AI Technical Summary
High-pressure brushless grooving machines generate a lot of dust during operation, which makes it easy for iron filings and dust to be attracted into the air gap between the stator and rotor, leading to problems such as iron rubbing and machine burn-out caused by the stator and rotor.
A dustproof structure was designed, including dustproof inserts, insulating end plates, stator cores, enameled coils, housing, windshields, and O-rings, forming a labyrinth structure to isolate dust and iron filings and prevent them from entering the air gap between the stator and rotor. At the same time, the quick-install and removable cutting blade protective cover facilitates maintenance.
This achieves dust prevention for the high-pressure brushless grooving machine, preventing the stator and rotor from rubbing against the iron and burning out the machine, thus improving the reliability and ease of maintenance of the equipment.
