[0003] Existing hydraulic flushing systems have limitations during operation. First, the fluid velocity in the pipeline is difficult to control precisely, making it difficult for impurities to be discharged quickly with the fluid flow. Second, the flushing path planning lacks scientific basis, often resulting in flushing blind spots that require repeated flushing. Third, the flushing system uses a fixed pressure and flow output method, which cannot achieve real-time control and cannot meet the demand for large flow rates at the same time, thus failing to meet the needs of complex flushing applications. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-3 As shown, this utility model provides a technical solution: a high-performance hydraulic flushing system, including an oil tank 17 and a remote relief valve 7. A double gear pump 2 is installed on the top of the oil tank 17. A first motor 1 is installed on the double gear pump 2. A first relief valve 4 and a second relief valve 5 are connected to the side of the double gear pump 2. A solenoid directional valve 6 is installed at the control port of the first relief valve 4 and the second relief valve 5. A first high-pressure ball valve 8 and a second high-pressure ball valve 9 are connected to the double gear pump 2. The first high-pressure ball valve 8 is located below the second high-pressure ball valve 9. A connecting pipe is installed on the second high-pressure ball valve 9. A primary return oil filter 10 is installed in the middle section of the connecting pipe. One end of the connecting pipe is connected to an air cooler 11. A secondary return oil filter 12 is connected to the side of the air cooler 11 through a pipe. The secondary return oil filter 12 is located on the top of the oil tank 17. A one-way valve 3 is connected to the bottom side of the double gear pump 2.

[0023] In this embodiment, a remote relief valve 7 is installed on the system operation panel. After the pressure of the first relief valve 4 and the second relief valve 5 in the system is set, if the output pressure needs to be adjusted again, there is no need to adjust the first relief valve 4 and the second relief valve 5 again. The remote relief valve 7 can be adjusted directly on the operation panel to adjust the required output pressure. By using remote control, flushing conditions can be provided more quickly according to the required flow rate, solving the problem that previous hydraulic flushing systems only had fixed pressure and flow output modes. This provides higher quality equipment for industries in need. This significantly improves flushing efficiency. When the flushing flow rate requires an input flow rate of 0-300 L / min, the pressure oil from the double gear pump 2 passes through the second relief valve 5, which is set to a pressure of 5 MPa. The first relief valve 4 is set to a pressure of 3 MPa. When the system output pressure is 5 MPa, the first relief valve 4 overflows back to the oil tank 17. At this time, only the second relief valve 5 outputs a pressure of 5 MPa, so the system supply flow rate is only 300 L / min. Then, it passes through the first high-pressure ball valve 8 to provide a flushing flow rate of 0-300 L / min to the equipment requiring flushing. When the required flushing flow rate is 0-600 L / min, the pressurized oil from the double gear pump 2 passes through the second relief valve 5 and the first relief valve 4. The pressure of the first relief valve 4 is set to 3 MPa. The oil then passes through the check valve 3 and merges with the pressurized oil from the double gear pump 2. Finally, it passes through the first high-pressure ball valve 8 to provide a flow rate of 600 L / min to the equipment requiring flushing. This flexible pressure control controls the flow output, solving the problem of traditional hydraulic flushing systems having only fixed pressure and flow outputs, thus providing significant market demand for complex flushing environments. An electromagnetic reversing valve 6 is installed at the control ports of the first overflow valve 4 and the second overflow valve 5. When the equipment to be flushed needs to be flushed multiple times or when pressure changes are required, the electromagnets YV1 and YV2 of the electromagnetic reversing valve 6 can be energized to switch left and right to achieve the purpose of pressure increase and depressurization, thereby realizing pulse flow output. Each reversal can generate pulse data, which can be used to record and set the number of flushing times. Pulse flushing not only solves the previous single flushing mode, but also generates greater turbulence, which can remove impurities in the pipeline more quickly, greatly improving flushing efficiency and reducing labor costs.

[0024] Example 2: Figures 1-3 As shown, a forward and reverse gear pump 14 is installed on the oil tank 17, a second motor 13 is installed on the forward and reverse gear pump 14, and a return oil filter 15 and a suction oil filter 16 are symmetrically arranged on one side of the forward and reverse gear pump 14.

[0025] In this embodiment, the oil transfer device is equipped with a second motor 13, a forward and reverse gear pump 14, an oil suction filter 16, and an oil return filter 15. It can provide oil injection / extraction functions according to different needs. The integrated oil transfer function provides a more convenient way for customers to meet their needs, greatly reducing operating costs and improving flushing efficiency. After flushing, the fluid will undergo primary filtration after passing through the second high-pressure ball valve 9, and then through the primary return oil filter 10 to filter out slightly larger impurities. After that, it will be cooled by the air cooler 11 to prevent the oil temperature from being too high and damaging the components. Finally, it will pass through the secondary return oil filter 12 before returning to the oil tank 17. After layer-by-layer filtration, the number of impurities entering the oil tank is greatly reduced, providing high-quality fluid for the system's circulating flushing, ensuring that the components are not damaged, and improving the system's service life. The cooling method of the air cooler 11 solves the problem of high heat generation and serious energy loss.

[0026] The working principle of this embodiment is as follows: In use, a remote relief valve 7 is first installed on the system operation panel. After the pressure of the first relief valve 4 and the second relief valve 5 in our system is set, if the output pressure needs to be adjusted, there is no need to adjust the first relief valve 4 and the second relief valve 5 again. The remote relief valve 7 can be adjusted directly on the operation panel to adjust the required output pressure. When the flushing flow rate requires an input flow rate of 0-300 L / min, the pressure oil from the double gear pump 2 passes through the second relief valve 5. The pressure of the second relief valve 5 is set to 5 MPa, while the first relief valve... The set pressure of valve 4 is 3MPa. When the system output pressure is 5MPa, the first relief valve 4 overflows back to the oil tank 17. At this time, only the second relief valve 5 outputs a pressure of 5MPa, so the system supply flow rate is only 300L / min. Then, it passes through the first high-pressure ball valve 8 to provide 0-300L / min of flushing conditions to the equipment that needs to be flushed. When the flushing flow rate requires an input flow rate of 0-600L / min, the pressure oil from the double gear pump 2 passes through the second relief valve 5 and the first relief valve 4. The pressure of the first relief valve 4 is set to 3MPa, and it passes through the check valve 3 and the double gear pump 17. The pressurized oil from gear pump 2 is combined and passes through the first high-pressure ball valve 8 to provide a flow rate of 600L / min to the equipment to be flushed. Electromagnetic reversing valves 6 are installed at the control ports of the first overflow valve 4 and the second overflow valve 5. When the equipment to be flushed requires multiple flushes or pressure changes, the electromagnets YV1 and YV2 of the electromagnetic reversing valve 6 are energized to switch left and right, achieving pressure increase and decrease to realize pulse flow output. Each reversal generates pulse data, which is used to record and set the flushing count. The oil transfer device is equipped with a second motor 13, which can rotate in both directions. The gear pump 14, suction oil filter 16, and return oil filter 15 can provide oil injection / extraction functions according to different needs. The integrated oil transfer function provides a more convenient way for customers to meet their needs. After flushing, the fluid will undergo primary filtration after passing through the second high-pressure ball valve 9, and then pass through the primary return oil filter 10 to filter out slightly larger impurities. After that, it will be cooled by the air cooler 11 to prevent the oil temperature from being too high and damaging the components. Finally, it will pass through the secondary return oil filter 12 before returning to the oil tank 17. After layers of filtration, the number of impurities entering the oil tank is greatly reduced, providing high-quality fluid for the system's circulating flushing.
