I-Common Rail Control Valve Set Assembly F00VC01037 & Injector Spare Part for Injector 0445110112 0445110187

Iindlela yokuhlola yokuhlanganiswa kwe-valve inaliti ye-fuel injector

(1) Ukuhlolwa kokuqina kwentamo. Sebenzisa uwoyela oxubile noma uwoyela wedizili okhanyayo ongu-20#, bese usebenzisa indlela yokucindezela ukuze wenze ebhentshini elikhethekile lokuhlola. Ngesikhathi sokuhlolwa, sebenzisa iphampu yesandla ukuze uphakamise ukucindezela ku-23-24 MPa, futhi ulinganise isikhathi sokucindezela kwehle kusuka ku-20 MPa kuya ku-18 MPa. Imiphumela yokuhlolwa ihambisana nokuthi Umkhiqizo ojwayelekile kufanele uqhathaniswe nobubanzi obudingekayo.

(2) Ukuhlolwa kokuvala isihlalo. Sebenzisa u-20# uwoyela we-diesel okhanyayo ebhentshini lokuhlola eline-accumulator yokucindezela, qala ngokulungisa ukucindezela komjovo kaphethiloli kungcindezi eshiwo engu-12.5 MPa, bese ukhuphula umfutho kawoyela ngo-0.1 MPa njalo ngamasekhondi ama-3 ukuya kwangu-5 ngokulinganayo kuze kube ekuqaleni komjovo. Amafutha, bheka ikhwalithi yokuvala uphawu, ukuvuza kukawoyela okuncane kuvunyelwe, futhi ububanzi bokuvuza kwamafutha abukho ngaphezu kuka-5 mm (isihlalo nobuso akugayani) noma 3 mm ububanzi (isihlalo kanye ubuso bugayane). Kodwa hhayi esimweni esiyindilinga esiyindilinga.

(3) Ukuhlolwa kwesifutho. Sebenzisa u-20# uwoyela we-diesel okhanyayo ebhentshini lokuhlola, lungisa umfutho womjovo kaphethiloli ube ngu-12.5 MPa, bese wenza ukuhlolwa kwesifutho ngenani lomjovo izikhathi ezingama-40-80/imiz. 

Ikhwalithi yesifutho kufanele ihlangabezane nezidingo ezilandelayo:

①Uphethiloli ojovwe kufanele ube yi-athomu, futhi akumele kube nezinhlayiya zikawoyela ochaphazayo kanye nokugxilisana kwendawo okungalingani okungabonwa ngeso lenyama.

②Ukuqala nokuphela kokufutha kufanele kube sobala, futhi umsindo kufanele ube nomsindo.

③Ngaphambi kokuqala kokufafaza nangemva kokuphela kokufafaza, ukuvuza kwamafutha akuvunyelwe emgodini we-spray, kodwa umswakama uvunyelwe.

(4) Hlola i-engeli yesifutho. Hlola ngeso lenyama, qhathanisa i-engeli yesifutho ngaphansi komfutho womjovo kaphethiloli osetshenziswa enjinini kadizili nesampula, futhi ukuchezuka phakathi komugqa omaphakathi we-engeli yesifutho yesijovo sikaphethiloli kanye nomugqa omaphakathi womjovo kaphethiloli awukukhulu. ngo-4°30'. I-angle ye-spray cone ibonwa ngaphakathi kwe-100 mm.

(5) Ukuhlolwa kokushelela. Hlanza ngokucophelela futhi ugcobe izingxenye ngamafutha edizili ahluzwe kahle. Lapho i-valve yenaliti iku-45° endaweni evundlile, donsa ivalve yenaliti emzimbeni inaliti nge-1/3 yobude bayo. Yiphendule kunoma yikuphi ukuma futhi uyiyeke. Isisindo ngokwaso sishelela ngokukhululeka ngaphandle kwesithiyo.
