Description

Technical Field

[0001] This invention relates to the field of slip ring testing, and in particular to a single-channel gas-liquid slip ring testing device and method. Background Technology

[0002] A slip ring is a structure that transmits media such as electricity, gas, and liquid during rotation, and includes a rotor end and a stator end, such as... Figure 5 As shown, when testing a single-channel gas-liquid slip ring, because the rotor end needs to be connected to a rotating device, it is impossible to directly introduce a medium to form a test circuit. Currently, a common method is to connect the rotor ends of two single-channel gas-liquid slip rings in series using connecting parts, and use a motor, synchronous belt, and pulleys to achieve rotation. The stator ends serve as the inlet and outlet of the medium, respectively, forming the test circuit. See [link to relevant documentation]. Figure 3 and Figure 4 However, this method has the following drawbacks: the testing equipment is complex and bulky; it is costly, requiring the use of two slip rings and special connectors; and it is difficult to troubleshoot, as it is impossible to directly determine which slip ring is malfunctioning.

[0003] Therefore, there is an urgent need for a simplified method and apparatus that can independently test a single single-channel gas-liquid slip ring. Summary of the Invention

[0004] The purpose of this invention is to provide a single-path gas-liquid slip ring testing device and method, which solves the problems of complex testing equipment, large size, high cost, the need for two slip rings and special connectors, and difficulty in troubleshooting, making it impossible to directly determine which slip ring is malfunctioning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a single-path gas-liquid slip ring testing device, comprising: the stator assembly, a slip ring rotor mounted at the bottom end of the stator assembly, the bottom end of the slip ring rotor mounted on a plug coupling, the plug coupling connected to the output end of a motor, the motor mounted at the bottom of a mounting plate, an aluminum profile connected to the bottom of the mounting plate, and the aluminum profile mounted on a base plate;

[0006] The stator assembly includes a slip ring stator that docks with the slip ring rotor. The top of the slip ring stator has a medium inlet that connects to the medium flow channel inside the slip ring stator. The side end of the slip ring stator has a medium return outlet that connects to the medium flow channel inside the slip ring stator. The medium flow channel inside the slip ring stator and the slip ring rotor form a relatively rotatable sealing pair.

[0007] Preferably, the connection end between the slip ring rotor and the slip ring stator is provided with a plug, and when the slip ring rotor and the slip ring stator are connected, the plug is embedded in the bottom outlet of the medium flow channel to seal it.

[0008] Preferably, the medium return outlet is a threaded hole formed in the side wall of the slip ring stator.

[0009] Preferably, after the test is completed, the medium return outlet can be plugged with a plug and then sealed with adhesive.

[0010] A single-channel gas-liquid slip ring testing method using the device described in claim 1 includes the following steps:

[0011] S1: Modified slip ring: The medium return outlet is machined on the side wall of the stator housing of the slip ring to be tested, and the medium return outlet is connected to the medium flow channel inside the slip ring stator;

[0012] S2: Installation and sealing: Connect the slip ring rotor to the slip ring stator to seal the bottom outlet of the medium flow channel, and then install the slip ring rotor on the output end of the motor;

[0013] S3: Constructing the test circuit: The external medium is introduced into the medium inlet. After the test medium reaches the end of the slip ring rotor through the medium flow channel, it is blocked by the plug seal. The test medium flows back and flows out through the medium return outlet.

[0014] S4: Performance determination: The sealing and unobstructed flow of the stator assembly are determined by monitoring the pressure and flow rate of the medium inlet or the outflow status of the medium return outlet.

[0015] Preferably, the S2 installation and sealing includes the following steps: S21: A plug is provided on the mating surface of the slip ring rotor and the slip ring stator. The plug has a sealing element on its edge. When the slip ring rotor and the slip ring stator are mated, the plug is embedded in the bottom outlet of the medium flow channel for sealing.

[0016] S22: After the slip ring rotor and slip ring stator are connected, further, corresponding seals are installed on the edges where the slip ring rotor and slip ring stator are connected to strengthen the seal, and then the slip ring rotor is installed on the output end of the motor.

[0017] Preferably, after the qualified result is determined in step S4, the medium return outlet is plugged and sealed using a plug and sealing material.

[0018] A single-path gas-liquid slip ring testing method includes the following steps:

[0019] 1. Compared with existing technologies, traditional methods require two slip rings, special connecting parts, and complex transmission systems (motor, synchronous pulley, coupling, etc.), which are cumbersome, occupy a large area, and have high manufacturing costs. In contrast, the present invention only requires machining a return outlet on a single slip ring and using a simple sealing part to form a test circuit. The equipment has a simple structure, small size, and significantly reduced cost.

[0020] 2. In traditional dual slip ring series testing, if leakage or abnormal pressure occurs, both slip rings and connecting components need to be checked one by one, which is a tedious and time-consuming process. This invention only tests a single slip ring, and any test abnormality can be directly attributed to the slip ring itself. Fault diagnosis is fast and accurate, greatly improving testing and quality inspection efficiency.

[0021] 3. After the test of this invention is completed, the return outlet can be permanently sealed by plugging and sealing material to restore the original structure and appearance of the slip ring without affecting its normal use. Therefore, this method is applicable to both product inspection before leaving the factory and performance retesting after maintenance, and has a wide range of applications.

[0029] 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, and 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.

[0030] Please see Figure 1 , Figure 2 as well as Figure 6The present invention provides the following technical solution: a single-channel gas-liquid slip ring testing device, comprising: a stator assembly 1, a slip ring rotor 2 mounted at the bottom of the stator assembly 1, the bottom of the slip ring rotor 2 mounted on a plug coupling 3, the plug coupling 3 connected to the output end of a motor 5, the motor 5 mounted at the bottom of a mounting plate 4, an aluminum profile 6 connected to the bottom of the mounting plate 4, and the aluminum profile 6 mounted on a base plate 7;

[0031] The stator assembly 1 includes a slip ring stator 101 that docks with the slip ring rotor 2. The top of the slip ring stator 101 is provided with a medium inlet 103, which is connected to the medium flow channel 104 inside the slip ring stator 101. The side end of the slip ring stator 101 is provided with a medium return outlet 102, which is connected to the medium flow channel 104 inside the slip ring stator 101. The medium flow channel 104 inside the slip ring stator 101 and the slip ring rotor 2 form a relatively rotatable sealed pair. The test medium that enters the medium flow channel 104 from the medium inlet 103 is blocked by the slip ring rotor 2 after flowing through the medium flow channel 104 and flows out from the medium return outlet 102, thereby forming a closed test circuit inside a single slip ring under test.

[0032] A plug is provided at the connection end between the slip ring rotor 2 and the slip ring stator 101. When the slip ring rotor 2 and the slip ring stator 101 are connected, the plug is embedded in the bottom outlet of the medium flow channel 104 to seal it. The medium return outlet 102 is a threaded hole formed in the side wall of the slip ring stator 101. After the medium return outlet 102 is tested, the medium outlet can be blocked with a plug and then sealed with glue to achieve a seal without affecting the appearance and performance of the slip ring.

[0033] A test method for a single-channel gas-liquid slip ring test device

[0034] S1: Modified slip ring: A medium return outlet 102 is machined on the side wall of the outer shell of the slip ring stator 101 to be tested. The medium return outlet 102 is connected to the medium flow channel 104 inside the slip ring stator 101.

[0035] S2: Installation and sealing: Connect the slip ring rotor 2 to the slip ring stator 101 to seal the bottom outlet of the medium flow channel 104, and then install the slip ring rotor 2 on the output end of the motor 5;

[0036] S3: Constructing a test circuit: External medium is introduced into the medium inlet 103. After the test medium reaches the two ends of the slip ring rotor through the medium flow channel 104, it is blocked by the plug seal. The test medium flows back and flows out through the medium return outlet 102.

[0037] S4: Performance judgment: The sealing and unobstructed flow of stator assembly 1 are judged by monitoring the pressure and flow rate of medium inlet 103 or the outflow status of medium return outlet 102.

[0038] The S2 installation and sealing process includes the following steps: S21: A plug is installed on the mating surface of the slip ring rotor 2 and the slip ring stator 101. The edge of the plug is equipped with a sealing element. When the slip ring rotor 2 and the slip ring stator 101 are mated, the plug is embedded in the bottom outlet of the medium flow channel 104 for sealing.

[0039] S22: After the slip ring rotor 2 and slip ring stator 101 are connected, the corresponding seals are installed on the edges of the slip ring rotor 2 and slip ring stator 101 to strengthen the seal, and then the slip ring rotor 2 is installed on the output end of the motor 5.

[0040] After the condition is deemed acceptable in step S4, the medium return outlet 102 is plugged and sealed using plugs and sealing materials.

[0041] This invention forms a test circuit inside a single slip ring by means of "internal return flow and self-contained loop", which completely eliminates the dependence on the double slip ring series structure and has significant advantages such as equipment simplification, cost reduction and easy fault diagnosis.
