Kuthetha ukuthini ukuqhekeka komoya?
Ukuqhekeka komoya kubhekisa kwimeko apho ivalvu yenjini iqhekekile okanye yaphukile. Le meko idla ngokubangelwa zizinto ezahlukeneyo, kubandakanya isiphelo sentonga yevalvu, ukuguguleka kwe-adjustment screw okanye i-rocker arm okanye ukulungiswa okungafanelekanga, okubangela ukuba i-valve clearance igqithe kakhulu, nto leyo ebangela ukuba isiphelo se-valve tappet singqubane ne-adjustment screw okanye intloko ye-valve rocker arm ingqubane nesiphelo se-valve, nto leyo enokubangela ukuba ivalve iqhekeke. Ukongeza, ukuguguleka okugqithisileyo kwe-CAM, i-valve spring seat off, i-valve tappet fixing nut loose okanye i-adjustment bolt end face evenly, i-valve duct carbon accumulation kunye nezinye izinto nazo zinokukhokelela ekuqhekekeni kwevalvu. Ukuze kuthintelwe ezi ngxaki, kuyimfuneko ukujonga nokugcina injini rhoqo ukuqinisekisa ukusebenza okuqhelekileyo kwezinto ezahlukeneyo .
Ingaba yiblade yokutshixa umoya?
Ipleyiti yokutshixa ucango lomoya yinxalenye, indima yayo kukwenza unxibelelwano oluya kwicala elinye phakathi kwevalvu kunye nesihlalo sentwasahlobo kwaye uyitshixe ukuqinisekisa ukuba ivalvu isebenza ngokuqhelekileyo. Nangona kunjalo, xa ipleyiti yokutshixa ivalvu ingaphumeleli, iya kuba nefuthe elikhulu kwinjini. Umzekelo, ipleyiti yokutshixa inokubangela ukuba ivalvu ivale kancinci, nto leyo ebangela ukuba umlinganiselo wokucinezelwa unganelanga, ize emva koko ibangele ukuba injini ilahlekelwe sisilinda. Kwiimeko ezinzima, ukulahleka kwepleyiti yokutshixa kunokubangela ukuba ipiston ibethelwe kwivalvu, ize ikrazule injini.
Kukho iindlela ezimbini zokudibanisa isiqu sevalvu nentwasahlobo. Enye luhlobo lwe-lock clip, oluxhotyiswe ngee-semi-circular lock clips ezimbini ezikwi-groove yesiphelo se-valve rod, kwaye i-spring seat idibanisa i-lock clip ukuze i-tight hoop ibe sekupheleni kwe-valve rod, ukuze i-spring seat, i-lock clip kunye ne-valve zidityaniswe zibe yinto enye, kwaye i-valve ihambe kunye. Enye indlela kukusebenzisa i-lock pin endaweni yomngxuma we-radial we-lock clamp pin, kwaye uqhagamshele nge-lock pin.
Ziziphi izizathu eziphambili zokuqhekeka kweevalvu?
Eyona nto ibangela ukuqhekeka kweevalvu ziquka ukuguguleka okanye ukulungiswa okungafanelekanga, ukuguguleka kweCAM, isihlalo sentwasahlobo yevalvu esivaliweyo, ubuso obungalinganiyo benati okanye isiphelo sebolt, ukuqokelelwa kwekhabhoni yevalvu.
Ukuguguleka okanye ukulungiswa okungafanelekanga: Ukuguguleka okanye ukulungiswa okungafanelekanga kwesiphelo sentonga yevalvu, isikrufu sokulungisa, okanye ingalo yerocker kunokubangela ukuba ivalvu ivuleke kakhulu, nto leyo enokubangela ukuba isiphelo sevalvu esifakwe ecaleni singqubane nesikrufu sokulungisa, okanye intloko yengalo yerocker yevalvu ephezu kwayo ingqubane nesiphelo sevalvu, nto leyo ebangela ukuba ivalvu iqhekeke.
Ukuguguleka kwe-CAM: ukuguguleka okugqithisileyo kwe-CAM kunokubangela ukuba i-tappet iqhume ngexesha lokusebenza, nto leyo eya kwandisa uxinzelelo lwentonga yevalvu kwaye inokubangela ukuba ivalvu iqhekeke ekuhambeni kwexesha.
Isihlalo sentwasahlobo sevalvu sivaliwe: Ukuwa kwesihlalo sentwasahlobo sevalvu kunokubangela ukuba ivalvu ichaphazeleke ngendlela engaqhelekanga ngexesha lenkqubo yokuvala, nto leyo ebangela ukuqhekeka.
Ubuso be-nut ekhululekileyo okanye ubuso be-bolt obungalinganiyo: Ukukhululeka kwe-nati yokugcina i-valve tappet kunye nobuso be-bolt yokulungelelanisa obungalinganiyo kunokubangela uxinzelelo olungaqhelekanga kwi-valve kwaye ekugqibeleni kukhokelele ekuqhekekeni.
Ii-catheter zevalvu: Ukuqokelelwa kwekhabhoni egqithisileyo kwii-catheter zevalvu kunokuthintela intshukumo yevalvu, okubangela uxinzelelo olongezelelekileyo kwaye ekugqibeleni kubangele ukuba ivalvu iqhekeke.
Ezi zinto zinokubangela ukuba iivalvu zenjini ziqhekeke, ngoko ke, kuyimfuneko ukuthatha amanyathelo okulungisa afanelekileyo ngexesha, kuquka ukulungisa indlela ezisuswe ngayo iivalvu, ukutshintsha iindawo ezigugileyo, ukucoca iidipozithi zekhabhoni, njl.njl., ukuqinisekisa ukusebenza okuqhelekileyo kwenjini.
