Iyunithi yesihlungi se-FFU fan iyithuluzi elidingekayo kumaphrojekthi egumbi elihlanzekile. Futhi iyiyunithi yesihlungi somoya esibalulekile ekamelweni elihlanzekile elingenalo uthuli. Iyadingeka futhi emabhentshini okusebenzela ahlanzekile kakhulu kanye ne-booth ehlanzekile.
Ngokuthuthuka komnotho kanye nokuthuthukiswa kwezinga lokuphila labantu, abantu banezidingo eziphakeme kakhulu zekhwalithi yomkhiqizo. I-FFU inquma ikhwalithi yomkhiqizo ngokusekelwe kubuchwepheshe bokukhiqiza kanye nendawo yokukhiqiza, okuphoqa abakhiqizi ukuthi baphishekele ubuchwepheshe bokukhiqiza obungcono.
Amasimu asebenzisa amayunithi okuhlunga abalandeli be-FFU, ikakhulukazi i-elekthronikhi, imithi, ukudla, i-bioengineering, ezokwelapha, kanye nama-laboratory, anezidingo eziqinile zendawo yokukhiqiza. Ihlanganisa ubuchwepheshe, ukwakhiwa, ukuhlobisa, ukuhlinzekwa kwamanzi kanye nokugeleza kwamanzi, ukuhlanzwa komoya, i-HVAC kanye ne-air conditioning, ukulawula okuzenzakalelayo kanye nobunye ubuchwepheshe obuhlukahlukene. Izinkomba zobuchwepheshe eziyinhloko zokulinganisa ikhwalithi yendawo yokukhiqiza kulezi zimboni zifaka phakathi izinga lokushisa, umswakama, ukuhlanzeka, umthamo womoya, ingcindezi yangaphakathi, njll.
Ngakho-ke, ukulawulwa okunengqondo kwezinkomba zobuchwepheshe ezahlukahlukene zendawo yokukhiqiza ukuze kuhlangatshezwane nezidingo zezinqubo zokukhiqiza ezikhethekile sekungenye yezindawo ezidumile zocwaningo lwamanje kwezobunjiniyela begumbi elihlanzekile. Ngasekuqaleni kwawo-1960, kwasungulwa igumbi lokuqala elihlanzekile emhlabeni elinomoya ophansi. Ukusetshenziswa kwe-FFU sekuqalile ukuvela selokhu yasungulwa.
1. Isimo samanje sendlela yokulawula i-FFU
Njengamanje, i-FFU ngokuvamile isebenzisa ama-motor e-AC anesivinini esikhulu sesigaba esisodwa, ama-motor e-EC anesivinini esikhulu sesigaba esisodwa. Kukhona cishe ama-voltage amabili okunikezwa kwamandla emoto yeyunithi yesihlungi sabalandeli be-FFU: 110V kanye no-220V.
Izindlela zayo zokulawula zihlukaniswe kakhulu ngezigaba ezilandelayo:
(1). Ukulawula ukushintshashintsha okunesivinini esiningi
(2). Ukulawula ukulungiswa kwesivinini okungenazinyathelo
(3). Ukulawulwa kwekhompyutha
(4). Ukulawula kude
Okulandelayo ukuhlaziywa okulula kanye nokuqhathanisa izindlela zokulawula ezine ezingenhla:
2. Ukulawula ukushintshashintsha kwe-FFU okunesivinini esiningi
Uhlelo lokulawula ukushintshashintsha ngesivinini esiningi luhlanganisa kuphela ukushintshashintsha kokulawula isivinini kanye nokushintsha kwamandla okuhambisana ne-FFU. Njengoba izingxenye zokulawula zinikezwa yi-FFU futhi zisatshalaliswa ezindaweni ezahlukene ophahleni lwegumbi elihlanzekile, abasebenzi kumele balungise i-FFU ngokusebenzisa ukushintshashintsha okusendaweni, okuyinto enzima kakhulu ukuyilawula. Ngaphezu kwalokho, ububanzi obulungisekayo besivinini somoya se-FFU bunqunyelwe emazingeni ambalwa. Ukuze kunqotshwe izici ezingafanele zokusebenza kokulawula i-FFU, ngokuklama amasekethe kagesi, wonke amaswishi esivinini esiningi e-FFU abekwe phakathi futhi abekwa ekhabetheni phansi ukuze kufezwe ukusebenza okuphakathi. Kodwa-ke, kungakhathaliseki ukuthi kuvela kuphi noma kukhona imikhawulo ekusebenzeni. Izinzuzo zokusebenzisa indlela yokulawula ukushintshashintsha ngesivinini esiningi ukulawula okulula kanye nezindleko eziphansi, kodwa kunezinkinga eziningi: njengokusetshenziswa kwamandla aphezulu, ukungakwazi ukulungisa isivinini kahle, ukungabi nesignali yempendulo, kanye nokungakwazi ukufeza ukulawula kweqembu okuguquguqukayo, njll.
3. Ukulawula ukulungiswa kwesivinini okungenazinyathelo
Uma kuqhathaniswa nendlela yokulawula ukushintshashintsha ngesivinini esiningi, ukulawula ukulungisa isivinini okungenasinyathelo kunomlawuli wesivinini owengeziwe ongenasinyathelo, okwenza isivinini sabalandeli be-FFU siguquguquke njalo, kodwa futhi sidela ukusebenza kahle kwenjini, okwenza ukusetshenziswa kwayo kwamandla kube phezulu kunendlela yokulawula ukushintshashintsha ngesivinini esiningi.
- Ukulawula ikhompyutha
Indlela yokulawula ikhompyutha ngokuvamile isebenzisa injini ye-EC. Uma kuqhathaniswa nezindlela ezimbili zangaphambilini, indlela yokulawula ikhompyutha inemisebenzi elandelayo ethuthukisiwe:
(1). Ukusebenzisa imodi yokulawula esabalele, ukuqapha kanye nokulawula i-FFU okuphakathi kungenziwa kalula.
(2). Iyunithi eyodwa, amayunithi amaningi kanye nokulawulwa kokuhlukanisa kwe-FFU kungenziwa kalula.
(3). Uhlelo lokulawula oluhlakaniphile lunemisebenzi yokonga amandla.
(4). Isilawuli kude esingakhethwa singasetshenziswa ukuqapha nokulawula.
(5). Uhlelo lokulawula lune-interface yokuxhumana egciniwe engaxhumana nekhompyutha noma inethiwekhi ephethe ukuze kufezwe imisebenzi yokuxhumana nokuphatha ekude. Izinzuzo ezivelele zokulawula ama-motor e-EC yilezi: ukulawula okulula kanye nobubanzi besivinini esikhulu. Kodwa le ndlela yokulawula inamaphutha athile abulalayo:
(6). Njengoba ama-motor e-FFU engavunyelwe ukuba namabhulashi egumbini elihlanzekile, wonke ama-motor e-FFU asebenzisa ama-motor e-EC angenamabhulashi, futhi inkinga yokushintshashintsha ixazululwa ngama-commutator kagesi. Ukuphila okufushane kwama-commutator kagesi kwenza impilo yesevisi yesistimu yokulawula yonke inciphe kakhulu.
(7). Lonke uhlelo luyabiza.
(8). Izindleko zokulungisa kamuva ziphezulu.
5. Indlela yokulawula kude
Njengesengezo sendlela yokulawula ikhompyutha, indlela yokulawula kude ingasetshenziswa ukulawula i-FFU ngayinye, ephelelisa indlela yokulawula ikhompyutha.
Ngamafuphi: izindlela ezimbili zokuqala zokulawula zisebenzisa amandla amaningi futhi azilula ukuzilawula; izindlela ezimbili zokugcina zokulawula zinesikhathi esifushane sokuphila kanye nezindleko eziphezulu. Ingabe ikhona indlela yokulawula engafinyelela ukusetshenziswa kwamandla okuphansi, ukulawula okulula, impilo yesevisi eqinisekisiwe, kanye nezindleko eziphansi? Yebo, leyo yindlela yokulawula ikhompyutha esebenzisa i-AC motor.
Uma kuqhathaniswa nama-motor e-EC, ama-motor e-AC anezinzuzo eziningi ezifana nesakhiwo esilula, usayizi omncane, ukukhiqizwa okulula, ukusebenza okuthembekile, kanye nentengo ephansi. Njengoba engenazo izinkinga zokushintshashintsha, impilo yawo yesevisi ide kakhulu kuneyama-motor e-EC. Isikhathi eside, ngenxa yokusebenza kwayo okungekuhle kokulawula isivinini, indlela yokulawula isivinini ibilokhu isetshenziswa yindlela yokulawula isivinini se-EC. Kodwa-ke, ngokuvela nokuthuthukiswa kwamadivayisi kagesi amasha kanye namasekethe amakhulu ahlanganisiwe, kanye nokuvela nokusetshenziswa okuqhubekayo kwemibono emisha yokulawula, izindlela zokulawula i-AC ziye zathuthuka kancane kancane futhi ekugcineni zizothatha indawo yezinhlelo zokulawula isivinini se-EC.
Endleleni yokulawula i-FFU AC, ihlukaniswe kakhulu ngezindlela ezimbili zokulawula: indlela yokulawula ukulawulwa kwe-voltage kanye nendlela yokulawula ukuguqulwa kwemvamisa. Indlela ebizwa ngokuthi indlela yokulawula ukulawulwa kwe-voltage iwukulungisa ijubane lemoto ngokushintsha ngqo i-voltage ye-motor stator. Ububi bendlela yokulawula i-voltage yilezi: ukusebenza kahle okuphansi ngesikhathi sokulawulwa kwesivinini, ukushisa okukhulu kwemoto ngesivinini esiphansi, kanye nobubanzi obuncane bokulawulwa kwesivinini. Kodwa-ke, ububi bendlela yokulawula i-voltage abubonakali kakhulu kumthwalo wabalandeli be-FFU, futhi kunezinzuzo ezithile ngaphansi kwesimo samanje:
(1). Uhlelo lokulawula isivinini seluvuthiwe futhi uhlelo lokulawula isivinini luzinzile, okungaqinisekisa ukusebenza okuqhubekayo okungenazinkinga isikhathi eside.
(2). Kulula ukuyisebenzisa futhi ishibhile uhlelo lokulawula.
(3). Njengoba umthwalo wefeni ye-FFU ulula kakhulu, ukushisa kwenjini akukubi kakhulu ngesivinini esiphansi.
(4). Indlela yokulawula i-voltage ifaneleka kakhulu kumthwalo wefeni. Njengoba ijika lomsebenzi wefeni le-FFU liyijika eliyingqayizivele lokudambisa, ububanzi bokulawula isivinini bungaba banzi kakhulu. Ngakho-ke, esikhathini esizayo, indlela yokulawula i-voltage nayo izoba yindlela enkulu yokulawula isivinini.
