Uma injini ivaliwe isikhathi eside, izosha.Lena inkinga evame ukuhlangana nayo ohlelweni lokukhiqiza, ikakhulukazi kumamotho alawulwa ngabaxhumi be-AC. Ngabona othile ku-intanethi ehlaziya isizathu, okungukuthi ngemva kokuba i-rotor ivinjiwe, amandla kagesi awakwazi ukuguqulwa abe amandla omshini futhi ashiswe.Kuthe ukujula lokho. Ake sikuchaze ngendlela evamile, ukuze kuthi uma uhlangabezana nalolu hlobo lwento emsebenzini, umphathi abuze ukuthi kungani injini ishile, ngaphandle kokusebenzisa amagama abantu abavamile. Bese uqhamuka nezindlela ezingenzeka zokuvimbela injini ukuthi ingami, uqinisekise ukuphepha kwemoto, wonge imali yenkampani, futhi umsebenzi wakho uzohamba kahle. 1. Izindlela zokudluliswa kwezimoto ezisekela okokusebenza zihlukile, futhi izindlela zokuvikela imoto zihlukile.Uma injini yokudlulisa engunxantathu ihlangabezana nomthwalo owedlulele noma ukuma, ibhande elingunxantathu lizoshibilika ukuze kuvikelwe ukuphepha kwemoto nezinto zokusebenza.Bese kusetshenziswa umjikelezo wokulawula ukusatshalaliswa kwamandla.Ukuvikelwa kwe-relay eshisayo noma isivikeli semoto esikhethekile. Kukhona ukungaqondi lapha.Lapho opharetha ehlangana netafula ngezizathu ezingaziwa, esikhundleni sokuhlanza okokusebenza nokuxazulula imbangela yetafula, uyiqala ngokuphindaphindiwe.Njengoba uhambo lokuvikela i-relay eshisayo, uma lungakwazi ukuqala, lusetha kabusha ngesandla bese luqala futhi, ukuze injini isheshe kakhulu.Kwasha. Ngemuva kokuthi i-rotor ivinjiwe, okwamanje ingakhula izikhathi eziningana noma izikhathi eziyishumi.Uma i-current elinganiselwe ye-motor idlula kakhulu, i-winding izoshiswa.Noma ingase iphule isendlalelo sokufakelwa, ibangele isifunda esifushane phakathi kwezigaba noma isifunda esifushane kugobolondo. Isivikeli semoto asiyona i-panacea.Ukuze ugweme ukushisa i-motor, kuyadingeka ukusebenzisa isivikeli futhi usebenzise ngokuqinile imithetho yokusebenza ephephile.Uma imbangela ye-stall ihlangene, i-motor ayikwazi ukuvulwa ngokuphindaphindiwe ngaphandle kokuqeda imbangela ye-stall. Uma ufuna ukuvilapha futhi ungazihlanzi izinto zokusebenza, ukuqala okuphoqelelwe okuqhubekayo kuzoshisa injini. 2. Ngokuthuthuka kobuchwepheshe, ukulawulwa kwe-frequency converter sekuyinto evamile.Lezi zilawuli zobuchwepheshe obuphezulu zinesendlalelo esengeziwe sokuvikela uma kuqhathaniswa nesilawuli se-AC contactor.Isiguquli sefrikhwensi sivikela ngokuzenzakalelayo ekulayishweni ngokweqile noma ekujikelezweni okufushane, futhi asiqedi izingozi ezifihliwe zokuma noma ukujikeleza okufushane.Uma uqala ngokuphindaphindiwe Cha. Ngakho lolu hlobo lwesekethe ngeke lushise injini? Azikho izinyathelo zokuvikela ezinamandla onke.Ngemva kokuba i-inverter ivinjiwe futhi yakhubeka, u-opharetha ohlakaniphile noma osebenza ngogesi ongazi okuningi uzosetha kabusha i-inverter ngokuqondile futhi ayiqale futhi.Ngemuva kwemizamo embalwa eyengeziwe, i-inverter izoshisa futhi ihlale iphukile.Isiguquli sefrikhwensi asikwazi ukulawula injini. Noma ukusetha kabusha okwenziwayo kuphoqa ukuqala okuningi, okubangela ukuthi injini ishise kakhulu futhi iphele. Ngakho-ke, kuvamile ukuthi izinjini zimiswe, kodwa ukushisa injini kusho ukusebenza okungafanele.Gwema ukusebenza okungalungile ukugwema ukushisa injini. 3. Sebenza kanzima ekulawulweni kwemoto ukuze uqinisekise ukusebenza okuphephile kwenjini.I-thermal relay nesivikeli semoto kufanele ihlolwe njalo ukuze kubonakale ukuthi isifunda sokulawula singanqanyulwa yini.Kunenkinobho ebomvu ku-relay eshisayo.Icindezele phakathi nokuhlola okuvamile ukuze ubone ukuthi inganqamuka yini.Vula umugqa. Uma ingakwazi ukunqanyulwa, kufanele ishintshwe ngesikhathi. Ukwengeza, hlola ukuthi ingabe i-motor thermal relay, isilungiselelo samanje esilungisiwe kanye nokulinganisa kwamanje kwemoto evikelekile ngaphambi kokuqala umshini nsuku zonke, futhi azikwazi ukudlula amandla amanje alinganiselwe enjini. 4. Ukukhethwa kwe-motor power circuit breaker kufanele kusekelwe kumanje olinganiselwe we-motor.Angeke ibe nkulu kakhulu.Uma inkulu kakhulu, ngeke inikeze ukuvikelwa kwesifunda esifushane. 5. Vimbela injini ekuphelelweni kwesigaba.Akuvamile ukuthi injini ishe ngenxa yokuntuleka kwesigaba.Uma abaphathi bengekho, kuzokwenzeka kalula.Ngaphambi kokuqala umshini, sebenzisa i-multimeter ukuhlola amandla kagesi ukuze ubone ukuthi i-voltage yezigaba ezintathu iyahambisana yini futhi unqume ukuthi i-voltage yokuphakelwa kwamandla ijwayelekile yini. Ngemva kokuqalisa, sebenzisa imitha yokubopha yamanje ukuze ulinganise amandla ezigaba ezintathu zenjini ukuze ubone ukuthi ibhalansile yini.Imisinga yezigaba ezintathu iyafana futhi awukho umehluko omkhulu.Njengoba izigaba ezintathu zingalinganiswa ngesikhathi esisodwa, okwamanje ihlukile ngenxa yomthwalo. Lokhu kungaqeda ukusebenza kokulahlekelwa kwesigaba semoto kusenesikhathi.
