Introduction
1. Background and significance of standard formulation
GB/T 33931—2017 "Requirements for the repair process of the top sheave and guide sheave of mine hoists" is to standardize the repair process of key components of mine hoists and ensure the safety and reliability of equipment. This standard is formulated based on the actual needs of the mining machinery industry and combines years of practical experience and technological progress.
2. Comparative analysis of standard frameworks
| Chapter | Content overview | Differences from GB/T10599 | Implementation focus |
|---|---|---|---|
| Scope (Chapter 1) | Clearly define the scope of application and repair process methods. | Added a distinction between single-rope winding type and multi-rope friction type. | Ensure that the equipment type is correctly identified. |
| Normative references (Chapter 2) | List all necessary reference standards. | Align with international general standards. | Ensure that the repair materials meet the requirements. |
| Repair process methods (Chapter 3) | Detailed provisions for defect handling and repair processes. | Added specific requirements for non-destructive testing. | Ensure that the repair quality is traceable. |
3. Implementation recommendations
Preparation before repair:It is recommended to conduct a comprehensive inspection of the equipment, record all defects, and develop a repair plan based on standard requirements.
Precautions during the repair process:Strictly follow the process flow, especially the sandblasting and painting process to ensure the anti-corrosion effect.
Verification after repair:Conduct a static balance test to ensure the stability of the equipment operation.
