(1) Paunenge uchigadzira, iva nechokwadi chehutano hwegungano

Pakuunganidza crankshaft yeinjini yedhiziri, nhanho imwe neimwe inofanira kunge yakanyatsojeka. Usati waisa crankshaft, chenesa crankshaft uye uchenese mugero wemafuta we crankshaft nemhepo inodzvanywa. Mamwe ma crankshaft ane maburi eparutivi uye akavharika nema screws. Izvo zvisina kuchena zvakaparadzaniswa nemafuta nekuda kweiyo centrifugal simba ichaunganidza pano. Bvisa screws uye uchenese zvakanaka.

Pakuunganidza crankshaft, zvinodikanwa kusarudza mabhengi emhando yepamusoro uye kuve padanho rakafanana nere crankshaft kuti ive nechokwadi chekuti nzvimbo yekubata nejenari inodarika 75%. Iwo mapoinzi ekusangana anofanirwa kupararira uye anowirirana (nekuongorora kutakura). The tightness inofanira kuva yakakodzera. Mushure mekusimbisa mabhoti maererano neiyo torque yakatarwa, mabhoti anofanira kutenderera zvakasununguka. Kunyanya kusimba kuchawedzera kupfeka kwe crankshaft uye kubereka, uye kuregedzera kunokonzera kurasikirwa kwemafuta uye kuwedzera kupfeka.

Iyo axial clearance ye crankshaft inogadziriswa ne thrust pad. Paunenge uchigadzirisa, kana iyo axial gap yakakura kwazvo, iyo yekusundira pad inofanira kutsiviwa kuti ive nechokwadi chekuti gap riri mukati meimwe nhanho. Zvikasadaro, crankshaft inodzokera kumashure kana mota ichikwira nekudzika, zvichikonzera kusagadzika kweiyo yekubatanidza tsvimbo inotakura uye crankshaft.


(2) Ita shuwa kunaka uye kuchena kwemafuta ekuzora

Shandisa mafuta ekuzora emhando yakakodzera. Iyo yakakodzera dizeli injini yemafuta inofanirwa kusarudzwa zvichienderana nekuremerwa kweinjini yedhiziri. Mafuta emhando ipi neipi yegiredhi achachinja panguva yekushandiswa. Mushure meimwe mileage, kuita kwacho kuchadzikira, zvichikonzera matambudziko akasiyana kune injini yedhiziri. Munguva yekushanda kweinjini yedhiziri, iyo yakakwira-kudzvanya isina kupiswa gasi, hunyoro, asidhi, sarufa uye nitrogen oxides mukamuri yekupisa ichapinda mu crankcase kuburikidza nemukaha uripo pakati pepiston ring uye cylinder madziro, uye kusanganisa nehupfu hwesimbi inopfekwa. kunze nepamativi kuita dope. Kana huwandu hwacho hushoma, huchamiswa mumafuta, uye kana huwandu hwacho hwakura, huchadonha kubva mumafuta, izvo zvinovhara sefa nemakomba emafuta. Kana iyo sefa yakavharwa uye oiri isingakwanise kupfuura nepakati pesefa element, inopwanya iyo sefa chinhu kana kuvhura vharavhavhavha, uye kupfuura nepakati pevharuvhu, ichidzosa tsvina kuchikamu chekuzora, ichiwedzera kusvibiswa kwemafuta uye kuwedzera kupfeka crankshaft. Nokudaro, mafuta anofanira kuchinjwa nguva dzose uye crankcase inofanira kucheneswa kuchengetedza mukati meinjini yedhiziri yakachena kuitira kuti crankshaft ishande zviri nani.


(3) Nyatsodzora tembiricha yekushanda yeinjini yedhiziri

Tembiricha yakabatana zvakanyanya nekuzora. Sezvo kutonhora kunowedzera, viscosity yemafuta inova yakaderera, uye firimu yemafuta haisi nyore kuumba. Chikonzero chekushisa kwakanyanya kusapisa kupisa kweiyo inotonhorera system, ngura uye kuwedzera kweiyo radiator yemvura matambudziko akajairika. Ngura uye chiyero zvinodzora kuyerera kweinotonhorera muinotonhodza system. Kuwedzeredza chiyero kunoderedza kutenderera kuyerera kwemvura, kuderedza kupisa kwekupisa, uye kuita kuti injini yedhiziri iwedzere; panguva imwecheteyo, kuderedzwa kwechikamu chegeji yemvura kuchawedzera kudzvinyirirwa kwemvura, zvichikonzera kubuda kwemvura kana kuzadza mvura Kupfachukira, kusakwana kwemvura inotonhorera, nyore kuzarura hari; uye oxidation yemvura inotonhorera inoumbawo zvinhu zvine acidic, izvo zvinosvibisa zvikamu zvesimbi zve radiator yemvura uye zvinokonzera kukanganisa. Naizvozvo, radiator yemvura inofanirwa kucheneswa nguva nenguva kubvisa ngura uye chiyero mairi kuti ive nechokwadi chekushanda kwakajairika kwe crankshaft. Iyo tembiricha yakawandisa yeinjini yedhiziri crankshaft ine hukamawo nenguva yejekiseni yemafuta, saka nguva yejekiseni yemafuta inofanirwa kugadziridzwa nemazvo.
