AI Technical Summary

Technical Problem

Existing rotor laminations suffer from unstable rotation and poor compressive strength, leading to pump speed fluctuations and lamination fatigue fractures, which affect pump efficiency and service life.

Method used

The design incorporates double-headed bolt connection components and layers of polymer materials, nanomaterials, grain-reinforced layers, and wear-resistant layers, combined with a boss structure, to enhance the stability and compressive strength of the rotor laminations.

Benefits of technology

This achieves stable rotation of the rotor laminations during operation and enhances the durability of its compressive strength, reducing wear and ensuring long-term stable operation of the water pump.
