Okokuqala, Noma yikuphi ukulingiswa kokugeleza komoya nge-compressor ye-turbocharger.
Njengoba sonke sazi, ama-compressor asetshenziswe kabanzi njengendlela ephumelelayo yokuthuthukisa ukusebenza nokunciphisa ukukhishwa kwezinjini zikadizili.Imithetho eqinile yokukhipha intuthu eqinile kanye nokujikeleza kabusha kwegesi ekhipha umusi osindayo kungenzeka kududule izimo zokusebenza zenjini ziye ezindaweni ezingasebenzi kahle noma ezingazinzile.Ngaphansi kwalesi simo, isivinini esiphansi kanye nezimo zokusebenza zomthwalo omkhulu wezinjini zikadizili zidinga ukuthi ama-compressor e-turbocharger anikeze umoya othuthuke kakhulu ngamazinga okugeleza aphansi, nokho, ukusebenza kwama-compressor e-turbocharger kuvame ukukhawulwa ngaphansi kwalezo zimo zokusebenza.
Ngakho-ke, ukuthuthukisa ukusebenza kahle kwe-turbocharger kanye nokwelula ububanzi bokusebenza obuzinzile kuba semqoka ezinjinini zikadizili ezikhishwa kancane ezizayo.Ukulingiswa kwe-CFD okwenziwa u-Iwakiri no-Uchida kubonise ukuthi inhlanganisela yakho kokubili ukwelashwa kwe-casing kanye nama-vane omhlahlandlela we-inlet oguquguqukayo anganikeza ububanzi obubanzi bokusebenza ngokuqhathanisa kunalokho kusetshenziswa ngakunye ngokuzimela.Ibanga lokusebenza elizinzile lishintshelwa kumazinga aphansi okugeleza komoya lapho isivinini se-compressor sincishiswa sibe ngu-80,000 rpm.Kodwa-ke, ku-80,000 rpm, ububanzi bokusebenza obuzinzile buba buncane, futhi isilinganiso sokucindezela siba siphansi;lezi zibangelwa ikakhulukazi ukugeleza kwe-tangential okuncishisiwe ekuphumeni kwe-impeller.
Okwesibili, uhlelo lokupholisa amanzi lwe-turbocharger.
Inani elandayo lemizamo lihloliwe ukuze kuthuthukiswe isistimu yokupholisa ukuze kukhushulwe okukhiphayo ngokusetshenziswa kakhulu kwevolumu esebenzayo.Izinyathelo ezibaluleke kakhulu kulokhu kuqhubekela phambili ziwushintsho ukusuka (a) komoya ukuya ekupholiseni i-hydrogen kwejeneretha, (b) ngokungaqondile ukuya ekupholiseni ukhondatha oqondile, futhi ekugcineni (c) i-hydrogen iye ekupholiseni amanzi.Amanzi okupholisa agelezela empompini esuka ethangini lamanzi ahlelwe njengethangi likanhlokweni ku-stator.Asuka empompini amanzi aqala ngokugeleza ku-cooler, filter, kanye nevalvu elawula umfutho, bese ehamba ngezindlela ezihambisanayo kuma-stator windings, ama-main bushings, kanye ne-rotor.Iphampu yamanzi, kanye nendawo yokungena namanzi, kufakwe ekhanda lokuxhuma amanzi okupholisa.Njengomphumela wamandla aphakathi nendawo, umfutho we-hydraulic usungulwa yizinsika zamanzi phakathi kwamabhokisi amanzi namakhoyili kanye nasemapayipini e-radial phakathi kwamabhokisi amanzi kanye ne-central bore.Njengoba kushiwo ngaphambili, ukucindezelwa okuhlukile kwamakholomu abandayo namanzi ashisayo ngenxa yokwenyuka kwezinga lokushisa kwamanzi kusebenza njengenhloko yokucindezela futhi kwandisa inani lamanzi agelezayo kumakhoyili ngokulingana nokwenyuka kwezinga lokushisa lamanzi namandla amaphakathi.
