摘　　要：工程机械中普遍采用液压传动系统,要求系统集成化程度高,密封性好,能量损失小。鉴于此,基于二通插装阀的液压系统标准控制单元进行设计与研究。建立了三通集成块,并验证了其可行性。采用2个标准控制单元控制液压系统,列举了标准控制单元的12种控制功能。同时,搭建了系统仿真模型,验证了标准控制单元控制液压系统的合理性。仿真结果表明:标准控制单元控制的回路可实现液压缸的快进和负负载流量再生功能,达到节能的目的。Construction machinery generally adopts hydraulic transmission system.It requires high degree of integration,good sealing and small energy loss.In view of this,this paper is based on the design and research of the hydraulic system standard control unit of the two-way cartridge valve.The three-way manifold two valves are established and the feasibility are verified.Two standard control units are used to control the hydraulic system,and twelve control functions of the standard control unit are listed.At the same time,a system simulation model is built to verify the rationality of the standard control unit to control the hydraulic system.The simulation results show that the circuit controlled by the standard control unit can realize the fast forward and negative load flow regeneration functions of the hydraulic cylinder to achieve the purpose of energy saving.
