Okokuqala, Nakuphi na ukulinganisa ukuhamba komoya ngecompressor ye-turbocharger.
Njengoko sonke sisazi, iicompressors zisetyenziswe ngokubanzi njengendlela efanelekileyo yokuphucula ukusebenza kunye nokunciphisa ukukhutshwa kweenjini zedizili. Imithetho engqongqo yokukhupha igesi ephumayo kunye nokujikeleziswa kwerhasi eninzi kunokwenzeka ukuba kutyhalele iimeko zokusebenza kwe-injini ukuya kwimimandla engasebenzi kakuhle okanye engazinzanga. Phantsi kwale meko, isantya esiphantsi kunye neemeko zokusebenza eziphezulu zomthwalo weenjini zedizili zifuna ukuba iicompressors ze-turbocharger zibonelele ngesantya esiphezulu somoya kumazinga okuhamba okuphantsi, nangona kunjalo, ukusebenza kweecompressor ze-turbocharger kuqhelekile kuthintelwa phantsi kwezo meko zokusebenza.
Ke ngoko, ukuphucula ukusebenza kakuhle kwe-turbocharger kunye nokwandisa uluhlu oluzinzileyo lokusebenza kuya kuba yimfuneko kwikamva eliphantsi leenjini zedizili ezikhutshwayo. Ukulinganisa kwe-CFD okwenziwa ngu-Iwakiri no-Uchida kubonise ukuba indibaniselwano yonyango lwe-casing kunye ne-variable inlet guide vanes inokubonelela ngoluhlu olubanzi lokusebenza ngokuthelekisa kunokusebenzisa nganye ngokuzimeleyo. Uluhlu oluzinzileyo olusebenzayo lutshintshelwe kumazinga aphantsi okuhamba komoya xa isantya secompressor sincitshiswa ukuya kwi-80,000 rpm. Nangona kunjalo, kwi-80,000 rpm, uluhlu oluzinzile lokusebenza luba luncinci, kwaye umlinganiselo woxinzelelo uba ngaphantsi; ezi zibangelwa ikakhulu kukuhamba okucuthiweyo kwe-tangential kwi-impeller exit.
Okwesibini, inkqubo yokupholisa amanzi ye-turbocharger.
Inani elandayo lemizamo iye yavavanywa ukuphucula inkqubo yokupholisa ukuze kunyuswe imveliso ngokusetyenziswa ngamandla komthamo osebenzayo. Awona manyathelo abalulekileyo kolu kuqhubela phambili lutshintsho ukusuka (a) emoyeni ukuya kwi-hydrogen epholileyo yejenereyitha, (b) ngokungathanga ngqo ukuya ngqo kumqhubi wokupholisa, kwaye ekugqibeleni (c) i-hydrogen ukuya ekupholiseni kwamanzi. Amanzi okupholisa aya kumpompoza esuka kwitanki yamanzi ehlelwe njengetanki yentloko kwi-stator. Ukusuka kumpompo wamanzi kuqala uqukuqela kwindawo epholileyo, isihluzi, kunye nevalve elawula uxinzelelo, emva koko uhambe ngeendlela ezinxuseneyo kwi-stator windings, i-main bushings, kunye ne-rotor. Impompo yamanzi, kunye ne-inlet kunye ne-outlet yamanzi, zibandakanyiwe kwintloko yokudibanisa amanzi okupholisa. Njengomphumo wamandla wabo we-centrifugal, uxinzelelo lwe-hydraulic lusekwe yiintsika zamanzi phakathi kweebhokisi zamanzi kunye neekhoyili kunye nakwimibhobho ye-radial phakathi kweebhokisi zamanzi kunye ne-central bore. Njengoko kukhankanyiwe ngaphambili, ukunyanzeliswa koxinzelelo lweentsika zamanzi abandayo kunye namanzi ashushu ngenxa yokunyuka kweqondo lokushisa kwamanzi lisebenza njengentloko yoxinzelelo kwaye kwandisa ubuninzi bamanzi ahamba ngee-coil ngokulingana nokunyuka kweqondo lokushisa kwamanzi kunye namandla e-centrifugal.
