High Vacuum Pressurizing Impregnation System (VPI) for Superior Motor Insulation

The High Vacuum Pressurizing Impregnating Equipment is an essential vacuum impregnation system for the insulation treatment of high-voltage motors, explosion-proof motors, and transformers. This advanced VPI system significantly enhances the mechanical strength, insulation grade, and resistance to moisture and mold of electrical windings, ensuring long-term reliability and performance. Engineered for robust, continuous operation, this turnkey solution is ideal for demanding industrial applications.

Core System Components and Robust Construction

At the heart of this VPI equipment is a high-performance autoclave (impregnation tank) constructed to stringent pressure vessel standards (GB150-1998, JB/T4709-2000). Key features of the main vessel include:

• Dimensions: Φ1000×800mm (effective height).

• Performance: Handles a working pressure of 0.6 MPa and achieves a high vacuum of 10 Pa (no-load).

• Safety: Equipped with over-pressure alarms, safety interlocks, and a hydraulic opening system for secure and easy operation.

• Efficiency: Features 100mm thick insulation with thermal oil heating, maintaining a precise working temperature up to 60°C.

The complete vacuum pressure impregnation system is supplied with all necessary components for a seamless operation, including a resin storage tank with stirring and heating, a powerful vacuum unit, and a fully automated control system.

Key Equipment Parameters

Advanced Automation and Control Features

This vacuum impregnation system is designed for precision and repeatability. The electrical control system is the nerve center, featuring:

• PLC Control & HMI: A 21-inch industrial computer provides a user-friendly, fully Chinese interface for easy operation and monitoring. The system supports different user levels (Operator/Administrator).

• Data Recording & Traceability: The system automatically records, stores, and prints all process parameters—including vacuum, pressure, and liquid level over time—creating a permanent, traceable record for each batch.

• Safety & Interlocks: Comprehensive mechanical and electrical safety interlock devices prevent overpressure and operator error, ensuring complete operational safety during the vacuum impregnation process.

Comprehensive Service and Support

We ensure a smooth integration with professional installation, test-running, and on-site training. The equipment is backed by a 13-month warranty and is supported by a full set of technical documentation, including pressure vessel certificates, manuals, foundation drawings, and electrical diagrams.
