从内压变化与管路壁厚和管径之间的关系出发,通过分析不同种类材料性能对CO2跨临界制冷系统的管路系统可靠性的影响,发现管路系统的可靠性与管径的大小成反比,与管壁厚度和材料的许用应力成正比,找出了高压下系统运行可靠度的变化规律及提高可靠度的措施。
Based on the relationship between the change of internal pressure and the pipe wall thickness and pipe diameter, by analyzing the influence of different kinds of material properties on the piping system reliability of CO2 transcritical refrigeration system, it is found that the reliability of pipe system and the pipe diameter Inversely proportional to the size, and wall thickness and allowable stress of the material is proportional to find the system under high pressure operating reliability changes and measures to improve reliability.
