[0026] Please see Figures 1 to 5This application provides a high-pressure, high-speed reciprocating sealing multi-factor coupling test device, which may include: a test main platform 1, a hydraulic pump station 2, and a drive system 3. A bearing seat 101 is movably mounted on the test main platform 1, and the test main platform 1 is used to perform reciprocating sealing test on the sealing test fixture. The hydraulic pump station 2 is located on one side of the test main platform 1 and is used to provide pressure to the sealing test fixture. The drive system 3 is mounted on the test main platform 1 and includes a linear drive mechanism and a rotary drive mechanism. The linear drive mechanism is located at the bottom of the bearing seat 101, and the rotary drive mechanism is located at the top of the bearing seat 101. The sealing test fixture is located at the output end of the rotary drive mechanism.

[0027] In this embodiment, when testing the sealing test fixture, the hydraulic pump station 2 provides pressure to the sealing test fixture, and the test main platform 1 performs a reciprocating sealing assessment test on the sealing test fixture under the drive of the linear drive mechanism. At the same time, the rotary drive mechanism performs a rotary sealing verification on the sealing test fixture, so that the sealing test fixture is more in line with the real scenario when being tested.

[0028] Please see Figure 4 In one possible implementation, the linear drive mechanism may include: a servo electric cylinder 4, a guide rod 5, and a servo geared motor 6, wherein the servo electric cylinder 4 is disposed on one side of the bottom of the bearing housing 101; the guide rod 5 is disposed at one end of the servo electric cylinder 4 and connected to the bearing housing 101; the servo geared motor 6 is disposed at the other end of the servo electric cylinder 4 and connected to the servo electric cylinder 4; the rotary drive mechanism may include: a motor base 7, a servo rotary motor 8, and a reciprocating tension / compression sensor 9, wherein the motor base 7 is fixed to the top of the bearing housing 101; the servo rotary motor 8 is fixed to the motor base 7; the reciprocating tension / compression sensor 9 is disposed at the output end of the servo rotary motor 8 and connected to the end of the sealing test fixture.

[0029] In this embodiment, the linear drive mechanism drives the guide rod 5 to perform linear reciprocating motion via the servo electric cylinder 4. The guide rod 5 drives the bearing housing 101 and its top rotary drive mechanism to reciprocate, thereby realizing the reciprocating sealing test of the sealing test fixture. The servo geared motor 6 is connected to the servo electric cylinder 4 and is used to adjust the movement speed of the servo electric cylinder 4 to meet the requirements of different test conditions. At the same time, the servo rotary motor 8 drives the reciprocating tension-compression sensor 9 to rotate. The reciprocating tension-compression sensor 9 transmits the rotational force to the sealing test fixture, thereby verifying the rotational seal of the sealing test fixture. The reciprocating tension-compression sensor 9 can monitor the force on the sealing test fixture in real time during the rotation process, thereby improving the accuracy and reliability of the test.

[0030] Please see Figure 2 In one possible implementation, the test platform 1 may include: a platform base 102, a platform frame 103, an internal platform 104, multiple external transverse slide rails 105, multiple internal longitudinal slide rails 106, a transverse base plate 107, and two internal transverse slide rails 108. The platform frame 103 is mounted on the platform base 102; the internal platform 104 is mounted on the platform base 102 and located inside the platform frame 103; the multiple external transverse slide rails 105 are all mounted on the top of the platform frame 103; the multiple internal longitudinal slide rails 106 are all mounted on the internal platform 104; the transverse base plate 107 is slidably mounted on the multiple internal longitudinal slide rails 106; the two internal transverse slide rails 108 are mounted on the transverse base plate 107; and the bearing seat 101 is slidably mounted on the two internal transverse slide rails 108.

[0031] Specifically, the platform base 102 makes the entire test platform 1 more stable, while the platform frame 103 and internal platform 104 provide a carrier for connecting other components on the test platform 1. During high-speed reciprocating sealing tests on the sealing test fixture, the bearing housing 101 reciprocates at high speed along the internal transverse slide rail 108, thereby driving the sealing test fixture to reciprocate at high speed. After one sealing test fixture completes its test, the transverse base plate 107 can be moved along the internal longitudinal slide rail 106, thus enabling the change of workstation. The arrangement of these slide rails ensures the smooth high-speed reciprocating movement of the sealing test fixture.

[0032] Please see Figure 2 , Figure 5 In one possible implementation, the test platform 1 may further include: a crossbeam 109, two external longitudinal slide rails 110, a radial electric cylinder 111, a radial tension / compression sensor 112, and a roller 113. The crossbeam 109 is slidably mounted on the external transverse slide rails 105; the two external longitudinal slide rails 110 are mounted on the top of the crossbeam 109; the radial electric cylinder 111 is slidably mounted on the two external longitudinal slide rails 110; the radial tension / compression sensor 112 is mounted on the output end of the radial electric cylinder 111; and the roller 113 is fixed to the radial tension / compression sensor 112.

[0033] In this embodiment, the crossbeam 109 is slidably mounted on the external transverse slide rail 105, allowing it to move laterally along the external transverse slide rail 105. This design increases the flexibility of the test platform 1. Two external longitudinal slide rails 110 are located on the top of the crossbeam 109, providing a path for the radial electric cylinder 111 to move longitudinally. The radial electric cylinder 111 is slidably mounted on the two external longitudinal slide rails 110, allowing it to move longitudinally along the external longitudinal slide rails 110. This design enables the radial electric cylinder 111 to move flexibly. A radial tension / compression sensor 112 is located at the output end of the radial electric cylinder 111 to monitor and record the force applied by the radial electric cylinder 111 to the sealing test fixture. This design improves the accuracy and reliability of the test. A roller 113 is fixed to the radial tension / compression sensor 112. The design of the roller 113 reduces friction and provides radial pressure to the sealing test fixture. By setting the roller 113 to be in direct contact with the sealing test fixture, it helps protect the sealing test fixture from damage. Through the synergistic effect of these components, the main testing platform 1 can achieve multi-dimensional and high-precision testing of the sealing test fixture, thereby improving the efficiency and accuracy of the test.

[0034] Please see Figure 2 In one possible implementation, the test platform 1 may further include a joystick assembly 114, wherein the joystick assembly 114 is disposed on the lower side of the transverse base plate 107, and the joystick assembly 114 can realize the longitudinal movement of the transverse base plate 107.

[0035] Specifically, the rocker assembly 114 allows operators to easily adjust the longitudinal position of the transverse base plate 107 by manually operating it. This design not only increases the operational flexibility of the test platform 1 but also helps improve the convenience and efficiency of the test. When it is necessary to change the sealing test fixture at a workstation, the operator only needs to gently shake the rocker assembly 114 to achieve rapid and precise movement of the transverse base plate 107.

[0036] Please see Figure 2 In one possible implementation, the test platform 1 may further include an external lifting device 115 and a lifting electric cylinder 116, wherein the external lifting device 115 is located on the top of the platform frame 103, and the sealing test fixture is located inside the external lifting device 115; the lifting electric cylinder 116 is located on the top of the external lifting device 115, and the lifting electric cylinder 116 is used to lift the sealing test fixture.

[0037] In this embodiment, by setting an external lifting device 115 and a lifting electric cylinder 116 on the top of the external lifting device 115, the sealing test fixture can be lifted by the lifting electric cylinder 116, making it convenient to replace different sealing test fixtures.

[0038] It should be noted that the end of the sealing test fixture is connected to the reciprocating tension and compression sensor (9), and the entire sealing test fixture is located inside the external lifting device 115.

[0039] Please see Figure 3 In one possible implementation, the hydraulic pump station 2 may include: a pump station housing 201, a pneumatic loading module 202, and a hydraulic loading module 203. The pneumatic loading module 202 is disposed within the pump station housing 201 and is used to provide air pressure for the sealing test fixture. The hydraulic loading module 203 is disposed within the pump station housing 201 and is used to provide hydraulic pressure for the sealing test fixture.

[0040] The pneumatic loading module 202 consists of a pressure regulator, a proportional pressure reducing valve, a pneumatic booster, a pneumatic control valve, and a safety valve; the hydraulic loading module 203 consists of an oil tank, a hydraulic pump, a filter, a solenoid valve, and a proportional relief valve. Both the pneumatic loading module 202 and the hydraulic loading module 203 are connected to the sealing test fixture via pipelines to control the pressure and loading of the sealing test fixture. The pneumatic loading module 202 uses compressed air as a power source and controls the pressure applied to the sealing test fixture by adjusting the air pressure, making it suitable for test scenarios requiring lower pressure or rapid response. The hydraulic loading module 203 uses hydraulic oil as the transmission medium, using high-pressure oil generated by a hydraulic pump to load the sealing test fixture, providing greater pressure and a more stable loading effect, making it suitable for test scenarios requiring high pressure or long-term stable loading. By using the pneumatic loading module 202 and the hydraulic loading module 203 together, various loading requirements for the sealing test fixture under different test conditions can be met.

[0041] Furthermore, in one possible implementation, the test platform 1 is provided with mounting holes for two sets of sealing test fixtures.

[0042] Specifically, by setting two sets of installation holes for sealing test fixtures on the main test platform 1, it is possible to switch between them during the test, which can improve the efficiency of reciprocating sealing multi-factor coupling assessment test.

[0043] Please see Figure 1 In one possible implementation, the high-pressure high-speed reciprocating sealed multi-factor coupling test device may further include: an environmental simulation device 10, wherein the environmental simulation device 10 simulates extremely cold, extremely hot or extremely humid environments through internal circulating airflow.

[0044] In this embodiment, the environmental simulation device 10 can simulate different environmental conditions, such as extremely cold, extremely hot, or extremely humid environments, to test the performance of the sealing test fixture under these extreme conditions. Through internal circulating airflow, the environmental simulation device 10 can precisely control the temperature and humidity within the test area, thereby enabling the evaluation of the sealing test fixture under different environmental conditions. This design allows the test device to more comprehensively evaluate the adaptability and reliability of the sealing test fixture, providing strong support for the practical application of the product.

[0045] Please see Figure 1 In one possible implementation, the high-pressure high-speed reciprocating sealing multi-factor coupling test device may further include: a control system 11, wherein the control system 11 is used to control the reciprocating tension and compression sensor 9.

[0046] Specifically, the control system 11 can precisely control the working state of the reciprocating tension / compression sensor 9 through preset programs or instructions. This precise control capability enables the testing device to conduct more detailed and comprehensive tests on the sealing test fixture, thereby improving the accuracy and reliability of the test. At the same time, the control system 11 can also monitor and record the working state and data of the reciprocating tension / compression sensor 9 in real time, providing strong support for subsequent test analysis and evaluation.
