Mid-frequency direct tam sim no (MFDC) welding thiab alternating tam sim no (AC) vuam yog ob feem ntau siv vuam txheej txheem, txhua tus muaj nws tus yam ntxwv.Nyob rau hauv tsab xov xwm no, peb yuav soj ntsuam ua ke uas ib tug muaj lub sab sauv tes: MFDC vuam los yog AC vuam?
Cov Cai Ua Haujlwm:
MFDC / Inverter Vuam Tshuab:
Ua ntej, peb-theem AC voltage dhau los ntawm rectifiers rau lim.
Qhov thib ob, IGBT hloov pauv hloov tam sim no rau hauv nruab nrab zaus tam sim no ntawm 1000 Hz thiab xa mus rau lub vuam transformer.
Thaum kawg, high-power rectifier diodes tso tawm cov vuam tam sim no raws li qhov ruaj khov tam sim no (DC).
AC Vuam Tshuab:
Lub zog tawm tswv yim yog AC, uas, tom qab dhau los ntawm lub hwj chim hloov, nkag mus rau hauv lub ntsiab Circuit Court thiab tswj Circuit Court.
Lub transformer nqis los ntawm high-voltage AC mus rau qhov tsawg-voltage AC haum rau vuam.AC tam sim no hloov ntawm qhov zoo thiab qhov tsis zoo, ua kom muaj cua sov thaum nws dhau los ntawm vuam pas nrig thiab cov khoom ua haujlwm, yog li melting cov khoom siv vuam thiab ua tiav vuam.
Qhov zoo ntawm MFDC Vuam dua AC Vuam:
Kev ruaj ntseg siab:
MFDC vuamtau lees paub thoob ntiaj teb tias yog ib qho ntawm cov khoom siv high-end welding, txhim khu kev ruaj ntseg thaum vuam.Nws cov txheej txheem vuam tus phooj ywg tsis zoo thiab kev hloov pauv dav dav ntawm theem nrab tam sim no yeej tswj tau qhov tam sim no, muab qhov kev cia siab dav dua li AC vuam.
MFDC lub zog hluav taws xob tso tawm qhov tsawg kawg nkaus waveform, zam qhov cuam tshuam rau qhov siab tshaj plaws tam sim no thiab txo qis splashing thaum vuam.
Kev hloov ntawm MFDC vuam tam sim no tshwm sim ntawm tus nqi ntawm 1000 zaug ib ob, ua tiav millisecond-theem precision, uas yog tshaj 20 npaug ntau dua li cov tsoos AC vuam tshuab.
MFDC vuam tsis cuam tshuam los ntawm cov duab thiab cov khoom ntawm lub workpiece, tshem tawm inductive poob.
Kev ua haujlwm siab:
MFDC vuam tshuab ua tiav qhov vuam fais fab ntawm ntau dua 98%, thaum lub tshuab AC nyob ib ncig ntawm 60%, qhia tau tias kev ua haujlwm zoo hauv MFDC vuam.
Cov Nqi Ua Haujlwm Tsawg:
Vim tias qhov nce ntawm qhov pib ntawm vuam tam sim no, qhov tseeb vuam lub sij hawm luv luv los ntawm ntau tshaj 20%, txo qhov kev thov rau vuam siab.
Cov kev cai rau lub Hoobkas fais fab mov yog qis dua, tsuas yog kwv yees li 2/3 ntawm AC vuam tshuab, thiab txawm tias muaj qhov hloov pauv ntawm lub zog hluav taws xob, MFDC vuam tshuab tseem tuaj yeem tswj cov vuam tam sim no.
Yog li ntawd, kev siv hluav taws xob ntawm MFDC vuam tshuab tau txo qis, ua tiav kev txuag hluav taws xob ntau dua 40%.Tsis tas li ntawd, siv peb pawg ntawm cov khoom sib npaug ua kom ntseeg tau tias tsis muaj pab pawg muaj ntau dhau, ua tau raws li qhov yuav tsum tau muaj rau kev txuag nyiaj txiag.
Lub teeb:
Piv rau AC vuam tshuab, vuam transformer ntawm MFDC cov cav tov yog qhov sib dua, ua rau cov cuab yeej siv tau yooj yim thiab yooj yim.Nws hnyav tsuas yog ib feem peb ntawm AC transformer qhov hnyav thiab ntim, haum rau cov neeg hlau vuam tshuab.
Environmentally Friendly:
Tshem tawm cov pa phem rau cov khoom siv hluav taws xob, MFDC welding yog txoj kev vuam ntsuab uas tsis tas yuav muaj lub zog sib cais thiab tuaj yeem siv ua ke nrog cov neeg hlau vuam fixture tswj tshuab.
Nyob rau hauv cov ntsiab lus, MFDC vuam tshaj AC vuam nyob rau hauv cov nqe lus ntawm vuam stability, zoo, efficiency, lub zog txuag, lub teeb yuag khoom, thiab txo hwj chim yuav tsum tau rau lub hwj chim mov system.
Agera muaj ntau yam ntawm nruab nrab zaus qhov chaw vuam tshuab, nrog MFDC tsis kam vuam tshuab mus txog qib siab thoob ntiaj teb.Qhov siab tshaj plaws luv luv tam sim no ncav cuag 250,000 amperes, dav siv nyob rau hauv ntau yam hlau alloys, high-strength steels, kub-tsim steels, thiab txhuas alloy qhov chaw vuam txheej txheem, muab high-end khoom thiab txhim khu kev qha cov kev pab cuam rau ntau lub ntiaj teb no renowned Fortune 500 tuam txhab uas muag .
