Isimiso sokusebenza sokumelana ne-electronic fan, ukumelana nabalandeli be-elekthronikhi kuyizimpawu eziphukile.
Guqula i-electric current ibe ukushisa
Ukumelana nogesi kwefeni ye-elekthronikhi kusebenza ikakhulukazi ngokuguqula okumanje kube amandla okushisa.
I-resistor ku-fan ye-electronic, eyaziwa nangokuthi i-thermistor, inendima ebalulekile ekuqapheni izinga lokushisa lama-motor windings. Lapho izinga lokushisa le-motor winding likhuphuka, inani lokumelana le-thermistor lizokwehla. Lolu shintsho lubangelwa ubudlelwane obubi bokushisa kwe-coefficient phakathi kwenani lokumelana le-thermistor nezinga lokushisa, okungukuthi, njengoba izinga lokushisa likhuphuka, inani lokumelana lizokwehla. Uma inani lokumelana lifinyelela izinga lokushisa elithile, lizokwehla libe yinani elithile, elizokwenza ukuthi isekethe ye-pre-value ivale ukusebenza, ukuze ifeni kagesi iyeke ukusebenza. Lo mshini empeleni uwumphumela ovikelayo ku-fan kagesi, uvimbela ukulimala ngenxa yokushisa ngokweqile.
Ngaphezu kwalokho, umgomo wokusebenza wokumelana nawo ubandakanya ukuguqulwa kwamanje. Lapho i-current idlula i-resistor, ngenxa yomphumela we-thermoelectric we-resistor, izinga lokushisa elingaphezulu le-resistor lizokhuphuka, futhi inani lamanje lizoshintsha. Ngokulungisa i-current, imingcele yokumelana ingashintshwa, njengenani lokumelana nenani lamanje, ukuze kuzuzwe ukuzinza kwesifunda futhi kuvimbele i-overcurrent phenomenon.
Ekusetshenzisweni kwabalandeli be-elekthronikhi, ukumelana akugcini nje ukudlala indima yokuzivikela, kodwa futhi kubamba iqhaza ekulawuleni isivinini kanye nenqubo yokulawula izinga lokushisa lomlandeli kagesi. Isibonelo, ku-fan yokupholisa ye-elekthronikhi yezimoto, ukusebenza kwefeni kulawulwa ngezindlela ezahlukene zokulawula (njengemodi yokulawula "i-thermistor switch + relay"), futhi isivinini se-fan silungiswa ngokuzenzakalelayo ngokuvumelana nezinga lokushisa lamanzi noma isivinini. Le ndlela yokulawula ayigcini nje ukuthuthukisa ukusebenza kahle kwe-fan kagesi, kodwa futhi iqinisekisa ukusebenza kwayo okuphephile.
Izimpawu eziyinhloko zokwehluleka ukumelana nabalandeli bakagesi zihlanganisa:
Ukukhishwa komoya akukwazi ukulungiswa, okungukuthi, ukuphuma komoya kwefeni akukwazi ukulungiswa njengoba kudingekile.
Alikho igiya le-1234, kunendawo eyodwa kuphela, noma ayisebenzi.
Lezi zimpawu zibonisa ukuthi i-resistor ye-fan ye-elekthronikhi ingase yonakaliswe, ibangele ukuthi ingasebenzi kahle. I-resistor isebenza njengomkhawulo wamanje kanye nokuvikelwa kwe-overvoltage kusekethe, futhi uma yonakalisiwe, ingabangela ukuphuma komoya kwefeni ukuthi kungakwazi ukulungiswa, noma ingase ingasebenzi nhlobo. Ngaphezu kwalokho, lapho i-resistor isebenza ngokujwayelekile, ukumelana kwayo akupheli, lapho i-voltage yokufaka idlula inani elithile, ukumelana kwayo kuyoba kuncane ngokuzumayo, ukuze isifunda sibe yisifunda esifushane, siphoqelele i-fuse ukuba ishise isikhashana, ibambe iqhaza ukuvikela umshini.
Ungakala kanjani ukumelana nabalandeli bakagesi ngendlela efanele
Okokuqala, indima yokuphikiswa kwabalandeli bakagesi kanye namaphutha avamile
Ukumelana kwefeni kagesi kungenye yezingxenye ezibalulekile zokulawula ijubane lokugijima lemoto, elibonakala ngokushintsha amandla kagesi. Amaphutha avamile ahlanganisa ukulimala kokumelana, ukuthintana okungalungile noma isifunda esivulekile, njll., okuzokwenza ukuthi injini ingasebenzi kahle.
Okwesibili, izinyathelo nezindlela zokulinganisa ukumelana
1. Nqamula ugesi bese ususa ikhava yabalandeli ukuze uveze ukumelana.
2. Sebenzisa i-multimeter ukuze uthinte induku yokulinganisa kuzo zombili iziphetho zokumelana. I-multimeter kufanele isethwe egiyeni lokulinganisa ukumelana. Uma ukumelana kulungiswa, setha i-multimeter kugiya le-rheostat ukuze ukumelana kufundwe kahle.
3. Funda inani lokumelana futhi uliqhathanise nenani lokulinganisa lemitha yokumelana. Uma ukufundwa kuseduze nenani lokulinganisa, ukumelana kuvamile; Ngaphandle kwalokho ukumelana kulimale.
Okwesithathu, izinyathelo zokuphepha
1. Lapho ukala ukumelana, ukunikezwa kwamandla kufanele kukhishwe kuqala ukuze kugwenywe izingozi.
2. Uma i-multimeter isetshenziselwa ukukala ukumelana okulungiswayo, jikisa i-resistor ibe yinani eliphakeme ngaphambi kokuhlolwa ukuze ugweme ukulimala kwesiphikisa.
3. Uma ukuthintana nokumelana kungalungile, sebenzisa okokuhlanza ukuze uhlanze izingxenye zokuxhumana futhi uhlole ukuthi izikulufi ziboshiwe yini.
Iv. Isiphetho
Ngokusebenzisa le ndlela engenhla yokulinganisa ukumelana, singakwazi ukunquma ngokushesha futhi ngokunembile ukuthi ukuphikiswa kwabalandeli bakagesi konakalisiwe, ukuze kushintshwe ngesikhathi futhi kuqinisekiswe ukusebenza okuvamile kwe-fan kagesi. Ngesikhathi esifanayo, kunconywa ukuba unake ukuphepha uma usebenzisa abalandeli bakagesi futhi ungawasebenzisi ngokweqile isikhathi eside.
Sicela usishayele uma udinga imikhiqizo enjalo.
