AI Technical Summary
During gas turbine operation, abnormal noise and vibration occur due to the detachment of polyimide wear-resistant tape in the fit clearance between the air pipe and the compressor rotor hub. Existing replacement methods are complex and it is difficult to guarantee the appropriate thickness, which affects the operation of the gas turbine.
The adhesive tape is melted and extruded at 85℃-95℃ to form an adhesive film. The new polyimide wear-resistant tape is then bonded to the end of the air pipe. The thickness of the adhesive film is controlled to be below 0.12mm. Replacement is completed by air cooling molding.
It enables rapid replacement of polyimide wear-resistant belts, ensures appropriate clearance between air pipes and compressor rotor hubs, ensures normal operation of gas turbine, simplifies replacement process and improves efficiency.
