Valve outer confluence hydraulic system and excavator
The invention relates to the technical field of excavator hydraulic control, in particular to a valve outer confluence hydraulic system and an excavator. The valve outer confluence hydraulic system comprises a hydraulic energy supply module, a starting module, a confluence module, a control module, a main valve and a breaking hammer, wherein the hydraulic energy supply module comprises at least two hydraulic pumps, and each hydraulic pump can supply oil to the main valve; the confluence module is communicated with the main valve in parallel, the confluence module is connected between the starting module and the breaking hammer, and all the hydraulic pumps are communicated with the confluence module; the starting module is connected with the confluence module through the control module; andafter the starting module is started, the control module controls the confluence module so that the n hydraulic pumps can supply oil to the breaking hammer through the confluence module, n is a natural number, and n is larger than or equal to zero and smaller than or equal to the number of the hydraulic pumps. When the valve outer confluence hydraulic system provided by the invention is used forsupplying oil to the breaking hammer, the oil supply requirements of breaking hammers with drill rods of different sizes can be met, the pressure loss is small, and the energy utilization rate is high.
一种阀外合流液压系统及挖掘机，涉及挖掘机液压控制技术领域，所述阀外合流液压系统包括液压供能模块、启动模块、合流模块、控制模块、主阀和破碎锤，其中，液压供能模块包括至少两个液压泵，各液压泵均能够为主阀供油；合流模块与主阀以并联方式连通，且合流模块连接于启动模块与破碎锤之间，各液压泵均与合流模块连通；启动模块通过控制模块与合流模块连接，启动模块启动后，控制模块控制合流模块，以使得n个液压泵通过合流模块为所述破碎锤供油，n为自然数，n大于等于零且小于等于所述液压泵的数量。使用本申请提供的阀外合流液压系统为破碎锤供油，可满足不同尺寸钎杆的破碎锤的供油需求，且压力损失小，能量利用率高。
