Description

Technical Field

[0001] This utility model belongs to the field of coil impregnation technology, specifically a coil impregnation device. Background Technology

[0002] The motor coil is the most vulnerable component in the motor structure. In order to improve the moisture and corrosion resistance and insulation strength of the motor coil, as well as improve its mechanical strength, thermal conductivity and heat dissipation effect and delay aging, the rewound motor coil must be impregnated with varnish.

[0003] The specific design and structure of coil impregnation devices may vary depending on the manufacturer and application requirements, but generally they include the following key components: multi-layer frame, paint inlet, and vacuum port. The multi-layer frame is arranged in parallel to match the outer ring size of the motor core coil. Several sets of motor core coils are arranged on the frame. Rubber rings are placed between the frames to contact the two motor core coils, serving as protection and isolation. The paint inlet and vacuum port are located at the top of the frame. The paint inlet introduces paint through a paint inlet pipe, directly delivering the paint into the frame. The vacuum port is used to remove air from the frame before impregnation, improving the impregnation effect. The paint outlet is located at the bottom of the frame, and the paint is discharged through an outlet pipe. Used paint flows out from the outlet, realizing the circulation and recycling of the paint liquid.

[0004] Currently, in the operation of existing coil impregnation equipment, the viscosity of the varnish is prone to change due to various factors such as changes in ambient temperature and humidity, evaporation of varnish solvent, and the interaction of the varnish components themselves. The viscosity of the varnish is crucial to the impregnation quality. Inappropriate viscosity will lead to uneven adhesion and inconsistent thickness of the varnish on the coil surface, affecting the insulation performance and other properties of the coil. This results in a large number of products needing to be reworked due to impregnation quality problems, which seriously affects production efficiency. Utility Model Content
