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, ...

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 ...

Laser Cladding for Babbitt bearings is an advanced restoration method widely used for sliding bearings in industrial equipment such as turbines, fans, pumps, and engines. Laser Cladding technology uses a high-power laser beam to melt Babbitt alloy powder and create a strong metallurgical bond with the base material, producing a ...

Broken or chipped teeth on large gears due to overload during operation is a common failure in heavy industries such as cement, steel, and mining. At Phuong Dong Industry, we apply Laser Cladding technology to restore damaged gears, offering a cost-effective and sustainable alternative to complete replacement. Outstanding Advantages of ...

Turbine shaft restoration is a critical part of maintenance for hydropower generating units. At Ba Thuoc 1 Hydropower Plant (Thanh Hoa Province, Vietnam, with an installed capacity of ~60MW), the turbine shaft journal experienced severe wear after prolonged operation, posing risks to system performance and stability. To address the issue, ...
