Iyini injini yomshini wokugcwalisa ibhodlela lemoto?
Injini yomshini wokuphefumula wezimoto iyisici esiyinhloko sokushayela ohlelweni lokupholisa umoya noma lokushisa lwemoto, esebenza ngokuyinhloko ukukhiqiza ukugeleza komoya ukulawula izinga lokushisa, umswakama, kanye nekhwalithi yomoya ngaphakathi emotweni.
Isimiso sokusebenza kanye nesakhiwo: Injini iguqula amandla kagesi abe amandla omshini ukuze ishayele i-rotor noma ama-blade ukuze ajikeleze, idonse umoya bese iwusunduza ohlelweni lokungenisa umoya ngaphambi kokuwuyisa ezindaweni zokuphuma. Ijubane layo lingalawulwa ngokulungisa ukumelana kwesekethe ukuze kufezwe ukulawulwa kwesivinini esiningi, ngaleyo ndlela kushintshwe ivolumu yomoya.
Indawo kanye nokuhlanganiswa: Injini ivame ukufakwa ngaphambili kwemoto eduze kwegumbi lenjini, ihlanganiswe nezingxenye ezifana ne-evaporator yomoya opholile kanye ne-heater core, okwakha uhlelo lokufudumala, ukungenisa umoya, kanye nokupholisa umoya (i-HVAC). Ezimotweni zikagesi, ihlanganiswa ngokujulile nezinhlelo zepompo yokushisa, ukuphathwa kokushisa kwebhethri, njll., okuba yingxenye ebalulekile yesistimu yokuphatha ukushisa yemoto.
Ukuvela kobuchwepheshe kanye nokwandiswa komsebenzi: Ama-motor e-DC abhulashiwe endabuko athathelwa indawo kancane kancane ngama-motor e-DC angenamabhulashi (BLDC) ukuze kuthuthukiswe ukusebenza kahle, kuncishiswe umsindo, futhi kuhlangatshezwane nezidingo zama-cabin ahlakaniphile okulawula izinga lokushisa lendawo kanye nokulawula izwi. Ngesikhathi esifanayo, kudingeka futhi isebenze ngokubambisana ne-module yokuhlanza umoya (njengezihlungi ze-HEPA), isebenza ngokuqina ngaphansi kwengcindezi ephezulu engaguquki kanye nezimo zomsindo ophansi ukuze kuthuthukiswe ikhwalithi yomoya wangaphakathi.
Injini yomshini wokuphefumula wezimoto iyisici esiyinhloko sohlelo lokupholisa umoya, esinomthwalo wokuqhuba i-rotor ukuthi ijikeleze futhi ikhiqize ukugeleza komoya ukuze kulawulwe imvelo yangaphakathi.
Imisebenzi yayo eyinhloko ihlanganisa: Okokuqala, ukulawula izinga lokushisa langaphakathi ngokufutha umoya obandayo (ovela ku-evaporator) noma umoya ofudumele (ovela ku-water heater) ungene ekhabini, wehlise noma uphakamise izinga lokushisa ngokushesha futhi uthuthukise induduzo; okwesibili, ukukhuthaza ukujikeleza komoya, ukusekela ukujikeleza kwangaphakathi (ukujikeleza kabusha komoya wangaphakathi) kanye nokujikeleza kwangaphandle (ukwethula umoya omusha ovela ngaphandle), ukuthuthukisa ikhwalithi yomoya kanye nokunciphisa uthuli; ngaphezu kwalokho, ukusiza ekususeni umswakama kanye nokususa umswakama, ukusiza ekususeni inkungu yamafasitela esimweni sezulu esinomswakama, ukuthuthukisa ukuphepha; ekugcineni, ukufeza ukulawula ivolumu yomoya ngokulungisa isivinini semoto (njengokulawulwa kwesivinini esiningi) ukushintsha ivolumu yomoya ngokwezidingo ezahlukene.
Ngokuphathelene nesimiso sokusebenza, ngemva kokusetshenziswa, injini iqhuba i-rotor ukuze ijikeleze, isebenzisa amandla e-centrifugal ukudonsa umoya bese iwuqondisa ebhokisini lomoya opholile, lapho ivolumu yomoya ilawulwa yi-voltage yokufaka noma i-resistor yokulungisa isivinini. Izimoto zanamuhla zingahlanganisa nezindlela ezizenzakalelayo, zilungise ngokuhlakanipha isivinini ngokusekelwe kudatha yenzwa.
Uma injini yomshini wokuphefumula ihluleka, izimpawu ezivamile zifaka phakathi umshini wokuphefumula ongaphenduki nhlobo, ojika kancane, noma onomsindo ongajwayelekile (njengomsindo "wokubhonga"), okuholela ekungangeni komoya noma ukungasebenzi kahle komoya ovela ohlelweni lokupholisa umoya noma lokushisa.
Izimbangela zokwehluleka ziyahlukahluka, ikakhulukazi ezihilela izinkinga zemishini, zesekethe, kanye nezemoto. Izici zemishini zifaka phakathi ukuqongelela uthuli kuma-bearings e-rotor ngokuhamba kwesikhathi, ukwandisa ukungqubuzana futhi kubangele ukuthi i-rotor ijame noma i-coil ishise kakhulu futhi yonakalise; izikulufu ezikhululekile phakathi kwemoto kanye ne-fan blade nazo zingavimbela imoto ekushayeleni i-fan blade. Izinkinga zesekethe zifaka phakathi ama-short circuits ezintanjeni zikagesi, ukuthintana okubi, ama-fuse aqhumile, ukwehluleka kokudlulisela, noma ama-control switch alimele, okungaphazamisa ukunikezwa kwamandla; ukwehluleka kwe-capacitor (njengokwanele komthamo noma ukuvuza) kungathinta ukuqala kwemoto. Ukwehluleka kwemoto okuqondile njengama-coil ashisiwe, ama-windings aphukile noma ama-short-circuited angaholela ngqo ekuhlulekeni.
Ngesikhathi sokuxilongwa, umuntu angaqala ahlole izinkinga zesekethe eziyisisekelo, bese ebhekana nenjini. Isibonelo, ukuhlola ukuthi i-fuse ivuthelwe yini, ukuqinisekisa ukuxhumana okufanele kwezintambo zikagesi, uma ukunikezwa kukagesi kulungile kodwa injini ingaphenduki futhi inomsindo "wokubhodla", kungaba ukwehluleka kwe-capacitor okudinga ukushintshwa; nge-rotor evinjiwe, ngemva kokucima ugesi, zama ukuconsa uwoyela wokugcoba ku-bearing bese uhambisa i-fan blade. Uma lezi zindlela zingasebenzi, ngokuvamile kudingeka ukushintshwa kwenjini noma ukulungiswa.
