Ukukhetha okubalulekile kazibuthe
Ukukhetha inketho efanele kazibuthe yohlelo lwakho lokusebenza kungaba inselele.Kunezinhlobonhlobo zezinto zikazibuthe ongakhetha kuzo, ngayinye enezici ezihlukile zokusebenza.Njengomhlinzeki ozibuthe ochwepheshile, ngolwazi lwethu oluningi kukazibuthe, singakusiza wenze ukukhetha okufanele.
Izinhlobonhlobo zezinto ezitholakalayo ziyatholakala, okuhlanganisa omagnethi be-neodymium (NdFeB noma umhlaba ongavamile), omagnethi be-alnico (AlNiCo), samarium cobalt (SmCo) noma omazibuthe be-ferrite (ceramic).Ngaphezu kwalokho, kunezinguqulo ezahlukene ezifana nozibuthe kagesi, ozibuthe abaguquguqukayo kanye nozibuthe ababoshiwe.Ukukhetha impahla efanele kuyisihluthulelo sephrojekthi ephumelelayo.
Zingaki izinhlobo ezahlukene zikamazibuthe ezikhona
Izigaba ezilula zalezi zidonsa zingenziwa ngokusekelwe ekubunjweni kozibuthe abahlukahlukene kanye nomthombo wamagnetism wabo.Izibuthe ezihlala zikazibuthe ngemva kokusebenza kazibuthe zibizwa ngokuthi ngozibuthe baphakade.Okuphambene nalokhu yizibuthe zikagesi.I-electromagnetic ikazibuthe yesikhashana esebenza kuphela njengozibuthe ongunaphakade lapho iseduze nendawo kazibuthe, kodwa ilahlekelwa yilo mphumela ngokushesha lapho isuswa.
Ozibuthe baphakade bavame ukuhlukaniswa ngezigaba ezine ngokuya ngezinto zabo: i-NdFeB, i-AlNiCo, i-SmCo ne-ferrite.
I-Neodymium iron boron (NdFeB) - ngokuvamile aziwa ngokuthi i-neodymium iron boron noma ozibuthe be-NEO - ozibuthe bomhlaba abayivelakancane abenziwe nge-alloying neodymium, insimbi ne-boron, futhi bangamazibuthe abaqine kakhulu abakhona namuhla.Vele, i-NdFeB ingahlukaniswa ibe yi-NdFeB ehlanganisiwe, i-NdFeB eboshwe, umjovo wokucindezela i-NdFeB nokunye.Nokho, ngokuvamile, uma singacacisi ukuthi yiluphi uhlobo lwe-Nd-Fe-B, sizobhekisela ku-Sintered Nd-Fe-B.
Samarium Cobalt (I-SmCo) - eyaziwa nangokuthi i-rare earth cobalt, i-rare earth cobalt, i-RECo ne-CoSm - azinamandla njengozibuthe we-neodymium (NdFeB), kodwa anikeza izinzuzo ezintathu ezinkulu.Ozibuthe benziwe nge-SmCo bangasebenza ebangeni lokushisa elibanzi, babe ne-coefficient ephezulu yezinga lokushisa futhi bamelana nokugqwala.Ngenxa yokuthi i-SmCo ibiza kakhulu futhi inalezi zakhiwo ezihlukile, i-SmCo ivamise ukusetshenziswa ezinhlelweni zezempi nezasemoyeni.
I-Aluminium-Nickel-Cobalt (I-AlNiCo) - Zontathu izingxenye eziyinhloko ze-AlNiCo - i-aluminium, i-nickel ne-cobalt.Nakuba zikwazi ukumelana nokushisa, zikhishwa kalula uzibuthe.Kwezinye izinhlelo zokusebenza, zivame ukushintshwa yizibuthe ze-ceramic nezingavamile.I-AlNiCo ivame ukusetshenziswa empilweni yansuku zonke ngezicelo ezimile nezokufundisa.
I-Ferrite- Ozibuthe be-Ceramic noma be-ferrite abangunaphakade ngokuvamile benziwa nge-sintered iron oxide ne-barium noma i-strontium carbonate futhi ababizi futhi kulula ukukhiqiza ngokusinsa noma ngokucindezela.Lolu ngolunye lwezinhlobo ezisetshenziswa kakhulu kazibuthe.Ziqinile futhi zingasuswa kalula uzibuthe.
Ozibuthe baphakade bangahlukaniswa ngezigaba ezilandelayo ngokuhlukaniswa kwezinguqulo ezahlukene:
I-Sintering-ukuguqulwa kwezinto eziyimpuphu zibe imizimba eminyene futhi kuyinqubo yendabuko.Abantu bebelokhu besebenzisa le nqubo isikhathi eside ukukhiqiza izitsha zobumba, i-powder metallurgy, izinto eziphikisayo, izinto zokushisa eziphakeme kakhulu, njll. Ngokuvamile, umzimba ominyene otholwe ngokucwilisa ngemuva kokubunjwa kwempushana uyinsimbi ye-polycrystalline ene-microstructure. ehlanganisa amakristalu, i-vitreous humor nama-pores.Inqubo ye-sintering ithinta ngokuqondile usayizi wokusanhlamvu, usayizi we-pore kanye nokuma nokusabalalisa kwemingcele yokusanhlamvu ku-microstructure, okubuye kuthinte izakhiwo zezinto.
I-Bonding - Ukuhlanganisa akuyona inguqulo eyingqayizivele ngomqondo oqinile wegama, njengoba ukuhlanganisa kuwukuhlanganisa izinto ezihlanganisiwe ngokusebenzisa into enamathelayo.Ngale ndlela ama-eddy currents akhiqizwa ngesikhathi sokufakwa kukazibuthe angancishiswa, athuthukise kakhulu ukwethembeka kukazibuthe ngesikhathi sokusetshenziswa.
Ukubumba Umjovo - Ukubumba umjovo kuyindlela yokukhiqiza izimo zemikhiqizo yezimboni.Imikhiqizo ijwayele ukubunjwa kusetshenziswa ukubumba komjovo wenjoloba kanye nokubumba komjovo wepulasitiki.Ukubumba umjovo kungabuye kuhlukaniswe ngendlela yokubumba umjovo kanye nendlela yokufaka ukufa.Ukusebenzisa ukubumba komjovo njengendlela yokukhiqiza kunganikeza amathuba amaningi okwakheka kazibuthe.Ngenxa yezakhiwo zawozibuthe ngokwazo, omagnethi aba-sintered bavamise ukuba nama-brittle futhi kube nzima ukukhiqiza izimo ezithile.Indlela yokubumba umjovo ivamise ukwenza ukubunjwa okuningi kwenzeke ngokuhlanganisa ezinye izinto.
I-Flexible Magnet- Uzibuthe oguquguqukayo unguzibuthe ongakwazi ukugoba futhi ukhubazeke futhi izakhiwo zawo kazibuthe zihlale zinjalo.Lawa mamagnets ngokuvamile enziwa ngezinto eziguquguqukayo, njengerabha, i-polyurethane, njll., futhi axutshwe nempushana kazibuthe ukuze abenze kazibuthe.Ngokungafani nozibuthe bendabuko abaqinile, ozibuthe abaguquguqukayo bavumelana nezimo futhi bathambile, ngakho bangasikwa futhi bagotshwe ngezindlela ezihlukahlukene njengoba kudingeka.Futhi zinezakhiwo ezingcono zokunamathela futhi zingasetshenziselwa a
I-Solenoid: Okuphambene nozibuthe unomphela yizibuthe zikagesi, ezingabuye zibizwe ngokuthi uzibuthe wesikhashana.Lolu hlobo lukazibuthe luyikhoyili eyenza iluphu ngokusonga izintambo entweni ewumgogodla, eyaziwa nangokuthi i-solenoid.Ngokudlula ugesi ku-solenoid, inkambu kazibuthe esetshenziselwa ukudonsa uzibuthe kagesi iyakhiqizwa.Inkambu kazibuthe enamandla kunazo zonke yenzeka ngaphakathi kwekhoyili, futhi amandla enkundla akhula ngenani lamakhoyili namandla wamanje.Ama-electromagnets avumelana nezimo futhi angakwazi ukulungisa isiqondiso senkundla kazibuthe ngokuya ngesiqondiso samanje, futhi angalungisa amandla amanje njengoba kudingeka ukuze kuzuzwe amandla kazibuthe afunekayo.
