Ehamba phambili SmCo Magnets Umkhiqizi: Innovations High-Temperature Magnet Technology

Umkhiqizi Wozibuthe we-SmCo Ohamba phambili: Okuqanjwe kabusha ku-High-Temperature Magnet Technology Isithombe Esifakiwe
  • Ehamba phambili SmCo Magnets Umkhiqizi: Innovations High-Temperature Magnet Technology

Incazelo emfushane:

Ozibuthe be-Samarium-cobalt (SmCo) basetshenziswa ezinhlelweni ezihlukahlukene lapho kudingeka khona ukuzinza kwezinga lokushisa eliphezulu nezizibuthe ezinamandla.Zivame ukusetshenziswa ezimbonini ezifana ne-aerospace, izimoto, izinto zezokwelapha, kanye nemishini yokukhiqiza.Ezinye izinhlelo zokusebenza ezithize zifaka amamotho kagesi, izinzwa, amabheringi kazibuthe, nama-coupling kazibuthe.Ngenxa yokuphoqelela kwabo okuphakeme kanye nokumelana ne-demagnetization, omagnethi be-SmCo bafaneleka ngokukhethekile izimo zokusebenza ezinzima.Ozibuthe baseSamarium-cobalt (SmCo) baziwa ngamandla abo angavamile, ngokuvamile bephakathi kozibuthe abaqine kakhulu abatholakalayo.Ngokujwayelekile banomkhiqizo wamandla aphezulu, onomthelela kumandla kazibuthe wabo oqinile.Lokhu kuzenza zifaneleke kahle izinhlelo zokusebenza lapho kudingeka khona amandla kazibuthe anamandla.Kodwa-ke, amandla athile kazibuthe we-SmCo angahluka ngokuya ngebanga kanye nenqubo yokukhiqiza.Uma unohlelo oluthile engqondweni, kungase kube yinzuzo ukuxhumana nathi ukuze uthole ulwazi oluthe xaxa mayelana namandla ozibuthe be-SmCo atholakalayo ngezidingo zakho.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ngaphandle kwalokho, omagnethi be-SmCo banezinye izici:
Ukusebenza okuthembekile: Ozibuthe be-SmCo bamelana ngokwedlulele nokukhishwa kazibuthe okubenza bathembeke ezindaweni eziningi.
Ukumelana nokugqwala kanye ne-oxidation: Ngenxa yokuqukethwe kwensimbi ephansi ezintweni eziyinhlanganisela, omagnethi be-SmCo banokumelana nokugqwala okuhle kakhulu.Ngokungafani ne-NdFeB, omagnethi be-SmCo abadingi i-electroplating.
Ukuqina kwezinga lokushisa: I-SmCo ingagcina amandla ayo kazibuthe emazingeni okushisa aphezulu (249-300 ℃) namazinga okushisa aphansi kakhulu (-232 ℃).
Izinto zokwakha ezinqamukayo: Lapho i-sintering, impahla ingase ibe brittle, ngenxa yokuthi i-brittle futhi kulula ukuqhekeka, ukucubungula kunemikhawulo, lapho izindlela zokucubungula zendabuko zingasebenzi.Noma kunjalo, ingagaywa, kodwa kuphela uma kusetshenziswa inani elikhulu lokupholisa.Lokho kungenxa yokuthi okokupholisa kunganciphisa ingozi yomlilo kusukela ekuqhekekeni okushisayo nothuli olugaywe nge-oxidized.

Izicelo:
1. Izinjini ze-PM ezisezingeni eliphezulu.Amamotho ajwayelekile e-PM ajwayele ukusebenzisa omazibuthe be-ferrite noma omagnet be-NdFeB.Kodwa ezindaweni lapho izinga lokushisa lidlula ama-200 ℃ noma i-torque enkulu, ama-motor e-SmCo PM kuphela anekhono.
2. Imishini ye-Electroacoustic kumasistimu wesipikha esikhuluma phezulu.
3. Uhlelo lwensimbi oluthembeke kakhulu.Izinsimbi eziningi ezisetshenziswa ku-aerospace, izindiza, ezokwelashwa neminye imikhakha kumele zisebenzise omazibuthe abangapheli be-SmCo ukuze kuqinisekiswe ukwethembeka okuphezulu nokuphepha okuphelele.
4. Ezinhlelweni ze-radar nezokuxhumana ezibaluleke kakhulu, kusetshenziswa inani elikhulu lamashubhu amagagasi ahambayo, omagnetron, amashubhu ajahayo, amashubhu ajaha amagagasi, ama-gyrotron namanye amadivaysi kagesi evacuum asetshenziswa, kanti omazibuthe be-SmCo benza imishayo yama-electron ekuhambeni ngendlela enqunyiwe.
5. I-SmCo extractors kazibuthe emithonjeni ejulile engaphansi kwamamitha angu-3000, kanye ne-SmCo magnetic drive (ipompo) endaweni yokushisa ephezulu engu-200 ℃.
6. Ikhanda lokumunca kazibuthe, isihlukanisi kazibuthe, i-magnetic bearing, i-NMR, njll.
