DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The dual-output hydraulic station of the present invention includes a drive motor 1, a central valve block 3, a duplex hydraulic pump 5 and an oil tank 8 connected in sequence; the central valve block 3 is connected to the first relief valve 4, the duplex hydraulic pump 5, the oil tank 8, the transition valve block 11, the cushion block 12, the hydraulic plate valve 13, the one-way valve 14, and the second relief valve 15; the rear pump oil outlet of the duplex hydraulic pump 5 is connected to the oil circuit of the central valve block 3 through a joint 6 and a steel pipe 9; a liquid level switch 7 is provided on the oil tank 8.

[0023] The drive motor 1 of the present invention is connected to the duplex hydraulic pump 5 via a coupling 2 that passes through the center valve block 3. The oil from the rear pump outlet of the duplex hydraulic pump 5 is pumped to the oil circuit of the center valve block 3 via a connector 6 and a steel pipe 9. The center valve block 3 is connected to the oil tank 8 via fastening screws 10. The center valve block 3 is also connected to the transition valve block 11 and the spacer 12 via fastening screws 10. The center valve block 3 is also connected to the hydraulic plate valve 13 via fastening screws 10. The first relief valve 4, the check valve 14, and the second relief valve 15 are fastened to the center valve block 3 via threads. The liquid level switch 7 is also threaded onto the oil tank 8.

[0024] like Figure 4 The driving motor 1 of the utility model is connected to the double hydraulic pump 5 through the coupling 2 passing through the central valve block 3 to realize the pumping of oil, wherein the front pump oil outlet of the double hydraulic pump 5 is directly in contact with the connection surface of the central valve block 3 on the front cover surface, so that the oil is directly output to the hydraulic system; the rear pump oil outlet of the double hydraulic pump 5 is on the rear cover surface, and is connected to the central valve block 3 using a joint 6 and a steel pipe 9, so that the oil is output to another hydraulic system of the system.

[0025] The one-way valve 14 of the present invention is a threaded cartridge valve, which is screwed directly into the central valve block 3 and mainly prevents the oil from flowing back and causing the gear pump to rotate in reverse.

[0026] The first relief valve 4 and the second relief valve 15 of the present invention are threaded cartridge valves, which are screwed directly into the central valve block 3 to control the maximum pressure of the system according to the needs of the hydraulic system and play a role in protecting the system.

[0027] The hydraulic plate valve 13 of the present invention is a plate-type hydraulic valve, which is fastened to the transition valve block 11 with its own fastening screws. Plate-type hydraulic valves of different principles can be selected according to the hydraulic principle.

[0028] The liquid level switch 7 of the present invention is a threaded plug-in type, which is screwed directly into the oil tank interface. The float position set by the liquid level switch stops the system operation when the oil in the oil tank 8 is insufficient.

[0033] Space optimization: Installing multiple traditional hydraulic stations in a limited space is not only costly but also difficult to maintain. The dual-output hydraulic station integrates two or more hydraulic circuits into one device through integrated design, significantly saving installation space and making the equipment layout more compact and reasonable.
