Abstract: Taking world's first 1000MW AP1000 nuclear power turbine manufactured by Harbin Turbine Company and MHI as example, this paper introduced the key factors that have impact on turbine's lubricant selection.Considering its high safety requirement and special working conditions, a nuclear power turbine had high requirements for lubrication compared with a normal steam turbine.This paper discussed different aspects of lubricant performances.Based on in-depth discussion between Harbin Turbine Company and MHI, Shell Turbo J was finally selected as turbine oil for the nuclear power turbine.The process of lubricant selection would provide valuable references to other nuclear projects in the future.

Key words: nuclear power station, 1000MW turbine, turbine lubrication

摘要： 以哈汽-三菱全球第一台百万千瓦AP1000三代核电汽轮机机组为例,讨论了核电汽轮机的润滑选型关键问题。核电汽轮机组因为其高安全性和特殊应用工况,相比普通火电汽轮机有着更高的润滑要求。本文就各润滑性能指标进行了深入探讨。哈汽厂与三菱公司经过深入讨论和反复论证,最终选择了壳牌公司的多宝Turbo J汽轮机油。这对于其他核电机组的润滑油选型有着重大的借鉴意义。
