掘进机液压系统与机载锚杆钻机液压系统组成共泵系统,液压泵采用恒功率、恒压、负载敏感,控制阀采用负载敏感液压比例多路换向阀,系统的切换用先导式二位六通换向阀完成,实现2套系统的互锁。
The hydraulic system of boring machine and the hydraulic system of airborne bolting rig consist of a common pump system. The hydraulic pump adopts constant power, constant pressure and load sensitivity. The control valve adopts the load-sensitive hydraulic proportional multi-way directional control valve. Six-way valve to complete, to achieve two sets of system interlocking.
