Injini cylinder liner uye piston mhete iviri yefriction pairi inoshanda pasi pekushisa kwepamusoro, kudzvanywa, kuchinjika mutoro uye ngura. Kushanda mumamiriro ezvinhu akaoma uye anoshanduka kwenguva yakareba, chigumisiro ndechokuti cylinder liner yakasakara uye yakasvibiswa, iyo inokanganisa simba, hupfumi uye hupenyu hwebasa rejini. Izvo zvakakosha kuti uongorore zvikonzero zvekupfeka silinda liner uye deformation yekuvandudza hupfumi hweinjini.
1. Chikonzero chekuongorora chekupfeka kwe cylinder liner
Nzvimbo yekushanda ye cylinder liner yakaipa kwazvo, uye kune zvikonzero zvakawanda zvekupfeka. Kupfeka kwakajairwa kunowanzo bvumidzwa nekuda kwezvikonzero zvechimiro, asi kushandiswa zvisina kunaka uye kugadzirisa zvinokonzeresa kupfeka.
1 Kupfeka kunokonzerwa nezvikonzero zvemaitiro
1) Mamiriro ekuzora haana kunaka, kuitira kuti chikamu chepamusoro che cylinder liner chipfeke zvakanyanya. Chikamu chepamusoro checylinder liner chiri padyo nekamuri yekupisa, tembiricha yakakwira zvakanyanya, uye mamiriro ekuzora akashata. Kukukurwa uye kunyungudutswa kwemweya mutsva uye mafuta asina kufukidzwa anowedzera kuderera kwemamiriro ekumusoro, zvekuti humburumbira iri munzvimbo yakaoma friction kana semi-dry friction, icho chinokonzera kusakara kwakakomba pahumburumbira yepamusoro.
2) Chikamu chepamusoro chiri pasi pekumanikidzwa kukuru, kuitira kuti cylinder ipfeke inorema kumusoro uye chiedza pazasi. Iyo piston mhete inotsikirirwa zvakasimba pamadziro ecylinder pasi pekuita kweiyo elasticity uye kumashure kumanikidza. Iyo yakakura kudzvanywa kwakanaka, kunowedzera kuoma kuumbwa uye kuchengetedza kwemafuta ekuzora firimu, uye zvakanyanya kushata kupfeka kwemagetsi. Mubasa rekushanda, sezvo piston inodzika pasi, kudzvinyirira kwakanaka kunoderera zvishoma nezvishoma, saka cylinder kupfeka inorema kumusoro uye chiedza pasi.
3) Mineral acids uye organic acids inoita kuti humburumbira pamusoro iore uye iparare. Mushure mekupiswa kwemusanganiswa unopisa mucylinder, mvura mhute uye acid oxides inogadzirwa, iyo inonyungudika mumvura kuti ibudise mineral acids, pamwe neiyo organic acids inogadzirwa mukupisa, iyo ine corrosive mhedzisiro pamusoro pehumburumbira, uye zvinhu zvinoora zvinokweshwa zvishoma nezvishoma kubva papiston mhete mukukwesha, zvichiita kuti humburumbira liner deformation.
4) Pinda tsvina yemagetsi, kuitira kuti pakati pe cylinder ipfeke. Hupfu mumhepo, kusvibiswa mumafuta ekuzora, nezvimwewo, pinda mupiston uye cylinder madziro zvichikonzera abrasive kupfeka. Kana guruva kana tsvina zvichidzokororwa muhumburumbira nepiston, kumhanya kwekufambisa ndiko kukuru pakati pehumburumbira, iyo inowedzera kupfeka pakati pehumburumbira.
2 Kupfeka kunokonzerwa nekushandisa zvisina kunaka
1) Iyo sefa mhedzisiro yekuzora mafuta sefa haina kunaka. Kana iyo sefa yemafuta yekuzora isiri kushanda nemazvo, mafuta ekuzora haagone kusefa zvinobudirira, uye mafuta ekuzora ane nhamba yakakura yezvimedu zvakaoma anowedzera kupfekedzwa kwemukati memadziro ecylinder liner.
2) Yakaderera kusefa kunyatsoita kwemhepo sefa. Basa refirita yemhepo kubvisa guruva uye jecha zvimedu zviri mumhepo kupinda muhumburumbira kuti uderedze kupfekwa kwecylinder, piston uye piston ring parts. Kuedza kunoratidza kuti kana injini isina kugadzirwa nemhepo sefa, kupfeka kwecylinder kuchawedzera ne6-8 nguva. Iyo sefa yemhepo haina kucheneswa uye kuchengetwa kwenguva yakareba, uye iyo filtration mhedzisiro haina kunaka, iyo inomhanyisa kupfeka kwecylinder liner.
3) Kushanda kwenguva refu kwekushisa kwakadzika. Kumhanya panguva yakaderera tembiricha kwenguva yakareba, imwe ndeyekukonzera kupisa kwakashata, kuunganidza kabhoni kunotanga kupararira kubva kumusoro kweiyo cylinder liner, zvichiita kuti zvakakomba abrasive kupfeka pachikamu chepamusoro checylinder liner; Chechipiri ndechekukonzera kuparara kwe electrochemical.
4) Kazhinji shandisa yakaderera mafuta ekuzora. Vamwe varidzi kuitira kuchengetedza mari, kazhinji muzvitoro zvemigwagwa kana vatengesi vemafuta zvisiri pamutemo kuti vatenge yakaderera mafuta ekuzora kuti vashandise, zvichikonzera kukora kwakasimba kwepamusoro cylinder liner, kupfeka kwayo kwakakura kakapetwa ka1-2 pane yakajairika kukosha.
3 Kupfeka kunokonzerwa nekuchengetedza kusina kunaka
1) Yakashata cylinder liner yekuisa chinzvimbo. Pakuisa cylinder liner, kana paine chikanganiso chekuisa, iyo silinda yepakati mutsara uye crankshaft axis haina kumira mushe, zvinokonzeresa kusapfeka kwecylinder liner.
2) Kubatanidza tsvimbo yemhangura gomba kutsauka. Mukugadzirisa, kana tsvimbo yekubatanidza musoro wemhangura yakasungirirwa, iyo remer tilt inoita kuti tsvimbo yekubatanidza yemhangura yegomba ive yakatsveyamiswa, uye mutsara wepakati wepiston haufananidzi nepakati mutsara wetambo yekubatanidza musoro mudiki. , kumanikidza piston kuti irereke kune rumwe rutivi rwe cylinder liner, izvo zvichakonzerawo kupfekedzwa kusina kujairika kwe cylinder liner.
3) Kubatanidza tsvimbo yekubhenda deformation. Nekuda kwetsaona dzemotokari kana zvimwe zvikonzero, tsvimbo yekubatanidza ichakotama nekuremara, uye kana ikasaruramiswa nenguva uye ichiramba ichishandiswa, ichawedzerawo kupfeka kwecylinder liner.
2. Matanho ekuderedza cylinder liner kupfeka
1. Tanga uye tanga nemazvo
Kana injini inotanga kutonhora, nekuda kwekushisa kwakadzika, viscosity huru yemafuta uye kusanaya kwemvura, pombi yemafuta haina kukwana. Panguva imwecheteyo, mafuta ari pamudhuri wecylinder yepakutanga anoyerera achidzika pamadziro ecylinder mushure mekumira, saka mafuta haana kunaka seaya mukushanda kwakajairika panguva yekutanga, zvichikonzera kuwedzera kukuru kwekupfeka kwecylinder wall. panotanga. Nokudaro, kana uchitanga kekutanga, injini inofanira kuvharwa kwechinguva chiduku, uye nzvimbo yekukwenya inofanira kuzorwa isati yatanga. Mushure mekutanga, kushanda kusina basa kunofanira kupiswa, kunorambidzwa zvachose kuputika chiteshi chemafuta, uye wozotanga kana tembiricha yemafuta yasvika 40 ℃; Kutanga kunofanirwa kunamatira kune yakaderera-kumhanya giya, uye nhanho nhanho giya rega rega kutyaira chinhambwe, kudzamara tembiricha yemafuta yakajairika, inogona kutendeukira kune yakajairwa kutyaira.
2. Kusarudzwa kwakarurama kwemafuta ekuzora
Kunyatsoenderana nemwaka uye injini kuita zvinodiwa kusarudza yakanakisa viscosity kukosha kwemafuta ekuzora, haigone kutengwa pamadiro neakaderera mafuta ekuzora, uye kazhinji tarisa uye chengetedza huwandu uye kunaka kwemafuta ekuzora.
3. Simbisa kuchengetedza kwesefa
Kuchengeta sefa yemhepo, sefa yemafuta uye sefa yemafuta munzvimbo yakanaka yekushanda kwakakosha kudzikisa kupfeka kwecylinder liner. Kusimbisa kuchengetedza kwe "mafirita matatu" chiyero chakakosha chekudzivirira kusvibiswa kwemichina kupinda muhumburumbira, kuderedza kupfeka kwecylinder, uye kuwedzera hupenyu hwebasa rejini, iyo inonyanya kukosha kumaruwa uye nzvimbo dzine jecha. Zvakaipa chose kuti vamwe vatyairi havaisi mafirita emhepo kuitira kuchengetedza mafuta.
4. Chengetedza injini pane yakajairika tembiricha yekushanda
Iyo yakajairika tembiricha yeinjini inofanira kunge iri 80-90 ° C. Iyo tembiricha yakadzikira uye haigone kuchengetedza mafuta akanaka, izvo zvinowedzera kupfekwa kwemadziro ecylinder, uye mhute yemvura muhumburumbira iri nyore kunyura mumvura. madonhwe, nyungudutsa mamorekuru egasi ane acidic mugasi rekuburitsa, gadzira zvinhu zvine acidic, uye gadzira madziro ecylinder pasi pekuora uye kupera. Muedzo unoratidza kuti kana tembiricha yemadziro cylinder yadzikiswa kubva pa90 ℃ kusvika pa50 ℃, kupfeka silinda kunopetwa 4 pane zve90 ℃. Tembiricha yakakwira zvakanyanya, inoderedza simba rehumburumbira uye kuwedzera kupfeka, uye inogona kutokonzera kuti piston iwedzere uye kukonzera "cylinder kuwedzera" tsaona.
5. Kuvandudza waranti yemhando
Mukushandiswa kwekushandiswa, matambudziko anowanikwa munguva yekubviswa nenguva, uye zvikamu zvakakuvadzwa uye zvakaremara zvinotsiviwa kana kugadziriswa chero nguva. Paunenge uchiisa cylinder liner, tarisa uye uunganidze zvakanyatsoenderana nehunyanzvi zvinodiwa. Muchigadziro chekugadzirisa mhete yewaranti, mhete yepiston ine elasticity yakakodzera inofanira kusarudzwa, iyo elasticity yakanyanya kuduku, kuitira kuti gasi rinoputika mukati me crankcase uye rinoputira mafuta pamadziro evhavha, kuwedzera cylinder wall kupfeka; Yakawandisa elastic simba inokonzeresa kupfekedzwa kwecylinder madziro, kana kupfeka kunowedzera nekuparadzwa kwefirimu remafuta pamadziro ecylinder.
Crankshaft yekubatanidza rod jenari uye main shaft jenari haina kufanana. Nekuda kwekupisa mataira uye zvimwe zvikonzero, crankshaft ichakanganiswa nekukanganisa kwakanyanya, uye kana ikasagadziriswa nekufamba kwenguva uye ichiramba ichishandiswa, inomhanyisa kupfeka silinda liner.
