为了响应国家政策号召,保障国家能源安全和支持民族工业发展,近年来中国石油组织开展了管道输油泵国产化的相关研究,特别是在2 500 k W级双额定工况管道输油泵研制方面成效显著。管道输油泵国产化经历了以使用国产输油泵为主、引进消化吸收、国产化加速发展3个阶段。国产化管道输油泵为单级双吸水平中开结构,设计了高效水力新模型,能够通过更换叶轮和导叶实现同一壳体两个额定工况功能,同时采用滚动轴承支撑、高性能密封环及集装式机械密封等配套方案。利用同一测试平台、同一标准对3个不同厂家的试制产品进行出厂性能比对测试,结果显示国产化管道输油泵额定效率可以达到89.8%。
In response to the call of national policies, safeguarding national energy security and supporting the development of national industry, in recent years, CNPC has carried out relevant research on the localization of pipeline oil pumps, especially in the development of 2,500 kW double-rated pipeline oil pumps Significant. Domestic pipeline oil pump has gone through the use of domestic-made oil pump, the introduction of digestion and absorption, accelerated localization of three stages. The domestic pipeline oil pump is a single-stage double suction horizontal open structure, a new efficient hydraulic model is designed, and the two rated working conditions of the same shell can be realized by replacing the impeller and guide vanes. At the same time, rolling bearing support, high-performance sealing ring and Cartridge mechanical seals and other ancillary programs. The same test platform, the same standard on the prototype of three different manufacturers of factory performance comparison test results show that the localization of pipeline pump rated efficiency can reach 89.8%.
