Yemhando yepamusoro Diesel Fuel Injection Pump BH4PN120R Injini Zvikamu zve WEICHAI TD226B-4

Sechikamu chakakosha chekukwesha chepombi yegiya remafuta, maitiro ekubereka ane zvakakosha pakuita kwekushanda, kuvimbika uye hupenyu hwepombi yemafuta. Pombi yemafuta inotakura svikiro kune yakaderera viscosity mafuta, mumutoro wakakwira uye nekumhanyisa mamiriro, hushoma hwemafuta firimu ukobvu hweiyo inotsvedza inotsvedza yakanyanya kutetepa, zvakanyanya kurongeka kwakafanana kwehukuru nekushata kwepasi kwezvikamu, zviri nyore kupfeka uye kubvaruka. uye nokudaro zvinotungamirira kukukundikana kwepombi yemafuta inotsvedza. Mune lubricating yepakati viscosity uye kurodha imwe mamiriro, kutsvedza kutakura clearance ratio (inoreva kune inotsvedza inotsvedza uye shaft dhayamita clearance uye shaft dhayamita reshiyo) ndiyo inonyanya pesvedzero yehudiki hwefirimu ukobvu, hunozokanganisa kutakura. capacity.

Naizvozvo, kuitira kugadzirisa dambudziko rekuti mabheji ekutsvedza emapombi emafuta epombi anowanzo kupfekwa nekuda kwekuonda kwefirimu remafuta, izvo zvinotungamira mukutadza kwemabheji anotsvedza pasi pemutoro wakakwira uye nekumhanya kwemamiriro, uye nekuona iyo chokwadi chekuti clearance ratio ndiyo inonyanya kupesvedzera chinhu cheshoma mafuta firimu ukobvu hwemabhengi anotsvedza, mabheji anotsvedza eimwe mhando yemapombi emafuta anotorwa sechinhu chekutsvagisa kuti chidzidzwe uye yakaongororwa nePumpLinx simulation kuti ione hudiki hwemafuta firimu ukobvu hwemabheya, mutoro wekutakura mutoro, kudzvanywa uye kugovera tembiricha yemabhengi ane mareshiyo akasiyana emvumo. Iwo mashoma emafuta firimu ukobvu, mutoro wekuremerwa, kudzvanywa uye tembiricha kugoverwa kwemabhengi ane akasiyana mareshisheni emvumo anoongororwa nePumpLinx simulation. Flexural deformation yegiya shaft yeimwe pombi yemafuta inoongororwa, uyezve hukama huripo pakati peiyo inotsvedza inotakura clearance ratio uye hudiki hwemafuta efirimu ukobvu, mutoro wekuremerwa, tembiricha yekubereka uye kugovera kwekutenderera uye radial kumanikidzwa kunoongororwa pasi pemamiriro maviri ekushanda. , kureva, kukurumidza kukurumidza uye kukurumidza kwepombi, maererano. Mhedzisiro yacho inoratidza kuti: pachiyero chakafanana chekubvumidza, iyo inotsvedza inotakura inokwira kana mafuta efirimu ukobvu kunoderera; apo chiyero chekuregererwa chinoderera, simba rekutakura rinowedzera; apo kukurumidza kunowedzera, simba rekutakura rinowedzera; maererano nezvese kuparadzirwa kwekumanikidza uye tembiricha inokwira, iyo yakanakisa mamiriro inowanikwa apo yakakodzera clearance ratio yegiya shaft uye inotsvedza inotakura idiki.
