Cov hlab ntshav pov tseg, tseem hu ua lub tshuab nqus cov hlab ntshav, ua lub luag haujlwm tseem ceeb hauv kev kho mob rau kev sau thiab khaws cov ntshav kuaj.Cov txheej txheem tsim khoom ntawm cov raj no yog cov txheej txheem zoo thiab tseem ceeb uas ua kom muaj kev nyab xeeb thiab raug ntawm kev sau ntshav.Hauv tsab xov xwm no, peb yuav ua tib zoo saib cov txheej txheem tsim khoom ntawm cov khoom siv nqus cov hlab ntshav uas siv pov tseg.
Kev tsim cov hlab ntshav pov tseg pib ntawm lub Hoobkas, qhov twg cov khoom siv raw xws li yas, roj hmab stoppers, thiab cov khoom ntxiv tau ua tib zoo xaiv thiab tshuaj xyuas kom zoo.Cov ntaub ntawv no yog tom qab ua tiav thiab molded rau hauv cov duab ntawm lub raj, ua raws li cov lus qhia nruj kom ua tau raws li cov qauv kev lag luam.
Thaum cov hlab ntsha raug tsim, lawv tau ua kom tsis muaj menyuam kom tshem tawm cov kab mob uas muaj peev xwm thiab ua kom muaj kev huv huv ntawm cov ntshav uas tau sau tseg.Cov kauj ruam no yog qhov tseem ceeb hauv kev tiv thaiv kev pheej hmoo ntawm kev kis kab mob thiab tswj kev ncaj ncees ntawm cov qauv.
Tom ntej no, cov hlab yog sib sau ua ke nrog lub tshuab nqus tsev vacuum thiab cov roj hmab stoppers, tsim kom muaj ib qho chaw kaw rau kev sau ntshav.Lub tshuab nqus tsev nyob rau hauv lub raj yuav pab kom nqus cov ntshav mus rau hauv lub raj kom zoo thiab raug yam tsis tas yuav tsum tau ntxiv lub siab los yog phau ntawv suction.
Tom qab sib sau ua ke, cov raj raug tshuaj xyuas rau txhua qhov tsis xws luag lossis tsis zoo uas tuaj yeem cuam tshuam lawv qhov kev ua tau zoo.Kev tswj xyuas kev ua tau zoo yog nyob rau hauv qhov chaw kom ntseeg tau tias tsuas yog cov raj ua tau raws li cov qauv siab tshaj plaws raug xa tawm mus rau kev faib khoom.
Hauv kev xaus, kev tsim cov hlab ntim cov hlab ntshav pov tseg yog cov txheej txheem meej thiab ceev faj uas yuav tsum tau saib xyuas kom meej thiab ua raws li cov qauv nruj.Cov hlab no ua lub luag haujlwm tseem ceeb hauv kev kho mob, ua kom muaj kev nyab xeeb thiab raug sau cov ntshav kuaj rau kev kuaj mob.Los ntawm kev nkag siab txog cov txheej txheem tsim cov hlab ntshav pov tseg, peb tuaj yeem txaus siab rau kev siv zog thiab kev saib xyuas uas mus rau hauv kev tsim cov khoom siv kho mob tseem ceeb no.
