Operating Conditions and Wear Problems in Pump Shafts Pump shafts operate under high torsional loads and are constantly exposed to friction and corrosive environments. Over time, the shaft surface can become worn, scratched, or pitted—directly affecting concentricity, sealing performance, and the overall lifespan of the pump system. Laser Cladding – ...

Operating Challenges and Wear Problems in Closed Impellers Closed impellers operate under high pressure and high flow velocity, frequently subjected to severe mechanical wear and cavitation—especially along the outer rim and discharge areas… Closed impellers operate under high pressure and high flow velocity, frequently subjected to severe mechanical wear and ...

In industrial stamping press systems, the crankshaft plays a central role — converting the motor’s rotational motion into the up-and-down linear motion of the punch. This enables the press to perform accurate and continuous stamping operations during production. Importance of the Crankshaft The crankshaft endures heavy impact loads, repeating millions ...

Damage Condition During operation, pump casings are exposed to high pressure, friction, and corrosive environments. Critical areas such as bearing seats, flanges, and flow-contact surfaces often suffer from wear, pitting, cracks, or deformation. If not repaired promptly, these damages can cause leakage, reduced efficiency, or even complete pump failure. Laser ...

Restoring pump impellers with metal 3D printing technology (Laser Metal Deposition – LMD, also known as Laser Cladding) is a modern method that rebuilds worn, eroded, or locally corroded parts by adding precise layers of metal material. This technology enables accurate layer-by-layer deposition to restore the original geometry of the ...

Operating conditions of boiler panels In waste-to-energy and biomass power plants, boiler panels operate under extremely harsh environments: Continuous high temperature of 600–800°C. Flue gas containing chlorine and sulfur, causing severe corrosion. Fly ash and solid particles continuously eroding the surface. As a result, panels quickly become thinned, cracked, or ...

What is a Journal Bearing? A journal bearing (also known as a sleeve bearing) is a critical mechanical component used to support and guide rotating shafts in industrial machinery. Over time, the bearing surface is prone to wear, scratches, or cracks due to heavy loads, high rotational speeds, and harsh ...

During operation, bearing housings are often subjected to heavy loads and friction, leading to wear, pitting, cracking, or deformation. These issues reduce service life and negatively impact the overall performance of industrial equipment. At PHUONGDONG INDUSTRY, we apply advanced Laser Cladding technology to restore bearing housings with exceptional precision and ...
