Beschreibung
Zusammenfassung:A 300MW-level low-stress air turbine comprises a front bearing box, a high-pressure cylinder, a middle bearing box, a low-pressure cylinder and a rear bearing box, the front bearing box, the middle bearing box and the rear bearing box are arranged on a front bearing seat, a middle bearing seat and a rear bearing seat respectively, and a front seat frame, a middle seat frame and a rear seat frame are fixed to a foundation frame of the air turbine through foundation bolts and secondary grouting. The front end of the high-pressure cylinder is connected with the front bearing box through the H-shaped centering beam, the rear end of the high-pressure cylinder is connected with the middle bearing box through the H-shaped centering beam, and the front end of the low-pressure cylinder is connected with the rear bearing box through the H-shaped centering beam. The problem of air turbine resonance can be reduced, the excellent vibration characteristic of a shaft system is guaranteed, and stable operation of an air turb
