我厂于１９９７年由某研究中心设计的６．３ＭＮ液压折板机自试用以来，一直出现低压泵无法工作，两缸同步不稳定，终点行程阀无法投入工作等问题。我们对其液压传动系统充液阀控制油路进行改进后，取得了良好的效果。图１改进后的６３００ｋＮ折板机液压原理图１液压原理...
I plant in 1997 by a research center designed 6.3MN hydraulic folding machine since the trial, there has been low-pressure pump can not work, unstable two-cylinder synchronization, the end of the travel valve can not be put into work and other issues. We have achieved good results by improving the control circuit of the hydraulic drive system charge valve. Figure 1 improved 6300kN flapper hydraulic principle diagram 1 hydraulic principle ...
