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 yomfutho kawoyela womhloli 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 nesimo esimanzi, kusho ukuthi ukuvaleka kwendawo yokuvalela uphawu 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 okucacisiwe, 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 sisifushane kakhulu, kukhombisa ukuthi ukuvuleka phakathi kwevalve yenaliti nomzimba we-valve kukhulu kakhulu, noma umzimba we-valve yenaliti kanye nesiphetho esingezansi se-fuel injector body joint surface sealing 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.
