【摘要】：针对半无头轧制卷取机下夹送辊液压阀台不能快速泄压的问题进行了阀台的调定。在调定中,根据先导减压阀与先导溢流阀的压力变化情况,最终确定了问题的原因在于先导溢流阀中先导油的供排方式不合理。找出了同一套远程调压系统共同控制先导减压阀的减压与先导溢流阀溢流的优缺点。通过深入分析液压阀的结构与调压原理,可更好地根据调试时液压回路中各点的压力变化分析解决液压系统中存在问题。
[Abstract]:Aiming at the problem that the hydraulic valve table of the clamping roller under the semi-headless rolling coiler can not release the pressure quickly, the adjustment of the valve table is carried out.According to the pressure variation of the pilot relief valve and the pilot relief valve, the reason of the problem is the unreasonable supply and discharge mode of the pilot oil in the pilot relief valve.The advantages and disadvantages of the pressure-relief and pilot relief valve relief controlled by the same remote pressure regulating system are found out.By deeply analyzing the structure of hydraulic valve and the principle of pressure regulation, the existing problems in hydraulic system can be better solved according to the pressure variation of every point in hydraulic circuit during debugging.
