GB/T 12784-2017 in English

GB/T 12784—2017 Standard Background and Technology Evolution

GB/T 12784—2017 Rubber and Plastics Pressure Kneading Machine is an important revision that replaces the original standard GB/T12784—1991. It has made a number of optimizations mainly for the needs of new technology and new product research and development. The new standard introduces stricter term definitions, model requirements and technical parameters, and adds safety and environmental protection requirements.

Comparison of Standard Frameworks

Interpretation of core clauses

5.2.1 Technical performance improvement: The hardness requirement of the rotor ridge and ridge side surface is increased to HRC40 to ensure wear resistance and service life.

5.2.7-5.2.8 Optimization of water pressure test: Increase the test duration and pressure multiples to enhance sealing performance and safety.

Analysis of professional terms

Implementation suggestions

1. Selection suggestions: Select the appropriate specifications according to the characteristics of the processed materials, and refer to Table A.1 for basic parameters.
2. Detection focus: Ensure that the grounding and insulation performance of the electrical system meet the requirements of GB/T5226.1-2008.
3. Maintenance: Regularly check the temperature rise of the rotor bearing and the lubrication of the reducer to ensure long-term stable operation of the equipment.
