Ama-rotor anesivinini esikhulu: Qoqa amandla ozibuthe ukuze udale umhlaba osebenza kahle kakhudlwana

Eminyakeni yamuva, ama-motor anesivinini esikhulu athuthuke ngokushesha (isivinini ≥ 10000RPM). Njengoba okuhloswe ukuncishiswa kwekhabhoni kuqashelwa amazwe ahlukahlukene, amamotho anesivinini esikhulu asetshenziswe ngokushesha ngenxa yezinzuzo zawo ezinkulu zokonga amandla. Ziye zaba izingxenye eziyinhloko zokushayela emikhakheni yama-compressor, ama-blower, amaphampu e-vacuum, njll. Izingxenye eziyinhloko zama-motor anesivinini esikhulu ngokuyinhloko: ama-bearings, ama-rotor, ama-stator, nezilawuli. Njengengxenye ebalulekile yamandla enjini, i-rotor idlala indima eyinhloko. Zisetshenziswa kabanzi emishinini nasezinsizeni ezahlukahlukene ngokusebenza kwazo okuhle kakhulu kanye nekhwalithi enhle kakhulu. Ngenkathi iletha ukukhiqiza okuphumelelayo emabhizinisini, abuye aguqule izimpilo zabantu. Njengamanje, ama-motor anesivinini esikhulu asetshenziswa kabanzi emakethe ikakhulukazi:izinjini ezithwala kazibuthe, izinjini ezithwala umoyafuthiuwoyela ezishelelayo ezithwala izinjini.

Okulandelayo, ake sihlolisise izici ze-rotor ezimweni ezahlukene zokusetshenziswa:

1. Magnetic bearing motor

Irotha yemoto kazibuthe ethwele imisiwe ku-stator ngamandla kazibuthe kagesi akhiqizwe ibheringi kazibuthe, igwema ukungqubuzana kokuthintana kwamabheringi emishini yendabuko. Lokhu kwenza injini icishe ingagqoki ngomshini ngesikhathi sokusebenza, inciphisa izindleko zokuyilungisa, futhi ingafinyelela ukusebenza ngesivinini esikhulu. Ngezinzwa nezinhlelo zokulawula, ukunemba kwesikhundla se-rotor kungalawulwa ezingeni le-micron. Ngenxa yokuthi amabheringi kazibuthe asebenzayo ngokuvamile asetshenziswa, izinjini ezithwala kazibuthe zinezinzuzo ezisobala ebangeni lamandla aphezulu angu-200kW-2MW. Ukuthatha i-compressor yesiqandisi esithwala kazibuthe njengesibonelo, ngenxa yokuba khona kokungqubuzana kwemishini, ama-compressor endabuko awagcini nje ngokusetshenziswa kwamandla aphezulu, kodwa futhi nomsindo omkhulu nokuphila okulinganiselwe. Ukusetshenziswa kwe-magnetic bearing refrigeration compressors kuzixazulula ngokuphelele lezi zinkinga. Ingakwazi ukucindezela isiqandisi ngendlela ephumelela kakhudlwana, ithuthukise kakhulu ukusebenza kahle kwamandla kwesistimu yesiqandisi, futhi inciphise ukusetshenziswa kwamandla kwemishini yesiqandisi yasendlini neyezentengiselwano (yonga amandla kagesi 30%). Ngesikhathi esifanayo, ukusebenza komsindo ophansi futhi kudala indawo ethulile nenethezeke kakhudlwana kubasebenzisi, kungaba kuma-air conditioner asekhaya noma ezindaweni ezibandayo zokuthengisa ezinkulu, kungaletha ulwazi oluhle lomsebenzisi. Izinkampani ezaziwayo ezifana neMidea, Gree, noHaier zisebenzisa lobu buchwepheshe.

2. Injini yomoya

I-rotor ye-air bearing motor imisiwe ngama-air bearings. Ngesikhathi sokuqala nokusebenza kwe-motor, umoya ozungeza i-rotor usebenzisa ukucindezela komoya okukhiqizwa ukujikeleza kwesivinini esikhulu ukumisa i-rotor, ngaleyo ndlela kunciphise ukungqubuzana phakathi kwe-rotor ne-stator nokunciphisa ukulahlekelwa. I-rotor ye-air bearing motor ingagijima ngokuzinza ngesivinini esiphezulu. Ebangeni lamandla amancane angu-7.5kW-500kW, injini ethwala umoya inezinzuzo ngenxa yobukhulu bayo kanye nesivinini esikhulu. Ngenxa yokuthi i-coefficient ye-friction ye-air bear yehla ngokunyuka kwesivinini, ukusebenza kahle kwemoto kusengagcinwa kusezingeni eliphezulu ngesivinini esikhulu. Lokhu kwenza i-air bear

amamotho asetshenziswa kakhulu kwezinye izinhlelo zokungenisa umoya noma zokucindezelwa kwegesi ezidinga isivinini esikhulu nokugeleza okukhulu, njengemishini yokuhlanza igesi engcolile yezimboni, izifutha-moya zamathangi okukhuculula indle, ama-compressor wezinhlelo ze-hydrogen fuel cell, njll. Indawo yokusebenza ye-air bearingmotor umoya. , engenayo ingozi yokuvuza kwamafutha njengama-bearings agcotshwe ngamafutha, futhi ingabangeli ukungcoliswa kwamafutha endaweni yokusebenza. Lokhu kunobungane kakhulu ezimbonini ezinezidingo eziphezulu zemvelo yokukhiqiza, njengokucubungula ukudla, izinsiza zezokwelapha kanye neminye imikhakha.

3. Injini eslayidayo

Ku-sliding bearing motor, ukusetshenziswa kwama-sliding bearings kuvumelai-rotorukuzungezisa ngesivinini esikhulu ngamandla amakhulu (njalo ≥500kW). I-rotor iphinde ibe ingxenye eyinhloko ejikelezayo yenjini, ekhiqiza itorque ejikelezayo ngokusebenzisana nenkundla kazibuthe ye-stator ukuze ishayele umthwalo usebenze. Izinzuzo eziyinhloko ukusebenza okuzinzile nokuqina. Isibonelo, ku-motor yepompo enkulu yezimboni, ukujikeleza kwe-rotor kushayela i-pump shaft, okuvumela uketshezi ukuba luhanjiswe. I-rotor ijikeleza ku-sliding bear, ehlinzeka ngokusekela i-rotor futhi ithwala amandla e-radial kanye ne-axial ye-rotor. Lapho isivinini se-rotor nomthwalo kungaphakathi kwebanga elicacisiwe, i-rotor ijikeleza kahle ekuthwaleni, okunganciphisa ukudlidliza nomsindo. Isibonelo, kwezinye izinqubo zokukhiqiza zezimboni ezidinga ukuzinza okuphezulu kokusebenza, njengokwenza iphepha, izindwangu nezinye izimboni, ama-sliding bearing motors angaqinisekisa ukuqhubeka kokukhiqiza kanye nekhwalithi yomkhiqizo.

4. Isifinyezo

Ukusetshenziswa nokuthuthukiswa kwama-rotor anesivinini esikhulu kulethe amathuba nezinguquko ezimbonini eziningi. Kungakhathaliseki ukuthi izinjini ezithwala kazibuthe, izinjini ezithwala umoya noma izinjini ezislayidayo, zonke zidlala indima ebalulekile emikhakheni yazo yohlelo lokusebenza futhi zixazulule izinkinga eziningi ezibhekene namamotho endabuko.

I-Hangzhou Magnet Power Technology Co., Ltd.ayigcinanga ngokuba ingcweti kobuchwepheshe obunegunya lobunikazi obungaphezu kuka-20 ngokutshalwa kwezimali ku-R&D, ukulawula ukukhiqizwa kwekhwalithi yomkhiqizo kanye nesistimu yesevisi ephelele yangemva kokuthengisa, kodwa futhi inikeza imikhiqizo ezinzile nethembekile yengxenye kazibuthe kubalingani abaningi basekhaya nabangaphandle.
