Hydropower Industry

Phuong Dong has carried out numerous equipment restoration projects for hydropower plants, including the turbine runner of Alin B2 Hydropower Plant. After a period of operation, the turbine runner developed various types of damage, including wear, chipping, blade deformation, and corrosion. Phuong Dong carried out inspection, machining, and restoration using ...

The turbine runner is a critical component of a hydropower unit, directly exposed to the force of water during operation. After years of service, turbine runner blades can suffer from wear, cavitation, corrosion, and long, deep cracks, affecting the equipment’s durability and operating performance. In this project, Phuong Dong restored ...

After years of operation in a hydropower environment, the blades of a Francis turbine runner are often affected by cavitation erosion and corrosion, leading to material loss, reduced turbine efficiency, and a shorter service life. In this project, PHUONG DONG successfully restored a Francis turbine runner with a diameter of ...

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 ...

In hydropower plants, the turbine runner is a critical component that directly determines the efficiency and operational stability of the entire unit. During operation, it is exposed to high-pressure water containing sand and various impurities, leading to surface wear and cavitation over time. If not repaired in a timely manner, ...

In hydropower plants, the nozzle needle and seat ring are critical components that are continuously exposed to high-pressure water flow and cavitation. Over time, their working surfaces suffer from wear and erosion, directly affecting system efficiency and operational stability. Laser Cladding technology is an effective restoration solution, helping recover dimensions ...

The slip ring is an important component used in generators and rotating electrical equipment. It is responsible for transmitting electrical current between stationary and rotating parts through carbon brushes. During long-term operation, the slip ring surface may suffer from wear, scratches, pitting, or dimensional reduction, which can affect electrical contact ...

The generator rotor is a critical component in industrial power generation systems, typically operating under heavy loads, high rotational speeds, and high-temperature conditions. After long-term operation, the rotor surface and mirror face may suffer from wear, pitting, scratches, or dimensional deviation, which directly affects the stability and service life of ...

Overview of Laser Cladding Services in Vietnam Laser Cladding services in Vietnam are increasingly being adopted by industrial companies for restoring and extending the service life of metal components. Laser Cladding technology allows the formation of high-strength alloy coatings with excellent wear resistance and corrosion resistance, helping equipment operate reliably ...

In industrial manufacturing and equipment maintenance, the bearing bore in compressor housing is a critical position, subjected to heavy loads and requiring high accuracy and concentricity. After long-term operation, this area is often worn oversized, scratched or pitted, causing vibration and quickly leading to damage of the bearing, shaft and the ...
