介绍了JL-901型高压油管压力波检测仪的检测原理,并通过试验确定出DF8B型机车压力波参数的门限值范围,采用修正后的门限值与典型波对比的分析判断方法,提高了检测的准确率。
The detection principle of JL-901 high-pressure tubing pressure wave detector is introduced and the threshold range of pressure wave parameters of DF8B locomotive is determined through experiments. The corrected threshold value is compared with the analysis and judgment of typical wave to improve The accuracy of detection.
