I-vacuum emulsifiers idlala indima ebalulekileyo kwinkqubo yokuxuba yezixhobo zoshishino, ngokukodwa ekuxubeni okuqinileyo-ulwelo, ukuxutywa kwe-liquid-liquid, i-oil-water emulsification, i-dispersion kunye ne-homogenization, ukugaya i-shear kunye neminye imiba. Isizathu sokuba ubizwe ngokuba ngumatshini we-emulsifying kungenxa yokuba unokufikelela kwisiphumo se-emulsifying. I-emulsion yamanzi ye-oyile yenziwa emva kokuba i-medium-phase medium ixutywe ngokupheleleyo, kwaye ihlukaniswe kwiinkqubo ezimbini: amanzi-oyile okanye amanzi-oyile. Ukufezekisa i-emulsification, kukho ubuncinane iimfuno ezimbini:
Okokuqala, ukusika komatshini kunempembelelo enamandla yokusabalalisa. Isigaba samanzi kunye nesigaba seoli kwi-fluid medium sinqunywe kwiincinci ezincinci ngexesha elifanayo, kwaye emva koko zidibaniswe ngexesha lokungena kunye nokuxuba ukwenza i-emulsion.
Okwesibini, i-emulsifier efanelekileyo isebenza njengebhulorho yomlamli phakathi kweoli kunye neamolekyu zamanzi. Ngokusebenzisa isenzo somrhumo wombane kunye ne-intermolecular force, i-emulsion yomxube we-oyile-amanzi inokugcinwa ngokuzinzileyo ngexesha elifunekayo.
Amandla esenzo sokucheba se-emulsifier sichaphazela ngokuthe ngqo ukucolwa. Ngokuhlalutya, kukho ubukhulu becala ubukhali, ubunzima, i-gap ye-stator, isantya esihambelanayo samacandelo amabini okusika kunye nobukhulu obuvumelekileyo be-particle, njl. Kwiimeko eziqhelekileyo, ubukhali kunye nobunzima be-blade , ukuchithwa kwe-stator kunye nesiseko esivumelekileyo. amaxabiso axhomekeke kakhulu kubungakanani bamasuntswana okanye awufuni kutshintsha, ke ngoko, isantya esihambelanayo seeblades yinto enempembelelo, ebonakaliswa njengesantya esijikelezayo serotor (ekubeni i-stator imile). Ukuba isantya siphezulu, ukuxinana kokusikwa okanye ukubamba i-radial flow fluid iya kuba phezulu, ngoko ke isiphumo sokuhlanjululwa siya kuba namandla, kwaye ngokuphendululekileyo. Nangona kunjalo, ukuphakama kwesantya somgca, kungcono. Xa ifikelela kwixabiso eliphezulu kakhulu, kukho ukuthambekela kokuyeka ukuhamba, ngoko ke ukuhamba kuba kuncinci kakhulu, ukushisa kuphezulu kakhulu, kwaye ezinye izinto ziqokelela, ezikhokelela kwiziphumo ezingaphantsi.
