# 集液管及其内部导流板对旋喷泵性能的影响Influence of the Collector and the Inner Guide Vane on Roto-Jet Pump Performance

Abstract: Numerical simulation was conducted to investigate the influence of the collector on the perfor-mance of a roto-jet pump. Distributions of velocity, static pressure as well as turbulent kinetic energy were obtained thereby. A comparison was implemented on flow parameter distributions at different flow rates. The emphasis was placed upon the effects of the collector and the inner guide vane on flows and the hydraulic forces exerted on the collector. Remarkable flow regularity is ob-served in the rotating chamber. High static pressure gradients occur at the inlet and the turning positions of the collector. Without the guide vane, overall turbulent kinetic energy is high but the pump performance is favorable relative to its counterparts with the guide vane. The resultant hy-draulic force acting upon the collector decreases with the increase of flow rate. The force component along the pump axis is predominant in this connection. A slight reduction of hydraulic force is manifested with the introduction of the guide vane.
