DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0013] The present application relates to a dual output submerged arc furnace hydraulic station, such as Figure 1-5 As shown, the hydraulic station includes an oil tank 4 for storing hydraulic oil and having functions such as cooling and filtering. A tank cover 3 detachably connected to the oil tank 4 is arranged on the top of the oil tank 4. A driving assembly for providing a power source and having a seismic isolation effect is arranged at one end of the upper part of the tank cover 3. A pump body assembly driven by the pump body assembly and having a dual output function is arranged on one side of the driving assembly. In order to realize the dual output operation of the hydraulic station, a valve body assembly 8 connected to the pump body assembly and having a multi-functional oil adjustment function is also arranged on the upper part of the tank cover 3.

[0014] The driving assembly includes a motor 2, a base 5, and a vibration isolator 6. The motor 2 is arranged on the upper part of the box cover 3 to provide power. In order to facilitate the connection between the motor 2 and the box cover 3, a base 5 for connecting with the box cover 3 is arranged directly below the motor 2. The motor 2 will vibrate during operation. In order to reduce the impact of the vibration on the oil in the oil tank 4, a vibration isolator 6 connected to the base 5 and having a shock-absorbing effect is arranged on the upper part of the box cover 3.

[0015] The pump body assembly includes a hydraulic pump 1, an oil pipe 11, and a filter 12. The hydraulic pump 1 is arranged on the upper part of the tank cover 3 and is connected to the motor 2 through a coupling. An oil pipe 11 that penetrates into the oil tank 4 is arranged on one side of the hydraulic pump 1. In order to prevent impurities contained in the oil from causing blockage of the hydraulic pump 1 or the valve body assembly 8, a filter 12 with an oil filtering function is added to one end of the oil pipe 11. In order to realize the dual output operation of the hydraulic station, the hydraulic pump 1 is a double pump with two sets of independent oil outlets that do not affect each other.

[0016] The valve body assembly 8 includes a valve block 17, a plate-type one-way valve 18, an electromagnetic reversing valve 14, a one-way throttle valve 20, an electro-hydraulic reversing valve 15, a hydraulic one-way valve 21, an unloading valve 16, and an electromagnetic overflow valve 19. The valve block 17 is arranged on the upper part of the box cover 3 and inserted into the box body through a plurality of steel pipes. A plate-type one-way valve 18 for coordinated communication is horizontally placed on the upper part of the valve block 17. The upper part of the plate-type one-way valve 18 is sequentially connected with an electromagnetic reversing valve 14 arranged vertically therewith and used to switch the flow direction of the hydraulic oil, a one-way throttle valve 20 for controlling the flow of the hydraulic oil, an electro-hydraulic reversing valve 15 for realizing complex flow switching and control logic, and a valve for allowing the hydraulic oil to flow under specific conditions. A reverse flow hydraulically controlled one-way valve 21 and a relief valve 16 which automatically opens to unload oil when the system reaches a set pressure, wherein the electromagnetic reversing valve 14 and the one-way throttle valve 20 are arranged side by side, and the electro-hydraulic reversing valve 15 and the hydraulically controlled one-way valve 21 are arranged side by side, and an electromagnetic overflow valve 19 which is connected to the valve block 17 and controls the maximum working pressure of the system and opens quickly in case of overpressure is also arranged on the side of the valve block 17. Therefore, by integrating multiple valves into the upper part of a valve block 17, the complexity and space occupation of the valve body assembly 8 are effectively reduced, and thanks to the arrangement of the unloading valve 16 and the electromagnetic overflow valve 19, the safe operation of the valve body assembly 8 under relatively stable pressure can be ensured.

[0017] When in use, the hydraulic pump 1 is driven by the motor 2, and then the hydraulic pump 1 uses the plate-type one-way valve 18, the electromagnetic reversing valve 14, the one-way throttle valve 20, the electro-hydraulic reversing valve 15, the hydraulically controlled one-way valve 21, the unloading valve 16, and the electromagnetic overflow valve 19 integrated on the upper part of the valve block 17 to perform oil reversing adjustment, flow adjustment, and pressure adjustment operations according to actual working conditions, so that the hydraulic station can achieve dual-output operation in a stable state, effectively simplifying the configuration mode of one furnace and one station.
