Yintoni isigqubuthelo sevalvu ?
Isigqubuthelo sevalve yipleyiti yokugquma esetyenziselwa ukukhusela icamshaft ngaphezulu kwegumbi levalve kwaye yenze umngxuma ovalekileyo onentloko yesilinda (kukwakho neendawo zokubuyiswa kweoyile, iipaseji zokuhambisa ioyile kunye nezinye iipaseji zeoyile ezidityaniswe neminye imingxunya)
Yintoni unobangela wokuvuza komoya kwisigqubuthelo sevalvu?
Ukuvuza komoya kwisivalo sevalvu kuya kubangela ukuba isithuthi singakwazi ukuqhuba.Ukuba umxube ucebile kakhulu okanye uncinci kakhulu, ioli ekwigumbi lokutsha ayitshisi ngokupheleleyo, okubangela ukwanda kokusetyenziswa kwamafutha.Kwakhona kuya kubangela ukuba imoto ihambe ngokukhawuleza.I-injini inzima ukuqalisa, amandla ayancipha, ukutsha akuphelelanga, idiphozithi yekhabhoni inzima, kwaye iisilinda zodwa aziyi kusebenza.Ngokuqhelekileyo, ukuba kukho ukuvuza kweoli, kuyacetyiswa ukuba utshintshe isivalo sevalve
Ngaba ayinamsebenzi into yokuba isivalo sevalve sivuza i-oyile?
I-valve cover gasket ivuza i-oyile, echaphazela isithuthi.Kufuneka itshintshwe ngexesha.Isigqubuthelo se-gasket sisetyenziselwa ukutywina ukuthintela ukuvuza kwe-oyile.Ukuba ayitshintshwanga ngexesha, itywina liya kuncipha, libe lukhuni, lilahlekelwe yi-elasticity kwaye liphuke kakhulu.Ukuba nje kukuvuza kweoli okubangelwa ukuguga kwentloko yevalve cylinder, ingxaki inokusombululeka ngokutshintsha intloko yevalve yesilinda entsha.Ukuba uzithengela ngokwakho, ixabiso limalunga ne-yuan eyi-100.Ukuba uya kwivenkile ye-4S ukuze uyitshintshe, iya kuba yi-200 ye-yuan ubuncinane.I-gasket yesigqubuthelo sevalve ngokuqhelekileyo yenziwe ngerabha, kwaye enye yeempawu eziphambili zerabha kukwaluphala.Ngoko ke, ukuba ubomi benkonzo yesithuthi bude kakhulu, izinto zerabha ziya kuguga kwaye zibe lukhuni, kubangele ukuvuza kweoli.Xa utshintsha, nikela ingqalelo kwezi ngongoma zilandelayo.Xa utshintsha, coca ngokupheleleyo indawo yoqhagamshelwano.Faka iglu ukuba unako, kuba kuthatha ixesha elide ukusebenzisa iglue.Kulungile ukuba ungayifaki iglu.Kuxhomekeke kwiminqweno yomnini.2. I-injini kufuneka ipholiswe ngokupheleleyo phambi kokuba itshintshwe.3. Xa ufaka i-valve cover, qinisa amaxesha amaninzi ngediagonally.Emva kokulungisa isikrufu, buyela kwi-screw diagonal.Oku kuya kuthintela uxinzelelo olungalinganiyo kwigasket yesigqubuthelo sevalve.
Ingaba isigqubuthelo sevalve sikhangeleka sibi njani?
Kukho izizathu ezininzi zomonakalo we-valve cover gasket.Eyokuqala kukuba ibholithi ikhululekile, eyesibini kukuvuthela kwe-injini, eyesithathu kukuqhekeka kwesivalo sevalvu, kwaye eyesine kukuba igaskithi yesivalo sevalvu yonakele okanye ayifakwanga ngesitywina.
Ngexesha lokunyanzeliswa kwe-injini, ixabiso elincinci legesi liya kuhamba ukusuka eludongeni lwe-cylinder kunye neringi yepiston ukuya kwi-crankcase, kwaye uxinzelelo lwe-crankcase luya kunyuka ngokuhamba kwexesha.Ngeli xesha, ivalve ye-crankcase ventilation isetyenziselwa ukukhokelela le ndawo yegesi kwindawo eninzi yokungena kwaye iyifunxe kwigumbi lokutsha ukuze iphinde isetyenziswe.Ukuba ivalve ye-crankcase ventilation ivaliwe, okanye indawo evulekileyo phakathi kweringi yepiston kunye nodonga lwesilinda lukhulu kakhulu, okukhokelela kumoya ogqithisiweyo womoya kunye noxinzelelo oluphezulu lwe-crankcase, irhasi iya kuvuza kwiindawo ezinokutywinwa okubuthathaka, okufana ne-valve cover gasket. , ngaphambili nangasemva i-oyile ye-crankshaft, ekhokelela ekuvuzeni kwe-injini.
Ngethuba nje usebenzisa i-sealant, qinisa iibholithi, kwaye i-valve cover ayiqhekeki okanye ikhubazeke, ibonisa ukuba isivalo sevalve silungile.Ukuba awukhululekanga, ungasebenzisa irula kunye negeyiji yobunzima (igeyiji yokubona) ukulinganisa ukucaba kwesigqubuthelo sevalvu ukubona ukuba asigrumbi na.
