Hydraulic control system, excavator and excavator control method
The invention provides a hydraulic control system, an excavator and an excavator control method, and relates to the technical field of excavators. The hydraulic control circuit of the excavator is optimized to a certain extent to improve the stability of the hydraulic control system. The hydraulic control system comprises an engine, a transfer case, variable pumps, a control valve, a walking powerdevice, a rotary power device and a plurality of oil cylinders. A plurality of variable pumps are connected with the engine through the transfer case correspondingly. One of the plurality of variablepumps is connected with the walking power device, one variable pump is connected with the rotary power device, the other variable pumps are connected with the plurality of oil cylinders each to each,and the control valve is connected with the plurality of variable pumps to control the work of each variable pump.
本发明提供的一种液压控制系统、挖掘机及挖掘机控制方法，涉及挖掘机技术领域，以在一定程度上优化挖掘机的液压控制回路，提高液压控制系统的稳定性。本发明提供的液压控制系统，包括发动机、分动箱、变量泵、控制阀、行走动力装置、回转动力装置以及多个油缸；变量泵为多个，且多个变量泵通过分动箱分别与发动机相连接；多个变量泵中的一个变量泵与行走动力装置相连接，一个变量泵与回转动力装置相连接，其余变量泵一一对应地与多个油缸相连接，且控制阀与多个变量泵相连接，用于控制各个变量泵的工作。
