Oiri sefa, inozivikanwawo segridi yemafuta.Inoshandiswa kubvisa tsvina yakaita seguruva, zvimedu zvesimbi, carbon deposits uye soot particles mumafuta ejini kudzivirira injini.
Iyo mafuta sefa yakakamurwa kuita yakazara-kuyerera mhando uye kupatsanurwa-kuyerera mhando.Iyo yakazara-inoyerera sefa yakabatanidzwa munhevedzano pakati pepombi yeoiri uye nzira huru yemafuta, saka inogona kusefa mafuta ese ekuzora anopinda mugero remafuta.Iyo yekuparadzanisa-kuyerera yekuchenesa inobatanidzwa mukufambirana neiyo huru nzira yemafuta kusefa chete chikamu chemafuta ekuzora anotumirwa nepombi yemafuta.
Nhanganyaya
Munguva yekushanda kweinjini, simbi inopfeka marara, guruva, kabhoni deposits uye colloidal deposits oxidized pakupisa kwakanyanya, mvura, nezvimwe zvinogara zvichisanganiswa mumafuta ekuzora.Basa resefa yemafuta nderokusefa kunze kusvibiswa kwemuchina uye mazamu, kuchengetedza mafuta ekuzora akachena, uye kuwedzera hupenyu hwayo hwesevhisi.Iyo sefa yemafuta inofanirwa kunge iine simba rekusefa, yakaderera kuyerera, uye hupenyu hurefu hwesevhisi.Kazhinji, mafirita akati wandei ane hunyanzvi hwekusefa anoiswa mune lubrication system-filter muunganidzi, coarse sefa uye yakanaka sefa, ayo akabatana akabatana kana munhevedzano muchikamu chikuru chemafuta.(Iyo yakabatanidzwa munhevedzano ine mugero mukuru weoiri inonzi full-flow sefa. Kana injini iri kushanda, mafuta ose ekuzora anosefa nesefa; iyo yakabatana neparallel inonzi split-flow sefa).Pakati pavo, iyo coarse sefa imwe yakabatanidzwa munhevedzano muchikamu chikuru chemafuta, iyo izere kuyerera mhando;iyo yakanaka sefa yakabatanidzwa mukuenderana mune huru yemafuta mugero, inova inopatsanurwa kuyerera mhando.Injini dzemotokari dzemazuva ano kazhinji dzine sefa uye sefa yemafuta inoyerera.Iyo coarse sefa inosefa tsvina ine chidimbu saizi ye 0.05mm kana kupfuura mumafuta, uye iyo yakanaka sefa inoshandiswa kusefa kunze tsvina yakanaka ine chidimbu saizi ye0.001mm kana kupfuura.
Unyanzvi hunoita
●Pepa resefa: Mafirita emafuta ane zvakakwirira zvinodiwa papepa resefa pane mafirita emhepo, zvakanyanya nekuti tembiricha yemafuta inosiyana kubva pa0 kusvika pa300 madhigirii.Pasi pekuchinja kwakanyanya kwekushisa, huwandu hwemafuta hunochinjawo maererano.Ichakanganisa kusefa kwemafuta.Iyo sefa bepa remhando yepamusoro-soro sefa yemafuta inofanirwa kukwanisa kusefa tsvina pasi pekuchinja kwakanyanya kwekushisa uku uchiona kuyerera kwakakwana.
●Rubha yekuisa chisimbiso mhete: Iyo sefa yekuisa chisimbiso mhete yemhando yepamusoro injini yemafuta inogadzirwa nerabha yakakosha kuve nechokwadi chekudonha kwemafuta zana.
●Backflow kudzvinyirira vharafu: inongowanikwa mumhando yepamusoro mafirita emafuta.Kana injini yakadzimwa, inogona kudzivirira sefa yemafuta kubva pakuoma;injini painobatidzwazve, inobva yaita kudzvanywa kwekupa mafuta ekuzora injini.(Inonziwo cheki valve)
●Varuvhu yekuyamura: inongowanikwa mumhando yepamusoro mafirita emafuta.Kana tembiricha yekunze ichidonha kune imwe kukosha kana iyo sefa yemafuta inodarika hupenyu hwesevhisi yakajairwa, vharafu yekufashukira inovhura pasi pekumanikidzwa kwakakosha, ichibvumira mafuta asina kusefa kuti ayerere akananga muinjini.Zvakadaro, kusachena kuri muoiri kuchapinda pamwe chete muinjini, asi kukuvara kudiki pane kukuvadzwa kunokonzerwa nekusavapo kweoiri muinjini.Naizvozvo, vharafu yekufashukira ndiyo kiyi yekudzivirira injini munjodzi.(Inozivikanwawo sekuti bypass valve)
Replacement cycle
●Kuiswa:
a) Bvisa kana kusveta mafuta einjini yekare
b) Sunungura zvigadziriso zvekugadzirisa uye bvisa mafuta ekare
c) Isa chidimbu chemafuta parin'i yekuvharisa yesefa itsva yemafuta
d) Isa iyo itsva mafuta sefa uye simbisa zvigadziriso zvekugadzirisa
●Inokurudzirwa kutsiva kutenderera: mota nemotokari dzekutengesa dzinotsiviwa kamwe chete mwedzi mitanhatu yega yega
Zvemotokari zvinodiwa zvemafuta mafirita
Sefa chaiko, sefa zvese zvimedu> 30 um,
Deredza zvimedu zvinopinda mugedhi rekuzora uye kukonzera kupfeka (<3 um-30 um)
Kuyerera kwemafuta kunoenderana nezvinodiwa neoiri injini.
Yakareba kutsiva kutenderera, inokwana kureba kupfuura hupenyu hwemafuta (km, nguva)
Iko kusefa kunoenderana nezvinodiwa zvekudzivirira injini uye kuderedza kupfeka.
Huru hwemadota, inokodzera nharaunda dzakaoma.
Inogona kuchinjika kune yakakwira tembiricha yemafuta uye nharaunda inoora.
Paunenge uchisefa oiri, iyo inodzika iyo yekumanikidza musiyano, zviri nani, kuve nechokwadi chekuti mafuta anogona kupfuura zvakanaka.
Function
Mumamiriro ezvinhu akajairwa, zvikamu zvese zveinjini zvinozorwa neoiri kuti zvikwanise kushanda zvakajairwa, asi simbi machipisi, guruva, kabhoni deposits inoiswa oxidized pakupisa kwakanyanya uye imwe mhute yemvura inoramba ichisanganiswa mukati kana zvikamu zviri kushanda.Mumafuta einjini, hupenyu hwesevhisi yeoiri yeinjini huchaderedzwa nekufamba kwenguva, uye kushanda kwakajairika kweinjini kunogona kukanganiswa mumatambudziko akaomarara.
Naizvozvo, basa remafuta sefa rinoratidzwa panguva ino.Zvichitaurwa zviri nyore, basa guru resefa yemafuta nderokusefa yakawanda yetsvina muoiri, kuchengeta mafuta ekumira akachena, uye kuwedzera hupenyu hwayo hwesevhisi.Pamusoro pezvo, iyo sefa yemafuta inofanirwawo kuve nekuita kwesimba rekusefa kwakasimba, kushomeka kwekuyerera, uye hupenyu hurefu hwesevhisi.
