Imibhobho yeemoto, njengezona nxalenye ziphambili zoqeqesho lwamandla esithuthi, inkqubo yamafutha, kunye nenkqubo yokupholisa, ichaphazela ngokuthe ngqo ukhuseleko, ukuthembeka, kunye nobomi benkonzo. Njengoko ishishini leemoto lisiya lisiya ekusebenzeni okuphezulu kunye nokukhutshwa kwezinto ezikhutshwayo ezisezantsi, iimfuno zokusebenza kwimibhobho yeauto ziya zisiba nzima. Eli nqaku liza kuphonononga izalathisi eziphambili zokusebenza kunye neendlela zokuphunyezwa kobugcisa bombhobho we-auto ukusuka kwiimbono ezintathu: isayensi yezinto, uyilo lolwakhiwo, kunye nokuguquguquka kokusingqongileyo.
UKhetho lweMathiriyeli Lumisela uMsebenzi oyiNgqondo
Ukuqina kunye nokusebenza kwemibhobho ye-auto kumiselwa ngokukodwa kwiipropati eziphathekayo. Amafutha esintu{1}izithuthi eziqhutywa ngamandla zihlala zisebenzisa intsimbi okanye imibhobho yealuminiyam ukulinganisa amandla kunye neemfuno ezikhaphukhaphu. Ngokuchaseneyo, iinkqubo zokupholisa zoxinzelelo oluphezulu-zezithuthi zamandla amatsha zikholisa ukusebenzisa imihlanganisela yenayiloni okanye imivumbo yentsimbi engatyiwayo ukuze imelane nokuguquguquka okugqithisileyo kwamaqondo kunye nokubola kweekhemikhali. Umzekelo, i-PA66+GF (iglasi-ifayibha{7}}inayiloni eyomeleziweyo) iye yaba lolona khetho luqhelekileyo kwimibhobho ye-injini yombhobho ngenxa yokumelana kwayo nobushushu obuphezulu-({9}}ixesha elide{9}}amaqondo obushushu okusebenza angaphaya kwe-120℃) kunye nokumelana nokungcangcazela. Ngaphaya koko, ubuchwephesha bokugquma bangaphakathi (obufana ne-epoxy resin anti{12}}i-corrosion layers) inokunyusa ukomelela kombhobho ekungeneni kwamafutha kunye ne-oxidation.
Uyilo loLwakhiwo luLungisa uMsebenzi wokuSebenza
Uyilo lwesakhiwo semibhobho kufuneka lulungelelanise ukuguquguquka kwamanzi kunye nokusabalalisa uxinzelelo lomatshini. Multi-izakhelo zemibhobho edityanisiweyo yodonga ephuculwe ngohlalutyo lwento ephelelisiweyo (FEA) yenza iindonga ezibhityileyo (ukunciphisa ukutyeba kodonga nge-15%-}20%) ngelixa kugcinwe amandla oxinzelelo. Umzekelo, -ubushushu obuphezulu bokuphuma kwenkqubo ye-turbocharger isebenzisa inkqubo edityanisiweyo{8}}yentsimbi engenastainless. Umaleko ongaphakathi yichromium ekwaziyo ukumelana nobushushu{11}}ne-nickel alloy, kwaye umaleko wangaphandle uqatywe nge-thermal insulating ceramic coating, ecutha ilahleko yobushushu kwaye ikhusele iingcingo ezijikelezileyo. Uyilo lwetywina lwekhonkco elikhawulezayo lixhomekeke kwizinto ezikhethekileyo ezifana ne-fluororubber (FKM) okanye i-perfluoroelastomer (FFKM) ukuqinisekisa ukusebenza okuvuzayo kumaqondo okushisa asebenzayo ukusuka kwi-40℃ukuya kwi-250 degree.
Ukuguquguquka kokusiNgqongileyo Kuyandisa iMida yeSicelo
Imibhobho yemoto yale mihla kufuneka imelane neemeko zokusebenza ezinzima: uxinzelelo lomoya oluphantsi kwiindawo ezithe tyaba lunokukhokelela kuxinzelelo lomphunga olungaqhelekanga lwepetroli, ukufuma okuphezulu kwimozulu yetropiki kunokukhawulezisa ukuthotywa kwe-electrochemical corrosion of metal parts, kunye neendawo ezibandayo ezigqithisileyo zifuna ukuguquguquka kwemibhobho ukunqanda ukuqhekeka okuncinci. Ukuhlangabezana nezi mfuno, iinjineli zaphuhlisa inkqubo yembuyekezo yembuyekezo{1}}esebenzisa eyakhelweyo{2}}kwimibhobho yokwandiswa kwamalungu ukufunxa ukwanda kwe-thermal kunye nokucutheka, kwaye iqeshe i-nano{3}}iipholima ezilungisiweyo ukomeleza{4}}ubushushu obuphantsi. Idatha yovavanyo ibonisa ukuba i-polytetrafluoroethylene (PTFE) ephathwe ngokukodwa (i-PTFE)- imibhobho enemigca ingagcina ngaphezu kwe-85% yokuguquguquka kwayo kwasekuqaleni nakwi-60 degree.
Kwixesha elizayo, ngokudityaniswa kobuchwephesha bokubeka iliso obukrelekrele, iibhobho ezikrelekrele ezinoxinzelelo oludibeneyo / izinzwa zobushushu ziya kuba ngumkhwa okhulayo. Ixesha lokwenyani{1}ingxelo yedatha ayinikezeli kuphela isilumkiso kwangethuba ngokusilela okunokwenzeka kodwa ikwabonelela ngemilinganiselo ephambili yolawulo olusebenzayo lwamandla esithuthi. Impumelelo eqhubekayo ekusebenzeni kwemibhobho yeemoto ibisoloko isisiseko esibalulekileyo sokwenziwa kwezinto ezintsha zobuchwepheshe bezithuthi.
