Introduction
Interpretation of the core content of the standard
This standard is applicable to the import inspection of special equipment for manufacturing ceramic insulators, such as vacuum kneading machines, presses, and ball mills, and focuses on regulating:
| Inspection dimensions | Key indicators | Testing methods |
|---|---|---|
| Mechanical safety | Joint surface gap ≤1mm, screen surface flatness, anti-leakage powder design | Visual inspection + functional test |
| Temperature rise control | Bearing temperature rise ≤30K, mud section temperature rise ≤10K | Infrared detection + recorder |
| Protective device | Interlocking device, curtain protection, rotor brake | Functional verification |
Analysis of key technical requirements
4.2.1 Mechanical safety
Taking vacuum mud kneading machine as an example, the standard emphasizes:
- The spiral connection part has a smooth transition, and the measured gap needs to be ≤1mm
- The temperature rise of the extruded mud section needs to be controlled within the range of 10K
4.2.3 Non-mechanical safety
For vacuum mud kneading machine, the standard emphasizes:
- The spiral connection part has a smooth transition, and the measured gap needs to be ≤1mm
- The temperature rise of the extruded mud section needs to be controlled within the range of 10K
4.2.4 Non-mechanical safety class=instrument>press and ball mill: - Rolling bearing temperature upper limit of 70℃
- Main bearing oil return temperature of ≤55℃
Implementation suggestions
Inspection process optimization
It is recommended to adopt a three-stage inspection method:
- Pre-arrival document review (technical agreement/drawing)
- Key dimension verification when unpacking
- 72 hours continuous operation test after installation
Troubleshooting
For crusher feed inlet protection:
- The curtain material should be wear-resistant rubber
- Protective devices must pass a 500N static pressure test

Compared with the 2013 version of SN/T 3700, this part adds:
- Pressure machine material distribution system anti-leakage requirements
- Crusher rotor maintenance lock clause
- Specify the quantitative index of temperature rise
