柱塞油泵的流场数值研究

摘要

According to the plunger pump structure, combined with the plunger and the valve ball model, with the dynamic gridding technology and the profile of programming module from the secondary development of Fluent,the result of the plunger and the valve ball movement coupled with the flow field are got. The flow field of the plunger chamber in time, the evolution during the flow field, the movement of ball and the features of flow field with the movement of the plunger piston can be calculated to determine. Pump provides a reference and a basis for the study.%据柱塞油泵结构,结合柱塞和阀球运动模型,运用动网格技术和自编程profile模块对Fluent进行二次开发,实现了柱塞和阀球运动与流场的耦合求解.可以确定柱塞腔内部任意计算时刻流场状态,柱塞运动过程中柱塞内部流场演化、阀球运动和流场特性,为研究油泵提供了参考和依据.
