Okunye ukumodela nokuhlaziywa kokuhlola embonini ye-turbocharger

Imodeli yenjini enohlangothi olulodwa

Kuthuthukiswe imodeli yohlangothi olulodwa ukuze ibikezele ukusebenza kwe-radial-inflow turbine ehanjiswe ezimeni zokugeleza ezingazinzile. Ngokuhlukile kwezinye izindlela zangaphambilini, i-turbine ilingiswe ngokuhlukanisa imiphumela ye-casing ne-rotor ekugelezeni okungaqinile nangokumodela okufakiwe kwama-rotor amaningi kusuka ku-volute.

Kuyindlela elula nesebenzayo yokumela ivolumu ye-turbine ngenethiwekhi yamapayipi anohlangothi olulodwa, ukuze uthwebule umphumela wokugcinwa kwenqwaba ngenxa yevolumu yesistimu, kanye nokuhluka okuyisiyingi kwezimo eziguqukayo zoketshezi ku-volute, enesibopho. ngokungeniswa okuguquguqukayo kwesisindo ku-rotor ngokusebenzisa amaphaseji e-blade. Indlela eyakhiwe iyachazwa, futhi ukunemba kwemodeli yohlangothi olulodwa kuboniswa ngokuqhathanisa imiphumela ebikezelwe nedatha elinganisiwe, efinyelelwe kumshini wokuhlola onikezelwe ophenyweni lwama-turbocharger ezimoto.

I-turbocharging enezigaba ezimbili

Inzuzo enkulu ye-turbocharging yezigaba ezimbili ivela eqinisweni lokuthi imishini emibili yesilinganiso sokucindezela okuvamile nokusebenza kahle ingasetshenziswa. Ingcindezi ephezulu iyonke kanye nezilinganiso zokunwetshwa zingathuthukiswa kusetshenziswa ama-turbocharger ajwayelekile. Okubi okuyinhloko ukukhuphuka kwezindleko ze-turbocharger eyengeziwe kanye ne-intercooler nokuphindaphinda.

Ukwengeza, i-Interstage intercooling iyinkinga, kodwa ukwehla kwezinga lokushisa endaweni yokungena kwe-HP compressor kunenzuzo eyengeziwe yokunciphisa umsebenzi we-HP compressor wesilinganiso sokucindezela esinikeziwe, njengoba lokhu kuwumsebenzi wokushisa kwe-compressor inlet. Lokhu kwandisa ukusebenza kahle phezu kwakho konke kwesistimu ye-turbocharging. Ama-turbines nawo ayazuza esilinganisweni esiphansi sokunwetshwa ngesiteji ngasinye. Ezilinganisweni eziphansi zokunwetshwa, ama-turbines angasebenza kahle kakhulu kunokuba kungaba njalo ngohlelo lwesiteji esisodwa. Amasistimu ezigaba ezimbili, ngokusebenzisa ukusebenza kahle kwesistimu ye-turbocharger, ahlinzeka ngomfutho ophakeme wokunyusa, ukusetshenziswa komoya okukhulu kakhulu ngakho-ke i-valve yokukhipha umoya ephansi kanye nezinga lokushisa lokungena kwe-turbine.
