Iyo gasi rekubudaturbocharger ine zvikamu zviviri: iyo exhaust gasi turbine uye iyocompressor. Kazhinji, exhaust gasi turbine iri kurudyi uye compressor iri kuruboshwe. Ivo vane coaxial. Iyo turbine casing yakagadzirwa nekupisa-inodzivirira alloy cast iron. Mhepo inopinza yemhepo yakabatana kune cylinder exhaust pombi, uye iyo mhepo yekubuda kunze inobatanidzwa kune dizeli injini yekuburitsa chiteshi. Mhepo inopinza yemhepo ye compressor yakabatana nemhepo sefa yedhiziri injini yemhepo inlet, uye iyo mhepo yekubuda kunze inobatanidzwa kune cylinder air inlet pombi.
1. Exhaust gas turbine
Iyo exhaust gasi turbine inowanzo sanganisira aturbine housing, rin'i yemhino uye impeller inoshanda. Mhete yemuromo inoumbwa nemhete yemukati yemukati, mhete yekunze uye mashizha emumuromo. Mugero wakaumbwa nemapanga emhuno unodzinyana kubva panopinda nekupinda nawo. Iko kushanda kwemhepo kunoumbwa ne turntable uye impeller, uye mashizha ekushanda anogadziriswa pamucheto wekunze we turntable. Mhete yemuromo uye iyo iri pedyo inoshanda impeller inoumba "danho". Tubhini ine nhanho imwe chete inonzi turbine yechikamu chimwe chete. Mazhinji supercharger anoshandisa single-stage turbines.
Nheyo yekushanda kweiyo exhaust gasi turbine ndeyotevera: Kana iyoinjini yedhiziri iri kushanda, gasi rekuburitsa rinopfuura nepapombi yekuburitsa uye rinoyerera richipinda mumhete yemuromo pane imwe kumanikidza uye tembiricha. Sezvo nzvimbo yechiteshi chemhete yenozzle ichidzikira zvishoma nezvishoma, kuyerera kwegasi rekuburitsa mumhete yemuromo inowedzera (kunyangwe kudzvanywa kwayo uye tembiricha zvichiderera). Iyo yakakwirira-yekumhanyisa gasi inobuda mumhuno inopinda mugero rekuyerera mumapeller blades, uye kubuda kwemhepo kunomanikidzwa kutendeuka. Nekuda kwesimba recentrifugal, kuyerera kwemhepo kunotsikirira kwakananga kune concave pamusoro peblade uye kuedza kusiya blade, zvichikonzera mutsauko wepakati pakati pe concave uye convex nzvimbo dzeblade. Simba rinoguma remusiyano wekumanikidza rinoshanda pamablades ese rinoburitsa torque pane inotenderera shaft, zvichiita kuti impeller itenderere yakananga kune torque, uye ipapo Iyo gasi rekuburitsa rinoyerera richibuda kubva kune impeller rinoburitswa kubva pachiteshi chekuburitsa kuburikidza ne pakati pe turbine.
2. Compressor
Iyo compressor inonyanya kuumbwa neyemhepo inlet, inoshanda impeller, diffuser uye turbine dzimba. Thecompressor iri coaxial ine exhaust gasi turbine uye inofambiswa neiyo exhaust gasi turbine kutenderedza turbine inoshanda nekumhanya kukuru. Iyo turbine inoshanda ndicho chikamu chikuru checompressor. Kazhinji inoumbwa nevhiri rekutungamira mhepo yakakomberedzwa uye semi-yakavhurika yekushanda vhiri. Izvo zvikamu zviviri zvakateerana zvakaiswa pane inotenderera shaft. Mashizha akatwasuka akarongedzerwa radially pavhiri rekushanda, uye yakawedzera mhepo yekufambisa chiteshi inoumbwa pakati peshizha rega rega. Nekuda kwekutenderera kwevhiri rekushanda, mhepo yekupinda inomanikidzwa nekuda kwesimba re centrifugal uye inokandwa kumucheto wekunze kwevhiri rekushanda, zvichiita kuti kumanikidzwa, kutonhora uye kukurumidza kwemhepo kuwedzere. Kana mhepo ichiyerera nemu diffuser, iyo kinetic simba remhepo inoshandurwa kuita simba rekumanikidza nekuda kweiyo diffusion maitiro. Mukupera simbaturbine housing, simba rekinetic remhepo rinoshandurwa zvishoma nezvishoma kuva simba rekumanikidza. Nenzira iyi, iyo yekupinda mhepo density yeinjini yedhiziri inovandudzwa zvakanyanya kuburikidza necompressor.
