Laser Cladding Phương Đông
The turbine shaft seal ring is a critical component in hydropower generating units. After long-term operation, it is often subject to wear, leading to reduced sealing performance and lower operating efficiency. Instead of replacing the component at a high cost, Laser Cladding provides an efficient solution to restore the original dimensions while significantly improving wear and corrosion resistance, thereby extending the service life of the equipment.
At PHUONG DONG, the restoration process is carried out using advanced Laser Cladding systems. The deposited layer forms a metallurgical bond with the base material, ensuring excellent adhesion, minimal heat-affected zone (HAZ), low distortion, and consistent quality.
Below are actual photos showing the restoration process of turbine shaft seal rings at our facility, from the worn condition through Laser Cladding, machining, and the finished component.
Advantages of Laser Cladding
- Restores dimensions accurately according to engineering drawings.
- Produces a metallurgically bonded coating with high bonding strength.
- Minimizes the heat-affected zone (HAZ) and reduces distortion.
- Improves wear resistance and corrosion resistance.
- Extends the service life of turbine shaft seal rings.
- Significantly reduces maintenance costs compared with replacement.
- Shortens plant shutdown time during maintenance.
Applications in Hydropower Plants
Laser Cladding is widely used to restore and protect critical hydropower components, including:
- Turbine runners
- Turbine shaft seal rings
- Turbine shafts
- Bearing journals and bearing seats
- Guide vanes
- Wear rings
- Upper and lower sealing rings
- Turbine cover seal rings
- Nozzles and retaining rings
- Generator rotors
- Slip rings
- Babbitt bearings, guide bearings, and hydraulic cylinders
- Other components exposed to severe wear and corrosion
