Kuyini ukumelana kukagesi kwe-blower yemoto?
Ukumelana kukagesi kwe-automotive blower kuyingxenye eyinhloko ye-elekthronikhi ohlelweni lwe-air conditioner yezimoto olulawula ijubane le-blower (fan). Umsebenzi wayo oyinhloko ukufeza ukulungiswa kwamazinga amaningi kwevolumu yokukhipha umoya ye-air conditioner (njengamazinga aphansi, aphakathi, aphezulu amathathu noma ngaphezulu) ngokulawula usayizi wamanje. Isimiso sokusebenza
Ukulawulwa Kwesivinini Sokumelana Kwendabuko: Ezimotweni eziningi zomoya ezisebenzisa umoya ngesandla, ukumelana kwangaphakathi kwenjini yomoya kwakhiwe uchungechunge lwezintambo zokumelana ezihlukaniswe ngezigaba noma ama-resistor e-alloy asekelwe ku-ceramic. Lapho umsebenzisi elungisa igiya lesivinini somoya, isekethe ishintshela ezindleleni ezahlukene zokumelana, ngaleyo ndlela ishintshe ugesi ogeleza ngenjini yomoya. Uma ukumelana kukhulu, ugesi uba mncane, futhi isivinini somoya siba siphansi. Ngokuphambene nalokho, kumagiya aphezulu, ugesi ucishe udlule ukumelana, futhi injini isebenza ngesivinini esigcwele.
Ukulawulwa Kwesivinini se-PWM Yesimanje: Ezinye izimoto ezintsha (ikakhulukazi lezo ezinezinhlelo zomoya opholile ozenzakalelayo) zamukele ubuchwepheshe be-pulse width modulation (PWM). Iyunithi yokulawula umoya opholile ilawula i-voltage ejwayelekile ngama-transistors kagesi (njenge-MOSFET) ukuze kufezwe ukulawulwa kwesivinini okungenasinyathelo. Kodwa-ke, igama elithi "ukumelana nenjini yomoya" lisasetshenziswa kabanzi ukubhekisela kuyo yonke imodyuli yokulawula isivinini somoya.
Ukubonakaliswa Kwephutha Elivamile
Uma ukumelana kwenjini yomoya kuguga noma kungasebenzi kahle, inkomba yephutha ingase ingaqaliswa, kodwa izinkinga ezilandelayo ezijwayelekile zingase zivele:
Akukho moya egiya eliphezulu: Igiya eliphansi noma eliphakathi liyahluleka, futhi ivolumu yomoya ayikwazi ukuncishiswa.
Akukho mpendulo kugiya elithile: Isibonelo, "igiya lesibili" noma "igiya lesithathu" alikhiqizi umoya uma licindezelwa.
Akukho moya nhlobo: Ukumelana kuphukile ngokuphelele, futhi umsinga awukwazi ukudlula.
Ushintsho oluzumayo lwesivinini somoya noma umsindo wokubhonga: Ukuxhumana okungekuhle kwangaphakathi noma ukushiswa kwentambo yokumelana kuholela kugesi ongazinzile.
Izimbangela Zokwehluleka Nokungakwazi Ukuzimela
Ukushiswa kokushisa okuphezulu: Ukumelana kuvame ukuvezwa emazingeni okushisa aphezulu emgudwini womoya wesistimu yokupholisa umoya, futhi izintambo zokumelana noma amalunga e-solder athambekele ekugugeni nasekugugeni.
Ukukhathala kokudlidliza: Ukudlidliza okuqhubekayo ngesikhathi sokusebenza kwemoto kubangela amaphuzu okuxhumana angaphakathi axegayo noma aphukile.
Ukugqwala okumanzi: Ezindaweni eziseningizimu ezinomswakama noma ngemva kokugezwa, umswakama uyangena, usheshise ukubola kwezingxenye zensimbi.
Izinto Nomklamo: Amanye amamodeli amadala (njenge-Audi Q5 B8, i-Buick LaCrosse, i-Kia Sportage, njll.) anomklamo wokuqala wokusabalalisa ukushisa okuncane, futhi izinga lokwehluleka kwezimoto eminyakeni engaphezu kwemi-5 likhuphuka kakhulu.
Izincomo Zokufaka Esikhundleni
Amamojula okuqala noma ahambisanayo: Imikhiqizo yenkampani yangaphandle ingaba namanani wamandla noma okumelana angahambisani, okungenzeka abangele umonakalo wesibili noma ukuthintana okubi.
Ukufakwa okulula: Izimoto eziningi zinezindawo zokuxhumanisa izimoto zangempela ezixhunywe ngqo, ezingadingi ukufakelwa kabusha kwezintambo noma uhlelo.
Hlola ukulandelana: Uma kukhona isivinini somoya esingajwayelekile, kunconywa ukuthi uqale uhlole i-fuse (isb., Volkswagen Passat SC39/SB29), bese ulinganisa inani lokumelana (ibanga elijwayelekile licishe libe ngu-5–15 Ω), bese ekugcineni uhlola injini.
Ukumelana nenjini yomoya kuncane kodwa kuyisici esibalulekile esithinta induduzo ngaphakathi kwemoto. Ukwehluleka kwayo kuvame ukuphambaniswa nokuthi "akukho moya obandayo" noma "ukwehluleka kwenjini," kodwa empeleni kumane kuwukwehluleka ekulawuleni isivinini somoya. Ukushintsha ngesikhathi kungabuyisela ulwazi lokulungisa isivinini somoya olubucayi.
Umsebenzi oyinhloko wokumelana nenjini yomoya yomoya opholile ukulawula ijubane lokujikeleza kwefeni yomoya opholile, ngaleyo ndlela ilawule usayizi wendawo yokukhipha umoya. Isimiso sayo sokusebenza kanye nezici ezihlobene yilezi ezilandelayo:
Umsebenzi Oyinhloko
Lawula isivinini somoya: Ngokushintsha inani lokumelana ukuze kukhawulelwe ugesi ogeleza ngenjini yomoya opholile, kufinyelela izilungiselelo eziningi zesivinini somoya (njengephansi, eliphakathi, eliphezulu, neliphezulu kakhulu).
Ukulawulwa kwezinga lokushisa okusizayo: Nakuba kungalawuli ngqo izinga lokushisa, kuthinta umphumela wokuxubana komoya obandayo noshisayo ngemva kokuthunyelwa, ukuhlanganyela ngokungaqondile ekulawuleni izinga lokushisa. Isimiso sokusebenza
Ezinhlelweni zendabuko zemishini, ukumelana kwenjini yomoya kwakhiwe ngama-resistor amaningi anamanani ahlukene. Uma abasebenzisi bekhetha amagiya ahlukene esivinini somoya, empeleni bashintsha amanani okumelana kusekethe, ngaleyo ndlela bashintsha i-voltage yenjini kanye nesivinini.
Uma usebenzisa igiya lejubane eliphezulu kakhulu (noma ezinhlelweni zomoya opholile ozenzakalelayo), ama-resistor avame ukudlulwa, futhi injini ixhunywe ngqo kugesi, okuthola amandla kagesi aphezulu kanye nesivinini.
Izimoto zanamuhla zisebenzisa kakhulu amamojula okulawula isivinini kagesi (njenge-MOSFET elawulwa yi-PWM), alungisa i-voltage ejwayelekile ngokushintsha umjikelezo womsebenzi wokuguqulwa kobubanzi be-pulse ukuze kufezwe ukulawula isivinini okungenazinyathelo, ngokusebenza kahle okuphezulu kanye nokukhiqizwa kokushisa okuncane.
Ukubonakaliswa kwamaphutha kanye nezindlela zokuvikela
Amaphutha avamile: Ukushiswa ukumelana, ukuncibilika kwefusi, okubangela ukuthi ifeni ingakwazi ukulungisa isivinini, ngokuvamile ishiya igiya eliphezulu kakhulu noma ingajikelezi nhlobo.
Isivikelo esakhelwe ngaphakathi: Ama-resistors amaningi ama-fan ahlanganiswe nama-fuse okushisa. Uma i-fan ibambekile noma ugesi ungajwayelekile, i-fuse iyancibilika ukuze ivimbele ukushisa ngokweqile nomlilo.
Indawo yokufaka: Ngokuvamile iqiniswa emgudwini womoya opholile, kusetshenziswa ukuhamba komoya okuguquguqukayo kwefeni ukuze kuqedwe ukushisa.
Uma isivinini somoya singenakushintshwa, kukhona igiya eliphezulu kakhulu kuphela, noma ifeni ingasebenzi nhlobo, kungenzeka ukuthi i-fan resistor yonakele. Kunconywa ukuthi abasebenzi bokulungisa abangochwepheshe basebenzise i-multimeter ukuyihlola noma ukuyishintsha ukuze bagweme izingozi zesekethe.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
