I. Ukwethulwa kwemoto enesivinini esikhulu
Injini enesivinini esikhulu imvamisa ibhekisa enjinini ijubane layo elingaphezu kuka-10000 r/min. Ama-motor anesivinini esiphezulu mancane ngosayizi, angaxhunywa ngokuqondile emithwalweni enesivinini esikhulu, aqede isidingo samadivayisi endabuko okwandisa isivinini somshini, ukunciphisa umsindo wesistimu nokuthuthukisa ukusebenza kahle kokudluliswa kwesistimu. Njengamanje, izinjini zokungeniswa, izinjini zikazibuthe ezihlala njalo kanye nama-switched reluctance motors yizona ezifinyelele isivinini esikhulu ngempumelelo.
Izici eziyinhloko zamamotho anesivinini esiphezulu isivinini se-rotor, i-high stator winding current kanye ne-flux frequency emnyombweni, ukuminyana kwamandla aphezulu kanye nokulahlekelwa kwabantu. Lezi zici zinquma ukuthi injini enesivinini esikhulu inokwehluka kobuchwepheshe obuhlukile benjini yesivinini esiyingqayizivele nezindlela zokuklama, ubunzima bokwakheka kanye nokukhiqiza kuvame ukuba bukhulu ngokwedlulele kunenjini yesivinini esivamile.
Izicelo zamamotho anesivinini esikhulu.
( 1) Amamotho anesivinini esiphezulu asetshenziswa ezintweni ezehlukene ezifana nama-centrifugal compressor ama-air conditioner noma amafriji.
(2) Ngokuthuthukiswa kwezimoto eziyingxube embonini yezimoto, kuzonikezwa usayizi omncane nesisindo esilula ujeneretha wesivinini esikhulu. ukunakwa okugcwele futhi babe nethuba elihle lokufaka isicelo emkhakheni wezimoto eziyingxubevange, ezondiza, imikhumbi, njll.
(3) Amajeneretha anesivinini esiphezulu ashayelwa izinjini zegesi mancane ngosayizi futhi ahamba kahle, futhi angasetshenziswa njengesipele. umthombo wamandla kwezinye izinsiza ezibalulekile, noma njengomthombo wamandla ozimele noma isiteshi sikagesi esincane ukuvala isikhala sokushoda kwamandla aphakathi nendawo, anenani elibalulekile elingokoqobo.
Okwesibili, isimo sokuthuthukiswa kwezimoto ngesivinini esiphezulu ekhaya naphesheya
1, I-motor-speed induction motor
Isakhiwo se-rotor ye-Induction silula, inertia ejikelezayo ephansi, futhi ingagijima isikhathi eside ezingeni lokushisa eliphezulu kanye nesivinini esikhulu, ngakho-ke injini yokungenisa isetshenziswa kabanzi emkhakheni wesivinini esikhulu. .
Okwamanje, injini engenisa isivinini esiphezulu yasekhaya nezangaphandle, amandla angu-15MW amakhulu kunawo wonke, isivinini sayo esingu-20000 r/min, yenzelwe i-ABB ngo-2002, kusetshenziswa isakhiwo esiqinile se-rotor. Isivinini se-high-speed motor induction motor ngesikhulu kunazo zonke esakhiwe yi-Westwind Air Bearings, isivinini esingu-300000 r/min, amandla ayo angu-200 W, asetshenziselwa ukuphotha umshini wokumba i-PCB. Ngokufanayo, injini yokungenisa enesivinini esiphezulu enamandla angu-10 kW kanye nesivinini esingu-180,000 r/min iye yatholakala emazweni angaphandle ukuze isetshenziswe njengenjini yokuhlola.
Isithombe esingezansi sibonisa injini yokungenisa enesivinini esiphezulu eyakhiwe yi-Westwind Air. Amabhereli anamandla angu-200 W kanye nesivinini esingu-300,000 r/min.
Ucwaningo lwasekhaya luhlehle kancane, phakathi kwalo iShenyang University of Technology, iChongqing Dema Electric, iNaval Engineering University, iNyuvesi yaseZhejiang kanye namanye amayunithi ocwaningo enze ucwaningo. umsebenzi omningi wocwaningo mayelana nezinjini zokungeniswa ngesivinini esiphezulu.
I-Chongqing I-Dema Motor ithuthukise u-100kW, 25000r/min injini yokungenisa enesivinini esiphezulu. I-Shenyang University of Technology yenze ucwaningo ngamamotho angenisa isivinini esiphezulu anamandla angu-280kW, isivinini esingu-12000r/min, isivinini esingu-132m/s somugqa kanye nesakhiwo esivamile esinama-laminated. I-Naval Engineering University yenze ucwaningo ngamamotho anesivinini esiphezulu angu-2.5 MW, njll.
2,Injini enozibuthe enesivinini esiphezulu
Amamotho kazibuthe ahlala njalo adumile ezisetshenziswa zejubane eliphezulu ngenxa yokusebenza kahle kwawo okuphezulu, okuphezulu. isici samandla kanye nebanga elikhulu lesivinini. Uma kuqhathaniswa nerotha yangaphandle enozibuthe injini ehlala unomphela, injini yamazibuthe engaphakathi yerotha inezinzuzo zerediyasi encane kanye nokwethembeka okuphezulu, ibe inketho yokuqala yamamotho anesivinini esikhulu.
Okwamanje, phakathi kwezinjini zikazibuthe ezinesivinini esiphezulu ekhaya nakwamanye amazwe, injini enamandla kakhulu enozibuthe enesivinini esiphezulu iyacwaningwa e-United States, inamandla angu-8MW kanye nesivinini esingu-15000r/min. Kuyirotha kazibuthe ebekwe ngobuso enomkhono ovikelayo we-carbon fibre kanye nesistimu yokupholisa esebenzisa inhlanganisela yokupholisa umoya kanye nokupholisa ngamanzi kumamotho anesivinini esiphezulu ahambisana nezinjini zegesi.
I-Swiss ETH Zurich idizayine isivinini esiphezulu sejubane eliphezulu unomphela uzibuthe motor. Amapharamitha angu-500000 r/min, amandla angu-1kW, isivinini somugqa ngu-261m/s, futhi kusetshenziswa ibhantshi elivikela ingxubevange. Harbin Institute of Technology, Harbin Institute of Technology, Xi'an Jiaotong University, Nanjing Aerospace Motor, Southeast University, Beijing University of Aeronautics and Astronautics, Jiangsu University, Beijing Jiaotong University, Guangdong University of Technology, CSR Zhuzhou Motor Co.
Benze ucwaningo ngezici zokuklama, izici zokulahlekelwa, amandla e-rotor nokubala kokuqina, kanye nomklamo wesistimu yokupholisa kanye nokubala kokukhuphuka kwezinga lokushisa kwamamotho anesivinini esikhulu, futhi bakhiqize ama-prototypes anesivinini esikhulu wamakilasi ahlukene amandla kanye nesivinini.
3, Ukushintsha izinjini ezinqena ukushintsha
Izinjini ezinqenayo ezishintshiwe zidonsa ukunaka ngesakhiwo sazo esilula, ukuqina, izindleko eziphansi kanye nokumelana nezinga lokushisa eliphezulu, futhi ziya ngokuya zisetshenziswa ezinhlelweni zejubane eliphezulu.
Amandla aphezulu esivinini esikhulu Injini eshintshayo enqenayo ingu-250kW kanti ijubane lingu-22000r/min, kanti isivinini esiphezulu ngu-200000r/min futhi amandla angu-1kW.
Nanjing University of Aeronautics and Astronautics, Beijing Jiaotong University kanye ne-Huazhong University of Science and Technology akwenzile. umsebenzi wocwaningo mayelana nezinjini zokuthikaza ezishintshwayo ezinesivinini esikhulu, phakathi kwazo iNanjing University of Aeronautics and Astronautics ithuthukise i-1 kW, 130,000 r/min switched
Izikhombisi-ndlela eziyinhloko zocwaningo nentuthuko zamamotho anesivinini yilezi.
Ucwaningo izingqinamba eziyinhloko zamandla aphezulu wemoto enesivinini esikhulu kanye ne-ultra-high speed motor motor; idizayini ehlanganisiwe esekelwe emkhakheni wezinto eziningi zomzimba kanye neziyalo eziningi; ucwaningo lwethiyori nokuqinisekiswa kokuhlolwa kokulahleka kwe-stator-rotor; ukuthuthukiswa kanye nokusetshenziswa kwezinto ezintsha ezifana ne-magnetic materials unomphela enamandla amakhulu nokumelana nokushisa okuphezulu, izinto ze-fiber ezine-conductivity ephezulu ye-thermal; ucwaningo ngezinto ezisezingeni eliphakeme ze-rotor laminated kanye nesakhiwo; ukusetshenziswa kwama-bearings anesivinini esiphezulu ngaphansi kwamazinga ahlukene kanye nesivinini; ukushabalalisa ukushisa okuhle Idizayini yesistimu yokulawula isivinini esikhulu; Ukuthuthukiswa kokucubungula okusha kwe-rotor kanye nobuchwepheshe bokuhlanganisa ukuze kuhlangatshezwane nezidingo zezimboni, njll.
