Description

TECHNICAL FIELD

[0001] The utility model relates to the winding stator processing technical field, and specifically relates to a winding stator core vacuum impregnation device. BACKGROUND

[0002] Vacuum impregnation is a process used for the insulation treatment of motor stator windings. It involves the penetration of insulating varnish into the windings under vacuum conditions to improve the insulation performance, voltage resistance, heat resistance, mechanical strength, and corrosion resistance of the motor. This process ensures that the varnish fully penetrates the insulation parts of the motor, forming a dense insulation layer, thereby improving the overall performance and reliability of the motor. Existing manual impregnation barrels are sealed using a relatively thick and heavy top cover after the stator winding is placed inside. Several dozen bolts are used for positioning to adapt to the high negative pressure inside the impregnation barrel after vacuum extraction. The vacuum extraction equipment is then connected to the top cover, and the vacuum extraction process can last up to an hour. The top cover is made of steel and is heavy, requiring a single person to control with a lifting cable. Installing multiple bolts is time-consuming, and after the stator winding is impregnated, it needs to be hung for a long time to drip paint and remove residual paint before drying, which is time-consuming and inefficient for impregnating the stator winding.
