AI Technical Summary

Technical Problem

In existing magnetic levitation two-stage centrifugal compressors, the magnets may experience thermal decay under high-temperature conditions, leading to a decrease in magnetism and affecting the normal operation of the equipment.

Method used

Heat is dissipated from the inside of the bearing housing using a heat-conducting fluid and heat dissipation components. The heat is effectively dissipated through the circulation of the heat-conducting fluid and the blowing of the cooling fan, preventing heat accumulation in the magnetic rotating block and the supporting magnet.

Benefits of technology

Effectively maintain the temperature of the magnetic rotating block and the supporting magnet within the normal range, prevent thermal decay, and ensure stable operation of the equipment.
