Iimpazamo ezi-5 ekufuneka uziphephe xa usenza ngokwezifiso iiMagnets zeNeodymium eziBunjwe nge-U

Iimagnethi ze-neodymium ezimile okwe-U zinamandla amakhulu. Uyilo lwazo olukhethekileyo lugxininisa intsimi yemagnethi enamandla kakhulu kwindawo encinci, nto leyo eyenza ukuba zilungele ukusetyenziswa okufunwayo njengee-magnetic chucks, ii-sensors ezikhethekileyo, ii-motors ezine-torque ephezulu, kunye nezixhobo eziqinileyo. Nangona kunjalo, ukusebenza kwazo okunamandla kunye nokuma kwazo okuntsonkothileyo kwenza kube nzima ukuzenza ngokwezifiso. Impazamo enye inokukhokelela ekuchithekeni kwemali, ukulibaziseka kweprojekthi, okanye ukungaphumeleli okuyingozi.

 

Ziphephe ezi mpazamo zi-5 ezibalulekileyo ukuqinisekisa ukuba iimagnethi zakho ze-neodymium ezimile okwe-U zisebenza ngokugqibeleleyo nangokukhuselekileyo:

 

Impazamo #1: Ukungayinaki into yokuba izinto zithambile kwaye zixinezelekile

 

Ingxaki:Iimagnethi zeNeodymium (ingakumbi ezo zinamandla njengeN52) zibuthathaka ngokwemvelo, njengeporcelain entle. Iikona ezibukhali zesimo se-U zenza iindawo zoxinzelelo lwendalo. Ukusilela ukuqikelela oku buthathaka xa kucaciswa ubukhulu, ukunyamezela, okanye iimfuno zokuphatha kunokukhokelela kwiintanda okanye ukwaphuka okukhulu ngexesha lokwenziwa, ukwenziwa kwemagnethi, ukuthunyelwa, kwanokufakelwa.

Isisombululo:

Cacisa iRadiyusi Enkulu:Funa eyona radius inkulu yekona yangaphakathi (R) enokukwazi ukuyiphatha uyilo lwakho. Ukugoba okuqinileyo kweedigri ezingama-90 akuvumelekanga.

Khetha ibakala elifanelekileyo:Ngamanye amaxesha umgangatho ophantsi kancinci (umz., i-N42 endaweni ye-N52) unokubonelela ngokuqina okungcono kokuqhekeka ngaphandle kokulahlekelwa ngamandla amaninzi afunekayo.

Xoxa ngeemfuno zokusingatha:Qinisekisa ukuba umenzi wakho uyaqonda indlela eziza kuphathwa ngayo iimagnethi kwaye zifakelwe ngayo. Basenokucebisa ukupakishwa okukhuselekileyo okanye izixhobo zokuphatha.

Kuphephe imilenze ebhityileyo:Imilenze emincinci kakhulu xa ithelekiswa nobukhulu kunye namandla emagnethi inokunyusa kakhulu umngcipheko wokuqhekeka.

 

Impazamo #2: Uyilo ngaphandle kokuqwalasela icala lemagnetization

 

Ingxaki:Iimagnethi zeNdFeB zifumana amandla azo ngokutsala umbane kwicala elithile emva kokutsha. Kwiimagnethi ezimile okwe-U, iipali zihlala zisemaphethelweni emilenze. Ukuba uchaza imo okanye ubungakanani obuntsonkothileyo obuthintela isixhobo sokutsala umbane ukuba singadibani kakuhle nobuso beepali, imagnethi ayizukufikelela kumandla ayo aphezulu okutsala umbane okanye inokubangela iimpazamo zokutsala umbane.

Isisombululo:

Thetha kwangethuba:Xoxa ngoyilo lwakho nomenzi wemagnethi ngaphambi kokuba ulugqibezele. Kwaye ubuze ngeemfuno kunye nemida yemagnethi.

Beka phambili ukufikeleleka kobuso bepali:Qinisekisa ukuba uyilo luvumela ukufikelela okucacileyo nokungathintelwanga kwe-magnetizing coil kumphezulu wonke wesiphelo ngasinye sepali.

Qonda indlela oqhele ukuya kuyo:Cacisa ngokucacileyo indlela omawuyijonge ngayo imagnetization (ngokuthe ngqo kwipali) kwiinkcukacha zakho.

 

Impazamo #3: Ukungawuthatheli ngqalelo ukubaluleka kokunyamezelana (okanye ukukuqinisisa kakhulu)

 

Ingxaki:Iimagnethi ze-Sintered Nd ziyancipha ngexesha lenkqubo yokuvelisa, nto leyo eyenza ukuba umatshini wokulungisa emva kokutshiza ube nzima kwaye ube yingozi (jonga iMpazamo #1!). Ukulindela ukunyamezelana "kwesinyithi esenziwe ngomatshini" (± 0.001 in.) akunangqiqo kwaye kubiza kakhulu. Ngokwahlukileyo koko, ukuchaza ukunyamezelana okubanzi kakhulu (± 0.1 in.) kunokubangela ukuba imagnethi ingasetyenziswa kwindibano yakho.

Isisombululo:

Qonda imigangatho yoshishino:Qonda ukunyamezelana okuqhelekileyo "okune-sintered" kwiimagnethi zeNdFeB (ngokwesiqhelo ±0.3% ukuya ku-±0.5% yobukhulu, kunye nokunyamezelana okuncinci ngokuqhelekileyo ±0.1 mm okanye ±0.005 in.).

Yiba nobuchule:Cacisa ukunyamezelana okuqinileyo kuphela apho kubaluleke khona ukusebenza, njengeendawo zokuzalelana. Kwezinye iimeko, ukunyamezelana okuphantsi kunokonga iindleko kwaye kunciphise umngcipheko.

Xoxa ngokusila:Ukuba umphezulu kufuneka ucace kakhulu (umz., ubuso obuthi tyuki), chaza ukuba ukugaywa kuyafuneka. Oku kunokongeza iindleko ezinkulu kunye nomngcipheko, ngoko ke yisebenzise kuphela xa kuyimfuneko. Qinisekisa ukuba umenzi uyazi ukuba zeziphi iindawo ezifuna ukugaywa.

 

Impazamo #4: Ukungawunaki ukhuseleko lokusingqongileyo (iingubo)

Ingxaki:Iimagnethi ze-neodymium ezingenanto zibola ngokukhawuleza xa zichatshazelwe kukufuma, ukufuma, okanye iikhemikhali ezithile. Ukubola kuqala kwiikona zangaphakathi ezibuthathaka kwaye kunciphisa ngokukhawuleza ukusebenza kwemagnethi kunye nokuqina kwesakhiwo. Ukukhetha ukugquma okungalunganga, okanye ukucinga ukuba ukugquma okuqhelekileyo kwanele kwiindawo ezinzima, kunokukhokelela ekuphupheni kwangethuba.

Isisombululo:

Ungaze uyityeshele into yokugquma:I-NdFeB engenanto ayifanelekanga kwiimagnethi ezisebenzayo.

Iingubo kufuneka zihambelane nokusingqongileyo:Iplating eqhelekileyo ye-nickel-copper-nickel (Ni-Cu-Ni) ifanelekile kwiindlela ezininzi zangaphakathi. Kwiindawo ezimanzi, ezimanzi, ezingaphandle, okanye ezivezwe kwiikhemikhali, chaza uphahla oluqinileyo olufana nolu:

I-Epoxy/Parylene:Ukumelana okugqwesileyo komswakama kunye neekhemikhali, kunye nobushushu bombane.

Igolide okanye i-zinc:ukuxhathisa ukugqwala okuthile.

I-epoxy etyebileyo:kwiindawo ezinobungozi.

Cacisa indawo engaphakathi egubungele ikona:Gxininisa ukuba uphahla kufuneka lugqume ngokulinganayo, ingakumbi kwiikona zangaphakathi ezixineneyo zohlobo lwe-U. Buza ngesiqinisekiso sabo somsebenzi.

Cinga ngovavanyo lokutshiza ityuwa:Ukuba ukumelana nokugqwala kubalulekile, chaza inani leeyure zovavanyo lokutshiza ngetyuwa (umz., i-ASTM B117) ekufuneka idlule kwimagnethi egqunyiweyo.

 

Impazamo #5: Ukutsiba iSigaba sePrototype

Ingxaki:Kukho iingozi zokutsiba kwi-odolo enkulu ngokusekelwe kwimodeli ye-CAD okanye iphepha ledatha kuphela. Izinto zokwenyani ezifana nokusasazwa kwe-magnetic pull, ukulingana kwangempela kwezinto, ukuphathwa kobuthathaka, okanye ukusebenzisana okungalindelekanga kunokubonakala kuphela ngesampulu ebonakalayo.

 

Isisombululo:

Yenza i-odolo yeeprototypes: bhajethi kwaye ugxininise iqela elincinci leeprototypes kuqala.

Vavanya ngokungqongqo: Jonga iiprototypes zeemeko zehlabathi lokwenyani:

Qinisekisa ukuba ifanelekile kwaye isebenza kakuhle kwindibano.

Ukulinganisa ukutsala okwenyani (ingaba kuyahlangabezana neemfuno zakho?).

Uvavanyo lokuphatha (ingaba luya kusinda ekufakweni?).

Uvavanyo lokuvezwa kokusingqongileyo (ukuba lukhona).

Phinda-phinda njengoko kufuneka: Sebenzisa impendulo yeprototype ukuze uphucule ubukhulu, ukunyamezelana, ukugquma, okanye amanqanaba ngaphambi kokuba uzibophelele kwimveliso ebiza kakhulu.
