NgoDisemba 14, 2021, yini umehluko phakathii-ventilation motorkanye nemoto evamile?
(1) Amasistimu wokuklama ahlukene:
1. Isistimu yokukhipha ukushisa ihlukile: ifeni yokukhipha ukushisa kufeni evamile kanye nomnyombo wefeni ye-centrifugal isebenzisa umugqa ofanayo, kuyilapho okubili kumotho wokungenisa umoya kuhlukanisiwe.Ngakho-ke, lapho ukuguqulwa kwemvamisa kwefeni evamile kuphansi kakhulu, izoshiswa ngenxa yezinga lokushisa elingaphezulu.
2. Idizayini ye-electromagnetic ihlukile: kumamotho ajwayelekile, amapharamitha obuchwepheshe abalulekile acatshangelwa esikimini sokuklama kabusha umthamo wokulayisha ngokweqile, izici zokusebenza, ukusebenza kahle okuphezulu nezici zamandla.I-motor ye-ventilation, ngenxa yokuthi izinga lokushelela elibucayi liphikisana ngokuphambene nemvamisa yamandla, lingaqalwa ngokuqondile lapho izinga lokushelela elibucayi lifinyelela ku-1. Ngakho-ke, umthamo womthwalo kanye nezici zokusebenza akufanele zicatshangelwe kakhulu.Inkinga okufanele ixazululwe ukuthi ungathuthukisa kanjani ukuguquguquka kwemoto kugesi we-non sine wave.
3. Ngenxa yokuthi injini yokungenisa umoya ithwala inkambu ye-electromagnetic high-frequency, ibanga elibuyisela amalangabi liphakeme kunelenjini evamile.Eqinisweni, i-motor evamile ayikwazi ukuqhutshwa yi-converter ye-frequency, kodwa empeleni, ukuze kugcinwe impahla, i-motor evamile isetshenziselwa ukufaka esikhundleni se-variable-frequency motor ezindaweni eziningi lapho kudingeka khona ukuguqulwa kwesivinini, kodwa ukunemba kokuguqulwa kwesivinini semoto evamile. ayiphezulu.Kufeni ye-centrifugal Lokhu kuvame ukwenziwa ekuguquleni ukonga amandla wephampu yamanzi eyi-centrifugal.
4. Umthwalo we-electromagnetic owandisiwe: ukumelana okukhiphayo kwemoto evamile kusekelwe endaweni yokuguquguquka kokugcwaliswa kazibuthe.Uma isetshenziswa njengokuguqulwa kwemvamisa, kulula ukugcwala, okuholela ekuvuseni okuphezulu kwamanje.Ngenkathi i-ventilation motor inweba umthwalo we-electromagnetic ohlelweni lokuklama, ukuze umjikelezo kazibuthe ungabi lula ukugcwala.Okunye ukuthi ama-motor frequency aguquguqukayo avame ukuhlukaniswa abe ama-motor akhethekile e-torque, ama-motor akhethekile anemishini yokunciphisa isivinini kanye nama-medium frequency motors anokulawulwa kwe-vector yempendulo.
(2) Umehluko esilinganisweni:
1. Eqinisweni, i-waveform ephumayo yesiguquli se-frequency i-sinusoidal wave.Ngokungeziwe kumagagasi ayisisekelo, kuhlanganisa nesignali yenkampani yenethiwekhi.Imvamisa yesignali yedatha yenkampani yenethiwekhi iphakeme kakhulu kunegagasi eliyisisekelo, futhi iyisiginali yedatha yegagasi eliyisikwele, okuhlanganisa nama-harmonics amaningi e-oda eliphezulu.Ohlelweni lokuhlonza, imvamisa ephezulu yesampula kanye nomkhawulokudonsa wenethiwekhi kuyacaciswa.
2. Endaweni yesistimu yokunikeza amandla esiguquli semvamisa, zonke izinhlobo zokuphazamiseka kwemvamisa ephezulu zikuyo yonke indawo, futhi isignali yokuphazamisa inamandla kakhulu kunaleyo esendaweni yefrikhwensi yamandla, ebeka ukuthi isistimu yokuthola inekhono eliqinile lobuchwephesha lokuhambisana kwe-electromagnetic.
3. Isici esiphezulu segagasi lesifunda sokushayela ngokuvamile siphezulu.Imibandela ibhekwa ngohlobo lwamathuluzi ajwayelekile.Kusistimu yokuthola ukuguqulwa kwemvamisa, kuyadingeka ukuthi ube namandla aphezulu wokulinganisa anembe we-peak factor.
