Hydraulic energy supply system and excavator
The invention discloses a hydraulic energy supply system and an excavator, and relates to the technical field of excavators. The hydraulic energy supply system comprises a first pumping device, a second pumping device, a main valve, a converging valve, a first flow regulating valve, a second flow regulating valve, a switching device and a breaking hammer; the first flow regulating valve is used for regulating the displacement of the first pumping device, and the second flow regulating valve is used for regulating the displacement of the second pumping device; the switching device is used for switching the hydraulic energy supply system from an excavation mode to a crushing mode; in the excavation mode, the first pumping device and the second pumping device are used for supplying oil to themain valve; and in the crushing mode, the first pumping device supplies the oil to the breaking hammer through the main valve, and the second pumping device supplies the oil to the main valve and supplies the oil to the breaking hammer through the converging valve. When double pumps are adopted by the hydraulic energy supply system to supply the oil, the oil conveyed by the second pumping devicecan reach the breaking hammer without passing through the main valve, the oil pressure loss is smaller, the heat productivity is relatively smaller, and the energy loss is smaller.
一种液压供能系统及挖掘机，涉及挖掘机技术领域，所述液压供能系统包括第一泵送装置、第二泵送装置、主阀、合流阀、第一流量调节阀、第二流量调节阀、切换装置和破碎锤；第一流量调节阀用于调整第一泵送装置的排量，第二流量调节阀用于调整第二泵送装置的排量；切换装置用于将液压供能系统由挖掘模式切换为破碎模式；在挖掘模式，第一泵送装置和第二泵送装置分别用于向主阀供油；在破碎模式，第一泵送装置通过主阀为破碎锤供油，第二泵送装置向主阀供油，且通过合流阀为破碎锤供油。所述液压供能系统在采用双泵供油时，第二泵送装置输送的油液无需经过主阀即可到达破碎锤，油液压力损失更小，发热量相对更小，能量损失更小。
