RH精炼拉瓦尔喷嘴设计与寿命评估

RH Refining Laval Nozzle Design and Life Evaluation

主要讲述了拉瓦尔喷嘴的设计原理,结合对喷嘴的实际测量数据,完成对RH蒸汽喷射泵各级拉瓦尔喷嘴的国产化设计,通过对使用后的喷嘴喉口尺寸进行测量分析实现对喷嘴寿命的评估,从而降低设备故障。

This article mainly tells the story of the design principle of laval nozzle,combined with the actual measurement data of nozzle,complete localization of laval nozzle at all levels of RH steam jet pump design,through the use of the nozzle throat size measurement analysis for the nozzle life assessment,reducing equipment failure.
