The company's quality management emphasizes customer satisfaction, market-oriented quality, economic quality, quality responsibility, and process-oriented quality.
Business Areas and Environmental Responsibility
The pewag group offers a diverse range of products, including traction chains, industrial chains, and DIY products. The company is committed to ecological awareness, aiming to improve energy efficiency and reduce environmental impact through modern manufacturing technologies and employee involvement.
Production and Sales Locations
The pewag group has a global presence with production and sales locations across Europe, North America, South America, Africa, Australia, and Asia. This international network ensures optimal customer service in over 100 countries.
Bucket Elevator Chains
pewag bucket elevator chains are made from high-quality alloyed steel, ensuring resistance to shock loadings and excellent fatigue strength. The chains are designed for high-temperature operations and manufactured with precise tolerances for smooth operation. The document details various chain systems, including the BDD-S and BHV systems, which are suitable for heavy-duty, high-capacity applications.
Assembly and Maintenance
The document includes instructions for assembly and maintenance of bucket elevator systems, ensuring longevity and optimal performance.
Specifications
The document outlines the specifications for different chain systems used in bucket elevators. It includes details on chain dimensions, materials, and load capacities. Chains are made from special alloyed steel, such as CrNi and MnCr, and are designed to handle high dynamic and static loads. The document specifies the production tolerances for chain lengths and the breaking and proof loads for different quality grades.
Components
Key components discussed include bucket elevator chains, chain couplings, connecting links, drive sprockets, and individual teeth. Each component is described with its dimensions, material specifications, and assembly instructions. The document emphasizes the importance of using matched pairs for chains and components to ensure precise alignment and smooth operation.
Procedures
The document provides assembly and disassembly instructions for various components, such as chain couplings and connecting links. It also includes guidelines for selecting the appropriate bucket attachment based on bucket size and discharge type.
Technical Data
Detailed tables provide technical data for different chain types, including HV and DS chains. The tables list chain dimensions, weights, proof and breaking loads, and surface hardness. Additional data on carburizing and case hardening depths are provided for specific chain sizes.
Recommendations
The document recommends using the next size up pitch chain shackle for friction drive systems and provides guidance on adapting sprockets to accommodate chain wear. It also suggests using shimplates and new teeth to maintain smooth chain operation over sprockets.
Conclusion
This technical document serves as a comprehensive guide for selecting, assembling, and maintaining bucket elevator chains and components. It provides essential information for ensuring the efficient and reliable operation of bucket elevators in handling bulk materials.
Specifications and Recommendations
- For chain wear, a quality grade E10 is recommended at approximately 3.5% wear, and E14 at 5%.
- In friction drive systems, chain replacement should occur at approximately 5% interlink wear.
- Maximum chain wear per link diameter should not exceed 1/5 of the new link diameter.
- Replace segments when vertical links run onto the groove base of the chain wheels.
- Ensure uniform loading across the full width of the buckets to prevent asymmetric wear and slanting buckets.
- Protect round steel chains from overloading or blocking with safety clutches or shear pins.
- Regularly check chains, connecting links, attachments, and chain wheels for damage, corrosion, or unusual wear.
- Check and retighten all screw connections as necessary.
- Replace chain couplings when the round steel chain is replaced.
- Avoid welding on chains, connecting links, or case-hardened components.
Bucket Elevator Questionnaire
- Collects detailed information about the material handled, including specific weight, grain size, temperature, moisture content, abrasiveness, corrosiveness, and chemical influences.
- Requires data on capacity, chain speed, shaft centers, and position of the bucket elevator.
- Inquires about the type of bucket elevator, whether it's a new installation, replacement, or modification, and the reasons for modification.
- Asks for service hours per year, power requirements, and dimensions of the casing.
- Requests details on chain centers, bucket elevator system type, bucket size standard, drive sprockets, chain diameter, quality grade, and number of links per chain end.
