摘要
掘进机锚杆钻机液压系统为星轮马达与锚杆钻机共泵系统。其泵控系统采用恒压、负载敏感控制,控制阀采用负载敏感比例多路换向阀,在系统中加高压三通球阀,实现星轮马达与锚杆钻机间的切换,并实现安全互锁。
Planet motor an hydraulic jumboher use the common bump in road - header, the hump system is equipped with the function constant voltage and sensitive to load, the valve system adopt load - sensitiveity type, a muhipath globe - valve is adopted in the system. It can switch the way in planetmotor with jumbolter and avoid interference.
