Product Uses
1. Thermal Power Plants
Steam turbine rotors are the core component of turbines used in coal-fired and gas-fired power plants. They convert high-pressure steam into rotational energy to drive generators. High thermal resistance and dynamic balance are essential for long-term stable performance.
2. Nuclear Power Auxiliary Systems
In nuclear power stations, steam turbine rotors are used in auxiliary steam systems. These environments demand exceptional corrosion resistance and mechanical reliability. We offer customized materials and precision machining to meet these strict standards.
3. Petrochemical Plants
Steam-driven compressors and pumps in petrochemical facilities rely on turbine rotors for efficient energy transfer. The rotors must endure continuous high-load operation while maintaining fatigue strength and structural stability.
4. Marine Propulsion Systems
Some large vessels, such as LNG carriers, use steam turbines for propulsion. The rotor acts as the central rotating element, requiring reliable power output and excellent thermal stability under harsh marine conditions.
5. Waste Heat Recovery in Industrial Plants
In steel mills, cement factories, and other energy-intensive industries, turbine rotors are used in waste heat recovery systems to convert residual heat into electricity, boosting energy efficiency and reducing emissions.
Product Operate Guide
Before installation, ensure the rotor is clean, free of transport damage, and stored in a dry, vibration-free environment. During assembly, align the rotor precisely with the turbine casing using lifting tools and precision instruments. After installation, conduct a no-load rotation test to verify dynamic balance. Always follow OEM operational procedures and monitor temperature and vibration during operation to ensure long-term safety and performance.
