The design of the hydraulic system is the basis of known conditions to determine the work program of hydraulic, hydraulic flow, pressure and hydraulic pumps and other components of the design. To sum up, the need to complete the entire design process to conduct a series of hard work. Enter here Abstract In this paper, focused on the combination of dual-use horizontal boring drilling machine hydraulic system, to achieve the duty cycle is: work fast forward feed situ rapid return to stop, hydraulic technology is mechanical equipment in the fastest growing technologies.
