摘　　要：轴流式油气混输泵兼具泵和压缩机的性能,结构紧凑,能在高含气率下工作。针对混输泵内部流动复杂易产生气液分离,气相能量携带能力差,效率低,稳定性差,设计难度大等问题,采用轴流泵和轴流压缩机设计方法相结合,充分考虑高含气率下气相的可压缩性,用PRO/E对轴流式油气混输泵吸入室及压缩级建模,ICEM对模型划分网格,基于RNG k-ε紊流模型用FLUENT软件对不同含气率下模型流场流动情况进行了计算模拟;分析了流场模拟结果,并进行了实验。结果表明,利用此吸入室、压缩级的设计方法和模拟是合理的。The axial gas-oil multiphase pump has the performance of both pump and compressor. It has a compact stucture, and can work in high volume fraction. But the internal flow in axial gas-oil muhiphase pump is complex, and it has low efficiency and low instability. Design methods of both the axial pump and the axial compressor have been combined, and the compressibility in high volume fraction has been considered. By using PRO/E the axial gas-oil multiphase pump model is built. Based on k-ε turbulent flow model, the internal flow field in different volume fraction is simulated. The analysis of the flow field gave some good advice for the improvement of the pump performance. Experiment showed that this method is feasible in the design of inhalation chamber and the gas-oil pump.
