自然循环系统中喷射泵特性的实验研究

An Experimental Investigation of Jet Pump's Behaviours in Natural Circulation Loop

在自然循环系统中安装喷射泵并进行了实验研究．研究结果表明，强迫循环时，喷射系工作特性受回路影响较大，同时，调节冷、热段密度差可改变喷射泵在回路中的工作范围．为避免引射支路出现倒流现象，在实验及分析基础上提出了自然循环系统中设计安装喷射系的一些建议．

An experimental study of jet pump installed in natural circulation system has been performed. The results show that the jet pump's working behaviours is greatly affected by the loop's characteristics in forced circulation, and the working range of jet pump can be adjusted by changint'ltiie difference of density between the cold leg and the hot leg. Based upon the experimental results and analysis, some sugestions on hi pump design in natural circulation system are proposed to elimihate the counter flow in suction branch.
