Nyob rau hauv lub tshav pob ntawm kev ntsuas kub, raug cov thermocouples thiab tsau flange mounted 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 kev sib piv hauv qab no los ntawm ntau qhov ntev yuav qhia meej txog lawv qhov sib txawv tseem ceeb.
I. Qhov txawv ntawm cov qauv tsim thiab kev teeb tsa
1. Tshem tawm Thermocouple
Lub ntsiab feature ntawm qhov raug thermocouple yog tias nws ntsuas qhov kawg yog ncaj qha mus rau qhov ntsuas nruab nrab, tsis tas yuav tsum muaj kev tiv thaiv ntxiv. Nws feem ntau yog ua los ntawm ob lub xov hlau sib txawv (xws li npib tsib xee-chromium thiab npib tsib xee-silicon) welded ua ke los tsim qhov ntsuas kawg, uas yog ncaj qha tso rau hauv qhov ntsuas nruab nrab. Nws txoj kev tsim qauv qhia txog kev sib cuag ncaj qha thiab teb sai. Qhov tsim tawm ntawm qhov ntsuas qhov kawg tso cai rau nws nkag siab qhov hloov pauv ntawm qhov nruab nrab qhov kub thiab txias, ua rau lub sijhawm teb ceev heev, ua rau nws tsim nyog rau cov xwm txheej uas yuav tsum tau ntsuas qhov ntsuas kub tam sim. Piv txwv li, hauv kev ua zaub mov lossis kev lag luam tshuaj, cov khoom siv thermocouples tuaj yeem saib xyuas qhov kub thiab txias hloov hauv cov kua lossis roj, ua kom muaj kev nyab xeeb ntawm cov txheej txheem ntau lawm. Txawm li cas los xij, cov txheej txheem kev teeb tsa yuav tsum ua kom ntseeg tau tias qhov ntsuas qhov kawg yog raus tag nrho hauv qhov ntsuas nruab nrab, uas ua rau kom qhov nyuaj ntawm kev teeb tsa. Tsis tas li ntawd, cov hlau hlau yuav oxidize los yog corrode nyob rau hauv siab - kub los yog corrosive ib puag ncig, cuam tshuam rau ntev - lub sij hawm stability.
2. Tsau Flange Mounted Platinum Resistance Thermometer
Lub ntsiab feature ntawm lub flange mounted platinum kuj tus pas ntsuas kub yog nws ruaj flange kev twb kev txuas thiab platinum hlau winding qauv. Nws feem ntau siv lub flange ruaj khov (xws li DN50) los txuas rau qhov chaw ntawm cov khoom raug ntsuas los ntawm bolts. Sab hauv, platinum hlau yog qhov txhab ntawm cov pob txha los yog cov pob txha mica los ua qhov ntsuas kub ntawm qhov ntsuas kub, uas tom qab ntawd txuas rau sab nraud los ntawm lub thawv sib txuas. Lub thawv sib txuas tsim ua kom yooj yim rau cov teeb liab sib kis thiab kev saib xyuas, thaum tseem muab kev tiv thaiv tsis muaj dej thiab plua plav. Piv txwv li, hauv kev ua zaub mov lossis kev lag luam tshuaj, qhov kev tsim flange ruaj khov ua kom muaj kev sib raug zoo ntawm qhov kev sojntsuam thiab cov khoom siv saum npoo, txo cov cua sov thaum lub sijhawm hloov hluav taws xob. Nws cov qauv tsim qhia txog kev sib txuas ntawm lub flange thiab kev ruaj ntseg ntawm platinum hlau. Tus tsim flange ruaj khov txo qhov cuam tshuam ntawm ib puag ncig yam ntawm kev ntsuas qhov tseeb thiab txhim kho kev tiv thaiv kev poob siab thiab tshuaj lom neeg corrosion. Txawm li cas los xij, nws cov txheej txheem kev teeb tsa yuav tsum ua kom ntseeg tau tias lub flange yog kiag li nyob rau hauv kev sib cuag nrog rau saum npoo ntawm cov khoom raug ntsuas, uas ua rau kom lub complexity ntawm installation. Tsis tas li ntawd, lub thawv sib txuas yuav raug txo qis kev ua tau zoo thaum lub sij hawm vim yog ib puag ncig.
II. Qhov txawv ntawm Cov Cai Ua Haujlwm
1. Txoj Cai Ua Haujlwm ntawm Cov Thermocouples Exposed
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 qhov tso zis voltage hloov ntawm kwv yees li 5-40 microvolts. Lawv cov qauv yog qhov yooj yim, tsis muaj qhov txav txav, ua rau lawv haum rau siab -kub, siab-siab, thiab corrosive ib puag ncig. Cov qauv tsim tawm tso cai rau lub sijhawm teb sai dua, tab sis kev saib xyuas yuav tsum tau them rau oxidation thiab corrosion ntawm cov hlau xaim.
2. Txoj Cai Ua Haujlwm ntawm Flange Mounted Junction Box Hom Platinum Resistance Thermometers
Platinum resistance thermometers yog raws li cov yam ntxwv uas cov hlau tsis kam hloov nrog qhov kub thiab txias. Lawv cov nqi tsis kam muaj qhov tsis zoo -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 yog qhov yooj yim, tsis muaj qhov txav txav, ua rau lawv haum rau kev ntsuas qhov tseeb hauv nruab nrab mus rau qhov kub thiab txias (-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. Tus tsim flange ruaj khov tso cai rau kev ntsuas kev ua haujlwm ruaj khov txawm tias nyob hauv qhov chaw kub kub.
