JL-901型高压油管压力波检测仪在DF_(8B)型机车上的应用

Application of JL-901 high-pressure fuel pipe pressure wave detector to DF_(8B) locomotive diesel engine

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。

In this paper,the detection principle of JL-901 high-pressure fuel pipe pressure wave detector was described.At the same time,the threshold values of pressure wave parameters of DF_(8B)locomotive were determined by the way of experiment.By comparing the corrected threshold values with the typical pressure waves,it could be seen that the detection accuracy of the detector is increased.
