Oil supply hydraulic system and excavator hydraulic system
The invention relates to an oil supply hydraulic system which comprises a first oil inlet P1, a second oil inlet P2, an oil return port T, a first control unit, a second control unit and a pressure comparison unit. The second executing mechanism is connected to a second oil inlet path and a second oil return path through a second control unit, the second oil inlet path is provided with a flow control unit used for controlling the flow of the second oil inlet path, and two comparison oil ports of the pressure comparison unit are connected with load oil ports of the first control unit and the second control unit respectively. And an oil outlet C of the pressure comparison unit is connected with the flow control unit so as to feed back higher load pressure in the first control unit and the second control unit to a control oil port of the flow control unit. In addition, the invention further relates to an excavator hydraulic system. According to the oil supply hydraulic system, it can be guaranteed that the composite action has good coordination, and the working efficiency is improved.
本发明涉及一种供油液压系统，该系统包括第一进油口P1、第二进油口P2、回油口T、第一控制单元、第二控制单元和压力比较单元，第一控制单元通过第一执行机构连接于第一进油油路和第一回油油路，第二执行机构通过第二控制单元连接于第二进油油路和第二回油油路，第二进油油路设置有用于控制第二进油油路流量的流量控制单元，压力比较单元的两个比较油口分别与第一控制单元和第二控制单元的负载油口连接，压力比较单元的出油口C连接流量控制单元，以将第一控制单元和第二控制单元之中较高的负载压力反馈到流量控制单元的控制油口。此外，本发明还涉及一种挖掘机液压系统。本发明供油液压系统能够保证复合动作具有较好的协调性，提高工作效率。
