摘　　要：以Q10型潜油电泵为研究对象,利用CFD技术进行变流量工况下内流场数值仿真研究。结果表明:小流量和大流量工况下,叶轮流道内存在漩涡;非设计流量工况下,叶轮流道内的损失较大;设计工况下,泵的效率最高。为潜油电泵的改型优化设计提供理论指导。The Q10 submersible pump was selected as the research prototype pump,which flow field value was simulation researched with its inter-flow characteristic under off-condition by CFD technology.The research results show that under small flow and large flow conditions,there is a vortex in the impeller flow channel,under the non-design flow condition,the loss in the impeller flow channel is large and under the design condition,the pump has the highest efficiency.The theoretical direction for the optimization design of electrical submersible pump has been provided.
