Abstract: Vibration fault is a common fault of rotating equipment in petrochemical plants. From the perspective of field construction, this paper analyzes the types and causes of vibration faults of rotating equipment. Based on waveform and spectrum measurement results, the direct cause of vibration fault can be analyzed and judged scientifically during construction. And corresponding measures such as cladding welding repair process, bearing bush assembly process, laser alignment equipment, locking bolt, and internal seal installation methods and so on can be adopted to prevent and eliminate vibration faults, thus achieving a vibration fault rate of less than 0.5% during the general equipment maintenance cycle.

Key words: petrochemical plant, rotating equipment, vibration, fault
