Kwiminyaka yakutshanje, ii-motor-speed-speed motors ziye zaphuhliswa ngokukhawuleza (isantya ≥ 10000RPM). Njengoko iithagethi zokunciphisa ikhabhoni zibonwa ngamazwe ahlukeneyo, iimotor ezinesantya esiphezulu zisetyenziswe ngokukhawuleza ngenxa yeenzuzo zazo ezinkulu zokonga amandla. Baye baba ngamacandelo angundoqo okuqhuba kwiindawo zokuxinzelela, ii-blowers, iimpompo ze-vacuum, njl. Amacandelo angundoqo eenjini ezihamba ngesantya esiphezulu kakhulu: iibheringi, i-rotors, i-stators, kunye nabalawuli. Njengenxalenye yamandla ebalulekileyo yemoto, i-rotor idlala indima ephambili. Zisetyenziswa ngokubanzi koomatshini abahlukeneyo kunye nezixhobo kunye nokusebenza kwazo okugqwesileyo kunye nomgangatho obalaseleyo. Ngelixa ezisa imveliso esebenzayo kumashishini, ayabutshintsha ubomi babantu. Okwangoku, iinjini ezinesantya esiphezulu ezisetyenziswa kakhulu kwintengiso ikakhulu:iinjini zokuthwala imagnethi, iinjini zomoyakwayeiinjini zokutyibilika kweoli.
Okulandelayo, makhe sijonge ngakumbi kwiimpawu zerotor kwiimeko ezahlukeneyo zokusetyenziswa:
1. Injini yokuthwala imagnethi
I-rotor yemoto enemagnethi inqunyanyiswa kwi-stator ngokusebenzisa amandla e-electromagnetic eveliswa yi-magnetic bearing, ithintela ukungqubana kweebheringi zoomatshini bemveli. Oku kwenza ukuba i-motor iphantse ingabi nampahla yokunxiba ngexesha lokusebenza, inciphisa iindleko zokuyilungisa, kwaye inokufikelela kwisantya esiphezulu sokusebenza. Ngokusebenzisa i-sensor kunye neenkqubo zokulawula, ukuchaneka kwesikhundla se-rotor kunokulawulwa kwinqanaba le-micron. Kuba iibheringi zemagnethi ezisebenzayo zisetyenziswa ngokubanzi, iimotor ezithwala imagnethi zineengenelo ezicacileyo kuluhlu lwamandla aphezulu angama-200kW-2MW. Ukuthatha icompressor yesikhenkcezisi esinemagnethi njengomzekelo, ngenxa yobukho bokungqubana koomatshini, iicompressor zemveli azinawo amandla aphezulu kuphela, kodwa kunye nengxolo ephezulu kunye nobomi obulinganiselweyo. Ukusetyenziswa kwe-magnetic bearing compressors refrigeration kusombulula ngokugqibeleleyo ezi ngxaki. Iyakwazi ukucinezela ifriji ngendlela efanelekileyo, iphucule kakhulu amandla ombane wenkqubo yefriji, kunye nokunciphisa ukusetyenziswa kwamandla kwendlu kunye nezixhobo zefriji zentengiso (ukugcina amandla ombane 30%). Kwangaxeshanye, ukusebenza kwengxolo ephantsi kukwadala indawo ezolileyo kunye nekhululekileyo kubasebenzisi, nokuba kukwizifudumezi zomoya zasekhaya okanye iindawo zokugcina ezibandayo zentengiso, kunokuzisa amava alungileyo kumsebenzisi. Iinkampani ezaziwayo ezifana neMidea, Gree, kunye neHaier zisebenzisa le teknoloji.
2. Injini yomoya
I-rotor ye-motor ethwele umoya inqunyanyiswe ngeebheringi zomoya. Ngethuba lokuqala kunye nokusebenza kwe-motor, umoya ojikelezayo we-rotor usebenzisa uxinzelelo lomoya oluveliswa ngokujikeleza kwe-high-speed ukumisa i-rotor, ngaloo ndlela ukunciphisa ukungqubuzana phakathi kwe-rotor kunye ne-stator kunye nokunciphisa ilahleko. I-rotor yemoto ethwele umoya inokubaleka ngokuzinzileyo kwisantya esiphezulu. Kuluhlu lwamandla oluncinci lwe-7.5kW-500kW, i-motor ephethe umoya ineenzuzo ngenxa yobukhulu bayo obuncinci kunye nesantya esiphezulu. Ngenxa yokuba i-coefficient ye-friction ye-air bear iyancipha ngokunyuka kwesantya, ukusebenza kakuhle kwemoto kusenokugcinwa kwinqanaba eliphezulu ngesantya esiphezulu. Oku kwenza ukuthwala umoya
iinjini ezisetyenziswa ngokubanzi kwezinye iinkqubo zokuphefumla umoya okanye ucinezelo lwerhasi ezifuna isantya esiphezulu kunye nokuhamba okukhulu, ezifana nezixhobo zokucoca igesi yenkunkuma kwimizi-mveliso, izivutheli zokuphefumla kwiitanki zogutyulo, iicompressors zeenkqubo ze-hydrogen fuel cell, njl. njl. , engenawo umngcipheko wokuvuza kweoli njengeebheringi ze-oyile-lubricated, kwaye ayibangeli ukungcoliswa kweoli kwindawo yokusebenza. Oku kunobubele kakhulu kumashishini aneemfuno eziphezulu zommandla wemveliso, ezifana nokulungiswa kokutya, izixhobo zonyango kunye nezinye iindawo.
3. Ukutyibilika kwemoto
Kwi-sliding bearing motor, ukusetyenziswa kweebheringi zokutyibilika kuvumela ii-rotorukujikeleza ngesantya esiphezulu ngamandla aphezulu (rhoqo ≥500kW). I-rotor ikwayinxalenye engundoqo ejikelezayo yemoto, eyenza i-torque ejikelezayo ngokusebenzisana ne-stator magnetic field ukuze uqhube umthwalo emsebenzini. Iinzuzo eziphambili zisebenza ngokuzinzile kunye nokuqina. Ngokomzekelo, kwi-motor yempompo enkulu yoshishino, ukujikeleza kwe-rotor kuqhuba i-shaft yepompo, evumela ukuba ulwelo luhanjiswe. I-rotor ijikeleza kwi-sliding bear, enika inkxaso kwi-rotor kwaye ithwala i-radial kunye ne-axial forces ye-rotor. Xa isantya se-rotor kunye nomthwalo ungaphakathi koluhlu oluchaziweyo, i-rotor ijikeleza ngokufanelekileyo kwi-bearing, enokunciphisa ukungcangcazela kunye nengxolo. Ngokomzekelo, kwezinye iinkqubo zemveliso yemizi-mveliso ezifuna uzinzo oluphezulu lokusebenza, ezifana nephepha, iingubo kunye namanye amashishini, ii-motor sliding bearing inokuqinisekisa ukuqhubeka kwemveliso kunye nomgangatho wemveliso.
4. Isishwankathelo
Ukusetyenziswa kunye nophuhliso lwee-rotor ze-motor-speed-speed ziye zazisa amathuba kunye notshintsho kumashishini amaninzi. Nokuba ziinjini ezithwele imagnethi, iimotor ezithwele umoya okanye iimotor ezityibilikayo, zonke zidlala indima ephambili kumacandelo azo esicelo kwaye zisombulule iingxaki ezininzi ezijongene neemoto zemveli.
