I-China Yenze uMgangatho oPhakamileyo weDizili kaLoliwe /Injector yeFuel NozzleDLLA144P191 YE-CUMMINS ENGINE

Uhlalutyo lwesizathu sokuba umlomo wesitofu ubambeke kwii-injector.(Icandelo 1)

1 Ukuqinisekiswa kwezinto zokuvavanya

Ngokuhlalutywa kwezizathu ezinokubakho zokuncamathelwa kokudibanisa inaliti yomlomo, kwagqitywa ekubeni kwenziwe uthotho lohlolo nohlalutyo kwindibano yomlomo yomlomo ephosakeleyo.Izinto ezithile zokuhlola zezi zilandelayo:

1) Khangela ukucaca okuhambelanayo kokudibanisa kunye nokufaneleka kwendawo yokuhlala yevalve yenaliti;

2) Phinda ulinganise ukujikeleza, i-cylindricity, i-roughness, kunye nobunzima bomhlaba we-valve yenaliti emva kokucoca (ukususa i-rust surface, njl.);

3) Ukucoca (ukususa umhlwa ongaphezulu, njl.

4) Gcoba ivalve yenaliti kunye nombhobho, kwaye wenze uhlolo lombala kwindawo yokukhwelana kwivalve yenaliti kunye nombhobho;

5) Ngenisa ivalve yenaliti kunye nombhobho wokuhlola i-metallographic, umlinganiselo wobumdaka.

Iziphumo zovavanyo ezi-2
2.1 Iziphumo zomlinganiselo wedayamitha yangaphandle yevalve yenaliti yomgangatho kunye nedayamitha yangaphakathi yendawo yokufaka umlomo wombhobho iboniswe kwiThebhile 1. Phakathi kwazo, iindawo ezilinganayo ezinenombolo yesitampu i-HHM azifakelwanga kwaye ziyasebenza.Ukusuka kwidatha yokulinganisa, kunokubonwa ukuba izikhewu ezifanelekileyo zeeseti ezimbini zokudibanisa zikhulu kunexabiso loyilo, ukujikeleza komngxuma wangaphakathi wevalve yenaliti kunye nombhobho onenombolo yesitampu HD zonke ziyahlangabezana neemfuno zoyilo, kunye nokungqukuva komngxuma ongaphakathi wevalve yenaliti kunye nombhobho onenombolo yesitampu i-HHM idlula uyilo Funa.Indawo engaphezulu yevalve yenaliti enenombolo yesitampu sentsimbi HD inobuzaza, kwaye indawo efanelekileyo ayinakuhlolwa.Imeko ethile iboniswe kuMfanekiso2.

Umphezulu ofanelekileyo we-valve yenaliti kunye nenombolo yesitampu yensimbi i-HHM ibanzi, kunye ne-bandwidth malunga ne-2mm, njengoko kuboniswe kuMzobo 3 (indawo yokukhwelana iya kuba mnyama emva kokuba isibini siphantsi kancinci, ngoko unokwazi ukujonga imeko efanelekileyo).Ukongeza, i-cone angle ekupheleni kwevalve yenaliti iyalinganiswa, kwaye ukuyila kufuna i-cone angle ye-91 ° ± 5 '.I-angle yenaliti yentsimbi yokutywinwa kwentsimbi eqala i-HHM yi-91 ° 1′, kunye ne-angle yevalve yenaliti yenombolo yesitampu sentsimbi eqala i-HD yi-91 ° 2′, zombini ezihlangabezana neemfuno zemizobo.
