I-Cummins Engine Ingxenye ye-Piston Cooling Nozzle 4095461 Yenjini ye-Cummins QSK23

Umgomo wokusebenza we-piston cooling nozzle

Uma i-piston ingathathi izinyathelo ezikhethekile, ukushisa kungadluliselwa kuphela kwinkungu yamafutha ku-crankcase ngokusebenzisa indawo engaphakathi ye-piston.Uma kudingekile ukuqinisa ukupholisa kwepiston, ingxenye yokugeleza kwamafutha amafutha okugcoba ajikelezayo enjini yemoto ihlanganiswe futhi ivunyelwe ukugeleza ku-piston.Ukuze wenze umphumela wokupholisa kanye nezindleko zokukhiqiza zihlangabezane nezidingo, kuningi okungenzeka.Isixazululo esilula kunazo zonke: uma induku yokuxhuma inembobo ye-longitudinal, imbobo yamafutha isethwe emgodini omkhulu noma omncane wenduku yokuxhuma, futhi imbobo yamafutha kufanele ihambisane nokuma kohlangothi lwangaphakathi lwepiston.Imbobo kawoyela inikeza ijethi kawoyela enyakazayo phakathi kwe-engeli yokushwibeka yenduku yokuxhuma.Ngenxa yokucatshangelwa kokugcotshwa kwebhering yenduku yokuxhuma namandla angasebenzi asebenza kuwoyela, kunenani elilinganiselwe kuphela lamafutha okupholisa ipiston.Kuthembeke kakhulu futhi kusebenza kangcono ukujova uwoyela ku-piston kusuka ku-nozzle egxilwe emzimbeni.

Ngesikhathi sokusebenza kwemoto, ukuze kuqinisekiswe ukuthi inhloko ye-piston yenjini yemoto ayishisi ngokweqile, ikhanda le-piston lidinga ukupholiswa.Umgomo wokupholisa uwukusetha iphaseji lamafutha okupholisa ekhanda lepiston, bese upholisa ngepiston efakwe ekhanda le-cylinder.Umbhobho ufutha uwoyela opholisayo ephaseji likawoyela opholisayo ukuze unciphise izinga lokushisa lekhanda lepiston.Ekwakhiweni kwenjini yendabuko, i-piston ivamise ukufakwa umlomo wokupholisa, futhi isiqondiso sokujova uphethiloli silungisiwe.Enjinini enamasilinda amaningi, kubakaki abaningi bokupholisa umlomo okupholisa bayadingeka, futhi imibhobho yokupholisa ye-piston ifakwa kakhulu kubhulokhi yesilinda.Isakhiwo sokufakwa kwegumbi kanye nepiston ngokuvamile kudinga amathuluzi akhethekile ukufaka umlomo wombhobho wokupholisa ipiston ebhulokhini lenjini.Inqubo yokufaka iyinkimbinkimbi futhi izindleko zokusebenzisa ziphezulu.

Ngakho-ke, kuyadingeka ukuthuthukisa i-nozzle ekhona ye-piston yokupholisa injini, engakwazi ukupholisa i-piston ngesikhathi sokusebenza kwenjini, isindise inani lezingxenye ezisetshenzisiwe, futhi yonge izindleko.
