Ukuthembeka kweRotor Phantsi kobushushu obuphezulu kunye nokusebenza ixesha elide rhoqo kuba yinto entsha ekunyibilikeni kweAluminiyam

Njengoko imigca yokucubungula i-aluminium yehlabathi iqhubeka isiya phambiliamaqondo obushushu aphezulu, imveliso eqhubekayo ixesha elide, kunye nokuvalwa okuncinci kokugcinwaUkuqinisekisa ukuba iirotor ezisusa igesi kwigrafiti zihlala zizinzile kwaye zithembekile phantsi kweemeko ezinzima kuye kwaba yinto ephambili kwizityalo ezinyibilikisa i-aluminium.

Kutshanje, umboneleli wezisombululo zobunjineli bomphezulu kunye nokugquma kwishishini uqalise isisombululo sokuthembeka ngokukodwa kwiirotha zokususa igesi zegrafiti ezisebenza kwiimeko zobushushu obuphezulu, ezihlala ixesha elide. Esi sisombululo sele sisetyenzisiwe kwizityalo ezininzi ze-aluminium kwaye sitsala ingqalelo enkulu.

1. Ubushushu obuphezulu + Imijikelo emide

Ngenxa yokuphuculwa kweemveliso ze-aluminium alloy kunye nokunyuka kwamanqanaba okusebenza ngokuzenzekelayo, ixesha elichithwa kanye leentambo ezininzi zokunyibilika kunye nokufaka isinyithi liye landa kakhulu. Ngoku kuqhelekile ukuba iirotor zifakwe kwi-aluminium enyibilikisiweyo kwi700–750 °C nangaphezuluixesha elide ngelixa lijikeleza rhoqo.

Phantsi kwezi meko, iirotha zegrafiti zesiqhelo zinotyekelo loku:

• Ukukhawuleziswa kwe-oxidation yobushushu obuphezulu, okubangela ukurhawuzelela nokuqhekeka komphezulu ngokukhawuleza;

• Ukuqhekeka okanye ukwaphuka ngenxa yokuxinana kobushushu kunye noxinzelelo loomatshini;

• Ukuxobuka nokuqhekeka kwengubo okubangelwa kukungangqinelani kobushushu phakathi kwengubo kunye negrafiti;

• Ukwehla okubonakalayo kokusebenza kakuhle kokukhupha igesi ngokuhamba kwexesha, nto leyo ekhokelela kwiziphene ezingakumbi zokubola.

2.Ukusuka kwizinto ezibonakalayo ukuya ekugubungeleni

Kwiimeko zokusebenza ezisebenza ixesha elide nezishushu kakhulu, isisombululo esitshahayimalunga "nokongeza umaleko wokugquma" kwiirotha ezikhoyo. Endaweni yoko, iphucula yonke inkqubo—ukusuka ekukhetheni i-graphite substrate kunye nesakhiwo serotha ukuya kwinkqubo yokugquma kunye nolawulo lwenkqubo:

• Ukukhetha okucociweyo kwe-grafiti substrate
  Ngokulawula uxinano lwegrafiti, ulwakhiwo lwemingxuma, kunye neempawu ze-anisotropic, isisombululo sinciphisa uxinaniso lwangaphakathi loxinzelelo kunye neendlela ze-oxidation, sibeka isiseko esiqinileyo sokusebenza ixesha elide kubushushu obuphezulu.

• Ulwakhiwo lweRotor oluyilelwe ukuthembeka
  I-impeller, imijelo yokuhamba, kunye namacandelo otshintsho alungiselelwe ngokwesakhiwo ukususa iikona ezibukhali kunye namacandelo abuthathaka kwiindawo ezixinezelekileyo, nto leyo ephucula ukumelana noxinzelelo lobushushu.

• Iingubo zobushushu obuphezulu ezinefilosofi "ehambelanayo"
  Kusetyenziswa iinkqubo zokugquma ezidityanisiweyo ezinee-coefficients zokwandisa ubushushu ezikufutshane ne-graphite. Ezi aziboneleli nje kuphela ngokumelana nokugqwala okugqwesileyo, kodwa zikwanciphisa ukuqhekeka nokuqhekeka okubangelwa kukungalingani kobushushu.

• Ulawulo lwenkqubo lugxile kumaleko "axineneyo nafanayo"
  Ngokusebenzisa iinkqubo zokugquma ezisebenzisa amanyathelo amaninzi kunye neenkqubo zokugquma ezilawulwayo, isisombululo siphucula uxinano lwengubo kunye nokunamathela, sithintela ukuvezwa kwangoko kwe-graphite substrate phantsi kokuhamba kwexesha elide kunye nokukhukuliseka.

3. Iziphumo zeSithili

Kwizityalo ezinyibilikisa i-aluminium ezisebenzise ezi mveliso zintshaiirotor zokususa igesi ngegrafayithi, iziphumo phantsi kweemeko zenkqubo ezifanayo ziquka:

• Ubomi benkonzo obongezelelekileyo kakhulu kwi-rotor nganye, kunye nokutshintshwa okuncinci kwe-rotor;

• Ukusebenza okuzinzileyo ngakumbi kokususa igesi, kunye nokunqongophala okuncinci kunye nezikhalazo zokubandakanywa kwiiphulo ezinde zokudubula;

• Ukunciphisa ixesha lokungasebenzi lokulungisa, okukhokelela ekubeni ixesha lokusebenza kunye nemveliso ephezulu kumgca wonke;

• Ukuncipha okuphawulekayo kweziganeko zequbuliso ezibangelwa kukwaphuka kwerotor okanye ukususwa kwengubo.

Kuyabonakala ukuba nabani na onokuqala asombulule imingeni yokuthembeka kweerotha zokususa igesi zegrafiti phantsi kokusebenza okushushu kakhulu, ixesha elide uya kuqalisa kakuhle kumjikelo olandelayo wokuphuculwa kwenkqubo yokunyibilikisa i-aluminium. Ngokuphathelele umxholo othi "ukujongana neenkqubo ezinzima," ukusasazwa kobuchwephesha kunye nemveliso kuye kwaba yindawo entsha yokulwa apho ishishini le-aluminium kunye nababoneleli berotha beqinisa imizamo yabo.
