Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0021] The following is a reference to the appendix. Figure 1 To be continued Figure 4 The present invention describes a mobile hydraulic measurement and control system.

[0022] like Figure 1 and Figure 4As shown, the mobile hydraulic measurement and control system of this invention includes a mobile skid, a hydraulic system, an electrical control system, and pipeline connection components. The hydraulic system includes a water tank 55, a pump set, a filter assembly, a valve assembly, and a pressure monitoring assembly. The pump set includes a motor-driven hydraulic pump 52 and a pneumatically driven hydraulic pump 53. The electrical control system includes a touch screen 51, control software, an electrical control box 54, and sensors. The pipeline connection components include rigid pipes, flexible pipes, and interfaces. The platform is moved to the test site, and the casters are locked to fix the platform to the ground. Test medium is then injected into the water tank 55, and the volume is confirmed by the level sensor 43. Next, the device under test is connected to the platform's outlet hose. The test mode is selected via the touch screen 51, and parameters such as test pressure and holding time are set. The motor-driven hydraulic pump 52 is started to inject test medium into the device under test and increase the pressure. When the pressure reaches 2000 psi, the system automatically stops the motor-driven hydraulic pump 52. Then, the first manual shut-off valve 1 is opened to allow the driving air to pass through the first filter 2 to filter the driving air, and the first pressure regulating valve 3 adjusts the driving air pressure. The small, first pressure gauge 4 detects the driving air pressure, and the one-way throttle valve 6 prevents driving air from flowing in and starts the pneumatic-driven liquid pump 53 to continue pressurizing to the set pressure. When the set pressure is reached, the pneumatic-driven liquid pump 53 will stop working, and the pneumatic needle valve will also close, thus putting the system into a pressure holding state. This will cause the timer to start counting, and the pressure transmitter can monitor the pressure change in real time, thus synchronizing the data to the control software and generating a curve. When the pressure holding time ends, the pneumatic needle valve will automatically open to release pressure, reducing the pressure to a safe range before closing it. After the platform test is completed, the software will automatically generate a PDF test report, which includes pressure, time curves, temperature data, etc., and can be printed out in both Chinese and English for easy observation of the test data by the user.

[0023] In a preferred embodiment, the hydraulic control system includes a manual state, an automatic state, a manual state or an automatic state, and the switching between the manual state and the automatic state can be completed by a manual-automatic switching button, and an emergency stop switch is provided to ensure safety.

[0024] When in manual mode, the drive line includes a first shut-off valve 1, a first filter 2, a first pressure regulating valve 3, a first pressure gauge 4, and a one-way throttle valve 6; the low-pressure line includes a fourth pressure gauge 22 and a fourth manual shut-off valve 20; the medium-pressure line includes a fifth pressure gauge 29 and a sixth manual shut-off valve 28; the high-pressure line includes a sixth pressure gauge and an eighth manual shut-off valve 36; the drive line supplies drive air to the first booster pump 7 to increase the pressure of the first booster operation; the low-pressure line outputs a low-pressure output pressure of 2000~10000psi; the medium-pressure line outputs a medium-pressure output pressure of 10000~15000psi; and the high-pressure line outputs a high-pressure output pressure of 15000~22500psi.

[0025] When in automatic mode, the drive line includes a first manual shut-off valve 1, a first filter 2, a first pressure regulating valve 3, a first pressure gauge 4, a first solenoid valve 5, a third check valve 44, and second solenoid valves 45-50; the low-pressure line includes a first pneumatic shut-off valve 13, a second pressure transmitter 15, and a second pneumatic shut-off valve 19; the medium-pressure line includes a third pneumatic shut-off valve 21, a third pressure transmitter 23, and a fourth pneumatic shut-off valve 27; the high-pressure line includes a fifth pneumatic shut-off valve 32, a fourth pressure transmitter 30, and a sixth pneumatic shut-off valve 35; the drive line serves as the power supply to the first pneumatic shut-off valve 13, the second pneumatic shut-off valve 19, the third... Pneumatic shut-off valves 21, 27, 32, and 35, and the first booster pump 7 supply driving air, which enables the first and second pneumatic shut-off valves 13, 19, 21, 32, and 35 to open and close, and the first booster pump 7 to pressurize. The low-pressure pipeline serves as the low-pressure output line, with an output pressure of 2000~10000psi; the medium-pressure pipeline serves as the medium-pressure output line, with an output pressure of 10000~15000psi; and the high-pressure pipeline serves as the high-pressure output line, with an output pressure of 15000~22500psi.

[0026] The pressure gauge provides operators with a visual indication of the real-time pressure, while the pressure transmitter transmits the pressure data to an external electrical control system. The pressure regulating valve can be operated manually or automatically.

[0027] Furthermore, such as Figure 1 and Figure 3 As shown, in the direction from the outlet of water tank 55 to the test port, the pipeline is sequentially equipped with a ninth manual shut-off valve 42, a sixth filter 41, a second booster pump 37, a second check valve 38, a fourth safety valve 39, a first booster pump 7, a second pressure gauge 8, a first pressure transmitter 9, a second manual shut-off valve 10, a second filter 11, and a first check valve 12. To the low-pressure test port, the pipeline is sequentially equipped with a first pneumatic shut-off valve 13, a third pressure gauge 14, a second pressure transmitter 15, and a third manual shut-off valve 16. The low-pressure relief pipeline is equipped with a third filter 17, a first safety valve 18, a second pneumatic shut-off valve 19, and a fourth manual shut-off valve 20. To the medium-pressure test port, the pipeline is sequentially equipped with a third pneumatic shut-off valve 21, a fourth pressure gauge 22, a third pressure transmitter 23, and a fifth manual shut-off valve 24.

[0028] The medium-pressure relief pipeline is equipped with a fourth filter 26, a second safety valve 25, a fourth pneumatic shut-off valve 27, and a sixth manual shut-off valve 28. The high-pressure test port is sequentially equipped with a fifth pneumatic shut-off valve 32, a fifth pressure gauge 29, a third pressure transmitter 23, and a seventh manual shut-off valve 31. The high-pressure relief pipeline is equipped with a fifth filter 34, a third safety valve 33, a sixth pneumatic shut-off valve 35, and an eighth manual shut-off valve 36. The low-pressure test port supplies test pressure to the low-pressure test template; the medium-pressure test port supplies test pressure to the medium-pressure test template; and the high-pressure test port supplies test pressure to the high-pressure test template.

[0029] For ease of monitoring and safety considerations, a sixth filter 41 is installed at the outlet of water tank 55. The first, second, and third pressure relief pipes are all equipped with a third filter 17, a fourth filter 26, and a fifth filter 34. The first, second, and third pressure relief pipes are also equipped with a first safety valve 18, a second safety valve 25, and a third safety valve 33. The sixth filter 41 at the outlet of water tank 55 filters out impurities flowing out of water tank 55, preventing impurities from entering the pipes and damaging subsequent pump units and valves. The third filters 17, 26, and 34 filter impurities in the test template in the pressure relief pipes, protecting the second pneumatic shut-off valve 19, the fourth pneumatic shut-off valve 27, and the sixth pneumatic shut-off valve 35. The first safety valve 18, the second safety valve 25, and the third safety valve 33, installed in the first, second, and third pressure relief pipes, prevent the pressure in the low, medium, and high output pipes from exceeding the maximum output pressure of the pipes.

[0030] Furthermore, such as Figure 1 As shown, the top of the water tank 55 has a water inlet and a manhole, the bottom of the water tank 55 has a drain valve 40, and a liquid level thermometer is installed on the side of the water tank 55. The water tank 55 is made of 316 stainless steel with a thickness greater than 2mm and an effective volume of 400L. By installing a liquid level thermometer, a water inlet, a manhole, and a drain outlet inside the water tank 55, it can be used to ensure the storage and monitoring of test media, making it versatile and accurate.

[0031] Specifically, the filtration assembly includes a high-pressure filter, which is installed at the outlet of the pump unit. By setting the filtration accuracy of the high-pressure filter to be no less than 5μm, the cleanliness level of the water source can be maintained at a level no lower than SAEAS4059 Class 6B-F, effectively preventing contamination of the tested equipment or affecting the test results, thus ensuring its cleanliness and hygiene.

[0032] Furthermore, such as Figure 1 and Figure 2 Figure 2As shown, the pressure monitoring component includes a pressure gauge and a pressure transmitter. The pressure gauge is selected with a range of 0~30000psi and an accuracy of ±0.5%FS. The pressure transmitter is selected with a range of 0~30000psi and an output of 4~20mA signal. The range and accuracy comply with API 6A specifications, thus enabling it to be used for real-time pressure monitoring, making it versatile and compliant.

[0033] Preferably, the electronic control system also includes a printer, which is fixedly installed in the operating room. The printer can be used to print bilingual (Chinese and English) test reports, and its storage capacity is greater than 1TB. This not only makes the software interface clearer but also adapts to devices with different resolutions, avoiding performance issues due to insufficient memory. The reserved physical network or NB-IoT interface facilitates future data transmission and remote monitoring, making it practical and adaptable.

[0034] The hydraulic system is equipped with a main circuit and at least three high-pressure regulating circuits. After passing through the main circuit, the three high-pressure regulating circuits can set or limit the maximum working pressure of the hydraulic system, ensuring stable operation of the system under high-pressure conditions. The pneumatic needle valve is used for isolation, pressure holding and pressure relief, and a manual needle valve is provided as a backup, so that it can achieve multi-level pressure changes in different working stages, making it stable and versatile.

[0035] Meanwhile, the low-pressure section of the rigid tubing uses a double-ferrule connection, while the external connection uses a high-pressure hydraulic hose. The rigid tubing is made of 316SS stainless steel. The low-pressure section uses a double-ferrule connection, and the high-pressure section uses an autoclave design. The external connection uses a 30-meter long high-pressure hydraulic hose with a pressure rating of ≥30,000 psi and a diameter of ≥10 mm. The connector is an AUTOCLAVE 9 / 16HP male, which can be adapted to meet specific needs, ensuring connectivity and compatibility.

[0036] Safety valves and check valves are installed on the main circuit. The safety valves automatically open and release pressure when the system is overpressurized, thus protecting the equipment and the device under test. The check valves only allow fluid to flow from the inlet to the outlet, ensuring that the fluid flowing into the platform does not flow back, thus providing safety and protection.

[0037] Preferably, the pump set includes an electric motor-hydraulic pump set and a pneumatically driven hydraulic pump 53, wherein the hydraulic pump in the electric motor-hydraulic pump set is a plunger pump. The pump set consists of an electric motor-hydraulic pump set and a pneumatically driven hydraulic pump 53. The electric motor-hydraulic pump set is a plunger pump, with the pump head made of 316 stainless steel. Its output flow rate is greater than 10 L / min, and its maximum output pressure is greater than 2000 psi. When the pressure inside the test body reaches 2000 psi, it automatically switches to the pneumatically driven hydraulic pump 53, which has a maximum output pressure greater than 25000 psi and a displacement greater than 10 ml / stroke. The pneumatically driven hydraulic pump 53 is driven by compressed air, with a working air pressure of 0.6~0.8 MPa, thus meeting high-pressure testing requirements and providing versatility and switchability.

[0038] The platform's design, manufacturing, installation, and testing adhere to API RP 14A / 14B / 14C standards, while hydraulic piping conforms to ANSI / API RP 574-2009, API 1104, and GB 50236-2011 standards. Through integrated design, it achieves a balance between portability, a wide pressure range, high automation, and high safety, fully complying with API, HG, and other industry standards. It can be widely used for hydraulic testing of subsea wellhead assemblies, effectively improving testing efficiency and reliability, demonstrating significant practical value and promising prospects for wider application, thus offering both convenience and reliability.

[0039] The implementation principle of a mobile hydraulic testing platform is as follows: The platform is moved to the test site and secured to the ground using the casters. Pure water is then added to the water tank 55, and the water level is checked using a level gauge. Next, the device under test is connected to the platform's outlet hose. The test mode is selected via the touchscreen 51, and parameters such as test pressure and holding time are set. The motor-driven water pump unit is started to inject water into the device under test and pressurize it. When the pressure reaches 2000 psi, the system automatically stops the motor-driven pump unit and then starts the pneumatic pump 53 to continue pressurizing to the set pressure. Once the set pressure is reached, the pneumatic pump 53 stops operating. The needle valve will also close, putting the system into a pressure-holding state. This will trigger the timer to start counting down. The pressure transmitter can monitor pressure changes in real time, synchronizing the data to the control software and generating curves. After the pressure-holding time ends, the pneumatic needle valve will automatically open to release pressure, reducing it to a safe range before closing again. Once the platform test is complete, the software will automatically generate a PDF test report containing pressure, time curves, temperature data, etc. The report can also be printed in both Chinese and English for easy viewing and analysis of the test data.

[0040] Based on a mobile hydraulic measurement and control system, this invention ensures the cleanliness of the test medium through a high-precision filtration component, preventing contamination of the tested equipment or affecting the test results. Equipped with safety valves, check valves, and other protective devices, it reduces the risks of system overpressure and backflow. If the pressure drop rate exceeds a set threshold during testing, the system automatically alarms and records the event. A reserved network interface allows for remote data transmission and monitoring, facilitating future functional upgrades.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
