Introduction
Standard Overview and Technical Evolution
JB/T 13178-2017 is my country's first dedicated industry standard for negative pressure powder and particle conveyors. It is managed by the Machinery Industry Food Machinery Standardization Technical Committee (CMIF/TC 14). This standard fills a gap in the standardization of pneumatic conveying equipment in the food, chemical, and other fields. Compared to traditional mechanical conveying methods, it focuses on the hygiene requirements and energy efficiency indicators unique to negative pressure pneumatic conveying.
Definition of core terms
| Terms | Definition | Technical significance |
|---|---|---|
| Dead zone | Residual area that cleaning medium cannot reach | Directly affects the hygiene level of equipment |
| MTBF | Mean time between failures ≥400h | Core reliability indicators |
| Conveying temperature rise | Material temperature rise ≤3℃ | Prevent denaturation of heat-sensitive materials |
Key technical requirements
5.1 General Specifications
- Structural Hygiene: Meet the dual requirements of GB 16798 and GB/T 19891
- Welding Quality: Weld Smoothness ≤0.2mm Roughness
- Sealing Performance: Leakage Rate <0.5% under 0.4-0.6MPa working conditions
5.3 Electrical Safety
Case Study: A milk powder production line had static electricity accumulation due to excessive grounding resistance (0.15Ω). By installing a copper grounding electrode, the resistance was reduced to 0.08Ω, meeting the standard requirement of ≤0.1Ω.
Performance Parameter Comparison
| Parameters | Pneumatic Type (Q) | Electric Type (D) | Test Method |
|---|---|---|---|
| Working Noise | ≤78dB(A) | ≤75dB(A) | GB/T 3768 Envelope Method |
| Energy Consumption Ratio | 0.8kW·h/t | 1.2kW·h/t | Material Conversion |
Implementation Suggestions
Purchase acceptance
- Verify the silo dead zone test report
- The vacuum degree in the on-site test reaches -98kPa
- The amount of residual material needs to be weighed with a balance with an accuracy of 0.1g
Maintenance points
- Replace the grease that complies with GB 15179 every 500 hours
- Quarterly check the fatigue cracks in the welding parts
- Annual insulation test needs to be carried out when the humidity is less than 70%
