摘要
本文利用频率响应试验装置,对Ⅱ号泵和 A 型泵调速器进行了频率响应试验,并根据试验结果对其动态性能进行了理论分析。认为Ⅱ号泵调速器在全油门情况下有足够的稳定性储备,但在怠速情况下稳定性储备很小,不同振幅对其频率特性有一定影响。文中还分析了相位对供油超调的影响。
A study on frequency response of the governor of type A and No.2 injection pumps byusing an experimental frequency respondence apparatus and a theoretical analysis of dynamicperformance was made according to the result of the above experiment.The conclusion wasthat there was enough stability backup for the governor of No.2 injection pump in full loadcondition but less at idle speed,and there was certain influence of amplitude on frequencycharacteristics.In addition,the paper anlaysed the effect of phases on over regulation of fueldilivery.
