Dab tsi yog qhov txhaum ntawm qhov chaw -mounted gasket-hom thermocouples
Tso lus
Tsawg Thermoelectric Potential (Qhov ntsuas kub ntsuas qis dua qhov tseeb)
Qhov no yog qhov teeb meem tshaj plaws, cuam tshuam rau kev tswj xyuas qhov tseeb.
Lub gasket tsis muaj zog ua ntej -tightening force
Cov bolts tsis tau nruj tom qab kev teeb tsa, lossis ntev ntev -lub sij hawm kub kub annealed lub gasket hlau, txo nws compression thiab rebound kev ua tau zoo thiab clamping quab yuam. Qhov no ua rau huab cua sib txawv ntawm qhov ntsuas kub ntsuas qhov kawg thiab ntsuas qhov saum npoo, nce kev sib cuag thermal.
Tighten nrog lub torque ciaj ntswj mus rau tus qauv torque thiab tshuaj xyuas thiab hloov cov hnub nyoog gaskets.
Qhov kub tsis zoo ntawm qhov chaw sib cuag
Cov roj stains, oxide coatings, carbon deposits, los yog qhov chaw tsis sib xws hamper tshav kub conduction, ua rau kub lag los yog qis dua nyeem ntawv.
Kev daws: Ntxuav thiab txhuam qhov ntsuas kub hauv cheeb tsam ua ntej kev teeb tsa rau hlau -rau -hlau tiv tauj.
Intrusion ntawm noo noo los yog txo thermocouple rwb thaiv tsev
Dej thiab cov plua plav conductive tuaj yeem nkag mus ntawm cov thermoelectrodes thiab cov casing hauv lub thawv sib txuas lossis cov raj tiv thaiv vim tsis zoo sealing, txo cov teeb liab tawm.
Kev daws: Qhuav lub thermocouple core, tshuaj xyuas thiab hloov lub nplhaib sealing, thiab xyuas qhov kev sib txuas ntawm lub thawv sib txuas.
Teeb meem nrog them nyiaj hlau
Moisture, rwb thaiv tsev degradation, thim rov qab polarity, thiab them nyiaj xaim -thermocouple mismatches ua yuam kev. Kev siv E- hom them nyiaj xaim nrog K- hom thermocouple yuav tsis raug them nyiaj rau cov kab mob khaub thuas.
Kev daws: Hloov nrog cov xaim sib npaug sib npaug, xyuas cov polarity, thiab cov khoom siv dej tsis sib haum.
II. Siab Thermoelectric Potential (Display kub siab dua qhov tseeb)
Txawm tias tsis tshua muaj, qhov teeb meem no cuam tshuam rau kev txiav txim siab.
Thermocouple tsis raug- tso saib kev sib tw
Yog tias lub thermocouple yog K- hom tab sis qhov ntsuas yog S- hom, tib lub thermoelectric tej zaum yuav raug to taub yuam kev raws li qhov kub ntau dua vim qhov sib txawv calibration.
Kev daws: Match thermocouple thiab ntsuas ntsuas hom. Sab nraud qhov hluav taws xob cuam tshuam nce qhov kub ntawm qhov sib txuas.
Cov xaim them nyiaj los yog lub thawv sib txuas yog nyob ze ntawm qhov chaw siab - qhov kub thiab txias, nce qhov kub ntawm qhov sib txuas ntawm qhov ntsuas tus nqi thiab tsim cov khoom siv hluav taws xob tsis zoo thiab kev nyeem ntawv siab.
Kev daws: Zam kom tsis txhob muaj cua sov los ntawm kev ua kom zoo ntawm txoj kab hluav taws xob thiab txhim kho cov ntaub thaiv npog.
III. Cov teeb liab tawm tsis ruaj khov (hloov tus nqi tsis tu ncua)
Kev nyeem cov ntsuas ntsuas tsis sib xws cuam tshuam tsis siv neeg tswj kev ruaj ntseg.
Gaskets loosening los yog vibration ua kev sib cuag
Ntev- lub sij hawm vibration ntawm lub twj tso kua mis thiab cov kiv cua tuaj yeem txo cov bolts fastening, ua rau qee lub sijhawm ntsuas qhov ntsuas qhov kawg ntawm kev sib cuag tsis ua haujlwm.
Kev tiv thaiv - loosening gaskets los yog ob npaug -nut locking qauv thiab kev co damping brackets yuav pab tau.
Kev sib cuag tsis zoo lossis oxidation ntawm cov xaim
Yog hais tias cov xov hlau txuas tsis tau nruj los yog raug kub, qhov kev sib cuag ntawm qhov chaw oxidizes thiab teeb liab variations tshwm sim.
Kev daws: ntxuav qhov chaw tiv tauj, kho cov xaim, thiab siv tshuaj tiv thaiv - oxidation conductive paste yog tias xav tau.
Intermittent thermocouple tawg
Kev qaug zog lossis kev puas tsuaj me me ua rau micro- tawg nyob rau hauv cov thermocouple hlau, tsim kom muaj kev sib cuag nyob rau hauv kev co thiab teeb liab cuam tshuam.
Kev daws: Siv ib lub multimeter los ntsuas kev tiv thaiv Circuit Court; hloov lub thermocouple tam sim yog tias nws hloov pauv.
Hluav taws xob cuam tshuam
Cov kab hluav taws xob cuam tshuam qhov hluav taws xob tuaj yeem tshwm sim los ntawm kev sib nqus sib nqus nyob ze ntawm cov khoom siv hluav taws xob muaj zog xws li inverters thiab motors.
Kev daws: Muab cov ntaub thaiv npog rau ntawm ib kawg ntawm cov ntaub thaiv npog tiv thaiv cov xov hlau thiab ua kom lawv nyob deb ntawm cov kab hluav taws xob.
IV. Tsis muaj thermoelectric tej zaum tso zis (tsis muaj zaub lossis yuam kev)
Qhov no feem ntau qhia tau hais tias lub teeb liab Circuit Court tawg.
Hlau thermocouple tawg
Lub thermocouple hlau tawg vim kev txhim kho khoov, siab -kub embrittlement, lossis kev puas tsuaj.
Yog tias txoj haujlwm so tso cai, txiav thiab rov ua dua; txwv tsis pub, hloov nrog lub thermocouple tshiab.
Qhib Circuit Court lossis tsis tsim nyog them nyiaj xaim xaim
Cov kab hluav taws xob tawg yog los ntawm cov xov hlau raug sib cais, sib tsoo, lossis tsis raug xaim (qhib Circuit Court). Txhawm rau nrhiav thiab kho qhov chaw tawg, xyuas qhov txuas txuas ntxiv hauv qhov chaw.
Kev Tiv Thaiv Kev Tiv Thaiv Cov Lus Qhia
Cov kauj ruam hauv qab no tuaj yeem nce qhov chaw -mounted gasket-hom thermocouple kev ntseeg tau:
Tsis txhob xoob los ntawm kev kuaj xyuas lub bolt txhua lub hlis twg ua ntej- zawm quab yuam thiab gasket mob.
Standardize installation: Khaws qhov ntsuas kub ntawm qhov kawg ntawm kev sib cuag nrog lub ntsej muag huv kom tsis txhob yuam kev sib dhos.
Txhim khu kev tiv thaiv ib puag ncig: foob lub thawv sib txuas thiab fim lub cable tso tawm downwards kom tsis txhob ya raws thiab plua plav.
Teem lub voj voog calibration: Txhua 6-12 lub hlis, nyob ntawm qhov kev ua haujlwm, ntsuas qhov ntsuas ntawm qhov chaw lossis offline kom paub tseeb qhov ntsuas qhov tseeb.
