Zotsatira za Kukaniza Kuwotcha mu Makina Owotcherera a Medium Frequency Inverter Spot

Kukaniza kumatenga gawo lalikulu pakuwotcha kwa makina owotcherera apakati pafupipafupi inverter spot.Nkhaniyi ikufotokoza momwe kutentha kumakhudzidwira ndi momwe zimakhudzira ntchito zowotcherera.

Kutentha kwa Ohmic:
Kutentha kwa Ohmic ndiye njira yoyamba yomwe kukana kumakhudza kutentha kwa kuwotcherera pamalo.Mphamvu yamagetsi ikadutsa pa kondakitala, monga chogwirira ntchito, kutentha kumapangidwa chifukwa cha kukana komwe kumakumana ndi pano.Kuchuluka kwa kutentha komwe kumapangidwa kumagwirizana mwachindunji ndi kukana kwa conductor.
Kutaya Mphamvu:
Mphamvu zomwe zimatayidwa muzogwiritsira ntchito zimatsimikiziridwa ndi zomwe zili pamtunda wamakono (I ^ 2) ndi kukana (R).Chifukwa chake, kuchuluka kwa kukana kumabweretsa kuwonongeka kwakukulu kwamagetsi, zomwe zimapangitsa kutentha kwakukulu kwa chogwirira ntchito panthawi yowotcherera.
Katundu:
Kukaniza kwa chinthu kumakhudzidwa ndi mphamvu zake zamagetsi.Zida zokhala ndi resistivity yapamwamba, monga ma aloyi kapena zitsulo zosapanga dzimbiri, zimawonetsa kukana kwambiri ndipo, chifukwa chake, zimawotcha kwambiri panthawi yowotcherera.
Kukula kwa Workpiece ndi Geometry:
Kukula ndi geometry ya chogwiriracho chimakhudzanso kukana ndi kutentha.Zopangira zazikulu nthawi zambiri zimakhala zolimba kwambiri chifukwa cha kuchuluka kwake, zomwe zimapangitsa kuti pakhale kutentha kwakukulu panthawi yowotcherera.
Contact Resistance:
Kukana kukhudzana pakati pa ma electrode ndi workpiece kungakhudzenso kutentha.Kusalumikizana bwino kwa ma elekitirodi kapena kuipitsidwa kwapamtunda kumatha kuyambitsa kukana kwina komwe kumalumikizidwa, zomwe zimapangitsa kuti pakhale zotentha zamtundu wina komanso kusagwirizana komwe kungachitike pamtundu wa weld.
Resistance imagwira ntchito yofunika kwambiri pakuwotcha kwa makina owotcherera apakati pafupipafupi inverter spot.Imakhudza mwachindunji kuchuluka kwa kutentha komwe kumapangidwa mu workpiece panthawi yowotcherera, ndi zinthu monga zinthu zakuthupi, kukula kwa workpiece, geometry, ndi kukana kukhudzana komwe kumathandizira pakutentha konse.Kumvetsetsa kukhudzika kwa kukana pakuwotchera ndikofunikira kuti muwongolere magawo azowotcherera, kuwonetsetsa kugawa koyenera kwa kutentha, ndikupeza ma welds odalirika komanso apamwamba kwambiri.Poyang'anira ndikuyang'anira kuchuluka kwa kukana, ogwiritsira ntchito amatha kuyendetsa bwino ntchito yowotchera ndikupereka zotsatira zofananira pakugwiritsa ntchito kwawotcherera.
