Lub hlau uas txuas nrog ntug feem ntau kav ntev npaum li cas?
Lub neej ua haujlwm ntawm cov hlau txuas ntug nyob ntawm ntau yam xws li cov khoom siv, qhov zoo ntawm cov txheej txheem tsim khoom, qhov tsis zoo ntawm nws tus qauv tsim, cov xwm txheej ib puag ncig ua haujlwm xws li lub voj voog siab thiab qhov kub thiab txias hloov pauv cuam tshuam rau lub neej qaug zog. Txhawm rau kom ua tau ntev tshaj plaws, ua raws li cov lus qhia teeb tsa kom raug thiab cov txheej txheem txij nkawm tsis tu ncua.
Puas muaj lwm txoj hauv kev rau kev siv cov hlau txuas ntug hauv kuv daim ntawv thov?
Muaj ntau txoj kev xaiv nyob ntawm seb koj xav tau dab tsi rau daim ntawv thov. Qee txoj kev xaiv uas siv ntau suav nrog cov ntsaws ruaj ruaj diaphragm (rau cov cuab yeej ntsuas siab), cov ntsaws ruaj ruaj uas muaj caij nplooj ntoos hlav (rau kev siv foob rotary), thiab cov ntsaws ruaj ruaj hydraulic/pneumatic piston lossis rod. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum soj ntsuam qhov chaw ua haujlwm, qhov yuav tsum tau ua kom txav mus los, thiab kev tsim qauv tag nrho ua ntej xaiv lwm txoj hauv kev siv tshuab.
Puas muaj peev xwm hloov kho tau rau cov hlau txuas ntug?
Yog, cov hlau txuas ntug tuaj yeem hloov kho raws li qhov xav tau ntawm daim ntawv thov tshwj xeeb, xws li kev xaiv cov khoom siv, cov qauv ntawm lub bellow (kev suav convolution thiab qhov siab), kev teeb tsa flanges kawg, thiab hom foob. Ua haujlwm nrog lub chaw tsim khoom lossis pab pawg engineering uas muaj npe nrov uas tshwj xeeb hauv kev daws teeb meem kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws thiab cov khoom siv sib xws rau koj daim ntawv thov tshwj xeeb.
Xaus lus
Xaus lus, cov hlau txuas ntug yog cov kws tshaj lij daws teeb meem zoo tshaj plaws rau kev daws teeb meem hauv kev sib khi thiab kev ywj pheej. Los ntawm kev muab ib puag ncig kaw hermetically, kev ntseeg siab zoo heev, kev hloov kho tau, thiab lub neej ntev zoo kawg nkaus, cov khoom siv ntse no sawv ntsug npaj txhij los daws koj cov ntawv thov engineering uas xav tau tshaj plaws. Tsis txhob cia cov yam txwv tsis pub cuam tshuam koj txoj kev xav tsim - txais yuav cov peev xwm ntawm cov hlau txuas ntug thiab paub txog kev hloov pauv hnub no!
