Introduction
Interpretation of the standard for filter model compilation method
1. Background and significance of the standard
GB/T7780-2016 "Filter Model Compilation Method" is a model compilation standard applicable to industrial filters, replacing the previous GB/T7780-2005 version. The standard was proposed by the China Machinery Industry Federation and is managed by the National Technical Committee for Separation Machinery Standardization.
The main revisions to the standard include adding terms and definitions, updating characteristic codes, adding new filter types, and optimizing model representation methods to meet the needs of industry technology development.
2. Comparison of Standard Frameworks
| Standard Version | Main Revisions | Scope of Application |
|---|---|---|
| GB/T7780-2016 | Added new terms and definitions; optimized characteristic codes; added filter types (such as stacked screw type and filter material type). | Applicable to the compilation of industrial filter models. |
| GB/T7780-2005 | Mainly stipulates basic codes, characteristic codes and main parameters, and does not include some new filter types. | The scope of application is consistent with the new standard, but lacks coverage of new technologies. |
3. Recommendations for the implementation of the standard
3.1 Model compilation principles
- The model consists of a basic code, a characteristic code, main parameters and a material code.
- The basic code is classified according to the type, type and characteristics of the filter, and the characteristic code is optional.
- The main parameters are represented by Arabic numerals, and the units must be clearly marked (such as m²/m or mm).
3.2 Implementation considerations
- When selecting the characteristic code, give priority to the indicator that best represents the characteristics of the filter.
- For new filters, additional definitions need to be made in combination with the standard framework.
- Model compilation should comply with industry naming practices and ensure traceability.
