Abstract:The application and development of the oil-gas multiphase pump are introduced.To keep the homogenization of liquid and gas,and to prevent medium from separating in flowing part,the key for multiphase pump transporting mixture of gas and liquid is to optimize the flow part of the multiphase pump,especially impeller and lamina.By combining the theory of axial pump and axial compressor,the whirly impeller is designed with consideration of static and dynamic lamina in axial pump and axial compressor.The 2D impeller is transformed into 3D space by coordinate-change,and three-dimensional entitative model was built by Pro/E.The result shows that the shape of lamina can be expressed exactly by 3D modeling which is built by Pro/E,and an ideal 3D entitative model can be created at the same time
