海洋核动力平台用核电汽轮机组供油方式的探讨

Research on Oil Supply Scheme of Lubricating Oil Systemin Floating Nuclear Power Plant

分别对船舶核动力装置滑油系统与陆上核电站滑油系统的特点作了介绍,针对海洋核动力平台的特殊性,配置了两套不同的滑油系统方案:二回路系统集中供油方案和汽轮机自供油方案。前者主要采用由电机驱动的带有自吸功能的三螺杆泵作为主滑油泵的供油方案,而后者则是采用射油器、高压启动油泵、交流电动辅助油泵、直流润滑油泵和汽轮主油泵的供油方案。通过两种不同方案的对比分析得出:集中供油方案具有设备配置数量少、结构紧凑等优点,适合海洋核动力平台滑油系统供油方式。

In this paper,the characteristics of marine nuclear power platform were described,and the oil supply scheme of lubricating oil system in floating and land-based nuclear power plant were introduced in detail.Floating nuclear power plant lubricating oil system uses a motor driven three screw pump with self-suction function as the main oil pump in oil supply program,while the onshore nuclear power plant oil system uses oil injector,high pressure start oil pump,AC electric auxiliary oil pump,DC oil pump and steam-driven main oil pump in the oil supply program.By comparing the two different schemes,the oil supply scheme for oil system at marine nuclear power platform was studied.
