Kumizidwa kwamafuta otentha: Zilowerereni mbali zotsukidwa zotsukidwa mumafuta otentha pa 80 ~ 120 ℃ kwa ola limodzi.Pamene mankhwalawo amatenthedwa, mpweya wa pores wolumikizidwa umakula.Mbali ya mpweya imatulutsidwa.Pambuyo pozizira, mpweya wotsalawo umachepanso, kukokera mafuta mu pores.Chifukwa mafuta otentha amakhala ndi madzi abwino komanso mafuta ambiri, mafuta ochulukirapo amatha kumizidwa muzogulitsa.Kuchita bwino kwa njira yomiza mafuta ndikwambiri kuposa kumizidwa kwamafuta wamba.

Kumizidwa kwamafuta: Ikani magiya otsukidwa mu bokosi la vacuum, sindikizani ndikutuluka mpaka -72 mm Hg, kenaka yikani mafuta mu bokosi lotsekera, ndikuwotcha mpaka 80 ℃ kwa mphindi 20 mpaka 30.Popeza mpweya wolumikizana ndi nkhaniyo umatulutsidwa, mafuta amatha kulowa m'nkhaniyi mkati mwa mphindi 10.Njirayi imakhala ndi kumiza kwakukulu kwa mafuta komanso kuthamanga kwambiri.

Kumiza mafuta wamba: Ikani chotsukidwa sintered structural mu mafuta (nthawi zambiri 20 ~ 30 mafuta) zilowerere, ndipo mafuta ali pansi pa zochita za capillary mphamvu ya mankhwala.Kumiza mu pores wa mankhwala.Njirayi imakhala ndi mphamvu yochepa yomiza mafuta komanso nthawi yayitali yomiza mafuta, yomwe imatenga maola angapo.Amagwiritsidwa ntchito pazinthu zomwe zili ndi mafuta ochepa.

Mfundo yogwiritsira ntchito njira yomiza mafuta yazinthu zazitsulo za ufa ndikuti chitsulo chokhala ndi mafuta chokhala ndi chitsulo chimasungunuka ndikumizidwa mu mafuta, ndipo mafuta opangira mafuta a ufa amalowa mu pores.Tsinde likazungulira, kukangana kwamphamvu kumachitika ndi manja kuti apange kutentha;kutentha kwa bere kumakwera, ndipo mafuta amakula akatenthedwa;amatuluka kuchokera m'mabowo kuti apereke mafuta okha pakati pa shaft ndi manja, ndipo filimu yamafuta yopangidwa imagwira ntchito popaka mafuta ndi kuchepetsa kukangana.
