本文主要是针对AHV-Ⅳ362、AHV-Ⅳ364型可控震源驱动马达-驱动泵壳体散热液压回路污染及驱动泵、驱动马达、散热器一同损坏的原因分析,并提出改进散热回路,确保油路清洁,从而减少故障率,延长液压元件的使用寿命。

利用AutoCAD2000的高级制定功能,进行二次开发,建立了一套用于绘制液压系统原理图的图形符号库,并介绍了液压元件符号库的建立过程,从而简化了液压原理图的绘图过程,提高了绘图效率。

本文针对CAT320DL挖掘机液压系统经常出现的故障进行列举和分析,并提出了解决方案,并指出液压系统故障需要遵循的一些原则和注意事项,为预防和维修提供参考依据。

In order to supply theoretical guidance to hydraulic transformer's design and application,the effect of the number of plungers in hydraulic transformer on its flow characteristic is analyzed,theoretical analysis and simulation are done on hydraulic transformer's flow characteristic when the number of plungers is different.Based on the working principle of swash plate piston hydraulic components,mathematical models of instantaneous flow and flow pulsation rate are built,and simulation study is done with MATLAB.As a result,the effect is found,and some conclusions worth referring to are obtained.
