Kukuvadzwa kwekutanga kwemabhengi ekutsvedza kwakajairika pane kutakura kupera simba, saka zvakakosha kudzivirira kukuvara kwekutanga kumabhengi ekutsvedza.Kugadzirisa kwakaringana kwemabhengi ekutsvedza inzira inoshanda yekudzikisa kukuvara kwekutanga kumabhengi uye vimbiso yakavimbika yekurebesa hupenyu hwekubereka.Naizvozvo, mukugadzirisa kwezuva nezuva uye kugadzirisa kweinjini, kutarisisa kunofanirwa kubhadharwa kune chitarisiko uye chimiro cheiyo alloy pamusoro, kumashure, kumagumo uye kumucheto makona ekutakura.Matanho ekuvandudza mamiriro ekushanda ekutakura, uye teerera kune kudzivirira kwekutanga kukuvara kune inotsvedza bearing.

① Nyatsoyera coaxiality uye kutenderera kwegomba guru rekutakura remuviri weinjini yedhiziri.Kune kuyerwa kweiyo coaxiality yegomba guru rekutakura remuviri weinjini, coaxiality yemuviri weinjini yedhiziri iyo inofanirwa kuyerwa ndeyechokwadi, uye kubuda kwe crankshaft kunoyerwa panguva imwe chete, kuitira kuti usarudze ukobvu. yegwenzi rinotakura kuita kuti gaka rekuzora mafuta rienderane mune imwe neimwe axis chinzvimbo.Ikoko injini yedhiziri yakaiswa pasi pekutenderedza mataira, mota dzinobhururuka, nezvimwewo, coaxiality yegomba guru rinotakura remuviri rinofanira kuedzwa pamberi pegungano.Kune zvakare zvinodiwa zvekutenderera uye cylindricity.Kana ikadarika muganhu, inorambidzwa.Kana iri mukati memuganho, shandisa nzira yekukuya (kureva kuti, shandisa huwandu hwakakodzera hwehupfu dzvuku pabearing pad, uise mu crankshaft woitenderedza, wobva wabvisa chivharo chekutakura kuti utarise pedhi yekubereka. Mushure mezvo. zvikamu zvakakweshwa, shanduko yehukuru inoyerwa kuve nechokwadi chekuvimbika kwekushandisa.

② Kuvandudza kuchengetedza uye kusangana kwemhando yemabhengi, uye kunyatsodzora chiyero chekupfuura chekubatanidza tsvimbo.Kuvandudza hinge yemhando yekutakura, iva nechokwadi chekuti kumashure kwekubereka kwakatsetseka uye kusina mavara, uye mabhupu ekumisa akasimba;kuwanda kwe-self-bounce ndeye 0.5-1.5mm, iyo inogona kuve nechokwadi chokuti gwenzi rinotakura rakanyatsogadzirirwa negomba rechigaro chekutakura nehutu hwayo mushure mekusangana;nokuda kwezvitsva 1. Zvose zvekare zvinosungirirana zvinotarisirwa kuyera kufanana kwavo uye kutenderera, uye matanda asina kukodzera akabatanidzwa anorambidzwa kupinda pamotokari;magumo ega ega epamusoro uye epasi anotakura mabhushi akaiswa muchigaro chekutakura anofanira kunge ari 30-50mm yakakwirira kudarika ndege yechigaro chekutakura, yakakwirira kudarika Nhamba inogona kuvimbisa kuti kutakura uye chigaro chekutakura zvakanyatsoenderana mushure mekusimbisa mabhoti anotakura. zvinoenderana neiyo torque yakatsanangurwa, ichigadzira inokwana frictional yekuzvivharira simba, iyo kutakura haizosunungure, kupisa kwekupisa mhedzisiro yakanaka, uye kutakura kunodzivirirwa kubva pakubvisa uye kupfeka;nzvimbo yekushanda yekutakura haigoni kuenzaniswa nekuchera 75% kusvika ku85% yezvinyorwa zvekubatana zvinofanira kushandiswa seyero yekuyera, uye kubvumirwa kwakakodzera pakati pekutakura nejenari kunofanira kusangana nezvinodiwa pasina kuputika.Uye zvakare, teerera kutarisa kunaka kwekugadzirisa kwe crankshaft majenari uye mabearings panguva yekuungana, uye kunyatso shandisa maitiro ekugadzirisa maitiro kudzivirira kuisirwa kusiri iko nekuda kweisina kurongeka nzira yekuisa uye isina kuenzana kana isingaenderane torque yekubereka mabhoti, zvichikonzera kubhenda deformation uye. stress Concentration, zvichiita kuti kukuvara kwekutanga kubereka.

Itai macheki pamatengo matsva akatengwa.Tarisa pakuyera mutsauko wehukobvu hwegwenzi rinotakura uye saizi yekuvhura kwemahara, uye ongorora iyo yepamusoro mhando nechitarisiko.Mushure mekuchenesa uye kuyedza mabhengi ekare ari mumamiriro akanaka, muviri wepakutanga, crankshaft yepakutanga, uye mabhengi ekutanga anounganidzwa uye anoshandiswa mu situ.

Ita shuwa kuchena kwedhiziri injini musangano uye mafuta einjini.Kuvandudza mashandiro emidziyo yekuchenesa, nyatso kudzora kunaka kwekuchenesa, uye kugadzirisa hutsanana hwezvikamu zvakasiyana zveinjini dzedhiziri.Panguva imwecheteyo, nharaunda yenzvimbo yegungano yakacheneswa uye cylinder liner dust cover yakagadzirwa, iyo yakavandudza zvakanyanya kuchena kwejini injini yedhiziri.

③Sarudza zvine musoro uye uzadze mafuta ekuzora.Panguva yekushandiswa, mafuta ekuzora ane kuderera kwepamusoro kwefirimu yemafuta inofanira kusarudzwa kuti kuderedze kukanganiswa kwemafuta ekuyerera apo iyo yakaumbwa mhepo inoputika inodonha, iyo inogona kubudirira kudzivirira kutakura cavitation;iyo viscosity giredhi yemafuta ekuzora haifanirwe kuwedzerwa pamadiro, kuitira kuti isawedzere kubereka simba.Maitiro ekubikira injini;iyo mafuta ekuzora pamusoro peinjini inofanirwa kunge iri mukati meyakajairwa, mafuta ekuzora uye maturusi ekuwedzera anofanirwa kuve akachena kudzivirira chero tsvina nemvura kuti isapinda, uye panguva imwechete ive nechokwadi chekuisa chisimbiso chechikamu chimwe nechimwe cheinjini.Teerera kuongorora nguva dzose uye kuchinjwa kwemafuta ekuzora;nzvimbo iyo mafuta ekuzora anozadzwa nayo inofanira kunge isina kusvibiswa uye madutu ejecha kudzivirira kupindira kwezvinhu zvose zvinosvibisa;zvinorambidzwa kusanganisa mafuta ekuzora emhando dzakasiyana, akasiyana viscosity mamakisi uye akasiyana marudzi ekushandisa.Nguva yekunaya haifanire kunge iri pasi pe48h.

④ Shandisa uye chengetedza injini nemazvo.Paunenge uchiisa kubereka, shaft uye nzvimbo inofamba yekutakura inofanira kuputirwa nemafuta ejini akachena emhando yakataurwa.Mushure mekunge mabheji einjini aiswazve, dzima switch yemafuta usati watanga kekutanga, shandisa chinobatisa kutyaira injini kuti isashande kwenguva shoma, wobva wabatidza nekubatidza switch yemafuta kana geji yemafuta einjini ichiratidza. iyo inoratidzira, uye isa throttle pakati uye yakaderera kumhanya chinzvimbo kuti utange injini.Tarisa kushanda kweinjini.Idling nguva haigoni kudarika 5 maminitsi.Ita basa rakanaka mukushanda-mukushanda kwemuchina mutsva uye injini mushure mekugadzirisa.Munguva yekumhanya-munguva, zvinorambidzwa kushanda pasi pemamiriro ekukurumidza kuwedzera uye kuderera kwemutoro uye kukurumidza kukurumidza kwenguva refu;Inogona kuvharwa chete mushure memaminitsi gumi nemashanu ekushanda kwakaderera pasi pemutoro, kana zvisina kudaro kupisa kwemukati hakuzoparadzwi.

Nyatsodzora tembiricha yekutanga ye locomotive uye wedzera iyo mafuta ekupa nguva yekutanga.Munguva yechando, pamusoro pekunyatso kudzora tembiricha yekutanga yelocomotive, nguva yekupihwa kweoiri inofanirwawo kuwedzerwa kuti ive nechokwadi chekuti oiri inosvika pakupokana kweinjini yedhiziri uye kuderedza kukweshera kwakasanganiswa kwega ega friction panotanga injini yedhiziri. .Oil filter replacement.Kana mutsauko wekumanikidza pakati pemberi uye kumashure kwemafuta sefa unosvika 0.8MPa, inotsiviwa.Panguva imwecheteyo, kuitira kuve nechokwadi chekusefa kwemafuta, iyo sefa yemafuta inofanirwa kutsiviwa nguva nenguva kuti kuderedze kusachena kuri mumafuta.

Simbisa kucheneswa uye kuchengetedza kwemafuta sefa uye crankcase ventilation mudziyo, uye tsiva iyo sefa chinhu munguva maererano nemirairo;chengetedza kushanda kwakajairwa kweinjini yekutonhodza sisitimu, kudzora tembiricha yakajairika yeinjini, kudzivirira radiator kubva "kuvira", uye kurambidza zvakanyanya kutyaira pasina mvura inotonhorera; Kusarudzwa kwakaringana kwemafuta, kurongeka kwakaringana kwechikamu chekugovera gasi uye nguva yekubatidza, nezvimwe. ., kudzivirira kupisa kusingaite kweinjini: tarisa panguva uye gadzirisa mamiriro ehunyanzvi e crankshaft nemabhengi.

Gara uchiita ferrographic ongororo yeoiri yeinjini kuderedza tsaona.Yakasanganiswa neferrographic ongororo yeoiri yeinjini, kupfeka zvisina kujairika kunogona kuonekwa nekukurumidza.Zvinoenderana nemaitiro ekuongorora ferrographic yeoiri yeinjini, kuumbwa kweabrasive zviyo uye nzvimbo dzinogoneka dzinogona kutariswa nenzira kwayo, kuitira kudzivirira matambudziko asati aitika uye kudzivirira kuitika kwetsaona yekupisa shaft tsaona.
