Umjovo ka-Diesel Fuel Injector 0445110668 Bosch for Cummins/Foton

Hlola futhi ulungise isijojo sikaphethiloli

Umjovo wamafutha kufanele uhlolwe kumhloli okhethekile. I-drip ye-nozzle kufanele ihlolwe lapho kulungiswa i-injector. Ingcindezi yomjovo womjovo ilungiswa ngokujwayelekile, futhi ukuhlolwa kwekhwalithi ye-atomization kuyafaneleka. Lungisa iphampu yengcindezi kawoyela yesihloli ibe ngu-1-2 MPa ngaphansi kokucindezela komjovo onqunyiwe, futhi uyigcine ngaphezu kwama-10s. Ngalesi sikhathi i-nozzle kawoyela kufanele ingabi nawo amafutha. Uma kukhona ukuvuza kukawoyela kanye nesenzakalo esimanzi, kusho ukuthi ukuvaleka kwendawo yokuvala okuqinile kubi futhi kudinga ukubhangqwa nokugaya noma ukushintshwa. Lapho ulungisa i-injector, indlela yokuhlola inani lokubuya kwamafutha iwukuba kuqala ulungise ingcindezi yomjovo ibe ngu-8 ~ 10 MPa ephakeme kunokucindezela okushiwo, bese unyakazisa isibambo sikawoyela wepompo, ukuze ukucindezela komhloli kukhuphuke. kuya ku-4 ~ 5 MPa ngaphansi kwevelu yokucindezela engenhla. Ngalesi sikhathi, bheka isikhathi esidingekayo lapho ukucindezela kwegeji yokucindezela kwehlela ku-2MPa. Uma ubude bokwehla buphakathi kwamasekhondi angu-10 no-20, kufanelekile. Uma isikhathi sisifishane kakhulu, kukhombisa ukuthi ukuvuleka phakathi kwe-valve yenaliti kanye nomzimba we-valve kukhulu kakhulu, noma umzimba we-valve yenaliti kanye nomkhawulo ongezansi wokuvalelwa kwendawo okuhlangene komjovo kaphethiloli akuqinile, kufanele kushintshwe injini yedizili. ukuthembeka kwe-valve, ukuqina kuthinta ngqo impilo yenjini ye-diesel. Ukulimala kokuqina komoya kuzophazamisa ukusebenza kwenjini kadizili. Ukulahlekelwa okubangelwa ukuphuka kwe-valve kungaphezulu kakhulu kwenani le-valve ngokwayo, futhi umphumela mubi kakhulu.
