Hauv kev ntsuas kub ntawm kev lag luam, Teflon-coated corrosion-resistant thermocouples thiab armored platinum kuj thermometers yog ob hom kub sensors. 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 hauv qab no muab kev sib piv zoo los ntawm ntau qhov kev pom los qhia meej lawv qhov sib txawv tseem ceeb.
I. Qhov txawv ntawm cov qauv tsim thiab kev teeb tsa
1. Teflon-Coated Corrosion-Resistant Thermocouples
Cov yam ntxwv tseem ceeb ntawm Teflon-coated corrosion- tiv taus cov thermocouples nyob hauv lawv cov Teflon txheej tiv thaiv thiab cov qauv hlau bimetallic. Lawv feem ntau siv Teflon (polytetrafluoroethylene) sheath los qhwv lub raj tiv thaiv hlau, nrog rau 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. Teflon sheath muaj kev ruaj ntseg 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 khoom siv tshuaj thiab tshuaj lag luam. Lawv txoj kev teeb tsa feem ntau suav nrog cov xov sib txuas lossis flange mounting, ua kom nruj haum nrog cov khoom siv saum npoo 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. Tus 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. Armored Platinum Resistance Thermometers
Cov yam ntxwv tseem ceeb ntawm armored platinum tiv thaiv tus pas ntsuas kub yog nyob rau hauv lawv cov hlau armor tiv thaiv thiab platinum hlau winding qauv. Lawv feem ntau siv lub raj tiv thaiv hlau (xws li cov hlau tsis muaj steel) txhawm rau txhawm rau platinum xaim - qhov chaw hnov mob, nrog cov khoom siv insulating sau rau sab hauv los ua ib qho khoom siv phom sij. Cov qauv tsim armored tso cai rau kev sojntsuam kom muaj kev ncaj ncees ntawm cov qauv hauv siab -kub, siab - siab, lossis vibrating ib puag ncig, thaum tseem pab txhawb cov teeb liab kis tau tus mob thiab kev saib xyuas. Piv txwv li, nyob rau hauv cov khoom noj khoom haus los yog kev lag luam kev lag luam, lub armored tsim kom muaj kev sib cuag txaus ntawm qhov kev sojntsuam thiab cov khoom siv nto, txo cov cua sov thaum lub sij hawm hloov cov txheej txheem. Nws cov qauv tsim qhia txog kev tiv thaiv nruj ntawm cov cuab yeej thiab kev ruaj ntseg ntawm platinum hlau. Cov armor txo cov kev cuam tshuam ntawm ib puag ncig yam ntawm kev ntsuas qhov tseeb thiab txhim khu kev tiv thaiv rau txhua yam kev co thiab kev poob siab. Txawm li cas los xij, nws cov txheej txheem kev teeb tsa yuav tsum tau ua kom ntseeg tau tias cov cuab yeej ua tiav hauv 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, cov hlau platinum tuaj yeem muaj kev hloov pauv hauv kev tiv thaiv vim muaj kev ntxhov siab hloov pauv thaum lub sijhawm siv sijhawm ntev -.
II. Qhov txawv ntawm Cov Cai Ua Haujlwm
1. Txoj Cai Ua Haujlwm ntawm Teflon-Coated Corrosion-Resistant Thermocouple
Lub thermocouple yog raws li cov nyhuv Seebeck, qhov twg ob qhov sib txawv hlau conductors tsim 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 sheath txuas 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 Armored Platinum Resistance Thermometer
Tus pas ntsuas kub platinum kuj yog raws li cov yam ntxwv uas cov hlau tsis kam hloov nrog qhov kub thiab txias. Nws tus nqi tsis kam muaj qhov tsis muaj -txoj kev sib raug zoo nrog kub thiab yuav tsum tau txiav txim siab los ntawm kev sab laj ib lub rooj lossis siv cov qauv (xws li, Pt100 muaj qhov tsis kam ntawm 100Ω ntawm 0℃, thiab tus nqi kuj nce linearly nrog nce 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 meej hauv nruab nrab thiab qis kub (-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 qhov ntsuas qhov tseeb. Cov qauv tsim armored tso cai rau nws kom muaj kev ntsuas kev ntsuas ruaj khov hauv qhov chaw kub kub.
