Umphakeli wemishini esekela i-frequency converter ukukhumbuza ukuthi imvamisa, idivayisi eguqula i-voltage engaguquki kanye namandla e-AC emvamisa ibe yi-voltage eguquguqukayo noma amandla e-AC efrikhwensi ibizwa ngokuthi "i-frequency converter". Phakathi kobuchwepheshe obuhlukahlukene bokulawula isivinini sezimoto, ukulawulwa kwesivinini esishintshashintshayo samamotho e-AC sekuyindlela eyinhloko yokudlulisa ugesi ngenxa yezinzuzo zako njengokunemba okuphezulu, i-torque enkulu, ukusebenza okuqinile, ukwethembeka okuphezulu, namandla aphezulu.
Ngenxa yomsebenzi wokuqhubeka nokulungisa ijubane lama-asynchronous motors ane-torque namandla angaguquki, iziguquli zemvamisa zinebanga elikhulu lejubane lokulungisa, ukuzinza okuphezulu, nezici eziqinile zemishini. Isici esibucayi kakhulu umphumela wabo osobala wokonga amandla, osiza ukusheshisa inqubo yokukhiqiza okuzenzakalelayo kwezimboni nezinye izici eziningi. Lokhu kuye kwanweba kancane kancane ububanzi bokusetshenziswa kweziguquli zefrikhwensi, ngokuvamile okubandakanya yonke imikhakha, njengokukhiqiza ezimbonini ezilula nezisindayo kanye nempilo yansuku zonke yabantu.

Ukusetshenziswa kwe-frequency converter emishinini yezimboni kanye nemithwalo yephampu yemishini
Isizathu sokuthi kungani ama-frequency converter angasetshenziswa kabanzi emishinini yezimboni kanye nemithwalo yephampu yemishini kungenxa yobuchwepheshe babo obunamandla bokulawula isivinini, obusebenzisa imvamisa ye-stator yemoto ukushintsha ijubane lemoto ngokufanele, ekugcineni kuguqule izimo zokusebenza zemithwalo yephampu nokwenza imishini yasekuqaleni ikwazi ukuhlangabezana nezidingo zokukhiqiza. Uma kukhona ushintsho olukhulu emthwalweni wemishini eyimishini namaphampu ekukhiqizeni kwezimboni, kusetshenziswa ubuchwepheshe bokuguqula imvamisa ukulawula ukuphuma kwesiguquli semvamisa kungenza umthwalo wephampu uhlangabezane nezimo zenqubo yokukhiqiza, uzuze umphumela ongcono kakhulu wokonga amandla, uthuthukise izinga lokukhiqiza, usheshise inqubo yokushintshashintsha kwezimboni, futhi andise impilo yesevisi yemishini, uthuthukise ikhwalithi yomkhiqizo, ukhuphule ukusebenza kahle kokukhiqiza, futhi uvumele amabhizinisi ukuthi athole izinzuzo eziphezulu zomnotho.
Ukusetshenziswa kwe-frequency converter kumthwalo wabalandeli bemishini yokukhiqiza yezimboni
Amafeni asetshenziswa ngokuyisisekelo ezinhlelweni zokupholisa, kumasistimu amaboyili, amasistimu okomisa, nezinhlelo zokukhipha umoya ekukhiqizeni izimboni. Enqubweni yokukhiqiza, sizolawula izici ezifana nevolumu yomoya nezinga lokushisa elithinta ukukhiqizwa ukuze sifinyelele izimo ezinhle zobuchwepheshe bokukhiqiza nezimo zokusebenza. Enqubweni yokulawula yangaphambilini, indlela evame ukusetshenziswa kwakuwukulungisa izinga lokuvula nokuvala le-outlet kanye ne-baffle. Ububi bokusebenzisa le ndlela yokulawula ukuthi kungakhathaliseki ukuthi iyiphi inqubo yokukhiqiza nezimo zokusebenza, umlandeli uhlala egijima ngesivinini esingaguquki, esingakwazi ukuhlangabezana ngokunembile nezimo zenqubo yokukhiqiza nezimo zokusebenza, uchitha amandla futhi udle imishini nezinto zokwakha, unciphisa inzuzo yokukhiqiza, futhi unciphisa impilo yesevisi yemishini. Isibonelo, izitshalo zefiber zamakhemikhali, izitshalo zensimbi, izitshalo zikasimende, njll. zonke zisebenzisa amafeni. Uma sisebenzisa ukulungisa indawo yokukhipha umoya ukuze sishintshe ivolumu yomoya, injini izohlala isebenza ngomthwalo ogcwele, kodwa ukuvulwa kwe-damper yomoya kuphakathi kuka-50% no-80% kuphela, okungaba ukuziphatha okumoshayo. Ubuchwepheshe bokuguqula imvamisa busetshenziswa emthwalweni wefeni, futhi ukusebenza kwawo kokulawula isivinini esingenasinyathelo kunganweba ibanga lejubane le-fan, kukwenze kuthembeke kakhudlwana, kube lula ukuhlela, nokufeza izimo eziphakeme zezinqubo zokukhiqiza nezimo zokusebenza.
Ukusetshenziswa kweziguquli zemvamisa ekongiweni kwamandla nasekunciphiseni ukusetshenziswa
Ezindaweni lapho umthwalo wemoto ngokuvamile ungaguquki, njengezigayo zendwangu kanye nezigayo zensimbi, injini ivamise ukusebenza ngamandla athile, futhi ukusebenza kwesiguquli semvamisa kunzima ukukushintshwa ngezinye izinto zokusebenza, njengokusheshisa okushelelayo nokwehla kwejubane, itorque yokulawula enembile, nokuzinza okuhle kokusebenza, ukuze isetshenziswe kahle. Emafekthri anjalo, abaguquli bemvamisa abahluleki nje ukugcina amandla, kodwa ngokuphambene nalokho, ngenxa yezindleko zabo eziphakeme kanye nokusetshenziswa kwamandla, lonke uhlelo lubiza kakhulu futhi ludla amandla amaningi. Ngokuphambene nalokho, ezinhlelweni ezifana namafeni namaphampu, izici zokonga amandla nokunciphisa ukusetshenziswa ziba zivelele kakhulu. Kulezi zinhlelo zokusebenza, umthwalo wamanje uvame ukushintsha. Uma ama-motor amaningana esetshenziswa ngokufana, nakanjani azokwandisa izindleko zemishini. Uma indlela yokulawula isivinini yangaphambilini isetshenziswa, futhi ayihambisani nokufeza umgomo wokuzenzakalela kokukhiqiza. Kulokhu, abanye abakhiqizi bakhiqize iziguquli zefrikhwensi ezikhethekile zalolu hlelo lokusebenza. Lolu hlobo lwesiguquli semvamisa alunazo izici zokulawulwa kwejubane lokunemba okuphezulu nokulawulwa kwe-torque, ngakho-ke izindleko zalo zokukhiqiza nazo ziphansi kakhulu.
