Abaguquli bemvamisa: Ukuthuthukisa ukusebenza kahle kwamandla kanye nokusebenza kahle kwawo
A isiguquli semvamisa, eyaziwa nangokuthi i-variableidrayivu yemvamisa (VFD), iyithuluzi elilawula ijubane lenjini ngokulawula imvamisa kanye ne-voltage enikezwa yinjini. Lobu buchwepheshe budumile kuzo zonke izimboni ngenxa yekhono lalo lokuthuthukisa kakhulu ukusebenza kahle kwamandla nokuthuthukisa ukusebenza kwenjini.
Enye yezinzuzo eziyinhloko zokusebenzisa i-isiguquli semvamisayikhono layo lokulawula ijubane lemoto ngokuya ngomthwalo odingekayo. Amamotha avamile asebenza ngesivinini esingaguquki kungakhathaliseki ukuthi umthwalo udinga malini, okuholela ekusetshenzisweni kwamandla okungadingekile. Kodwa-ke, ngokusebenzisa i-frequency converter, ijubane lemoto lingalungiswa ngokunembile ukuze lifane nomthwalo odingekayo, okwenza kube ngcono ukusebenza kahle kwamandla. Lokhu kuzuzisa kakhulu ekusetshenzisweni okunesidingo somthwalo esishintshashintshayo, okuvumela amazinga aphezulu okonga amandla kanye nezindleko zokusebenza eziphansi.
Ngaphezu kokusebenzisa kahle amandla,abaguquli bemvamisainikeza izici ezahlukahlukene zokuthuthukisa ukusebenza. Ngokulawula ijubane lemoto, ukucindezeleka komshini kanye nokuguguleka kwemoto kanye nemishini exhunyiwe kungancishiswa. Lokhu kwandisa impilo yenkonzo yomshini, ngaleyo ndlela kunciphisa izindleko zokulungisa nokufaka esikhundleni. Ngaphezu kwalokho, ikhono lokulungisa ijubane lemoto landisa ukulawula nokunemba, okuholela emiphumeleni yenqubo enembile nehambisanayo.
Ngaphezu kwalokho, ama-frequency converters asiza ekunikezeni ukulawula okungcono kokuqala nokumisa imisebenzi. Ngokungafani nabaqalisi abaqondile ku-inthanethi,abaguquli bemvamisainikeza ukuqala okubushelelezi, kancane kancane, kunciphisa ukukhuphuka okungazelelwe kanye nokucindezeleka komshini enjinini. Ukuqala okuthambile akugcini nje ngokunciphisa ukuguguleka, kodwa futhi kunikeza ukulawula okukhulu kanye nokuvikelwa eziqongweni ze-torque. Amandla okulawula ukusheshisa kwenjini kanye nokwehla kwejubane futhi kwenza kube nokwenzeka ukubeka kahle izinhlelo zokusebenza ezifana namarobhothi kanye nama-conveyor, okuthuthukisa ukukhiqiza kanye nekhwalithi.
Njengoba ubuchwepheshe buthuthuka, abaguquli bemvamisa banamuhla bahlonyiswe ngezici ezengeziwe ezifana nokuxilonga okwakhelwe ngaphakathi, abalawuli be-logic abahlelekayo (ama-PLC), kanye nezixhumi zokuqapha nokulawula kude. Lezi zici zivumela ukuhlanganiswa okungenamthungo nezinhlelo zokwenza izinto ngokuzenzakalela, okuthuthukisa ukuguquguquka kokusebenza kanye nokulula kokusetshenziswa.
Ngokufigqiwe,abaguquli bemvamisazidlala indima ebalulekile ekwenzeni ngcono ukusebenza kahle kwamandla kanye nokuthuthukisa ukusebenza kwezimoto. Ngokulawula ngokunembile isivinini sezimoto, zonga amandla, zinciphise izindleko zokulungisa, futhi zinikeze ukulawula nokuvikela okungcono. Njengoba ubuchwepheshe buqhubeka nokukhula,abaguquli bemvamisaizoqhubeka nokuba yingxenye ebalulekile yezimboni ezilwela ukuthuthukisa ukusebenza kahle kanye nokukhiqiza.
