For example, referring to fig. 3, the main valve set 210 is connected to the power plant 100 through an oil pipe, specifically, the main valve set 210 is communicated with the main oil pump, directly receives power from the main oil pump, and transmits the power to the S-pipe valve pump 230, and the main oil pump has a large flow rate to supply power for the S-pipe valve pump 230 to transport materials. The distribution valve bank is connected with a shunt oil pump, the flow rate of the shunt oil pump is relatively small, and the distribution valve bank is only used for supplying the shunt valve bank 140 to control the reversing of the S-pipe valve pump 230.
In the embodiment, the power unit 110 adopts a combination of 355 oil pumps and 260 oil pumps, the flow rate reaches 2400L/min, and the area ratio of the main oil cylinder to the conveying cylinder is improved, so that the transportation requirement of large square quantity is fully met.
