Hydraulic control method and device for breaking hammer and operation machine
The invention relates to the technical field of striking and crushing, and provides a hydraulic control method and device for a breaking hammer and an operation machine.The hydraulic control method for the breaking hammer comprises the steps that a hydraulic flow demand value during operation of the breaking hammer is obtained; the front pump and the rear pump are set to have a first working state and a second working state, the first working state is the minimum displacement, and the second working state is the normal output flow; the sum of the minimum displacement and the normal output flow is equal to a hydraulic flow demand value; one of the front pump and the rear pump is set to be in a first working state, and the other is set to be in a second working state; setting the switching time of the working states of the front pump and the rear pump; and switching the working states of the front pump and the rear pump according to the switching time. According to the breaking hammer hydraulic control method and device and the operation machine, the front pump and the rear pump are abraded to the same degree, the problem that the front pump or the rear pump is excessively abraded independently is solved, and meanwhile the working efficiency of the front pump and the working efficiency of the rear pump are improved.
本发明涉及打击破碎技术领域，提供一种破碎锤液压控制方法、装置及作业机械，其中，破碎锤控制方法包括步骤：获取破碎锤作业时的液压流量需求值；设定前泵和后泵均包括第一工作状态和第二工作状态，第一工作状态为最小排量，第二工作状态为正常输出流量；最小排量与正常输出流量的总和与液压流量需求值相等；设定前泵和后泵中其中一者为第一工作状态，另一者为第二工作状态；设定前泵和后泵工作状态的切换时间；根据切换时间切换前泵和后泵的工作状态。本发明提供的破碎锤液压控制方法、装置及作业机械，使得前泵和后泵产生相同程度地磨损，解决了前泵或后泵单独过度磨损，同时还提高了前泵和后泵的工作效率。
