Isimiso sokusebenza sokumelana nabalandeli be-elekthronikhi, ukumelana nabalandeli be-elekthronikhi kuyizimpawu eziphukile.
Guqula ugesi ube ukushisa
Ukumelana kukagesi kwefeni kagesi kusebenza kakhulu ngokuguqula ugesi ube amandla okushisa.
I-resistor kufeni kagesi, eyaziwa nangokuthi i-thermistor, inendima ebalulekile ekuqapheni izinga lokushisa kwama-motor windings. Lapho izinga lokushisa lokugoba kwenjini landa, inani lokumelana le-thermistor lizoncipha. Lolu shintsho lubangelwa ubudlelwano obuphakathi kwe-negative temperature coefficient phakathi kwenani lokumelana le-thermistor kanye nezinga lokushisa, okungukuthi, njengoba izinga lokushisa landa, inani lokumelana lizoncipha. Lapho inani lokumelana lifinyelela izinga lokushisa elithile, lizoncipha liye enanini elithile, okuzobangela ukuthi isekethe ye-pre-value icime ukusebenza, ukuze ifeni kagesi iyeke ukusebenza. Le ndlela empeleni iwumphumela wokuvikela kufeni kagesi, ivimbela umonakalo ngenxa yokushisa ngokweqile.
Ngaphezu kwalokho, isimiso sokusebenza sokumelana sihilela nokuguqulwa kombane. Lapho umbane udlula ku-resistor, ngenxa yomphumela we-thermoelectric we-resistor, izinga lokushisa lobuso be-resistor lizokhuphuka, futhi inani lamanje nalo lizoshintsha. Ngokulungisa umbane, amapharamitha okumelana angalungiswa, njengenani lokumelana kanye nenani lamanje, ukuze kufezwe ukuzinza kwesekethe futhi kuvinjelwe isenzakalo sombane oweqile.
Ekusetshenzisweni kwabalandeli be-elekthronikhi, ukumelana akugcini nje ngokudlala indima yokuvikela, kodwa futhi kuhlanganyela enqubweni yokulawula isivinini kanye nokulawula izinga lokushisa kwefeni kagesi. Isibonelo, kufeni yokupholisa ye-elekthronikhi yezimoto, ukusebenza kwefeni kulawulwa ngezindlela ezahlukene zokulawula (njengemodi yokulawula ethi "thermistor switch + relay"), futhi ijubane lefeni lilungiswa ngokuzenzakalelayo ngokuya ngokushisa kwamanzi noma isivinini. Le ndlela yokulawula ayigcini nje ngokuthuthukisa ukusebenza kahle kwefeni kagesi, kodwa futhi iqinisekisa ukusebenza kwayo okuphephile.
Izimpawu eziyinhloko zokwehluleka kokumelana nomshini kagesi zifaka:
Ukuphuma komoya akukwazi ukulungiswa, okungukuthi, ukuphuma komoya kwefeni akukwazi ukulungiswa njengoba kudingeka.
Ayikho igiya elingu-1234, kukhona indawo eyodwa yokuphuma, noma ayisebenzi.
Lezi zimpawu zibonisa ukuthi i-resistor yefeni kagesi kungenzeka yonakele, okwenza ingasebenzi kahle. I-resistor isebenza njengesivikelo somkhawulo wamanje kanye nokuvikela i-overvoltage kusekethe, futhi uma yonakele, ingabangela ukuthi ukuphuma komoya kwefeni kungakwazi ukulungiswa, noma kungase kungasebenzi nhlobo. Ngaphezu kwalokho, lapho i-resistor isebenza ngokujwayelekile, ukumelana kwayo akunamkhawulo, lapho i-voltage yokufaka idlula inani elithile, ukumelana kwayo kuzoba kuncane ngokuzumayo, ukuze isekethe ibe yi-short circuit, okuphoqa i-fuse ukuthi ishe ifushane, idlale indima ekuvikeleni umshini.
Indlela yokukala ukumelana kwefeni kagesi ngendlela efanele
Okokuqala, indima yokumelana nogesi kanye namaphutha avamile
Ukumelana kwefeni kagesi kungenye yezingxenye ezibalulekile zokulawula isivinini sokusebenza kwenjini, esibonakala ngokushintsha i-voltage yokunikezwa kwamandla. Amaphutha avamile afaka phakathi ukulimala kokumelana, ukuxhumana okungekuhle noma i-open circuit, njll., okuzobangela ukuthi injini ingasebenzi kahle.
Okwesibili, izinyathelo nezindlela zokulinganisa ukumelana
1. Nqamula ugesi bese ususa isembozo sefeni ukuze uveze ukumelana.
2. Sebenzisa i-multimeter ukuze uthinte induku yokulinganisa kuzo zombili izinhlangothi zokumelana. I-multimeter kufanele isethwe kugiya lokulinganisa ukumelana. Uma ukumelana kungalungiseka, setha i-multimeter kugiya le-rheostat ukuze ukumelana kufundwe kahle.
3. Funda inani lokumelana bese uliqhathanisa nenani lokulinganisa lemitha yokumelana. Uma ukufundwa kuseduze nenani lokulinganisa, ukumelana kujwayelekile; Ngaphandle kwalokho ukumelana kuyonakala.
Okwesithathu, izinyathelo zokuphepha
1. Lapho kulinganiswa ukumelana, ugesi kufanele ukhishwe kuqala ukuze kugwenywe izingozi.
2. Uma kusetshenziswa i-multimeter ukukala ukumelana okulungisekayo, jika i-resistor ibe yinani eliphezulu ngaphambi kokuhlola ukuze ugweme ukulimala kwe-resistor.
3. Uma ukuthintana kokumelana kungalungile, sebenzisa insipho yokuhlanza izingxenye zokuthintana bese uhlola ukuthi izikulufo ziboshiwe yini.
Isiphetho se-Iv.
Ngokusebenzisa indlela engenhla yokulinganisa ukumelana, singanquma ngokushesha nangokunembile ukuthi ukumelana kwefeni kagesi konakele yini, ukuze sikushintshe ngesikhathi futhi siqinisekise ukusebenza okuvamile kwefeni kagesi. Ngesikhathi esifanayo, kunconywa ukuthi unake ukuphepha lapho usebenzisa amafeni kagesi futhi ungawasebenzisi ngokweqile isikhathi eside.
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
