Ivacuum yomkhenkce{0}}ukomisa kuxhomekeke kwimeko yokufunxa ephezulu ukuze kuqatshelwe ukuthotywa ngokuthe ngqo kweekristale zomkhenkce ngaphakathi kwemathiriyeli. Emva kokuba izixhobo zineendawo zokuvuza komoya, umoya wangaphandle ungena ngokuqhubekayo kwigumbi lokumisa. Inkqubo yokufunxa kufuneka iqhubeke isebenza kumthwalo ophezulu ukugcina ixabiso levacuum ekujoliswe kuyo. Ivacuum engonelanga iya kuthoba isantya se-sublimation ngokucacileyo. Izinto eziphathekayo ziyakwazi ukunyibilika kwendawo, i-shrinkage kunye nokudilika, okukhokelela ekuthungeni kwemveliso engagqibekanga kunye nokwandisa kakhulu izinga lokwaliwa. Kwiimeko ezinzima, yonke ibhetshi yemathiriyeli ekrwada iya kuchithwa.
Uninzi lweentsilelo zokuvuza kwevacuum zivela kwinkqubo yokutywina. Ezona ndawo zisesichengeni zibandakanya umcu wokutywina wegumbi lokomisa ucango lwe-silicone, i-gaskets yokutywina ye-flange, i-vacuum valve rings, i-shaft eguquguqukayo yokutywinwa kweendlela zokuguqula. La macandelo e-polymer yerabha asebenza ngokutshintshanayo phantsi kobushushu obuphantsi, ubushushu obuqhelekileyo kunye noxinzelelo lokutshintsha indawo ixesha elide. Emva kokusebenza ixesha elide -, iingxaki ezinjengokuqina, ukuqhekeka, ukuguqulwa, ukunamathela komphezulu weentsalela zezinto ziya kuvela kancinci. Izikhewu ezincinci ezenziwe zezi ziphene ziba yimijelo yokungena emoyeni.
Amashishini kufuneka enze imijikelo yokuhlolwa rhoqo kumacandelo okutywinwa. Phambi kwebhetshi nganye yemveliso, abaqhubi kufuneka bajonge ukuba ingaba umcu wokutywina ucango ukwimeko entle, ucoce inkunkuma yenkunkuma, igrisi kunye nezinye iintsalela ezincanyathiselwe kumphezulu. Imiba yangaphandle ebambeke phakathi komphezulu wokutywina kunye nomtya werabha uya kubangela ukucinezelwa okungaphelelanga kunye nokuhlenga okusisigxina komcu wokutywina. Ukuba ukuqina, iintanda kunye nokulahleka kwe-elastic kufunyenwe, buyisela izincedisi ngexesha endaweni yokuqhubeka nemveliso.
Kwisixhobo esine-vacuum yokuhla okucacileyo, umsebenzi wokufumanisa ukuvuza okusemgangathweni kufuneka wenziwe. Iindlela zokubona eziqhelekileyo ziquka uvavanyo lwe-vacuum yokubamba i-static, ukuhlolwa kwesitshizi sokuvuza. Emva kokuba indawo yokomisa{2}}ivaliwe kwaye impontshelwe kwindawo ekujoliswe kuyo, cima inkqubo yokufunxa kwaye urekhode isantya sokunyuka kwevacuum. Ukuba ukunyuka koxinzelelo kudlula umgangatho osemgangathweni, kubonisa ukuba kukho ukuvuza okucacileyo. Emva koko ugxininise ekujongeni isakhelo socango, uxhulumaniso ngalunye lwe-flange, iindawo zevalve. Kuyafaneleka ukuba uqaphele ukuba amandla amaninzi xa uvala umnyango uya kubangela ukuguqulwa okusisigxina komgca wokutywina; amandla okubamba afanelekileyo kufuneka agcinwe ngokweemfuno zesixhobo.
Iifektri ezininzi zithatha indawo yezixhobo kuphela emva kokuvuza okukhulu, okuzisa umngcipheko wokuguquguquka komgangatho kwimveliso. Ukugcinwa kwemihla ngemihla kunokwandisa ubomi benkonzo yeendawo zokutywina. Kuphephe ukusebenzisa izinto ezityiwayo zokucoca ukukhuhla amatywina erabha; thintela unxibelelwano oluthe ngqo-nexesha elide kunye negrisi kunye nejusi yezinto ezineasidi. Kwisixhobo sokuvala-ixesha elide, gcina ucango luvuliwe kancinci ukunqanda-uxinzelelo lwexesha elide ukuguga komtya wokutywina.
Ulawulo olulungileyo lokutywina lunokugcina usetyenziso lwevacuum ezinzileyo yesomisi esingumkhenkce, isiqinisekiso somjikelo ongaguqukiyo wokomisa kwibhetshi nganye yemathiriyeli, ukulawula iyunithi yokusetyenziswa kwamandla phakathi koluhlu olulindelekileyo, kunye nokunciphisa ilahleko yemveliso ngokungeyomfuneko kumkhenkce{0}amashishini okulungisa ukutya okomileyo.
