Zinthu zosefera pampu yamafuta zokhala ndi zonyezimira, zowoneka bwino zimatha kuwoneka zokopa, koma nthawi zambiri zimatha kuyambitsa zovuta zomwe sizingachitike. Makasitomala ambiri anena za vuto lodziwika bwino: atagula zomwe zimawoneka ngati "zotsika mtengo"fyuluta yamafuta, mapampu awo a vacuum anayamba kukumana ndi vuto lotayirira bwino, kuwonjezereka kwa mafuta, ndi kusintha kwafupipafupi kwa mafuta. Chifukwa chiyani izi zimachitika?
Malinga ndi ndemanga yamakasitomala, kuipitsidwa kwakukulu kwamafuta a pampu kumachitika nthawi zonse pambuyo posinthafyuluta yamafuta amafuta,ngakhale machitidwe awo osefera amalowetsedwa anali osamalidwa bwino. Izi zikuwonetsa kuti fyuluta yamafuta ndiye idayambitsa. Kuchokera pazithunzi zoperekedwa ndi makasitomala, pamwamba pa zosefera zimawoneka zosalala modabwitsa, mwina chifukwa chogwiritsa ntchito thonje lopaka utoto pazokongoletsa. Ngakhale izi zitha kukulitsa chidwi chowoneka, sizikufanana ndi mawonekedwe apamwamba. M'malo mwake, zosefera zamafuta zogwira ntchito kwambiri ziyenera kukhala zowawa pang'ono. Kupopera mankhwala zomatira pamwamba si mbali ya muyezo kupanga ndondomeko.
Ngakhale kupopera mbewu mankhwalawa kungapangitse mawonekedwe a fyuluta, zomatira zimatha kutseka ma pores a zinthu zosefera, kulepheretsa kusefera kwamafuta ndi kutulutsa, zomwe zimapangitsa kuti pampu ya vacuum ikhale yocheperako. Kuonjezera apo, pamene pampu ya vacuum imagwira ntchito pamtunda wokwera, zomatira pa fyuluta zimatha kusungunuka ndi kusakaniza ndi mafuta osungunuka. Mafuta oipitsidwawa kenaka amabwereranso m’nkhokwe ya mafuta, kuwononga dongosolo lonse la mafuta.
Mosiyana, athufyuluta yamafutazinthu sizimapoperapo zomatira pazifukwa zodzikongoletsera. Ngakhale amawoneka ovuta pang'ono, amapereka kukana kochepa komanso kutulutsa mafuta mwachangu, kuwonetsetsa kuti magwiridwe antchito ndi odalirika. Ndi zaka khumi ndi zitatu zazaka zambiri pantchito yosefera pampu ya vacuum, tadzipereka kupereka zinthu zomwe zimathetsa mavuto a makasitomala. Zomwe takumana nazo zatiphunzitsa kuti mawonekedwe owoneka bwino komanso nkhondo zamitengo sizokhazikika-kokha khalidwe lapamwamba limatsimikizira kudalirika kwa nthawi yayitali komanso kukhutira kwamakasitomala.
