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 MW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。

Abstract

The conventional leakage-searching method is to find the leak points with stoppage of half condenser

having larger blindness

and being unpractical.For this

a mathematic model for judging the zone

in which the leak points exist

has been established

and the leakage-seaching facility being retrofitted.According to the method of firstly judjing the water chamber

in which the leak-point is located

nextly locking out the leaking row of tubes

and finally determining the leak point

thus

the leak point can rapidly be discovered.The leakage-searching of titanium tubes used in condenser of supercritical 2×600 MW units in Jinghai Power Generation Co Ltd proves that the location of leak-point can accurately and rapidly be found out by using the said method

being worth to be popularized to other thermal power plants.
