AI Technical Summary
Existing agitator shaft tubes are prone to cracking under stress concentration, and insufficient sealing allows corrosive substances to enter, affecting reliability and lifespan.
A reinforced fastening ring, sealing ring, and fixing bolt structure are installed on the shaft tube to distribute stress, enhance sealing performance, and enable rapid maintenance through modular design.
It improves the structural rigidity and deformation resistance of the shaft tube, extends fatigue life, reduces friction loss and maintenance costs, is suitable for high-load and corrosive environments, and improves equipment reliability and safety.
