Kev tswj cov nyiaj ntawm cov hmoov txau yuav tsum tsis lo rau sab nraum qab ntawm cov luam ntawv, thiab kev teeb tsa tus nqi ntawm cov hmoov txau rau cov ntawv luam tawm txawv. Ib qho ntxiv, cov xwm txheej thiab cov ncauj lus tshiab, tsis muaj qhov nraub qaum ntawm cov ntawv luam tawm los tsim cov khoom nplaum, qhov ntau ntawm hmoov yuav tsum tau kho kom ntau li ntau tau, thiaj li ua kom yooj yim rau cov zaj duab xis, txhuam, roj thiab lwm yam kev xaib. xovxwm ua cov txheej txheem ua haujlwm zoo, thiaj li txo qhov nyuaj ntawm kev ua haujlwm thiab khib tus nqi.
Feem ntau, cov plaub xim zoo nkauj luam ntawv hmoov teeb tus nqi 0.3 x 30%, thaj chaw loj hauv cheeb tsam luam ntawv hmoov txheej teeb tus nqi yuav tsum tau nce ntxiv, rau qhov yuav tsum tau luam tawm theem nrab ntawm cov txheej txheem luam ntawv, tus nqi ntawm cov hmoov txheej yuav tsum kom deb li deb raws li muaj peev xwm tswj tau ntawm 0.2 x 20% hauv qab no, luam ntawv kub thiab nyiaj daim npav ntawv, qhov ntau ntawm hmoov txheej nqi yuav tsum tswj hwm ntawm 0.6 x 0.6 x Ntau dua 60%; thaum tus nqi ntawm number case yog tib yam, tus nqi ntawm cov hmoov txau rau daim ntawv dawb ntawm cov xim txho keeb kwm yav dhau los yuav tsum loj dua li cov ntawv dawb lo rau tom qab dawb.
Muaj peb txoj hauv kev ziab zoo nkauj number case, hu ua oxidation conjunctiva kom qhuav, permeable kom qhuav thiab ceev kom qhuav, thiab txhua qhov yuav tsum mus dhau lub sijhawm (feem ntau 4 rau 8 teev) kom tiav cov khoom siv qhuav, yog li cov number case printing txheej txheem kom them tshwj xeeb kom tsis txhob muaj qhov tshwm sim ntawm nplaum ib qho. Thaum qhov tshwm sim ntawm cov nplauv nplaum, yuav tsum tau txais sij hawm nce cov hmoov kom hloov kho, thiab los ntawm kev kho cov ntawv me me ntu cua kiv cua cov txheej txheem, kom cov ntawv zaws ua kom tiav cov ntawv sau.
Tsis tas li ntawd, muaj kev kuaj xyuas qhov loj me ntawm cov tshuaj tsuag hmoov cov lus qhia EFI, uas yog, luam tawm xim tsaus nti (xws li dub) number case xim pawg ntawm cov dej rollerliftlifts, so ntawm cov xim pawg kom tswj tau cov off-pressure xeev, tsaus xim pawg. ib leeg los ntawm lub phaj txhawm rau luam tawm tag nrho. Txij li thaum cov hmoov xau yog xim dawb, qhov loj me ntawm cov hmoov txau tuaj yeem pom pom tseeb, thiab lub qhov ncauj txau tuaj yeem tshawb xyuas qhov txhaws. Cov ntawv xov xwm, ntawv xov xwm rau plaub-xim luam ntawv pov thawj, koj tuaj yeem siv hom no los xyuas seb cov ntawv luam tawm xim pawg ntawm cov roj hmab daim ntaub raug tsoo, yog li kom tsis txhob muaj cov ntawv tawg.
