Izakhiwo zemikhiqizo ehlukahlukene ye-liquid azifani.Enqubweni yokugcwalisa, ukuze kugcinwe izici zemikhiqizo zingashintshiwe, izindlela zokugcwalisa ezihlukene kufanele zisetshenziswe.Umshini ojwayelekile wokugcwalisa uketshezi uvame ukusebenzisa izindlela zokugcwalisa ezilandelayo.
1. Indlela yokucindezela komkhathi
Indlela yengcindezi ye-atmospheric yaziwa nangokuthi indlela ye-gravity emsulwa, okungukuthi, ngaphansi kwengcindezi yomoya, uketshezi oluwuketshezi lugelezela esitsheni sokupakisha ngesisindo somuntu siqu.Iningi loketshezi olugelezayo lwamahhala lugcwaliswa ngale ndlela, njengamanzi, iwayini lezithelo, ubisi, isoso yesoya, uviniga nokunye.Njengomshini wokugcwalisa inkomishi yokuwasha amanzi/yogathi:
2. Indlela ye-Isobaric
Indlela ye-Isobaric yaziwa nangokuthi indlela yokugcwalisa amandla adonsela phansi okucindezelayo, okungukuthi, ngaphansi kwesimo esingaphezu kwengcindezi yasemkhathini, qala ngokufutha isitsha sokupakisha ukuze wenze ingcindezi efanayo nebhokisi lokugcina uketshezi, bese ugelezela esitsheni sokupakisha ngokuncika isisindo somzimba wezinto zokugcwalisa.Le ndlela isetshenziswa kakhulu ekugcwaliseni iziphuzo ezifakwa umoya, njengobhiya, i-soda newayini elicwebezelayo.Le ndlela yokugcwalisa inganciphisa ukulahlekelwa kwe-carbon dioxide kulolu hlobo lwemikhiqizo, futhi ivimbele amagwebu amaningi ohlelweni lokugcwalisa ukuthinta ikhwalithi yomkhiqizo nokunemba komthamo.
3. Indlela ye-vacuum
Indlela yokugcwalisa i-vacuum yenziwa ngaphansi kwesimo esingaphansi kwengcindezi yasemkhathini, engenziwa ngezindlela ezimbili.
a.Uhlobo lwe-vacuum yengcindezi ehlukile
Okusho ukuthi, lapho ithangi lokugcina uketshezi lingaphansi kwengcindezi evamile, isitsha sokupakisha kuphela esimpontshwayo ukuze sakhe i-vacuum, futhi uketshezi oluwuketshezi lugeleza ngomehluko wengcindezi phakathi kwethangi lokugcina uketshezi kanye nesitsha okufanele sigcwaliswe.Le ndlela isetshenziswa kakhulu eChina.We chantecpack sethula ifomu lethu le-VFFS lemayonesi emile ligcwalise umshini wokupakisha wesikhwama onjengangezansi:
b.Ivacuum yamandla adonsela phansi
Okusho ukuthi, isiqukathi sikwivacuum, futhi isitsha sokupakisha siyampontshwa kuqala ukuze kwakheke i-vacuum elingana naleyo esitsheni, bese uketshezi oluwuketshezi lugelezela esitsheni sokupakisha ngesisindo saso.Ngenxa yesakhiwo sayo esiyinkimbinkimbi, ayivamile ukusetshenziswa eChina.Ukugcwaliswa kwe-vacuum kunezinhlobonhlobo zezinhlelo zokusebenza.Akufanele kuphela ukugcwalisa izinto eziwuketshezi nge-viscosity ephakeme, njengamafutha nesiraphu, kodwa futhi kufanelekile ukugcwalisa izinto eziwuketshezi eziqukethe amavithamini, njengejusi yemifino kanye nejusi yezithelo.Ukwakhiwa kwe-vacuum ebhodleleni kusho ukuthi ukuxhumana phakathi kwezinto eziwuketshezi nomoya kuyancishiswa futhi impilo yeshalofu yemikhiqizo iyandiswa.Ukugcwaliswa kwe-vacuum akufanelekile ukugcwalisa izinto ezinobuthi, njengezibulala-zinambuzane, ukunciphisa izindleko Ukuchitheka kwamagesi anobuthi kungathuthukisa izimo zezolimo.
