摘要: 增压引射器利用蒸汽作为动力使水增压,让出口水的压力超过入口蒸汽的压力。增压的特点使增压引射器可用于核电的非能动安全系统,但有关的设计研究较少。本文对基于两相流激波的增压引射器进行研究,给出其设计方法,并进行了试验研究,得到了增压效果。试验所得的特性曲线与设计的特性曲线相比较,结果吻合较好,充分说明了设计方法的正确性和可靠性。

Abstract: In the steam injector with pressure-gain, the water gains pressure by the power of steam. The outlet water pressure is higher than the inlet steam pressure. The characteristics of pressure-gain makes it possible to use the injector in the nuclear passive safety system. The study on the injector design is rarely reported. This paper presents the method to design the steam injector with pressure-gain. An experimental system was established according to the design. The experimental characteristic curve agrees well with the design curve, which proves the security and reliability of the design.
