[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0021] Traditional pressure testing equipment suffers from the following problems: Firstly, it relies on an electric motor to drive a hydraulic pump. The complex components of the hydraulic pump station increase the system's size and weight, resulting in poor overall compactness. Secondly, the large number of components makes installation, maintenance, and troubleshooting inconvenient. Thirdly, the motor operates inefficiently under light loads or intermittently, making the drive less flexible. Fourthly, purely pneumatic systems rely entirely on compressed air as an energy source, which has low energy density and limited output force. Furthermore, the compressibility of gas causes fluctuations in output force and speed, making control accuracy difficult to guarantee. Fifthly, when testing different pressure devices, traditional pressure testing equipment requires personnel to select appropriate booster pumps and sensors based on the operating conditions, performing replacement and assembly steps, resulting in slow testing efficiency. The accuracy of test results is also affected by the personnel's expertise. Sixthly, when multiple test procedures are required, traditional pressure testing equipment necessitates frequent operation, impacting testing efficiency. For example, in a test procedure of pressurization-holding-repressurization-holding-depressurization, personnel must operate the system after each procedure before proceeding to the next.

[0022] This application provides an ultra-high pressure hydraulic testing device that can solve the technical problems of complex components and insufficient driving flexibility in related technologies.

[0023] See Figure 1 , Figure 4 and Figure 8As shown, an ultra-high pressure hydraulic testing device provided in this application embodiment includes: a main body 1, which is equipped with an electrical control system, and a pressure testing piece 2 is also installed on one side of the main body 1 with the electrical control system; a gas-liquid booster system 3, which is installed on the main body 1, and includes a gas source tank 31, a hydraulic oil tank 32, a high-pressure gas-driven liquid booster pump 33, a pressure sensor, and hydraulic pipelines 34; the gas source tank 31 and the hydraulic oil tank 32 are both connected to the high-pressure gas-driven liquid booster pump 33, and the high-pressure gas-driven liquid booster pump 33... The pressure test piece 2 is connected via the hydraulic pipeline 34; a first solenoid valve 35 and a pressure regulating valve 36 are connected between the gas source tank 31 and the high-pressure gas-driven liquid booster pump 33, and a second solenoid valve 37 is connected between the hydraulic oil tank 32 and the high-pressure gas-driven liquid booster pump 33; the pressure sensor, the first solenoid valve 35, the pressure regulating valve 36, and the second solenoid valve 37 are all electrically connected to the electronic control system, and the pressure sensor is used to detect the gas source inlet pressure, the hydraulic output port pressure of the high-pressure gas-driven liquid booster pump 33, and the internal pressure of the hydraulic oil tank 32.

[0024] See Figures 1 to 3 As shown, the main body 1 of the equipment is provided with an electrical control system mounting position 11, located at the upper left of the main body 1, and a hydraulic oil source mounting position 12 is provided at the lower left of the main body 1. The air-hydraulic booster system 3 is installed at the hydraulic oil source mounting position 12, and the electrical control system is installed at the electrical control system mounting position 11. A test function area 13 is provided at the upper right of the main body 1, and the pressure test piece 2 is installed in the test function area 13. In this embodiment, a pressure sensor is installed at the air source inlet of the high-pressure gas-driven liquid booster pump 33, and another pressure sensor is installed at the hydraulic output port of the high-pressure gas-driven liquid booster pump 33 (i.e., the location connected to the hydraulic pipeline 34). A pressure sensor is also installed in the hydraulic oil tank 32. This allows the three pressure sensors to detect the air source inlet pressure of the high-pressure gas-driven liquid booster pump 33, the hydraulic output port pressure of the high-pressure gas-driven liquid booster pump 33, and the internal pressure of the hydraulic oil tank 32. The pressure detected by the three pressure sensors is fed back to the electronic control system. Based on the feedback pressure value, the electronic control system adjusts the opening of the first solenoid valve 35 and the second solenoid valve 37, and regulates the pressure regulating valve 36 to adjust the air source pressure and affect the hydraulic output port pressure of the high-pressure gas-driven liquid booster pump 33. The electronic control system forms a closed-loop circuit through pressure sensor feedback combined with actuator control. The actuators include the aforementioned first solenoid valve 35, second solenoid valve 37, and pressure regulating valve 36. The pressure sensors prevent blockage by detecting the internal pressure of the hydraulic oil tank 32. The electronic control system can control the opening degree, on / off state, and flow direction of the solenoid valve. In this embodiment, the hydraulic line 34 is preferably a high-pressure hose.

[0025] This embodiment employs a gas-liquid booster system 3, combining the advantages of both pneumatic and hydraulic systems. The built-in high-pressure gas-driven liquid booster pump 33 pressurizes the hydraulic oil to the required maximum pressure (0-60MPa) before use, eliminating the need for a hydraulic pump station. It operates using only an air source, hydraulic oil, the high-pressure gas-driven liquid booster pump 33, sensors, valves, and a small number of hydraulic lines 34. This reduces the system's size and weight, lowering equipment costs and installation space requirements. Its energy conversion efficiency (from pneumatic energy to hydraulic energy) is high during the pressurization process, making it particularly suitable for intermittent and impact loads. This solves the technical problems of complex components and inflexible drive in related pressure testing equipment.

[0026] Meanwhile, the gas-liquid booster system 3 utilizes Pascal's principle and the incompressibility of liquids to provide a very stable output force. The ratio of high-pressure gas to liquid booster pump 33 reaches 80:1. The system can precisely control pressure and displacement, making up for the shortcomings of limited output force and poor precision of pure pneumatic systems.

[0027] See Figure 8 As shown, in one embodiment, the high-pressure gas-driven liquid booster pump 33 is further connected in parallel with an overflow valve 38. In this embodiment, the overflow valve 38 is connected in parallel at the outlet of the high-pressure gas-driven liquid booster pump 33, and the overflow valve 38 is also electrically connected to the electronic control system for automatic pressure relief.

[0028] In some alternative embodiments, see Figure 4 As shown, the pressure test piece 2 has a hydraulic cavity, and one end of the pressure test piece 2 has a hydraulic interface 21. The pressure test piece 2 is connected to the hydraulic pipeline 34 through the hydraulic interface 21. The surface of the pressure test piece 2 is also provided with a pressure test interface 22, which is used to connect the device under test. In this embodiment, an internal thread is provided in the pressure test interface 22 for connecting the device under test. During testing, high-pressure hydraulic oil enters the hydraulic cavity of the pressure test piece 2 through the hydraulic pipeline 34 and enters the device under test through the pressure test interface 22 to test the pressure of the device under test. After the test is completed, the pressure is released.

[0029] Preferably, the pressure test piece 2 in this embodiment is made of seamless stainless steel tubing. For example, a seamless stainless steel tubing with an outer diameter of 63mm and a wall thickness of 15mm is used. Seamless stainless steel tubing has the characteristic of being weld-free, with outstanding advantages in structural integrity, good sealing performance and strength, which greatly reduces the possibility of micro-leakage caused by internal defects in the pipe, ensuring the accuracy of the test results.

[0030] Furthermore, in one embodiment, the surface of the pressure test piece 2 is provided with a plurality of pressure test interfaces 22, and the plurality of pressure test interfaces 22 are arranged in a row along the axis of the pressure test piece 2. See also Figure 4As shown in the figure, one optional method is to provide 10 pressure test interfaces 22 on the surface of the pressure test piece 2 so that 10 devices under test can be tested at the same time. In other embodiments, other numbers of pressure test interfaces 22 can be provided as needed.

[0031] In some alternative embodiments, see Figure 4 and Figure 7 As shown, a drain funnel 4 is provided below the hydraulic interface 21 on the main body of the device. In this embodiment, the drain funnel 4 is conical and its opening faces upward. When the pressure is released, the hydraulic oil can enter the drain funnel 4 for collection.

[0032] Furthermore, in one embodiment, a tool storage area 14 is provided below the drainage funnel 4, and a liquid storage box 5 is provided in the tool storage area 14. The drainage funnel 4 is connected to the liquid storage box 5 through a drainage pipe. See also Figure 6 and Figure 7 As shown, a liquid storage box 5 is provided in the middle of the tool storage area 14. This liquid storage box 5 is used to collect hydraulic oil that enters the drain funnel 4. The tool storage area 14 can also be used to store other tools.

[0033] See Figure 1 and Figure 4 As shown, in one embodiment, the electronic control system is located directly above the gas-liquid booster system 3, and the pressure test piece 2 is arranged side by side with the electronic control system. The main body 1 of the equipment also has a tool storage area 14, which is located directly below the pressure test piece 2 and is arranged side by side with the gas-liquid booster system 3. The ultra-high pressure hydraulic testing equipment in this embodiment is generally divided into four areas: the electronic control system installation position 11 area, the hydraulic oil source installation position 12 area, the testing function area 13, and the tool storage area 14. These four areas are arranged in pairs side by side and vertically, forming a square-shaped ultra-high pressure hydraulic testing equipment.

[0034] Furthermore, in one embodiment, the main body of the device 1 is provided with a test housing 15 in the test functional area 13, the pressure test piece 2 is located inside the test housing 15, the test housing 15 has a transparent protective shell 16, and a protective mesh 17 is provided inside the transparent protective shell 16. See also Figures 5 to 7 As shown, in this embodiment, a transparent protective shell 16 and a protective net 17 are provided in front of the test shell 15, and a transparent protective shell 16 and a protective net 17 are also provided behind the test shell 15. The use of a transparent protective shell 16 and a protective net 17 facilitates observation of the internal situation and ensures the safety of external personnel under high pressure.

[0035] Preferred, see Figure 2 , Figures 6 to 7As shown, a hinged cover 18 is provided on one side of the test housing 15. The hinged cover 18 is equipped with the transparent protective shell 16 and the protective net 17, and support rods 19 are connected to both sides of the hinged cover 18 to support the hinged cover 18 to a specific opening degree. In this embodiment, support rods 19 are provided on both the left and right sides of the hinged cover 18. The support rods 19 are installed to the main body 1 of the equipment. When the operator opens the hinged cover 18 to a certain angle, the support rods 19 can support the hinged cover 18 and keep the hinged cover 18 at that angle.

[0036] In this embodiment, the electrical control system of the ultra-high pressure hydraulic testing equipment is equipped with four test programs to meet the needs of different test methods. When the test meets the requirements, it can automatically stop the test and start a prompt buzzer indicating that the task has been completed. The test programs are: (1) constant speed pressure increase - burst; (2) constant speed pressure increase - pressure holding - burst; (3) constant speed pressure increase - pressure holding - pressure release; (4) constant speed pressure increase - pressure holding - constant speed pressure increase - pressure holding - until burst. Equipment technical parameters: test pressure parameters: 0-60MPa adjustable test pressure and pressure holding time; control accuracy: upper limit of test pressure value ±3%; pressure value resolution: 0.01MPa; pressure transmitter: test pressure sampling frequency 0.3 seconds; timing range: 0-32767s; timing accuracy: 1%; machine size: 3010*1310*750 (mm); power supply: 220V.

[0037] The ultra-high pressure hydraulic testing equipment provided in this embodiment can test the strength, tightness and other properties of high pressure equipment (test pressure below 60MPa). It provides the required high pressure through a built-in high pressure air-driven liquid booster pump, and monitors the internal pressure changes and test progress in real time through the platform's display interface. After the test is completed, it can automatically generate a test report.

[0038] Usage steps: (1) Install the device to be tested on the pressure test piece 2.

[0039] (2) Determine the pressure level, holding time and other test parameters of the pressure test according to the needs of the test project.

[0040] (3) Select from the four pre-set test procedures of the equipment to determine the specific test process.

[0041] (4) Select the determined test parameters and test procedures through the control interface.

[0042] (5) After the test starts, observe the pressure changes and subsequent pressure holding status in real time through the control interface. If there is an alarm or an unexpected event during the test, the test can be stopped immediately by pressing the emergency button.

[0043] (6) After the pressure holding is completed, the equipment will automatically release the pressure.

[0044] (7) After the pressure is released, remove the equipment and test the next set of equipment.

[0045] This ultra-high pressure hydraulic testing equipment uses configuration control software. The system automatically selects the required high-pressure air-driven liquid booster pump and sensor according to the test pressure to ensure the accuracy of test data and avoid personnel selection errors. The test program is pre-set and can realize four different test processes. The test platform has the functions of dynamic display and automatic recording and saving of test number, pressure, and test waveform, which is convenient for querying and printing. After the test, the equipment can automatically generate a test report. These designs greatly improve the accuracy and efficiency of the test.

[0046] This ultra-high pressure hydraulic testing equipment adopts a gas-liquid booster system 3, which combines the driving flexibility of a pneumatic system with the output stability of a hydraulic system. It has a simplified structure and the advantages of being lightweight, easy to install and maintain. Its control accuracy can reach 3% of the upper limit of the test pressure value.
