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, ...

Why is it necessary to repair high-pressure fan impeller shafts? The high-pressure fan shaft is a critical component in industrial fan systems, often installed in positions such as air supply fans, dust extraction fans, drying fans, and gas recirculation fans. These shafts are widely used in various mechanical engineering industries, ...

The rotor is a critical component of the Roots blower – a device commonly used in air supply systems for wastewater treatment plants, aquaculture facilities, food processing, cement production, textile, and dyeing industries. After prolonged operation, the shaft journals of the rotor often experience wear, scratches, or dimensional loss, directly ...

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 ...

Repairing small bores such as Ø70 is one of the most technically demanding challenges in precision mechanical restoration. With a narrow diameter and limited space, the process requires extremely high accuracy, along with precise control of the heat input and cladding thickness to ensure strong bonding and coating quality. Challenges ...

Laser Cladding is an advanced surface restoration and strengthening technology. It utilizes a high-energy, focused laser beam to melt metallic powder and fuse it with the base material surface. This process creates a dense, wear-resistant coating with excellent bonding and mechanical properties. Laser cladding is especially suitable for components subject ...
