The secondary oil return pipeline 14 is connected to the secondary hydraulic pump station 2. The multi-purpose distribution body 9 is connected to multiple high-pressure oil outlets 15, and each high-pressure oil outlet 15 is provided with a pump pressure distribution body 16. The pump pressure distribution body 16 is used to distribute the high-pressure liquid provided by the secondary booster device 6 to the multiple high-pressure oil outlets 15; the primary oil inlet pipeline 3, the primary oil return pipeline 5, the secondary The oil inlet pipeline 7 and the secondary oil return pipeline 14 are both composed of rigid oil pipes 17 at two ends and a section of flexible high-pressure oil pipe 18. The two ends of the flexible high-pressure oil pipe 18 are respectively connected to the two sections of rigid oil pipes 17. The flexible high-pressure oil pipe 18 is used for the bending arrangement of the pipeline. The primary hydraulic pump station 1 increases the pressure in the primary booster device 4 through the primary oil inlet pipeline 3, and the primary booster device 4 supplies pressure to the secondary booster device 6.
