Kuwunika kwa Resistance Kuwonjezeka kwa Makhalidwe mu Makina Owotcherera a Medium Frequency Inverter Spot

Kuchuluka kwa kukaniza ndi chinthu chodziwika bwino chomwe chimawonedwa pamakina owotcherera ma frequency inverter spot.Nkhaniyi ikufuna kuwunika momwe kukana kuchulukira ndi zotsatira zake pakuwotcherera malo.

Kuwotcha:
Chimodzi mwazinthu zazikulu zomwe zimathandizira kuti kukana kuchuluke ndikuwotchera kwa malo.Pamene mphamvu yapamwamba imadutsa pa workpiece, kutentha kumapangidwa chifukwa cha kukana magetsi.Kutentha kumeneku kumapangitsa kutentha kwa chogwirira ntchito kukwera, zomwe zimapangitsa kuti ziwonjezeke.
Katundu:
Kuwonjezeka kukana kungathenso kukhudzidwa ndi zinthu zakuthupi za workpiece.Zida zina zimawonetsa kuwonjezeka kwakukulu kwa kukana poyerekeza ndi zina chifukwa cha chibadwa chawo chamagetsi ndi matenthedwe.Mwachitsanzo, zida zokhala ndi ma conductivity otsika kapena ma coefficients owonjezera amafuta amatha kukhala ndi chiwonjezeko chachikulu chokana.
Contact Resistance:
Chinthu chinanso chomwe chingathandize kuti kukana kuchuluke ndi kukana kukhudzana pakati pa ma electrode ndi workpiece.Kusalumikizana bwino ndi ma elekitirodi kapena kuipitsidwa kwapamtunda kumatha kupangitsa kuti pakhale kukana kwambiri, zomwe zimapangitsa kuti pakhale kukana kwathunthu pakuwotcherera.
Electrode Wear:
M'kupita kwa nthawi, ma electrode mumakina owotcherera amatha kutha ndikuwonongeka.Pamene ma elekitirodi akusokonekera, malo awo olumikizana ndi chogwirira ntchito amachepa, zomwe zimapangitsa kuti pakhale kukana kukhudzana ndi kukana kwathunthu pakuwotcherera.
Oxidation ndi kuipitsidwa:
Kukhalapo kwa makutidwe ndi okosijeni kapena kuipitsidwa pamwamba pa workpiece kungayambitsenso kukana.Malo okhala ndi okosijeni kapena oipitsidwa amakhala ndi kukana kwamagetsi kwambiri, zomwe zimakhudza kuyenda kwapano ndipo kumapangitsa kuti pakhale kuwonjezeka kwamphamvu pakuwotcherera.
Kuchuluka kwa kukaniza ndi chinthu chodziwika bwino pamakina owotcherera ma frequency inverter spot, omwe amayamba chifukwa cha kutentha, katundu wakuthupi, kukana kukhudzana, kuvala ma elekitirodi, ndi makutidwe ndi okosijeni kapena kuipitsidwa.Kumvetsetsa izi ndikofunikira pakuwongolera njira zowotcherera pamalo ndikuwonetsetsa kuti ma welds okhazikika komanso odalirika.Poyang'anira ndikuthana ndi zomwe zimapangitsa kuti kukana kuchuluke, ogwiritsira ntchito amatha kusunga zowotcherera zomwe akufuna ndikukwaniritsa ma welds apamwamba kwambiri pakugwiritsa ntchito kwawo.
