摘要(Abstract)：

针对普通砂泵在面临黏度较大的废弃钻井液复杂介质时使用效果和能效特性不能满足要求的问题，以一种复合叶片的废弃钻井液混输泵为研究对象，基于原模型结构特性和叶道内流机理，进行叶片结构改进设计，通过多工况试验验证和内部流场数值分析，获得了新型复合叶片叶轮结构对废弃钻井液混输泵水力特性及内流机理的影响规律，结果表明，不同流量工况下仿真和试验的能效特性误差均在5%范围内，仿真结果准确度满足设计要求；改进后模型的水力特性比原模型平均提高了约5.8%，并通过流场特性对比分析得到验证；新型复合叶片叶轮结构驱动力更充分，流场改善更明显；低压区位于叶轮中心，并向叶轮出口处逐渐增加，两有叶区和无叶区流体存在明显的能量和质量转换。研究结果可为废弃钻井液混输泵叶轮复合叶片结构设计和高能效开发提供参考。
In view of the problem that the use effect and energy efficiency characteristics of ordinary sand pump can not meet the requirements when faced with the complex medium of waste drilling fluid with high viscosity,in this study,a mixture pump with composite blades for waste drilling fluid mixture was used as the research object. Based on the structural characteristics of the original model and the internal flow mechanism of the blade passage,the improved blade structure design was carried out.Through experimental verification of multi-working conditions and numerical analysis of internal flow field,the influence law of the impeller structure with new composite blades on the hydraulic characteristics and internal flow mechanism of the waste drilling fluid mixture pump was obtained. The results show that the errors of energy efficiency characteristics of simulation and experiment under different flow conditions are within 5%,and the accuracy of simulation results meets the design requirements.Compared with the original model,the hydraulic characteristics of the improved model are improved by 5.8% on average,and are verified by comparative analysis of flow field characteristics. The impeller structure with new composite blades has more sufficient driving force and the flow field is improved more obviously. The low pressure area is located in the center of the impeller,and gradually increases towards the exit of the impeller. There are obvious energy and mass conversion in the two fluid areas with and without blades. The research results can provide reference for structural design and energy-efficient development of impeller composite blades of waste drilling fluid mixture pump.
