Irediyetha kawoyela ibizwa nangokuthi i-oil cooler. Iwumshini wokupholisa uwoyela osetshenziswa ezinjinini zikadizili. Ngokwendlela yokupholisa, izinto zokupholisa uwoyela zingahlukaniswa zibe ukupholisa amanzi kanye nokupholisa umoya.
Ngokuvamile, uwoyela wenjini ngokuvamile ubhekisela egameni eliyiqoqo likawoyela wenjini, uwoyela wegiya lezimoto (MT) kanye nowoyela we-hydraulic transmission (AT). Uwoyela we-hydraulic transmission kuphela odinga isipholile samafutha sangaphandle (okungukuthi, irediyetha kawoyela oyishilo). ) ukupholisa okuphoqelekile, ngoba uwoyela we-hydraulic transmission osebenza ekudluliseni okuzenzakalelayo udinga ukudlala indima yokuguqulwa kwe-torque ye-hydraulic, ukuhanjiswa kwe-hydraulic kanye nokugcoba nokuhlanza ngesikhathi esifanayo. Izinga lokushisa elisebenzayo lamafutha okuhambisa nge-hydraulic liphezulu uma kuqhathaniswa. Uma ipholile, ukwenzeka kokukhishwa kwe-ablation kungase kwenzeke, ngakho-ke umsebenzi wokupholisa uwoyela ukupholisa uwoyela wokuhambisa nge-hydraulic ukuze kuqinisekiswe ukuthi ukudluliswa okuzenzakalelayo kungasebenza ngokujwayelekile.
Uhlobo
Ngokwendlela yokupholisa, izinto zokupholisa uwoyela zingahlukaniswa zibe ukupholisa amanzi kanye nokupholisa umoya. Ukupholisa amanzi kuwukwethula isipholile sesekethe yesistimu yokupholisa injini kupholisa uwoyela ofakwe ku-automatic transmission ukuze uphole, noma ukwethula uwoyela ohambisa amanzi nge-hydraulic ekamelweni eliphansi lamanzi kurediyetha wesistimu yokupholisa injini ukuze apholise; Uwoyela ungeniswa ku-oyili opholile ofakwe ohlangothini olubheke umoya lwe-grille yangaphambili ukuze uphole [1].
Umsebenzi Umsebenzi we-radiator kawoyela ukuphoqa uwoyela ukuthi uphole, uvimbele izinga lokushisa likawoyela ukuthi lingabi phezulu kakhulu futhi andise ukusetshenziswa kukawoyela, futhi kuvimbele uwoyela ukuthi ungafaki i-oxidizing futhi uwohloke.
Amaphutha ajwayelekile kanye nezimbangela
Ukwehluleka okuvamile kwamaradiyetha kawoyela apholiselwe ngamanzi asetshenziswayo kuhlanganisa ukugqashuka kwepayipi lethusi, ukuqhekeka kwekhava yangaphambili/engemuva, ukulimala kwe-gasket, nokuvaleka kwangaphakathi kwepayipi lethusi. Ukwehluleka kokugqabuka kweshubhu yethusi kanye nokuqhekeka kwekhava yangaphambili nangemuva ngokuvamile kubangelwa ukwehluleka komsebenzisi ukukhulula amanzi okupholisa ngaphakathi komzimba wenjini kadizili ebusika. Lapho izingxenye ezingenhla zonakalisiwe, kuzoba khona uwoyela endaweni yokupholisa amanzi kanye namanzi okupholisa emafutheni ngaphakathi epanini likawoyela ngesikhathi sokusebenza kwenjini yedizili. Lapho injini ye-diesel isebenza, uma umfutho kawoyela mkhulu kunomfutho wamanzi apholisayo, uwoyela uzongena emanzini okupholisa ngembobo engaphakathi, futhi ngokujikeleza kwamanzi okupholisa, uwoyela uzongena. isipholile samanzi. Lapho injini kadizili iyeka ukujikeleza, izinga lamanzi okupholisa liphezulu, futhi umfutho wawo ungaphezu kwamandla kawoyela. Amanzi okupholisa abulalayo aphumela emafutheni ngembobo engaphakathi, futhi ekugcineni angene epanini likawoyela. Uma u-opharetha engakwazi ukuthola lolu hlobo lwephutha ngesikhathi, njengoba injini ye-diesel iqhubeka nokusebenza, umphumela wokugcoba uwoyela uzolahleka, futhi ekugcineni injini ye-diesel izoba yingozi njengokushiswa kwamathayili.
Ngemuva kokuthi amashubhu ethusi ngamunye ngaphakathi kwe-radiator avinjiwe ngesilinganiso nokungcola, kuzothinta umphumela wokushisa wamafutha kanye nokujikeleza kwamafutha, ngakho kufanele kuhlanzwe njalo.
Ukulungisa kabusha
Ngesikhathi sokusebenza kwenjini ye-diesel, uma kutholakala ukuthi amanzi okupholisa angena epanini likawoyela futhi kukhona amafutha kurediyetha yamanzi, lokhu kwehluleka ngokuvamile kubangelwa ukulimala komnyombo we-cooler yamafutha epholile ngamanzi.
Izindlela zokunakekela eziqondile zimi kanje:
1. Ngemva kokukhipha uwoyela ongcolile ngaphakathi kurediyetha, susa okokupholisa uwoyela. Ngemva kokuba i-cooler ekhishiwe isilinganisiwe, gcwalisa isibandisi ngamanzi ngokusebenzisa indawo yokukhipha amanzi ye-cooler yamafutha. Ngesikhathi sokuhlolwa, indawo yokungena amanzi yayivinjiwe, kanti olunye uhlangothi lwalusebenzisa isilinda somoya esinomfutho ophezulu ukuze kuvuthelwe umoya ngaphakathi kwesipholile. Uma kutholakala ukuthi kukhona amanzi aphuma endaweni yokungena kawoyela kanye ne-outlet ye-radiator yamafutha, kusho ukuthi umgogodla wangaphakathi we-cooler noma indandatho yokuvala yekhava eseceleni yonakele.
2. Susa amakhava angaphambili nangemuva erediyetha yamafutha, bese ukhipha umongo. Uma ungqimba lwangaphandle lomnyombo lutholakala ukuthi lonakalisiwe, lungalungiswa nge-brazing. Uma ungqimba lwangaphakathi lwengqikithi kutholakala ukuthi lonakele, ingqikithi entsha ngokuvamile kufanele ishintshwe noma zombili iziphetho zomongo ofanayo kufanele zivinjwe. Lapho isembozo eseceleni siqhekekile noma siphukile, singasetshenziswa ngemuva kokushisela nge-cast iron electrode. Uma i-gasket yonakalisiwe noma isikhulile, kufanele ishintshwe. Lapho ishubhu yethusi yerediyetha kawoyela epholiswe ngomoya isidayiswa, ngokuvamile ilungiswa ngokubhula.
