I-DLLA152PN269 Common Rail Diesel/Fuel Injector BOSCH Injector Nozzle

Ukuhlolwa Nokushintshwa Kwembobo Yomjovo

Ukuhlangana kwevalvu yenaliti kubuye kubizwe ngokuthi i-coupling nozzle ye-injector.Yakhiwe nge-valve yenaliti kanye nomzimba we-valve yenaliti ukuze wenze ukuhlanganisa okunembayo okuphezulu.Ngemva kokugaywa ngababili, ayishintsheki.Iphutha elikhulu lokuhlanganiswa kwe-valve yenaliti ukuthi imbobo ye-nozzle ivalekile futhi uphawu aluqinile.

1 Indlela yokuhlola yobuchwepheshe

(1) Indlela yokubuka yangaphandle.Isimo sobuchwepheshe bokuhlanganiswa komjovo kaphethiloli singahlulelwa ngekhwalithi ye-atomization kaphethiloli.Ngemva kokulungisa ingcindezi yomjovo, uma kukhona amachashaza enkungu noma imigqa kawoyela enogqinsi olungalingani kusifutho, ngokuvamile kuba umjovo kaphethiloli.I-coupler igugile kakhulu;lapho inkungu yamafutha isakazwa ngokungalingani noma umugqa ophakathi womugqa wamafutha ugobile, kubonisa ukuthi imbobo ye-nozzle ayihlanzekile;lapho amafutha econsa ngemva kokufafaza, kusho ukuthi ikhoni yokuvala yevalve yenaliti ayivalwanga ngokuqinile.

(2) Ukuhlolwa kokuvala.Lungisa ingcindezi yomjovo kaphethiloli womjovo kaphethiloli ube ngu-3-5MPa ngaphezu kwengcindezi evamile, futhi uhlole isikhathi esidlulile lapho ingcindezi kaphethiloli yehla isuka ku-20Pa iye ku-18Pa, okungafanele ibe ngaphansi kuka-9-12s.

2 Izinyathelo zokuphepha zokushintshwa

Ukushintshwa kokuhlanganiswa komjovo kufanele kwenziwe ngendlela elandelayo kanye nendlela: (1) Khipha isivalo somjovo kanye nenathi lokukhiya, bese ukhulula isikulufu sokulungisa.(2) Khipha isiphethu, isihlalo sasentwasahlobo kanye nephinikhodi yokukhipha ngokulandelana.(3) Bopha indawo yokuhlala yomjovo kaphethiloli ku-vise, qaqa ikepisi eliqinile lomjovo kaphethiloli, bese ukhipha umjovo kaphethiloli.(4) Hlanza izingxenye ezihlakaziwe emafutheni kadizili ahlanzekile, futhi uhlole ukuthi izingxenye ziphelele noma cha.Kudingeka ukuthi induku ye-ejector ayigobile, ibhola lensimbi le-ejector rod aliyindilinga noma lihlutshiwe, futhi izindawo zokuthintana zegobolondo zibushelelezi futhi azinazimpawu zokugqwala.(5) Geza umshini omusha womjovo kawoyela udizili ukuze ukhiphe uwoyela ovimbela ukugqwala futhi wenze iphaseji likawoyela, umlomo wombhobho kanye negumbi likawoyela lingavimbeki.(6) Izinyathelo zomhlangano ziphambene nalezo zokuhlakaza.Lapho ufaka umhlangano we-injector, akuvunyelwe ngokuphelele ukwenza ngaphansi kwengcindezi yasentwasahlobo.(7) Qinisa ikepisi ngokwetorque eshiwo, bese ufaka induku yokukhipha, isihlalo sentwasahlobo, kanye nentwasahlobo elawula ukucindezela egobolondweni ngokushintshana, bese ugoqa isikulufu sokulungisa.Lungisa ukucindezela kusihloli se-nozzle, bese ukhiya ikepisi eliqinile ngemva kokudlula ukuhlolwa.
