高速开关阀控制的无级调节工作参数液压凿岩机

Hydraulic drill with stepless regulating work parameters based on hi-speed on off valve control

液压凿岩机输出的工作参数与不同工况相匹配从而获得最佳的工作效率一直是人们关注的焦点，本文利用计算机技术开发了一种基于高速开关阀控制的无级调节工作参数的液压凿岩机。

The focus, that the optimum work efficiency can be obtained by the hydraulic drill output work parameters matched with operation under different condition, is concerned all the times. Utilizing the computer technique, the authors develops a hydraulic drill with stepless regulating work parameters controlled by hi-speed on-off valve.
