Sefa yemafuta.
Oiri sefa, inozivikanwawo segridi yemafuta. Inoshandiswa kubvisa tsvina yakaita seguruva, simbi zvidimbu, carbon precipitates uye soot particles mumafuta kudzivirira injini.
Oiri sefa ine kuyerera kuzere uye shunt mhando. Iyo yakazara-yekuyerera sefa yakabatanidzwa munhevedzano pakati pepombi yemafuta uye nzira huru yemafuta, saka inogona kusefa mafuta ese ekuzora achipinda mugedhi remafuta. Iyo shunt yekuchenesa iri mukufambirana neiyo huru nzira yemafuta, uye chikamu chete chemafuta ekuzora anotumirwa nepombi yemafuta esefa inosefa.
Munguva yekushanda kweinjini, zvimedu zvesimbi, guruva, kabhoni inoiswa oxidized pakupisa kwakanyanya, colloidal sediments, uye mvura zvinogara zvichisanganiswa nemafuta ekuzora. Basa resefa yemafuta nderokusefa kunze uku kusvibiswa kwemuchina uye glia, kuchengetedza mafuta ekuzora akachena, uye kuwedzera hupenyu hwayo hwesevhisi. Iyo sefa yemafuta inofanirwa kunge iine simba rekusefa, diki yekuyerera kuramba, hupenyu hurefu hwesevhisi uye zvimwe zvivakwa. Iyo general lubrication system inoshongedzerwa akati wandei mafirita ane akasiyana kusefa huwandu - iyo yekuunganidzira sefa, iyo coarse sefa uye yakanaka sefa, zvichiteerana kana nhevedzano munzira huru yemafuta. (Iyo yakazara-inoyerera sefa yakatevedzana ine huru yemafuta ndima inonzi, uye mafuta ekuzora anosefa nesefa kana injini iri kushanda; Parallel nayo inonzi shunt filter). Iyo coarse sefa yakabatanidzwa munhevedzano muchikamu chikuru chemafuta ekuyerera kwakazara; Iyo yakanaka sefa inotenderedzwa mukufambirana mugero guru remafuta. Injini dzemotokari dzemazuva ano dzinowanzova nesefa yekuunganidzira uye sefa yemafuta inoyerera. Iyo coarse sefa inobvisa tsvina muoiri ine chidimbu saizi inodarika 0.05mm, uye iyo yakanaka sefa inoshandiswa kusefa kunze tsvina yakanaka nehukuru hunopfuura 0.001mm.
Unyanzvi hunoita
● Pepa refirita: Iyo sefa yemafuta ine zvinodiwa zvepamusoro zvesefa pepa pane mhepo sefa, kunyanya nekuti tembiricha yemafuta inosiyana kubva pa0 kusvika ku300 madhigirii, uye kuwanda kwemafuta kunochinjawo zvinoenderana pasi pekushanduka kwekushisa kwakanyanya, izvo zvinokanganisa. kusefa kuyerera kwemafuta. Iyo sefa bepa remhando yepamusoro-soro sefa yemafuta inofanirwa kukwanisa kusefa kusvibiswa pasi pekuchinja kwakanyanya kwekushisa uku uchiona kuyerera kwakakwana.
● Rubber seal ring: Iyo sefa seal ring yemhando yepamusoro yemafuta inogadzirwa nerabha yakakosha kuti ive nechokwadi chekuti 100% hapana kubuda kwemafuta.
● Return suppression valve: Mafirita emafuta emhando yepamusoro chete aripo. Kana injini yakadzimwa, inogona kudzivirira sefa yemafuta kubva pakuoma; Injini painodzoserwa, inokurumidza kugadzira kudzvanywa uye inopa mafuta ekuzora injini. (inozivikanwawo sevhavha yekudzoka)
● Vhuru yekuyamura: Masefa emafuta emhando yepamusoro chete aripo. Kana tembiricha yekunze ichidonha kune imwe kukosha kana iyo sefa yemafuta inodarika iyo yakajairika yehupenyu hwesevhisi muganhu, vharafu yekuyamura inovhura pasi pekumanikidzwa kwakakosha, ichibvumira mafuta asina kusefa kuti ayerere akananga muinjini. Kunyange zvakadaro, tsvina iri muoiri ichapinda pamwe chete muinjini, asi kukuvara kwacho kuduku kudarika kukuvadzwa kunokonzerwa nokusavapo kweoiri muinjini. Naizvozvo, vharafu yekuyamura ndiyo kiyi yekudzivirira injini munjodzi. (inonziwo bypass valve).
Kangani iyo sefa yemafuta inofanira kuchinjwa
Kudzoreredzwa kwesefa yemafuta kunonyanya kuenderana nerudzi rwemafuta anoshandiswa mumotokari, kusanganisira mineral oil, semi-synthetic mafuta uye yakazara synthetic oiri, uye imwe neimwe mhando yeoiri ine akasiyana ekutsiva. Aya anotevera ndiwo akadzama ekutsiva uye kurudziro:
Mineral oiri: Zvinowanzokurudzirwa kutsiva mafuta sefa ega ega 3000-4000 makiromita kana hafu yegore.
Semi-synthetic mafuta: Iyo yekutsiva inotenderera inowanzo 5000-6000 makiromita kana hafu yegore kutsiva iyo mafuta sefa.
Mafuta ekugadzira akazara: Kutenderera kutenderera kwakareba, kazhinji mwedzi misere yega yega kana 8000-10000 km kutsiva mafuta sefa.
Pamusoro pekutyaira mileage, unogona zvakare kushandura mafuta sefa zvinoenderana nenguva, sezvinotevera:
Mineral mafuta: Shandura yega 5000 km.
Semi-synthetic mafuta: shanduko yega yega 7500 km.
Mafuta ekugadzira akazara: Shandura yega 10,000 km.
Izvo zvinofanirwa kucherechedzwa kuti pese painoshandurwa oiri, iyo sefa yemafuta inofanira kutsiviwa panguva imwe chete kuti ive nechokwadi chekuti injini inogara ichiwana yakachena yemafuta ekuzora. Kana iyo sefa yemafuta ikasatsiviwa nenguva, inogona kutungamira mukuvharika kwesefa, zvichikanganisa kuyerera kwemafuta, uye zvino kukanganisa kushanda uye hupenyu hweinjini. ,
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
