摘　　要：为提升凿岩自适应控制性能,以全液压的方式实现凿岩回转推进自适应控制。通过推进联、溢流阀、负载敏感变量泵等的特殊匹配,实现推进压力液压远控;通过推进压力液压远控、平衡阀耦合两溢流阀设定值、回转压力控制平衡阀开度等技术措施,实现回转推进全液压自适应耦合控制。理论分析、仿真分析及试验测试表明,该全液压自适应控制系统性能良好,可靠性高,有效提升钻进过程的岩层适应性。For improving the auto adjusting performance of rock alized by a total hydraulic mode. Through special matching of a drilling, the rotation and feed auto adjusting is re- feed valve section, a relief valve and a load sensi- tive variable pump, the feed pressure hydraulic remote control is realized. Through feed pressure hydraulic remote control, the balance valve coupling of two relief valve, rotation pressure control balance valve orifice opening, rota- tion and feed total hydraulic auto adjusting are realized. Theoretical analysis, simulation analysis test show that the total hydraulic auto adjusting system has good performance and high reliability rock adaptation in drilling process. and experimental , which improves
