摘　　要：针对外啮合齿轮泵在工程应用过程中噪声过大的缺点,采用流体动力学分析软件FLUENT动网格技术,对某型号外啮合齿轮泵的内部流场进行了模拟分析,得到不同负载压力及转速下的齿轮泵的困油、泄漏及流量脉动情况,并在此基础上对齿轮泵的噪声进行分析,最终提出了齿轮泵合理的工作转速范围。For external gear pumps＇ shortcoming of too much noise in the engineering application process,using dynamic method technology of fluid dynamics analysis software FLUENT,internal flow field of a type of external gear pump was simulated and analyzed,the trapped oil、leak and flow pulsation of gear pump under different pressure and speed were got,the noise of gear pump was analyzed on this base and finally put forward a reasonable speed range of gear pump.

关 键 词：外啮合齿轮泵 FLUENT 内部流场 噪声
