Sib Nqus particle xeem - ib tug zoo txoj kev uas yuav ntes cov khoom tsis xws luag

Thaum lub caij, muaj ntau ntau yam txoj kev kom paub tseeb lub xeev ntawm cov chaw uas muaj cov khoom ua los ntawm ferromagnetic cov ntaub ntawv. Lawv pab txiav txim seb tus zoo ntawm cov khoom. Ib tug ntawm cov pov thawj thiab lees paub tias txoj kev yog magnetic particle soj ntsuam. Qhov no txoj kev yuav ua rau nws tau kom paub tias cov sib txawv ntawm cov tsis xws luag - tej kab nrib pleb, flaws nyob rau hauv cov pob qij txha welded thiab lwm yam.

Hauj lwm ntawm txoj kev

Sib Nqus particle xeem no yog tsim los sim sib txawv khoom, los ntawm kev loj me me HVD khoom, xws li tag nrho cov hom ntawm cov ntaub ntawv. Nws yog ib qho zoo txoj kev ua pov thawj. Nyob rau hauv cov ntaub ntawv no, tej yam ntxwv ntawm cov khoom yuav tsum tau tsim magnetization. Nws yog tsim nyog rau cov tsim ntawm lub teb los mus tshem tawm tsis xws luag ntawm cov khoom. Qhov no yuav pab txhawb lub attraction hais ntawm ib tug tshwj xeeb hmoov. Rau ntau dua lub caij nyoog ntawm kev nrhiav flaws yuav tsum muaj lawv cov dav hlau ntawm txoj cai ces kaum rau lub khiav ntawm magnetic flux. Qhov no yog ib qho tseem ceeb heev prerequisite. Nyob rau hauv cov ntaub ntawv ntawm ib tug yuav txo tau ntawm hais tias lub txo lub peev xwm mus ntes tsis xws luag.

feature ntawm tus txheej txheem

Sib Nqus particle soj ntsuam txoj kev nyob rau tej thaj chaw ntawm cov khoom ntawm cov khoom. Lawv muaj yog ib qho tseem ceeb nyob rau hauv cov ntaub ntawv no. Cov muaj xws li:

• Sib Nqus induction.
• Lub coercive quab yuam.
• Qhov seem magnetization.
• Lub xub ntiag ntawm roughness rau ntawm qhov chaw ntawm cov khoom.
• Feem ntau cov sib nqus permeability.
• Lub illumination nto ntawm qhov khoom.
• Lub magnetic teb siv thiab nws qhov chaw nyob txheeb ze rau lub dav hlau ntawm lub defect.

kheej ntawm daim ntawv thov

Hais tias txoj kev no yog siv nyob rau hauv ntau yam industries. Yeej, magnetic particle soj ntsuam no yog siv nyob rau hauv mechanical engineering, shipbuilding thiab tsheb industries. Tsis tas li ntawd nws yog siv nyob rau hauv cov roj thiab cov nkev kev lag luam. Sib Nqus particle soj ntsuam (GOST 21105-87) yog yus muaj los ntawm siab productivity, rhiab heev, uas tso cai rau mus qhia muaj cov tsis xws luag thaum lub sij hawm ntawm lawv cov tshwm sim. Qhov no yog nws tseem ceeb tej khoom vaj tse.

Sib Nqus particle soj ntsuam: cov qauv kauj ruam

1. Kev npaj ntawm cov khoom rau kev soj ntsuam. Ua cleansing nto los ntawm av, xeb thiab ntau yam roj. Yog hais tias qhov chaw ntawm cov khoom yog tsaus, lub magnetic hmoov yog tsis pom. Nyob rau hauv cov ntaub ntawv no, qhov khoom ib tug txheej ntawm dawb xim.
2. Omagnitichivanie khoom. Qhov no yog lub ntsiab theem ntawm kev tswj. Nws yog ib qho tseem ceeb los mus xaiv tus muaj txoj cai txoj kev magnetization. Qhov no yuav txiav txim qhov rhiab heev thiab qhov yuav tshwm ntawm kev nrhiav flaws.
3. Cov txheej nto ntawm cov khoom magnet hmoov los yog ib ncua kev kawm. Qhov no kauj ruam yuav tsum tau txiav txim siab kho mob. Thaum ua ntawv thov cov slurry khoom yog dipped rau hauv lub thawv nrog lub kua los yog, ntau technologically, ncuav lub yam khoom los ntawm lub hose nyob rau hauv ib tug tsis muaj zog siab. Siv ib tug qhuav hmoov yog yus muaj los ntawm nws daim ntawv thov ntawm cov huab cua txaus.
4. Kev soj ntsuam ntawm cov khoom. Nyeem drawings thiab muab qhab nia. Dig muag, los tshawb xyuas lub yam khoom los yog nrog kho qhov muag pab kiag li lawm yuav tsum maub los tom qab daim ntawv thov thiab tshem tawm ntawm lub magnetic substance. Rau presorting tsim nyog kev sib piv nrog rau cov muaj cov duab ntawm txawv tsis xws luag.
5. Demagnetization thiab tshem tawm cov seem hais tias qhov taw qhia. Qhov no yog zaum kawg theem. Nyob rau hauv cov ntaub ntawv no, muaj ob txoj kev xaiv demagnetization:

• Qhov zoo tshaj yog qhov kev siv cua sov rau hauv tsab xov xwm mus rau ib tug kub ntawm lub Curie point. Yog li muaj yog ib tug tsis sib nqus ntawm cov khoom. Txawm li cas los, qhov no txoj kev yog siv heev tsis tshua muaj. Qhov no yog vim lub fact tias tus cua kub tej zaum yuav tshwm sim hloov nyob rau hauv tus neeg kho tshuab thaj chaw ntawm cov khoom khoom, uas nyob rau hauv ntau mob yog tsis tsim nyog.
• Qhov thib ob hom yog raws li nyob rau hauv kev demagnetization nthuav dav los ntawm txoj kev lub alternating magnetic teb nrog ib tug amplitude uas yuav tsum tau txo uniformly los ntawm tus taw tes ib tug tej yam siab tshaj plaws rau zero. Qhov no txoj kev yog nrov dua. Tus zaus ntawm hais tias thov magnetic teb nyob rau qhov luaj li cas thiab zoo ntawm lub kuaj yam khoom.
