. Manual lighting, not only labor-intensive, low efficiency, high cost;
