Kungani izinjini zikagesi zisemathubeni amaningi okuthi ziphele manje kunakudala?
1. Ngenxa yokuthuthukiswa okuqhubekayo kobuchwepheshe bokufakelwa, ukuklanywa kwemoto kudinga kokubili ukuphuma okukhulisiwe kanye nevolumu encishisiwe, ukuze amandla okushisa emoto entsha abe mancane futhi abe mancane, futhi umthamo wokulayisha ngokweqile uya uba buthaka futhi ube buthaka;ngenxa yokuthuthukiswa kwezinga le-automation yokukhiqiza, injini iyadingeka ukuthi isebenze ngokujwayelekile ukuqala, ukubhuleka, ukuya phambili nokuhlehlayo, kanye nezindlela zokulayisha eziguquguqukayo, okubeka phambili izidingo eziphakeme zedivayisi yokuvikela imoto.Ngaphezu kwalokho, injini inendawo yokusebenzela ebanzi futhi ivame ukusebenza ezindaweni ezinokhahlo ngokwedlulele, njengomswakama, izinga lokushisa eliphezulu, uthuli, ukugqwala nezinye izikhathi.Ngaphezu kwalokho, kukhona okungahambi kahle ekulungisweni kwezimoto kanye nokushiywa ngaphandle kokuphathwa kwemishini.Konke lokhu kwenza izinjini zanamuhla zithambekele ekulimaleni kunakudala.
Kungani umphumela wokuvikela wezinto ezijwayelekile zokuvikela ungalungile?
2. Izisetshenziswa zendabuko zokuvikela izimoto ikakhulukazi ama-fuse nama-thermal relay.I-Fuse iyisisetshenziswa sokuvikela sakuqala nesilula kakhulu esingasisebenzisa.Eqinisweni, i-fuse isetshenziselwa ukuvikela ulayini wokuphakela amandla nokunciphisa ukunwetshwa kwebanga lephutha uma kwenzeka iphutha lesifunda esifushane.Akuyona isayensi ukucabanga ukuthi i-fuse ingavikela i-motor ku-short-circuit noma ukulayisha ngokweqile.Angazi, lokhu kungenzeka kubangele ukuthi injini ilimaze injini ngenxa yokwehluleka kwesigaba.Ama-thermal relay angamadivayisi asetshenziswa kakhulu okuvikela ukugcwala kwezimoto.Kodwa-ke, i-relay eshisayo inomsebenzi owodwa, ukuzwela okuphansi, iphutha elikhulu nokuzinza okubi, okuye kwaqashelwa iningi lezisebenzi zikagesi.Zonke lezi zinkinga zenza ukuvikelwa kwemoto kungathembeki.Kunjalo futhi;nakuba imishini eminingi ifakwe ama-relay ashisayo, isimo sokulimala kwezimoto esithinta ukukhiqizwa okuvamile sisavamile.
Umgomo wokukhetha umvikeli?
3. Inhloso yokukhetha idivayisi yokuvikela imoto akukhona nje ukunika amandla injini ukuthi isebenzise ngokugcwele umthamo wayo wokulayisha ngokweqile, kodwa futhi nokugwema umonakalo, nokuthuthukisa ukwethembeka kwesistimu yokushayela kagesi nokuqhubeka kokukhiqiza.Ngesikhathi esifanayo, lapho ukhetha idivayisi yokuvikela, izici eziningana eziphikisanayo kufanele zicatshangelwe, okungukuthi ukwethembeka, umnotho, isakhiwo esilula, ukusebenza okulula nokugcinwa, njll. Lapho izidingo zokuvikela zingafinyelelwa, idivayisi yokuvikela elula ibhekwa kuqala.Kuphela uma idivayisi yokuvikela elula ingakwazi ukuhlangabezana nezidingo, noma uma izidingo eziphezulu zibekwe ezicini zokuvikela, ukusetshenziswa kwedivayisi yokuvikela eyinkimbinkimbi kuyacatshangelwa.
Isivikeli semoto esikahle?
4. Isivikeli semoto esifanelekile asisona esisebenza kakhulu, noma okuthiwa sithuthuke kakhulu, kodwa kufanele sibe sisebenza kakhulu.Pho kungani iwusizo?Okusebenzayo kufanele kuhlangabezane nokuthembeka, umnotho, ukunethezeka nezinye izici, ngokusebenza kwezindleko eziphezulu.Ngakho yini enokwethenjelwa?Ukwethembeka kufanele kuqale kuhlangabezane nokuthembeka kwemisebenzi, efana nemisebenzi eyeqile kanye neyokuhluleka kwesigaba, okumele isebenze ngokuthembekile ekuhlulekeni okweqile kanye nesigaba okwenzeka ezikhathini ezihlukahlukene, izinqubo, nezindlela.Okwesibili, ukwethembeka kwayo (njengoba umvikeli ukuvikela abanye, kufanele abe nokuthembeka okuphezulu ikakhulukazi) kufanele kube nokuvumelana nezimo, ukuzinza nokuqina ezindaweni ezihlukahlukene ezinokhahlo.Umnotho: Yamukela idizayini ethuthukisiwe, isakhiwo esiphusile, ukukhiqizwa okukhethekile nokukhulu, yehlisa izindleko zomkhiqizo, futhi ilethe izinzuzo zezomnotho eziphezulu kakhulu kubasebenzisi.Ukunethezeka: Kufanele okungenani kufane nokudluliselwa okushisayo mayelana nokufakwa, ukusetshenziswa, ukulungiswa, izintambo, njll., kulula futhi kulula ngangokunokwenzeka.Ngenxa yalokhu, ochwepheshe abafanelekile sekuyisikhathi eside bebikezela ukuthi ukuze kwenziwe lula idivayisi yokuvikela imoto ye-elekthronikhi, uhlelo lokuklama olungenayo i-transformer kagesi (i-passive) kufanele lwakhiwe futhi lwamukelwe, futhi i-semiconductor (efana ne-thyristor) kufanele isetshenziselwe buyisela i-electromagnetic actuator ngoxhumana nabo.isici.Ngale ndlela, kungenzeka ukwenza idivayisi yokuzivikela equkethe inani elincane lezingxenye.Siyazi ukuthi imithombo esebenzayo izoholela ngokungathembeki.Enye idinga amandla okusebenza ukuze isebenze evamile, futhi lapho enye isiphumile esigabeni, izolahlekelwa amandla okusebenza nakanjani.Lokhu kuwukuphikisana okungenakunqotshwa.Ngaphezu kwalokho, idinga ukuthi ivulwe amandla isikhathi eside, futhi ithintwa kalula ukushintshashintsha kwamandla kagesi wegridi kanye nokushaqeka okukhulu kwamanje, futhi izinga layo lokuhluleka lizokwenyuka kakhulu.Ngakho-ke, imboni yokuvikela izimoto ibheka ukusebenza nokungenzi lutho njengengqophamlando yenqubekelaphambili yezobuchwepheshe.Njengomsebenzisi, imikhiqizo yokwenziwa kufanele futhi icatshangelwe kuqala lapho ukhetha.Isimo sokuthuthukiswa kokuvikelwa kwemoto.
Njengamanje, umvikeli wezimoto uye wathuthukiswa kusukela ohlotsheni lwemishini esikhathini esidlule kuya ohlotsheni lwe-elekthronikhi kanye nohlobo oluhlakaniphile, olungabonisa ngokuqondile okwamanje, i-voltage, izinga lokushisa kanye neminye imingcele ye-motor, ngokuzwela okuphezulu, ukuthembeka okuphezulu, okuningi. imisebenzi, ukulungisa iphutha okulungile, kanye nezinhlobo zamaphutha ezicacile ngemva kwesenzo sokuvikela., okungagcini nje ukunciphisa umonakalo we-motor, kodwa futhi kusiza kakhulu ukwahlulela kwephutha, okuhambisana nokuphathwa kwephutha kwesayithi lokukhiqiza futhi kufinyeze isikhathi sokubuyisela.Ngaphezu kwalokho, ubuchwepheshe bokutholwa kwe-motor eccentricity besebenzisa inkambu kazibuthe ye-motor air-gap yenza kube nokwenzeka ukuqapha isimo sokugqokwa kwezimoto ku-inthanethi.Ijika libonisa ukushintshwa kwethrendi ye-motor eccentricity, futhi ingakwazi ukubona kusenesikhathi ukuguga kanye nendilinga yangaphakathi, indilinga yangaphandle namanye amaphutha.Ukutholwa kusenesikhathi, ukwelashwa kusenesikhathi, ukugwema izingozi ezishanelayo.
