Ukulimala kwangaphambi kwesikhathi kumabheringi ashelelayo kuvame kakhulu kunokuthwala ukutubeka, ngakho-ke kubalulekile ukuvimbela ukulimala kwangaphambi kwesikhathi kumabheringi ashelelayo.Ukugcinwa okulungile kwama-bearings ashibilikayo kuyindlela ephumelelayo yokunciphisa ukulimala kwangaphambi kwesikhathi kuma-bearings kanye nesiqinisekiso esithembekile sokwelula impilo yokuzala.Ngakho-ke, ekunakekeleni kwansuku zonke kanye nokulungiswa kwenjini, ukunakwa kufanele kukhokhwe ekubukeni nasekubunjweni kwe-alloy surface, emuva, ekupheleni kanye namakhona onqenqemeni okuthwala.Izinyathelo zokuthuthukisa izimo zokusebenza ze-bearing, futhi unake ukuvimbela ukulimala kwangaphambi kwesikhathi ku-bearing bearing.

① Kala ngokuqinile ukubumbana nokuba yindilinga kwembobo enkulu yensimbi yomzimba wenjini kadizili.Ukulinganisa ukuhlangana kwembobo eyinhloko yenjini yenjini, ukuhlangana komzimba wenjini ye-diesel okufanele kulinganiswe kunembe kakhudlwana, futhi ukuphuma kwe-crankshaft kukalwa ngasikhathi sinye, ukuze kukhethwe ubukhulu. wesihlahla esithwalayo ukwenza igebe lokugcobisa uwoyela lilingane endaweni ngayinye ye-eksisi.Lapho injini yedizili ike yabhekana namathayela agingqikayo, izimoto ezindizayo, njll., ukubumbana kwembobo ethwala enkulu yomzimba kufanele kuhlolwe ngaphambi kokuhlanganiswa.Kukhona nezidingo zokujikeleza kanye ne-cylindricity.Uma yeqa umkhawulo, ayivunyelwe.Uma ingaphakathi komkhawulo, sebenzisa indlela yokugaya (okungukuthi, sebenzisa inani elifanele lempushana eholayo ebomvu ku-bearing pad, uyifake ku-crankshaft bese uyizungezisa, bese ususa ikhava yokufaka ukuze uhlole iphedi lokuthwala. izingxenye zikhishwe, ukuguqulwa kosayizi kuyalinganiswa ukuze kuqinisekiswe ukwethembeka kokusetshenziswa.

② Thuthukisa ukugcinwa kanye nekhwalithi yokuhlanganisa yamabheringi, futhi ulawule ngokuqinile izinga lokudlula lezinduku zokuxhuma.Thuthukisa ikhwalithi yehinge yokuthwala, qinisekisa ukuthi ingemuva lokuthwala libushelelezi futhi alinawo amachashazi, namaqhubu okumisa aphelele;inani le-self-bounce liyi-0.5-1.5mm, elingaqinisekisa ukuthi isihlahla esithwalayo sihlanganiswe ngokuqinile nembobo yesihlalo esithwalayo ngokuqina kwayo ngemva komhlangano;entsha 1. Zonke izinduku zokuxhuma ezindala ziyadingeka ukukala ukufana kwazo nokusonteka, futhi izinduku zokuxhuma ezingafanelekile zivinjelwe ukungena emotweni;isiphetho ngasinye sezihlahla ezithwalayo ezingaphezulu naphansi ezifakwe esihlalweni esithwalayo kufanele zibe phezulu ngo-30-50mm kunendiza yesihlalo esithwalayo, ngaphezu kwalokho Inani lingaqinisekisa ukuthi ukuthwala kanye nesihlalo esithwalayo kuhambisana ngokuqinile ngemva kokuqinisa ama-cap bolts. ngokuya nge-torque eshiwo, ikhiqiza amandla anele okuzikhiya aqinile, ukuthwala ngeke kuxege, umphumela wokukhipha ukushisa muhle, futhi ukuthwala kuvinjelwa ekukhipheni nasekugqokeni;indawo yokusebenza yebheringi ayikwazi ukumataniswa ngokuklwebha u-75% kuya ku-85% wezimpawu zokuthintana kufanele zisetshenziswe njengezinga lokulinganisa, futhi imvume efanelekile phakathi kwebheringi nejenali kufanele ihlangabezane nezidingo ngaphandle kokukhuhla.Ngaphezu kwalokho, qaphela ukubheka izinga lokucubungula lamajenali we-crankshaft nama-bearings ngesikhathi sokuhlanganiswa, futhi usebenzise ngokuqinile imininingwane yenqubo yokulungisa ukuvimbela ukufakwa okungafanele ngenxa yezindlela zokufaka ezingafanele kanye ne-torque engalingani noma engahambisani namabhawodi okuzala, okuholela ekuguqeni ukucindezeleka Ukugxila, okuholela ekulimaleni kokuqala kokuthwala.

Yenza amasheke ezihlahleni ezintsha ezithengiwe.Gxila ekulinganiseni umehluko wokujiya wesihlahla esithwalayo kanye nosayizi wokuvuleka kwamahhala, futhi uhlole ikhwalithi yendawo ngokubukeka.Ngemuva kokuhlanza nokuhlola ama-bearings amadala esesimweni esihle, umzimba wokuqala, i-crankshaft yasekuqaleni, nama-bearings asekuqaleni ayahlanganiswa futhi asetshenziswe ku-situ.

Qinisekisa ukuhlanzeka kokuhlanganiswa kwenjini kadizili namafutha enjini.Thuthukisa ukusebenza kwemishini yokuhlanza, ulawule ngokuqinile ikhwalithi yokuhlanza, futhi uthuthukise ukuhlanzeka kwezingxenye ezahlukahlukene zezinjini zikadizili.Ngesikhathi esifanayo, imvelo yendawo yomhlangano yahlanzwa futhi kwenziwa isembozo sothuli se-cylinder liner, okwathuthukisa kakhulu ukuhlanzeka komhlangano wenjini ye-diesel.

③Khetha ngokunengqondo futhi ugcwalise uwoyela wokugcoba.Ngesikhathi sokusetshenziswa, amafutha okugcoba nge-low surface tension yefilimu yamafutha kufanele akhethwe ukuze kuncishiswe umthelela wokugeleza kwamafutha lapho ama-bubbles omoya akhiwe ewa, angavimbela ngokuphumelelayo ukuthwala i-cavitation;izinga le-viscosity lamafutha okugcoba akufanele likhuphuke ngokuthanda, ukuze lingakhulisi umthamo wokuthwala.Ukuthambekela kokupheka kwenjini;indawo yamafutha okugcoba enjini kufanele ibe phakathi kwebanga elijwayelekile, uwoyela wokugcoba kanye namathuluzi okugcwalisa uphethiloli kufanele ahlanzeke ukuvimbela noma yikuphi ukungcola namanzi ukuba angangeni, futhi ngesikhathi esifanayo aqinisekise umphumela wokuvala ingxenye ngayinye yenjini.Naka ukuhlolwa okuvamile nokushintshwa kwamafutha okugcoba;indawo lapho uwoyela wokugcoba ugcwaliswa khona kufanele ingabi khona ukungcola kanye neziphepho zesihlabathi ukuze kuvinjelwe ukungena kwazo zonke izinto ezingcolisayo;akuvunyelwe ukuxuba amafutha okugcoba ezimfanelo ezahlukene, amamaki e-viscosity ahlukene kanye nezinhlobo ezahlukene zokusetshenziswa.Isikhathi sokuna akufanele sibe ngaphansi kuka-48h.

④ Sebenzisa futhi ugcine injini ngendlela efanele.Lapho ufaka i-bearing, i-shaft kanye nendawo ehambayo ye-bearing kufanele ifakwe ngamafutha enjini ahlanzekile womkhiqizo oshiwo.Ngemva kokuba amabheringi enjini ephinde afakwa, cisha inkinobho kaphethiloli ngaphambi kokuba uqale okokuqala, sebenzisa isiqalisi ukushayela injini ukuba ingasebenzi izikhathi ezimbalwa, bese uvula futhi uvule inkinobho kaphethiloli lapho igeji yomfutho kawoyela wenjini ibonakala. isibonisi, bese ubeka i-throttle phakathi nendawo nesivinini esiphansi ukuze uqalise injini.Bheka ukusebenza kwenjini.Isikhathi sokungenzi lutho asikwazi ukudlula imizuzu emi-5.Yenza umsebenzi omuhle ekusebenzeni komshini omusha kanye nenjini ngemva kokulungiswa kabusha.Ngesikhathi sokugijima, akuvunyelwe ukusebenza ngaphansi kwesimo sokunyuka okungazelelwe nokuncipha komthwalo kanye nesivinini esikhulu isikhathi eside;Ingavalwa kuphela ngemva kwemizuzu engu-15 yokusebenza ngesivinini esiphansi ngaphansi komthwalo, ngaphandle kwalokho ukushisa kwangaphakathi ngeke kuhlakazwe.

Lawula ngokuqinile izinga lokushisa lokuqala lesitimela futhi ukhuphule isikhathi sokunikezwa kukawoyela sokuqala.Ebusika, ngaphezu kokulawula ngokuqinile izinga lokushisa lokuqala lesitimela, isikhathi sokunikezwa kukawoyela kufanele futhi senyuswe ukuze kuqinisekiswe ukuthi uwoyela ufinyelela kumapheya okungqubuzana enjini kadizili futhi kuncishiswe ukungqubuzana okuxubile kwepheya ngalinye lokungqubuzana lapho injini kadizili iqala. .Ukushintshwa kwesihlungi sikawoyela.Lapho umehluko wengcindezi phakathi kwengaphambili nangemuva kwesihlungi sikawoyela ufinyelela ku-0.8MPa, izoshintshwa.Ngesikhathi esifanayo, ukuze kuqinisekiswe umphumela wokuhlunga kwamafutha, isihlungi samafutha kufanele sishintshwe njalo ukuze kuncishiswe okuqukethwe kokungcola emafutheni.

Qinisa ukuhlanzwa nokugcinwa kwesihlungi samafutha kanye nedivayisi yokungenisa umoya ye-crankcase, bese ubuyisela isici sokuhlunga ngesikhathi ngokwemiyalelo;qinisekisa ukusebenza okuvamile kwesistimu yokupholisa injini, lawula izinga lokushisa elivamile lenjini, vimbela irediyetha ukuba “ibilise”, futhi wenqabele ngokuqinile ukushayela ngaphandle kwamanzi okupholisa; Ukukhetha uphethiloli okufanele, ukulungiswa okunembile kwesigaba sokusatshalaliswa kwegesi kanye nesikhathi sokuthungela, njll. ., ukuvimbela ukusha kwenjini okungavamile: hlola ngesikhathi futhi ulungise isimo sobuchwepheshe se-crankshaft nama-bearings.

Yenza njalo ukuhlaziywa kwe-ferrographic kawoyela wenjini ukuze unciphise izingozi.Kuhlanganiswe nokuhlaziywa kwe-ferrographic kawoyela wenjini, ukuguga okungavamile kungabonwa kusenesikhathi.Ngokwephethini yokuhlaziywa kwe-ferrographic kawoyela wenjini, ukwakheka kwezinhlamvu ezilumayo kanye nezindawo ezingaba khona kunganqunywa ngokunembile, ukuze kuvinjwe izinkinga ngaphambi kokuba zenzeke futhi kugwenywe ukwenzeka kwengozi yeshaft eshiswa ngamathayili.
