AI Technical Summary
During the high-speed rotation detection process of the infrared heat source sensing component, high-pressure inert gas is prone to leakage at the interface between the gas filling joint and the rotor air hole, resulting in poor air cooling effect.
A sealing assembly including a sealing ring, a first sealing ring, a fixing ring, and a second sealing ring is designed. Through the cooperation of these components, leakage of high-pressure inert gas at the gas delivery pipe and the gas port interface is prevented, ensuring that the gas can be effectively blown to the sensing component.
It effectively prevents the leakage of high-pressure inert gas, ensures the air-cooling effect on the sensing components, and improves the reliability of the gas and the cooling effect.
