Yav tag los thiab tam sim no ntawm cov neeg hais lus
Hauv kev txhim kho thaum ntxov ntawm tshuab raj hauv hluav taws xob-acoustics, raug rau kev lag luam ntawm kev txhim kho ntawm cov hlau nplaum tas mus li, txav coil tshuab raj tau tag nrho tsav los ntawm electromagnetics. Tom qab Kev Tsov Rog Thoob Ntiaj Teb Thib Ob, cov hlau nplaum muaj zog muaj peev xwm ua tiav tau zoo, thiab cov lus sib pauv hloov pauv ntawm lub tshuab hluav taws xob mus rau cov hlau nplaum ruaj khov. Cov lus no zoo heev txhim kho kev ruaj khov thiab raug tseeb ntawm lub suab. Lub zog coil hom tseem yog txoj kev loj rau cov neeg hais lus niaj hnub kom nrov. Txawm hais tias hom hluav taws xob tsis tshua zoo, nws ua tsis tau zoo, yog li feem ntau siv hauv xov tooj thiab lub taub me me.
Ntxhoo NdFeB
Cov hlau nplaum siv hauv cov hais lus hnub no feem ntau yog ferrites, neodymium nickel cobalt, thiab neodymium iron boron. Neodymium hlau boron hlau nplaum yog cov khoom tseem ceeb ntawm cov tshuab nrov siab kawg, npliag sintered neodymium hlau boron hlau nplaum. Cov khoom sib nqus ntawm sintered NdFeB cov hlau nplaum tau zoo tshaj qhov uas tau lees paub NdFeB cov hlau nplaum, yog li cov suab nrov ntawm tshuab raj siv cov sintered NdFeB cov hlau nplaum zoo dua. Cov yeeb yaj kiab no ua rau neodymium-iron-boron cov hlau nplaum feem ntau siv hauv siab. Lub mloog pob ntseg zoo li no muaj cov suab thib ib zoo, muaj kev hloov pauv tau zoo, cov ntsiab lus zoo, ua suab nrov zoo, thiab muaj suab muaj suab raug.
Thov
Hais txog kev siv, ferrites muaj cov khoom sib nqus tsis tshua zoo thiab yuav tsum muaj qhov ntim kom tau raws li lub zog tsav tsheb ntawm cov neeg hais lus, yog li lawv feem ntau siv ntawm cov neeg hais lus loj dua.
Vim yog qhov yuav tsum tau ua haujlwm ntawm kev ua haujlwm ntawm tus hais lus, tsim nyog NdFeB tuaj yeem xaiv tau raws li qhov kub tsis kam. Piv txwv: N (80 ° C), M (100 ° C), H (120 ° C), SH (150 ° C), UH (180 ° C), EH (200 ° C). Txhua qhov kub muaj cov khoom sib txawv, xws li N38, N40, N45,
Kev ua tau zoo ntawm neodymium-nickel-cobalt hlau nplaum yog nyob nruab nrab ntawm neodymium-iron-boron thiab ferrite, tab sis ob qho no tuaj yeem ua haujlwm ntawm qhov kub siab tshaj 300 ° C, yog li muaj cov kev cai tshwj xeeb rau qhov kub kub, uas tuaj yeem txiav txim siab tau. Tab sis tus nqi yog kuj kim.
Qhov lub cheeb ntawm hais lus ntawm cov hlau nplaum
Thaum peb tham txog ntau npaum li cas ntawm cov lus sib nqus lus, peb txhais tau hais tias lub taub ntawm cov hlau nplaum hauv qhov kub. Piv txwv li, 100 tus mag txhais tau tias txoj kab uas hla ntawm hlau nplaum yog 100 hli.
Cov hlau nplaum ntawm lub tshuab raj tsis loj npaum li sai tau: cov hlau nplaum tau muab faib ua qhov siab ntom ntom, tsis tshua muaj siab
qhov ntom ntom nti, lub zog sib nqus, thiab lub zog sib nqus. Yog tias nws yog qhov tsawg kawg tsis muaj zog magnetism lub zog, tsis muaj qhov sib dhos, nws yuav tsis muaj cov txiaj ntsig zoo, thiab lub ntim loj. Kuj tsis yooj yim.
Rau tib cov khoom siv hlau nplaum, qhov loj dua txoj kab uas hla, qhov loj dua qhov ua kom muaj hlau nplaum ntau dua, qhov loj dua qhov chaw lub dag lub zog, lub zog loj dua lub tshuab raj, lub siab dua ntawm lub siab, thiab zoo dua qhov kev hloov teb.
Yog hais tias qhov tso nyiaj magnetization nws txawv nyob hauv tib qho kev mob, lub zog, kev nkag siab, thiab cov kev hloov pauv ntawm tus hais lus kuj txawv. Yog li ntawd, qhov loj dua ntawm txoj kab uas hla ntawm lub tshuab raj kub, yuav zoo dua.
PS: Feem ntau hais lus, cov hlau nplaum sib txawv ntawm neodymium-iron-boron cov hlau nplaum yog qhov loj dua li ntawm cov ferrite, yog li siv neodymium-iron-boron magnet tsis xav tau lub taub loj. Yog li no, NdFeB feem ntau siv hauv cov lus hais me me, xws li suab tsheb.
Lub cev muaj zog hais lus
Ib tus hais lus yog tus hloov hluav taws xob electroacoustic uas hloov lub zog hluav taws xob ua suab nrov thiab radiates nws rau saum nruab ntug.
Cov hais lus nrov tshaj plaws muaj peb ntu:
1. Kev co lub zog, suav nrog lub khob hliav qab, lub suab sib txuas thiab txhawb kev txhawb nqa, thiab lwm yam.
2. Sib nqus Circuit Court system, nrog rau cov hlau nplaum tas mus li, cov hlau nplaum ib leeg to taub thiab daim teb;
3. Lub kaw lus pabcuam, suav nrog cov phiab sawv ntsug, chaw nres tsheb davhlau ya nyob twg, tus neeg siv lub plhaw thiab plua plav npog, thiab lwm yam
Ua haujlwm txoj haujlwm ntawm hais lus sib nqus Circuit Court
Thaum sib txawv hauv lub zog hluav taws xob xa mus rau lub kauj, lub kauj hlau ua kom muaj zog ntawm
sib cuam tshuam nrog cov khoom sib nqus ntawm cov hlau nplaum; qhov kev sib cuam tshuam no yuav ua rau daim ntawv phaj kom rov ua dua; tib lub sijhawm, vim hais tias hluav taws xob hluav taws xob hloov pauv txhua lub sijhawm, lub kauj ntawm lub tshuab raj yuav txav mus rau tom ntej lossis thim rov qab, Yog li ntawd, daim ntawv phaj ntawm lub tshuab raj yuav ua raws qhov txav, thiab qhov txav yuav hloov qhov ceev ntawm huab cua, thiab ces tsim lub suab. Ntawm no lub luag hauj lwm ntawm cov hlau nplaum yog los pab kev co.
Lub tshuab hluav taws xob tam sim no muab hluav taws xob sib nqus los ntawm lub suab coil. Thaum hloov lub teeb liab hluav taws xob hla, qhov chaw magnetic hloov nws lub zog. Lub sib nqus cov sib nqus ntawm cov hlau nplaum tas mus li hauv qab yog nyiam los ntawm tib poj niam txiv neej thiab rov qab qhov kev sib deev txawv. Vim tias daim ntawv nruas yog txuas nrog lub suab coil, nws txav nce thiab nqis. Qhov kev co ntawm nruas ntawv thawb cov cua kom ua suab.
Lub zog muaj zog ntawm cov hlau nplaum ntau, lub zog sib nqus lub zog sib nqus, qhov sib thooj ntau ntawm cov khoom sib nqus, thiab qhov sib luag ntau ntawm cov khoom sib nqus, muaj ntau qhov rhiab siab thiab ua tau zoo ntawm cov haujlwm sib nqus. Tam sim no, hauv kev sib nqus ntawm kev hais lus ntawm lub suab lus, ferrite lossis neodymium iron boron feem ntau yog siv los ua cov hlau nplaum ruaj khov.
