scraper conveyor chain

The scraper conveyor chain can be used to transport bulk materials in horizontal, inclined and vertical directions. It is often used for the transportation of raw grain, semi-finished products and finished products in grain and oil, feed processing plants. The scraper conveyor chain is suitable for the transportation of oil in the production process of grease processing plants. Transportation of raw grain from grain warehouse. 

It has the advantages of simple structure, good sealing, simple feeding and unloading device, multi-point feeding and unloading, flexible layout, and the ability to complete material transportation in multiple directions at the same time. The scraper conveyor chain of ZheJiang CHINAMFG Chain Factory adopts medium carbon quenched and tempered steel and cold heading die steel. The steel is moderately priced and easy to process. After proper heat treatment, a certain degree of toughness, plasticity and wear resistance can be obtained. Normalizing can promote the spheroidization of the structure and is suitable for surface hardening treatments such as high-frequency quenching and flame quenching. Application: After quenching and tempering, it can be used to manufacture medium load and medium speed work. The working principle of the scraper conveyor is to use the open chute as a bearing part for coal, gangue or materials, and fix the scraper on the chain (to form a scraper chain) as a traction member. When the driving part of the machine head starts, the sprocket on the driving head shaft rotates, so that the scraper chain circulates and moves the animal material along the chute until it reaches the machine head to unload. The scraper chain bypasses the sprocket and runs in a stepless closed loop to complete the transportation of materials. Other scraper conveyor chain uses and maintenance precautions have to be communicated with the supplier.

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 signs of wear and when should a double chain be replaced?

Identifying the signs of wear in a double chain is important for determining when it needs to be replaced. Here are some common signs of wear to look out for:

• Chain Elongation: Over time, a double chain can elongate due to wear on the pins, bushings, and rollers. Excessive chain elongation can cause poor engagement with the sprockets and lead to inaccurate power transmission. Measuring the chain’s pitch length using a chain gauge can help determine if it has elongated beyond the acceptable limits.
• Increased Noise and Vibration: As a double chain wears, it can produce increased noise and vibration during operation. Excessive noise and vibration may indicate worn or damaged components, such as worn rollers or elongated bushings.
• Visible Signs of Wear: Inspect the chain for visible signs of wear, such as worn or deformed rollers, elongated or distorted bushings, or heavily worn sprocket engagement surfaces. Additionally, check for signs of corrosion or rust, as these can also contribute to chain degradation.
• Stiffness and Resistance: A worn double chain may exhibit stiffness or resistance when flexing or moving. This can be due to the increased friction caused by worn components or inadequate lubrication.
• Frequent Chain Failure or Breakage: If the double chain is experiencing frequent breakage or failure, it is a clear indication of significant wear or damage. This can be a safety hazard and should prompt immediate replacement.

It is recommended to regularly inspect the double chain for these signs of wear and perform maintenance tasks such as lubrication and tension adjustment. However, if any of the above signs are evident, or if the chain has reached its maximum allowable elongation, it is necessary to replace the chain promptly to avoid potential equipment damage, reduced performance, and safety risks.

What are the different types of double chains available in the market?

There are several types of double chains available in the market, each designed to meet specific application requirements. Here are some common types:

• Standard Double Chain: This is the most basic type of double chain, featuring elongated links with double the pitch length compared to standard roller chains. It is widely used in general conveying and low-speed power transmission applications.
• Hollow Pin Double Chain: This type of double chain has hollow pins in the elongated links, allowing for easy attachment or customization. It is often used in applications where additional attachments or accessories need to be added to the chain.
• Extended Pin Double Chain: Extended pin double chains have longer pins in the elongated links, which provide increased flexibility for attaching various types of flights, buckets, or other specialized attachments.
• Flanged Double Chain: Flanged double chains feature extended flanges on the side plates, providing additional stability and guidance for conveying applications. They are commonly used in applications that require precise positioning or guidance of the chain.
• Side Bow Double Chain: Side bow double chains are designed with special side plates that allow the chain to bend or flex laterally. This type of chain is suitable for applications where curved or serpentine conveying paths are required.
• Specialty Double Chains: In addition to the standard types, there are specialty double chains available for specific industries or unique applications. These chains may have specialized features such as corrosion resistance, high-temperature resistance, or enhanced strength to withstand demanding environments.

It’s important to select the appropriate type of double chain based on the specific requirements of your application. Consider factors such as load capacity, operating conditions, environmental factors, and attachment compatibility when choosing the right double chain for your needs.
