Olee otú ịgbanwe ugbu a nke rotor akpaka akara ntụpọ ịgbado ọkụ igwe?
The rotor akpaka ahịrị ntụpọ welder na mbụ onwem na AC njikwa na AC ntụpọ welder, ma ejighị n'aka ugbu a nke AC ntụpọ welder na nsogbu nke mebere ịgbado ọkụ mere ka ọ na-anọchi ya intermediate ugboro inverter DC njikwa, intermediate ugboro inverter, na a ntụpọ welder. N'isiokwu a, anyị ga-atụle ụzọ dị iche iche nke imezi ugbu a nke rotor akpaka waya ntụpọ welder:
1. Njikwa ọnọdụ ike mgbe niile: Iji ọnọdụ ike mgbe niile Q = UI nwere ike zere ịrị elu nke electrode resistivity na okpomọkụ mgbe ị na-eji ọnọdụ dị ugbu a mgbe niile, ma gbochie thermal Q = I2Rt ebili. Site n'iji ụfọdụ ọnọdụ ike Q=UI, okpomọkụ nwere ike itule.
2. Ntụle voltaji nke eriri akpaaka abụọ-rotor: a ga-eme nha voltaji dị ka o kwere mee na mkpanaka ndị dị mma na nke na-adịghị mma. Isi ihe bụ ijikwa uru voltaji n'etiti oghere ndị dị mma na nke na-adịghị mma, ọ bụghị voltaji nke sekit dum.
3. Gbanwee site na nkwụsị nke 1-pulse na nkwụsị 2-pulse ma ọ bụ 3-pulse (mkpokọta oge nkwụsị na-agbanwe agbanwe), ma belata uru ike (ma ọ bụ uru dị ugbu a) na nke kacha nta. Ọ bụrụ na eji mwepu pulsed, ọ ga-adị mkpa ịbawanye uru ike iji nweta okpomọkụ ịgbado ọkụ achọrọ. Ọ bụrụ na a na-eji mwepu okpukpu abụọ (ọnụahịa mwepu nke mbụ na-adị ala, ma ọ bụrụ na ọ dị elu ka ọ dị elu), uru ike (ma ọ bụ uru dị ugbu a) nwere ike belata nke ukwuu maka ịgbado ọkụ. Mbelata uru ike (ma ọ bụ uru dị ugbu a) na-ebute mbelata eyiri electrode yana nkwụsi ike ịgbado ọkụ. Q=I2Rt pụtara na mkpokọta okpomọkụ na-emetụtawanye uru nke ugbu a. Ya mere, mgbe ị na-edozi paramita, belata uru dị ugbu a (ma ọ bụ uru ike) na nke kacha nta.
4. Dochie tungsten electrode na nko n'okpuru welder ntụpọ na electrode na-adịghị mma, n'ihi na nke ugbu a na-esi na nko ahụ gaa na tungsten electrode, na-eme ka "electron ije", na-eme ka obere ígwè ígwè na-eruba na electrode, na-eme ka ọ dị ọcha na ike gwụrụ. "Electronic motion" pụtara na nfe nke metal valence electrons na-ebute mmegharị nke ahụ mmiri nwere atom ọla.
Dị ka usoro a dị n'elu si dị, enwere ike ịmecha ihe ndozi nke rotor akpaka waya ntụpọ igwe ịgbado ọkụ. Isiokwu a na-achọ ịghọta nke ọma ojiji electromechanical nke rotor akpaka waya ntụpọ welders ka mma mmepụta arụmọrụ na-azọpụta ike. Tụkwasị na nke ahụ, a ga-ejikọta mmezigharị oge niile n'ime ọrụ nke ahịrị mmepụta rotor na-akpaghị aka. Nke a na-enye aka na ogologo ndụ ya na arụmọrụ ya.
