ʻO nā ʻāpana excavator EC55 pailota laka palekana e hoʻololi ana i ka solenoid valve coil

Hana o ka wili

1. Ka hopena o kēia manawa: ʻO ka ikaika electromotive i hoʻokomo ʻia iā ia iho i loko o ka coil inductor e kūʻē mau i ka hoʻololi o kēia manawa i ka coil. Loaʻa i ka inductance coil ka hopena blocking ma ka AC current, a ʻo ka nui o ka hopena blocking i kapa ʻia inductance xl, a ʻo ka ʻāpana he ohm. ʻO kona pilina me ka inductance L a me ke alapine AC F he xl=2πfl. Hiki ke hoʻokaʻawale nui ʻia nā inductors i loko o nā wili choke kiʻekiʻe a me nā coils choke haʻahaʻa.

2. Koho a me ke alapine: hiki ke hana ʻia kahi kaapuni hoʻoheheʻe lc ma ka hoʻopili ʻana i kahi coil inductance a me kahi capacitor i ka like. ʻO ia hoʻi, ua like ka alapine oscillation maoli f0 o ke kaapuni me ke alapine f o ka hōʻailona non-alternating, no laila ua like pū ka inductive reactance a me ka capacitive reactance o ke kaapuni, no laila e hoʻohuli ʻia ka ikehu electromagnetic i hope a i waho i ka inductance a capacitance, ʻo ia ke ʻano resonance o ke kaapuni lc. Ma ka resonance, ua like ka reactance inductive a me ka capacitive reactance o ke kaapuni. ʻO ka inductance o ka huina o kēia manawa i loko o ka loop ka mea liʻiliʻi loa, a ʻo ka nui o kēia manawa (e pili ana i ka hōʻailona AC me F = "F0"). Loaʻa i ka lc resonant circuit ka hana o ke koho alapine, hiki ke koho i ka hōʻailona AC me kahi alapine F..

E pili ana i ka conductivity o ka coil, no ke aha i ʻoi aku ka maikaʻi o ka coil coil ma mua o ka coil alumini? ʻO ka mea mua, ma ke ʻano o ka conductivity, ʻoi aku ka haʻahaʻa o ka conductivity o ka alumini ma mua o ke keleawe. I mea e hoʻomau ai i nā wili keleawe, pono paha nā uea alumini magnetic i kahi ʻāpana keʻa nui aʻe i hiki iā lākou ke hāʻawi i ka pae like o ka conductivity. ʻO ia hoʻi, ke hoʻohālikelike ʻia me ka coil coil o ka nui like, ʻo ka ʻeha wili me ka uea alumini e pono ai ka nui.

ʻO ka lua, ma ke ʻano o nā waiwai kemika, ʻoi aku ka wikiwiki o ka oxidation o ka alumini ma mua o nā metala ʻē aʻe. Inā ʻike ʻia ka pauka alumini i ka ea, e hoʻoheheʻe ʻia i loko o nā lā liʻiliʻi wale nō, e waiho ana i kahi pauka keʻokeʻo maikaʻi. No laila, i mea e hoʻopili pono ai e hōʻoia i ka conductivity maikaʻi, pono ia e hou i ka papa oxide o ka alumini electromagnetic uea e pale aku ai i ka pilina ma waena o ka alumini a me ka ea. ʻO ka mea hope loa, mai ka hiʻohiʻona o ke kumu kūʻai, ʻo ka alumini coil me ka hana like e pono ai ka nui o nā huli a me nā uea anawaena nui, ʻoi aku ka maikaʻi a ʻoi aku ka waiwai ma mua o ka coil coil.
