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 ...

In power transmission systems, the coupling is a critical component that connects two shafts and transmits torque. After long periods of operation, the inner surface of the coupling bore often becomes worn, causing vibration and reduced efficiency. At PHUONG DONG, we apply Laser Cladding technology to restore the inner bore ...

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 ...

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 ...

The Importance of the Piston in a Hydraulic Breaker A hydraulic breaker (or hydraulic hammer) is a specialized attachment typically mounted on excavators, used for breaking rocks, concrete, or hard structures. Among its components, the piston plays a crucial role — transmitting the hydraulic energy directly to the chisel tip. ...

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 ...

In industrial pump systems—especially in hydroelectric, thermal power, and oil & gas plants—the impeller plays a vital role in maintaining stable operation and high performance. During long-term use, impellers are exposed to abrasive particles, chemical corrosion, and cavitation, leading to surface wear, pitting, or cracking. These damages reduce pump efficiency, ...

At PHUONG DONG, we are pioneers in applying advanced Laser Cladding technology to restore shafts and other critical machine components using specialized copper alloy powder. This provides an optimal solution for industries such as precision engineering, oil & gas, chemical processing, marine, and many other industrial sectors. Challenges of Copper ...
