摘要
主油泵是汽轮机组供油系统中的重要设备,其性能对汽轮发电机组的安全运行有决定性影响。文章针对某12MW等级的主油泵进行三维数值模拟,研究主油泵叶轮内流场分布情况和性能曲线,为汽轮机润滑油系统的设计和故障诊断提供了理论依据。
Main oil pump is the important equipment in turbine oil supply system. The performance of the main oil pump has a decisive effect on the safe operation of the turbo-generator unit. This paper numerically simulates some 12MW turbine main oil pump＇s impeller, studies the fluid distribution and performance characteristic curve and provids some theoretical basis for turbine oil system＇s design and fault diagnosis.
