Imvelaphi kunye neMbali

Amagnethi asisigxina yinxalenye ebalulekileyo yobomi banamhlanje. Bafunyanwa kwi okanye basetyenziselwa ukuvelisa phantse yonke into elula namhlanje. Iimagnethi zokuqala ezisisigxina zaveliswa kumatye avela ngokwendalo abizwa ngokuba ziindawo zokuhlala. La matye aqala ukufundwa kwiminyaka engama-2500 eyadlulayo ngamaTshayina kwaye kamva amaGrike, afumana eli litye kwiphondo laseMagnetes, apho lafumana khona igama. Ukusukela ngoko, iipropathi zezixhobo zemagneti ziphuculwe kakhulu kwaye namhlanje izixhobo ezisisigxina zemagneti zinamandla angaphezulu kwamaxesha kumandla ombane wangaphambili. Igama elisisigxina semagnethi lisuka kubukho bemagneti yokubamba isimangalo sombane emva kokuba ikususiwe kwifowuni yokwenza umazibuthe. Ezo zixhobo zinokuba zezinye iimagnethi zombane ezisisigxina, i-electro-magnets okanye i-coils yecingo ehlawuliswa ngokufutshane ngombane. Amandla abo okubamba umrhaji wombane enza ukuba babe luncedo ekubambeni izinto zibekwe endaweni, ukuguqula umbane kumandla okususa kunye nokuphikisana (motors kunye nejeneretha), okanye kuchaphazele ezinye izinto ezizisiweyo kufutshane nabo.

uyilo

Ukusebenza ngokuphezulu kwemagnethi ngumsebenzi wobunjineli wombane ongcono. Kubathengi abafuna uncedo yoyilo okanye uyilo oluntsonkothileyo wesekethe, QM's Iqela leenjineli zesicelo esinamava kunye neenjineli ezinolwazi lwentengiso yendawo yakho. QM Iinjineli zisebenza kunye nabathengi ukuphucula okanye ukuqinisekisa uyilo olukhoyo kunye nokuphuhlisa uyilo lwenoveli oluvelisa iziphumo ezizodwa zemagneti. QM Uphuhlise uyilo lwamalungelo obunini obunikazi obunikezela ngamandla ombane, eyunifom okanye imilo ekhethekileyo eyakhelweyo yindawo ehlala itshintsha amandla ombane kunye nokungasebenzi kakuhle kwemagnethi yemagnethi kunye noyilo olusisigxina lomazibuthe. Abathengi bayazithemba xa hey beza nomqondo onzima okanye umbono omtsha wokuba QM uya kuhlangabezana nalo mngeni ngokuzoba kwiminyaka eli-10 yobungqina bemagneti obungqiniweyo. QM Unabantu, iimveliso kunye netekhnoloji ebeka oomazibuthe ukuba basebenze.

Ukukhetha uMagnetti

Ukhetho lweMagnet kuzo zonke izicelo kufuneka luthathele ingqalelo ujikelezo lwamandla kazwelonke kunye nokusingqongileyo. Apho kufanelekile iAlnico, ubungakanani bemagneti bunokucuthwa ukuba ngaba bunokufakwa umbane emva kwendibano kwisekethe yomazibuthe. Ukuba usetyenziswe ngaphandle kwezinye izinto zesekethe, njengakwimisebenzi yezokhuseleko, ubude obufanelekileyo kumda wobubanzi (onxulumene nomlinganiso wemvume yemozulu) kufuneka ube mkhulu ngokwaneleyo ukuba ubangele ukuba umazibuthe usebenze ngaphezulu kweedolo kwikhola yesibini yedemokhrasi. Kwizicelo ezibaluleke kakhulu, ii-Alnico magnets zinokulinganiselwa kwixabiso lesiseko soxinaniso lweflux.

Imveliso ephuma kwimveliso yokuqina ephantsi kukuziva unoluvo lwe demagnetizing iziphumo ngenxa yemagnethi yangaphandle yokothuswa, ubushushu, kunye nobushushu besicelo. Kwizicelo ezibuthathaka, i-Alnico magnets inokuthi ibe nozinzo lobushushu ukunciphisa le miphumo Kukho iiklasi ezine zemagnethi zentengiso zangoku, nganye nganye ixhomekeke kubume bezinto zabo. Kwiklasi nganye kukho usapho lwamabakala olunezinto zazo zemagneti. Ezi klasi ziqhelekileyo zezi:

  • I-Neodymium Iron Boron
  • ISamarium Cobalt
  • -omdongwe
  • Alnico

I-NdFeB kunye neSmCo zidibene ngoku zibizwa ngokuba ziiRare Earth magnets kuba zombini ziqulunqwe zizinto ezivela kwiqela lezinto zomhlaba eziRare. I-Neodymium Iron Boron (iqulathe ngokubanzi i-Nd2Fe14B, edla ngokuphunculwa kwi-NdFeB) lolona lwentengiso lutsha kusapho lwezixhobo zemagneti zala maxesha. Kumaqondo obushushu egumbi, ii-magnets ze-NdFeB zibonisa ezona zakhiwo ziphakamileyo zazo zonke izixhobo zemagneti. ISamarium Cobalt yenziwa kwiintlobo ezimbini zeentlobo: iSm1Co5 kunye neSm2Co17 - zihlala zibizwa ngokuba ziintlobo zeSmCo 1: 5 okanye iSmCo 2:17. Iindidi ezingama-2:17, ezinamaxabiso aphezulu e-Hci, zibonelela ngozinzo olukhulu kunoludidi lwe-1: 5. I-Ceramic, ekwabizwa ngokuba yi-Ferrite, iignets (ukubumba ngokubanzi i-BaFe2O3 okanye i-SrFe2O3) zithengisiwe ukususela ngo-1950s kwaye ziyaqhubeka zisetyenziswa kakhulu namhlanje ngenxa yexabiso labo eliphantsi. Uhlobo olukhethekileyo lwe-Ceramic yemagnethi yinto "eguquguqukayo", eyenziwe ngokubopha umgubo weCeramic kwibhanti eguquguqukayo. I-Alnico magnets (eyakhiwe ngokubanzi i-Al-Ni-Co) yathengiswa ngo-1930s kwaye isasetyenziswa kakhulu nanamhlanje.

Ezi zixhobo zigqithisa uluhlu lweepropati ezamkela uluhlu lweemfuno ezahlukeneyo zesicelo. Oku kulandelayo kwenzelwe ukuba kunikezwe isishwankathelo esibanzi kodwa esisebenzayo sezinto ekufuneka ziqwalaselwe ekukhetheni isixhobo esifanelekileyo, umgangatho, imilo nobungakanani bemagnethi kwisicelo esithile. Isicangca esingezantsi sibonisa amaxabiso aqhelekileyo ezimpawu eziphambili zamabakala akhethiweyo ezinto ezahlukeneyo zokuthelekisa. La maxabiso aza kuxutyushwa ngokweenkcukacha kula macandelo alandelayo.

Treatment surface

Amagqabantshintshi anokufuna ukuhlanganiswa ngokuxhomekeke kwisicelo esenzelwe zona. Ukudibanisa imagnethi kuphucula imbonakalo, ukumelana nokugqwala, ukukhuselwa ekunxibeni kwaye kunokuba kufanelekile kwizicelo kwiimeko ezifanelekileyo zegumbi.
I-Samarium Cobalt, izixhobo zeAlnico azinyangeki ngenkuku, kwaye akufuneki zidityaniswe ngokuchasene nokugqwala. IAlnico ifakwa lula kwiimpawu zokuhombisa.
Iignets ze-NdFeB zihlala zichaphazeleka kukonakala kwaye zihlala zikhuselekile ngale ndlela. Kukho iintlobo ngeentlobo zeengubo ezilungele imagnethi engapheliyo, Ayizizo zonke iintlobo zokupheka eziza kulungela yonke impahla okanye ijiyometri yemagnethi, kwaye ukhetho lokugqibela luya kuxhomekeka kwisicelo kunye nokusingqongileyo. Ukhetho olongezelelekileyo kukubeka umazibuthe kwikhephthi yangaphandle ukuthintela ukuvela kunye nomonakalo.

Magnetizing

Imagnethi esisigxina ebonelelwa phantsi kweemeko ezimbini, iMagnetized okanye engenazibuthe, ihlala ingaphawulwanga ubunyani bayo. Ukuba umsebenzisi ufuna, sinokumakisha ubumbano ngeendlela ekuvunyelenwe ngazo. Xa ubeka iodolo, umsebenzisi kufuneka azise ngemeko yokunikezelwa kwaye ukuba uphawu lwencam iyimfuneko.

Intsimi yemagneti yemagnethi engapheliyo inxulumene nohlobo olusisigxina lwezinto zemagneti kunye namandla ayo achukumisayo okusebenzisana. Ukuba umazibuthe ufuna umbane kunye nedagnetization, nceda unxibelelane nathi ucele inkxaso yobuchule.

Zimbini iindlela zokufaka umazibuthe: Intsimi yeDC kunye nokudonsa amandla kazibuthe.

Zintathu iindlela zokwenza ukuba i-demagnetize umazibuthe: inkqubo yedemokhrasi ngokutshisa yindlela ekhethekileyo yokusebenza. demagnetization kwicandelo le-AC. Idemokhrasi kwibala leDC. Oku kucela amandla ombane anamandla kakhulu kunye nobuchule obuphezulu be-demagnetization.

Ubume bejometri kunye nesikhokelo sombane kumazibuthe osisigxina: ngokomgaqo, sivelisa umazibuthe osisigxina kwiimpawu ezahlukeneyo. Ngokwesiqhelo, kubandakanya ibhloko, i-disc, umsesane, icandelo

Uluhlu lobungakanani, ubungakanani kunye nokunyamezelana

Ngaphandle kobukhulu kwicala lokujikeleza kwamandla ombane, ubukhulu bomda osisigxina we-magnethi engapheliyo awugqithi kwi-50mm, encitshiswa yintsimi yokuqhelanisa nezixhobo zokona. Ubungakanani kwicala le-unmagnetization lide liye kufika kwi-100mm.

Unyamezelo luhlala +/- 0.05 - +/- 0.10mm.

Imigaqo yokhuseleko yokusebenza kwemanyuwali

1. Imagnethi engapheliyo enemagnethi eyomeleleyo inomtsalane kwisinyithi kunye nezinye izinto zemagnethi eziwangqongileyo. Ngaphantsi kwemeko eqhelekileyo, umqhubi wesandla kufuneka alumke kakhulu ukunqanda nawuphi na umonakalo. Ngenxa yamandla ombane anamandla, umazibuthe omkhulu osondele kubo uthatha umngcipheko womonakalo. Abantu bahlala bezicwangcisa ezi zignethi ngokwahlukeneyo okanye ngeetshathi. Kule meko, siya kukhuphela iiglavu zokukhusela ezisebenzayo.

2. Kule meko yommandla wamandla ombane omeleleyo, nayiphi na into evakalayo enokusetyenziswa ngombane kunye nemitha yovavanyo inokutshintshwa okanye yonakaliswe. Nceda ubone ukuba ikhompyuter, umboniso kunye nemithombo yeendaba yemagneti, umzekelo, idiski yemagneti, ikhasethi yomazibuthe kunye nevidiyo yokurekhoda njlnjl., Zikude kakhulu kwizinto ezinomthi, zitsho kude kune-2m.

3. Ukudibana kwemikhosi ekhangayo phakathi kwezibuthe ezibini ezingapheliyo kuya kuzisa ukukhanya okukhulu. Ke ngoko, izinto ezinokutsha okanye eziqhushumayo akufuneki zibekwe zijikeleze bona.

4. Xa umazibuthe utyhilelwe i-hydrogen, akuvunyelwanga ukuba usebenzise imagnethi engapheliyo ngaphandle kokugada ukhuseleko. Isizathu kukuba i-sorption ye-hydrogen iya kutshabalalisa ubume bemagnethi kwaye ikhokelele ekuqulunqweni kwakhona kweempawu zemagnethi. Ekuphela kwendlela yokukhusela umazibuthe ngokukuko kukufihla imagnethi kwimeko kwaye uyitywine.
