Umjikelo wentsebenzo jikelele we-axial flow fan ibonisiwe kumzobo:
I-curve ye-pressure ine-hump, njengendawo yokusebenza kwindawo efanelekileyo ye-hump, i-fan work state izinzileyo;Ukuba indawo yokusebenza ikwindawo ekhohlo ye-hump, imeko yokusebenza yefeni kunzima ukuzinza.Ngeli xesha, uxinzelelo lomoya kunye nokuhamba kuyaguquguquka.Xa indawo yokusebenza isiya ezantsi ekhohlo, ukuqukuqela kunye noxinzelelo lomoya lunokubetha ngamandla, kwaye kubangele ukuba ifeni yonke inyuke.Iyunithi yefeni inokonakala ngokutyanda, ngoko ke ifeni ayivumelekanga ukuba isebenze phantsi kwemeko yotyando.Ukuze ugweme isiganeko sokunyuka kwe-fan kwisantya esincinci sokuhamba, ukuguqulwa kwenguqu ye-frequency ye-fan yinto yokuqala, kwaye xa utshintsho lwesantya se-fan lungagqithisi i-20%, ukusebenza kakuhle akutshintshi, ukusetyenziswa kwe-frequency. ukulawulwa kwesantya sokuguqulwa kunokwenza i-fan isebenze kwicandelo elincinci lokuhamba okusebenzayo, ayizukwenza nje i-fan surge, kodwa yandise ukusebenza okusebenzayo koluhlu lwabalandeli.
I-ventilator ephambili isetyenziswa ngokuphindaphindiweyo kwamandla, kwaye umthamo wokungenisa umoya ulungelelaniswa ngokubanzi ngokutshintsha i-Angle ye-vane yesikhokelo kunye ne-baffle plate ngexesha lokusebenza.Ngoko ke, ukusebenza kakuhle kokungena komoya kuphantsi, okukhokelela kwinkcitho yamandla kunye nokunyusa ixabiso lemveliso.Ukongeza, ngenxa yomda woyilo omkhulu we-ventilator ephambili, i-ventilator ephambili ibisebenza phantsi komthwalo okhanyayo ixesha elide, kwaye inkunkuma yamandla ibalasele.
Xa umqhubi oyintloko usebenzisa i-reactance ukuqalisa, ixesha lokuqalisa lide kwaye isiqalo sangoku sikhulu, esisoyikiso esikhulu kwi-insulation ye-motor, kwaye ide itshise i-motor kwiimeko ezinzulu.Isenzeko se-uniaxial torque yemoto ephezulu yombane kwinkqubo yokuqala yenza ukuba ifeni ivelise uxinzelelo olukhulu lokungcangcazela, oluchaphazela kakhulu ubomi benkonzo yemoto, fan kunye nabanye oomatshini.
Ukuqwalasela ezi zizathu zingasentla, kungcono ukusebenzisarhoqoguqularukulungelelanisa umthamo womoya we-ventilator engundoqo.
Amandla ombane aphezulurhoqoumguquli eveliswe nguNoker Electric ithatha isantya esiphezulu se-DSP njengeyona nto iphambili yokulawula, ithatha itekhnoloji yokulawula i-velocity velocity kunye nothotho lwe-multilevel technology yeyunithi yamandla.Yeyokuguqulela okuphakamileyo komthombo wamandla ombane aphezulu, isalathiso sayo se-harmonic singaphantsi kwe-IEE519-1992 yomgangatho wesizwe we-harmonic, kunye nomgangatho ophezulu wokufaka amandla kunye nomgangatho olungileyo we-waveform.Akukho mfuneko yokusebenzisa igalelo lokucoca i-harmonic, isixhobo sembuyekezo yesixhobo samandla kunye nesihluzo semveliso;Akukho harmonic ebangelwa kukufudumala okongeziweyo kwemoto kunye ne-torque ripple, ingxolo, i-dv / dt ephumayo, i-voltage yemowudi eqhelekileyo kunye nezinye iingxaki, ungasebenzisa i-motor ye-asynchronous eqhelekileyo.
Ngokwemeko yokwenyani yesiza somsebenzisi, ikhabhinethi yokudlula yamkele iskimu setrektara enye uguqulelo oluzenzekelayo lomqhubi.Njengoko kuboniswe kumfanekiso ongezantsi.Kwikhabhinethi edlulayo, kukho izitshixo ezimbini zokwahlula amandla ombane aphezulu kunye nezimbini zonxibelelwano lwevacuum.Ukuqinisekisa ukuba akukho mandla athunyelwa emva ekupheleni kwemveliso yokuguqula, i-KM3 kunye ne-KM4 zidibene ngombane.Xa i-K1, i-K3, i-KM1 kunye ne-KM3 zivaliwe kwaye i-KM4 inqanyuliwe, i-motor iqhuba ngokuguqulwa kwamaza;Xa i-KM1 kunye ne-KM3 zinqanyuliwe kwaye i-KM4 ivaliwe, i-frequency power frequency ye-motor ibaleka.Ngeli xesha, i-converter frequency ihlukanisiwe kumbane ophezulu, olungele ukulungiswa, ukugcinwa kunye nokulungiswa.
Ikhabhinethi ye-bypass kufuneka idityaniswe kunye ne-DL ye-high voltage breaker circuit.Xa i-DL ivaliwe, musa ukusebenzisa i-inverter output isolation switch ukukhusela i-arc-pulling kwaye uqinisekise ukhuseleko lwabaqhubi kunye nezixhobo.
IIsantya sombane esiPhakathi esiguquguqukayoIidrives ibisebenza ngokuzinzileyo ukusukela oko yaqala ukusebenza, i-frequency ephumayo, i-voltage kunye neyangoku izinzile, i-fan ibaleka ngokuzinzileyo, umlinganiselo wamandla wecala lenethiwekhi ye-frequency converter yi-0.976, ukusebenza kakuhle kungaphezulu kwe-96%, umthamo opheleleyo wecala lomnatha i-harmonic yangoku ingaphantsi kwe-3%, kwaye imveliso ye-harmonic yangoku ingaphantsi kwe-4% xa umthwalo ogcweleyo.I-fan iqhuba ngesantya esisezantsi kunesantya esilinganisiweyo, esingagcini nje kuphela amandla, sinciphisa iindleko zokugcinwa, kodwa sinciphisa ingxolo yomqhubi, kwaye sifumana umphumo omhle wokusebenza kunye nenzuzo yezoqoqosho.
