Abstract

The shaft alignment process and maintenance quality of steam turbines are critical to their safe and stable operation. This paper explores the importance of shaft alignment, analyzing potential issues such as vibration amplification, bearing wear, and seal leakage caused by inaccurate alignment. Through innovations in measurement techniques and tool optimization, improved benchmark transfer and adjustment strategies, standardized tool management, standardized operational procedures, thermal expansion considerations, and enhanced personnel skills, the alignment process has been optimized. Additionally, quality control measures such as strengthened personnel management, rigorous process supervision, and stricter acceptance standards are proposed to improve alignment accuracy and maintenance quality, ensuring long-term stable and efficient operation of steam turbines.
