Nyocha nke usoro ịgbakọ ọkụ na igwe ịgbado ọkụ

Ngụkọta okpomọkụ ziri ezi dị mkpa na igwe ịgbado ọkụ nut iji hụ na njikwa okpomọkụ kwesịrị ekwesị n'oge usoro ịgbado ọkụ.Ịghọta okpomọkụ na-emepụta na ibufe dị oke mkpa maka ịnọgide na-arụ ọrụ kachasị mma, igbochi ikpo ọkụ, na ịhụ na welds dị elu.Isiokwu a na-enye nyocha nke usoro ngụkọ okpomọkụ nke a na-eji na igwe ịgbado ọkụ nut, na-akọwa mkpa ha na ngwa ha na-ekpebi oke okpomọkụ.

1. Ọgbọ Okpomọkụ: Ọgbọ ọkụ na igwe ịgbado ọkụ nut na-eme nke ọma n'ihi nguzogide eletrik na ebe weld.Enwere ike gbakọọ okpomọkụ a na-emepụta site na iji usoro: Okpomọkụ (Q) = I^2 * R * t Ebe:

• Q bụ okpomọkụ a na-emepụta (na joules ma ọ bụ watts)
• M bụ ịgbado ọkụ ugbu a (na amperes)
• R bụ nguzogide eletrik na ebe weld (na ohms)
• t bụ oge ịgbado ọkụ (na sekọnd)

2. Nfefe ọkụ: Ekwesịrị ijikwa ọkụ na-eme n'oge ịgbado ọkụ ka ọ ghara ikpo oke ọkụ.Mgbakọ mbufe ọkụ na-enyere aka ikpebi ihe mkpofu ọkụ chọrọ.Usoro mbufe ọkụ na-agụnye ịtụle ihe ndị dị ka ntụgharị, convection, na radieshon.Enwere ike ịkọwa ya dị ka: Q = Q_conduction + Q_convection + Q_radiation Ebe:

• Q_conduction na-anọchi anya okpomọkụ na-ebufe site na kọntaktị ozugbo n'etiti workpiece na electrodes.
• Q_convection na-ekwu maka ịnyefe okpomọkụ site na ikuku gbara ya gburugburu ma ọ bụ ihe na-ajụ oyi.
• Q_radiation na-ezo aka na nnyefe ọkụ site na radieshon electromagnetic.

3. Ihe ndị chọrọ jụrụ oyi: Iji nọgide na-arụ ọrụ nke ọma na okpomọkụ, ọnụego ikpo ọkụ ga-adabarịrị na ọnụego ọgbọ okpomọkụ.Enwere ike gbakọọ ihe jụrụ oyi site na iji usoro: Q_dissipation = Q_generation Ebe:

• Q_dissipation bụ ọnụego mgbasa ọkụ (na joules kwa nkeji ma ọ bụ watts)
• Q_generation bụ ọnụego ọgbọ okpomọkụ

Site n'ịgbakọ nke ọma okpomọkụ na-emepụta na ịghọta usoro nnyefe ọkụ, ndị na-arụ ọrụ nwere ike hụ na njikwa okpomọkụ dị mma na igwe ịgbado ọkụ nut.Nke a na-enyere aka igbochi ikpo ọkụ akụrụngwa, bulie ogo weld, ma kwalite arụmọrụ ịgbado ọkụ n'ozuzu ya.

Usoro mgbako ọkụ na-arụ ọrụ dị oke mkpa n'ịchọpụta ọgbọ okpomọkụ, nnyefe ọkụ, na ihe jụrụ oyi n'ime igwe ịgbado ọkụ nut.Site n'ịgbakọ nke ọma na ijikwa okpomọkụ, ndị na-arụ ọrụ nwere ike hụ na ọnọdụ ọrụ kachasị mma, gbochie ikpo oke ọkụ, ma nweta welds dị elu.Ịghọta usoro ndị a na-enyere ndị na-ahụ maka ọrụ aka ime mkpebi ziri ezi gbasara usoro ịgbado ọkụ, sistemu jụrụ oyi na ụzọ ikposa ọkụ.N'ikpeazụ, njikwa okpomọkụ kwesịrị ekwesị na-eduga n'ịrụ ọrụ ịgbado ọkụ, ogologo oge ndụ akụrụngwa, yana ịkwalite mmepụta n'ime usoro ịgbado ọkụ.
