摘要
秦山二期D302大修期间对两台CRF鼓型滤网停机检修．检查发现鼓型滤网两侧轮毂存在不同程度的裂纹，并有进一步扩展的趋势，其中一台鼓型滤网左侧轮毂已经形成贯穿性裂纹，严重影响鼓型滤网的正常稳定运行。通过分析认为鼓型滤网轮毂的自身结构和轮毂的自身材料是导致鼓型滤网轮毂开裂的根本原因。据此对鼓型滤网轮毂进行了修复，彻底消除了缺陷。
Two CRF drum filters are overhauled for downtime during Qinshan II NPP D302 capital repair. Through the inspection, hubs in both sides of CRF drum filters have different degrees of cracks, and the cracks show further expansion trend. In the left hub of one drum filter, have been formed penetrating cracks, which seriously affects the normal and stable operation of the drum filter. It was found that the structure and the material of the drum filter hub are the root causes leading to the cracks. According to the conclusions, the drum filter hubs have been pertinently repaired, and the defects of the drum filter hubs are thoroughly eliminated.
