The invention relates to an ultra high pressure and large flow telescopic oil pipe follow-up oil transportation method. Including the expansion oil pipe, the upper end valve block, the lower end valve block, and then the oil pipe with the oil pipe, the upper end valve is connected to the tubing cylinder, the oil filling valve is filled with oil, the high pressure flange is connected to the high pressure oil, and the oil pipe cylinder is fed through the valve block to improve the oil pressure. The tubing cylinder connection support block is fixed on the hydraulic machine frame. The oil pipe piston is fixed on the lower end valve block through the piston ring, the lower end valve block and the movable beam of the hydraulic press are moved, the high-pressure oil liquid is injected from the upper end valve block, and the oil pipe is transported to the lower end valve through the hollow piston tubing in the tubing cylinder to realize oil transfer from the oil pipe fixed on the frame to the movable horizontal beam. The invention breaks through the restriction of pressure resistance of high pressure hose fluid, large oil transport flow, small space, meet the needs of high pressure hydraulic press, and improve the working efficiency of hydraulic press, versatility, wide application and high safety.
