Faults In Conveyor Chain

Conveyor chain is the most common chain in industrial chains. From the line to the food industry, conveyor chain is in everywhere. However the conveyor chain wear is also very common. Because conveyor chain is too tired. If the chain has been worn for long time, that will really direct its working efficiency. In fact, you can arranged the chain in a reverse and continue to use with the slight wear one. As we all known, adding lubricating oil regularly to the conveyor chain can decrease the wear. Above all, conveying chain faults are mainly caused of wear for a long time.

Conveyor chain is often regarded as handling equipment parts in modern industry. With the application of automatic mechanical transmission equipment, conveyor chain is not only limited in mechanical equipment field. Nowadays you can usually see people use conveying chain plate. Such as climbing lift with chain plate. The main structure of conveyor chain material adopts carbon steel or galvanized material. It is made by its surface treatment technology. It could adapt to strong material load and widely used in metal manufacturing industry. That has strong cut resistant and shock resistant ability.

Types of Industrial Chains and How to Maintain

Types of Industrial Chains and How to Maintain

Industrial chains play a crucial role in various industries, including manufacturing, mining, agriculture, logistics, and automotive. Different types of chains serve specific functions, and proper maintenance is essential for ensuring their longevity, efficiency, and safety.

1. Types of Industrial Chains

1.1 Roller Chains

• Application: Used in conveyors, motorcycles, and machinery for power transmission.

• Features: Consists of rollers, pins, and plates, designed for smooth motion and high efficiency.

1.2 Conveyor Chains

• Application: Found in automated assembly lines, food processing, and mining industries.

• Features: Built for heavy loads and designed to move materials over long distances.

1.3 Leaf Chains

• Application: Used in forklifts, hoists, and material handling equipment.

• Features: High tensile strength, made for lifting and pulling loads.

1.4 Lifting Chains

• Application: Used in cranes, rigging, and hoisting applications.

• Features: Designed for heavy loads and extreme durability.

1.5 Mining Chains

• Application: Used in underground mining, drilling rigs, and excavators.

• Features: Built for abrasion resistance, high tensile strength, and tough environments.

1.6 Stainless Steel Chains

• Application: Used in food processing, pharmaceutical, and marine industries.

• Features: Corrosion-resistant, ideal for wet and high-temperature environments.

1.7 Special Chains (Non-Standard Chains)

• Application: Custom-designed chains for unique industrial applications, such as escalators, bottling plants, and packaging machines.

• Features: Designed according to specific load, speed, and environment requirements.
  
  

2. Maintenance of Industrial Chains

Proper maintenance extends the lifespan of industrial chains and ensures efficient operation. Key maintenance practices include:

2.1 Lubrication

• Reduces friction and wear.

• Use appropriate lubricants based on the chain type and environment (e.g., oil-based for dry environments, grease for heavy loads).

• Apply lubrication regularly to prevent rust and corrosion.

2.2 Inspection and Cleaning

• Regularly check for wear, elongation, and cracks.

• Remove dust, dirt, and debris using a solvent or compressed air.

• Inspect rollers, pins, and plates for signs of fatigue or damage.

2.3 Tension Adjustment

• Ensure the correct chain tension to prevent excessive stretching or slack.

• Loose chains can cause slippage, while tight chains can lead to premature wear.

2.4 Corrosion Protection

• Apply anti-rust coatings or nickel plating for chains used in moist or corrosive environments.

• Store chains in dry, temperature-controlled areas when not in use.

2.5 Replacement of Worn Parts

• Replace stretched or deformed chains to avoid machine failure.

• Check and replace damaged sprockets or rollers for smooth operation.

2.6 Heat Treatment and Surface Hardening

• Some chains undergo quenching, tempering, or nitriding to enhance wear resistance.

• Shot peening helps improve fatigue strength for high-stress applications.

Conclusion

Industrial chains are critical components in various industries, and choosing the right type depends on the application. Proper lubrication, inspection, tension control, and protection ensure their long-term performance and durability. Regular maintenance not only prevents breakdowns but also reduces operational costs and enhances safety.
