上海压缩机厂研制的新产品2Z2-6/8型迷宫式空压机于 1986年10月 14日通过了技术鉴定。鉴定会由西安交大石华鑫教授主持。机械工业部合肥通用所,轻工部食品工业研究所,上海市经委,上海市机电工业局等31个单位的42位代表参加了鉴定。 上海压缩机厂研究所接受该项目以后,从设计到研制成功,共用了二年多时间。该机由于采用了迷宫密封环,从而取代了以往压缩机中常用的金属活塞环和填料函,其效果可与瑞士苏尔寿公司产品媲美,为发展我国食品机械工业填补了一项空白。
Shanghai Compressor Factory developed a new product 2Z2-6 / 8 labyrinth air compressor on October 14, 1986 passed the technical appraisal. Appraisal will be hosted by Xi’an Jiaotong University Shi Huaxin professor. 42 representatives from 31 units including Hefei General Machinery Institute of Ministry of Machinery Industry, Institute of Food Industry of Light Industry Ministry, Shanghai Economic Commission and Shanghai Mechanical and Electrical Industry Bureau attended the appraisal. Shanghai Compressor Factory Institute accepted the project, from design to successful development, shared more than two years. The machine uses a labyrinth seal ring, which replaced the previous compressor commonly used metal piston rings and stuffing box, the effect can be comparable with the Swiss company Sulzer, for the development of China’s food machinery industry to fill a blank.
