Description

Technical Field

[0001] This utility model relates to the field of rotary joint technology, and more specifically, to an automated testing box for high-speed rotary joints. Background Technology

[0002] High-speed rotary joints utilize dynamic sealing technology to maintain the continuous flow of liquids or gases while rotating at high speeds. Their core lies in the use of sealing rings made of special materials. These rings fit tightly against the inside of the joint during high-speed rotation, forming a sealing barrier to ensure no fluid leakage. Furthermore, they typically employ a multi-layer sealing structure, with each layer of sealing rings serving a different function, such as preventing fluid leakage, withstanding centrifugal force, and dissipating heat, working together to ensure the stability of the joint during high-speed rotation.

[0003] Currently, high-speed rotary joints maintain the continuous flow of liquids or gases while rotating at high speeds. After reaching their service life, the internal seals of high-speed rotary joints are prone to wear, leading to air leakage. If the set time is not reached, the equipment continues to run, making it impossible to accurately determine the actual service life of the product. Therefore, this utility model proposes an automated testing box for high-speed rotary joints. Utility Model Content

[0029] Example:

[0030] Please see Figure 1-3 An automated testing box for high-speed rotary joints includes a chassis 1. Multiple sets of bearing seats 3 are fixedly connected to the top of the chassis 1. Hollow tubes 4 are rotatably connected within each set of bearing seats 3. Rotary joint bodies 5 are rotatably connected to both ends of each hollow tube 4. The rotary joint bodies 5 are symmetrically distributed on both sides of the bearing seats 3 and communicate with the hollow tubes 4. An air intake pressure valve 6 is fixedly connected to one side of the chassis 1 and communicates with the rotary joint bodies 5 on one side of the bearing seats 3 via a pipe. Multiple solenoid valves 7 are fixedly connected to the top of the chassis 1 and communicate with the rotary joint bodies 5 on the other side of the bearing seats 3 via pipes. A monitoring module 8 is fixedly connected to the chassis 1 and communicates with the rotary joint bodies 5 via pipes. A linkage mechanism is provided between the chassis 1 and the hollow tubes 4 to control the rotation of the hollow tubes 4.

[0031] In this embodiment, during the high-speed rotary joint test, multiple rotary joint bodies 5 are rotatably connected to both ends of multiple hollow tubes 4. One end of each hollow tube 4 is connected to an intake pressure valve 6 via a pipe, while the other end is connected to multiple solenoid valves 7 via pipes. These pipes secure the rotary joint bodies 5 to the chassis 1. A monitoring module 8 is connected via pipes to the junctions of the solenoid valves 7, the intake pressure valve 6, and the rotary joint bodies 5. A linkage mechanism controls the rotation of the hollow tubes 4 within multiple sets of bearing seats 3. The intake pressure valve 6 draws air into the rotary joint bodies 5 and the hollow tubes 4, and finally discharges it through the solenoid valves 7, creating a gas flow. The monitoring module 8 adjusts and monitors the pressure of the flowing gas drawn by the intake pressure valve 6 and monitors the gas about to be discharged from the solenoid valves 7. By comparing the gas pressure drawn by the intake pressure valve 6 with the gas pressure about to be discharged from the solenoid valves 7, the service life of the multiple rotary joint bodies 5 is determined.

[0032] Specifically, the monitoring module 8 includes multiple digital pressure modules 81 and pressure regulating valves 82. The multiple digital pressure modules 81 and pressure regulating valves 82 are all fixedly connected to the chassis 1. The multiple digital pressure modules 81 are connected to multiple rotary joint bodies 5 through pipes, and the pressure regulating valves 82 are connected to the intake pressure valves 6 through pipes.

Multiple digital pressure modules 81 are connected between the intake pressure valve 6, the solenoid valves 7 and the multiple rotary joint bodies 5 via pipes, respectively monitoring and comparing the gas pressure drawn by the intake pressure valve 6 and the gas pressure about to be discharged by the multiple solenoid valves 7. The pressure regulating valve 82 is used to control the pressure of the air drawn by the intake pressure valve 6.

[0034] Specifically, the linkage mechanism includes a stepper motor 91, a synchronous pulley assembly 92, and a synchronous belt assembly 93. The stepper motor 91 is fixedly connected inside the housing 1. The synchronous pulley assembly 92 is fixedly connected to the output end of the stepper motor 91 and the circumferential surface of multiple hollow tubes 4. The synchronous belt assembly 93 is drivenly connected to the synchronous pulley assembly 92.

[0035] In this embodiment, the output end of the stepper motor 91 rotates, causing the synchronous pulley assembly 92 to rotate synchronously through the synchronous belt assembly 93, thereby driving multiple hollow tubes 4 in multiple sets of bearing seats 3 to rotate simultaneously, and testing the service life of multiple rotary joint bodies 5.

[0036] Specifically, each set of bearing housings 3 is set to two, and each hollow tube 4 passes through a set of two bearing housings 3.

[0037] In this embodiment, each set of two bearing seats 3 supports the rotation of a hollow tube 4, so that the rotation of multiple hollow tubes 4 remains stable.

[0038] Specifically, the timing pulley assembly 92 and the timing belt assembly 93 are located inside the multiple sets of bearing housings 3.

[0039] In this embodiment, the synchronous pulley assembly 92 and the synchronous belt assembly 93 drive multiple hollow tubes 4 to rotate inside multiple sets of bearing seats 3, so that the multiple hollow tubes 4 are subjected to uniform force and remain stable during rotation.

[0040] Specifically, a sensor 10 is fixedly connected to the top of the chassis 1, and the sensor 10 corresponds to a hollow tube 4.

[0041] In this embodiment, sensor 10 corresponds to one hollow tube 4. Multiple hollow tubes 4 rotate synchronously. Sensor 10 can sense the number of rotations of multiple hollow tubes 4 and determine the service life of multiple rotary joint bodies 5 based on the number of rotations.

[0042] Specifically, a power supply control box 2 is provided on one side of the chassis 1, and the intake pressure valve 6, multiple solenoid valves 7, multiple digital pressure modules 81, pressure regulating valve 82, stepper motor 91 and sensor 10 are all electrically connected to the power supply control box 2.

[0043] In this embodiment, the power supply control box 2 is connected to an external power source to supply power and control the intake pressure valve 6, multiple solenoid valves 7, multiple digital pressure modules 81, pressure regulating valve 82, stepper motor 91 and sensor 10.

[0044] Specifically, a control panel 12 is fixedly connected to one side of the power supply control box 2, and the control panel 12 is electrically connected to the power supply control box 2.

[0045] In this embodiment, the staff operates the test box through the control panel 12 to test multiple rotary joint bodies 5.

[0046] Specifically, heat dissipation hole groups 13 are provided on both symmetrical ends of the power supply control box 2, and the two heat dissipation hole groups 13 are connected to the power supply control box 2.

[0047] In this embodiment, two heat dissipation hole groups 13 are used to dissipate heat from the power supply control box 2, thereby improving the service life of the power supply control box 2.

[0048] Specifically, handles 11 are fixedly connected to both symmetrical ends of the chassis 1, and the same handles 11 are fixedly connected to the top of the power supply control box 2.

[0049] In this embodiment, three handles 11 provide handholds for the staff, facilitating the movement of the chassis 1 and the power supply control box 2.

[0050] Working principle: During high-speed rotary joint testing, multiple rotary joint bodies 5 are rotatably connected to both ends of multiple hollow tubes 4. One end of each hollow tube 4 is connected to an intake pressure valve 6 via a pipe, while the other end is connected to multiple solenoid valves 7 via pipes. These pipes secure the rotary joint bodies 5 to the housing 1. A monitoring module 8 is connected via pipes to the junctions of the solenoid valves 7 and intake pressure valves 6 with the rotary joint bodies 5. The stepper motor 91 rotates, causing the synchronous pulley assembly 92 to rotate via the synchronous belt assembly 93. The synchronous rotation drives multiple hollow tubes 4 within multiple bearing housings 3 to rotate simultaneously. The intake pressure valve 6 draws air into multiple rotary joint bodies 5 and multiple hollow tubes 4, and finally discharges it through multiple solenoid valves 7 connected by pipelines, causing the gas to flow. The monitoring module 8 adjusts and monitors the pressure of the flowing gas drawn by the intake pressure valve 6 and monitors the gas about to be discharged by the multiple solenoid valves 7. By comparing the gas pressure drawn by the intake pressure valve 6 with the gas pressure about to be discharged by the multiple solenoid valves 7, the service life of the multiple rotary joint bodies 5 under the rotating state is determined.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
