Kwiinkqubo zokupholisa iimoto ezine-fan drive yombane, ifeni iyacinywa kwaye icinywe ngokuzenzekelayo xa ubushushu bokupholisa buguquka.Indima ephambili kwinkqubo idlalwa yi-fan turn on sensor - unokufunda yonke into malunga neli candelo kule nqaku.
Yintoni isivamvo sokutshintsha kwefeni?
I-fan switch-on sensor sisixhobo sombane okanye i-electromechanical kunye neqela loqhagamshelwano (amaqela) elivala okanye livula isiphaluka sombane ngokuxhomekeke kwiqondo lokushisa.I-sensor ifakwe kwisekethe yonikezelo lwamandla okanye ulawulo lokuqhuba kombane we-injini yokupholisa inkqubo, yinto enovakalelo enika uphawu lokuvula okanye ukucima i-fan ngokuxhomekeke kubushushu besipholisi (coolant) .
Ezi zivamvo zisetyenziswa kuphela kwizithuthi ezineefeni zokupholisa zeradiyetha eziqhutywa ngombane.Iifeni eziqhutywa yi-injini ye-crankshaft zivulwa kwaye zicinywe ngokusebenzisa i-clutch ye-viscous okanye ngezinye iindlela ezingaqwalaselwanga apha.
Iindidi ze-fan switch-on sensors
Zonke izinzwa zefeni zohlulwe zibe ngamaqela amabini ngokomgaqo wokusebenza:
•Electromechanical;
•Ngombane.
Ngokulandelayo, i-electromechanical sensors zohlulwe zibe ziindidi ezimbini:
• Ngento yokuva esekelwe kulwelo olusebenzayo kunye ne-coefficient ephezulu yokwandiswa (i-wax);
• Ngento yokuva esekelwe kwi-bimetallic plate.
Ngenxa yeempawu zoyilo, iisensom ze-electromechanical zinokudityaniswa ngokuthe ngqo kwisekethe yonikezelo lwamandla ombane (nangona ngokufuthi i-sensor ifakiwe kwisekethe ye-fan relay), kwaye iisenso ze-elektroniki zinokudityaniswa kuphela kwisekethe yokulawula i-fan drive.
Kwakhona, abenzi boluvo be-electromechanical bahlulahlulwe baziindidi ezimbini ngokwenani lamaqela oqhagamshelwano:
• Isantya esisodwa - sibe neqela elinye loqhagamshelwano, elivala kwiqondo elithile lobushushu;
• Isantya-ezimbini - ube namaqela amabini oqhagamshelwano avale kumaqondo obushushu ahlukeneyo, nto leyo ekuvumela ukuba utshintshe isantya sefeni ngokuxhomekeke kubushushu bokupholisa.
Kule meko, amaqela oqhagamshelwano anokuba kwelinye lamazwe amabini: ngokuqhelekileyo avule kwaye avalwe ngokuqhelekileyo.Kwimeko yokuqala, umqhubi uvula xa abafowunelwa bevaliwe, okwesibini - xa bevula (iisekethe zokulawula ezongezelelweyo zingasetyenziswa apha).
Okokugqibela, abenzi boluvo bahluke kwiqondo lobushushu elivuliweyo labalandeli.Kwizixhobo zasekhaya, izithuba ze-82-87, 87-92 kunye ne-94-99 ° C zinikezelwa, kwizixhobo zangaphandle amaxesha okushisa alala malunga nemida efanayo, ahluke enye ukuya kwiidigri ezimbini.
Uyilo kunye nomgaqo wokusebenza kwenzwa ye-electromechanical nge-wax
Olu lolona hlobo luqhelekileyo lwabenzi boluvo lwefeni.Isiseko senzwa sisitya esizaliswe nge-petroleum wax (i-ceresite, iqulethe ubukhulu becala iparafini) kunye ne-admixture of copper powder.Isitya esine-wax sivalwe nge-membrane eguquguqukayo apho i-pusher ibekwe khona, ixhunywe kwindlela yokuqhuba uqhagamshelwano oluhambayo.I-drive yoqhagamshelwano ingaba ngqo (usebenzisa i-pusher efanayo) okanye ngokungathanga ngqo, usebenzisa i-lever kunye nentwasahlobo (kule meko, ukuvalwa okuthembekileyo kunye nokuvulwa kwesekethe kufezekiswa).Zonke iindawo zifakwe kwi-case yensimbi engqingqwa (oku kubonelela ngokufudumeza okufanayo kolwelo olusebenzayo) kunye nentambo kunye nesixhumi sombane.
Umgaqo wokusebenza kwenzwa enjalo isekelwe kwimpembelelo yokutshintsha umthamo we-fluid esebenzayo xa iqondo lokushisa litshintsha (likwasetyenziswa kwii-thermostats zemoto).I-Wax, edlala indima yolwelo olusebenzayo kwi-sensor, ine-coefficient enkulu yokwandiswa kwe-thermal, xa ishushu, iyanda kwaye iyasuswa kwisitya.I-wax eyandisiweyo iphumla kwi-membrane kwaye ibangela ukuba iphakame - oko, ihambisa i-pusher kwaye ivale abafowunelwa - i-fan ivula.Xa iqondo lokushisa lihla, i-membrane iyancipha kwaye abafowunelwa bavule - i-fan iyacima.
I-sensor-speed sensors zisebenzisa, ngokulandelanayo, ii-membrane ezimbini kunye noqhagamshelwano oluhambahambayo, olubangelwa ngamaxesha ahlukeneyo okushisa.
I-sensor ifakwe kwi-radiator yokupholisa (ngokusebenzisa i-gasket yokutywina), inxalenye yayo yokusebenza idibene ngokuthe ngqo ne-coolant, apho i-fluid esebenzayo ishushu.Ngokwesiqhelo, imoto isebenzisa isivamvo sefan enye, kodwa namhlanje unokufumana izisombululo kunye nezinzwa ezimbini ezinesantya esinye ezibekwe kumaqondo obushushu ahlukeneyo.
Uyilo kunye nomgaqo wokusebenza kwenzwa kunye ne-bimetallic plate
Kukho iintlobo ezininzi zeenzwa zolu hlobo, kodwa ngokubanzi, uyilo lwazo lulula kakhulu.Isiseko senzwa yiplate ye-bimetallic yesimo esinye okanye enye, apho umnxibelelwano ohambayo ukhona.Kusenokubakho amacandelo ancedisayo kwi-sensor yokuvalwa koqhagamshelwano oluthembekileyo.I-plate ifakwe kwi-case yensimbi etywiniweyo, enika intambo kunye nesixhumi sombane sokudibanisa kwinkqubo yokulawula i-fan.
Umgaqo wokusebenza kwenzwa usekelwe kwi-phenomenon of deformation ye-bimetallic plate xa ubushushu buguquka.Ipleyiti ye-bimetallic ziipleyiti ezimbini zetsimbi ezidityaniswe omnye komnye ezinama-coefficients ahlukeneyo okwandiswa kwe-thermal.Njengoko iqondo lokushisa liphakama, iintsimbi zanda ngeendlela ezahlukeneyo, ngenxa yoko, i-bimetallic plate igoba kwaye ihambisa umnxeba oshukumayo - isiphaluka siyavala (okanye sivule kunye nabafowunelwa abaqhelekileyo abavaliweyo), i-fan iqala ukujikeleza.
Umdibaniso woluvo uyafana nale ichazwe ngasentla.Iinzwa zolu hlobo zincinci ziqhelekileyo ngenxa yexabiso labo eliphezulu kunye nobunzima.
Uyilo kunye nomgaqo wokusebenza kwenzwa ye-elektroniki
Ngokwesakhiwo, le sensor nayo ilula kakhulu: isekwe kwi-thermistor ebekwe kwityala elikhulu lentsimbi kunye nentambo yokujija kwiradiyetha kunye nesinxibelelanisi sombane.
Umgaqo wokusebenza kwenzwa usekelwe kwimpembelelo yokutshintsha ukuchasana kombane we-thermistor xa ubushushu buguquka.Ngokuxhomekeke kuhlobo lwe-thermistor, ukuchasana kwayo kunokuncipha okanye ukunyuka ngokunyuka kweqondo lokushisa.Utshintsho ekuchaseni kwe-thermistor lujongwa yisekethe ye-elektroniki, ethi, xa iqondo lokushisa elithile lifikeleleke, lithumela iimpawu zokulawula ukuvula, ukuguqula isantya sokujikeleza okanye ukucima umqhubi.
