MFDC Welding vs AC Welding: Ndani Amabwera Pamwamba?

kuwotcherera kwa Mid-Frequency direct current (MFDC) ndi kuwotcherera kwa alternating current (AC) ndi njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri, iliyonse ili ndi mawonekedwe ake.M'nkhaniyi, tiwunikira limodzi kuti ndi ndani yemwe ali ndi dzanja lapamwamba: kuwotcherera kwa MFDC kapena kuwotcherera kwa AC?

Mfundo Zogwirira Ntchito:

MFDC/Inverter Welding Machine:

Choyamba, magetsi a magawo atatu a AC amadutsa muzokonzanso kuti zisefe.

Kachiwiri, ma switch a IGBT amasintha zomwe zilipo kuti zikhale zapakati pa 1000 Hz ndikuzitumiza ku chosinthira chowotcherera.

Pomaliza, ma diode owongolera mphamvu kwambiri amatulutsa mphamvu zowotcherera ngati stable current (DC).

Makina Owotcherera a AC:

Mphamvu yamagetsi ndi AC, yomwe, ikadutsa pamagetsi, imalowa m'dera lalikulu ndi dera lolamulira.

Transformer imatsitsa mphamvu yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yocheperako, yoyenera kuwotcherera.AC panopa alternates zabwino ndi zoipa, kutulutsa kutentha pamene akudutsa kuwotcherera ndodo ndi workpiece, potero kusungunula zinthu kuwotcherera ndi kukwaniritsa kuwotcherera.

Ubwino wa MFDC Welding pa AC Welding:

Kukhazikika Kwambiri:

MFDC kuwotchereraimadziwika padziko lonse lapansi ngati imodzi mwazinthu zowotcherera kwambiri, zomwe zimapangitsa bata pakuwotcherera.Njira zake zowotcherera mwaubwenzi komanso kusinthasintha kwamitundu yachiwiri komwe kumakhalapo nthawi zonse, kumapereka chiyembekezo chochulukirapo kuposa kuwotcherera kwa AC.

Gwero lamagetsi la MFDC limatulutsa mawonekedwe ocheperako, kupewa nsonga zomwe zikuchitika komanso kuchepetsa kuwotcherera.

Kusintha kwa MFDC kuwotcherera kwaposachedwa kumachitika pamlingo wa 1000 pa sekondi iliyonse, kukwaniritsa kulondola kwamlingo wa millisecond, komwe kumakhala kolondola ka 20 kuposa makina owotcherera achikhalidwe a AC.

Kuwotcherera kwa MFDC sikukhudzidwa ndi mawonekedwe ndi zinthu za workpiece, kuchotsa zotayika zochititsa chidwi.

Mwachangu:

Makina owotcherera a MFDC amapeza mphamvu yowotcherera yopitilira 98%, pomwe makina a AC ali mozungulira 60%, zomwe zikuwonetsa kuchita bwino kwambiri pakuwotcherera kwa MFDC.

Mitengo Yotsika:

Chifukwa chakuchulukirachulukira koyamba kwa kuwotcherera pakali pano, nthawi yeniyeni yowotcherera imafupikitsidwa ndi kupitilira 20%, zomwe zimachepetsa kwambiri kufunikira kwa kuwotcherera.

Zofunikira pamagetsi a fakitale ndizotsika, pafupifupi 2/3 ya makina owotcherera a AC, ndipo ngakhale kusinthasintha kwamagetsi amagetsi, makina owotcherera a MFDC amathabe kuwongolera ndendende.

Chifukwa chake, kugwiritsa ntchito mphamvu kwa makina owotcherera a MFDC kumachepetsedwa kwambiri, ndikupulumutsa mphamvu zopitilira 40%.Kuonjezera apo, kugwiritsa ntchito magulu atatu a katundu woyenerera kumatsimikizira kuti palibe gulu lomwe liri lodzaza, kukwaniritsa zofunikira zotetezera mphamvu zachuma.

Opepuka:

Poyerekeza ndi makina owotcherera a AC, thiransifoma yowotcherera ya makina a MFDC ndiyopepuka kwambiri, kupangitsa kuti zidazo zikhale zosavuta komanso zosavuta.Imalemera gawo limodzi mwa magawo atatu a kulemera kwa AC thiransifoma ndi voliyumu yake, yoyenera makina owotcherera a robot.

Wosamalira zachilengedwe:

Kuthetsa kuipitsidwa kwa magetsi, kuwotcherera kwa MFDC ndi njira yowotcherera yobiriwira yomwe sikutanthauza magetsi osiyana ndipo ingagwiritsidwe ntchito limodzi ndi makina owongolera ma robot.

Mwachidule, kuwotcherera kwa MFDC kumaposa kuwotcherera kwa AC potengera kukhazikika kwa kuwotcherera, mtundu, magwiridwe antchito, kupulumutsa mphamvu, zida zopepuka, komanso kuchepa kwamagetsi pamagetsi.

Agera imapereka makina owotcherera apakati pafupipafupi, okhala ndiukadaulo wazowotcherera wa MFDC wofika pamlingo wapamwamba wapadziko lonse lapansi.The pazipita yochepa dera panopa kufika 250,000 amperes, chimagwiritsidwa ntchito zitsulo zosiyanasiyana aloyi, zitsulo mkulu-mphamvu, zitsulo otentha kupanga, ndi zotayidwa aloyi malo kuwotcherera njira, kupereka zida mkulu-mapeto ndi ntchito odalirika makampani ambiri odziwika padziko lonse Fortune 500. .
