1.氫電導率,就是將檢測水樣先通過一個陽離子交換柱,水樣中的陽離子被離子交換樹脂中的氫交換,通過交換柱的水樣留有陰離子和交換下來的氫離子,然后測定電導率。

1. Hydrogen conductivity is testing the water through a cation exchange column, the cations in water are ion exchange resin in the hydrogen exchange, through the column of water exchange with anion and exchange down hydrogen ions, and then the electrical conductivity was measured.

2. 氫電導率抑制了氨對水汽品質檢測的影響，電廠熱力系統中為了防止金屬腐蝕,普遍采用給水加氨處理。氨是揮發性物質,除了與碳酸反應消耗一部分外也基本上留在熱力系統循環,系統中氨含量大約在１～３mg/Ｌ。而在機組正常運行時,在除鹽水、凝結水、蒸汽中的其他雜質成份含量也基本上是微克級,這毫克級的氨造成普通電導率檢測不能反映其他雜質成份,所以通過陽離子交換柱將銨根去除后,檢測電導率就能準確反映水汽中陰離子的含量。

2. Hydrogen conductivity suppress the effects of ammonia on the steam quality testing, and plant system in order to prevent metal corrosion, commonly used water plus ammonia. Ammonia is a volatile substance, in addition to part of the outer carbonate reaction consumes basically stay in the loop thermodynamic system, the system ammonia content of about 1 ~ 3 mg/Ｌ. While in the normal operation of the unit. In in salt water, condensed water and steam in the other impurities content is basically microgram level, the mg ammonia caused by ordinary conductivity detection does not reflect other impurity elements, so by cation exchange column ammonium after removal, conductivity test can accurately reflect the content of anions in water vapor.

3. 氫電導率能準確反映凝汽器泄漏。例如:以海水作為凝汽器冷卻水的某機組,凝汽器發生微量的短時的泄漏,其他在線儀表還沒有反映,而氫電導已經有明顯的變化。

3. Hydrogen conductivity can accurately reflect the condenser leak. For example: to seawater as cooling water in a condenser unit, condenser leak small amounts of short-term occurrence, other online meter has not been reflected, while the hydrogen conductivity have been significant changes.

4.電廠要重視氫導電率表的作用，根據氫電導率的大小變化,進行水汽控制,是目前最直接、簡便、有效的檢測手段。它能及時、準確地反映水汽質量的變化,能靈敏地告訴運行人員水質變化,并通過對導電度數據變化規律的分析,可以尋找水汽質量變化的原因。

4. Power should pay attention to the role of hydrogen conductivity meter, according to the hydrogen conductivity change in size, were vapor control, it is the most direct, simple, effective means of detection. It can timely and accurately reflect the quality of the water vapor changes, can sensitively tell operating personnel changes in water quality, and by analyzing the variation of the conductivity of the data, you can find the reasons vapor quality change.
