Vacuum pressure paint dipping device

Abstract

The invention relates to the technical field of paint dipping, and discloses a vacuum pressure paint dipping device. The vacuum pressure paint dipping device comprises a placement groove formed in theground, a steel platform is fixedly connected between the inner walls of the placement groove, a paint dipping tank is fixedly connected to the upper surface of the placement groove through the steelplatform, a first connecting pipe is fixedly connected to the outer surface of the paint dipping tank, two pneumatic ball valves are fixedly connected to the outer surface of the first connecting pipe, a safety valve is fixedly connected to the outer surface of the first connecting pipe, two electric contact vacuum pressure gauges are fixedly connected to the outer surface of the first connectingpipe, and a pneumatic butterfly valve is fixedly connected to the outer surface of the first connecting pipe. The vacuum pressure paint dipping device is used for dipping a dry-type transformer withinsulating paint, a workpiece in the paint dipping tank is vacuumized, the insulating paint is input into the paint dipping tank from a paint storage tank by utilizing the pressure difference betweenthe paint dipping tank and the paint storage tank, and then a certain pressure is applied, so that liquid is fully dipped into a gap in the surface of the workpiece, and the working quality is improved.

Description

technical field [0001] The invention relates to the technical field of paint dipping, in particular to a vacuum pressure paint dipping device. Background technique [0002] Vacuum varnish impregnation is mainly used in the insulation varnish impregnation process of various medium and small transformers, inductors, ballasts, relay contactors, motors, motors, electronic intermediate circuits, frequency regulators and other electronic coils, which can improve the penetration ability of insulating varnish , increase the filling rate, thereby improving the overall mechanical strength, insulation strength and moisture-proof, mildew-proof performance of the electrical coil. It is also suitable for the resin filling of various metal film capacitors, the vacuum degassing process of electrolytic capacitors and small and medium-sized resin crafts, Its advantages are infiltration, filling, degassing uniform, thorough, short time, easy and safe operation, no pollution, and various plasti...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a vacuum pressure varnish impregnating device, which is used for impregnating insulating varnish for dry-type transformers. The pressure difference between them, the insulating varnish is input from the paint storage tank into the immersion tank, and then a certain pressure is applied to make the liquid fully immerse into the gap on the surface of the workpiece, which improves the work quality and solves the problem that if there is a gap on the outer surface of the workpiece, the insulating varnish It is difficult to enter the gap. After the work is completed, there will only be a small amount of insulating paint on the outer surface of the workpiece, resulting in that the outer surface of the workpiece cannot be completely processed, and there are problems of working dead ends and poor working results.
