電站測(cè)溫用熱電偶 WRNK-492
產(chǎn)品概述
WRNK-492是一種適用于電站測(cè)溫場(chǎng)景的鎧裝熱電偶,采用鎳鉻-鎳硅(K型)測(cè)溫元件,能夠直接測(cè)量0℃至1100℃范圍內(nèi)的液體、蒸汽、氣體介質(zhì)及固體表面溫度。該產(chǎn)品通過兩種不同導(dǎo)體材質(zhì)在溫差作用下產(chǎn)生的熱電勢(shì)原理工作,具有彎曲安裝、耐高壓和快速響應(yīng)的特點(diǎn)。其核心結(jié)構(gòu)由導(dǎo)體、絕緣氧化鎂和1Cr18Ni9Ti不銹鋼保護(hù)管經(jīng)拉制工藝成型,可根據(jù)實(shí)際需求選擇絕緣式或接殼式兩種測(cè)量端形式。2317
技術(shù)特性
該熱電偶的熱響應(yīng)時(shí)間在直徑Φ8mm規(guī)格下為4秒(接殼式)或8秒(絕緣式),能快速跟蹤溫度變化。常溫絕緣電阻在500V直流電壓測(cè)試下≥1000MΩ·m,確保電氣安全性。產(chǎn)品可選配固定卡套法蘭、螺紋等安裝方式,配套顯示儀表后可組成完整的溫度監(jiān)測(cè)系統(tǒng)。針對(duì)電站環(huán)境需求,其保護(hù)管采用整體深盲孔加工工藝,端部壁厚均勻,能有效應(yīng)對(duì)高溫高壓工況下的機(jī)械沖擊和振動(dòng)。3615
應(yīng)用場(chǎng)景
特別適用于發(fā)電機(jī)組鍋爐爐頂、蒸汽管道、軸承等關(guān)鍵部位的溫度監(jiān)測(cè)。在30萬/60萬千瓦機(jī)組中,可作為替代進(jìn)口產(chǎn)品的選擇,滿足輔機(jī)系統(tǒng)測(cè)溫需求。產(chǎn)品設(shè)計(jì)考慮了電站復(fù)雜環(huán)境下的可靠性,測(cè)溫元件與保護(hù)管采用分離式結(jié)構(gòu),支持不停機(jī)快速更換。對(duì)于DN100以上管道安裝時(shí),建議插入深度為管道直徑的1/2-2/3以確保測(cè)量準(zhǔn)確性。111320
產(chǎn)品配置
標(biāo)準(zhǔn)配置包含接線盒、鎧裝偶絲及固定裝置,可選防水/防濺接線盒以適應(yīng)不同環(huán)境。工作端形式提供單支或雙支結(jié)構(gòu),套管直徑涵蓋Φ3-Φ8mm,長度可按需定制(最長可達(dá)10米)。補(bǔ)償導(dǎo)線式設(shè)計(jì)簡化了現(xiàn)場(chǎng)布線,配套電子調(diào)節(jié)器或記錄儀表后可實(shí)現(xiàn)溫度數(shù)據(jù)的采集與控制。安裝時(shí)需避開閥門彎頭等紊流區(qū)域,優(yōu)先選擇流體穩(wěn)定段以確保測(cè)量穩(wěn)定性。4921
