Hluav taws xob rauv hlau feem ntau muaj cov hlau tsis muaj zog

Hluav taws xob rauv hlau feem ntau muaj cov hlau tsis muaj zog

High resistance alloy, nickel chromium hlau tuaj yeem ncav cuag 1250 degrees, thiab hlau chromium txhuas hlau tuaj yeem ncav cuag 1400 degrees.

Ib qho tseem ceeb parameter ntawm hluav taws xob cua sov hlau yog lub zog nto. Yog tias qhov kev tiv thaiv siab dhau lawm, lub zog saum npoo yuav nce ntxiv thaum siv qee qhov tam sim no. Yog li ntawd, rau cov khoom siv hluav taws xob tsawg, txoj kab uas hla me me tam sim no raug xaiv, tab sis qhov loj ntawm qhov tam sim no nyob ntawm qhov loj ntawm qhov tsis kam, thiab qhov ntev thiab txoj kab uas hla ntawm cov cua sov hlau yog xam.

Tom qab hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob tawm, txuas nws thiab siv txuas ntxiv mus. Vim yog kev sib cuag tsis zoo, kev tiv thaiv siab, thiab kub kub ntawm qhov sib koom ua ke, nws muaj peev xwm hlawv tawm ntau dua. Ntau qhov kev sib cuag ntawm ob lub tshuab hluav taws xob hauv hluav taws xob tuaj yeem ua rau thaj chaw sib cuag thiab txo qhov kub thiab txias. Hlawv lossis txiav tawm ib daim, qhov ntev yog luv dua ua ntej, qhov kev tiv thaiv me dua ua ntej, thiab lub zog yuav nce raws li U2/R=P. Nws yog ib qho tseem ceeb uas yuav tau xyuam xim rau kev siv nyab xeeb. Nws muaj qhov tsis txaus ntseeg, kev ua haujlwm siab thiab kev txuag hluav taws xob (kev txuag hluav taws xob ntawm 40%, lub sijhawm thermal teb tsawg dua 15S), thermal inertia me me, qhov kub hloov pauv dav dav (kho tau los ntawm 100 degree mus rau 520 degree), qhov kub hloov kho qhov tseeb, ruaj khov hluav taws xob. kev ua tau zoo (kub txias tsis kam hloov pauv piv tsawg dua 1.7, lub zog sib txawv tsawg dua ± 10%), thiab qhov zoo tshaj plaws piv rau cov khoom siv hluav taws xob hluav taws xob cua sov yog tias lawv tuaj yeem ua rau ntau qhov hluav taws xob thiab hluav taws xob, nrog rau kev tiv thaiv hluav taws xob ntau dua. ; Rau qee qhov, nws tuaj yeem hloov pauv cov khoom siv hluav taws xob hluav taws xob uas muaj hluav taws xob tsis muaj cua sov, nrog rau qhov zoo ntawm kev nyab xeeb thiab ua haujlwm ntev (cov rwb thaiv tsev tiv thaiv ntau dua 100M Ω, kev pabcuam lub neej ntau dua 3000 teev), ua tiav cov lus qhia (qhov tsawg kawg nkaus txoj kab uas hla tuaj yeem ua tau. 2.5 hli).
