摘　　要：对符合 API61 0标准的 65Y60型离心油泵输送粘油和清水时的性能进行了实验研究 ,定量地分析了扬程突升现象 ,找出了发生该现象的根源 .研究表明 ,产生扬程突升现象的根源是叶轮和蜗壳表面边界层流态由水力粗糙区向水力光滑区发生了迁移 .The performance of centrifugal oil pump 65Y60 consistent with standard API610 is investigated experimentally by using the media of both the water and oil, respectively and the phenomenon of head sudden-rising is analyzed quatitavely to find the origin of this phenomenon. The investigation shows that the transfer of flow pattern within boundry layer on the surfaces of impeller and volute from hydraulic rough region to hydraulic smooth region is the origin of that phenomenon.
