摘要
分析了单车试验器缩堵固定孔径误差、环境温度变化对机能试验的影响程度,以及缩堵孔径+开关型电磁阀模式的单车试验器使用过程中存在的问题,介绍了占空比信号控制高频开关电磁阀模式的单车试验器的优点。
The degree of effect of the fixed reducing and plugging aperture errors of the single-car tester and the environment temperature change on the functional test,as well as troubles in operation of the single-car tester with the reducing and plugging aperture + switch type electromagnetic valve mode is analyzed.The advantages of the single-car tester with the mode of high-frequency switch type electromagnetic valve controlled by duty ratio signal are described.
