Nozzle New Common Rail Injector 0433171831 & Dlla146p1339 for Injector 0445120030 & 0445120218

1. 1.Umthelela wamapharamitha wokusebenza komjovo ezicini zokuvala:

Izinto ezinjengokuguquguquka kwengcindezi yamanzi ngaphansi kwengcindezi ephezulu kanye ne-torque eqinisayo lapho i-injector ifakiwe izobangela i-eccentricity nokuthambekela kwe-valve yenaliti ngesikhathi sokulingana, okuzothinta ukusebenza komhlangano we-valve yenaliti. Ngenxa yezinga lokucubungula, ukubekezelelana kokuma nokuma kwesikhundla kubonakala ngokungenakugwenywa ebusweni bomhlangano we-valve yenaliti ngesikhathi sokucubungula. I-valve yenaliti ihlale iphindaphinda ngesikhathi senqubo yokusebenza komjovo kaphethiloli. Lezi zici zenza i-valve yenaliti ibe nokuthambekela okuncane okuhlobene nembobo yangaphakathi yomzimba we-valve yenaliti.

1. Inkambu yokushisa nokuguqulwa kokuhlanganisa inaliti yevalvu:

Umfutho ophakeme kaphethiloli esikhaleni esiphakathi kwezingxenye zokuhlanganisa i-valve yenaliti kubangela ukuwohloka okunwebekayo kwezingxenye zokuhlanganisa i-valve yenaliti. Ngesikhathi esifanayo, ngenxa yegebe elincane lokufaneleka, uketshezi lunomphumela oqinile we-viscous, izinga lokushisa loketshezi liyakhuphuka, futhi ukudluliswa kokushisa okuqinile okuwuketshezi kubangela ukuthi izingxenye ezihlanganisa inaliti zenaliti ziwohloke ngokushisa. Ukuguqulwa kwe-elastic kwenza i-valve yenaliti inciphe ibe mncane, umzimba we-valve yenaliti ukhule ube mkhulu, futhi ifilimu kawoyela esikhaleni iba mkhulu. I-thermal deformation yenza ukunwetshwa kwangaphandle kwe-valve yenaliti kukhudlwana, ukwanda okushisayo komzimba we-valve yenaliti eduze kwesiqondiso se-radial kwenza igebe libe lincane, futhi ukunwetshwa okushisayo okuhambisana nobude be-arc kwenza igebe libe likhulu, lapho yokugcina inkulu kune-arc. okokuqala, ifilimu yamafutha esikhaleni izoba mkhulu, ngaphandle kwalokho ifilimu yamafutha esikhaleni izoncipha.
