AI Technical Summary

⚠Technical Problem

The existing centrifugal pump shaft sleeve structure has insufficient wear resistance. The plastic outer layer is prone to aging under high wear or high temperature conditions, resulting in a shortened service life and inconvenient replacement, which increases replacement costs.

⚗Method used

The bushing is made of carbon steel with hard chrome plating, combined with ceramic ring reinforcement and sealing ring, and an external bushing structure including a wear-resistant layer and an anti-corrosion layer. The bushing is fixed by threaded connection and lock nut to improve wear resistance and corrosion resistance.

🎯Benefits of technology

It enhances the wear resistance and corrosion resistance of the bushing, extends its service life, and facilitates the replacement of worn parts, thus reducing maintenance costs.
