Hauv kev ntsuas kub ntawm kev lag luam, Teflon-coated corrosion- tiv taus cov thermocouples thiab ruaj khov- xov sojntsuam- hom platinum tiv thaiv tus pas ntsuas kub yog ob hom kev ntsuas kub. Lawv muaj qhov sib txawv tseem ceeb hauv kev tsim qauv, cov qauv kev ua haujlwm, cov yam ntxwv ntawm kev ua haujlwm, thiab cov xwm txheej ntawm daim ntawv thov. Cov kev sib piv hauv qab no yuav qhia txog lawv qhov sib txawv tseem ceeb.
I. Qhov txawv ntawm cov qauv tsim thiab kev teeb tsa
1. Teflon-Coated Corrosion-Resistant Thermocouple
Lub ntsiab feature ntawm Teflon -coated corrosion- resistant thermocouple nyob rau hauv nws Teflon sheath tiv thaiv thiab bimetallic hlau qauv. Nws feem ntau yog siv Teflon (polytetrafluoroethylene) sheath los qhwv lub raj hlau tiv thaiv, nrog ob txoj hlua hlau sib txawv (xws li npib tsib xee-}chromium thiab npib tsib xee- silicon) welded ua ke sab hauv los ntsuas qhov kawg. Lub Teflon sheath muaj kev ruaj ntseg tshuaj zoo heev thiab tuaj yeem tiv thaiv corrosion los ntawm cov kua qaub uas muaj zog, muaj zog hauv paus, thiab cov kuab tshuaj organic, ua rau nws tsim nyog rau corrosive ib puag ncig xws li cov tshuaj thiab tshuaj industries. Nws txoj kev txhim kho feem ntau yog threaded kev twb kev txuas los yog flange kho, xyuas kom nruj haum nrog cov khoom nto los txhim kho kev ntsuas qhov tseeb thiab cov lus teb ceev. Piv txwv li, nyob rau hauv ib tug tshuaj reactor, lub Teflon sheath tiv thaiv lub thermocouple los ntawm corrosive media, thaum lub threaded kev twb kev txuas tso cai rau kom ceev installation. Nws cov qauv tsim qhia txog kev tiv thaiv corrosion ntawm lub sheath thiab kev ywj pheej ntawm cov xov hlau bimetallic. Teflon sheath txo qhov cuam tshuam ntawm ib puag ncig yam ntawm kev ntsuas qhov tseeb thiab txhim khu kev tiv thaiv rau cov neeg kho tshuab poob siab. Txawm li cas los xij, cov txheej txheem kev teeb tsa yuav tsum ua kom ntseeg tau tias cov sheath nyob rau hauv kev sib cuag nrog qhov chaw ntawm cov khoom raug ntsuas, uas ua rau kom qhov nyuaj ntawm kev teeb tsa, thiab cov xov hlau bimetallic tuaj yeem oxidize nyob rau hauv siab - qhov kub thiab txias ib puag ncig, cuam tshuam ntev - lub sij hawm stability.
2. Tsau -Thread Probe-Type Platinum Resistance Thermometer
Cov yam ntxwv tseem ceeb ntawm qhov ruaj khov- xov sojntsuam- hom platinum tiv thaiv tus pas ntsuas kub nyob hauv nws cov xov txuas ruaj khov thiab platinum hlau winding qauv. Nws feem ntau siv cov xov ruaj khov (xws li M20 × 1.5) kom ua tiav kev teeb tsa ruaj khov los ntawm kev ntsia hlau rau hauv qhov chaw ntawm cov khoom raug ntsuas. Sab hauv, platinum xaim yog qhov txhab ntawm lub ceramic lossis mica thav duab los ua qhov kub thiab txias -sensing element. Cov xov ruaj ruaj tsim kom muaj kev sib txuas ntawm qhov kev sojntsuam thiab cov khoom siv nto, ua rau nws haum rau siab -siab lossis daim ntawv thov uas yuav tsum tau ntsuas ntev ntev -. Piv txwv li, hauv kev ua zaub mov lossis kev lag luam tshuaj, cov xov xov ruaj khov tsim kom ntseeg tau tias qhov kev sojntsuam tseem nyob ruaj khov ntawm - cov kav dej siab, txo qhov cuam tshuam ntawm kev co ntawm kev ntsuas. Nws cov qauv tsim qhia txog kev sib txuas ntawm cov xov hlau kho thiab kev ruaj ntseg ntawm platinum hlau. Cov xov ruaj ruaj tsim txo cov kev cuam tshuam ntawm ib puag ncig ntawm kev ntsuas qhov tseeb thaum txhim kho kev tiv thaiv rau cov neeg kho tshuab poob siab thiab tshuaj lom neeg corrosion. Txawm li cas los xij, cov txheej txheem kev teeb tsa yuav tsum tau ua kom ntseeg tau tias cov xov muaj kev sib cuag nrog lub ntsej muag ntawm cov khoom raug ntsuas, uas ua rau kom qhov nyuaj ntawm kev teeb tsa. Tsis tas li ntawd, kev sib txuas ntawm threaded tej zaum yuav loosen vim kev co thaum lub sij hawm ntev - siv, cuam tshuam rau kev ntsuas qhov tseeb.
II. Qhov txawv ntawm Cov Cai Ua Haujlwm
1. Txoj Cai Ua Haujlwm ntawm Teflon-Coated Anti-Corrosion Thermocouple
Thermocouples yog raws li cov nyhuv Seebeck, qhov twg ob lub hlau conductors sib txawv ua kom muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias. Thaum ob lub hlau conductors txuas nrog rau tsim ib lub voj voog kaw, thiab ob qhov kev sib txuas muaj qhov sib txawv ntawm qhov kub thiab txias, ib qho hluav taws xob hluav taws xob tsim tawm hauv Circuit Court. Qhov loj ntawm lub zog no muaj feem xyuam rau cov khoom siv thiab qhov kub thiab txias sib txawv ntawm cov junctions. Los ntawm kev ntsuas lub zog electromotive, qhov ntsuas kub tuaj yeem suav tsis ncaj. Thermocouples muaj siab rhiab heev; 1℃qhov kub thiab txias hloov ua rau muaj peev xwm hloov pauv ntawm kwv yees li 5-40 microvolts. Lawv cov qauv yooj yim thiab tsis muaj qhov txav txav ua rau lawv haum rau siab -kub, siab-siab, thiab corrosive ib puag ncig. Qhov sib ntxiv ntawm Teflon txheej ntxiv nthuav dav lawv daim ntawv thov ntau yam, tso cai rau lawv ua haujlwm ruaj khov nyob rau hauv ib puag ncig corrosive heev.
2. Txoj Cai Ua Haujlwm ntawm Kev Tshawb Fawb Cov Xov Tooj Tsau -Type Platinum Resistance Thermometer
Platinum resistance thermometers yog raws li cov yam ntxwv uas cov hlau tsis kam hloov nrog kub. Tus nqi tsis kam muaj qhov tsis yog -txoj kev sib raug zoo nrog kub thiab yuav tsum tau suav nrog cov ntxhuav lossis cov qauv (piv txwv li, Pt100 muaj qhov tsis kam ntawm 100Ω ntawm 0 degree, thiab tus nqi kuj nce linearly nrog nce kub) los txiav txim qhov ntsuas kub. Platinum kuj thermometers muaj siab rhiab heev; 1℃qhov kub thiab txias hloov ua rau muaj kev hloov pauv tseem ceeb hauv cov nqi tiv thaiv. Lawv cov qauv yooj yim thiab tsis muaj qhov txav txav ua rau lawv tsim nyog rau kev ntsuas qhov tseeb ntawm qhov nruab nrab thiab qis qis (-200℃txog 600 degree), tab sis muaj zog sib nqus teb los yog cov neeg kho tshuab vibrations yuav tsum tau zam kom tsis txhob cuam tshuam kev ntsuas qhov tseeb. Txoj hlua ruaj khov tsim tso cai rau lawv tswj kev ntsuas kev ntsuas ruaj khov txawm tias nyob hauv qhov chaw kub kub. III. Kev Qhia Txog Tus Kheej
