Isijojo sikadizili sekhwalithi ephezulu 367-4293 3674293 isitofu sikadizili se-CAT C9.3 Ingxenye eyisipele

Izinsalela eziphukile zephini le-dowel ngezinye izikhathi kunzima ukuphuma emgodini we-dowel we-injector wezindlu. Kulesi simo, ngokuvamile kuyadingeka ukufaka iphinikhodi ye-dowel noma i-dowel pin. Ngokuvamile, hhayi ezimeni eziphuthumayo, umzimba wenaliti yomlomo akufanele ufakwe kuphela iphinikhodi. Ngenxa yokuthi ikepisi eliqinile lombhobho liyaqiniswa uma kufakwa iphinikhodi yedowel eyodwa kuphela, umzimba wenaliti yomlomo ungase uzungeze iphinikhodi. Ngale ndlela, i-valve yenaliti ye-nozzle kanye nembobo ye-tappet yegobolondo lokujova akuqondakali kahle kalula. Uma ingahlehliswanga kahle, amandla asetshenziswa yi-nozzle tappet esiqwini somsila wevalvu yenaliti kulula ukukhiqiza ingxenye ethile ye-radial. Ukukhanya, i-valve yenaliti emzimbeni we-valve yenaliti eya phezulu naphansi kulula ukuyivimba into, ukulungisa iphutha kungase kugcine kujwayelekile, kodwa inkinga engaba khona akufanele indiva, ibucayi, i-valve yenaliti emzimbeni we-valve yenaliti phezulu naphansi. izinwele ezinde, ukulungisa iphutha kungase kubonakale njengento econsayo. Ngomzimba we-valve yenaliti ongenawo ama-annular grooves, kungase kube nokuhlukana okukhulu phakathi kwembobo ye-oyela yevalve yenaliti kanye nembobo kawoyela yegobolondo lomjovo lapho iphinikhodi yokumisa ingafakiwe. Nakuba kungeke kuthinte ukusha kukadizili, kuzoba nendawo encane enqamula ingxenye yembobo kawoyela, okuzodala umthelela othile enanini lomjovo kawoyela. Ngesikulufu sokulungiswa sokuphakamisa i-valve yesikhala somsindo, esifana nochungechunge lomjovo we-diesel fuel, ngaphambi kokuhlanganisa umbhangqwana we-nozzle, kufanele uqale ngokukhulula isikulufu sokulungisa i-lift, ukuze ungafaki umbhangqwana we-nozzle uqinise ikepisi lombhobho, ukulungiswa kokuphakamisa inaliti yomlomo isikulufu kanye nezinye izingxenye deformation. Ngaphezu kwalokho, lapho umbhangqwana we-nozzle ufakwe ku-cap ye-nozzle eqinile, Iphinikhodi e-flange ye-valve ye-nozzle ye-nozzle kanye nephini lokubeka endaweni eqinile kufanele iqondaniswe, futhi ipuleti lombhobho nomzimba we-valve yenaliti akufanele kube. behlukene ngaso sonke isikhathi.
