| Abstract: | In oilfields,two-screw pump is a supercharging equipment used for oil-gas mixing delivery,and the back flow in it is an important factor influencing its performances.The geometrical characteristics of its cavity and back-flow pathway were analysed,and the back-flow models of different shape pathways were established.Back-flow volume is related to pressure difference and gas content. It decreases with the increase of gas content, and with the decline of pressure difference. |
