[0002] A hydraulic power unit is a hydraulic source device or a hydraulic device including control valves, consisting of a hydraulic pump, a drive motor, an oil tank, directional valves, throttle valves, and relief valves. It supplies oil according to the flow direction, pressure, and flow rate required by the drive device. It is suitable for various machines where the drive device and the hydraulic power unit are separate. By connecting the hydraulic power unit to the drive device (cylinder or motor) with oil pipes, the hydraulic system can achieve various specified actions.

[0003] Existing hydraulic power unit oil supply devices often suffer from energy waste during operation. For example, under certain working conditions, the required oil volume and pressure of the hydraulic system vary, but traditional oil supply devices typically operate at a constant power, unable to flexibly adjust according to actual needs, resulting in the waste of excess energy.

[0004] Therefore, it is necessary to provide an energy-saving oil supply device for hydraulic stations to solve the above-mentioned technical problems. Utility Model Content

[0017] Please see Figures 1-4 One embodiment provided by this utility model: An energy-saving oil supply device for a hydraulic station, comprising: A base frame 1 is provided. An oil tank 4 is fixedly installed on one side of the top of the base frame 1. A drive motor 2 is fixedly installed on the top of the base frame 1. An oil pump 3 is provided at the drive end of the drive motor 2. An output pipe 6 is fixedly connected between the oil inlet of the oil pump 3 and the oil tank 4. An oil outlet pipe 20 is fixedly connected to the oil outlet of the oil pump 3. A limit frame 13 is fixedly installed on the other side of the top of the base frame 1. An oil outlet connector 12 is fixedly installed on the front side of the top of the limit frame 13. The oil outlet connector 12 is fixedly connected to one end of the oil outlet pipe 20. A pressure sensor 14, a flow sensor 15, and a proportional control valve 16 are respectively installed on the oil outlet pipe 20; A recovery pipe 7 is installed on the rear side of the top of the oil tank 4, and a recovery connector 11 is fixedly installed on the rear side of the top of the limit bracket 13. A conduit 10 is fixedly installed at one end of the recovery connector 11, and a filter box 8 is fixedly installed between the conduit 10 and the recovery pipe 7.

[0018] A sealing plate 19 is provided on the top of the filter box 8. An installation opening 21 is provided on the sealing plate 19. A symmetrically distributed positioning groove 22 is provided on the inner wall of the filter box 8. A filter screen plate 18 is slidably inserted into the installation opening 21 and is slidably inserted into the positioning groove 22. A cover plate 17 is fixedly installed on the top of the filter screen plate 18.

[0019] In one embodiment, the cover plate 17 is fixedly installed on the top of the sealing plate 19 by bolts, and the sealing plate 19 is fixedly installed on the top of the filter box 8 by bolts, which facilitates disassembly and installation and makes it easier to clean and maintain the filter box 8 and the filter screen 18.

[0020] In one preferred embodiment, a controller 5 is fixedly installed on the front side of the top of the base frame 1, which facilitates centralized control of the device and improves ease of use.

[0021] In one embodiment, sealing gaskets are provided at the connection between the top of the filter box 8 and the bottom of the sealing plate 19, and at the connection between the bottom of the cover plate 17 and the top of the sealing plate 19, which can enhance the sealing effect, prevent hydraulic oil leakage, and ensure the normal operation of the filtration and circulation system.

[0022] In one preferred embodiment, a support frame 9 is fixedly installed between the bottom of the filter box 8 and the top of the base frame 1 to support and fix the filter box 8, enhance its stability, and ensure that the filtration work is carried out normally.

[0023] The working principle of this utility model is as follows: The entire device is controlled by controller 5. Since the equipment matched with controller 5 is commonly used in the industry, its electrical connections and specific circuit structure are existing common knowledge and will not be described in detail here. In use, the recovery connector 11 and the oil outlet connector 12 are connected to the external hydraulic system. When oil needs to be supplied to the hydraulic system, controller 5 controls the drive motor 2 to start operating. The drive motor 2 drives the oil pump 3 to work. The oil pump 3 draws hydraulic oil from the oil tank 4 through the output pipe 6 and delivers it to the oil outlet pipe 20. The pressure sensor 14 and flow sensor 15 installed on the oil outlet pipe 20 monitor the quantity and pressure of the hydraulic oil entering the hydraulic system through the oil outlet connector 12 in real time. Based on the signals fed back by the pressure sensor 14 and the flow sensor 15, the controller 5 accurately analyzes the current oil quantity and pressure required by the hydraulic system, and then regulates the speed of the drive motor 2 and the opening of the proportional regulating valve 16, so that the oil quantity and pressure output by the oil pump 3 are precisely matched with the actual needs of the hydraulic system, effectively avoiding the energy waste problem caused by the constant power operation of the traditional oil supply device, and significantly improving energy utilization efficiency.

[0024] During the oil return process, the hydraulic oil in the hydraulic system flows back to the inside of the conduit 10 through the recovery connector 11 and enters the filter box 8 under the guidance of the conduit 10. The filter screen 18 located in the filter box 8 filters the returned hydraulic oil to ensure the quality of the hydraulic oil circulation. When it is necessary to clean and maintain the filter screen 18 later, the connecting bolts between the cover plate 17 and the sealing plate 19 can be directly removed while the device is stopped. Then, the filter screen 18 can be directly pulled out from the filter box 8 through the installation opening 21 through the cover plate 17, which facilitates the cleaning and maintenance of the filter screen 18. In addition, after removing the connecting bolts between the sealing plate 19 and the filter box 8, the sealing plate 19 can be directly removed from the top of the filter box 8, which facilitates the cleaning and maintenance of the inside of the filter box 8. By setting the filter screen 18 and the sealing plate 19 with detachable characteristics, the subsequent cleaning and maintenance of the filter components is greatly facilitated, effectively reducing the difficulty of cleaning and maintenance and possessing high practicality.
