AI Technical Summary

Technical Problem

Existing small motor impregnation equipment suffers from low impregnation efficiency, bubbles affecting the quality of finished products, and traditional exhaust methods are time-consuming, impacting production efficiency.

Method used

A vacuum-mechanical dual pressurization system consisting of a circulating vacuum pump and a pressurization component, combined with a tilting component and a paint flow guiding component, is used to remove air bubbles through vacuum exhaust and mechanical vibration, thereby achieving a vacuum environment inside the dyeing tank. A heating system is also used to establish a uniform temperature field, optimizing the flowability of the paint and the removal of air bubbles.

Benefits of technology

It significantly shortens the impregnation cycle, improves paint adhesion efficiency and finished product quality, enables parallel operation of impregnation and drying, and enhances production efficiency and insulation performance.
