[0002] A hydraulic station, also known as a hydraulic pump station, generally drives an oil pump to rotate by an electric motor. After the oil pump sucks oil from the fuel tank and then pressurizes the oil, it converts mechanical energy into the pressure energy of hydraulic oil. The hydraulic oil flows out through an integrated block, and then through a hydraulic valve to achieve the adjustment of direction, pressure, and flow rate. After that, it is transmitted to the oil cylinder or oil motor of the hydraulic machinery through an external pipeline, thereby controlling the change of the direction of the hydraulic motor, the magnitude of the force, and the speed, and driving various hydraulic machinery to do work. It is used in many fields and provides convenience for production and operation.

[0003] During the use of the existing hydraulic station, due to the long pipeline design, the pipeline is bent when connected, the length of the pipeline conveying path is extended, and a large amount of energy consumption is required to convey hydraulic oil, resulting in an increase in the electric energy consumption of the hydraulic station. At the same time, when the filter is blocked and needs to be cleaned, the hydraulic station needs to be shut down for replacement and cleaning, and the energy consumption increases during the process of starting and stopping the hydraulic station.

[0004] Therefore, those skilled in the art provide an energy-saving hydraulic station to solve the problems raised in the above background technique. Content of the Utility Model

[0009] As a further scheme in the utility model, the filter is interconnected with the filter cartridge through the shunt pipe, and the shunt pipe and the filter cartridge are symmetrically arranged left and right with respect to the symmetry center line of the filter.

[0010] As a further solution in the present utility model, a connecting pipe is connected to one end of the conveying pipe away from the filter cartridge, and a reversing valve is installed at one end of the connecting pipe.

[0012] As a further solution in the present utility model, the output end of the reversing valve is connected to a second pipe, and a throttle valve is installed at one end of the second pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Two filter cartridges are provided on the filter. The two filter cartridges are alternately switched for use.

[0015] 2. A booster pump is installed on the conveying pipe to increase the lifting pressure inside the pipeline by using the booster pump, avoiding the influence of the pipeline length and shape on the conveying efficiency of the hydraulic oil, resulting in greater energy consumption, and being beneficial to achieving energy conservation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 , an energy-saving hydraulic station is provided in an embodiment of the present utility model, including: a mounting table 1, a driving motor 2 is installed above the mounting table 1, and an oil tank 3 is installed at the output end of the driving motor 2. A pipe 4 is connected above the oil tank 3. A filter 5 is installed at one end of the pipe 4 away from the oil tank 3. Shunt pipes 14 are connected to both sides of the filter 5, and a control valve 15 is installed on the surface of the shunt pipe 14. The output end of the shunt pipe 14 is installed with a filter cartridge 11, and a delivery pipe 12 is connected to the bottom of the filter cartridge 11. A booster pump 13 is installed on the surface of the delivery pipe 12.

[0023] The oil tank 3 is interconnected with the filter 5 through the pipe 4, and an oil inlet 16 is provided between the pipe 4 and the filter 5. The filter 5 is interconnected with the filter cartridge 11 through the shunt pipe 14, and the shunt pipe 14 and the filter cartridge 11 are symmetrically arranged left and right with respect to the symmetry center line of the filter 5;

[0024] Specifically, through the setting of the oil inlet 16 on the surface of the filter 5, the hydraulic oil in the oil tank 3 is filtered to avoid the problem of pipeline blockage. During use, the two filter cartridges 11 are alternately switched, and the control valve 15 is used to control the opening and closing of the shunt pipes 14 on both sides of the filter 5. When replacing the filter cartridge 11, one group of control valves 15 is closed, and the other shunt pipe 14 and the filter cartridge 11 operate normally for filtration, without the need to shut down and restart the equipment, which is beneficial to energy saving.

[0025] One end of the delivery pipe 12 away from the filter cartridge 11 is connected to a connecting pipe 6. A reversing valve 7 is installed at one end of the connecting pipe 6. A return pipe 8 is connected to one side of the reversing valve 7, and a relief valve 9 is installed on the surface of the return pipe 8. The output end of the reversing valve 7 is connected to a pipe 17, and a throttle valve 10 is installed at one end of the pipe 17;

[0026] Specifically, through the setting of the return pipe 8 and the relief valve 9, when the system pressure increases, the flow demand will decrease. At this time, the relief valve 9 opens, allowing the excess flow to overflow back to the oil tank 3 to ensure the inlet pressure of the relief valve 9, improve energy saving, and at the same time cooperate with the throttle valve 10 for use to save hydraulic oil and reduce losses.

[0027] The working principle of the present utility model is as follows: When using the present utility model, the driving motor drives the hydraulic pump to rotate. The hydraulic pump sucks hydraulic oil from the fuel tank 3, and the hydraulic oil enters the filter 5 through the first pipeline 4 for filtration. A set of control valves 15 is closed, and a set of filter cartridges 11 is used for filtration. The filtered hydraulic oil is sent to the reversing valve 7 through the delivery pipe 12 and the connecting pipe 6. During the delivery process, the booster pump 13 installed on the delivery pipe 12 will increase the fluid pressure and improve the delivery efficiency. The reversing valve 7 is used to reverse the delivery flow path and is delivered through the second pipeline 17. The throttle valve 10 is used to control the cross-sectional area of the fluid, saving flow while increasing the flow rate. Secondly, when the system pressure increases, the overflow valve 9 is opened, and the return pipe 8 will return the excess hydraulic oil back into the fuel tank 3 to ensure the inlet pressure of the overflow valve 9. Thirdly, when replacing the filter cartridge 11, the control valve 15 is closed, and another set of control valves 15 is opened to switch to another set of filter cartridges 11. The other set of shunt pipes 14 and the filter cartridges 11 operate normally for filtration without the need to shut down and restart the hydraulic station system.

[0028] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
