运用层次分析方法为影响水气射流风机吸风量的三个重要影响因素(水压、喉嘴距、管径比)建立层次分析模型,并根据决策判定量化原则,得出判断矩阵,最后计算出各个影响因素指标的权重。结果表明,水压对吸风量的影响最大,其次是喉嘴距,最后是管径比。该研究结果可以为水气射流风机设计过程中的优化决策提供理论性指导。 Analytic Hierarchy Process (AHP) is used to establish the AHP model for the three important influencing factors (water pressure, throat distance and pipe diameter ratio) that affect the amount of air suction of air-jet fan. The judgment matrix is ​​obtained according to the principle of decision- The weight of each influencing factor index. The results show that water pressure has the greatest effect on the amount of suction, followed by the throat distance, and finally the pipe diameter ratio. The results of this study can provide theoretical guidance for the optimization decision-making in the design process of the water vapor jet fan.
