一、前言在蒸汽喷射器方面,首要的问题是混合室的真空度和被压缩气体吸入量的关系,也就是性能曲线。在前两篇研究报告中对此没有提及。要想知道这一点,必须阐明蒸汽喷射器的扩压器内混合气体状态的变化,而在蒸汽喷射器的设计时必须首先求出性能曲 I. INTRODUCTION In the area of ​​steam injectors, the primary problem is the relationship between the degree of vacuum in the mixing chamber and the amount of gas being drawn in, that is, the performance curve. This is not mentioned in the previous two studies. To know this, you must clarify the steam injector diffuser mixed gas state changes, and in the design of the steam injector must first find performance song
