Nge-14 kaDisemba, 2021, yintoni umahluko phakathiinjini yokufaka umoyakunye nemoto eqhelekileyo?
(1) Iinkqubo zoyilo ezahlukeneyo:
1. Inkqubo yokutshatyalaliswa kobushushu iyahluka: i-fan yokutshatyalaliswa kobushushu kwi-fan eqhelekileyo kunye nengundoqo ye-centrifugal fan isebenzisa umgca ofanayo, ngelixa ezimbini kwi-motor ventilation ziyahlukana.Ke ngoko, xa ukuguqulwa kwamatyeli kwefeni eqhelekileyo kuphantsi kakhulu, kuya kutshiswa ngenxa yobushushu obugqithisileyo.
2. Uyilo lwe-electromagnetic lwahlukile: kwiimotor eziqhelekileyo, iiparameters eziphambili zobugcisa eziqwalaselwa kwiskimu sokuyila ngokutsha ngumthamo ogqithisiweyo, iimpawu zokusebenza, ukusebenza kakuhle kunye nezinto zamandla.I-motor ye-ventilation, ngenxa yokuba isantya esibalulekileyo se-slip sichaneke ngokungafaniyo kunye nomthamo wamandla, sinokuqalwa ngokuthe ngqo xa isantya esibalulekileyo se-slip sifikelela kwi-1. Ngoko ke, umthamo womthwalo kunye neempawu zokusebenza akufanele zicatshangelwe kakhulu.Ingxaki emayisonjululwe yindlela yokuphucula ukuziqhelanisa nemoto kunikezelo lwamandla olungelulo lwe-sine wave.
3. Ngenxa yokuba i-motor ye-ventilation ine-high-frequency electromagnetic field, ibakala lokubuyiswa komlilo liphezulu kunelo lemoto eqhelekileyo.Ngokomgaqo, i-motor eqhelekileyo ayinakuqhutywa yi-converter frequency, kodwa eneneni, ukuze kugcinwe i-asethi, i-motor eqhelekileyo isetyenziselwa ukutshintsha i-motor-frequency motor kwiindawo ezininzi apho utshintsho lwesantya luyimfuneko, kodwa utshintsho lwesantya oluchanekileyo lwemoto eqhelekileyo. ayikho phezulu.Kwifeni ye-centrifugal Oku kuyenziwa rhoqo ekuguquleni ukonga amandla kwimpompo yamanzi eyi-centrifugal.
4. Umthwalo owandisiweyo we-electromagnetic: ukuchasana kwemveliso yemoto eqhelekileyo kusekelwe kwindawo yokuguquguquka kwemagnethi.Ukuba isetyenziswe njengenguquko yefrikhwensi, kulula ukuhluthwa, okukhokelela kwi-excitation yangoku.Ngelixa i-motor ye-ventilation yandisa umthwalo we-electromagnetic kwisikimu soyilo, ukuze isekethe yamagnetic ingabi lula ukugcwala.Enye yeyokuba iimoto eziguquguqukayo ezijikelezayo zihlala zohlulwa zibe ziimotor ezikhethekileyo zetorque, iimotor ezikhethekileyo ezinezixhobo zokunciphisa isantya kunye neemotor frequency eziphakathi ezinolawulo lwevector yengxelo.
(2) Umahluko kumlinganiselo:
1. Enyanisweni, i-wave waveform ye-frequency converter yi-sinusoidal wave.Ukongeza kwi-wave yesiseko, ikwabandakanya isignali yomthwali.Umthamo wedatha yomthwali wedatha uphezulu kakhulu kuneliza elisisiseko, kwaye sisiginali yedatha yesikweri, kubandakanya iiharmonics zomyalelo ophezulu.Kwisistim yokufumanisa, iisampulu ephezulu rhoqo kunye ne-bandwidth yenethiwekhi ichaziwe.
2. Kwimeko-bume yenkqubo yonikezelo lwamandla ombane oguquguqukayo, zonke iintlobo zophazamiseko oluphezulu zikho kuyo yonke indawo, kwaye umqondiso wophazamiseko womelele kakhulu kunalowo ukwimo engqongileyo yamandla, echaza ukuba inkqubo yobhaqo inamandla obuchule obuchwephesha bokuhambelana kwe-electromagnetic.
3. I-peak factor ye-drive circuit wave wave idla ngokuba phezulu.Izibonelelo ziqwalaselwa ngokohlobo lwezixhobo eziqhelekileyo.Kwisixokelelwano soguqulo loguqulo oluphindaphindiweyo, kuyafuneka ukuba ube nesakhono somlinganiselo ochanekileyo ophezulu wento ephezulu.
