AI Technical Summary
Existing technologies cannot effectively remove liquid buildup in gas turbine and aero-engine turbine rotors online, leading to abnormal vibration and structural damage. Furthermore, conventional centrifugal oil removal methods are not applicable, requiring disassembly and cleaning, which is time-consuming and costly.
By operating the turbine rotor in the stable region, monitoring vibration, and utilizing the high-temperature environment to evaporate or coke the accumulated liquid, the accumulated liquid is removed online in conjunction with the drying and coking procedures. This includes determining fault criteria, stable region speed, composition judgment, and corresponding test procedures.
This technology enables online removal of liquid buildup on the turbine rotor, avoiding the time and cost of disassembling the equipment and ensuring its safe and stable operation.
