Umjovo Omusha Kadizili Osezingeni eliphezulu 28229873 33800-4A710 Common Rail Injector we Delphi Hyundai 2.5 CRDI Engine Spare Parts

Yenziwe ngensimbi enekhwalithi ephezulu, imvume yayo ye-cylindrical eshelelayo ingu-0.001mm-0.0025mm kuphela, etholwe ngomshini wokunemba okuphezulu noma izinketho zokugaya, futhi ukuhlanganisa okuhlukile komjovo kaphethiloli akushintsheki. Uma igebe likhulu kakhulu, ingcindezi yomjovo izokwehla futhi izinga lokufuthwa lizowohloka; Igebe lincane kakhulu, futhi i-valve yenaliti kulula ukuyifaka. I-annular cone (i-cone-bearing-bearing cone) maphakathi ne-valve yenaliti itholakala emgodini wamafutha we-annular womzimba we-valve yenaliti, futhi umsebenzi wayo ukumelana ne-axial thrust ekhiqizwa ukucindezela kukawoyela ukwenza i-valve yenaliti inyuke. Ikhoni esekupheleni kwevalve yenaliti (ikhoni yokuvala) ifanelana nomzimba wevalvu yenaliti ukuze kuvalwe imbobo engaphakathi yomjovo.

Ingxenye engenhla ye-valve yenaliti inehlombe le-convex, lapho i-valve yenaliti ivaliwe, ibanga h phakathi kwehlombe nobuso bokuphela obuphansi bomzimba womjovo wukuphakama okuphezulu kwe-valve yenaliti, futhi ubukhulu bayo bunquma inani le-valve yenaliti. umjovo kaphethiloli, ngokuvamile H=0.4mm-0.5mm. Kunamaphinikhodi angu-1-2 okuthola u-8 lapho kuhlangana khona imbobo yenaliti yenaliti kanye nomjovo ukuvimbela umzimba wevalvu yenaliti ukuthi ungajikelezi ukugwema ukungahambi kahle kwembobo yokungena kawoyela.

Lapho umjovo usebenza, udizili onomfutho ophezulu ophuma empompini yokujova, ngokusebenzisa ipayipi likawoyela elihlanganyelwe lingene embotsheni kawoyela emzimbeni womjovo, bese lingena emgodini kawoyela ophakathi nendawo phakathi kwevalve yenaliti, isebenza ngokucindezela. -i-cone ethwele i-valve yenaliti, eyenza i-axial thrust eya phezulu ku-valve yenaliti, uma lokhu kuhlohla kukukhulu kunokucindezela kwangaphambili kwesiphethu somlawuli womjovo, i-valve yenaliti ikhuphuka ngokushesha, ivule imbobo yomjovo, futhi uphethiloli we-diesel wokucindezela okuphezulu ujovwa ngokushesha ekamelweni elivuthayo. Lapho iphampu yomjovo kaphethiloli iyeka ukunikeza uwoyela, ingcindezi ephaseji likawoyela elinengcindezi ephezulu yehla ngokushesha, futhi ivalve yenaliti ibuyela endaweni ngesikhathi ngaphansi kwesenzo somfutho olawula intwasahlobo, futhi imbobo yomjovo iyavalwa ukuze kumiswe uphethiloli. umjovo.

Inani elincane likaphethiloli wedizili elingena emgodini kawoyela we-annular womzimba we-valve yenaliti ligeleza liye kumfutho olawula ukuphela kwentwasahlobo ngegebe eliphakathi kwezindawo zokukhwelana zezithandani zomjovo, lingene epayipini lokubuyisela uwoyela, bese ligeleza libuyele kusihlungi, okuyisici. esetshenziselwa ukugcoba umbhangqwana womjovo kaphethiloli.

Ingcindezi yokuvula (ingcindezi yokujova) ye-valve yenaliti incike ekulayisheni kuqala kwentwasahlobo yokulawula. Izinjini ezihlukene zinezidingo ezihlukile zokucindezela komjovo, ezingalungiswa ngesikulufu esilawula ukucindezela, ingcindezi iyanda lapho isikulufa futhi yehle lapho isikrufu.
