I-Diesel Injector Fuel Injector 0445120343 ihambisana ne-Bosch injector WEICHAI WD615 WD10 - EU 4

Inqubo yokusebenza ye-injector

Enqubweni yokusebenza, inqubo yomjovo womjovo wephampu ingahlukaniswa izigaba ezimbili: umjovo wangaphambili kanye nomjovo omkhulu, futhi ungahlukaniswa ube umjovo wangaphambili, ukuphela komjovo wangaphambi komjovo, umjovo omkhulu, ukuphela komjovo omkhulu kanye Igumbi likawoyela elinengcindezi ephezulu Kunezinqubo ezi-5 zokuthatha uwoyela. Isikhathi sokujova uphethiloli kanye nenani lomjovo kaphethiloli kulawulwa ngokuhlanganyela yi-plunger eyisizayo, ivalvu yenaliti yokujova uphethiloli, intwasahlobo yokubuya kwevalvu inaliti yomjovo kaphethiloli, isibambisi sevalvu yokujova uphethiloli kanye nevalvu yokulawula i-electromagnetic.
(1) Umjovo wangaphambili
Lapho ingxenye eqondile yekhamera ithinta ingalo ye-rocker, uhlelo lokulawula i-elekthronikhi lunikeza amandla ku-valve yokulawula i-electromagnetic, ukuze i-valve yenaliti ye-electromagnetic control valve ihambe iye kwesokunxele, inqamule iphaseji phakathi kwegumbi elinomfutho ophezulu futhi. iphasishi likawoyela onengcindezi ephansi, ngasikhathi sinye, ikholomu kawoyela wephampu Ngaphansi kwesenzo sengalo ye-rocker, ipulaki ihambela phansi ngokumelene namandla anwebekayo omthombo obuyayo we-plunger kawoyela wepompo, ukuze umfutho kawoyela Igumbi likawoyela elinengcindezi ephezulu likhuphuka ngokushesha. Lapho umfutho kawoyela ukhuphukela ku-18MPa, ukuphokophela phezulu okukhiqizwe uphethiloli endaweni yekhoni emaphakathi nevalve yenaliti yomjovo kukhulu kunamandla okuqinisa angaphambili entwasahlobo yokubuya yevalve yenaliti yomjovo, kanye nevalve yenaliti yomjovo. izophushelwa phezulu ukuze kuqalwe ukujova kwangaphambili.
(2) Ukuphela komjovo wangaphambili
Ngemva kokuqala komjovo wangaphambili, inaliti yomjovo kaphethiloli iyaqhubeka nokuya phezulu. Lapho ikhamera ijika ngaphezu kwe-1/3 ye-stroke yomjovo kaphethiloli, indawo engezansi yomshini wokupholisa inaliti yokujova ingena embotsheni yokupholisa inaliti yokujova uphethiloli, bese ingaphezulu kwenaliti yomjovo kaphethiloli. i-valve yenaliti yomjovo ngokusebenzisa igebe elincane. Ngale ndlela, kwakhiwa okuthiwa "i-hydraulic gasket" phezulu kwe-valve inaliti yokujova uphethiloli, okuvimbela i-valve inaliti yokujova uphethiloli ukuthi iqhubeke nokuhambela phezulu, ukuze inani langaphambi kokujova likaphethiloli lilinganiselwe. Njengoba i-pump plunger iqhubeka yehla, umfutho kawoyela egunjini likawoyela elinomfutho ophezulu uyaqhubeka nokukhuphuka. Lapho ingcindezi kawoyela ifinyelela inani elishiwo, ngemva kokuba i-plunger eyisizayo iqhubekela phansi ngaphansi kwesenzo sikaphethiloli wokucindezela okukhulu, umthamo wegumbi likawoyela elinomfutho ophezulu uyanda ngokuzumayo. ukwanda, umfutho kaphethiloli wehla ngaso leso sikhathi. Ngalesi sikhathi, ukuphonsela phezulu endaweni ye-cone maphakathi nenaliti yomjovo kaphethiloli kuncipha ngokufanele, futhi inaliti yomjovo kaphethiloli iqala kabusha ngaphansi kwesenzo sokubuya kwentwasahlobo yenaliti yomjovo kaphethiloli (amandla okunwebeka ayanda ngenxa yokucindezelwa i-plunger eyisizayo), kanye ne-Pre-jove Oil isiphelile.
