Likarolo tsa Excavator EC55 senotlolo sa polokeho ea sefofane se potolohang solenoid valve coil

Mosebetsi oa coil

1. Phello ea hona joale ea ho thibela: Matla a motlakase a ikemetseng ka har'a coil ea inductor kamehla a hanyetsa phetoho ea hona joale ea coil. Coil inductance e na le phello e thibelang ho AC hona joale, 'me boholo ba phello e thibelang e bitsoa inductance xl,' me unit ke ohm. Kamano ea eona le inductance L le AC frequency F ke xl=2πfl. Li-inductors li ka aroloa haholo-holo ka li-coil tsa maqhubu a phahameng le li-coke coke tse fokolang maqhubu.

2. Tokiso le khetho ea makhetlo: potoloho ea lc tuning e ka thehoa ka ho hokahanya coil ea inductance le capacitor ka ho tšoana. Ke hore, maqhubu a tlhaho a oscillation f0 ea potoloho a lekana le frequency f ea lets'oao le sa fetoheng, ka hona, inductive reactance le capacitive reactance ea potoloho le tsona lia lekana, kahoo matla a motlakase a oscillates ho ea pele le pele ho inductance. capacitance, e leng ketsahalo ea resonance ea potoloho ea lc. Ha resonance, reactance inductive le capacitive reactance ea potoloho lia lekana ebile li fapane. Inductance ea kakaretso ea hona joale ka loop ke e nyenyane ka ho fetisisa, 'me hona joale ke eona e kholo ka ho fetisisa (e bua ka letšoao la AC le F = "F0"). Potoloho ea lc resonant e na le ts'ebetso ea khetho ea khafetsa, e ka khethang lets'oao la AC ka maqhubu a itseng a F.

Mabapi le conductivity ea coil, ke hobane'ng ha koporo ea koporo e le molemo ho feta aluminium? Pele ho tsohle, mabapi le conductivity, conductivity ea aluminium e tlase ho feta ea koporo. E le ho boloka li-coil tsa koporo, lithapo tsa aluminium magnetic li ka 'na tsa hloka karolo e kholoanyane ea sefapano e le hore li ka fana ka boemo bo tšoanang ba conductivity. Ke ho re, ha ho bapisoa le khoele ea koporo ea boholo bo lekanang, leqeba le tsoelipanang le terata ea aluminium le hloka molumo o eketsehileng.

Taba ea bobeli, mabapi le thepa ea lik'hemik'hale, sekhahla sa oxidation sa aluminium se potlakile ho feta sa litšepe tse ling. Haeba phofo ea aluminium e pepesehetse moeeng, e tla ba oxidized ka ho feletseng ka matsatsi a seng makae feela, e siea phofo e ntle e tšoeu. Ka hona, e le ho etsa khokahanyo e nepahetseng ho netefatsa conductivity e ntle, hoa hlokahala ho phunya oxide layer ea aluminium electromagnetic terata ho thibela ho kopana ho eketsehileng pakeng tsa aluminium le moea. Qetellong, ho ea ka pono ea ho boloka litšenyehelo, aluminium ea coil e nang le ts'ebetso e ts'oanang e hloka ho chenchana ho eketsehileng le lithapo tse kholoanyane tsa bophara, tse theko e boima le tse fokolang ho feta khoele ea koporo.
