Isitofu se-Diesel Injector ye-Fuel 0445120150 Bosch ye-Weichai 6.2 Injini

I-Cavitation Ngaphakathi koxinzelelo oluphezulu lweMibhobho yesitofu seFuel eNgaphandle(ICANDELO 6)

Ngalo lonke ixesha lokutofa, imingxunya eludongeni ibonakala kwicala leentsiba ezikude kakhulu nomzimba wesitofu, apho ikona yokungena ibukhali. Imingxunya inabela phantse yonke indlela eya kwi-orifice yokuphuma, apho ikhupha amafu mhlawumbi aphila ngaphandle komzimba wokutofa. Akukho bungqina bentambo ye-cavitation kwi-sac volume ingabonwa, nangona i-vorticity ibonakala kwiividiyo ezikhawulezayo.

Ngaphandle komtya we-cavitation, i-transient cavitation cloud shedding ibonakala kwicala le-orifice ejongene nodonga olumileyo kwi-orifice kunye ne-angle yokuthambekela enkulu ukusuka kwi-axis esembindini ye-injector. Umngxunya omileyo wodonga kule orifice ukhona ecaleni kwe-orifice inlet inlet yonke, ngoko ke mhlawumbi la mafu alahlwa ukusuka kumngxuma wodonga, apho aya kuba sisiphumo se-geometric cavitation.

Umahluko obalulekileyo phakathi kwesi sitofu kunye nezinye ii-injection kwizifundo ezidlulileyo kukungabikho kwenaliti. I-shaft yokumisa emileyo ayinamgongxo, kwaye ke eyona vortex inkulu kumthamo wengxowa ikhona ngenene kweyona ndawo ikude ye-axial kumthamo wengxowa, apho umqukuqelo ujikela umva umva ukuya kungena kumbhobho ophuma emlonyeni. Umtya we-Cavitation phakathi kwee-orifices awuzange ubonwe kwezi zifundo.

Xa umlomo wombhobho ungaphumeleli, uxinzelelo lwevolumu yesac luyakwehla ngesiquphe, kwaye oku kubonwe kumlinganiselo woxinzelelo lwevolumu yesac. Uxinzelelo lokugqibela olunokumelana noyilo lokugqibela lwaluyi-600 bar. Ngelixa olu xinzelelo lwenaliti lungekho phezulu njengezinye iiphononongo ezidlulileyo, i-nozzle orifices yolu yilo mikhulu ngokungaqhelekanga.

4 Izigqibo

Umlomo wesitofu esisebenza ngokubonakalayo obonakalayo wayilwa kusetyenziswa indlela evavanya ngononophelo ngakumbi ukusilela komlomo womlomo ngenxa yemathiriyeli esetyenzisiweyo kulwakhiwo lwawo.
