Kuthetha ukuthini ukuqhekeka kwesitshixo somoya?
Ukuqhawuka kwesitshixo somoya kubhekiselele kwimeko apho ivalve ye-injini iqhekeziwe okanye yaphukile. Le meko idla ngokubangelwa zizinto ezahlukeneyo, kubandakanywa isiphelo sentonga yevalve, isikrufu sohlengahlengiso okanye ukunxiba kwengalo yerocker okanye uhlengahlengiso olungafanelekanga, okukhokelela ekukhutshweni kwevalve okugqithisileyo, nto leyo ebangela ukuba ivalve tappet iphele ukuba ingqubane nesikrufu sohlengahlengiso okanye intloko. yengalo yevalve yeroki ukungqubana nesiphelo sevalve, nto leyo enokuthi ekugqibeleni ikhokelele ekuqhekekeni kwevalve. Ukongeza, ukunxiba okugqithisileyo kwe-CAM, i-valve spring seat off, i-valve tappet yokulungisa i-nati ekhululekile okanye yokulungelelanisa ubuso obungalinganiyo, i-valve duct carbon accumulation kunye nezinye izinto zinokukhokelela ekuqhekekeni kwevalve. Ukuze ugweme ezi ngxaki, kuyimfuneko ukujonga nokugcina injini rhoqo ukuqinisekisa ukusebenza okuqhelekileyo kwamacandelo ahlukeneyo.
Ngaba iblade yokutshixa umoya?
Ipleyiti yokutshixa ucango lomoya yinxalenye, indima yayo kukuqonda uqhagamshelo lwendlela enye phakathi kwevalve kunye nesitulo sasentwasahlobo kwaye uyitshixe ukuqinisekisa ukuba ivelufa ingasebenza ngokuqhelekileyo. Nangona kunjalo, xa ipleyiti yokuvala ivalve ingaphumeleli, iya kuba nefuthe elikhulu kwi-injini. Ngokomzekelo, ipleyiti yokutshixa inokubangela ukuba ivalve ivaleke ngokukhululekileyo, nto leyo ebangela ukuba umlinganiselo wokucinezelwa ungonelanga, emva koko ubangele ukuba injini ilahlekelwe sisilinda. Kwiimeko ezinzima, ilahleko yepleyiti yokutshixa inokubangela ukuba ipiston ibethelwe ngevalve, ize iyilahle injini.
Kukho iindlela ezimbini zokudibanisa i-valve stem entwasahlobo. Olunye luhlobo lwekliphu yokutshixa, exhotyiswe ngeziqephu ezibini zesiqingatha sesetyhula ezitshixayo kumjelo wesiphelo sentonga yevalvu, kwaye isihlalo sasentwasahlobo sidibanisa ikliphu yokutshixa ukuze ihupula eqinileyo ikwisiphelo sentonga yevalvu. , ukwenzela ukuba isihlalo sasentwasahlobo, ikliphu yokukhiya kunye nevalve idibaniswe ngokupheleleyo, kwaye i-valve ihamba kunye. Enye indlela kukusebenzisa iphini lokutshixa endaweni yomngxuma weradial wephini lokuvala, kwaye uqhagamshele ngephini lokutshixa.
Zeziphi izizathu eziphambili zokuqhekeka kwevalvu?
Ezona zizathu ziphambili zokuqhekeka kwevalve zibandakanya ukunxiba okungafanelekanga okanye ukulungiswa, ukunxiba kwe-CAM, i-valve spring seat off, i-nati ekhululekileyo okanye i-bolt end face engalinganiyo, i-valve duct carbon accumulation. ...
Ukunxiba okungafanelekanga okanye uhlengahlengiso: Ukunxiba okungafanelekanga okanye uhlengahlengiso lwentonga yevalve, isikrufu sokulungelelanisa, okanye ingalo ye-rocker inokubangela ukukhutshwa okugqithisileyo kwevalve, okunokubangela ukuba isiphelo setappet yevalve esecaleni ingqubane nesikrufu sokulungelelanisa, okanye intloko. yengalo yerocker yevalve engaphezulu ukungqubana nesiphelo sevalve, okukhokelela ekuqhekekeni kwevalve.
Ukugqoka kwe-CAM : Ukugqithisa ngokugqithiseleyo kwe-CAM kunokubangela ukuba i-tappet ijite ngexesha lokusebenza, okuya kwandisa uxinzelelo lwentonga yevalve kwaye kunokukhokelela ekuqhekekeni kwevalve ekuhambeni kwexesha.
Ivalve spring seat off : Ukuwa kwevalve spring seat kunokubangela ukuba ivalve ibe phantsi kwempembelelo engaqhelekanga ngexesha lenkqubo yokuvala, okukhokelela ekuqhekekeni.
I-nati ekhululekileyo okanye ubuso obungalinganiyo bebholi : Ukukhulula i-tappet yevalve ukugcina i-nati kunye nobuso obungalinganiyo bebholithi kunokubangela uxinzelelo olungaqhelekanga kwivalve kwaye ekugqibeleni kukhokelela ekuqhekekeni.
Iicatheter zevalvu : Ukuqokelelana kwekhabhoni egqithisileyo kwiikhathetha zevalvu kunokuthintela intshukumo yevalvu, okukhokelela kuxinzelelo olongezelelweyo kwaye ekugqibeleni kubangele ukuqhekeka kwevalve.
Ezi zinto zingakhokelela ekuqhekekeni kwevalve ye-injini, ngoko ke, kuyimfuneko ukuthatha amanyathelo okulungisa afanelekileyo ngexesha, kubandakanywa ukulungiswa kwevalve, ukutshintshwa kweendawo ezigugileyo, ukucoca iidiphozithi zekhabhoni, njl., Ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini.
