Lub nplaim taws kub ntawm lub teeb yog dab tsi?
Cov nplaim taws kub ntawm lub teeb sib txawv nyob ntawm nws hom thiab cov roj siv, feem ntau yog li ntawm 300℃txog 3200 degree. Tshwj xeeb, torches tuaj yeem muab faib ua peb pawg hauv qab no:
Classification los ntawm Torch Type
Handheld Torches: Cov qauv feem ntau tsim cov nplaim taws kub ntawm 1200℃thiab 1300 degree, tsis tshua muaj siab tshaj 1400 degree. Cov hluav taws xob no feem ntau siv rau me me - vuam vuam, kho cua sov, lossis kev tswj cov nroj tsuag ua liaj ua teb.
Propulsion System Torches:
Phom phom-Driven Systems (piv txwv li, MFB9- hom hluav taws tua hluav taws): Qhov kub thiab txias tuaj yeem tshaj 300℃; cov no feem ntau yog siv rau kev tso tawm sai lossis luv luv, ua haujlwm kub.
Cov pa roj carbon dioxide-Driven Systems (piv txwv li, MFB10- hom): Ua haujlwm kub li ntawm kwv yees li 100℃txog 150℃; cov no siv qhov nthuav dav ntawm qis-kub roj kom ua tiav cov dej txias lossis tua hluav taws.
Liquid Fuel Combustion Systems (Industrial Torches): Cov tub ntxhais kub siab tshaj 1000 degree, ua rau lawv tsim nyog rau kev siv xws li hlau txiav thiab smelting.
Kev faib tawm los ntawm Hom Roj
Gaseous Fuel Torch:
Txheem LPG Teeb: Kwv yees li 900 degree; feem ntau yog siv rau kev kho vaj tse hauv tsev lossis kev ua haujlwm cua sov yooj yim.
Butane Torches: tuaj yeem ncav cuag 1500 degree; portable heev thiab haum rau cov hniav nyiaj hniav kub ua los yog sab nraum zoov ua noj ua haus.
Propane Torches: Kwv yees li 1260℃txog 1300 degree; siv nyob rau hauv kev lag luam chaw rau vuam los yog siv cov cua sov-shrink tubing.
Oxygen-Acetylene Torches (Oxy- acetylene nplaim): Kub tuaj yeem ncav cuag 3200 degree, ua rau lawv yog ib qho cuab yeej siv tau zoo tshaj plaws rau kev txiav thiab vuam.
Liquid Fuel Torch:
Gasoline Blowtorches: Cov nplaim hluav taws kub muaj li ntawm 900℃txog 1000 degree; nquag siv rau ntawm qhov chaw tsim kho lossis kho txoj kev.
Mixed LPG Combustion: Hlawv ntawm kwv yees li 1000℃hauv huab cua puag ncig; thaum sib xyaw nrog cov pa ntshiab huv, qhov kub tuaj yeem ncav cuag li 2000 degree, ua rau lawv haum rau cov ntawv thov uas yuav tsum muaj qhov kub siab tshaj -.
Cov Ntsiab Lus cuam tshuam
Cov nplaim hluav taws kub yog feem ntau txiav txim siab los ntawm hom roj, ntim ntawm cov pa oxygen nkag, thiab kev ua kom combustion efficiency. Piv txwv li, oxy- nplaim taws acetylene ua tiav qhov kub thiab txias siab dua li cov qauv LPG teeb hluav taws xob vim tias acetylene reacts tag nrho nrog cov pa ntshiab; conversely, carbon dioxide-tsav tshuab ua kom kub qis dua combustion-raws li torches, raws li lawv cia siab rau qhov expansion ntawm tsawg-kub roj es tsis combustion. Hauv kev siv tswv yim, hom tsim nyog yuav tsum raug xaiv raws li qhov xwm txheej tshwj xeeb: rau kev ua haujlwm siab - kub, oxyacetylene nplaim lossis propane teeb yog qhov kev xaiv zoo dua; rau qis-kub txias lossis hluav taws tua hluav taws, siv cov pa roj carbon dioxide- tsav.
