Elevating Standards: Large Corporation's Technical Prerequisites for Conveyor Idlers

In this comprehensive document, we have provided an intricate insight into the technical requirements for the procurement of conveyor idlers by a prominent corporation. These requirements manifest a distinct emphasis on the safety, performance, and reliability of conveyor idlers, reflecting the vital role these components play in the company's operations. Equipment and components that conform to these rigorous standards will facilitate the uninterrupted movement of materials and goods, thus contributing to a significant reduction in maintenance expenses. For contractors and suppliers, meeting these challenging requirements presents a notable opportunity to engage in a valuable partnership. In summary, the specificity and stringent nature of these technical requisites highlight the company's unwavering commitment to ensuring that conveyor idlers meet the highest quality standards, resulting in prolonged service life and dependable performance.

The general technical requirements can be summarized as follows:
All documents should be in the International System of Units (SI).
Documents and drawings during the contract execution should be written in English and provided in electronic Autocad format.
Bidders are required to provide equipment that meets personal safety and labor protection requirements.
Spherical conveyor idler bearings should be designed and manufactured correctly to ensure safety and continuous operation, avoiding issues such as excessive stress, vibration, corrosion, aging, or other factors that could affect operation.
Equipment must be brand new and have a reliable design; the bidding party does not accept components and equipment with prototype status.
The manufacturing process of equipment components should have excellent craftsmanship and be easily disassembled, replaced, and repaired.
All materials should meet relevant specifications and be verifiably new and of high quality.
Strict quality management must be implemented during the equipment manufacturing process, including necessary processing, inspections, and testing.
conveyor idler components should possess good interchangeability and meet the environmental and operating condition requirements of the power plant's location.
Each conveyor idler must rotate flexibly, without any sticking. Lubrication components should have effective seals and not exhibit grease leakage. Bearings should be high-precision bearings from nationally recognized bearing manufacturers.
Metal welding should adhere to the relevant provisions of GB985 and GB986, with no defects such as burn-through, cracks, or incomplete fusion in the welds.

Specific requirements for the conveyor idlers are as follows:

conveyor idler bodies should be made of specialized high-frequency welded steel pipes for conveyor idlers, with a wall thickness of no less than 4mm, and the steel pipe manufacturer must be approved by the bidding party.
conveyor idlers should use specialized conveyor idler bearings, employing a labyrinth sealing method to meet dust and water resistance requirements. Stamped bearing seats, bearings, and seal rings should be injected with lithium-based lubricating grease. The oil filling quantity in the bearings should be 2/3 of the bearing clearance, and the gap between seal rings should be completely filled. Both bearings should maintain good concentricity.
The radial runout of the outer diameter of conveyor idler conveyor idlers (excluding special conveyor idlers such as cushion and comb types) should not exceed 0.5-0.6mm.
Under a 500N axial load, the axial displacement of the conveyor idler under normal working conditions should not exceed 0.7mm.
The conveyor idler's service life under normal working conditions should be no less than 50,000 hours, with a damage rate not exceeding 6% during its lifetime. After assembly, the conveyor idlers should undergo sampling inspections, with performance testing including dust resistance, water resistance, rotational resistance, and axial movement.
