Kutulutsa nkhungu yamafuta panthawi yogwira ntchito kwakhala mutu wovuta kwa ogwiritsa ntchito mapampu otsekera otsekedwa ndi mafuta. Pameneolekanitsa nkhungu mafutaadapangidwa kuti athetse nkhaniyi moyenera, ogwiritsa ntchito ambiri akupitilizabe kuwona nkhungu yamafuta padoko lotayirira la olekanitsa pambuyo pa kukhazikitsa. Ogwiritsa ntchito ambiri mwachibadwa amakayikira kuti zinthu zosefera sizili bwino ndiye zayambitsa, poganiza kuti kusefera kwamafuta sikukwanira.
Zowonadi, zosefera zocheperako zolekanitsa mafuta zokhala ndi mafuta ochepa olekanitsa gasi zitha kulephera kusefa kwathunthu nkhungu yamafuta yomwe imatulutsidwa ndi mapampu a vacuum, zomwe zimapangitsa kuti chifunga chiwonekerenso padoko lotayirira. Komabe, kubwereza kwa nkhungu yamafuta sikumawonetsa zosefera zolakwika nthawi zonse. Apa ndipamene ambiri ogwiritsa ntchito pampu ya vacuum amalakwitsa - kulumikiza mzere wobwerera wamafuta molakwika.
M'malo mwake, takumana ndi zochitika zingapo pomwe kukhazikitsa kolakwika kudayambitsawolekanitsawonongeka. Monga momwe zasonyezedwera pachithunzi pamwambapa, ogwiritsa ntchito ena amalumikiza molakwika chingwe chobwezera mafuta ku doko lolowera la olekanitsa. Paipiyi idapangidwa kuti ibwezere madontho amafuta omwe agwidwa ku nkhokwe yamafuta yapampu kapena chidebe chakunja. Komabe, ikayikidwa molakwika, mosadziwa imakhala njira ina yotulutsa mpweya wopopera.
Mfundo yofunika kwambiri ikugwira ntchito apa:zoseferakumapangitsa kuti mpweya usavutike. Poganizira kusankha pakati pa kudutsa fyuluta yoletsa kapena kutenga njira yopanda malire, mtsinje wa gasi udzakomera njira yosakanizidwa pang'ono. Chifukwa chake, mpweya wochuluka wosasefedwa umalambalala chinthu chonsecho. Yankho lake ndi lolunjika - ingolumikizaninso chingwe chobwezera mafuta ku doko lotengera mafuta la vacuum pump, mosungiramo mafuta, kapena chidebe choyenera chakunja.
Cholakwika choyika ichi chikufotokozera chifukwa chake zina zikugwira ntchito bwinoolekanitsa nkhungu mafutakuwoneka osagwira ntchito. Kukonza kasinthidwe ka mzere wobwerera wamafuta kumathetsa vuto nthawi yomweyo, kulola olekanitsa kuti azichita momwe amafunira. Zina zomwe zingatheke koma zomwe sizidziwika bwino ndi monga kuchuluka kwa mafuta pampopu, kusanja kolakwika kwa olekanitsa pakugwiritsa ntchito, kapena kutentha kwambiri komwe kumakhudza kukhuthala kwamafuta. Komabe, kutsimikizira kukhazikitsa kuyenera kukhala njira yoyamba yothetsera mavuto musanaganizire zinthu zina izi.
