高压锅炉给水泵的叶轮测绘及设计

北京电力设备总厂对引进的瑞士苏尔寿公司的HPTmk200-320型给水泵生产技术,进行了适合我国国情的国产化改造设计和制造。叶轮测绘采用无损测绘法,仅利用测齿机和分度盘就绘出了叶片型线和流道各部分的尺寸。改造后的该型给水泵运行情况良好,各项性能指标均达到了预期目标。这说明我国完全可以生产出替代进口的产品,为国家节约大量外汇。

Survey and Design of Impellers for HP Boiler Feed Pump

Beijing Power Equipment Works has carded out the retrofitting on design and manufacture of HPTmk200 - 320 model feed pump imported from Swiss according to the local conditions. The survey of the impeller is the non -destructive survey method, which draws out the profile of the blade and sizes of various flow paths with the tooth measuring and dividing disk. After retrofitting the feed pumps are in good operation conditions and all performance indexes have met the predicted targets. This indicates that China is capable to produce the product substituting the imported ones to save a great amount of foreign currency.
