Akụkụ Excavator EC55 mkpọchi nchekwa pilot na-atụgharị solenoid valvụ eriri igwe

Ọrụ nke eriri igwe

1. Mmetụta na-egbochi ugbu a: Ike electromotive nke na-eme onwe ya na eriri inductor na-eme ka mgbanwe dị ugbu a na eriri igwe. Ihe mkpuchi inductance nwere mmetụta mgbochi na AC ugbu a, na oke mmetụta mgbochi a na-akpọ inductance xl, na unit bụ ohm. Mmekọrịta ya na inductance L na AC ugboro F bụ xl=2πfl. Enwere ike kewaa inductors ka ọ bụrụ eriri nkpakọ nke na-eme ihe dị elu na mkpuchi mkpuchi obere ugboro.

2. Ntugharị na nhọrọ ugboro ugboro: enwere ike ịmepụta sekit lc site na ijikọ eriri inductance na capacitor n'otu aka ahụ. Ya bụ, eke oscillation ugboro f0 nke sekit bụ hà ugboro f nke na-abụghị alternating mgbaàmà, otú inductive reactance na capacitive reactance nke sekit bụkwa hà nhata, ya mere, electromagnetic ume oscillates azụ na-apụta na inductance na. capacitance, nke bụ resonance onu nke sekit lc. Na resonance, ndị inductive reactance na capacitive reactance nke sekit bụ Ẹkot na-emegide. Inductance nke ngụkọta ugbu a na loop bụ nke kacha nta, na ugbu a bụ nke kasị ukwuu (na-ezo aka AC mgbaàmà na F = "F0"). The lc resonant sekit nwere ọrụ nke ugboro nhọrọ, nke nwere ike họrọ AC mgbaàmà na ụfọdụ ugboro F..

N'ihe gbasara conductivity nke eriri igwe, gịnị kpatara eriri ọla kọpa ji dị mma karịa eriri aluminom? Nke mbụ, n'ihe gbasara conductivity, conductivity nke aluminom dị ala karịa nke ọla kọpa. Iji nagide eriri ọla kọpa, wires magnetik aluminom nwere ike ịchọ akụkụ obe ka ukwuu ka ha nwee ike inye otu ọkwa nke conductivity. Nke ahụ bụ, ma e jiri ya tụnyere eriri ọla kọpa nke otu nha, ọnya ikuku na waya aluminom chọrọ olu karịa.

Nke abuo, n'ihe gbasara akụrụngwa kemịkalụ, ọnụọgụ oxidation nke aluminom dị ngwa ngwa karịa nke ọla ndị ọzọ. Ọ bụrụ na ntụ ntụ aluminom na-ekpuchi ikuku, ọ ga-abụ kpamkpam oxidized n'ime ụbọchị ole na ole, na-ahapụ ezigbo ntụ ntụ. Ya mere, iji mee njikọ kwesịrị ekwesị iji hụ na arụmọrụ dị mma, ọ dị mkpa ịkwanye oyi akwa oxide nke aluminom electromagnetic waya iji gbochie kọntaktị ọzọ n'etiti aluminum na ikuku. N'ikpeazụ, site n'echiche nke ịdị irè nke ọnụ ahịa, aluminom eriri igwe nwere otu arụmọrụ chọrọ ntụgharị na waya dayameta buru ibu, nke dị ọnụ ma dị ọnụ ala karịa ọla kọpa.
