Isitshixo kwimpumelelo yethu “kuMgangatho oLungileyo woMgangatho, Iindleko eziQhelekileyo kunye neNkonzo eFanelekileyo” kwiiMagnethi zoMhlaba eziRare kwiiMotor zokuSebenzisa iPetroleum kunye neePumpu zeCentrifugal, ke ngoko, siyakwazi ukudibana nemibuzo eyahlukeneyo evela kubathengi abohlukeneyo. Khumbula ukufumana iwebhusayithi yethu ukujonga ulwazi oluninzi kwiimveliso zethu.
Isitshixo kwimpumelelo yethu “kuMveliso oLungileyo woMgangatho oPhezulu, Iindleko eziQhelekileyo kunye neNkonzo eFanelekileyo” ukwenzelaIPetroleum Exploitation Motor Magnets, Iimagnethi zomhlaba ezinqabileyo kwiiPumpu zeCentrifugal, Ngoku kufuneka siqhubeke nokugcina ifilosofi yeshishini "esemgangathweni, eneenkcukacha, esebenzayo" yomoya wenkonzo "onyanisekileyo, onoxanduva, ovelisa izinto ezintsha, sithobele isivumelwano kwaye sithobele isidima, iimpahla zodidi lokuqala kunye nokuphucula inkonzo eyamkelekileyo kubathengi baphesheya kolwandle. .
Uxande Samarium Cobalt umazibuthe, Samarium Cobalt umazibuthe block okanye SmCo umazibuthe uxande luhlobo oluqhelekileyo block emilise SmCo umazibuthe. I-block SmCo umazibuthe inesicelo esibanzi kwiinjini zombane ezikumgangatho ophezulu, izinzwa, iikhoyili zokutshisa, ukudibanisa impompo yemagnethi, njl.njl, ngenxa yeempawu zayo ezithile ngolu hlobo lulandelayo:
1.Amaxabiso omagnetic aphezulu ane-Br ephezulu ukuya kwi-11.7 kG (1.17 T) kunye (BH) nobuninzi obuphezulu ukuya kuma-35 MGOe (275 kJ/m3)
2.Ubushushu bokusebenza obuphezulu kunye nobushushu obuphezulu bokusebenza ukuya kuma-250 ºC ~ 350 ºC
3.Uzinzo olugqwesileyo lwe-thermal kunye ne-coefficient yokushisa ebuyiselwayo ephantsi ukuya ku--0.03 %/ºC ye-Br kunye -0.2%/ºC ye-Hcj
4.Ukumelana nokugqwesa okugqwesileyo kwaye ke akukho nyango luphezulu olufunekayo, ngakumbi kwindawo yokusebenza ye-corrosion ephezulu.
5.Ukuxhathisa okugqwesileyo kwe-demagnetization ngenxa ye-Hcj ephezulu kune-25 kOe (1990 kA/m)
Ngokubanzi iziqwenga ezininzi zoxande iimagnethi ze-SmCo zisikwa ngokusikwa kwesangqa sangaphakathi ukusuka kwibhloko yemagnethi exande ngokuthe ngqo. Ukuba ibhloko ebhityileyo ye-SmCo umazibuthe kwaye ubungakanani bukhulu, umatshini wokusika we-multi-wire usetyenziselwa ukonga iindleko zoomatshini, ukonyusa ukusebenza kakuhle komatshini, ukunciphisa inkunkuma yezinto zemagnethi ukuze kuqinisekiswe ixabiso elingcono kubathengi. Ukuba umlinganiselo wendlela enye okanye ezimbini zikhulu, umzekelo> 60 mm, kufuneka ifune ukugaya kunye ne-EDM (i-electrical discharge machining), ngenxa yemida yomshini wokugaya isangqa sangaphakathi. Ukuba zonke izikhokelo zontathu zinkulu kakhulu, kufuneka ukugaya kuphela.
Kukho umda malunga nemfuneko yobungakanani boxande lweemagnethi zeSmCo ezinengcaciso elandelayo:
Uluhlu lobungakanani obuqhelekileyo: L (Ubude): 1 ~ 160 mm, W (Ububanzi): 0.4 ~ 90 mm, T (Ukutyeba): 0.4 ~ 100 mm
Obona bukhulu bobukhulu: Uxande: L160 x W60 x T50 mm, Isikwere: L90 x W90 x T60 mm
Ubuncinci bobungakanani: L1 x W1 x T0.4 mm
Ubungakanani bendlela yoqhelaniso: Ngaphantsi kwe-80 mm
Ukunyamezela: Ngokuqhelekileyo +/-0.1 mm, Ngokukodwa +/-0.03 mm
Ukuba abathengi bakhetha ubungakanani becala elinye ukuba libe likhulu, amanye amacala amabini kufuneka acuthwe ngokufanelekileyo. Ukuba iindlela ezimbini zikhulu, ubukhulu obubhityileyo kakhulu akuvumelekanga, kuba imagnethi ye-SmCo i-brittle kakhulu kwaye kulula ukuphuka ngexesha lokucoca kunye nokuhlanganisana.Isitshixo kwimpumelelo yethu "Impahla Elungileyo ePhezulu, Iindleko eziQinisekileyo kunye neNkonzo eSebenzayo" yeRare.
