Amanqaku okufunda nge-turbocharger

Inkqubo yokuthwala i-simulator ye-rotor yayisetyenziswa ngelixa ibekwe kwiindlela ezahlukeneyo zokuqhelaniswa.Uvavanyo olulandelayo lwagqitywa ukubonisa amandla eebheringi zefoil thrust encinci ngokunjalo.Unxulumano oluhle phakathi komlinganiselo kunye nohlalutyo luyabonwa.Amaxesha amafutshane kakhulu okukhawulezisa i-rotor ukusuka ekuphumleni ukuya kwisantya esiphezulu nawo alinganiswa.I-parallel test simulator isetyenziselwe ukuqokelela ngaphezulu kwe-1000 ye-start-stop cycles ukubonisa ubomi bokuthwala kunye ne-coating.Ngokusekelwe kolu vavanyo oluyimpumelelo, kulindeleke ukuba injongo yokuphuhlisa i-oil free turbocharger kunye neenjini ze-turbojet ezincinci ezisebenza ngesantya esiphezulu kunye nobomi obude ziya kufezekiswa.

Iimfuno zokusebenza okuphezulu, iibheringi zexesha elide zolu didi olutsha lomatshini zinzima.Iibheringi eziqhelekileyo zokuqengqeleka zicelwa umngeni ngamandla sisantya kunye nomthamo womthwalo ofunekayo.Ukongeza, ngaphandle kokuba inkqubo yolwelo ingasetyenziswa njenge-lubricant, inkqubo yokuthambisa yangaphandle iya kuba phantse ngokuqinisekileyo.

Ukuphelisa iibheringi ezigcotyiweyo zeoyile kunye nenkqubo yonikezelo ehambelana nayo iya kwenza lula inkqubo ye-rotor, ukunciphisa ubunzima benkqubo, kunye nokuphucula ukusebenza kodwa kuya kwandisa amaqondo obushushu angaphakathi, okuya kuthi ekugqibeleni kufune iibheringi ezikwaziyo ukusebenza kumaqondo obushushu asondela kwi-650 ° C kunye nesantya esiphezulu kwaye imithwalo.Ngaphandle kokusinda kumaqondo obushushu agqithisileyo kunye nezantya, iibheringi ezingenawo i-oyile nazo ziyakudinga ukulungiselela ukothuka kunye neemeko zokungcangcazela ezifunyanwa kwizicelo eziphathwayo.

Ubunokwenzeka bokusebenzisa iibheringi ezithobelayo kwiinjini ze-turbojet ezincinci zibonakaliswe phantsi koluhlu olubanzi lobushushu, ukothuka, umthwalo, kunye neemeko zesantya.Uvavanyo ukuya kwi-150,000 rpm, kwiqondo lokushisa elingaphezulu kwe-260 ° C, phantsi komthwalo wokuthuthumela kwi-90g kunye ne-rotor orientations kuquka i-90 deg pitch kunye ne-roll, zonke zagqitywa ngempumelelo.Ngaphantsi kwazo zonke iimeko ezivavanyiweyo, i-foil ethwele i-rotor exhaswayo yahlala izinzile, i-vibrations yayiphantsi, kwaye amaqondo okushisa athwele azinzile.Ngokubanzi, le nkqubo ibonelele ngemvelaphi eyimfuneko ukuphuhlisa i-turbojet engenawo ioyile ngokupheleleyo okanye i-injini ye-turbofan ephezulu.
