CY6型铲运机及其恒压式液压系统

Model CY6 IHD Machine and Its Constant Presure Hydraulic System

ＣＹ６型铲运机的研制是国家科委下达的“九五”攻关项目，其斗容为６ｍ３。本文阐述了它的参数、结构特点，并着重对其变量泵供油的恒压式液压系统的结构和原理进行了详细论述。

he development of model CY6 LHD machine with 6m3 bucket volume is one of the key programs of the 9th FiveYear plan assigned by Chinese Science and Technology Commision.This paper descriped its major technical parameters and structural properties,and emphatically discussed the structure and principle of constant pressure hydraulic system for the oil supply of variable displacement pump in detail.
