6-46 Workstations | VC Vacuum Continuous Immersion Equipment | Continuous

Product Specification

1. Product Overview

VC series provides continuous insulation treatment for coils. Its secondary-vacuum process reduces varnish loss and improves penetration for high-volume impregnation and drying lines. Workstations 6-46, maximum immersion height 130-350mm, takt time 3-20min, drying temperature 100-150℃. Typical applications include continuous impregnation and drying of motors with center height up to 355mm, small power transformers, ballasts and related electrical coils.

2. Industry Challenges & Root Cause Analysis

Continuous immersion cannot achieve vacuum impregnation:Traditional continuous immersion equipment struggles to achieve vacuum environment in assembly line production – insufficient impregnation penetration for small-size high-volume coils. Root cause: contradiction between continuous conveying and vacuum sealing.

High varnish loss and low utilization:Long dripping time after impregnation and severe varnish waste increase production costs. Root cause: lack of secondary vacuum and drip recovery design.

Uneven drying and high energy consumption:Uneven temperature distribution during continuous drying affects varnish film curing quality. Root cause: irrational hot air circulation design in drying oven.

Difficult matching of production takt and process:Different coil specifications require adjustment of immersion height, takt time and other parameters – cumbersome changeover. Root cause: lack of programmable control and parameter storage functions.

6. FAQ

Q1: How does continuous immersion equipment achieve vacuum impregnation?

A: Secondary vacuum technology achieves vacuum environment through vacuum chamber during continuous conveying – expels air from coil gaps before impregnation. Overcomes the industry pain point that traditional continuous immersion cannot achieve vacuum impregnation – pioneering technology in China with national patent authorization.

Q2: Can the equipment adapt to different coil specifications?

A: Workstations 6-46 optional, maximum immersion height 130-350mm. Immersion height, takt time, drying temperature and other parameters settable and storable via touchscreen – different product specifications recall corresponding recipes – fast changeover.

Q3: How is varnish loss controlled?

A: Secondary vacuum process reduces varnish loss – dripping station after impregnation recovers excess varnish – improves varnish utilization and reduces production costs.

Q4: How is drying temperature uniformity ensured?

A: Drying oven with hot air circulation design ensures temperature uniformity. Drying temperature 100-150℃ adjustable – linked with impregnation process – stable varnish film curing quality.
