Comment ça marche
The system employs an above-ground hydraulic turning mechanism driven by a 55KW power unit activating multiple synchronized hydraulic cylinders.
After precise stacking on the 3500×4300mm stacking table, the core is quickly secured to the turning platform (≤20 minutes) via worm gear lifts.
The platform completes 0-90° turning at ≤10min/cycle, with real-time pressure monitoring by the hydraulic system.
Explosion-proof valves and accumulators ensure safety locking in emergencies, while Siemens S7 PLC enables intelligent control of three operational modes through touch screen interface.
Les défis
Transformer manufacturing faces severe challenges in core handling:
- Extreme safety risks in turning 50-ton ultra-heavy cores using traditional methods
- Critical flatness (≤3mm) and vertical accuracy (±0.5°) requirements for silicon steel stacking
- Absolute prohibition of instability, overspeed, or vibration during turning
- Extreme reliability requirements with 30-year service life expectations
- Need for flexible operation across multiple modes (production, maintenance, debugging)
Solutions
- Ultra-heavy Precision Control: Multi-cylinder synchronization ensures smooth 50-ton turning with ±0.5° accuracy
- Dual Safety Protection: Explosion-proof valves + accumulators + mechanical locking provide triple safety assurance
- Intelligent Control: Siemens S7 PLC supports three operational modes for all scenarios
- Long-term Reliability: FEA analysis on critical components and 30-year design life
- Quick Tooling Change: Worm gear tightening enables 20-minute fast securing
- Comprehensive Monitoring: Touch screen displays real-time pressure and fault information for predictive maintenance
