Phakathi kwezingxenye zokusebenza ze-hydrogen fuel cell stacks kanye ne-air compressors, i-rotor iyisihluthulelo somthombo wamandla, futhi izinkomba zayo ezihlukahlukene zihlobene ngokuqondile nokusebenza kahle nokuzinza komshini ngesikhathi sokusebenza.
1. Izidingo ze-rotor
Izidingo zesivinini
Isivinini sidinga ukuthi sibe ngu-≥100,000RPM. Isivinini esikhulu siwukuhlangabezana nokugeleza kwegesi kanye nezidingo zengcindezi yezitaki ze-hydrogen fuel cell kanye nama-compressor emoyeni ngesikhathi sokusebenza. Kumaseli e-hydrogen fuel, i-compressor yomoya idinga ukucindezela ngokushesha inani elikhulu lomoya futhi iwuhambise ku-cathode yesitaki. I-rotor enesivinini esikhulu ingaphoqa umoya ukuthi ungene endaweni yokusabela ngokugeleza okwanele nokucindezela ukuze kuqinisekiswe ukusabela okusebenzayo kwe-fuel cell. Isivinini esinjalo sinezindinganiso eziqinile zamandla wezinto ezibonakalayo, inqubo yokukhiqiza kanye nebhalansi eguquguqukayo ye-rotor, ngoba lapho ijikeleza ngesivinini esikhulu, i-rotor kufanele imelane namandla amakhulu e-centrifugal, futhi noma yikuphi ukungalingani okuncane kungabangela ukudlidliza okukhulu noma ukulimala kwengxenye.
Izidingo zebhalansi enamandla
Ibhalansi eguqukayo idinga ukufinyelela izinga le-G2.5. Ngesikhathi sokujikeleza kwesivinini esikhulu, ukusatshalaliswa okukhulu kwe-rotor kumele kube okufanayo ngangokunokwenzeka. Uma ibhalansi eguquguqukayo ingalungile, i-rotor izokhiqiza amandla e-centrifugal etshekile, okungeke kubangele kuphela ukudlidliza nomsindo wemishini, kodwa futhi kwandise ukuguga kwezingxenye ezifana nama-bearings, futhi kunciphise impilo yesevisi yemishini. Ukulinganisa okunamandla kuya kuzinga le-G2.5 kusho ukuthi ukungalingani kwe-rotor kuzolawulwa ngaphakathi kwebanga eliphansi kakhulu ukuze kuqinisekiswe ukuzinza kwe-rotor ngesikhathi sokujikeleza.
Izidingo zokungaguquguquki kwenkundla kazibuthe
Isidingo sokungaguquguquki kwenkundla kazibuthe ngaphakathi kwe-1% ikakhulukazi ngama-rotor anozibuthe. Ohlelweni lwezithuthuthu oluhlobene nezitaki ze-hydrogen fuel cell, ukufana nokuzinza kwendawo kazibuthe kunethonya eliwujuqu ekusebenzeni kwenjini. Ukungaguquguquki kwenkundla kazibuthe okunembile kungaqinisekisa ukushelela kwe-torque ye-motor futhi kunciphise ukuguquguquka kwe-torque, ngaleyo ndlela kuthuthukise ukusebenza kahle kokuguqulwa kwamandla kanye nokuzinza kokusebenza kwalo lonke uhlelo lwesitaki. Uma ukuchezuka kokungaguquguquki kwenkundla kazibuthe kukukhulu kakhulu, kuzodala izinkinga ezifana nokugijima nokushisa ngesikhathi sokusebenza kwemoto, kuthinte kabi ukusebenza okuvamile kwesistimu.
Izidingo zezinto ezibonakalayo
I-rotor magnetic materialI-SmCo, izinto ezingavamile zikazibuthe zomhlaba ezihlala unomphela ezinezinzuzo zomkhiqizo wamandla kazibuthe aphezulu, amandla aphoqelelayo aphezulu nokuzinza okuhle kwezinga lokushisa. Endaweni yokusebenza ye-hydrogen fuel cell stack, inganikeza inkambu kazibuthe ezinzile futhi imelane nomthelela wokushintsha kwezinga lokushisa kumandla kazibuthe ngokwezinga elithile. Impahla ye-sheath yi-GH4169 (inconel718), okuyi-alloy esekelwe ku-nickel esebenza kakhulu. Inamandla amahle kakhulu okushisa aphezulu, ukumelana nokukhathala kanye nokumelana nokugqwala. Ingakwazi ukuvikela ngempumelelo uzibuthe endaweni eyinkimbinkimbi yamakhemikhali kanye nezimo eziphakeme zokushisa zokusebenza kwamaseli e-hydrogen fuel, ukuyivimbela ekulimaleni nasekulimeni kwemishini, futhi iqinisekise ukusebenza okuzinzile kwesikhathi eside kwe-rotor.
2. Indima ye-rotor
I-rotor ingenye yezingxenye eziyinhloko zokusebenza komshini. Iqhuba i-impeller ukuthi ihogele futhi icindezele umoya wangaphandle ngokuzungezisa ngesivinini esikhulu, ibona ukuguqulwa phakathi kwamandla kagesi namandla emishini, futhi inikeza umoya-mpilo owanele we-cathode yesitaki. Umoya-mpilo uyisabeli esibalulekile ekuphenduleni kwe-electrochemical yamaseli kaphethiloli. Ukunikezwa komoyampilo owanele kungakhuphula izinga lokusabela kwe-electrochemical, ngaleyo ndlela kwandise ukuphehlwa kwamandla kwesitaki nokuqinisekisa ukuqhubeka kahle kokuguqulwa kwamandla kanye nokuphuma kwamandla kwalo lonke uhlelo lwesitaki se-hydrogen fuel.
3. Ukulawulwa okuqinile kokukhiqiza kanyeukuhlolwa kwekhwalithi
I-Hangzhou Magnet Powerinobuchwepheshe obuthuthukisiwe kanye nezinqubo ekukhiqizeni ama-rotor.
Inolwazi olucebile kanye nokuqongelela kobuchwepheshe ekulawuleni ukwakheka kanye nesakhiwo esincane samagnethi we-SmCo. Iyakwazi ukulungisa omazibuthe be-SmCo abasezingeni eliphezulu kakhulu abanokumelana nezinga lokushisa okungama-550 ℃, omagnethi abanenkambu kazibuthe engaguquguquki ngaphakathi kwe-1%, kanye nozibuthe bamanje abalwa ne-eddy ukuze kuqinisekiswe ukuthi ukusebenza kwezidonsa kuyakhuliswa.
Enqubweni yokucubungula nokukhiqiza ye-rotor, imishini yokucubungula ye-CNC enembayo ephezulu isetshenziselwa ukulawula ngokunembile ukunemba kobukhulu bamamagnethi kanye nokunemba kobukhulu berotha, iqinisekisa ukusebenza kwebhalansi okuguquguqukayo kanye nezidingo zokungaguquguquki kwensimu kazibuthe yerotha. Ukwengeza, ohlelweni lokushisela kanye nokwakheka komkhono, ubuchwepheshe bokushisela obuphambili kanye nenqubo yokwelapha ukushisa kusetshenziswa ukuze kuqinisekiswe inhlanganisela eseduze yomkhono we-GH4169 kanye nozibuthe kanye nezakhiwo zemishini zomkhono.
Ngokuya ngekhwalithi, inkampani inesethi ephelele nenembile yemishini yokuhlola nezinqubo, isebenzisa imishini yokulinganisa ehlukahlukene efana ne-CMM ukuqinisekisa ukubunjwa nokubekezelelana kwesikhundla se-rotor. I-speedometer ye-Laser isetshenziselwa ukutholwa kwesivinini se-rotor ukuze ithwebule ngokunembile idatha yesivinini se-rotor lapho ijikeleza ngesivinini esikhulu, ihlinzeka uhlelo ngesiqinisekiso esithembekile sedatha yesivinini.
Umshini wokuthola ukulinganisa okunamandla: I-rotor ibekwa emshinini wokuthola, futhi isignali yokudlidliza ye-rotor iqoqwa ngesikhathi sangempela ngenzwa ngesikhathi sokuzungezisa. Khona-ke, lezi zimpawu zicutshungulwa ngokujulile uhlelo lokuhlaziya idatha ukuze kubalwe ukungalingani kwe-rotor nolwazi lwesigaba. Ukunemba kokutholwa kwayo kungafinyelela ku-G2.5 noma ku-G1. Isixazululo sokuthola ukungalingani singanemba kuze kufike ezingeni le-milligram. Uma i-rotor itholwa ukuthi ayilingani, ingalungiswa ngokunembile ngokusekelwe kudatha yokuthola ukuze kuqinisekiswe ukuthi ukusebenza kwebhalansi okuguquguqukayo kwe-rotor kufinyelela kusimo esihle kakhulu.
Ithuluzi lokulinganisa inkambu kazibuthe: Ingakwazi ukubona ngokugcwele amandla kazibuthe, ukusatshalaliswa kwendawo kazibuthe kanye nokungaguquguquki kwendawo kazibuthe. Ithuluzi lokulinganisa lingenza isampula lamaphuzu amaningi ezindaweni ezihlukene ze-rotor, futhi libale inani lokuchezuka kokungaguquguquki kwendawo kazibuthe ngokuqhathanisa idatha yenkundla kazibuthe yephoyinti ngalinye ukuze kuqinisekiswe ukuthi ilawulwa ngaphakathi kuka-1%.
Le nkampani ayinayo kuphela ithimba lokukhiqiza elinolwazi namakhono, kodwa futhi inethimba locwaningo nentuthuko elingase lithuthukise ngokuqhubekayo futhi lisungule inqubo yokuklama nokukhiqiza i-rotor ukuze ihlangabezane nezidingo zemakethe ehlala ishintsha. Okwesibili, i-Hangzhou Magnet Power Technology Co., Ltd. ingahlinzeka amakhasimende ngezixazululo ezikhethekile ze-rotor ezenziwe ngezifiso ezisekelwe ezimweni ezihlukile zabasebenzisi kanye nezidingo, kuhlanganiswe neminyaka yesipiliyoni sembonini, ukulawula okuqinile kwezinto zokusetshenziswa, ukuqanjwa kabusha kwezobuchwepheshe kanye nentuthuko, nokuhlolwa kwekhwalithi ukuqinisekisa ukuthi yonke i-rotor elethwa kumakhasimende ingumkhiqizo wekhwalithi ephezulu.
