I-Diesel Injector Fuel Injector 0445120289 Bosch ye-Cummins Isbe Isde Qsb6.7

Esinye isibonelo i-double-hole close fuel injector esetshenziswa injini ye-diesel engu-6120.I-diameter yembobo yomjovo ingu-0.42mm futhi ingcindezi yomjovo ingu-17.5M Pa. Umgomo wokusebenza womjovo yenaliti ye-shaft ufana naleyo yomjovo wembobo, isakhiwo kuphela esihlukile: ngaphansi kwekhoni yokuvala ekugcineni okuphansi. we-valve yenaliti, inaliti ye-shaft iphuma emgodini, futhi ukwakheka kwayo kungahle kuguqulwe i-conical noma i-cylindrical, ukuze umlomo wombhobho ube yi-slit eyindilinga.Ngale ndlela, ikholomu yomjovo izoba yikhoni engenalutho noma ikholomu.Ubukhulu besigaba sesiphambano sembobo yomjovo kanye ne-engeli yekhoni yomjovo incike ekuphakameni nasekumeni kwenaliti ye-shaft, ngakho-ke ukucutshungulwa komumo wenaliti ye-shaft kuyadingeka ukuthi kunembile kakhulu.Idayamitha yomjovo womjovo wenaliti yomphini inkulu (imvamisa i-1 ~ 3mm), ingcindezi yomjovo iphansi (imvamisa i-10 ~ 14MPa), ikhono lokuzihlanza liqinile (imbobo yomjovo akulula ukunqwabelanisa ikhabhoni nokuvinjwa), izici zomjovo zinhle (hlangabezana izidingo zomjovo kawoyela omncane ekuqaleni, umjovo kawoyela omningi phakathi kanye nomjovo kawoyela omncane kamuva), Ifanele igumbi lokusha le-vortex negumbi lokuvutha langaphambi komlilo elinemfuneko ephansi kwikhwalithi yesihlungi sikadizili.Isibonelo, i-diameter ye-nozzle ye-4125A4 injini ye-diesel ingu-1.5mm futhi ingcindezi yomjovo ingu-12.7M Pa. Okuthathu, i-inertia ephansi yesijovo sikaphethiloli wenduku yendabuko yinde, indawo yokulawula ingcindezi intwasahlobo ikude nevalvu yenaliti, ukuze i-valve yenaliti yokukhuphuka naphansi yokunyakaza ikhule, umthelela we-valve yenaliti endaweni yokuvala uphawu uyakhuphuka, ukuzwela kokuphendula kwe-valve yenaliti kungcindezi kawoyela kuncipha.
