Tsim Tus Kws Kho Mob Field's Secret Riam Phom: Qhov kawg Thermocouple Bench Kit
Xav txog tej yam nyob rau hauv ib qho kev pab hu rau lub malfunctioning cua sov system. Tus tswv tsev tsis muaj cua sov, kev kuaj mob taw tes rau qhov teeb meem ntawm qhov ntsuas kub, tab sis qhov tshwj xeeb thermocouple hom lossis ntev tsis paub. Yog tsis muaj qhov zoo, lub chaw kho. Qhov xwm txheej no qhia txog qhov xav tau tseem ceeb rau cov kws tshaj lij: kev npaj. Ib qho ntawm cov tswv yim zoo tshaj plaws yog sib sau ua ke tus kheej, cov khoom siv thermocouple "lub rooj zaum."
Lub thermocouple yog ib qho tseem ceeb sensor pom nyob thoob plaws suav tsis txheeb siv cua sov. Nws ua haujlwm ntawm lub hauv paus ntsiab lus yooj yim: ob qhov sib txawv ntawm cov hlau sib xyaw ua ke ntawm ib qho kawg ua kom muaj qhov hluav taws xob me me, uas tuaj yeem kwv yees tau thaum qhov kev sib tshuam yog cua sov lossis txias. Lub teeb liab millivolt no sib haum rau qhov kub thiab txias. Txawm hais tias cov kev tshawb fawb tseem ceeb sib xws, cov ntawv thov xav tau sib txawv heev. Piv txwv li, lub compact, ceev- teb cov thermocouple saib cov nplaim hluav taws nyob hauv phab ntsa- dai boiler. Hauv qhov sib piv, lub tshuab hluav taws xob hauv pem teb cua sov yuav siv lub sheathed, grounded thermocouple embedded nyob rau hauv lub screed kom ruaj, ntev -lub sij hawm tswj kub. Lub tshuab hluav taws xob muaj hluav taws xob tuaj yeem siv cov khoom siv hluav taws xob, siab -kub version. Tus kws tshaj lij hauv teb, yog li ntawd, ntsib ntau yam xav tsis thoob hauv cov ntaub qhwv, txoj kab uas hla, qhov sib txuas, thiab lub taub hau txuas.
Tsim kom muaj qhov zoo- cov khoom siv txiav txim siab hloov lub sijhawm ua haujlwm. Lub hom phiaj tsis yog los nqa txhua qhov kev xav tau hloov pauv, tab sis kev xaiv cov tswv yim uas suav nrog feem pua ntawm cov chaw hloov pauv thiab tso cai rau kev kuaj mob ib ntus.
Cov khoom siv tswv yim pib nrog ntau hom universal. Nrog rau kev xaiv cov qauv ntxhia-insulated, hlau- sheathed (MIMS) thermocouples hauv Hom K thiab Hom J yog qhov tseem ceeb. Kev sib xyaw ntawm qhov ntev, los ntawm 6 mus rau 24 ntiv tes, thiab cov kab dav dav dav xws li 1/4 "thiab 3/16" nyob rau ntau qhov chaw nyob thiab kev lag luam cua sov. Ob qho tib si grounded thiab ungrounded junction style yuav tsum sawv cev; ib qho kev sib tshuam hauv av muab cov lus teb sai dua rau kev kuaj mob, thaum qhov tsis muaj kev cuam tshuam feem ntau xav tau rau cov tshuab uas qhov kev sib cais hluav taws xob tseem ceeb heev.
Kev sib txuas yog ib qho kev ua tsis tiav. Cov khoom siv yuav tsum muaj ntau yam ntawm cov qauv ntsaws- thiab - qhov (socket) txuas (qhov me me thiab cov qauv loj) thiab cov taub hau hloov pauv. Qhov ntev ntawm cov nyiaj them rov qab txuas ntxiv ntawm tib hom (piv txwv li, KX) nrog cov khoom sib txuam yog qhov muaj txiaj ntsig zoo rau kev ntsuas cov ntsuas hauv qhov nyuaj - mus rau - mus txog qhov chaw. Cov cuab yeej siv yooj yim xws li lub tshuab txiav me me, cov ciaj ntswj kho tau, thiab siab - kub sealant kuj yog cov khoom tseem ceeb ntawm cov khoom siv.
Txawm li cas los xij, muaj cov khoom tsuas yog ib nrab ntawm kev sib ntaus sib tua. Ob peb cov lus qhia ua kom muaj kev vam meej. Nco ntsoov xyuas hom thermocouple. Txhim kho hom J qhov twg yuav tsum muaj Hom K yuav muab kev nyeem yuam kev, raws li qhov voltage-rau- qhov kub thiab txias nkhaus sib txawv. Thaum routing lub sensor tshiab, zam kev khoov ntse uas tuaj yeem ua rau cov xov hlau sab hauv puas thiab tsim cov ntsiab lus kev ntxhov siab. Nws kuj tseem pom zoo kom khaws cov thermocouple kom deb ntawm cov khoom siv hluav taws xob sib nqus siab thaum ua tau. Rau cov tshuab uas muaj kev tswj xyuas hluav taws xob me me, kev lees paub seb pawg tswj hwm puas xav tau qhov kev soj ntsuam hauv av lossis tsis muaj av yog ib kauj ruam tseem ceeb uas tuaj yeem tiv thaiv kev hu rov qab.
Hauv cov ntsiab lus, tus kws tshaj lij cov khoom siv thermocouple lub rooj ntev zaum yog ntau tshaj li cov khoom sib sau; nws yog ib qho cuab yeej rau kev ua tau zoo thiab kev ntseeg tau. Nws txhawb cov kws tshaj lij los kuaj xyuas kom raug thiab daws cov teeb meem tam sim. Thaum lub qhov dej - cov khoom ntim khoom lag luam ua haujlwm ntau ntawm kev kho ntau yam, nws qhia txog lub ntsiab lus dav dua: kev ua haujlwm zoo ntawm lub pob khawm ntawm qhov tseeb specification thiab kev teeb tsa ntawm txhua yam. Qhov no yog qhov tseeb tshwj xeeb rau cov kev daws teeb meem cua sov. Xaiv thiab tso cov sensors rau kev ua haujlwm zoo hauv ntau lub tshuab-los ntawm cov cua sov hauv qab hauv qhov qhib- npaj layout rau zoned radiator tswj hauv ntau-zaj dab neeg hauv tsev- yuav tsum tau ua tib zoo tsim. Thaum kawg, kev nplij siab txhim khu kev qha yog nyob ntawm ob qho tib si zoo ntawm cov khoom siv hauv cov khoom siv thiab cov kev txawj ntse uas tau muab tso rau hauv thawj qhov kev tsim qauv thiab commissioning.
