一种凝汽器钛管在线快速查漏方法的探讨与应用张翠华1 ,21 . 武汉大学动力与机械学院 ,湖北 武汉4300722 . 广东粤电靖海发电有限公司 ,广东 靖海515223[ 摘要 ]常规的解列凝汽器半侧查找钛管漏点的方法盲目性较大且不实用 。为此 ,建立了用于判断漏点区间的数学模型 ,并对凝汽器检漏装置进行改进 ,按照先判定泄漏点所在的水 室再锁定管排最后确定漏点的方法 ,可快速发现泄漏点 。广东粤电靖海发电公司超临界 2 ×600 M W 机组凝汽器钛管的检漏证实 ,该方法能准确快速地找到漏点的位置 ,值得推广。凝汽器 ;钛管 ;在线查漏 ;数学模型 ;解列T K264 . 1 + 1B1002 - 3364 (2009) 08 - 0137 - 0410 . 3969/ j . i ssn . 1002 - 3364 . 2009 . 08 . 137[ 关 键 词 ][ 中图分类号 ] [ 文献标识码 ] [ 文 章 编 号 ] [ DOI 编 号]A N APP ROAC H TO THE O N L I NE RAPID L EA KA GE SEA RC HI NGM ETHOD A ND APPL ICATIO N THEREOFh ua1 ,2Z H A N G Cui -1 .
