Mafuta ari kubuda pasi pesefa yemafuta

Munguva yekushanda kwemotokari, vatyairi vazhinji vanocherechedza kubuda kwemafuta pasi pesefa yemafuta. Dambudziko iri rinogona kuve rakakosha kune varidzi vemotokari dzekare dzine yakakwira mileage, uye kune nyowani nyowani injini dzinopisa.

Muchiitiko chekutanga, mafuta anoyerera achitenderedza sefa yemafuta, nekuti pombi yemafuta eiyo lubrication system inogona kunge isina kumanikidza kuderedza valve isingabvumiri kudzvinyirira kwakanyanya muhurongwa. Kazhinji, dambudziko rinozviratidza mushure mekutonhora kwekutanga munguva yechando, apo mafuta anokora mukrankcase yemagetsi unit. Iyo girisi haina nguva yekupfuura nemusefa, zvichiita kuti mafuta abudiswe kunze.

Nezvinjini zvemazuva ano, kudonha kwechikonzero ichi kazhinji hakubvumirwi, sezvo kuvapo kwevhavha yekuyamura yakanyanyisa mukugadzirwa kwemaitiro emazuva ano kunobvisa mukana uyu. Nechikonzero ichi, kubuda kweoiri pasi pemafuta sefa imba kusashanda uye inova chikonzero chekuongorora simba remagetsi.

Muchinyorwa chino, isu tichataura nezvekuti sei mafuta ari kubuda kubva musefa yemafuta, zvekuita kana mafuta adonha akawanikwa pasi pechivharo kana mafuta sefa pekugara, uye maitiro ekugadzirisa.

Nei mafuta achiyerera kubva pasi pemafuta sefa

Kutanga, iyo rondedzero yezvikonzero nei mafuta ichidonha kubva munzvimbo yemafuta sefa yakawandisa. Kazhinji kazhinji, ane mhosva ndiye muridzi pachake, uyo asina kuchinja mafuta sefa kwenguva yakareba.

• Kusvibiswa kwesefa yemafuta pasi pemamwe mamiriro kunogona kutungamira kune chokwadi chekuti kuita kwakadzikira zvakanyanya, iyo lubricant haipfuuri nepakati pesefa. Panguva imwecheteyo, kudzivirira kubva kuoiri nzara yeinjini, iyo sefa dhizaini kazhinji ine yakakosha bypass vharafu (inobvumira mafuta kunzvenga iyo sefa element), asi hazvibviri kusabvisa mukana wekutadza panguva yekushanda kwayo.

Muchiitiko chekuti kuchena uye "kutsva" kwesefa hakusi kupokana, zvikanganiso zvinogona kunge zvakaitwa panguva yekuiswa kwayo. Kana kuvuza kukaitika pakarepo mushure mekutsiva sefa, zvinogoneka kuti sefa haina kusimbiswa zvakakwana kana imba haina kumonyoroka (munyaya yedhizaini inodonha). Izvi zvinoratidza kudiwa kwekusimbisa. Iyi nzira inoitwa nemaoko kana neakakosha epurasitiki kiyi yekudonhedza.

Chinhu chinodiwa chinogona kutariswa kusavapo kwesimba pakutendeuka, sezvo kusungirirwa kunotungamira kuputika kwerabha yekuisa chisimbiso uye deformation yemhete yekuisa chisimbiso. Muchiitiko ichi, zvinodikanwa kutsiva sefa neitsva kana kugadzirisa dambudziko nekutsiva chisimbiso chakakanganisika.

Isu tinowedzera kuti kazhinji panguva yekumisikidza, varidzi vemotokari uye makanika vanokanganwa kuzora iyo yekare rubber o-ring pamafuta sefa imba nemafuta einjini. Izvi zvinotungamira kune chokwadi chekuti mushure mekusunungura sefa, inogona kuve yakasununguka, chisimbiso chingave chakaremara kana kuiswa chakakombama.

Chero zvazvingaitika, iyo sefa yemafuta inofanirwa kubviswa, kutendeseka kwechisimbiso kutariswa, bhendi rerubha rakarungwa uye iyo sefa chinhu chinotsiviwa, tichifunga nezvehunhu hwekuiswa kwayo. Inofanirawo kuyeukwa kuti sefa yemafuta isina kunaka inogona kuwanikwa mukutengesa. Mumamiriro ezvinhu akadaro, imba yacho pachayo inogona kunge isina kukanganisa, umo mune kuputika, chisimbiso chinogona kugadzirwa nerabha yakaderera, iyo valve valve haishande, nezvimwewo.

High engine oil pressure ndiyo yechipiri inonyanya kukonzera kudonha kwemafuta kwakatenderedza sefa yemafuta. Kuwedzera kwekudzvinyirirwa muhurongwa hwekuzora kunogona kuitika nekuda kwezvikonzero zvakati wandei, kubva pakukora kwakasimba kwemafuta, pamwe neakawandisa mafuta mazinga, kune kumwe kutadza kwemuchina.

Ngatitangei nevhavha yebypass. Ivhavha yakatsanangurwa inodiwa kuti ibvise kumanikidzwa kwemafuta kana ichidarika kukosha kwakatarwa. Ivhavha inogona kuwanikwa munzvimbo yefiriji inobata, pamwe chete nepombi yemafuta pachayo (zvichienderana nemaitiro ekugadzira). Kuti utarise, unofanirwa kusvika kune valve uye uongorore kushanda kwayo.

Kana ikanamira munzvimbo yakavharwa, iyo element haisi kushanda. Muchiitiko ichi, chigadzirwa chacho chinofanira kucheneswa uye kucheneswa. Nekuchenesa, peturu, carburetor cleaner, parafini, nezvimwewo zvakakodzera. Ndapota cherechedza kuti, sezvinoratidzwa nemaitiro, zviri nani kutsiva mavharuvhu kana zvichibvira, kunyanya kufunga nezvemutengo wayo unodhura.

Chimwe chikonzero chekudonha kwemafuta sefa idambudziko netambo dzefitting panokwizwa sefa. Kana tambo dzakabviswa kana kukuvadzwa, imba yekusefa haigone kusimbiswa panguva yekuiswa, uye oiri inodonha semhedzisiro. Mumamiriro ezvinhu akadaro, zvakakosha kushandura chishongedzo kana kucheka tambo itsva.

Zvakakoshawo kuziva kuti kana mafuta akasarudzwa zvisizvo, kureva kuti, inova yakanyanyisa mvura kana kuti viscous, saka kudonha kunowanzoitika munzvimbo ye gaskets uye zvisimbiso. Sefa yemafuta haina mutsauko. Iyo lubricant inofanira kusarudzwa maererano nezvinodiwa nemugadziri wemotokari, uyewo funga nezvemaitiro uye maitiro ekushanda.

Ndapota cherechedza kuti kana mutyairi achigara achishandisa rudzi rumwe rwemafuta, sefa haina kusvibiswa, pakanga pasina kuchinja kukuru mumamiriro ekunze, uye pasina matambudziko ejini ari pachena, ipapo mafuta ejini ekunyepedzera anogona kunge akazara mujini. Zvinoitika kuti yakaderera-mhando girizi haingove neyakaziviswa zvivakwa, ndosaka kudonha kuchionekwa.

Nzira yekubuda mumamiriro ezvinhu aya iri pachena: zvinofanirwa kutsiva iyo sefa uye mafuta, uye kuwedzera kwekuwedzera kweinjini lubrication system kunogona zvakare kudikanwa. Chekupedzisira, isu tinowedzera kuti kuvharika kwepombi dze crankcase ventilation system kunokonzera kuunganidzwa kwemagasi mukati meinjini yekupisa kwemukati, kuwedzera kwekumanikidza mukati meinjini uye kubuda kwemafuta kuburikidza nemagasi uye zvisimbiso. Iyo yakatsanangurwa crankcase ventilation system inofanirwa kuongororwa panguva yekuongorora, pamwe nekucheneswa nguva nenguva nekuda kwekudzivirira.

Magadzirirwo emafuta sefa yabuda

Saka, kazhinji, zvakakwana kuzadza mafuta emhando yepamusoro, uchifunga nezvekurudziro yemugadziri uye mwaka, kuitira kuti uchinje zvakanaka kana kuisa mafuta sefa.

Nehunyanzvi hwekutanga, zvinokwanisika kubata nekuchenesa crankcase ventilation system. Izvi zvinoreva kuti muzviitiko zvakawanda, anenge mutyairi wese mugaraji anogona kugadzirisa kubuda kwemafuta nemaoko avo.

Kana zviri zvekuputsika kwakaoma, izvi zvinosanganisira kukanganisa kudzikisa vharafu uye tambo dzakakuvadzwa pamafuta sefa inokwirisa inokwana. Mukuita, dambudziko nevhavha rinonyanya kuwanda, saka ngatitarisei pakuiongorora zvakasiyana.

Basa guru nderokutarisa chitubu chevhavha, iyo iri pasi pepuragi. Ndiye iye ane basa rekushanda kwechigadzirwa, kushanda kwese kunoenderana nemamiriro echirimo. Chitubu chakatsanangurwa chinofanira kubviswa kubva paruoko kuti chiongororwe. Kukwenya, makwinya, kupeta uye zvimwe zvirema hazvibvumidzwe. Uyewo, chitubu chinofanira kuva chakasimba, kwete kusununguka.

Kana chitubu chiri nyore kutambanudzwa nemaoko, izvi zvinoratidza kupera simba kwechinhu ichi. Mukuwedzera, kureba kwese kwechitubu hakufaniri kuwedzera, zvichiratidza kutambanudza. Kuderera kwehurefu kunoratidza kuti chikamu chechitubu chakaputsika. Mumamiriro ezvinhu aya, zvinodiwawo kubvisa tsvina kubva pachigaro chevhavha. Kuwana chero kukanganisa muchirimo ndicho chikonzero chekuchitsiva.

Ngationei mhinduro

Sezvauri kuona, kune zvikonzero zvakawanda zvekudonha kwemafuta munzvimbo yemafuta sefa. Izvo zvinodiwa kuti utarise injini mukuita kwechikamu chekuongorora, ndiko kuti, nekubvisa. Mukufambirana nekutsvaga kwedambudziko, unogona kuyera kudzvanywa murubrication system ine mvura yekumanikidza geji, pamwe nekuyera kudzvanywa muinjini.

Kuderera kwekumanikidza mumasilinda kucharatidza kuburitswa kwegasi kubva mukamuri yekupisa uye kuwedzera kwekumanikidza mu crankcase. Fluid pressure gauge kuverenga ichakubatsira kukurumidza kuona kudzvinyirirwa kutsauka mune lubrication system, kana iripo.

Chekupedzisira, isu tinowedzera kuti kana oiri ikayerera ichibva pasi pesefa yemafuta panguva yekutanga-ups kana lubricant ichiyerera nguva dzose, injini ichimhanya uye kudzvanywa murubrication system kwakajairika, uye iyo sefa pachayo yakaiswa nemazvo uye yakachengetedzwa zvakachengeteka. ipapo chikonzero chinogona kunge chiri mumhando yakaderera yesefa pachayo. Muchiitiko ichi, usati wagadzirisa injini inopisa mukati, zviri nani kutanga uchishandura sefa kune chigadzirwa chakapupurirwa kubva kumugadziri anozivikanwa.
