摘　　要：现阶段PG9171E燃气轮机用辅助润滑油泵存在成本高、故障率高等缺点,因此亟需自主设计、本土化生产的辅助润滑油泵取代,以降低燃气轮机的工作成本。本文介绍了上海电力公司闸北发电厂燃气轮机专用LYT230-90型辅助润滑油泵的设计方案,该泵可将流量增加15%,电机输出轴与辅助润滑油泵齿轮的同心度降低到0.05mm,大幅提升了其运行平稳性。An auxiliary lubrication pump designed and fabricated locally is needed due to its current shortcomings of high cost and high failure rate, which can largely induce the operation cost. In this work, a specialized auxiliary lubrication pump (LYT230-90) used for the gas turbine of Shanghai Zhabei Power Plant has been designed and its quantity of flow has been enhance by 15 percent and the concentricity has been decreased to 0.05mm, which results in a high operating stability.
