Auto Parts Diesel fuel injection Nozzle DNOPDN112 fuel nozzle DN0PDN112 for injini yedizili

Inkqubo yokudilizwa kweperi yomlomo wesitofu

1.1 Ukucoca

Gxila umbhobho wesitofu ukuze ulungiswe kwi-oyile ye-diesel ekhanyayo iiyure ezininzi, emva koko uyikhuphe, kwaye uhlambe umphezulu ngebrashi yocingo olucolekileyo lobhedu ukususa umhlwa, i-oyile kunye neediphozithi zekhabhoni.

1.2 Sebenzisa isixhobo esikhethekileyo ukucima umngxuma ophezulu we-injector

Sebenzisa ucingo lwentsimbi olunobubanzi obuyi-1.5mm ukucola umphetho kwaye udilize zonke iidiphozithi zekhabhoni kunye nobumdaka obungaphakathi kumjelo wokungena kwe-oyile womzimba wombhobho wesitofu.

Lola isixhobo sokuphinda sisebenze ngendlela efanayo kumngxuma we-oyile kumzimba womlomo wesitofu, kwaye ususe zonke iidiphozithi zekhabhoni kunye nobumdaka obukwigumbi lokugcina i-oyile.

Ukuba umlomo wesitofu kunye nomzimba we-injector ziyanamathelana, sebenzisa isixhobo esikhethekileyo sokususa ukususa umbhobho wesitofu obambekayo. Musa ukusebenzisa iipliyisi ukukhupha umbhobho wesitofu, okanye ubambe umphini wesitofu kwivise ukuze uyibhutyuze, ukuthintela ukugotywa kweminye imilomo yesitofu kwaye yophuke isiphatho sombhobho wesitofu kunye nokuchithwa. Kumbhobho wokutofela okungekho lula ukuwuqhawula ngezixhobo ezikhethekileyo, unokufakwa kwi-oyile ye-injini kwaye ufudunyezwe ukuya kuma-150 ° C, kwaye emva koko ukhutshwe kwaye uhlakazwe ngelixa kuseshushu.

1.3 Ukuhlolwa

Emva kokucoca, khangela zonke iinxalenye ze-injector ye-fuel, ngakumbi i-nozzle ye-injector pair, ukugqiba ukuba utshintshe okanye ulungise. Isikhokelo se-cylindrical sombhobho we-injector mnyama, kwaye ngelo xesha, i-nozzle ye-injector ifakwe kwi-nozzle ye-injector kwaye ivakalelwa kukuba ikhululekile, ebonisa ukuba indawo yesikhokelo ine-gap enkulu. Xa kusetyenziswa, kufuneka kubekho ukubuya kweoli eninzi, kwaye uxinzelelo lweoyile alukwazi ukulungiswa phezulu. Ukuzama ukwandisa uxinzelelo lwe-oyile kunokubangela ukuba uxinzelelo olulawulayo lwentwasahlobo lungaphumeleli, kwaye ioli ayiyi kutshizwa.

Umgca wevalve womlomo wesitofu udlala indima yokulawula umthamo wenaliti yamafutha, ukugcina uxinzelelo oluthile lwenaliti kunye nokuqinisekisa ukucolwa kakuhle kwenaliti yamafutha. Ukuba kukho imiqondiso yomonakalo, ayivalwanga ngexesha lokusetyenziswa, kwaye i-pulverization ye-injection ye-fuel ihluphekile okanye ayinakho i-atomized. Kwangaxeshanye, kukho ukuthontsiza kumphezulu womngxuma we-nozzle we-injector nozzle.

Kukho iimpawu zokungalingani kunye nomonakalo kwindiza edibeneyo yokuphela okukhulu kwe-nozzle ye-injector, ebonisa ukuba ayisetyenziswanga kakuhle. Ukuba isiphene sikwiringi yangaphandle, i-fuel iya kuvuza ngexesha lokusetyenziswa; ukuba isiphene sikwiringi yangaphakathi, i-fuel iya kuvuza kwi-oil return hole.

Intsebenziswano phakathi komngxuma wokutofa womzimba wombhobho wesitofu kunye nentloko encinci yombhobho wesitofu akufunekanga ikhululeke kakhulu okanye iqine kakhulu. Ukuba ikhululekile kakhulu, umgangatho we-pulverization uya kuncipha, i-pulverization iya kuba yincinci kwaye iincinci zeoli ziya kuba zikhulu, kwaye isandi asiyi kuba buhlungu. Ukuba iqine kakhulu, inaliti yamafutha iya kwenza umgca, inaliti yamafutha iya kuthi cwaka, kwaye ukuba isitofu samafutha sihlala ixesha elide, i-pulverization iya kwenzeka ngokulula.
