Uila kila: ka? Iecaianoaaiiuo a me ka hoʻohana '

Ke? Iecaianoaaiiie o keia ano keia ano o ke kila ninoaaeyao he alakaʻi o wahi i waena o nāʻume mākenēki mea. Uila kila - he oka a pau o ka hao me ka silikone me ka nui o ka mai 0.5% a 5%. He ākea hiʻona o keia ano keia ano o nā huahana hiki ke wehewehe ma ke kiʻekiʻe electromagnetic a me mechanical waiwai. Ua hanaʻia mai kila ia, he pono ole eiiiiiaiou, ma a ole nele. Ua wehewehe kona haʻahaʻa kāki.

Kanawai o ka silikone

Kēia ke keʻena i loko o ka huipūʻana me ka hao, e hana i kekahi anuanu pāʻoihana o ke kiʻekiʻe resistivity, ke kumukuai o ka i hilinaʻi nui ma luna o ka pakeneka o silikone i loko o ka oka a pau. Ma lalo o ka aoao o ka mea ma luna o ke gula hao, ka mea haalele i konaʻume mākenēki waiwai. Akā, i ka wā kokoke ana i kulanui, ma ka mea ku ole, he maikaʻi hopena. ua mahuahua a me ka hana hou ana i ke kumupaʻa o ka metala ke permeability o ka hao. hiki e wehewehe i ka pono kanawai o ka silikone (Si) like penei. Ma lalo o ka aoao o keia hehee ai ke hele mai i loko o graphite kalapona hoʻololi moku'āina o ka cementite i loaʻa lowerʻume mākenēki waiwai. Ke hehee ai Si mai he adverse ia ma luna o ka ka ho'ēmiʻana o ka hoʻokomo. Kona keiki kŰlń ao i ka thermal conductivity, a me ka pa apŘ o ka hao.

Impurities i loko o ka haku mele

Ma ka 'ole uila kila ke komo' ē nā mea hoʻohui: luaipele, kalapona, manganese, phosphorus a me na mea e ae. Ka loa nā palapala poʻe - kalapona (C). Ua hiki ia ia ma ke ano like cementite, a me ka graphite. Ua loaʻa kekahi mau 'ole ma o ka oka a pau, e like me ka pono me ka pakeneka o ke kalapona maʻiʻo. E pale hua'ōlelo i makemake inclusions hehee ai C, kila hiki ole ke ho'ēmi no ka mea e hiki mai ana koke kūnewa a noaaeeecaoee.

Adverse 'ole ma luna o ka waiwai o ka mea i na kēia eiiiiiaiou: oxygen, ka luaipele a me ka manganese. Ka mea, emi konaʻume mākenēki ano. E noa ka hao i loko o kona haku mele 'ana pono i impurities. Eia, ka mea, i ia e ia i loko o no me ka a pau,ʻaʻole like me ka hao maemae.

He hiki ke hoʻoikaika waiwai o ke kila ma ka ana hoʻomaʻemaʻe mai impurities. Akā, i kēia papa hana, ua pono i ka mea nui-unahiʻole, i? Iecaianoaaiiuo,ʻaʻole e mau ana. Akā, ma ka huʻihuʻi ua hiolo kuina uila kila 'ano apau loa i kaʻume mākenēki waiwai i loko o kona' ole. Ua apono 'oe, e kū ai i ka maikaʻi i nā hualoaʻa. Akā, mau pono no hoi ia ia i kī pū.

anu ua hiolo

No ka lōʻihi manawa, ua manaoio ia silikone maoli ka brittleness o ke kila. ? Iecaianoaaiiuo i wahiʻano nui ma ka wela ua hiolo. Ka puka waiwai anu ua hiolo ua haʻahaʻa.

Wale ma hope o ka mea, ua loaʻa i ka anu hana ma ka olelo maoli i kaʻume mākenēki waiwai o ka mea, ia i ua hoʻomano hoʻohana. ua hōʻike lākou iā lākou iho Other wahi me kaʻino lima wale. Anu ape he pono ia ma luna o ka ÿano waiwai, e like me ka hoʻomaikaʻi i ka mea e like ai o ka pepa luna, ka waviness, a māhuahua kona pūnaewele hahi.

Kiʻiona waiwai i loaa uila kila ma ka hoʻohana 'ana o ke anu hana hiki ke wehewehe ma ke kahua ma loko o crystallographic hionapāʻili. Ua ua hookoaiaʻe e kekahi mau degere. Lakou, ma ka huli, hilinai ma ka mahana i a ua hiolo ae, i ka i ka mea ua crimped no hoi ma o ka mānoanoa koi 'ia o ka pepa, a ma luna o ka loa.

Kāki no ka wela olokaa kuina mānoanoa lilo 2 manawa haʻahaʻa ma mua ia o ka anuanu. Akā, i kēia hopena maikaʻi kona mea e like loa offset haahaa wela poho (o ka emi o ma kahi o elua manawa), high quality, a me ka maikai hahi hiki anuanu ua olokaaiaʻe oka a pau. Ke koena unuhi i loko o kēia mau steels - ka silikone maʻiʻo. Kona huina papa koa mai ka 3.3% i 4.5%, niioaaonoaaiii.

GOST

Manufacturers paka elua wale ke ano o ka kila e hoʻopili like i ka GOST. Ka muaʻano - 802-58 "uila olokaa". Lua - uila kila GOST 9925-61 "leki anu owili uila kila".

Kaha a me ka palapala "E", ukali ma ka helu ua, i ka helu o ka a i ka kūikawā manaʻo:

• Ka mua huahelu i loko o ka waiwai o ia hoʻi, ke degere o ka lepili kila alloying me ka silikone. Mai hoʻowahāwahā doped i ka oka a kiʻekiʻe, niioaaonoaaiii i na kii 1 i 4. Ka dynamo - he kila o ka pūʻulu A1 a me A2. Mea hoʻololi uila - E3 a me E4.
• Ka lua o ka omaka huahelu i ka laulā mai 1 a hiki i 8. Ua hōʻike i ka electromagnetic a waiwai o ka mea i ka wa ana ia i loko o kekahi pae'ōnaehana ana. No keia omaka hiki ke loaʻa i loko o i mau mea e hiki ke hoʻohana i kekahi 'ole ka' ē aʻe kila.

Digital Aʻohe ma hope o ka lua o ka huahelu Hōʻike i ke kila ua textured. Inā he mea mau 'Aʻohe hualoaʻa, laila ia mea he wahi textured.

I ka pau ana o ka omaka hiki ke loaʻa i nā kēia palapala:

• "A" - i ka ho'ākāka 'ia i mea poho i loa haʻahaʻa.
• "P" -ʻolokaʻaʻia me ka kiʻekiʻe ka ikaika a me ka kiʻekiʻeʻilikai hoʻopau.

Laulā o ka hana

Puunaueia ma ka noi oka a pau i loko o ekolu ano:

• pono no ka hoʻohana i ka kiʻekiʻe a me ka meakinoʻume mākenēki kula (ʻume mākenēki reversal maemae 50 Hz);
• pono no ka hoʻohana ma kiʻekiʻe kula ma nä alapine mai i 400 Hz;
• kila, a ua hoʻohana i ka meakino a me ka mea uukuʻume mākenēki kihapai.

uila kila lahilahi i lawe i kēia Ana: laula 240 i ka 1000 mm o, ka lōʻihi i ia mai 720 mm o ka 2000 mm o, he mānoanoa - o 0,1 i 1 mm o. Loa hoʻomano hoʻohana 'ia e textured kila, no ka mea, i ke kiʻekiʻe waiwai o ka electromagnetic a waiwai. Haumana o ka mea e pinepine ia i loko o uila wilikî.

Uila kila - waiwai

oka a kulai

• Resistivity. Mai keia inideka pono hilinaʻi nui ma luna o ka mea e like ai o ka mea. Steel ua hoʻohana 'ia i kahi e mea pono, e malama i ka uila i loko o ke alakaʻi mele, a haawi aku ia i kona ana.
• Ke coercive ikaika. Kuleana no ka hiki ana o ka naʻume mākenēki ke kahua no ka demagnetization. No kekahi mau manaʻo, i kēia hiʻona ua koi 'ia i ka loli iki ana degere. Ma transformers a me Hawaii hoʻohana 'ikamu me ka hiki kiʻekiʻe e demagnetization. Ma ka huahelu ua lilo ia i mea haʻahaʻa. Akā, i loko o nā electromagnets e pono ai, ma ka mea ku ole, he kiʻekiʻe coercive pūʻali koa. E hoʻomaʻa i kaʻume mākenēki waiwai, ke kākau i makemake pakeneka o ka silikone i loko o ke kila oka a pau.

• Ka laula o ka hysteresis loop. Kēia huahelu e e like haʻahaʻa me hiki.
• ʻume mākenēki permeability. Ke kiekie o ka huahelu, i ka maikaʻi o ka mea ua "kopina" me kā lākou mau hana.
• Ka mānoanoa o ka pepa. No ka hana ana o na mea a me na hapa mea i hoʻohana, ka mānoanoa o ka i, aole ia i oi aku mamua o hoʻokahi millimeter. Eia naʻe, inā he pono, ua hoemiia ke anakahi i kekahi waiwai o 0,1 mm o.

O ka pepa mea o ka papa mua, e hiki eʻano oʻume mākenēki wahi i puhi ai no kuapo kanaka a me regulators.

Uila kila o ka lua o ka papa hiki ke hoʻohana 'ia no me ka o ka uila DC, a AC pono, o ka Kora naʻEsau o na rotors. Ke kolu o ka papa e e pono no ka manufacturingʻume mākenēki ka Korata: no ka mana transformers, e like me ka me ka o ka nui synchronous machines.

E hana i ka'āwai no ka uila mīkini, mea, mea pono e pili i ka nou ana la o kila, ma kahi a ka kalapona maʻiʻo mea i oi aku 1%. Products i o keia mea malalo iho o gradual annealed. Kalapona kila hoʻohana 'ia i loko o ka hana o ka mīkini wahi malalo i ka kuʻihao. e ka papa kuhikuhiE kaupoku no DC machines o kēia mau ano o ka mea.

No kela mau wahi mīkini i lawe ai i ka mea i kā mākou e haawe (pūnāwai, rotors, mau pua o ka heleuma) ua hoʻohana oka a me ka kiʻekiʻe me mechanical waiwai. Oia ka mea e hoʻohui pū i ka nikala, chromium, molybdenum a me ka tungsten. Hiki e hana i kaʻume mākenēki Kora naʻEsau o ka uila kila. Ka mea, i hoʻohana 'ia no ka haʻahaʻa-alapine (frequency) transformers - 50Hz.

ʻume mākenēki koʻokoʻo

ʻume mākenēki kaʻana like ia ma luna o ke kapa kila a me ka Kora naʻEsau. Kēlā me kēia? Ueo i kona mau peculiarities.

Kookoo: ma ia verticalʻume mākenēki kookoo, a mai ka hehi keʻa pauku kākauʻia i loko o ka kaiapili. Ka mea, i hoʻonohonoho ai i ka hana paukūʻolokaʻa kinona o kaʻume mākenēki'ōwili hao.

Products o keia manao i kekahi mau huinahń kinona, a me ko lākou mau koʻokoʻo i ka laau kea maluna pauku, ka mea i hoonohonoho horizontally. Kēiaʻano o kaʻume mākenēki huakai kaapuni a ua pili wale nō ia ma luna 'manaʻo a me ka manao. No laila, i kēia mau hale a mai i lilo he ākea.

No laila, ua loaʻa i ka uila kila mea, a ma ka mea, ua hoʻohana 'ia.
