I-radiator kawoyela ibizwa nangokuthi i-oil cooler. Iyithuluzi lokupholisa uwoyela elisetshenziswa ezinjinini zedizili. Ngokwendlela yokupholisa, ama-oil cooler angahlukaniswa ngokupholisa amanzi kanye nokupholisa umoya.
Ngokuvamile, uwoyela wenjini ngokuvamile ubhekisela egameni elihlanganisiwe lamafutha enjini, uwoyela wegiya lemoto (MT) kanye nowoyela wokudlulisa we-hydraulic (AT). Uwoyela wokudlulisa we-hydraulic kuphela odinga isiqandisi samafutha sangaphandle (okungukuthi, i-radiator kawoyela oyishilo). ) ukuze kuphole ngokuphoqelekile, ngoba uwoyela wokudlulisa we-hydraulic osebenza ku-automatic transmission udinga ukudlala indima yokuguqulwa kwe-hydraulic torque, ukudluliselwa kwe-hydraulic kanye nokuthambisa kanye nokuhlanza ngesikhathi esifanayo. Izinga lokushisa lokusebenza lamafutha okudlulisa we-hydraulic liphezulu kakhulu. Uma epholile, kungenzeka ukuthi kwenzeke i-ablation ye-transmission, ngakho-ke umsebenzi we-oil cooler ukupholisa uwoyela wokudlulisa we-hydraulic ukuqinisekisa ukuthi ukudluliselwa okuzenzakalelayo kungasebenza kahle.
Uhlobo
Ngokwendlela yokupholisa, ama-oyela apholile angahlukaniswa ngokupholisa amanzi kanye nokupholisa umoya. Ukupholisa amanzi kuwukufaka i-coolant ku-circuit yesistimu yokupholisa injini ku-oyela apholile afakwe ku-transmission ezenzakalelayo ukuze kuphole, noma ukufaka i-hydraulic transmission oil ekamelweni lamanzi elingezansi le-radiator yesistimu yokupholisa injini ukuze kuphole; I-oyela ifakwa ku-oyela apholile afakwe ohlangothini olubheke phezulu lwe-grille yangaphambili ukuze kuphole [1].
Umsebenzi Umsebenzi we-radiator kawoyela ukuphoqa uwoyela ukuthi uphole, ukuvimbela izinga lokushisa likawoyela ukuthi lingabi phezulu kakhulu nokwandisa ukusetshenziswa kukawoyela, kanye nokuvimbela uwoyela ukuthi ungabi yi-oxidi futhi ubole.
Amaphutha avamile nezimbangela
Ukwehluleka okuvamile kwama-radiator kawoyela apholile ngamanzi asetshenziswayo kufaka phakathi ukuqhekeka kwepayipi lethusi, ukuqhekeka kwesembozo sangaphambili/sangemuva, ukulimala kwe-gasket, kanye nokuvaleka kwangaphakathi kwepayipi lethusi. Ukwehluleka kokuqhekeka kwepayipi lethusi kanye nokuqhekeka kwesembozo sangaphambili nangemuva kubangelwa kakhulu ukwehluleka komqhubi ukukhipha amanzi okupholisa ngaphakathi komzimba wenjini yedizili ebusika. Lapho izingxenye ezingenhla zonakele, kuzoba khona uwoyela esiqandisini samanzi kanye namanzi okupholisa emafutheni ngaphakathi kwepani likawoyela ngesikhathi sokusebenza kwenjini yedizili. Lapho injini yedizili isebenza, uma ingcindezi kawoyela inkulu kunokucindezela kwamanzi okupholisa, uwoyela uzongena emanzini okupholisa ngembobo esenkabeni, futhi ngokujikeleziswa kwamanzi okupholisa, uwoyela uzongena esiqandisini samanzi. Lapho injini yedizili iyeka ukujikeleza, izinga lamanzi okupholisa liphezulu, futhi ingcindezi yawo inkulu kunokucindezela kawoyela. Amanzi okupholisa abulalayo aphuma angene emafutheni ngembobo esenkabeni, bese ekugcineni angene epanini likawoyela. Uma umqhubi engakwazi ukuthola lolu hlobo lwephutha ngesikhathi, njengoba injini kadizili iqhubeka nokusebenza, umphumela wokugcoba kawoyela uzolahleka, futhi ekugcineni injini kadizili izoba nengozi njengokushiswa kwamathayela.
Ngemva kokuba amapayipi ethusi ngalinye ngaphakathi kwe-radiator evinjiwe yisilinganiso kanye nokungcola, kuzothinta umphumela wokushabalalisa ukushisa kwamafutha kanye nokugeleza kwawo, ngakho-ke kufanele ahlanzwe njalo.
Ukulungiswa kabusha
Ngesikhathi sokusebenza kwenjini kadizili, uma kutholakala ukuthi amanzi okupholisa angena epanini likawoyela futhi kukhona uwoyela kurediyetha yamanzi, lokhu kwehluleka ngokuvamile kubangelwa umonakalo engxenyeni engaphakathi yesiqandisi sikawoyela esipholile ngamanzi.
Izindlela ezithile zokulungisa yilezi ezilandelayo:
1. Ngemva kokukhipha uwoyela ongcolile ngaphakathi kwerediyetha, susa ifriji yamafutha. Ngemva kokuba ifriji esusiwe isilinganisiwe, gcwalisa ifriji ngamanzi ngokusebenzisa indawo yokuphuma kwamanzi yefriji yamafutha. Ngesikhathi sokuhlolwa, indawo yokungena yamanzi yavalwa, kanti olunye uhlangothi lusebenzise isilinda somoya esinomfutho ophezulu ukuze lufutha ingaphakathi lefriji. Uma kutholakala ukuthi kunamanzi aphuma endaweni yokungena yamafutha kanye nendawo yokuphuma yerediyetha yamafutha, kusho ukuthi ingaphakathi lefriji noma indandatho yokuvala yesembozo esiseceleni yonakele.
2. Susa izembozo zangaphambili nezangemuva ze-radiator kawoyela, bese ukhipha i-core. Uma ungqimba lwangaphandle lwe-core lutholakala lonakele, lungalungiswa ngokufaka i-brazing. Uma ungqimba lwangaphakathi lwe-core lutholakala lonakele, i-core entsha ngokuvamile kufanele ishintshwe noma zombili iziphetho ze-core efanayo kufanele zivinjwe. Uma isembozo esiseceleni siqhekekile noma siphukile, singasetshenziswa ngemuva kokushisela nge-electrode yensimbi ephosiwe. Uma i-gasket yonakele noma igugile, kufanele ishintshwe. Uma ithubhu yethusi ye-radiator kawoyela epholiswe ngomoya isuswa ekushiseni, ngokuvamile ilungiswa ngokufaka i-brazing.
