I. THAWJ KEV TXIAV TXIM LOS NTAWM ROTER QAUV NTAULICAL 1. Cov qauv: Peb cov khoom tau tshaj li. Ntawd yog, lub cev kub thiab lub qhov cub sib txawv yog qhov tseeb ntawm lub logo {} Cov qauv khoom "thiab cov qauv khoom lag luam xws li kub tshaj plaws. Puas yog CE cim luam tawm sab nraub qaum? 2. Kev Siv Hluav Taws Xob Rhaub Averial: Qhov hluav taws xob hluav taws xob hluav taws xob hluav taws xob, λ {}} (2 {16} μm. Feem ntau cov khoom muaj kev nqus tau zoo nyob rau hauv lub wavelength. Qhov ze dua cov rhaub qhov t, qis dua nws λ, thiab muaj zog nws nkag mus. Raws li Wayne txoj kev cai lij choj, qhov ze ze qhov deb, ntau dua hluav taws xob siv)}}}} chromium {}}}}}}}}}}}}}}}} Raws li Ohm txoj cai: r=u² / p, tus nqi resistance yuav raug suav. Lub hwj huam P ↑, kam tawm tsam r ↓, thiab cua sov hlau thermium (+ {}}}}} silicon ({39}}); Kuj: 0.3 {{{}} 5ω. K - Hom thermocots muaj qhov yuam kev ntawm ± 0.4% t thaum ntsuas kub. Qeb; Qhov siab tshaj plaws tuaj yeem ncav cuag 1000 ° C, ib ntus li ntawm 1200 ° C; 3. Ceramic lub cev mis; 4. Thermal rwb thaiv tsev: thi: aluminium silicate; 5 6. Kab sab nraud: ① Tsible Collor: Stranded hlau, 2.5 mm², 11a, npib tsib, 500 ° C Max; ② xaub Thermocouple: khoom hlau, npib tsib xee, 400 ° C Max; Cov hlau nyiaj them hlau: Cov hlau pov tseg, 1.5 mm², 100 ° C Max. IV. Kev Txhim Kho Tiv Thaiv Hlau: Mounting Qhov 15 × 40, Mounting Phaj Thickness ≤1,5 ​​hli; V. Rhaub Zoo Kev Soj Ntsuam: 1. Rhaub Qhov Kev Tshawb Xyuas Zoo Tsis Muaj Thermocouple: ① Yuav suav tau siv Ohm Txoj Cai: R= u² / p. Yog tias ntsuas tus nqi ntsuas deviates los ntawm theoretical tus nqi tsis pub dhau + /- 6%, qhov no yog qhov qub. Kev tsis kam sib txawv sib txawv ntawm ntau qhov kub. Yog tias tsis nyob hauv qhov no, thov hu rau peb tus neeg sawv cev muag rau kev hloov kho kom ua haujlwm rau ua {103 ① khij cov hlau cua sov li rau cua sov tsis muaj thermocouples. ② Yog tias kauj ruam 1 kuaj xyuas zoo, txuas ntxiv ntsuas qhov thermocouple resistance ntawm lub rhaub; Nws yuav tsum nyob nruab nrab ntawm 0.3 thiab 1ω. ③ Tom qab siv hluav taws xob raug, lub zog rau ntawm rhaub rau 20 feeb thiab sim cov quab yuam thermoelective hla ntawm thermocouple. Yog hais tias lub thermoelectromotive quab yuam tseem sawv, thermocouple yog suav hais tias yog freatic. (Yog tias muaj cov teeb meem zoo, thov hu rau peb tus neeg sawv cev muag kom tau hloov.) VI. Kev ceev faj ua ntej siv: 1. Thermocouple hom ntais ntawv yuav tsum phim lub buoller- xaim xaim xaim hluav taws xob kom raug. Qhov kawg nrog tsaus ntsuab cim ntawm Thermocouple hlau yog qhov kev ua haujlwm ntawm cov haujlwm thiab siv tus nqi kub thiab txias VII. Cov teeb meem ntsuas kub: 1. "Qhov ntsuas kub uas tau piav qhia ntau dua nyob rau hauv lub system) Cause: Cov ntsuas kub tswj qhov teeb meem teeb tsa. Kev daws teeb meem: ① Thaum siv tus tswj hwm kub thiab ntsuas kub rau thawj zaug, Auto Tuning Ntsuas Kub kom phim cov Thermocouple kev ua tau zoo. Yog xav paub cov ntsiab lus, thov saib mus rau kev ua haujlwm ntawm kev sib raug ntsuas kub sib xws. ② Yog hais tias qhov kev txhaum tseem muaj feem ntxiv tom qab tov ①, lub zog ntawm rhaub rau 20 feeb thiab sim cov quab yuam thermoelective ntawm ob qho kawg ntawm lub thermocouple. Yog hais tias lub thermoelectromotive quab yuam tseem sawv, nws tuaj yeem txiav txim siab tias tsis muaj teeb meem nrog Thermocorouple Rhaub. Hloov cov xov hlau thermocouple thiab kub maub los ntsuas nyob rau hauv lem los kuaj qhov ua rau. Yog tias tus nqi voltage tsis txuas ntxiv mus, thov hu rau peb cov neeg muag khoom muag nyob rau lub sijhawm los hloov qhov kub txuas ntxiv mus tso tawm (lub tswb phem no tom qab ncav cuag ib qho kub). Cov lus piav qhia teeb meem: Qhov kub nyeem ntawm qhov ntsuas kub ntawm tus maub los ntsuas kub txuas ntxiv mus poob. Kev faib tawm: Cov xaim hluav taws xob txuas nrog tsis yog. Kev daws teeb meem: ① Txheeb xyuas seb puas hlau Thuj Hlau thiab Them Hlau Txuas txuas tau. Lub tsev tsim - hauv thermocouple xaim yog ntsuab) - tus ncej zoo ntawm peb lub tuam txhab cov nyiaj xaim hluav taws xob ntsuab) - tus ncej zoo ntawm cov ntsuas kub. ② Yog hais tias kev daws teeb meem ① txheeb xyuas kom raug thiab tsis muaj kev tshem tawm, thov khij cov rhaub kom zoo raws li cov khoom thib tsib dhau los - rhaub zoo soj ntsuam. Yog hais tias lub rhaub teeb meem yog tshem tawm, thov hloov cov ntsuas kub los txiav txim siab seb nws puas yog qhov teeb meem zoo ntawm tus ntsuas kub. Yog tias nws yog qhov teeb meem zoo ntawm lub rhaub, thov hu rau peb muag kom sai li sai tau rau cov khoom hloov mus rau ib qho kub thiab tom qab pib poob. Cov lus piav qhia teeb meem: Qhov kub nce siab thaum lub zog tig mus, tab sis pib poob ua ntej mus txog qhov ntsuas kub. Teeb meem kev faib tawm: Thermocouple cov teeb meem hlau: ① Hloov cov xov hlau thermocouple thiab tshawb xyuas cov teeb meem xaim hluav taws xob zoo. Yog tias nws yog qhov ntsuas hluav taws xob thermocouple zoo, thov hloov lub thermocouple hlau kom daws tau qhov teeb meem. ② Yog tias nws tsis yog Thermocouple cov teeb meem hlau zoo, thov khij cov rhaub kom zoo raws li cov khoom thib tsib dhau los - rhaub zoo soj ntsuam. Yog tias nws yog qhov teeb meem hluav taws xob muaj zog, thov hu rau peb muag rau kev hloov pauv. Yog tias nws tsis yog lub rhaub cov teeb meem zoo, thov hloov cov ntsuas kub:} Tsim teeb meem teeb meem daws teeb meem: ① Txheeb xyuas cov teeb meem ntsuas kub thiab tshawb xyuas qhov ntsuas kub. Tom qab teeb tsa nws kom raug, tus ntsuas kub yuav yuav kho tus kheej. ② Yog tias nws tseem tsis ua haujlwm ib txwm, thov tshawb xyuas seb puas muaj qhov teeb meem zoo nrog cov rhaub} Thaum lawv muaj teeb meem ntsuas qhov teeb meem. Cov lus piav qhia teeb meem: Ntau cov cua sov yog siv ib txhij, tab sis tsuas yog qee qhov ntawm lawv yog malfunctioning. Kev daws teeb meem: ① Txheeb xyuas tias qhov thermocouple lub chaw zoo thiab tsis zoo yog cov xaim hluav taws xob kom raug (tsaus ntuj ntsuab cim davhlau ya nyob twg yog qhov zoo). ② Yog tias cov xov hluav taws xob yog qhov tseeb, ntsuas qhov tsis kam ntawm cov hlau cua sov thiab thermocouple. Cov kev tawm tsam ntawm cov cua kub hlau tuaj yeem suav tau siv r=u² / p. Thermocouple kev tiv thaiv yuav tsum yog ntawm 0.3-1ω. Yog tias ob qho kev tiv thaiv yog qhov qub, lub zog rhaub rau 20 feeb thiab ntsuas lub zog thermoelectromotive (tef) hla lub thermocouple. Yog hais tias cov ntiv tes tseem sawv los, Thermocorouple Rhaub yog suav hais tias yog kev ua txhaum. Yog tias cov teeb meem zoo, thov hu rau peb tus neeg sawv cev muag rau cov rhaub hloov. ③ Yog hais tias kev daws teeb meem ② tsis daws qhov teeb meem, tab sis rhaub tseem ua haujlwm tsis zoo, hloov nws nrog ua haujlwm ua haujlwm thiab pom tias nws ua haujlwm tau zoo. Yog tias nws tseem tsis ua haujlwm zoo, xyuas cov xaim. Yog tias nws ua haujlwm tau zoo, thov hu rau peb cov khoom muag muag thiab xa rov qab cov khoom lag luam los ntawm peb cov teeb meem kev tshaj lij los ntawm Tes Tsho cov teeb meem. Cov lus piav qhia: Tom qab hloov cov xov hluav taws xob txuas, lub tes tsho xaim hluav taws xob feem ntau hlawv tawm thaum siv. Cause tes tsho tsis raug cov ntaub ntawv xaiv. Kev daws teeb meem: Qhov chaw xaim ntawm sab nraum qab ntawm rhaub yog qhov kub tau kub thaum siv. Siv lub tes tsho khi ua los ntawm cov khoom xws li tooj liab uas tsis yog cov cua sov-resistant tuaj yeem ua rau cov teeb meem no. Txoj kev ua kom yog yog siv lub npib tsib xee lossis hlau siv hlau siv.
