Why Choose Advanced Vacuum Pressure Impregnation (VPI) Equipment?
In the fields of new energy, wind power, and rail transit, VPI equipment is the core guarantee for the long-term reliable operation of devices.
Solving Pain Points: Completely eliminates issues inherent in traditional varnishing processes, such as residual air bubbles, low fill rates, and uneven insulation.
Core Value: Through the dual action of "high-vacuum degassing + high-pressure impregnation," it achieves 100% resin penetration into micro-pores, creating a perfect, air-gap-free, high-density insulation layer that prevents partial discharge and overheating failures.
I. Four Core Technical Advantages
1. Ultimate Vacuum and Precision Pressurization
Ultra-High Vacuum: Utilizes multi-stage Roots pump sets combined with dry vacuum pumps to achieve an ultimate vacuum degree of <5Pa, thoroughly removing moisture and volatiles.
Precision Pressurization: With a pressure rating of 0.9MPa and high-response proportional valves, it ensures damage-free resin penetration, achieving a fill rate of >98%.
2. Intelligent Temperature Control and Resin Management
Constant Temperature Control: Features independent PID multi-zone heating with temperature variance controlled within ±1°C, preventing premature resin gelation or viscosity fluctuations.
Automatic Circulation: Equipped with built-in high-precision filtration and stirring systems that monitor viscosity in real-time, ensuring batch-to-batch consistency.
3. Industry 4.0 Full-Process Automation
One-Touch Operation: Pre-loaded with various recipes (for flat wire/Hair-pin, round wire, and high-voltage applications), the system automatically completes the sequence: Preheating → Vacuum → Impregnation → Pressurization → Dripping → Cleaning.
Data Traceability: Records all parameters (vacuum, pressure, temperature, time) in real-time to generate tamper-proof reports, meeting ISO/UL/TUV audit requirements.
4. Green Safety and Energy Efficiency
Environmental Compliance: Fully enclosed operation combined with high-efficiency condensation recovery ensures easy compliance with EU CE standards and domestic environmental assessments.
Energy Efficiency: Incorporates variable frequency drives (VFD) and waste heat recovery, reducing comprehensive energy consumption by over 20%.
II. Application Fields: Empowering the Upgrade of High-End Manufacturing Industries
New Energy Vehicles: Specifically designed for Hair-pin (flat wire) and high-power density motors; solves high-frequency partial discharge issues and enhances corona resistance.
Wind Power Generation: Adapts to the processing of giant stators, ensuring long-term insulation reliability in harsh marine environments.
Rail Transit: Meets the stringent standards for high heat resistance (Class H/C), vibration resistance, and impact resistance required for high-speed rail and subway motors.
Power Transmission: Enhances the mechanical strength and moisture resistance of high-voltage transformer and reactor coils, preventing loosening and short circuits.
Special Aviation: Provides extreme lightweight and high-reliability insulation solutions for servo and spindle motors.
