Umgaqo wokusebenza we-blower motor resistor
I-resistor ye-blower motor ilawula isantya se-blower motor ngokutshintsha ubungakanani bangoku, ngaloo ndlela ilawula isantya somoya opholileyo. Ngokwenyani, yi-resistor eguquguqukayo ethintela umbane ngokunyusa okanye ukunciphisa ixabiso lokuxhathisa, ifezekisa utshintsho ukusuka kwisantya esiphantsi ukuya kwisantya esiphezulu. Nantsi ingcaciso eneenkcukacha:
I-resistor ilawula njani isantya somoya?
Umbindi we-blower motor resistor kukuthintela ukuhamba komsinga. Okukhona umsinga umncinci, kokukhona i-blower motor ijikeleza kancinci; okukhona umsinga umkhulu, kokukhona ujikeleza ngokukhawuleza. Ngokukodwa, yahlulwe yangamanyathelo amathathu:
Isantya somoya esiphantsi (njengegiya yoku-1): Umbane udlula kwii-resistor ezininzi zochungechunge (ngesiqhelo zi-3), ixabiso lokumelana lelona likhulu, umbane ngowona mncinci, kwaye i-blower motor ijikeleza ngesantya esiphantsi.
Isantya somoya esiphakathi (njengegiya yesibini ukuya kweyesithathu): Umsinga udlula kwiiresistor ezimbalwa (2 okanye 1), ixabiso lokumelana liyancipha, umsinga uyanda, kwaye i-blower motor ikhawuleza.
Isantya somoya esiphezulu (njengegiya yesi-4): Umbane udlula ii-resistor kwaye unikezelwa ngokuthe ngqo, ixabiso lokumelana lisondele ku-zero, umbane ngowona mkhulu, kwaye i-blower motor ijikeleza ngesantya esipheleleyo.
Yintoni umahluko phakathi kweendlela zokulawula zemveli nezanamhlanje?
Ulawulo lwe-resistor yendabuko: Ixhomekeke kwiiswitshi ezibonakalayo ukutshintsha indibaniselwano ye-resistor. Umzekelo, iqhosha elikwiphaneli ye-air conditioner likhetha ngokuthe ngqo inani le-resistor zochungechunge, nto leyo elula kodwa engasebenzi kakuhle (inxalenye yamandla ombane iguqulwa ibe bubushushu kwaye ichithwe).
Ulawulo lwe-PWM lwanamhlanje: Lusetyenziswa rhoqo kwiimoto ezintsha ukuze luhlengahlengiswe ngemiqondiso ye-pulse (PWM). Itshiphu yekhompyutha yomoya opholileyo ithumela imiqondiso yokulawula ixesha lokuvula kweswitshi zamandla (ezifana neeMOSFET), itshintsha ngokungathanga ngqo i-voltage kunye nesantya sokuphuma, nto leyo echanekileyo ngakumbi kwaye igcina amandla.
Kuza kwenzeka ntoni ukuba i-resistor yaphuka?
Ukuba i-resistor iyatsha okanye ayidibani kakuhle, i-blower motor inokusebenza kuphela kwigiya ephezulu (i-current straight through) okanye ingabi nomoya konke konke (i-fuse breated).
I-resistor ye-blower motor etshisiweyo ingalungiswa, kodwa kudla ngokucetyiswa ukuba itshintshelwe entsha kuba ingatsha kwakhona okanye ibe nobungozi bokhuseleko emva kokulungiswa. Nantsi uhlalutyo oluthile kunye nengcebiso:
Indlela yokulungisa (kwimeko engxamisekileyo kuphela)
Ukuba i-resistor itshiswe kancinci (njengokuba i-solder joint ikhululeka), ungazama ukuyilungisa:
Ukusebenza kokucima umbane: Okokuqala qhawula isiphelo sebhetri yemoto ukuze uphephe iingozi ze-short circuit.
Shicilela i-solder joint ekhululekileyo: Sebenzisa i-soldering iron kunye ne-solder ukuze uqhagamshelane kwakhona ne-copper sheet ye-resistor, kwaye uyicinezele ngokuqinileyo ngaphambi kokuba iphole (kungenjalo i-solder ingabhabha).
Vavanya isiphumo: Emva kokufaka kwakhona, qalisa i-air conditioner kwaye ujonge ukuba umthamo womoya wegiya ukusuka ku-1 ukuya ku-3 ubuyiselwe na.
Qaphela: I-resistor elungisiweyo ingatsha kwakhona ngenxa yokwaluphala okanye iingxaki zokuchitha ubushushu, kwaye ukusebenza okungafanelekanga kunokonakalisa isekethe.
Kutheni kucetyiswa ukuba kutshintshwe i-resistor entsha?
Ikhuselekile kwaye ithembekile: I-resistor elungisiweyo idla ngokubuyela kwiimpazamo, ngelixa ukutshintsha inxalenye entsha kunokusombulula ingxaki ngokupheleleyo.
Ukusebenza okulula: Kwiimodeli ezininzi, i-resistor ikwindawo engasemva kwebhokisi yeglavu yomkhweli, kwaye ingatshintshwa ngokususa izikrufu ezimbini (kuthatha malunga nemizuzu engama-30).
Ukuphepha umonakalo onxulumene noko: Ukutsha kwe-resistor kudla ngokubangelwa kukumelana kakhulu kwe-motor. Ukungayitshintshi i-resistor entsha kunokonakalisa i-blower motor okanye i-fuse.
Yenza ivenkile yobugcisa okanye yeyokwenza izinto ngokwakho?
Iimeko zokuzenzela: Kufuneka ulungiselele isikrufu se-Allen kunye nentsimbi yokugalela (kubasebenzisi abanamava kuphela), kwaye ujonge ividiyo yokulungisa imodeli yakho.
I-resistor ye-blower motor yinxalenye ebalulekileyo kwinkqubo yomoya opholileyo yemoto elawula isantya se-blower motor. Ukungasebenzi kwayo kuya kuchaphazela ukusetyenziswa okuqhelekileyo kwe-air conditioner. Oku kulandelayo kusekelwe kwiimeko eziqhelekileyo.
Iimpawu eziphambili zokungaphumeleli kwe-blower motor resistor ziquka:
Ulawulo olungaqhelekanga lomthamo womoya: Uphawu oluqhelekileyo kukungabikho komoya okanye umoya obuthathaka kwiigiya ezinesantya esiphantsi (ezifana negiya yoku-1, eyesi-2, neyesi-3), ngelixa igiya enesantya esiphezulu (igiya yesi-4) iqhelekile. Oku kungenxa yokuba iigiya ezinesantya esiphantsi zifumana ulawulo lwesantya ngokwahlulahlula i-resistor voltage, kwaye xa i-resistor yonakele, ayinakutshintsha iigiya, nto leyo ebangela ukungakwazi ukulungisa umthamo womoya okanye umthamo womoya ofanayo kuzo zonke iigiya.
Imoto evuthelayo ayisebenzi okanye ayisebenzi ngendlela engaqhelekanga: Isenokubonakala njengemoto engajikeleziyo, ukujikeleza okucothayo, ukuqala okunzima, okanye ehamba nezandi ezingaqhelekanga (ezifana nokudumzela okanye ukucofa), okuhlala kunxulumene nokutsha kwe-resistor, ukuguguleka kweebheringi, okanye izinto zangaphandle ezinamathele kwiiblade.
Iingxaki ezinxulumene nenkqubo: Kwiimeko ezigqithisileyo, ukungaphumeleli kwe-resistor kunokubangela ukugcwala kwesekethe, okukhokelela ekuqhumeni kwe-fuse, impazamo ye-ECU, okanye ukukhanya kwe-injini.
Izizathu eziphambili zokungaphumeleli ziquka: Umonakalo wobushushu obugqithisileyo: Ukuba i-resistor isebenza ixesha elide ngaphandle kokuchithwa kobushushu ngokufanelekileyo, okanye ukuba i-fan bearing iyaguga okanye uthuli luqokelelana kwiiblades, nto leyo enyusa ukumelana kwaye ibangele umbane ogqithisileyo, i-resistor inokutshisa kakhulu kwaye itshise.
Umbane ongaqhelekanga: Ukungasebenzi kakuhle kwenjini yefeni (njengokuxinana kwangaphakathi okanye ukuwohloka kwengalo) kunokubangela umbane ogqithisileyo, okukhawulezisa ukuguga kwe-resistor; iinkcukacha zefuse ezingalunganga okanye ii-short circuit circuit nazo zinokubangela ukunyuka okungaqhelekanga.
Imiba yomgangatho we-resistor ngokwayo: Amandla angonelanga, umgangatho ophantsi wezinto, okanye ukuwelda okukhululekileyo (njengee-solder joints ezikhululekileyo) kunokunciphisa ukuqina.
Izinto ezichaphazela imeko-bume kunye nokugcinwa kwayo: Ukufuma okuphezulu, uthuli oluninzi, okanye umoya ongekho mgangathweni kwindawo efakelwe kuyo kunokuchaphazela ubomi be-resistor; ukungabikho kokugcinwa rhoqo (njengokungacoci indawo yokungenisa umoya) kunokunyusa umngcipheko wokungasebenzi kakuhle.
Uxilongo kunye nezisombululo zezi zilandelayo:
Uhlolo lwangaphambili: Okokuqala, jonga i-fuse (edla ngokuba kwibhokisi ye-fuse phantsi konyawo lomqhubi), uze usebenzise i-multimeter ukulinganisa i-voltage kwi-fan plug. Ukuba yi-12V kodwa i-motor ayijikelezi, i-motor ingonakala; ukuba ixabiso lokuxhathisa elilinganiswe yi-resistor liyi-zero okanye alinasiphelo, kufuneka itshintshwe.
Unyango olulula: Ingxolo engaqhelekanga inokubangelwa zizinto zangaphandle ezinamathele kwiiblade. Susa ibhokisi yokugcina engasemva kwicala lomkhweli (kufuneka izikrufu ezintathu ze-T20), coca inkunkuma, kwaye uthambise iibheringi. Xa umoya ungalingani, gxila ekujongeni ukuba iigiya zoku-1, ezesi-2, nezesi-3 zineempazamo.
Ingcebiso yokutshintsha: Emva kokuqinisekisa impazamo, tshintsha i-resistor yokuqala. Oku kubiza kancinci, kodwa umsebenzi ubandakanya isekethe kwaye ufuna unonophelo. Kucetyiswa ukuba iphathwe yivenkile yokulungisa yobungcali ukuze kuthintelwe umonakalo wesibini.
Ukugcinwa rhoqo kunokunciphisa ukwenzeka kweziphene:
Hlamba rhoqo uthuli oluvela kumoya wefeni kunye neencakuba ukuze uthintele ukuvaleka.
Jonga ukuba indawo yokufaka ifeni inomoya ofanelekileyo na ukuze kuthintelwe ukusasazwa kobushushu okungalunganga.
Lungisa rhoqo iibheringi zeemoto kwaye usebenzise iifusi zoqobo okanye ezihambelanayo.
Ukuba kufunyenwe umoya ongaqhelekanga okanye ingxolo, yilungise ngokukhawuleza ukuze uthintele iingxaki ezincinci ukuba zingabi mbi.
