Kev kho cua sov kom sov ua ntej lossis tom qab kev lees txais ntawm ib lub sijhawm, raws li qhov ntsuas kub thiab qhov ntsuas kub ua raws cov qauv kev ua yuam kev. Daim ntawv no qhia cov qauv thiab cov cai ntsuas ntawm kev kho cua sov kom daws tau cov txheej txheem ntawm kev daws teeb meem kev ua siab ntev rau cov txheej txheem kev ntsuas qhov system.
1, qhov ntsuas qhov system raug xeem thiab cov hau kev
1.1, cov txheej txheem raug yuam kev ntsuas qhov xav tau
Kev kho cua sov rauv taws ua kom sov yog txhawm rau ntsuas qhov kub thiab txias ntawm qhov ntsuas kub ntawm qhov ntsuas kub los txiav txim siab seb qhov ntsuas kub ntsuas yog li ntawm qhov kev tso cai. Txoj kev ntsuas hluav taws xob yog hu ua qhov system raug ntsuas.
Kev kho cua sov kom sov yog ntsuas qhov ntsuas thiab tau ntsuas qhov tseeb ntawm qhov ntsuas kub, yog li cov kev xav tau ntawm qhov ntsuas kub thiab txias rau lossis siab dua ntsuas ntsuas qhov tseeb.
Txoj kab uas hla ntawm lub thermocouple hlau muaj cov kev nruj me ntsis: kev siv cov hauv qab no tsis ntau tshaj 540 degree ntawm tsis ntau tshaj 0.8 hli.
Txheeb xyuas qhov ntsuas kub ntawm qhov kev xaiv kuj tau thov kom meej. Kev xaiv ntawm kev pib calibration cov ntsiab lus kub: rau cov khoom siv nyob rau ntawm qhov ntsuas kub tshaj plaws hauv qhov ntsuas kub thiab txias rau txhua lub sijhawm ntsuas kub
Kev kho cua sov kom sov li cas ntawm kev ntsuas calibration kub taw tes yuav tsum tau ua nyob rau ntawm ib tug txheej txheem kub taw tes. Yog tias koj feem ntau siv kev ua haujlwm kub ntau, txhua zaus xwb tsuas yog xaiv qhov ntsuas kub qhov ntsuas kub, nyob rau hauv ib xyoos ntawm txhua qhov kub qhia hloov tau tseeb. Thaum qhov system raug xeem yog nqa tawm, nws yog qhov tsim nyog los tshawb xyuas thiab nyeem ntsuas ntsuas ntsuas thiab ntsuas ntsuas thaum ntsuas kub ntawm cov cua sov cua sov yog ruaj khov.
1.2, cov txheej txheem ntsuas qhov system
Tso qhov kev sim sim thermocouple nyob rau hauv tib qho kub thiab cua thermocouple ntawm calibrated system, qhov twg yog tsawg dua 75 mm. Ua ntej, xaiv cov txheej txheem ntsuas kub yuav tsum tau txheeb xyuas, cov cuab yeej siv lub tshuab hluav taws xob, tsuas yog siv lub tshuab nqus dej ua kom sov (Nyeem cov cuab yeej calibration, cov cuab yeej sim nyeem. Thiab kev ntsuas ntsuas tau sau cia. Lub tshuab nqus tsev ua hluav taws xob ntsuas hluav taws xob qhov tseeb kuaj tuaj yeem siv nrog kev tsim cov cua sov tib lub sijhawm.
Txhua qhov system uas yuav cuam tshuam qhov tseeb ntawm cov kab ke tom qab kev saib xyuas ntawm lub hauv paus yuav tsum tau rov ua dua tshiab, suav nrog kev hloov ntawm thermocouple thiab ntsuas kev hloov kho thiab ntsuas roj av.
2, Kev kho cua sov rauv taws qhov system yog kev sim ua cov txheej txheem feem ntau tshwm cov teeb meem thiab cov kev daws teeb meem
Nyob rau hauv cov txheej txheem ntawm cov txheej txheem kev xeem raug mob feem ntau vim muaj ntau yam ntawm cov xwm txheej, yog tias tsis muaj cov kev daws teeb meem, yog tias tsis tuaj yeem siv, cov khoom siv tsis tuaj yeem siv vim tias muaj kev pheej hmoo, ncua sij hawm ntau lawm. Nyob rau hauv xyoo tsis ntev los no, los ntawm kev kawm txuas ntxiv thiab tshawb nrhiav qee yam kev paub, peb tuaj yeem daws cov teeb meem hauv kev tsim khoom hauv txhua tus neeg los faib. Muaj ntau cov laj thawj rau kev ua siab ntev rau kev ua siab ntev, xws li kev cuam tshuam ntawm thermocrouple
Tsis tas li ntawd, muaj cov ntsuas kub thiab them nyiaj rau nws tus kheej, muaj qhov yuam kev thiab lwm yam. Feem ntau, tuaj yeem suav tau raws li cov twj paj nruag, them nyiaj xaim thiab kub teb ruaj khov ntawm cov laj thawj no, hauv qab no tau qhia.
2.1, cov laj thawj rau lub twj paj nruag
Kev kho cua sov sov sov sov qib tam sim no qib yog siab dua, tus nqi yuam kev feem ntau yog hauv qab 0. 2, yog li cov ntsuas yuam kev muaj nuj nqis yog qhov me me. Tab sis kuj tseem xav txog qhov kev ua tsis tiav lossis ib feem ntawm cov ntsuas tsis muaj digital. Nyob rau hauv lub tshav kub kho ntawm ib peb-cheeb tsam ntsuas rauv taws ua kom pom tias muaj ib txoj kev ntsuas kub thiab ntsuas qhov ntsuas kub, tom qab kev tswj hwm qhov kub thiab txias. Kev daws rau cov teeb meem no yog los hloov lossis kho cov twj paj nruag. Ntev npaum li qhov tseeb ntawm kev tswj qhov ntsuas kub thiab txias ua tau raws li qhov yuav tsum tau ua, qhov teeb meem yog ib qho yooj yim los daws.
2.2, nyiaj them rau cov laj thawj rau cov xaim
Kev kho cua sov kom sov sov nws yuav yog vim tias cov kev xaiv ntawm kev xaiv cov hlau hom thiab thermocouple tsis phim lossis them nyiaj rau xaim yuam kev los ntawm kev loj heev. Txoj kev tseeb yog xaiv cov hom raug thiab raug ntawm cov xaim hluav taws xob. Vim tias muaj kev them nyiaj rau qhov ua rau muaj kev ua yuam kev los ntawm cov xaim hluav taws xob feem ntau tau muab tso rau hauv cov khoom siv them nyiaj tshiab lossis hloov pauv cov khoom siv zoo, kom tiv thaiv cov teeb meem no.
2.3, qhov laj thawj ntawm thermocouple
Kev kho cua sov kom sov qhov no yog qhov yooj yim ntawm cov teeb meem. If the equipment some time ago its system accuracy to meet the requirements, and the temperature uniformity is better, but the last time the system accuracy test found that the accuracy of tolerance, the most likely reason is that the thermocouple in high temperature environment for some time after the use of even silk Organization and performance changes, and cause the accuracy of the thermocouple down, making the accuracy of the entire system tolerance.
2.4, qhov cuam tshuam ntawm txoj kev kuaj
Cov kev sim sib txawv los ua qhov tseeb ntawm qhov sib txawv tsis yog tib yam li cov tshuab nqus cub ua haujlwm, piv txwv li, lwm tus yog hom sab hauv. Thaum lub thermocouple yog nyob rau hauv chav tsev kub, qhov kub muaj cov nyhuv me me rau kev sib kis txias ntawm qhov thermocouple, yog li qhov ntsuas tau muaj tseeb; Lwm txoj hauv kev yog kev sib txuas sab hauv, lub tshuab nqus tsev yog nyob rau hauv lub tshuab nqus dej nruab nrab thiab yog li, qhov no yuav cuam tshuam rau qhov kev xeem siab txias txias.
2.5, qhov ruaj khov ntawm qhov kub
Qhov laj thawj ntawm cov cub hluav taws xob nws tus kheej: xws li lub qhov rooj kaw tsis nruj, ua rau kub tswj ntsuas kev hloov pauv kub, thiab yog li cuam tshuam rau kev kuaj mob system. Kev daws teeb meem yog txhim kho lub qhov rooj thiab lwm qhov chaw ntawm cov foob, txhim kho cov rwb thaiv tsev tag nrho ntawm cov cua sov.
2.6, qhov cuam tshuam ntawm ib puag ncig sab nraud
Kev kho cua sov kom sov sov peb tau tshwm sim hauv kev tsim cov twj kub thiab txias, qee zaum yuav muaj kev ntaus kub, qee zaum yuav muaj qhov nyuaj ntawm kev sim ua haujlwm. Tom qab ua rau ntawm kev tshawb nrhiav, pom tsuas yog vim muaj kev cuam tshuam sab nraud, ua rau muaj kev cuam tshuam nrog kev kub ntxhov ntawm qhov kub thiab txias thiab yog li cuam tshuam rau qhov ntsuas kub uas ua rau qhov kev hloov pauv loj. Qhov laj thawj kom paub, qhov teeb meem yog qhov yooj yim los daws. Peb yuav cais cov hlua hluav taws xob thiab them nyiaj xaim hlau kom deb, qhov deb ntawm ob qhov loj npaum li muaj peev xwm txo qhov hluav taws xob muaj zog ntawm cov tsis muaj zog. Siv cov khoom siv tiv thaiv tau siv los xav txog kev siv cov khoom them nyiaj ntawm cov khoom siv thiab kaw cov twj.
2.7, qhov cuam tshuam ntawm cov kub lub tshuab
Kev kho cua sov kom sov raws li cov kev cai ntawm Ams2750D, sau cov ntsuas kub thiab kaw cov ntsuas kub thiab txias. Tom qab cov kev ntsuas hloov kho tshiab ntawm Ams2750E Cov qauv ntsuas kub ntawm qhov ntsuas kub thiab txias rau qhov ntsuas kub thiab txias ntawm qhov kub thiab txias
