【摘要】 R53C-Y旋转成型压机是核燃料芯块压制成型工序的关键设备,其主压部件上压辊架在运行过程中磨损比较严重。建立上压辊架部件的力学模型,作受力分析和计算;然后分析上压辊架磨损情况,对压机中央润滑系统存在的问题进行深入讨论;最后,根据核燃料芯块压制工况特点,开展技术革新,探索采用先进的油气润滑技术,在市场调研基础上对压机中央油气润滑系统进行应用设计,具有可操作性。旨在减缓磨损,降低故障率,提高压机工作可靠性和核燃料芯块生产现场清洁度;同时,为压机国产化创新提供了理论依据和新的思路。更多还原

【Abstract】 The rotary molding press R53C-Y is the key facility in the compression molding working procedure of the nuclear fuel pellets.Its main compression assembly called the upper compression roller frame has been worn seriously during the production.At first,the mechanical model of the upper compression roller assembly was established for analysis and calculation physical strength.Then the wear causations of the upper compression roller frame were analyzed,and the existent problems of central lubrication system were discussed.Finally,Oil-air central lubrication system was designed considering the characteristic of nuclear fuel pellets production.更多还原
