Dub zaj duab xis ntawm hluav taws xob cua sov raj caij

Cov xim pleev xim, tseem hu ua zaj duab xis dub, tau tsim nyob rau xyoo 1950s thiab tuaj yeem siv los ua hluav taws xob cua sov tom qab tau txau rau ntawm qhov chaw insulating. Muaj ntau yam kev siv cov txheej txheem conductive, tab sis tsawg daim ntawv thov raws li cov khoom siv hluav taws xob. Cov xim pleev xim muaj qhov zoo ntawm cov cua sov saum npoo, qhov loj ntawm cov cua kub dissipation, thiab kev ua haujlwm zoo seismic. Qhov tsis zoo ntawm cov txheej txheej conductive yog tias nws yooj yim rau tev tawm cov txheej kub, thiab nws tsuas yog siv tau rau cua sov hauv qab 200 degree.

Thermistor ntawm hluav taws xob cua sov tube caij

Lub npe tag nrho ntawm PTC yog qhov zoo kub coefficient, los yog thermistor, uas yog cov khoom cua kub sib xyaw sintered los ntawm cov khoom siv hluav taws xob. PTC cov khoom cua sov yog ib hom cua sov uas txwv los ntawm Curie kub. Nws tsuas yog siv tau thaum kub hauv qab 350 degree. Haum rau txhua yam ntawm cov khoom siv hluav taws xob tsawg, qhov kub thiab txias. PTC cua sov lub caij muaj qhov zoo ntawm cov cua sov uas tsis muaj nplaim taws, thiab cov cua sov ua haujlwm siab li 70 feem pua.

Qhov tsis zoo ntawm kev ua haujlwm tsis zoo ntawm PTC cov khoom siv hluav taws xob tsis tuaj yeem raug txiav thiab siv tsis tau, tshwj xeeb tshaj yog, Curie kub txwv ntawm PTC cov khoom siv hluav taws xob tsis tuaj yeem siv rau cov cua sov siab tshaj 350 degree, thiab daim ntawv thov ntawm PTC cov khoom cua sov hauv cov khoom siv tiag tiag thiab lub neej teb tsuas tuaj yeem txwv tsis pub muaj cua sov.

Disadvantages ntawm hluav taws xob cua sov tube Cheebtsam

Qhov tsis zoo ntawm cov hlau yog nws lub zog hloov pauv qis. Cov txheej txheem cua sov yog nrog rau lub teeb-emitting txheej txheem, yog li lub zog hloov pauv tuaj yeem ncav cuag 60 feem pua ​​​​rau 70 feem pua.

Hluav taws xob cua sov tube caij hlau

Hluav taws xob cua sov hlau yog ib hom cua sov uas tshwm sim thaum ntxov, thiab nws yog lub hauv paus ntsiab lus ua hauj lwm ntawm hluav taws xob cua sov kom paub lub zog hloov dua siab tshiab. Txawm hais tias cov tsoos hluav taws xob cua sov hlau hluav taws xob cov khoom siv hluav taws xob tsis tau hloov pauv, cov cua sov tam sim no tseem siv dav hauv ntau qhov chaw, tshwj xeeb tshaj yog kev tsim khoom thiab chaw soj nstuam. Nyob rau hauv xyoo tas los no, hlau-chromium-aluminium thiab npib tsib xee-chromium alloys tau dav siv nyob rau hauv cua sov xov hlau, thiab qhov kub ntawm hlau-chromium-aluminium alloys tau mus txog 1400 degree. Cov hlua hluav taws xob yog ua raws li cov hlua hluav taws xob, hluav taws xob hluav taws xob, thiab cov khoom cua sov tsim nyob rau hauv xyoo tas los no, tab sis lawv cov ntsiab lus tseem yog hluav taws xob, thiab lawv txoj cai tsis tuaj yeem sib cais los ntawm hluav taws xob. Cov cua kub cua sov thiab qhov zoo ntawm cov cua kub cua sov, cov cuab yeej paub tab, yooj yim los tsim thiab siv, txhawb ntau yam khoom siv hluav taws xob.
