Yes, we are an experienced manufacturer with our own production lines.Our Factory in Chang’an Xihu (West Lake) Dis. guang and office in HangZhou Shuibei Jewelry Center.

3.What is the jewelry’s maintenance?
1).Avoid making your jewelry get in touch with mordant liquid as far as possible, such as perfume, sweat, cleaner, sanitizer, water, shower gel when wearing.
2).To keep the gloss of your jewelry, you’d better to wipe it or clean and soft dry cloth after wearing.
3).Put your jewelry in your jewelry box to prevent it from contacting sunlight and damp air when you are not wearing jewelry for a long time.

4.Is the marking price on website is the final price for ordering?
Not exactly,the price range is only for reference,exact price is different base on product width, length, quantity,colors,market demand etc, so pls contact us to get final exact price,thanks for understanding.

Can double chains be used in vertical lifting applications?

Yes, double chains can be used in vertical lifting applications. Vertical lifting involves lifting or lowering loads in a straight-up or straight-down direction, and double chains are well-suited for this purpose due to their strength, reliability, and load-bearing capabilities. Here’s how double chains are suitable for vertical lifting:

1. High Strength: Double chains are designed to handle heavy loads and high-torque applications. Their construction with two rows of interconnected links provides increased strength and load-carrying capacity compared to standard roller chains.

2. Load Distribution: The two rows of links in a double chain help distribute the load evenly across the chain, reducing stress on individual components and enhancing overall chain performance during lifting operations.

3. Smooth Operation: Properly lubricated and maintained double chains offer smooth and efficient operation during lifting and lowering processes. This ensures stable and controlled movement of the lifted load.

4. Reliability: Double chains are known for their reliability and durability, which is crucial in vertical lifting applications where safety and precision are paramount.

5. Sprocket Engagement: Double chains engage securely with the sprockets, which is essential for maintaining stability and preventing slippage during the lifting process.

6. Design Versatility: Double chains are available in various sizes, pitches, and configurations, making it easier to select a suitable chain for specific vertical lifting requirements.

7. Safety Considerations: When using double chains for vertical lifting, it’s essential to adhere to safety guidelines and regulations. Proper installation, regular inspection, and correct tensioning are crucial to ensure safe and reliable lifting operations.

However, it’s important to note that the choice of chain for vertical lifting depends on the specific application requirements, load capacity, and environmental conditions. Consulting with a qualified engineer or chain supplier can help determine the most suitable double chain for a particular vertical lifting application.

What are the noise and vibration characteristics of double chains?

The noise and vibration characteristics of double chains can vary depending on several factors, including the chain’s design, material, and operating conditions. Here are some key points to consider:

  • Noise: Double chains generally produce some level of noise during operation. The noise is primarily generated by the interaction of the chain with the sprockets and the impact between the chain links and sprocket teeth. The noise level can be affected by factors such as chain tension, speed, lubrication, and the overall condition of the chain and sprockets. Proper lubrication and maintenance can help reduce noise levels.
  • Vibration: Double chains can also generate vibrations during operation, especially in high-speed applications. Vibrations are caused by the cyclic loading of the chain as it engages and disengages from the sprocket teeth. Excessive vibration can lead to increased wear, fatigue, and reduced overall system efficiency. To minimize vibrations, it is crucial to ensure proper tensioning, alignment, and lubrication of the chain.
  • Noise Damping: Some double chains come with features or attachments to dampen noise and vibration. These may include rubber or elastomeric components between the chain links or other forms of vibration-absorbing materials. Such designs can help reduce noise and vibration and improve overall system performance.
  • Enclosures and Guards: In noise-sensitive or high-precision applications, enclosing the chain and using guards can help contain noise and reduce the impact of vibrations on surrounding equipment and structures.

Proper installation, maintenance, and the use of suitable lubricants are essential to optimize the performance of double chains and minimize noise and vibration levels. Additionally, choosing the right type of chain and understanding the specific requirements of the application can contribute to a quieter and smoother operation.

How do double chains handle shock loads and impact forces?

Double chains are designed to handle shock loads and impact forces, providing robust and reliable power transmission in demanding applications.

The design and construction of double chains contribute to their ability to withstand shock loads and impact forces. Here are some ways double chains handle these dynamic loads:

  • High-Strength Materials: Double chains are typically made from high-strength materials such as alloy steel, which provides excellent tensile strength and resistance to impact forces. These materials help the chain maintain its structural integrity and prevent deformation or breakage under sudden and intense loads.
  • Enhanced Fatigue Resistance: Double chains are engineered to have enhanced fatigue resistance, allowing them to withstand repeated cycles of shock loads and impacts without premature failure. The materials and manufacturing processes used in double chain construction help improve their fatigue life and overall durability.
  • Optimized Chain Design: Double chains often feature specific design elements that help distribute and dissipate the forces generated by shock loads and impacts. These design features include thicker plates, larger pins, and hardened surfaces to improve load distribution and reduce stress concentration points.
  • Tight Clearances: Double chains typically have tight clearances between the pins and bushings, which provide added stability and reduce the potential for chain disengagement or skipping under sudden loads. The close-fit design helps maintain the chain’s integrity during impact events.
  • Proper Lubrication: Adequate lubrication is essential for the smooth operation and longevity of double chains. Lubrication helps reduce friction and wear, especially during high-impact situations. It also helps dissipate heat generated by friction, preventing overheating and premature failure.
  • Regular Inspection and Maintenance: Regular inspection and maintenance are crucial to identify any signs of wear or damage that may affect the chain’s ability to handle shock loads. Monitoring the chain’s condition and performing timely maintenance, such as lubrication, tension adjustment, and replacing worn-out components, ensure its optimal performance in high-impact applications.

It is important to consider the specific application requirements and consult the manufacturer’s guidelines when selecting and using double chains in high-impact environments. Adhering to recommended maintenance practices and ensuring proper installation and alignment will further enhance the chain’s ability to handle shock loads and impact forces effectively.
