Kev tsom xam ntawm cov ua kom ua haujlwm ua haujlwm hauv cov hnav thermocoist

Hnav Cov Tiv Thaiv Kev Tiv Thaiv Thermocoup yog cov khoom tshwj xeeb thermocouple kev faib tawm. Nws yog ib lub ris tiv thaiv-tiv thaiv thaiv cov raj tiv thaiv feem ntau yog ntawm cov pa tshuaj pleev xim rau tshuab, cov roj ntsha siab cam, thiab cov khoom siv kub siab. Nws tuaj yeem raug kho rau cov chaw kub ib puag ncig thiab haum rau siv nyob rau hauv Circulating Fluidized txaj, boiling rhuab hluav taws, thiab cement cotary liles. Tseem muaj ntau yam kev ua txhaum nyob rau hauv kev siv ntawm cov kev hnav thermocoive, thiab saib xyuas yuav tsum tau them rau qee cov ntsiab lus. Kev daws teeb meem tsuas yog suav nrog kev ceev faj hauv qab no :.

1. Lub rwb thaiv cov txheej ntawm cov xaim hluav taws xob ntawm cov ris-resistant thermocouple yog hnav tawm, sib sau lub teeb liab corcuit Court. Qhov no yog feem ntau yog vim muaj qhov tseeb tias cov hlau roj ntsha yog qhov nyuaj thiab tsis tso ntsia hauv lub thawv hlws ris. Thaum cuam tshuam nrog cov teeb meem, pheej sib ntswg lub hlws ris lub thawv npog yuav ua rau nws nkag mus rau hauv cov xaim hluav taws xob thiab hnav nws tawm. Qhov teeb meem no tau cuam tshuam hauv qhov ntsuas kub qhia rau tus neeg teb xov tooj tswj chaw nres tsheb, uas feem ntau qis dua.

2. Cov nqi xaim hluav taws xob ntawm cov ris-resistant thermocouple yog thim rov qab. Qhov no yog qhov teeb meem uas tseem ceeb tshaj tawm thaum lub sijhawm ua haujlwm, tshwm sim los ntawm kev lam ua ntawm cov neeg ua haujlwm lub luag haujlwm, uas yog vim yog neeg yam ntxwv. Thaum cov khoom them nqi hlau ntawm cov thermocouple yog thim rov qab, cov zaub ntawm tus neeg teb xov tooj tswj chaw nres tsheb feem ntau yog tus nqi tiag tiag (nyob ntawm seb ntsuas hluav taws xob).

3. Tsis muaj kev sib cuag tsis zoo ntawm cov xaim hluav taws xob hauv lub thawv hlws ris. Vim tias lub hardness ntawm cov xaim xaim thiab thermocouple xaim, nws yog qhov nyuaj rau kev siv hluav taws xob thaum lub sijhawm txij nkawm thaum lub sijhawm txij nkawm thaum lub sijhawm txij nkawm thaum lub sijhawm txij nkawm thaum lub sijhawm txij nkawm thaum lub sijhawm txij nkawm thaum lub sijhawm txij nkawm. Qee zaum, cov hlau loj zuj zus thaum pib tab sis yuav xoob dua tom qab lub sijhawm vim yog deformation ntawm xaim. Qhov teeb meem no yog xav txog hauv qhov ntsuas kub qhia rau tus neeg teb xov tooj tswj chaw nres tsheb yog tsis muaj zaub lossis cov nqi tshwm sim ntau tshaj qhov ntau.

4. Them nyiaj tiv thaiv tsis tau zoo. Hom teeb meem no ua rau muaj kev nce qib qeeb lossis txo qis hauv kev nyeem ntawv kub tom qab qhov thermocouple txuas nrog.

5. Qhov tsis ua hauj lwm ntsuas ntsuas kub hauv lub Tail FLUE ntawm BOILERS yog qhov siab. Thaum lub taub hau thermocouple tau kaw rau kev saib xyuas, nws tau pom tias lub taub hau thermocouple, suav nrog lub tes tsho tiv thaiv, yog cov hnav loj heev vim yog cov yaig ntawm cov pa luam yeeb. Lub tes tsho tiv thaiv yog ua los ntawm cov khoom-resistant steel khoom siv rau tshem tawm qhov kev phom sij uas zais.

6. Qhov ntsuas kub cov teeb liab teeb liab tom qab dhau los ntawm kev cais tawm ntawm tus neeg siv hluav taws xob tsis zoo rau ntawm tus neeg teb xov tooj tswj chaw nres tsheb. Ib txwm tom qab hloov tus raug rho tawm. Qhov saum toj no yog cov teeb meem tshwm sim thaum lub sijhawm txij nkawm, nws raug nquahu kom ua ntej siv cov tswv yim hluav taws xob muaj nuj nqis rau ntawm DCS. Qhov no tuaj yeem ua qhov txawv sai tias nws yog ib qho teeb meem nrog lub chaw ntsuas ntsuas ntsuas lossis ntu DCS. Rau cov lus qhia ntau tshaj tawm, nws kuj tseem tuaj yeem muab piv nrog cov cim los ntawm ntau lwm cov thermocouples. Yog tias tus nqi tiv thaiv tsis tuaj yeem txiav txim siab los ntawm kev ntsuas txoj kab ntxiv, tus nqi tiv thaiv ntawm cov hnav-resistant thermocouple feem ntau yog ib puag ncig 100 ω.

7. Kev tsis zoo hauv av sab hauv dcs txee ntawm lub teeb liab shielding system. Qhov teeb meem no yog nquag mus rau kev tsub zuj ntawm cov nqi ntawm cov teeb liab kab, ua rau cov teeb liab drift lossis jitter. Vim tias qhov teeb meem nyuaj rau kev txheeb xyuas, qhov kev daws teeb meem dav dav yog txhawm rau txiav cov teeb liab kab thiab ua kom muaj kev tawm tsam nws.
