Energy-saving hydraulic transmission system of excavator
The invention relates to the field of engineering machinery, in particular to an energy-saving hydraulic transmission system of an excavator. The energy-saving hydraulic transmission system comprisesan oil tank, an engine, a main pump, a pilot pump, a pilot control handle, a main valve, and an air conditioner controlled by the engine, and further comprises a controller. The engine is provided with an engine electromagnetic valve for controlling the starting and stopping states of the engine, and the pilot control handle is arranged to be an electric control handle; the input end of the controller is in signal connection with a displacement sensor of the pilot control handle and is used for monitoring the displacement state of the pilot control handle; and the output end of the controlleris in signal connection with the engine electromagnetic valve and outputs a starting or stopping signal to the engine electromagnetic valve when the pilot control handle is started or stopped. The problem of energy waste caused by keeping the air conditioner running when the excavator is in a standby state is solved.
本发明涉及工程机械领域的一种挖掘机节能液压传动系统,包括油箱、发动机、主泵、先导泵、先导控制手柄、主阀以及受发动机控制的空调,还包括控制器;发动机配置有控制其启停状态的发动机电磁阀,先导控制手柄设置为电控式控制手柄;控制器的输入端与先导控制手柄自带的位移传感器信号连接并用于监测先导控制手柄的位移状态;控制器的输出端与发动机电磁阀信号连接且在先导控制手柄开启或停止时向发动机电磁阀输出启动或停止信号。以解决挖掘机待机时保持空调运转所产生的能量浪费问题。
