Similarly, Zhejiang Xiangyu Sealing Parts Co., Ltd.'s Chinese patent application number 202210502003.X discloses a performance testing machine for long-life subway axle box bearing seals, mainly applicable to the compressive and tensile testing of bearing seals. Anhui Jinli Pump Industry Technology Co., Ltd.'s patent application number 2022110308... Chinese patent 13.6 discloses a sealing detection device for cooling water pump bearings, which is mainly used to accurately locate leakage points. For example, Chinese patent application number 202210936104.8 of Anhui Zhongke Duling Commercial Electric Appliance Co., Ltd. discloses a sealed carbon dioxide incubator and its sealing detection equipment, which is mainly used for sealing detection of incubation chambers. For example, Chinese patent application number 202210844417.0 of Shenzhen Xinkeying Technology Co., Ltd. discloses a waterproof sealing detection device for smartwatches, which is mainly for testing the waterproofness of smartwatches.

[0044] In use, the sealing ring to be tested is placed in the receiving groove, and according to actual needs, the corresponding gas or liquid is filled into the sealing tank 21 through the gas sealing detection device 3 and the liquid sealing detection device 4, thereby simulating the corresponding gas environment or liquid environment.

[0045] According to actual needs, the ultrasonic vibration mechanical fatigue test mechanism 22, the clamping force test mechanism 23 and the thermal aging test mechanism 24 are activated. Usually, ultrasonic, vibration and heating are used to simulate fatigue damage and aging, and the sealing performance of the sealing ring under test is detected by the gas sealing test device 3 and the liquid sealing test device 4.

[0046] The test device 2, gas sealing test device 3, and liquid sealing test device 4 of this invention work together to effectively simulate fatigue aging in different liquid and gas environments according to actual needs, through ultrasonic vibration, clamping force, and heating. This allows the sealing test of the sealing ring to reach a realistic environment, resulting in significant testing effects and accurate testing structure.

[0047] Example 2:

[0048] Example 2 is based on Example 1:

[0049] like Figure 4 and Figure 5 As shown, the sealed container 21 includes a double-cavity container body 211 and a container lid 212. The container lid 212 is configured as a barrel structure with an opening at the bottom. The diameter of the opening at the bottom is adapted to the top diameter of the double-cavity container body 211. The container lid 212 can be detachably placed on the top of the double-cavity container body 211.

[0050] The dual-cavity tank 211 has an inner cavity 2112 and an outer cavity 2111 surrounding the inner cavity 2112. A first receiving groove 2113 is provided on the top side of the inner cavity 2112, and the first receiving groove 2113 matches the shape of the sealing ring to be tested. (Refer to...) Figure 11As shown, the cross-sectional shape of the first receiving groove 2113 is set to semi-circular, triangular, rectangular or dovetail, etc. The first receiving groove 2113 is an annular groove, and the number of the first receiving groove 2113 is set to multiple, which are distributed from the inside to the outside on the top side of the inner cavity 2112, suitable for different types and specifications of sealing rings.

[0051] The top side of the outer cavity 2111 is provided with a second receiving groove 2114 for placing a standard sealing ring, which is used to seal the outer cavity 2111 and the can lid 212.

[0052] Both the inner cavity 2112 and the outer cavity 2111 are connected to the gas seal detection device 3;

[0053] Both the inner cavity 2112 and the outer cavity 2111 are connected to the liquid sealing detection device 4.

[0054] The sealing tank 1 adopts a dual-chamber structure, which can simulate various environments such as internal liquid and external gas, internal liquid and external liquid, internal gas and external gas, and internal gas and external liquid. It can separately test the sealing performance under complex environments such as different gas pressure states inside and outside the sealing ring, different hydraulic pressure states, different gases, and different liquids.

[0055] The sealed container 21 is made of corrosion-resistant and insulating material, and its design pressure is 1.5 MPa. To improve the safety of the sealed container 21, an inner and outer cavity pressure relief safety valve is installed on the sealed container 21, and a protective cover 13 is installed on the outside of the sealed container 21.

[0056] like Figure 1 and Figure 3 As shown, the support device 1 includes a test bench 11, which includes a frame and a table surface located on the top side of the frame. The table surface is provided with a receiving hole that matches the size of the double-cavity tank 211. A support surface is provided inside the frame at the position corresponding to the receiving hole. The bottom of the double-cavity tank 211 passes through the receiving hole and is placed on the support surface. A protective cover 13 is provided on the table surface and covers the sealed tank 21.

[0057] like Figure 7 As shown, the bottom edge of the protective cover 13 is connected to the connecting block of the flip handle 131. The connecting block is connected to the test bench 11 via the hinge 14. By holding the flip handle 131 and rotating it, the protective cover 13 can be flipped, thereby exposing the sealed container 21.

[0058] As an optional implementation, such as Figure 3 and Figure 8 As shown, the test bench 11 is provided with casters 15 on its bottom side, making the test bench 11 a movable test bench that is easy to move.

[0059] The test bench 11 is equipped with feet 16 on its bottom side. The feet 16 are adjustable feet. When the test bench is moved to the designated position, the feet 16 are adjusted to make them contact the ground and place the bench stably.

[0060] As an optional implementation, such as Figure 3 and Figure 6 As shown, the test device 2 includes a can lid opening and closing mechanism 25, which includes a can lid lifting mechanism 251 and a can lid extraction mechanism 252. The can lid lifting mechanism 251 is connected to the can lid 212 through the can lid extraction mechanism 252 and is used to open and close the can lid 212.

[0061] The can lid lifting mechanism 251 includes a vertical guide assembly 2512 and a telescopic lifting assembly 2511. The vertical guide assembly 2512 includes a vertical guide rail 25121 mounted on the support device 1 and a slider assembly slidably mounted on the vertical guide rail 25121. The slider assembly is connected to the telescopic lifting assembly 2511. Optionally, the telescopic lifting assembly 2511 can be an electric telescopic mechanism, a pneumatic telescopic mechanism, or a hydraulic telescopic mechanism.

[0062] The support device 1 includes a mounting frame 12, which includes two vertically mounted columns 121 and a horizontally mounted crossbeam 122 on top of the two columns 121. A vertical fixing plate 123 is mounted on the crossbeam 122, and a vertical guide rail 25121 is mounted on the vertical fixing plate 123. A mounting plate is mounted on the top of the vertical fixing plate 123, and a telescopic lifting assembly 2511 is mounted on the mounting plate.

[0063] like Figure 9 As shown, the vertical guide assembly 2512 includes a slider 25122 and a slider connecting plate 25123 connected to the slider 25122. The slider 25122 is slidably disposed on the vertical guide rail 25121.

[0064] like Figure 12 As shown, the telescopic lifting assembly 2511 is configured as an electric telescopic mechanism, which includes a stepper motor 25111 and a reducer 25112 connected to the stepper motor 25111. A drive screw is connected to the output end of the reducer 25112. A lifting nut is sleeved on the outside of the drive screw. The lifting nut is fixedly mounted on the slider connecting plate 25123.

[0065] During the opening or closing of the can lid 212, the stepper motor 25111 starts, the drive screw rotates, and under the guidance of the vertical guide rail 25121, the slider assembly rises and falls synchronously with the nut, thereby driving the can lid extraction mechanism 252 to rise and fall.

[0066] It adopts an electric telescopic mechanism, which has the advantages of stable lifting process, high running accuracy, large load, and no noise during operation.

[0067] like Figure 10 As shown, the can lid extraction mechanism 252 includes a connecting bracket 2521 and a suction cup 2522. The number of suction cups 2522 is set to multiple, and all suction cups 2522 are evenly arranged on the connecting bracket 2521 in the circumferential direction.

[0068] The connecting bracket 2521 includes three circumferentially evenly distributed connecting rods, and the number of suction cups 2522 is set to three. The suction cups 2522 are set on the corresponding connecting rods, and the can lid extraction mechanism 252 is set as a three-claw stabilizer.

[0069] During the opening or closing of the can lid 212, the telescopic lifting component 2511 can drive the connecting bracket 2521 to rise or fall, thereby causing the suction cup 2522 to pick up and drive the can lid 212 to rise or fall.

[0070] As an optional implementation, such as Figure 6 As shown, the ultrasonic vibration mechanical fatigue testing mechanism 22 includes an ultrasonic generator 221 and a transducer 222.

[0071] An ultrasonic generator 221 is mounted on the stand and located below the stand surface. The ultrasonic generator 221 is connected to the transducer 222 via a wire.

[0072] The oscillator transducer 222 is connected to the slider connecting plate 25123 with the lifting nut, and the connecting bracket 2521 is connected to the bottom side of the oscillator transducer 222.

[0073] In actual use, the ultrasonic generator 221 and the transducer 222 work together to generate ultrasonic vibration, which can effectively simulate the sealing performance of the sealing ring under mechanical fatigue.

[0074] As an optional implementation, such as Figure 6 and 11 As shown, the clamping force testing mechanism 23 includes a hydraulic component 231 and a pressure sensing pad, and the hydraulic component 231 is configured as a hydraulic actuator.

[0075] One end of the hydraulic component 231 is connected to the connecting bracket 2521, and the other end of the hydraulic component 231 is attached to the top of the tank cover 212 through the pressure sensing pad.

[0076] The hydraulic component 231 and the pressure sensing pad work together to apply a specified pressure to the can lid 212 according to actual needs, thereby applying pressure to the sealing ring to be tested, which can effectively simulate the sealing performance of the sealing ring under different clamping forces.

[0077] As an optional implementation, such as Figure 5 and Figure 6As shown, the thermal aging test mechanism 24 includes a heating tube 241 and a heating temperature controller 242.

[0078] The heating element 241 is located inside the can lid 212, and the heating temperature controller 242 is located on the top of the can lid 212. The heating temperature controller 242 is electrically connected to the heating element 241.

[0079] During the sealing test, the heating tube 241 is controlled by the heating temperature controller 242 to heat to the specified temperature, which can effectively simulate the sealing performance of the sealing ring after thermal aging.

[0080] As an optional implementation, such as Figure 13 As shown, the gas sealing test device 3 includes an inner cavity air inlet pipe 31, which is set on the frame of the test bench 11 and located below its surface. The inner cavity air inlet pipe 31 includes a first air inlet pipe 311 and a second air inlet pipe 312 arranged in parallel.

[0081] The first air intake pipe 311 is connected to the inner cavity 2112. A one-way valve 32 and a pressure gauge 33 are installed on the first air intake pipe 311. The second air intake pipe 312 is connected to the inner cavity 2112. A flow monitor 34 and a one-way valve 32 are installed on the second air intake pipe 312. An internal exhaust port is provided on the dual-cavity tank 211, which is connected to the inner cavity 2112.

[0082] The gas seal testing device 3 includes an external cavity air inlet pipe 35, which is set on the frame of the test bench 11 and located below its surface. The external cavity air inlet pipe 35 is connected to the external cavity body 2111. A barometer 36 and a one-way valve 32 are installed on the external cavity air inlet pipe 35. An external exhaust port is provided on the dual-cavity tank 211, which is connected to the external cavity body 2111.

[0083] The gas seal detection device 3 includes a gas seal leakage detection device, which is installed on the upper side of the test bench 11 and is configured as an inert gas leakage detection lamp 37.

[0084] During the airtightness test of the sealing ring, after injecting gas into the dual-chamber tank 211, the first air inlet pipe 311 is closed. When gas leaks, the pressure drops, and gas is supplied through the second air inlet pipe 312 to maintain a stable pressure. During this process, the flow monitor 34 can effectively record the gas leakage rate, and the inert gas leakage detection light 37 can also intuitively reflect the sealing performance of the sealing ring.

[0085] As an optional implementation, such as Figure 14As shown, the liquid sealing test device 4 includes an inner cavity liquid inlet pipe 41, which is located on the upper side of the test bench 11. The inner cavity liquid inlet pipe 41 is connected to the inner cavity body 2112. A three-way connector 42 is provided on the inner cavity liquid inlet pipe 41. A liquid sealing test mechanism 43 is connected to the upper connector of the three-way connector 42. An inner liquid outlet is provided on the double cavity tank 211, which is connected to the inner cavity body 2112.

[0086] The liquid sealing test device 4 includes an external cavity liquid inlet pipe 44, which is located on the upper side of the test bench 11. A hydraulic gauge 45 is installed on the external cavity liquid inlet pipe 44, and an external liquid outlet is provided on the dual-cavity tank 211, which is connected to the external cavity 2111.

[0087] like Figure 15 and Figure 16 As shown, the liquid seal detection mechanism 43 adopts a mechanical detection mechanism, which includes a support frame 431, a piston connecting rod 432, a buffer 433, an indicator light 434, and a power supply. The buffer 433 is set as a spring.

[0088] The support frame 431 has a piston chamber 4311 inside. The piston end of the piston rod 432 is slidably inserted into the piston chamber 4311. The piston end of the piston rod 432 is provided with a first conductive plate 435. The support frame 431 is provided with an upper limit seat 437. The connecting rod end of the piston rod 432 is provided with a lower limit seat 438. The buffer 433 is sleeved on the outside of the piston rod 432, and its two ends abut against the upper limit seat 437 and the lower limit seat 438 respectively. The connecting rod end of the piston rod 432 is connected to a hydraulic push tube 439. The hydraulic push tube 439 has a hydraulic push cavity 4391 inside. The end of the hydraulic push tube 439 is connected to the hydraulic push cavity 4391 and is provided with a liquid inlet. The liquid inlet is connected to the upper connector of the three-way connector 42.

[0089] An adjustment knob 4371 is provided on the upper limit seat 437. Rotating the adjustment knob 4371 can adjust the elasticity of the buffer 433.

[0090] The support frame 431 has an installation cavity 4312 inside. The power supply is located in the installation cavity 4312 and is electrically connected to the indicator light 434. The indicator light 434 is electrically connected to a second conductive sheet 436.

[0091] During the liquid tightness test of the sealing ring, liquid enters the liquid ejection chamber 4391 through the inlet. When the pressure is reached, the liquid pressure overcomes the elastic force of the buffer 433 and pushes the liquid ejection tube 439 and piston rod 432 to rise synchronously. The first conductive plate 435 and the second conductive plate 436 touch, and the indicator light 434 lights up. When the sealing ring leaks, the hydraulic pressure decreases. Under the elastic force of the buffer 433, the first conductive plate 435 and the second conductive plate 436 separate, and the indicator light 434 goes out.

[0092] The gas sealing detection device 3 and liquid sealing detection device 4 of the present invention can not only detect the sealing effect of the sealing ring under different environments, but also make accurate and visual judgments.

[0093] As an optional implementation, such as 1- Figure 3 As shown, the sealing test device that can simulate various complex environments includes an electrical integrated control device 5, which includes an electrical control box 51. The electrical control box 51 is set on the test bench 11. The test device 2, the gas sealing test device 3, and the liquid sealing test device 4 are all electrically connected to the electrical control box 51.

[0094] The electrical control box 51 is equipped with a human-machine interface screen. During actual use, the gas seal detection device 3 and the liquid seal detection device 4 feed back their information to the electrical control box 51. The ultrasonic vibration mechanical fatigue testing mechanism 22, the clamping force testing mechanism 23, and the thermal aging testing mechanism 24 feed back their mechanical vibration information, clamping force information, and temperature information to the electrical control box 51. The human-machine interface screen can intuitively display the information of each device, and users can directly control each device by touching the screen.

[0095] The inclusion of the electrical integrated control device 5 makes the sealing detection device, which can simulate various complex environments, more intelligent.
