AI Technical Summary

Technical Problem

In marine environments, existing rotating equipment experiences increased clearances due to corrosion, leading to excessive vibrations that affect equipment reliability and operational safety. Existing solutions are either costly or have complex processes and are difficult to meet the requirements for long-term service.

Method used

The positioning ring and outer ring are made of 316L stainless steel. By setting an annular groove and positioning ring between the bearing bracket and the outer pipe, the fitting clearance is reduced, and the connection is made by screws and welding to form a stable structure and improve the stability of the equipment.

Benefits of technology

It effectively reduces the vibration amplitude of rotating equipment, improves the long-term safety and stability of equipment in marine environments, simplifies on-site construction processes, and reduces maintenance costs.
