Cov khoom ntawm cov hlau nplaum tau paub rau tib neeg lub sijhawm ntev, tab sis ua tsaug rau txoj kev loj hlob ntawm kev lag luam, lawv tau dav siv nyob rau thaum xaus ntawm lub xyoo pua 19th. Nrog rau kev ua haujlwm ntau lawm, cov ntaub ntawv ferrimagnetic kuj tseem siv hauv lub neej txhua hnub. Ib qho nthuav, thiab tseem ceeb tshaj, txoj kev muaj txiaj ntsig yog kev tshawb nrhiav cov khoom siv hlau. Ua ntej nrhiav seb qhov kev tshawb nrhiav hlau nplaum yog dab tsi, koj yuav tsum paub nws cov yam ntxwv tseem ceeb thiab cov khoom.
Cov khoom tsim tawm
Cov hlau nplaum uas siv tau feem ntau yog cov khoom siv dag zog. Cov ntaub ntawv ntuj, tshwj xeeb tshaj yog cov hlau nplaum hlau, tsis muaj cov khoom yuav tsum tau ua. Lawv muaj qhov ntsuas me me ntawm lub zog tearing, susceptibility rau kev puas tsuaj sai vim yog kev ntxhov siab ntawm kev siv tshuab. Yog li ntawd, rau cov hom phiaj kev lag luam, ferrites feem ntau yog siv, uas tau muab tso rau hauv ib qho chaw sib nqus thaum lub sijhawm tsim khoom. Lawv lub neej kev pabcuam tuaj yeem suav tau hauv kaum xyoo, thiab tsis muaj kev ua haujlwm poob haujlwm.
Tsis zoo li kev lag luam tsim, kev tsim cov hlau nplaum hauv tsev yog qhov yooj yim. Vim lawv qhov me me, lawv feem ntau siv rau lawv cov khoom siv. Neodymium alloy - N-Fe-B. Txhawm rau txhim kho cov neeg kho tshuab lub zog thiab txo tus nqi, cov hlau thiab boron ntxiv rau cov khoom muaj pes tsawg leeg. Qhov tshwm sim yog cov hlau nplaum neodymium, qhov kev tshawb nrhiav uas tseem tab tom tshwm sim.
Lawv qhov dav dav:
- Furniture kev lag luam - qhov rooj stoppers.
- Kev ruaj ntseg - ua ke nrog cov sensors.
- Xaiv ntawm angular tshaj tawm lossis angular txoj haujlwm - siv ua ke nrog Hall sensor.
- Nyob rau hauv kev tshawb nrhiav thiab archaeological expeditions.
Rau kev siv ntiag tug, kuj tseem muaj qhov nthuav dav ntxiv. Hauv cov cheeb tsam uas muaj keeb kwm yav dhau los nplua nuj, koj tuaj yeem ua cov hlau nplaum tshawb nrhiav nrog koj tus kheej tes thiab koom nrog kev siv archaeology.
ntsuas kev nyab xeeb
Tsis muaj coob tus neeg paub tias qee cov cai yuav tsum ua raws li kev ua haujlwm nrog cov hlau nplaum. Feem ntau, cov qauv loj muaj qhov zoo uas tuaj yeem ua mob rau tib neeg thiab tsheb.
Yog li ntawd, cov kev ntsuas kev nyab xeeb hauv qab no yuav tsum ua raws:
- Npaj lub thawv tshwj xeeb, cov khoom uas tsis yog hlau nplaum. Nws tuaj yeem yog ntoo lossis tuab-walled polymer. Tso daim ntawv ceeb toom rau saum npoo.
- Rau kev ua haujlwm ib txwm ntawm cov khoom siv hluav taws xob, qhov tsawg kawg nkaus ntawm cov hlau nplaum yuav tsum yog 10-20 cm.
- Kev quab yuam muaj qhov tsis zoo rau kev ua haujlwm ntawm lub tshuab pacemaker.
- Qhov chaw nruab nrab ntawm cov hlau nplaum thiabhlau yuav tsum dawb. Kev ua tsis tau li ntawd yuav ua rau raug mob vim yog ceg ceg ceg.
Tsim
Rau qhov kev cia siab, nws yuav tsum ua tib zoo xav txog tus qauv tsim thiab coj mus rau hauv tus account qhov tshwj xeeb ntawm kev ua haujlwm. Nws tsis txaus coj cov khoom tiav, khi rau txoj hlua ruaj khov thiab mus rau tom teb nrhiav cov khoom muaj nqis.
Yog tias koj yuav tsum ua cov hlau nplaum tshawb nrhiav nrog koj tus kheej tes, ces kos duab thawj zaug. Nws qhia tag nrho qhov ntev ntawm txhua lub ntsiab lus, cov khoom siv thiab cov txheej txheem ntawm lawv lub rooj sib txoos. Los ntawm kev ua raws li cov kauj ruam yooj yim no, ntau yam yuam kev tuaj yeem zam tau. Piv txwv li - yog tias ib feem ntawm cov hlau nplaum yuav tsum tau qhib, ces tsis txhob coj mus rau hauv tus account tus txheej txheem ntawm kev txuas nws mus rau lub casing tiv thaiv.
Qhov kev xaiv zoo tshaj plaws - lub plhaub tiv thaiv tag rov ua cov khoom zoo. Hauv qhov no, qhov kev pheej hmoo ntawm kev puas tsuaj thaum caij tsheb thauj mus los lossis thaum lub sijhawm tshawb nrhiav raug txo.
Ua ntej kev tsim khoom, nws yog qhov tsim nyog los txiav txim siab cov yam ntxwv, uas ncaj qha nyob ntawm qhov loj me.
Parameters
Nrog rau qhov nce hauv qhov ntev ntawm cov hlau nplaum, nws qhov kev ua tau zoo nce. Nyob ntawm txoj haujlwm, koj yuav tsum ua tib zoo xaiv, raws li tus nqi ntawm ntau yam qauv tuaj yeem nyob ntawm 30 txog 300 las.
tuav yuag, kg |
Magnet hnyav, kg |
Dab, mm |
siab, mm |
| 300 | 1,2 | 96 | 18 |

Tab sis dab tsi yog qhov kev tshawb nrhiav hlau nplaum yam tsis muaj iav?
Lub cev thiab nqa khoom
Lub plhaub tiv thaiv yog ua los ntawm cov khoom siv ruaj khov. Qhov kev xaiv zoo tshaj plaws yog tig lub steel billet tom qab galvanizing. Cov khoom zoo li no yuav dhau los ua kev tiv thaiv kev tiv thaiv kev puas tsuaj, thiab ua tsaug rau cov txheej txheem saum npoo, nws yuav tsis corrode rau lub sijhawm ntev.
Txoj kev kho cov hlau nplaum hauv vaj tse tuaj yeem sib txawv. Tab sis qhov nrov tshaj plaws thiab siv tau yog:
- Kev tsim cov qauv kaw nrog lub hau ntsia hlau. Nws nruj nreem ua kom tsis txhob ntshai ntawm qhov teeb meem ntawm dej, txawm tias dej hiav txwv.
- Kho nrog epoxy kua nplaum.
Koj tuaj yeem tsim cov hlau nplaum tshawb nrhiav nrog koj tus kheej tes hauv lwm txoj hauv kev. Qhov tseem ceeb tshaj plaws yog saib xyuas kev nyab xeeb thiab saib xyuas kev ntseeg tau ntawm tag nrho cov qauv.
Rau nqa, feem ntau yog siv txoj hlua ruaj khov, lub zog tawg uas yuav tsum yog tsawg kawg peb zaug ntawm qhov hnyav ntawm qhov tuav.
siv tswv yim
Tab sis dab tsi yog qhov kev tshawb nrhiav hlau nplaum yam tsis muaj kev pom zoo? Ua tsaug rau nws qhov tshwj xeebcov khoom, nws tuaj yeem siv tau qhov twg cov khoom siv hlau tsis zoo - hauv cov dej hauv dej. Nrog kev txawj ntse, koj tuaj yeem ua tib zoo tshawb xyuas thaj tsam loj ntawm tus dej hauv qab hauv ib hnub. Muab cov keeb kwm yav dhau los loj heev ntawm yuav luag txhua cheeb tsam ntawm lub tebchaws, muaj tseeb tias yuav yog ib daim ntawv luam tshwj xeeb los ntawm ntau pua xyoo dhau los.
Tab sis tsis txhob ua rau koj tus kheej nrog kev xav ntawm kev nplua nuj sai sai - qhov kev tshawb pom ntawm cov hlau nplaum tshawb nrhiav muaj ntau yam thiab tsis yog ib txwm muaj txiaj ntsig. Nws yog ib qho tsim nyog yuav tsum tau shovel lub qhov ncauj ntawm tus dej kom pom ib yam dab tsi tsim nyog mloog. Yog li ntawd, ua ntej pib qhov kev ntoj ke mus ncig me me, nws raug nquahu kom paub koj tus kheej nrog keeb kwm ntawm cheeb tsam txhawm rau txhawm rau txhawm rau ua kom muaj kev vam meej "catch".
