Excavator energy recovery method and device, excavator and storage medium
The invention relates to the technical field of engineering vehicles, in particular to an excavator energy recovery method and device, an excavator and a storage medium. The excavator energy recovery method comprises the following steps that in the excavating process of an excavator, the demand flow of a movable arm is determined according to the intention of a driver, and the intention of the driver is obtained through a pilot handle; when the excavator is in a rotating state, rotating high-pressure oil of at least part of the rotating hydraulic loop is recovered and flows to the movable arm hydraulic cylinder, and the required flow of the movable arm hydraulic cylinder is kept unchanged; the oil flow conveyed to the movable arm hydraulic cylinder by the hydraulic pump is reduced; and the rotating speed of the engine is reduced. The flow of oil entering the oil cylinder of the movable arm can be ensured by reducing the flow of the hydraulic pump, so that the impact of the movable arm is small, the oil consumption of the hydraulic pump is reduced, and the controllability of the whole excavator is good. And the speed of the engine is reduced, so that the overall controllability of the excavator can be improved. According to the excavator energy recovery method, cooperative work of the engine and the hydraulic pump can be achieved.
本发明涉及工程车辆技术领域，尤其涉及一种挖掘机能量回收方法、装置、挖掘机及存储介质。挖掘机能量回收方法包括如下步骤：挖掘机在挖掘过程中，根据驾驶员意图确定动臂需求流量，驾驶员意图由先导手柄获得；挖掘机处于回转状态时，至少部分回转液压回路的回转高压油回收流向动臂液压缸，且动臂液压缸需求流量保持不变；减小液压泵输送给动臂液压缸的油液流量并降低发动机转速。液压泵流量降低能够保证进入动臂的油缸的油液的流量，这样可使动臂冲击小，液压泵的油耗降低，挖掘机整机的操控性好。而发动机速度减小则能够改善挖掘机整体的操控性。本发明提供的挖掘机能量回收方法能够实现发动机与液压泵的协同工作。
