1. The lower stationary blade bearing cylinder and the matching sealing surface of the lower casing are cambered surfaces, and the lower stationary blade bearing cylinder and the matching sealing surface are required to be glued and sealed during assembly, so that the matching surfaces are stuck and are not easy to separate.
2. The normal phase surface of the lower stationary blade bearing cylinder is matched with the lower casing, the TRT runs for a long time, impurities contained in the gas permeate into the matching surface, so that friction force is increased, and the lower stationary blade bearing cylinder is not easy to take out.
Due to the reasons, a large amount of manpower and material resources are consumed when the stationary blade bearing cylinder is detached each time, so that the overhaul efficiency is seriously affected, and the labor intensity of workers is increased. It is therefore necessary to design a device that allows for easy and quick removal of the vane bearing cylinders.
