齿轮油泵结构简单,体积小,自吸能力强,常用于油田、港口、码头和船舶等大流量输油、卸油中。本文建立了齿轮油泵的物理模型,并采用Fluent软件,采用动网格技术对齿轮油泵进行了动态数值模拟。重点分析了齿轮油泵在齿轮旋转情况下的内部压力场和速度场的变化,为今后齿轮油泵的设计和结构优化提供很多有价值的参考数据。

Gear pump is one equipment,which has simple structure,small volume,and strong self-priming capacity.It is often used to transport oil in oil field,ports,docks and vessels.The gear pump physical model is established,and the moving grid technology of Fluent is used to dynamic simulate the flow in gear pump.The paper analyzed the internal pressure and velocity field when the pump was rotating.So the paper provided a lot of valuable reference data for the design and structure optimization of gear pump.
