摘　　要：为了满足深部固体矿产、油页岩、煤层气、天然气水合物等资源勘探开发的需要,提出了钻机负荷传感泵控液压系统的设计思路。通过建立模型,重点分析了给进调压系统、回转和升降调速系统的工作原理、节能效率和静动态特性等。其分析和室内试验结果表明,与以往钻机相比,系统调压稳定,具有良好的无级调速和带载平稳启停功能,在运行过程中能量损耗较小,具有显著的节能效果。To satisfy the requirements of exploiting deep-seated solid minerals, oil shale, coal seam gas, gas hydrate, etc, promote the load sensing pump control system applied to the core-drilling rig. By modeling, mainly＂ analyze the operating principle, the energy-saving efficiency and the dynamical properties of the feeding pressure-regulating system and rotation and hoisting speed-regulating systems. lts analysis and indoor experiment show that this rig characterizes the stable pressure regulation, the better stepless speed regulation and steady start-stop function with load, and there is less energy consumption, with the remarkable energy-saving effects.
