Embodiment

[0033] Such as Figure 1-7 As shown, a test device for the test of the rotary seal structure includes a data acquisition unit and a test test unit. The test test unit includes a test bench 9, and a refrigerant storage tank 8 and a rotary seal assembly are arranged in the test bench 9. Both pass through the first A pipe connection, the rotary seal assembly adopts 3D printing, including a first assembly 401 and a second assembly 402, the inlet of the first assembly 401 is connected to the refrigerant storage tank 8, the outlet of the second assembly 402 is connected to the atmosphere, and the two pass through Second pipe connection. One of the purposes of the two-stage rotary seal is to measure the leakage. For the specific structure of the two-stage type, see image 3 , the second solenoid valve 602 can adjust the pressure to form a pressure difference on both sides, which is used to simulate the internal pressure drop of the motor in the superconducting motor, and the value o...

Description

technical field [0001] The invention relates to the field of superconducting motors, in particular to a test device and a test method for testing a rotary sealing structure. Background technique [0002] In a superconducting motor, a rotating sealing structure is required to transmit cold helium gas from the static refrigerator integrated device to the rotating rotor. The sealing effect of the rotating sealing structure directly affects the overall performance of the superconducting motor. a key device. For the non-contact rotary seal-labyrinth seal structure commonly used in existing superconducting motors, it is necessary to study the leakage characteristics of its sealing performance. [0003] Patent CN103148998A discloses an experimental device for a rotary seal ring for vehicles. Its technical solution is that it is used to test the performance of the seal ring. It includes: a drive motor, a pump, a filter, an oil tank, an overflow valve, a pressure sensor A, a flow ra...
