Eminyakeni yamuva nje, izinjini eziqondile ezisebenza ngozibuthe zenze inqubekelaphambili enkulu futhi zisetshenziswa kakhulu emithwalweni enejubane eliphansi, njengezithutha amabhande, izixube, imishini yokudweba izintambo, amaphampu anejubane eliphansi, ashintsha amasistimu kagesi akhiwe amamotho anesivinini esikhulu kanye nemishini. izindlela zokunciphisa.Ijubane lenjini ngokuvamile lingaphansi kuka-500rpm.I-Permanent magnet direct drive motors ingahlukaniswa ngokuyinhloko ibe yizinhlobo ezimbili zesakhiwo: i-rotor yangaphandle ne-rotor yangaphakathi.I-rotor yangaphandle unomphela ozibuthe drive eqondile isetshenziswa ikakhulukazi kuma-conveyors amabhande.
Ekwakheni nasekusetshenzisweni kwezinjini eziqondile zikazibuthe eziqondile, kufanele kuqashelwe ukuthi idrayivu eqondile kazibuthe ehlala njalo ayifanele isivinini esiphansi sokuphumayo.Lapho iningi lilayisha ngaphakathi5I-0r / min iqhutshwa yi-motor drive eqondile, uma amandla ehlala ehlala njalo, kuzoholela ku-torque enkulu, okuholela ezindlekweni eziphezulu zemoto kanye nokunciphisa ukusebenza kahle.Lapho amandla nesivinini kunqunywa, kuyadingeka ukuqhathanisa ukusebenza kahle kwezomnotho kwenhlanganisela yama-motor aqondile, ama-motor esivinini esikhulu, namagiya (noma esinye isivinini esikhuphukayo kanye nokuncipha kwezakhiwo zemishini).Njengamanje, izinjini zomoya ezingaphezu kuka-15MW nangaphansi kuka-10rpm kancane kancane zamukela uhlelo lokushayela i-semi direct drive, zisebenzisa amagiya ukukhulisa isivinini semoto ngendlela efanele, ukunciphisa izindleko zezimoto, futhi ekugcineni zehlise izindleko zesistimu.Okufanayo kusebenza kuma-motor kagesi.Ngakho-ke, lapho ijubane lingaphansi kuka-100 r/min, ukucatshangelwa kwezomnotho kufanele kucatshangelwe ngokucophelela, futhi uhlelo lwe-semi direct drive lungakhethwa.
Izinjini eziqondile zikazibuthe ezihlala njalo ngokuvamile zisebenzisa amarotha kazibuthe angaphezulu afakwe phezulu ukuze akhulise ukuminyana kwetorque futhi anciphise ukusetshenziswa kwezinto.Ngenxa yejubane eliphansi lokujikeleza namandla amancane e-centrifugal, akudingekile ukusebenzisa ukwakheka kwerotha kazibuthe eyakhelwe ngaphakathi unomphela.Ngokuvamile, imigoqo yokucindezela, imikhono yensimbi engagqwali, nemikhono evikelayo ye-fiberglass isetshenziselwa ukulungisa nokuvikela uzibuthe we-rotor unomphela.Kodwa-ke, amanye amamotho anezidingo ezithembeke kakhulu, izinombolo zezigxobo ezincane, noma ukudlidliza okuphezulu zisebenzisa izakhiwo zerotor kazibuthe ezakhelwe ngaphakathi.
I-low-speed direct drive motor ishayelwa i-frequency converter.Lapho idizayini yenombolo yesigxobo ifinyelela umkhawulo ophezulu, ukuncipha okwengeziwe kwejubane kuzoholela emazingeni aphansi.Uma imvamisa yesiguquli semvamisa iphansi, umjikelezo wemisebenzi we-PWM uyancipha, futhi i-waveform impofu, okungaholela ekushintshashintsheni kanye nesivinini esingazinzile.Ngakho-ke ukulawulwa kwama-motor okushayela aqondile aphansi kakhulu nakho kunzima kakhulu.Njengamanje, amanye amamotho anesivinini esiphansi kakhulu asebenzisa isikimu semoto kazibuthe ukuze asebenzise imvamisa yokushayela ephezulu.
Isivinini esiphansi esihlala unomphela ozibuthe we-Direct drive motors singaba ngokupholisa umoya futhi apholiswe uketshezi.Ukupholisa komoya ikakhulukazi kusebenzisa indlela yokupholisa ye-IC416 yabalandeli abazimele, futhi ukupholisa uketshezi kungaba ukupholisa amanzi (IC71W), enganqunywa ngokuya ngemibandela yendawo.Kumodi yokupholisa okuwuketshezi, umthwalo wokushisa ungaklanywa ube phezulu futhi isakhiwo siminyene kakhudlwana, kodwa kufanele kuqashelwe ekwandiseni ukushuba kazibuthe unomphela ukuvimbela ukuwohloka kozibuthe okudlulele.
Kumasistimu emoto ahamba ngesivinini esiphansi anezidingo zokulawula ukunemba kwesivinini kanye nesikhundla, kuyadingeka ukwengeza izinzwa zesikhundla futhi wamukele indlela yokulawula enezinzwa zokuma;Ukwengeza, uma kunesidingo se-torque ephezulu ngesikhathi sokuqalisa, indlela yokulawula enenzwa yendawo nayo iyadingeka.
Nakuba ukusetshenziswa kwezinjini eziqondile zikazibuthe eziqondile kungaqeda indlela yokwehliswa kwasekuqaleni futhi kunciphise izindleko zokuyilungisa, umklamo ongenangqondo ungaholela ezindlekweni eziphakeme zama-motor unomphela ozibuthe oqondile kanye nokwehla kokusebenza kahle kohlelo.Ngokuvamile, ukukhulisa ububanzi bezinjini eziqondile ezisebenza ngozibuthe kunganciphisa izindleko nge-torque ngayinye yeyunithi, ngakho-ke ama-motor drive angenziwa abe idiski enkulu enobubanzi obukhudlwana kanye nobude besitaki obufushane.Nokho, kukhona futhi imingcele ukwanda ububanzi.I-diameter enkulu ngokweqile ingakhuphula izindleko ze-casing kanye ne-shaft, futhi ngisho nezinto zokwakha zizodlula kancane kancane izindleko zezinto ezisebenzayo.Ngakho-ke ukuklama injini yokushayela eqondile kudinga ukukhulisa isilinganiso sobude nobubanzi ukuze kwehliswe izindleko zizonke zemoto.
Okokugcina, ngithanda ukugcizelela ukuthi izinjini eziqondile ezisebenza ngozibuthe zisengamamotho aqhutshwa yi-frequency converter.Isici samandla se-motor sithinta okwamanje ohlangothini oluphumayo lwesiguquli sefrikhwensi.Uma nje ingaphakathi kwebanga lomthamo wesiguquli sefrikhwensi, isici samandla sinomthelela omncane ekusebenzeni futhi ngeke sithinte isici samandla ohlangothini lwegridi.Ngakho-ke, umklamo wesici samandla wemoto kufanele ulwele ukuqinisekisa ukuthi idrayivu eqondile isebenza kumodi ye-MTPA, ekhiqiza i-torque ephezulu ngobuncane bamanje.Isizathu esibalulekile ukuthi imvamisa ye-Direct drive motors ngokuvamile iphansi, futhi ukulahlekelwa kwensimbi kuphansi kakhulu kunokulahlekelwa kwethusi.Ukusebenzisa indlela ye-MTPA kunganciphisa ukulahleka kwethusi.Ochwepheshe akufanele bathonywe igridi yendabuko exhunywe ama-asynchronous motors, futhi asikho isisekelo sokwahlulela ukusebenza kahle kwenjini ngokusekelwe kubukhulu bamanje ohlangothini lwemoto.
I-Anhui Mingteng Permanent-Magnetic Machinery &Electrical Equipment Co., Ltd iyibhizinisi lesimanje lobuchwepheshe obuphezulu elihlanganisa ucwaningo nentuthuko, ukukhiqiza, ukuthengisa, kanye nensizakalo yamamotho kazibuthe ahlala unomphela.Izinhlobonhlobo zomkhiqizo kanye nokucaciswa kuphelele.Phakathi kwazo, amamotho kazibuthe ahamba ngesivinini esiphansi (7.5-500rpm) asetshenziswa kakhulu kumthwalo wezimboni njengabalandeli, amabhande okuthutha amabhande, amaphampu ama-plunger, nezigayo zikasimende, izinto zokwakha, ezimayini zamalahle, i-petroleum, i-metallurgy, nezinye izimboni. , enezimo zokusebenza ezinhle.
