2.6 计算、选择液压元件及辅件当在草图中已初步选择了能源及其它回路后,便应根据草图方案进行具体的计算,以便选择元件和验证所选方案是否合适。2.6.1 双泵供油系统的油泵工作压力、流量、传动功率的计算和确定:双泵供油系统的工作特点是,执行部件快进、快退时由双泵供油,执行部件工作进给时由高压泵单独供油,辅助系统的快速移
2.6 CALCULATION AND SELECTION OF HYDRAULIC ELEMENTS AND ACCESSORIES Once the energy and other circuits have been initially selected in the sketches, specific calculations should be made according to the sketching scheme in order to select the elements and verify that the chosen scheme is appropriate. 2.6.1 Calculation and determination of working pressure, flow rate and transmission power of double pump oil supply system: The working characteristic of double pump oil supply system is that the executive part is fed by double pump in fast forward and rewind, When given by the high-pressure pump alone oil, auxiliary system quickly move
