The phenomenon of oil spilling and oil spilling in the lubricating oil system of the water guide bearing occurs frequently during the operation of the pumped-storage unit, which significantly affects the safety and stability of the unit and the operating environment of the power station. With the help of CFD numerical simulation technology and VOF multiphase flow simulation method, the dynamic characteristics of water guide bearing lubricating oil system in the multi-oil level working condition under the pumping mode of the pumped-storage unit were explored. The research results show that under the low oil level condition, the system flow cycle is formed faster, the flow state is stable and the oil level is low during the transition process, so the oil rejection phenomenon is milder, but too low oil level may lead to unfavorable control of oil temperature; Under the condition of high oil level, the phenomenon of oil spillage in the early stage of the flow mostly occurs near the side of the Pitot tube of the rotating oil basin, and it mostly occurs on the other side of the Pitot tube in the later stage of the flow. Compared with the traditional method of increasing the diameter of the Pitot tube, the method of optimizing the outer wall of the Pitot tube is more effective in suppressing the phenomenon of oil spillage. The results provide a theoretical basis for exploring the causes of the oil spill phenomenon in the water guide bearing lubricating oil system of the pumped-storage unit and the optimization of the oil slinger.

水导轴承润滑油系统甩油溢油现象在抽蓄机组运行中频发,显著影响了机组的安全稳定性和电站的运行环境。借助CFD数值模拟技术和VOF多相流模拟方法,探究了抽蓄机组抽水模式下水导轴承润滑油系统在多油位工况内部流动的动态特性。结果表明,低油位工况下系统流动循环形成更快,过渡过程流态稳定且油位较低,因此甩油现象更轻微,但过低油位可能导致不利于油温的控制;高油位工况下,流动前期甩油溢油现象多发生于旋转油盆毕托管侧附近,流动后期多发生于毕托管另一侧;通过对毕托管外壁改型优化的方法较传统的增大毕托管管径方法对甩油溢油现象抑制更加有效。结果为探究抽蓄机组水导轴承润滑油系统出现的甩油溢油现象机理与提出有效应对策略提供了理论基础和工程实践参考。

水导轴承润滑油系统甩油溢油现象在抽蓄机组运行中频发,显著影响了机组的安全稳定性和电站的运行环境。借助CFD数值模拟技术和VOF多相流模拟方法,探究了抽蓄机组抽水模式下水导轴承润滑油系统在多油位工况内部流动的动态特性。结果表明,低油位工况下系统流动循环形成更快,过渡过程流态稳定且油位较低,因此甩油现象更轻微,但过低油位可能导致不利于油温的控制;高油位工况下,流动前期甩油溢油现象多发生于旋转油盆毕托管侧附近,流动后期多发生于毕托管另一侧;通过对毕托管外壁改型优化的方法较传统的增大毕托管管径方法对甩油溢油现象抑制更加有效。结果为探究抽蓄机组水导轴承润滑油系统出现的甩油溢油现象机理与提出有效应对策略提供了理论基础和工程实践参考。

The phenomenon of oil spilling and oil spilling in the lubricating oil system of the water guide bearing occurs frequently during the operation of the pumped-storage unit, which significantly affects the safety and stability of the unit and the operating environment of the power station. With the help of CFD numerical simulation technology and VOF multiphase flow simulation method, the dynamic characteristics of water guide bearing lubricating oil system in the multi-oil level working condition under the pumping mode of the pumped-storage unit were explored. The research results show that under the low oil level condition, the system flow cycle is formed faster, the flow state is stable and the oil level is low during the transition process, so the oil rejection phenomenon is milder, but too low oil level may lead to unfavorable control of oil temperature; Under the condition of high oil level, the phenomenon of oil spillage in the early stage of the flow mostly occurs near the side of the Pitot tube of the rotating oil basin, and it mostly occurs on the other side of the Pitot tube in the later stage of the flow. Compared with the traditional method of increasing the diameter of the Pitot tube, the method of optimizing the outer wall of the Pitot tube is more effective in suppressing the phenomenon of oil spillage. The results provide a theoretical basis for exploring the causes of the oil spill phenomenon in the water guide bearing lubricating oil system of the pumped-storage unit and the optimization of the oil slinger.
