Research on Seal Detection Technology of Aero-engine Fuel and Lubricating Oil System Based on Acoustic Emission
Through theoretical and experimental research on the principle of direct pressure and acoustic emission,the gas seal detection circuit and qualification criteria are designed.The test verifies that the pressure change is used to qualitatively judge whether the system leaks,and the location of the leak point is determined by ultrasonic detection.The detection results are stable and reliable,and the sensitivity and reliability of aero-engine seal inspection are improved.
