Nyob ntawd yog _ hom plasma arc txiav txheej txheem. Koj nyuam qhuav kawm 15 nqe lus!
Yog li ntawd, dab tsi tam sim no siv plasma arc txiav?
Ib tug precision ntshav arc yog kwv yees li 40-50K amps ib square inch. Ntau cov pa roj xws li oxygen, huab cua purity siab, nitrogen, thiab hydrogen / argon / nitrogen sib tov yog siv raws li cov ntshav ntshav gas rau kev ua tau zoo tshaj plaws ntawm ntau yam khoom siv hluav taws xob.
Qhov thib ob, plasma arc txiav yog dab tsi? Cov plasma arc txiav txheej txheem yog txheej txheem thermal-raws li fabrication uas siv lub constricted, pauv ntshav arc rau txiav los ntawm ntau yam hlau, nrog rau cov qauv hlau, hlau alloy, aluminium, thiab tooj liab.
Ib sab saum toj no, ob hom plasma arc txiav txheej txheem yog dab tsi?
Plasma arcs yog tsim los ntawm cov pa roj ob daim ntawv ib qho yog laminar (tsis tshua muaj siab thiab tsis tshua muaj ntws) thiab qhov thib ob yog turbulent flow (siab siab thiab siab ntws).
Vim li cas plasma arc txiav feem ntau siv?
Vim lub siab ceev thiab precision ntawm lub txiav ntawm tus nqi qis, plasma txiav yog dav siv los ntawm kev lag luam loj CNC daim ntaub ntawv mus rau cov tuam txhab nyiam me me uas cov ntaub ntawv tom qab siv rau vuam. Plasma txiav - Cov pa hluav taws xob nrog qhov kub txog li 30,000 ° C ua plasma txiav thiaj li tshwj xeeb.
