Phakathi kweendawo zokusebenza ze-hydrogen i-fuel cell stacks kunye ne-compressors yomoya, i-rotor iyisitshixo kumthombo wamandla, kwaye izikhombisi zayo ezahlukeneyo zihambelana ngqo nokusebenza kakuhle kunye nokuzinza komatshini ngexesha lokusebenza.
1. Iimfuno zeRotor
Iimfuno zesantya
Isantya kufuneka sibe ≥100,000RPM. Isantya esiphezulu kukuhlangabezana nokuhamba kwerhasi kunye neemfuno zoxinzelelo lwezitaki zeeseli ze-hydrogen kunye neecompressor zomoya ngexesha lokusebenza. Kwiiseli ze-hydrogen fuel, i-compressor yomoya kufuneka icinezele ngokukhawuleza isixa esikhulu somoya kwaye siyihambise kwi-cathode yesitaki. I-rotor enesantya esiphezulu inokunyanzela umoya ukuba ungene kwindawo yokusabela kunye nokuhamba okwaneleyo kunye noxinzelelo lokuqinisekisa ukusabela ngokufanelekileyo kweseli yamafutha. Isantya esiphezulu esinjalo sinemigangatho engqongqo yamandla ezinto eziphathekayo, inkqubo yokuvelisa kunye nokulinganisela okuguquguqukayo kwe-rotor, kuba xa ijikeleza ngesantya esiphezulu, i-rotor kufuneka imelane namandla amakhulu e-centrifugal, kwaye nakuphi na ukungalingani okuncinci kunokubangela ukungcangcazela okukhulu okanye umonakalo wecandelo.
Iimfuno zolungelelwaniso olunamandla
Ibhalansi eguqukayo idinga ukufikelela kwinqanaba le-G2.5. Ngethuba lokujikeleza kwesantya esiphezulu, ukusabalalisa ubuninzi be-rotor kufuneka kube yinto efanayo njengoko kunokwenzeka. Ukuba ibhalansi eguquguqukayo ayilungile, i-rotor iya kuvelisa i-tilted centrifugal force, engayi kubangela kuphela ukungcangcazela kunye nengxolo yezixhobo, kodwa ikhulise ukunxiba kwamacandelo afana neebheringi, kunye nokunciphisa ubomi benkonzo yezixhobo. Ukulinganisa okunamandla kwinqanaba le-G2.5 kuthetha ukuba ukungalingani kwe-rotor kuya kulawulwa ngaphakathi kwinqanaba eliphantsi kakhulu ukuqinisekisa ukuzinza kwe-rotor ngexesha lokujikeleza.
Iimfuno zokuhambelana kwentsimi yemagneti
Imfuno yemagnethi ehambelanayo ngaphakathi kwe-1% ubukhulu becala i-rotors enemagnethi. Kwinkqubo yemoto enxulumene nezitaki zeeseli ze-hydrogen, ukufana kunye nokuzinza kwendawo yamagnetic kunefuthe eliqinisekileyo ekusebenzeni kwemoto. Ukuchaneka kwemagnethi ngokuchanekileyo kunokuqinisekisa ukuguda kwetorque yemoto kunye nokunciphisa ukuguquguquka kwetorque, ngaloo ndlela kuphuculwe ukusebenza kakuhle koguqulo lwamandla kunye nokuzinza kokusebenza kwayo yonke inkqubo yesitaki. Ukuba i-magnetic field consistency deviation inkulu kakhulu, iya kubangela iingxaki ezifana nokugijima kunye nokufudumeza ngexesha lokusebenza kwemoto, echaphazela kakhulu ukusebenza okuqhelekileyo kwenkqubo.
Iimfuno zezinto eziphathekayo
I-rotor magnetic material yiSmCo, Isixhobo semagnethi esisigxina somhlaba esinqabileyo esinezibonelelo zemveliso yamandla ombane aphezulu, amandla anyanzelwayo aphezulu kunye nokuzinza okuhle kobushushu. Kwindawo yokusebenza ye-hydrogen fuel cell stack, inokubonelela ngemagnethi ezinzileyo kwaye ixhathise impembelelo yokutshintsha kweqondo lobushushu kumandla wemagnethi ukuya kwinqanaba elithile. Impahla ye-sheath yi-GH4169 (inconel718), eyi-alloy esekelwe kwi-nickel ephezulu. Inamandla abalaseleyo obushushu obuphezulu, ukumelana nokudinwa kunye nokuxhathisa ukubola. Iyakwazi ukukhusela ngokufanelekileyo imagnethi kwindawo yeekhemikhali eziyinkimbinkimbi kunye neemeko eziphezulu zokusebenza kweqondo lokushisa kweeseli ze-hydrogen fuel, zithintele kwi-corrosion kunye nomonakalo womatshini, kunye nokuqinisekisa ukusebenza okuzinzile kwexesha elide le-rotor.
2. Indima yerotor
I-rotor yenye yezinto eziphambili zokusebenza komatshini. Iqhuba i-impeller ukuba ifake kwaye icinezele umoya wangaphandle ngokujikeleza kwe-high-speed, iqonda ukuguqulwa phakathi kwamandla ombane kunye namandla omatshini, kwaye inika i-oksijini eyaneleyo ye-cathode ye-stack. Ioksijini yinto ebalulekileyo yokusabela kwi-electrochemical reaction of fuel cells. Ukubonelela ngeoksijini okwaneleyo kunokunyusa isantya sokuphendula kwe-electrochemical reaction, ngaloo ndlela kunyuse ukuveliswa kwamandla kwesitaki kunye nokuqinisekisa inkqubela phambili egudileyo yoguqulo lwamandla kunye nokuphuma kwamandla kuyo yonke inkqubo ye-hydrogen ye-fuel stack.
3. Ulawulo olungqongqo lwemveliso kunyeukuhlolwa komgangatho
Amandla eMagnet eHangzhouinobuchwepheshe obuphambili kunye neenkqubo kwimveliso ye-rotor.
Inamava atyebileyo kunye nokuqokelela kobugcisa kulawulo lokubunjwa kunye ne-microstructure yeemagnethi ze-SmCo. Iyakwazi ukulungiselela iimagnethi ze-ultra-high ze-SmCo ezinokumelana nobushushu be-550 ℃, imagnethi kunye ne-magnetic field consistency ngaphakathi kwe-1%, kunye neemagnethi zangoku ezichasene ne-eddy zokuqinisekisa ukuba ukusebenza kweemagnethi kwandiswa.
Kwinkqubo yokucubungula kunye nokuveliswa kwe-rotor, izixhobo zokulungiswa kwe-CNC ezichanekileyo zisetyenziselwa ukulawula ngokuchanekileyo ukuchaneka kwe-dimensional yamagnethi kunye nokuchaneka komgangatho we-rotor, ukuqinisekisa ukusebenza kwe-balance balance kunye neemfuno zokuhambelana kwemagnethi ye-rotor. Ukongeza, kwi-welding kunye nokwenza inkqubo ye-sleeve, iteknoloji ye-welding ephezulu kunye nenkqubo yokunyanga ukushisa isetyenziselwa ukuqinisekisa ukudibanisa okusondeleyo kwe-GH4169 sleeve kunye nemagnethi kunye neempawu ze-mechanical ze-sleeve.
Ngokomgangatho, inkampani inesethi epheleleyo kunye nechanekileyo yezixhobo zokuvavanya kunye neenkqubo, isebenzisa izixhobo ezahlukeneyo zokulinganisa ezifana ne-CMM ukuqinisekisa ukuma kunye nokunyamezela isikhundla se-rotor. I-speedometer ye-Laser isetyenziselwa ukukhangela isantya se-rotor ukubamba ngokuchanekileyo idatha yesantya se-rotor xa ijikeleza ngesantya esiphezulu, inika inkqubo ngesiqinisekiso sedatha ethembekileyo.
Umatshini wokufumanisa ukulinganisa okunamandla: I-rotor ifakwe kumatshini wokufumanisa, kwaye umqondiso we-vibration we-rotor uqokelelwa ngexesha langempela nge-sensor ngexesha lokujikeleza. Emva koko, ezi zibonakaliso zicutshungulwa ngokunzulu yinkqubo yokuhlalutya idatha ukubala ukungalingani kwe-rotor kunye nolwazi lwesigaba. Ukufumanisa ukuchaneka kwayo kunokufikelela kwi-G2.5 okanye nakwi-G1. Isisombululo sokufumanisa ukungalingani sinokuchaneka kwinqanaba le-milligram. Emva kokuba i-rotor ifunyenwe ingalingani, inokulungiswa ngokuchanekileyo ngokusekelwe kwidatha yokufumanisa ukuze kuqinisekiswe ukuba ukusebenza kokulinganisela okuguquguqukayo kwe-rotor kufinyelela kwindawo engcono kakhulu.
Isixhobo sokulinganisa intsimi yemagnethi: Inokubona ngokupheleleyo amandla omhlaba wemagnethi, usasazo lwemagnethi kunye nemagnethi ukuhambelana kwerotor. Isixhobo sokulinganisa sinokwenza isampuli zamanqaku amaninzi kwiindawo ezahlukeneyo ze-rotor, kwaye ubale i-magnetic field consistency devitency value ngokuthelekisa idatha yemagnethi yendawo nganye ukuqinisekisa ukuba ilawulwa ngaphakathi kwe-1%.
Inkampani ayinayo kuphela imveliso enamava kunye neqela elinobuchule, kodwa ineqela lophando kunye neqela lophuhliso elinokuthi liqhube kakuhle kwaye lihlaziye inkqubo yoyilo kunye nokuveliswa kwe-rotor ukuhlangabezana neemfuno zemarike ehlala iguquka. Okwesibini, i-Hangzhou Magnet Power Technology Co., Ltd. inokubonelela abathengi ngezisombululo ezikhethekileyo zerotor ezisekelwe kwiimeko ezahlukeneyo zabasebenzisi kunye neemfuno, kudityaniswe neminyaka yamava oshishino, ulawulo olungqongqo lwemathiriyeli ekrwada, ukusungulwa kwetekhnoloji kunye nophuhliso, kunye nokuhlolwa komgangatho ukuqinisekisa. ukuba yonke i-rotor ehanjiswa kubathengi iyimveliso ekumgangatho ophezulu.
