Product Description

Industry heavy duty injection molding POM-C Derlin Acetal plastic flexible transmission convey leaf chain

POM (Polyformaldehyde)
 
POM (Full-name: Polyformaldehyde), is a engineering plastics of non-side-chain, high density, high crystalline and linear polymer, which is praised “Plastic Steel”, and has comprehensive excellent performances, such as: wear-resistance, high hardness, anti-impregnant, good rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional stability. POM has widely applied in Automobile industries, electronic and electric products, commodity, pipeline & fittings, exact apparatus and so on, which can be instead of the bronze, Zinc, tin and other metals.
 
Except POM-H, is often copolymerized with ethylene oxide together, in order to avoid the melting of POM material in the high temperature. POM-H has the better performances than POM-C in its high crystalline, mechanical strength and rigidity. And POM-C has the better performances than POM-H in its low melting point, temperature stability, fluxion characteristic and machining capability.
Father more, POM-H+PTFE, which is made from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the low co-efficient of frication, good lubrication, wear-resistance, non- creepage resistance.
 
Automobile industries: POM has a large application in car industries, because the mechanical parts made by POM, which has the advantages of high mechanical strength, high hardness, good wear-resistance, low co-efficient of friction, easy to maintain, reducing cost and so on, can be used in cars instead of coppery half stalk and planet gear. It not only saving copper materials, but also improving service life. At the engine fuel system, components for hose valves and case cover of radiator, cooling fluid’s standby case, water valve, oil box’ cover, pump impeller, shell of gasification machine and accelerator pedal and so on.
 
Electronic and electric Industries: because of its lower power consuming, high dielectric strength and insulation resistance and electronic arc resistance,  POM has widely applied in electronic and electric Industries, such as: shell of electronic spanner, shell of electronic scissors, shell of coal drilling machine ,handle of switch, parts also for phone, wireless recorder, video tape recorder, television, computer, electrograph, calculagraph, bracket of recorder tape and so on.
 
Agricultural machine: part of manual sprayer, joint and transport part of seeder, parts of milk machine, shell of irrigation and drainage, valve, joint and bush of water and so on.
 
Other field:
Pharmacy & packing Machine: transporting screw, planet gear, gear bar, chain wheel and cushion bar and so on.
Construction industries: water tap, window frame, wash pot, water tank, pulley for portiere, shell of water meter and tie-in of water pipe.

What are the safety considerations when working with leaf chains?

Working with leaf chains involves several important safety considerations to ensure the well-being of personnel and the proper functioning of the lifting equipment. Here are some key safety considerations:

  • Proper Installation: Leaf chains should be installed correctly according to the manufacturer’s guidelines and specifications. Improper installation can lead to chain failure and accidents.
  • Regular Inspection: Regularly inspecting the leaf chains for signs of wear, damage, or misalignment is essential. Any issues should be addressed promptly to prevent potential hazards.
  • Load Limits: Adhere to the load limits specified by the chain manufacturer. Overloading the leaf chain can result in excessive stress and may cause it to fail.
  • Environmental Considerations: Consider the operating environment of the leaf chain, such as temperature, moisture, and chemical exposure. Some environments may require special chain coatings or materials for optimal performance and safety.
  • Training and Certification: Operators and maintenance personnel should receive proper training in the safe use, inspection, and maintenance of leaf chains. Certification may be required for specific lifting operations.
  • Chain Lubrication: Proper chain lubrication is essential to reduce friction, wear, and the risk of chain failure. Follow the manufacturer’s recommendations for lubrication frequency and type.
  • Replacement of Worn Components: If any part of the leaf chain shows signs of wear or damage beyond acceptable limits, it should be replaced promptly with the appropriate spare part.
  • Clear Communication: Maintain clear communication among all personnel involved in the lifting operation to ensure coordinated and safe movements.
  • Emergency Procedures: Have clear emergency procedures in place in case of chain failure or accidents. This includes emergency stop controls and evacuation plans.

By following these safety considerations and adhering to industry standards and regulations, users can enhance the safety and reliability of working with leaf chains in lifting applications.

Remember that safety is paramount when working with any lifting equipment, and taking a proactive approach to safety can prevent accidents and injuries in the workplace.

Can leaf chains be used in railway maintenance and repair equipment?

Yes, leaf chains can be used in railway maintenance and repair equipment, and they offer several advantages in such applications.

Railway maintenance and repair equipment, such as rail trolleys, lifting systems, and track maintenance machines, often require robust and reliable lifting and pulling mechanisms to handle heavy loads and perform maintenance tasks efficiently. Leaf chains are well-suited for these applications due to the following reasons:

  • High Load Capacity: Leaf chains are designed to handle heavy loads, making them suitable for lifting and pulling tasks involved in railway maintenance.
  • Durability: Leaf chains are constructed from high-quality materials and undergo precision manufacturing processes, ensuring their durability and resistance to wear and fatigue.
  • Low Stretch: Leaf chains have low elongation, providing accurate and consistent movement, which is essential in precise maintenance and repair tasks.
  • Wide Temperature Range: Leaf chains can operate effectively in a wide range of temperatures, making them suitable for railway maintenance equipment used in different environmental conditions.
  • Adaptability: Leaf chains are available in various sizes and configurations, making them adaptable to different railway maintenance and repair equipment.
  • Reliable Performance: Leaf chains offer stable and reliable performance, minimizing the risk of equipment failure during critical maintenance operations.

Whether it’s lifting railway components, positioning track sections, or performing other maintenance tasks, leaf chains can provide the necessary strength and reliability required in railway maintenance and repair equipment.

However, it’s essential to choose the appropriate chain size, ensure proper lubrication, and conduct regular maintenance to ensure optimal performance and safety in railway maintenance operations.
