Power system energy-saving control method and device and excavator
The invention discloses a power system energy-saving control method and device and an excavator, and belongs to the technical field of excavator energy-saving control. The technical problem that in the prior art, when an excavator engine is started with loads, starting is unstable is solved. The device comprises an energy-saving coupler used for being in transmission connection with the output end of an engine and the input end of a main pump, wherein when the energy-saving coupler is combined, power transmission is achieved between the engine and the main pump, and when the energy-saving coupler is disengaged, power transmission between the engine and the main pump is interrupted; a hydraulic control system used for realizing combination or separation of the energy-saving coupler according to a control instruction of a controller; and the controller electrically connected with the engine and used for collecting operation parameters of the engine and sending a control instruction to the hydraulic control system based on the operation parameters of the engine and the selected control mode.
本发明公开了挖掘机节能控制技术领域的一种动力系统节能控制方法、装置以及挖掘机，以解决现有技术中挖掘机发动机带负载启动时，启动不平稳的技术问题。包括：节能联轴器，用于与发动机的输出端和主泵的输入端分别传动连接，当节能联轴器结合时，发动机与主泵之间实现动力传输；当节能联轴器脱开时，发动机与主泵之间的动力传输中断；液压控制系统，用于根据控制器的控制指令，实现节能联轴器的结合或脱开；控制器，与发动机电连接，用于采集发动机的运行参数，并基于发动机的运行参数和选定的控制模式，向液压控制系统发送控制指令。
