Umgomo wokusebenza we-blower motor resistor
I-resistor ye-blower motor ilawula isivinini se-blower motor ngokushintsha usayizi wamanje, ngaleyo ndlela ilawula isivinini somoya opholile. Empeleni, iyi-resistor eguquguqukayo ekhawulela ugesi ngokwandisa noma ukunciphisa inani lokumelana, ifinyelele ukushintsha kusuka esivinini esiphansi kuya esivinini esiphezulu. Nansi incazelo eningiliziwe:
I-resistor ilawula kanjani isivinini somoya?
Ingqikithi ye-blower motor resistor iwukuvimbela ukugeleza kwamanje. Uma ugesi uncane, ugesi ujikeleza kancane; uma ugesi umkhulu, ujikeleza ngokushesha. Ngokukhethekile, uhlukaniswe ngezinyathelo ezintathu:
Isivinini somoya esiphansi (njengegiya lokuqala): Ugesi udlula kuma-resistor amaningi ochungechunge (ngokuvamile angu-3), inani lokumelana likhulu kunawo wonke, ugesi omncane kunawo wonke, kanti injini yomoya ovunguzayo ijikeleza ngesivinini esiphansi.
Isivinini somoya esimaphakathi (njengegiya lesibili kuya kwelesithathu): Ugesi udlula kuma-resistor ambalwa (2 noma 1), inani lokumelana liyancipha, ugesi uyanda, futhi injini yomshini wokufutha iyanda.
Isivinini somoya esiphezulu (njengegiya lesi-4): Ugesi udlula ama-resistor futhi unikezwa ngqo, inani lokumelana liseduze no-zero, ugesi yiwona omkhulu kunayo yonke, futhi injini yomshini wokufutha ijikeleza ngesivinini esigcwele.
Uyini umehluko phakathi kwezindlela zokulawula zendabuko nezesimanje?
Ukulawulwa kwe-resistor yendabuko: Kuncike ekushintsheni okungokoqobo ukushintshanisa inhlanganisela ye-resistor. Isibonelo, inkinobho ephaneli yokupholisa umoya ikhetha ngqo inani lama-resistor ochungechunge, okulula kodwa okungasebenzi kahle (ingxenye yamandla kagesi iguqulwa ibe ukushisa bese ichithwa).
Ukulawulwa kwe-PWM yesimanje: Kuvame ukusetshenziswa ezimotweni ezintsha ukuze kulungiswe ngamasignali e-pulse (PWM). I-chip yekhompyutha epholile ithumela amasignali ukulawula isikhathi sokuvulwa kwamaswishi kagesi (njenge-MOSFET), ishintsha ngokungaqondile i-voltage kanye nesivinini sokuphuma, okunembe kakhulu futhi konga amandla.
Kwenzekani uma i-resistor iphuka?
Uma i-resistor isha noma ingathintani kahle, injini ye-blower ingasebenza kuphela ngegiya eliphezulu kakhulu (ugesi uqonde ngqo) noma ingabi nomoya nhlobo (i-fuse evunguzayo).
I-resistor ye-blower motor eshile ingalungiswa, kodwa ngokuvamile kunconywa ukuthi uyishintshe ngentsha ngoba ingaphinde ishe noma ibe nezingozi zokuphepha ngemva kokulungiswa. Nasi ukuhlaziywa kanye nesiphakamiso esithile:
Indlela yokulungisa (yesimo esiphuthumayo kuphela)
Uma i-resistor ishiswe kancane (njengokuxega kwe-solder), ungazama ukuyilungisa:
Ukusebenza kokuvala ugesi: Okokuqala nqamula i-terminal engemihle yebhethri lemoto ukuze ugweme izingozi ze-short circuit.
Shibilikisa ijoyinti le-solder elikhululekile: Sebenzisa insimbi yokushibilikisa kanye ne-solder ukuze uxhume kabusha ishidi lethusi le-resistor, bese ulicindezela ngokuqinile ngaphambi kokuba liphole (ngaphandle kwalokho i-solder ingase indize).
Hlola umphumela: Ngemva kokufaka kabusha, qala i-air conditioner bese uhlola ukuthi ivolumu yomoya yamagiya 1 kuya ku-3 ibuyiselwe yini.
Qaphela: I-resistor elungisiwe ingasha futhi ngenxa yokuguga noma izinkinga zokushabalalisa ukushisa, futhi ukusebenza okungafanele kungalimaza isekethe.
Kungani kunconywa ukufaka esikhundleni se-resistor entsha?
Iphephile futhi ithembekile: I-resistor elungisiwe ivame ukuphinda amaphutha, kanti ukufaka ingxenye entsha esikhundleni sayo kungaxazulula inkinga ngokuphelele.
Ukusebenza okulula: Kwabaningi abasebenzisa amamodeli, i-resistor itholakala ngemuva kwebhokisi legilavu lomgibeli, futhi ingashintshwa ngokususa izikulufo ezimbili (kuthatha cishe imizuzu engama-30).
Ukugwema umonakalo ohambisanayo: Ukushiswa yi-resistor kuvame ukubangelwa ukumelana ngokweqile kwenjini. Ukungayishintshi i-resistor entsha kungalimaza i-blower motor noma i-fuse.
Isitolo sokwenza izinto ngokwakho noma sobungcweti?
Izimo Zokuzenzela: Udinga ukulungisa isikrufu se-Allen kanye nensimbi yokunamathisela (kubasebenzisi abanolwazi kuphela), bese ubheka ividiyo yokulungisa yomodeli wakho.
I-resistor ye-blower motor iyisici esibalulekile ohlelweni lokupholisa umoya emotweni olulawula isivinini se-blower motor. Ukwehluleka kwayo kuzothinta ukusetshenziswa okuvamile kwe-air conditioner. Okuqukethwe okulandelayo kusekelwe ezimweni ezivamile.
Izimpawu eziyinhloko zokwehluleka kwe-blower motor resistor zifaka:
Ukulawulwa kwevolumu yomoya okungavamile: Uphawu olujwayelekile ukungabi nomoya noma umoya obuthakathaka kumagiya anesivinini esiphansi (njengegiya lokuqala, elesibili, nelesithathu), kuyilapho igiya elinesivinini esiphezulu (igiya lesine) livamile. Lokhu kungenxa yokuthi amagiya anesivinini esiphansi afinyelela ukulawulwa kwesivinini ngokuhlukaniswa kwe-resistor voltage, futhi lapho i-resistor yonakele, ayikwazi ukushintsha amagiya, okuholela ekungakwazini ukulungisa ivolumu yomoya noma ivolumu yomoya efanayo kuwo wonke amagiya.
Injini yomshini wokufaka umoya ayisebenzi noma ayisebenzi ngendlela engavamile: Ingabonakala njengenjini engajikelezi, ukujikeleza okuhamba kancane, ukuqala okunzima, noma okuhambisana nemisindo engavamile (njengokuhumzela noma ukuchofoza), okuvame ukuhlobene nokushiswa yi-resistor, ukuguguleka kwamabhere, noma izinto zakwamanye amazwe ezinamathele ezinsikeni.
Izinkinga ezihlobene nesistimu: Ezimweni ezimbi kakhulu, ukwehluleka kwe-resistor kungabangela ukugcwala ngokweqile kwesekethe, okuholela ekuqhumeni kwe-fuse, iphutha le-ECU, noma ukukhanya kwesibani sokuhlola injini.
Izimbangela eziyinhloko zokwehluleka zifaka: Umonakalo wokushisa ngokweqile: Uma i-resistor isebenza isikhathi eside ngaphandle kokushabalalisa ukushisa okufanele, noma uma i-fan bearing iguga noma uthuli luqoqana ezinsikeni, okwandisa ukumelana futhi kubangele ugesi owedlulele, i-resistor ingashisa kakhulu futhi ishe.
Ugesi ongajwayelekile: Ukwehluleka kwenjini yefeni (njengokujima kwangaphakathi noma ukuguguleka kwengalo) kungabangela ugesi oweqile, kusheshise ukuguga kwe-resistor; imininingwane engalungile yefuse noma izifunda ezimfushane zesekethe nakho kungabangela ukuqhuma okungajwayelekile.
Izinkinga zekhwalithi ye-resistor uqobo: Amandla anganele, ikhwalithi yezinto ezibonakalayo embi, noma ukushisela okuxekethile (njengamajoyinti e-solder axekethile) kunganciphisa ukuqina.
Izici zemvelo nezokugcinwa: Umswakama ophezulu, uthuli oluningi, noma umoya ongemuhle endaweni yokufaka kungathinta isikhathi sokuphila kwe-resistor; ukuntuleka kokugcinwa njalo (njengokungahlanzi umoya ongenayo) kungandisa ingozi yokwehluleka.
Ukuxilongwa kanye nezixazululo yilezi ezilandelayo:
Ukuhlolwa kokuqala: Okokuqala, hlola i-fuse (ngokuvamile etholakala ebhokisini le-fuse ngaphansi konyawo lomshayeli), bese usebenzisa i-multimeter ukukala i-voltage ku-fan plug. Uma ingu-12V kodwa injini ingajikelezi, injini ingase yonakale; uma inani lokumelana elilinganiswa yi-resistor liyi-zero noma lingenamkhawulo, idinga ukushintshwa.
Ukwelashwa okulula: Umsindo ongajwayelekile ungabangelwa izinto zangaphandle ezibhajwe ezinsikeni. Susa ibhokisi lokugcina elingemuva ohlangothini lomgibeli (kudinga izikulufo ezintathu ze-T20), hlanza udoti, bese uthambisa amabheringi. Uma ivolumu yomoya ingajwayelekile, gxila ekuhloleni ukuthi amagiya okuqala, esibili, kanye nawesithathu anenkinga yini.
Isincomo sokufaka esikhundleni: Ngemva kokuqinisekisa iphutha, shintsha i-resistor yokuqala. Lokhu kubiza kancane, kodwa ukusebenza kuhilela isekethe futhi kudinga ukuqaphela. Kunconywa ukuthi iphathwe yisitolo sokulungisa esingochwepheshe ukuze kugwenywe umonakalo wesibili.
Ukulungiswa njalo kunganciphisa ukwenzeka kwamaphutha:
Hlanza njalo uthuli oluvela emoyeni womoya kanye nama-blade omlandeli ukuze uvimbele ukuvaleka.
Hlola ukuthi indawo yokufaka ifeni inomoya omuhle yini ukuze ugweme ukushabalalisa ukushisa okubi.
Gcoba njalo ama-motor bearings bese usebenzisa ama-fuse angempela noma ahambisanayo.
Uma kutholakala ivolumu yomoya noma umsindo ongajwayelekile, kulungise ngokushesha ukuze uvimbele izinkinga ezincane ukuthi zingabi zimbi kakhulu.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
