摘　　要：JDX-1500型顶驱式全液压岩芯钻机液压系统主要由给进回路、回转回路、升降回路、起塔回路、夹持回路和调平回路等组成。利用恒压式变量泵系统与负载敏感技术使给进机构和回转机构液压系统更符合钻探工艺的要求,并且具有显著的节能效果。钻机可操作性好,液压系统安全性高,有良好的启动特性。试验表明液压系统设计合理、运行可靠。Hydraulic system of model JDX-1500 top-driven, fully hydraulic rock mandril drill consists of thrust circuit, rotation circuit, lifting circuit, towing hoisting circuit, clamping circuit and leveling circuit. Application of variable displacement pump system with constant pressure and load-sensing technology make the hydraulic systems of thrust mechanism and the rotation mechanism meet the requirements of drilling processes better and significant energy-saving effect is obtained at the same time. The drill features better operation performance, safer hydraulic system and satisfactory starting character. Test shows that the hydraulic systems demonstrate rational design and reliable operation.
