Ekukhiqizeni kwanamuhla kwezimboni, ama-motor kagesi asetshenziswa kabanzi.Izinhlobo ezahlukahlukene, amafomu kagesi kanye namazinga kagesi wamamotho kagesi avela ngokungapheli.Okulandelayo incazelo emfushane yezizathu zokusebenza kwesigaba esisodwa kanye nezinyathelo zokuvimbela.
Ukuhlukaniswa kwezinjini
Amamotho kagesi angahlukaniswa abe ama-DC motors, ama-asynchronous motors nama-synchronous motors ngokuya ngezakhiwo ezahlukene kanye nemigomo yokusebenza.Amamotho e-synchronous angabuye ahlukaniswe abe amamotho asebenza ngozibuthe ahambisanayo, amamotho ahambisanayo anokungabaza kanye nama-hysteresis synchronous motors.Ama-asynchronous motors angahlukaniswa abe ama-induction motors kanye nama-AC commutator motors.Ama-motor induction aphinde ahlukaniswe abe ama-motor asynchronous ezigaba ezintathu, ama-motor asynchronous esigaba esisodwa kanye nama-motor pole asynchronous motors.Ama-AC commutator motors aphinde ahlukaniswe abe yizinjini zesigaba esisodwa,Izinjini ze-AC kanye ne-DC ezinezinjongo ezimbili kanye nama-motor repulsion.
Izingozi ezibangelwa ukusebenza kwesigaba esisodwa sezigaba ezintathu ze-asynchronous motors
Izigaba ezintathu ze-asynchronous motors zinezindlela ezimbili zokufaka izintambo: uhlobo lwe-Y no-Δ-type.Uma injini exhunywe ngu-Y isebenza ngesigaba esisodwa, okwamanje esigabeni esinqanyuliwe inguziro.Imisinga yesigaba yezinye izigaba ezimbili iba imisinga yomugqa.Ngasikhathi sinye, izodala i-zero point drift kanye ne-voltage yayo yesigaba nayo izokhuphuka.
Lapho i-motor ene-Δ-type wiring inqanyulwa ngaphakathi, i-motor ishintsha ibe i-V-type ngaphansi kwesenzo sokuphakelwa kwamandla kwezigaba ezintathu, kanti okwamanje izigaba ezimbili zikhuphuka izikhathi ezingu-1.5.Uma injini enezintambo zohlobo lwe-Δ inqanyulwa ngaphandle, ilingana namawindi ezigaba ezimbili axhunywe ochungechungeni kanye neqembu lesithathu lamawindi axhunywe ngokuhambisana phakathi kwama-voltage emigqa emibili.Umsinga kokubiliamawindiokuxhunywe ochungechungeni kuhlala kungashintshile.I-current eyengeziwe yeqembu lesithathu izokwenyuswa izikhathi ezingu-1.5.
Ukufingqa, lapho injini isebenza ngesigaba esisodwa, ijika layo elijikajikayo likhuphuka ngokushesha, futhi igobolondo elimazombezombe nelensimbi lishisa ngokushesha, lishise okokufaka okumazombezombe bese kushisa i-motor winding, kuthinte imisebenzi evamile yokukhiqiza.Uma indawo esizeni ingezinhle, indawo ezungezile izonqwabelana.Kukhona izinto ezivuthayo ezingadala umlilo kalula futhi zidale imiphumela emibi kakhulu.
Izimbangela zokusebenza kwesigaba esisodwa semoto kanye nezinyathelo zokuvimbela
1.Lapho i-motor ingakwazi ukuqala, kunomsindo ozwakalayo, futhi igobolondo liyakhuphuka izinga lokushisa noma ijubane liyancipha kakhulu ngesikhathi sokusebenza, futhi izinga lokushisa likhuphuka, ukunikezwa kwamandla kufanele kunqanyulwe ngokushesha futhi imbangela yokwehluleka kufanele. kutholakale ngokucophelela.Thola ukuthi isimo esingenhla sibangelwa ukuntuleka kwesigaba.
I-2.Lapho umugqa wamandla wesifunda esiyinhloko mncane kakhulu noma uhlangabezana nomonakalo wangaphandle, ukunikezwa kwamandla kwesigaba sesithathu se-motor kuzodala ukusebenza kwesigaba esisodwa ngenxa yokushisa kwesigaba noma ukushaya kwamandla angaphandle.Umthamo wokuthwala ophephile wentambo yamandla eyinhloko yi-1.5 kuya ku-2.5 izikhathi zamanje ezilinganiselwe zenjini, futhi umthamo wokuthwala ophephile wentambo kagesi uhlobene eduze nendlela yokubeka intambo yamandla.Ikakhulukazi uma ihambisana noma ihlangana nepayipi lokushisa, isikhawu kufanele sibe sikhulu kuno-50cm.Umthamo wokuthwala ophephile wentambo yamandla engakwazi ukusebenza isikhathi eside ekukhuphukeni kwezinga lokushisa elingu-70°C ngokuvamile ungahlolwa ngemanuwali yomsebenzi kagesi.Ngokusho kokuhlangenwe nakho kwangaphambilini, umthamo ophephile wokuthwala izintambo zethusi ngu-6A ngemilimitha yesikwele, kanti owezintambo ze-aluminium ngu-4A ngemilimitha yesikwele.Ngaphezu kwalokho, amajoyinti okuguqula i-copper-aluminium kufanele asetshenziswe lapho kuhlanganiswa ucingo lwe-copper-aluminium, ukuze kugwenywe i-oxidation phakathi kwezinto zethusi-aluminium futhi kuthinte ukumelana nokuhlangana.
3.Ukucushwa okungalungile kokushintshwa komoya noma isivikelo sokuvuza kungase kubangele ukusebenza kwesigaba esisodwa semoto.Uma ukucushwa komshini womoya kukuncane kakhulu, kungase kube ngenxa yokuthi amandla amanje amakhulu kakhulu ukushisa othintana nabo bangaphakathi bomshini wokushintsha umoya, okuholela ekutheni ukumelana nokuxhumana kwesigaba kukhulu kakhulu, kwakha ukusebenza kwemoto yesigaba esisodwa.Isilinganiso samanje sokushintshwa komoya kufanele sibe izikhathi ezingu-1.5 kuya kwezingu-2.5 kunamanje olinganiselwe wenjini.Ngaphezu kwalokho, ngesikhathi sokusebenza kwe-motor, kufanele kuqashelwe ukuthi ukucushwa kwe-air switch kuncane kakhulu, noma ikhwalithi ye-air switch ngokwayo iyinkinga, futhi ukushintshwa komoya okufanelekile kufanele kushintshwe.
I-4.Umugqa wokuxhuma phakathi kwezingxenye zekhabhinethi yokulawula ushisiwe, okungabangela ukuthi injini isebenze ngesigaba esisodwa.Izizathu zokushiswa kolayini wokuxhuma zimi kanje:
① Ulayini wokuxhuma mncane kakhulu, lapho umthamo wamanje wemoto ukhuphuka, ungase ushise ulayini wokuxhuma.② Izixhumi emikhawulweni yomibili yolayini wokuxhuma azixhumene kahle, okubangela ukuthi ulayini woxhumano ushise ngokweqile, ngaleyo ndlela ushise ulayini wokuxhuma.Kukhona umonakalo omncane wezilwane, njengokukhuphuka kwamagundane phakathi kwemigqa emibili, okubangela ukujikeleza okufushane phakathi kwemigqa futhi kushise umugqa wokuxhuma.Isixazululo siwukuthi: ngaphambi kokuqala ukusebenza ngakunye, ikhabhinethi yokulawula kufanele ivulwe ukuze ihlole ngokucophelela ukuthi umbala womugqa ngamunye wokuxhuma ushintshile yini, nokuthi isikhumba sokushisa sinamamaki okushisa.Ulayini wamandla uhlome ngokufanele ngokuvumelana nomthwalo wamanje wemoto, futhi isixhumi sixhunywe ngokuvumelana nezidingo zenqubo.
I-Peroration
Ekwakhiweni, kufanele sihambisane ngokuqinile nezincazelo zezinqubo ezihlukahlukene zokwakha ukuze kuqinisekiswe izinga lokufakwa.Ukugcinwa okuvamile kwemishini ehlukahlukene kanye nokuhlolwa okuvamile nokulungiswa ngesikhathi sokusebenza ngokuqinisekile kuzogwema ukulahlekelwa okungadingekile kanye nezingozi ezibangelwa ukusebenza kwesigaba esisodwa se-motor.
