[Product Introduction] Tungsten carbide bushes: reliable wear-resistant solution under harsh working conditions

As a key component for protecting the pump shaft, the durability of the shaft sleeve directly affects the stability of equipment operation and maintenance costs. As the core equipment for fluid control, pump valves are widely used in various fields such as mining, chemical industry, energy, metallurgy, etc. However, when faced with abrasive media such as slurry and mud, or strong corrosive fluids such as acid, alkali, and salt, or extreme working conditions such as high temperature and high pressure, conventional stainless steel, quenched steel, and other materials are often powerless, prone to wear, corrosion, deformation, and other problems, leading to decreased pump efficiency, seal leakage, frequent replacement, and increased downtime and maintenance costs.

The performance boundary of materials is becoming a key bottleneck that restricts the reliability and lifespan of pump and valve equipment.

Tungsten carbide bushes have become a reliable choice for adapting to harsh working conditions due to their more stable material properties.

 

NO.01  Working condition challenges in the pump and valve industry

The operating conditions of the equipment are complex and varied, and different application scenarios impose differentiated but equally stringent requirements on materials:

1、Abrasive wear condition:When equipment such as slurry pumps and mud pumps transport media containing solid particles, the surface of the shaft sleeve is subjected to continuous high-frequency erosion and abrasive wear. Ordinary metal materials wear very quickly under such conditions, resulting in frequent maintenance and severe losses due to shutdown of the equipment.

2、Strong corrosion condition：Chemical process pumps, wastewater treatment pumps, and other equipment often come into contact with corrosive media such as acids, alkalis, and salts. Although stainless steel materials have certain corrosion resistance, they are still prone to pitting corrosion, stress corrosion cracking, and other problems in high temperature and high concentration environments;

Although stainless steel materials have certain corrosion resistance, they are still prone to pitting corrosion, stress corrosion cracking, and other problems in high temperature and high concentration environments.

3、High temperature working condition:The working temperature of equipment such as hot oil pumps and high-temperature pumps often reaches 300-400 ° C. After this temperature range, the performance of ordinary steel deteriorates sharply, the hardness decreases, and the deformation intensifies, seriously threatening the safety of equipment operation.

 

NO.02  Technical advantages of hard alloy materials

Common problems with conventional shaft sleeves

1、Rapid wear and tear, increased operating clearance, and decreased pump efficiency;

2、Easy to rust and pitting, causing medium leakage;

3、Performance decreases under high temperature conditions, making it prone to deformation and jamming;

4、Frequent replacement, high labor, spare parts, and downtime costs.
