Kev ntsuas thermocouple thiab ntsuas qhov ntsuas ntau
Ob hom khoom sib txawv ntawm cov neeg los sis semiconductors A thiab B sib txuas ua ke los tsim ib lub voj kev kaw. Thaum muaj qhov sib txawv ntawm qhov nruab nrab ntawm ob lub ntsiab lus siab 1 thiab 2 ntawm cov neeg sib tw A thiab B, ib qho kev sib txuas ntawm electromotive yog tsim los ntawm lawv, ua rau muaj qhov loj ntawm qhov tam sim no hauv lub voj, uas yog hu ua thermoelectric effect. Thermocouple yog kev siv cov nyhuv ua hauj lwm.
Xaiv lub thermocouple yuav ua raws li kev siv ntawm qhov kub thiab txias, qhov tseeb yuav tsum, kev siv cov cua, kev txiav txim siab ntawm kev ua tau ntawm qhov khoom, lub sijhawm teb thiab kev pab nyiaj txiag thiab lwm yam kev saib xyuas.
1, ntsuas kev ntsuas thiab qhov ntsuas kub ntau qhov kev xaiv Kev siv cov kub hauv qhov 1300 ~ 1800 ℃, qhov tseeb yuav tsum yog qhov siab, kev siv B-hom thermocouple; yuav tsum muaj tseeb yog tsis siab, qhov chaw tso cai rau kev siv tungsten rhenium thermocouple, siab dua 1800 ℃ Kev siv tungsten rhenium thermocouple; kev ntsuas kub ntawm 1000 ~ 1300 ℃ thiab qhov raug siab S-hom thermocouple thiab N-hom thermocouple; 1000 ℃ hauv qab siv dav K-hom thermocouple thiab N-hom thermocouple, tsawg dua 400 ℃ General siv E-hom thermocouple; 250 ℃ thiab ntsuas kub tsis zoo feem ntau yog siv T-hom galvanic, tsawg T-hom thermocouple stability thiab siab dua.
2, kev siv ntawm qhov chaw S-Type, B-type, K-type thermocouple haum rau oxidation muaj zog thiab tsis muaj zog siv cov cua, J-hom thiab T-type thermocouple haum rau oxidation tsis muaj zog thiab txo cov cua, yog tias kev siv cua nrig sib piv Kev tiv thaiv zoo tiv thaiv tube, qhov yuav tsum tau ntawm cov cua tsis yog nruj heev.
3, kev xaiv ntawm cov kav ntev thiab thermal teb ntawm lub zog thermocouple yog qhov zoo, tiam sis cov lus teb yog qeeb qeeb, rau lub peev kub ntawm lub thermocouple, qhov lus teb qeeb, ntsuas cov gradient ntawm qhov kub thiab txias, Txawv qhov txawv. Yuav tsum muaj sij hawm sai sai thiab yuav tsum muaj ib cov teeb meem ntawm kev ua kom ntev, xaiv armor tseem tsim nyog.
4, qhov khoom ntawm qhov khoom thiab lub xeev ntawm qhov kev xaiv ntawm thermocouple
Tsiv khoom, khoom khoom vibration, kub siab lub hauv siab uas yuav tsum tau ua kom siab zog, tshuaj muaj kuab paug, qhov chaw yuav tsum muaj lub raj tiv thaiv, hluav taws xob cuam tshuam ntawm qhov yuav tsum tau muaj dua rwb thaiv tsev
