Bar hlau nplaum tuaj yeem faib rau ib ntawm ob hom: kev nyob ruaj khov thiab ib ntus. Cov hlau nplaum tas mus li yog ib txwm nyob hauv "ntawm" txoj haujlwm; Ntawd yog, lawv cov chaw sib nqus yog ib txwm ua haujlwm thiab tam sim no. Cov hlau nplaum ib ntus yog cov khoom siv uas ua kom cov magnetized thaum ua raws li los ntawm ib qho kev sib nqus. Tej zaum koj siv hlau nplaum ua si nrog koj niam cov plaub mos mos ua menyuam yaus. Nco ntsoov tias koj tuaj yeem siv cov plaub hau sib txuas nrog cov hlau nplaum txuas rau cov plaub hau thib ob? Yog vim tias thawj cov plaub hau tau dhau los ua cov hlau nplaum ib ntus, ua tsaug rau lub zog ntawm daim teb sib nqus puag ncig nws. Electromagnets yog hom hlau nplaum ib ntus uas dhau los ua "nquag" tsuas yog thaum muaj hluav taws xob txuas ntxiv los ntawm lawv tsim cov sib nqus.
Dab tsi yog alnico hlau nplaum?
Ntau cov hlau nplaum hnub no raug xa mus rau "Alnico" cov hlau nplaum, ib lub npe tau muab los ntawm cov khoom siv hlau los ntawm cov khoom siv ntawm cov hlau uas lawv tau ua: txhuas, npib tsib xee thiab cobalt. Alnico Hlau nplaum yog feem ntau yog ib qho bar- lossis horseshoe-puab. Nyob rau hauv lub hlau nplaum barrat, rov qab yog nyob ntawm qhov xaus ntawm qhov bar, thaum nyob rau hauv ib tug nees horseshoe hlau nplaum, lub sij hawm nyob rau hauv ib tug horseshoe hlau nplaum, thaum nyob ze sib luag, ntawm qhov xaus ntawm horseshoe. Bar hlau nplaum kuj tseem yuav tsim los ntawm cov ntaub ntawv tsis tshua muaj av - neodymium lossis samarium cobalt. Ob lub tiaj-tog kab hlau nplaum thiab hloov bar magnet hom hlauet muaj; Hom uas yog siv feem ntau yog nyob ntawm daim ntawv thov uas cov hlau nplaum yog siv.
Kuv cov hlau nplaum tsoo ob. Nws puas tseem ua haujlwm?
Tsuas yog qee qhov kev poob ntawm cov hlauetism ua tau raws li lub ntsej muag tawg, cov hlau nplaum uas tau tawg ob qho, txhua tus yuav yog ib nrab li qub, unbroken hlau nplaum.
Txiav txim siab ncej
Tsis yog txhua tus hlau nplaum yog cim nrog "N" thiab "S" los tsim cov qauv tsim. Txhawm rau txiav txim cov ncej ntawm cov hlau nplaum bar-hom hlau nplaum, tso lub cim nyob ze cov hlau nplaum thiab saib rab koob; Qhov kawg uas ib txwm taw rau lub ntiaj teb sab qaum teb sab qaum teb yuav viav vias ib puag ncig mus rau sab qab teb ncej ntawm cov hlau nplaum ntawm cov hlau nplaum. Qhov no yog vim tias cov hlau nplaum yog ze rau lub koob qhia, ua rau muaj kev nyiam ua kom muaj zog dua lub ntiaj teb tus kheej sib nqus. Yog tias koj tsis muaj lub koob qhia, koj tuaj yeem ntab cov kab hauv ib lub taub ntim dej. Lub hlau nplaum yuav maj mam tig kom tig mus kom txog thaum nws North Ncej yog mus raws li lub ntiaj teb qhov tseeb sab qaum teb. Tsis muaj dej? Koj tuaj yeem ua tiav tib yam txiaj ntsig los ntawm kev ncua cov hlau nplaum ntawm nws qhov chaw nrog txoj hlua, cia nws txav thiab tig dawb.
Hlau nplaum Dag
Bar hlau nplaum yog ntsuas raws li peb ntsuas: Realual induction (br), uas qhia txog lub zog muaj peev xwm ntawm cov hlau nplaum; Ntau lub zog (BHMAX), uas ntsuas lub zog sib nqus lub zog ntawm cov khoom siv sib nqus; Thiab courcive quab yuam (HC), uas qhia tias nws yuav nyuaj npaum li cas nws yuav demagnetize lub hlau nplaum.
Lub zog quab yuam muaj zog tshaj plaws ntawm cov hlau nplaum nyob qhov twg?
Lub zog sib nqus ntawm cov hlau nplaum yog qhov siab tshaj plaws lossis feem ntau mloog ntawm tus ncej kawg thiab tsis muaj zog nyob hauv plawv ntawm tus ncej thiab lub hlau nplaum lub chaw. Lub zog yog sib npaug ntawm tus ncej. Yog tias koj muaj kev nkag tau rau cov ntawv pov tseg hlau, sim qhov no: tso koj cov hlau nplaum ntawm lub tiaj tiaj, ntshiab. Tam sim no sprinkle hlau filings nyob ib ncig ntawm nws. Cov ntawv thov yuav tsiv mus rau txoj haujlwm uas yog qhov pom ntawm koj lub zog uas muaj zog tshaj, kis sib txawv raws li lub teb tsis muaj zog.
Khaws Cia Cov Hlau nplaum
Txhawm rau khaws cov hlau nplaum ua haujlwm ntawm lawv qhov zoo tshaj plaws, kev saib xyuas yuav tsum tau coj los xyuas kom lawv tau khaws cia zoo.
Ceevfaj tsis txhob cia cov hlau nplaum ua txuas rau ib leeg; Kuj tseem ceev faj kom tsis txhob cia cov hlau nplaum sib tsoo sib tsoo thaum muab tso rau hauv cia. Kev sib tsoo tuaj yeem ua rau kev puas tsuaj rau cov hlau nplaum thiab tseem tuaj yeem ua rau raug mob rau cov ntiv tes uas los ntawm ob lub zog nyiam nyiam cov hlau nplaum
Xaiv lub taub ntim kaw rau koj cov hlau nplaum kom tiv thaiv cov khib nyiab me me los ntawm kev nyiam ua cov hlau nplaum.
Khaws cov hlau nplaum hauv cov khoom lag luam txaus siab; Sijhawm dhau sijhawm, qee cov hlau nplaum uas tau khaws cia hauv cov haujlwm rov ua haujlwm tuaj yeem poob lawv lub zog.
Khaws Alnico Hlau nplaum nrog "Feeters," daim hlau siv los txuas cov ncej ntawm ntau cov hlau nplaum; Cov neeg ua haujlwm pab tiv thaiv cov hlau nplaum los ua cov demagnetized sijhawm dhau sijhawm.
Khaws cia ntim khoom kom deb ntawm cov khoos phis tawm, VCRS, daim npav rho nyiaj thiab cov khoom siv lossis xov xwm uas muaj sib nqus lossis microchaips.
Kuj tseem cia cov hlau nplaum muaj zog nyob deb ntawm txhua qhov chaw uas tuaj yeem tuaj xyuas los ntawm cov tib neeg uas tuaj yeem sib nqus tau vim yog cov pacemaker rau malfunction.
