这篇报告将介绍电液先导阀对大功率主阀的控制。这种方案是可以实现的,因为它已在实验室内经过试验,并且在野外大型液压挖掘机上经过考核。实验结果表明,电动手控装置和电液控制压力调节阀的结合,能够给电液先导控制系统带来巨大的功率。对主阀实行高灵敏度控制的这一系统,可作为将来调节回路的部件,甚至可以作为计算机操作的一个部件。在大型的地下作业机械和建筑机械上,必须装备这种现代化的电液控制。这个必要性就成为这种实验型的电液先导控制系统(电液先导控制EHPC)继续发展、并将日趋成熟的推动力量。下面,就这种方法作一说明。
This report will introduce the electro-hydraulic pilot valve on the control of high-power main valve. This solution is achievable because it has been tested in the laboratory and has been evaluated on a large hydraulic excavator in the field. The experimental results show that the combination of the electric hand-operated device and the electro-hydraulic control pressure regulating valve can bring huge power to the electro-hydraulic pilot control system. This system of highly sensitive control of the main valve can be used as part of the future regulating circuit and even as a part of computer operation. In the large-scale underground machinery and construction machinery, must be equipped with this modern electro-hydraulic control. This necessity became the driving force for the development of this experimental electro-hydraulic pilot control system (electro-hydraulic pilot control EHPC) and its maturation. Below, on this method to make a statement.
