Sefa yamafuta, yomwe imadziwikanso kuti grid yamafuta.Amagwiritsidwa ntchito pochotsa zonyansa monga fumbi, tinthu tachitsulo, ma depositi a kaboni ndi timadontho ta mwaye mumafuta a injini kuteteza injini.
Fyuluta yamafuta imagawidwa mumtundu wathunthu komanso mtundu wogawanika.Fyuluta yothamanga kwambiri imalumikizidwa mndandanda pakati pa mpope wamafuta ndi njira yayikulu yamafuta, kotero imatha kusefa mafuta onse opaka omwe amalowa munjira yayikulu yamafuta.Chotsukira chogawanitsa chimalumikizidwa molumikizana ndi njira yayikulu yamafuta kuti isefa gawo lokha la mafuta opaka mafuta omwe amatumizidwa ndi mpope wamafuta.
Mawu Oyamba
Pa ntchito ya injini, zitsulo kuvala zinyalala, fumbi, madipoziti mpweya ndi madipoziti colloidal oxidized pa kutentha, madzi, etc. mosalekeza wothira mafuta mafuta.Ntchito ya fyuluta yamafuta ndikusefa zonyansa zamakina ndi mkamwa, kusunga mafuta opaka mafuta kukhala oyera, ndikuwonjezera moyo wake wantchito.Sefa yamafuta iyenera kukhala ndi mphamvu zosefera mwamphamvu, kukana kuyenda kochepa, komanso moyo wautali wautumiki.Nthawi zambiri, zosefera zingapo zokhala ndi zosefera zosiyanasiyana zimayikidwa mu zosefera zosefera, zosefera zowoneka bwino ndi zosefera zabwino, zomwe zimalumikizidwa motsatana kapena mndandanda munjira yayikulu yamafuta.(Cholumikizidwa mu mndandanda ndi gawo lalikulu la mafuta chimatchedwa fyuluta yothamanga kwambiri. Pamene injini ikugwira ntchito, mafuta onse opaka mafuta amasefedwa kupyolera mu fyuluta; yomwe imagwirizanitsidwa mofanana imatchedwa sefa yogawanitsa).Pakati pawo, coarse fyuluta imodzi imalumikizidwa mndandanda mu gawo lalikulu lamafuta, lomwe ndi mtundu wathunthu wotuluka;fyuluta yabwino imalumikizidwa mofanana mumsewu waukulu wamafuta, womwe ndi mtundu wogawanika.Injini zamagalimoto zamakono nthawi zambiri zimakhala ndi zosefera komanso zosefera mafuta.Zosefera zowoneka bwino zimasefa zonyansa zokhala ndi tinthu tating'ono 0.05mm kapena kupitilira apo mumafuta, ndipo fyuluta yabwino imagwiritsidwa ntchito kusefa zonyansa zokhala ndi tinthu tating'ono 0.001mm kapena kupitilira apo.
Makhalidwe aukadaulo
●Pepala losefera: Zosefera zamafuta zimakhala ndi zofunika kwambiri pamapepala osefera kuposa zosefera mpweya, makamaka chifukwa kutentha kwamafuta kumasiyanasiyana kuchokera ku 0 mpaka 300 madigiri.Pansi pa kusintha kwakukulu kwa kutentha, kuchuluka kwa mafuta kudzasinthanso moyenera.Zidzakhudza kusefa kwa mafuta.Pepala losefera la sefa yamafuta apamwamba liyenera kusefa zonyansa pansi pakusintha kwakukulu kwa kutentha ndikuwonetsetsa kuyenda kokwanira.
●Mphete yosindikizira: Mphete yosindikiza yamafuta apamwamba kwambiri imapangidwa ndi mphira wapadera kuti iwonetsetse kuti 100% yatuluka mafuta.
●Valve yopondereza kumbuyo: imapezeka muzosefera zamafuta apamwamba kwambiri.Injini ikazimitsidwa, imatha kuletsa fyuluta yamafuta kuti isaume;injini ikayatsidwanso, nthawi yomweyo imatulutsa mphamvu kuti ipereke mafuta kuti azipaka injini.(Amatchedwanso check valve)
●Vavu yothandizira: imapezeka muzosefera zamafuta apamwamba kwambiri.Pamene kutentha kwakunja kumatsikira ku mtengo wina kapena pamene fyuluta ya mafuta ikupitirira moyo wautumiki wamba, valavu yowonongeka idzatsegulidwa pansi pa kupanikizika kwapadera, kulola mafuta osasefedwa kuti ayende molunjika mu injini.Komabe, zonyansa zamafuta zidzalowa mu injini limodzi, koma kuwonongeka kwake kumakhala kochepa kwambiri kuposa kuwonongeka komwe kumabwera chifukwa cha kusowa kwa mafuta mu injini.Chifukwa chake, valavu yakusefukira ndiye chinsinsi choteteza injini pakagwa mwadzidzidzi.(Amatchedwanso bypass valve)
Kusintha kozungulira
●Kuyika:
a) Kukhetsa kapena kuyamwa mafuta a injini akale
b) Masulani zomangira ndikuchotsa fyuluta yakale yamafuta
c) Ikani mafuta osanjikiza pa mphete yosindikizira ya fyuluta yatsopano yamafuta
d) Ikani fyuluta yatsopano yamafuta ndikumangitsa zomangira
●Kuzungulira komwe kumalimbikitsidwa: magalimoto ndi magalimoto ogulitsa amasinthidwa kamodzi miyezi isanu ndi umodzi iliyonse
Zofunikira zamagalimoto zosefera mafuta
Zosefera mwatsatanetsatane, zosefera zonse particles> 30 um,
Chepetsani tinthu tating'onoting'ono tomwe timalowa mpata wothira mafuta ndikupangitsa kuvala (<3 um-30 um)
Kuthamanga kwa mafuta kumayenderana ndi kufunikira kwa mafuta a injini.
Nthawi yayitali yosinthira, yotalikirapo kuposa moyo wamafuta (km, nthawi)
Kulondola kwa kusefa kumakwaniritsa zofunikira zoteteza injini ndikuchepetsa kuvala.
Kuchuluka kwa phulusa lalikulu, koyenera kumadera ovuta.
Imatha kuzolowera kutentha kwamafuta ambiri komanso malo owononga.
Mukasefa mafuta, kutsitsa kutsika kwapakati, kuli bwino, kuonetsetsa kuti mafuta amatha kudutsa bwino.
Ntchito
Nthawi zonse, mbali zonse za injini ndi afewetsedwa ndi mafuta kukwaniritsa ntchito bwinobwino, koma tchipisi zitsulo, fumbi, madipoziti mpweya kuti oxidized pa kutentha kwambiri ndi nthunzi ena madzi adzakhala mosalekeza kusanganikirana pamene mbali ikuyenda.Mu mafuta a injini, moyo wautumiki wa mafuta a injini udzachepetsedwa pakapita nthawi, ndipo kugwira ntchito kwa injini kungakhudzidwe kwambiri.
Choncho, udindo wa mafuta fyuluta zikuonekera pa nthawi ino.Mwachidule, ntchito yayikulu ya fyuluta yamafuta ndikusefa zonyansa zambiri mumafuta, kusunga mafuta oyimilira kukhala oyera, ndikuwonjezera moyo wake wanthawi zonse.Kuphatikiza apo, fyuluta yamafuta iyeneranso kukhala ndi mphamvu zosefera zolimba, kukana kutsika kochepa, komanso moyo wautali wautumiki.
