Isitywina se-oyile yevalvu yenye yeendawo ezibalulekileyo zeqela levalvu ye-injini, edibana nepetroli kunye ne-oyile ye-injini kumaqondo obushushu aphezulu.
Ngoko ke, kuyimfuneko ukusebenzisa izinto ezinokushisa okuphezulu kunye nokuchasana kweoli, ngokuqhelekileyo zenziwe nge-fluororubber.
Izitywina zesikhondo sevalvu zibonelela ngomlinganiselo ochaziweyo wokulinganisa i-oyile kwisikhondo sesikhondo sevalvu ujongano lweenjini zokutsha zangaphakathi ukuthambisa isikhokelo sevalvu kunye nokunciphisa ukukhutshwa kwe-injini.
Ziyafumaneka kwiinjini zedizili kunye nepetroli kunye nangaphandle kokunyusa.
Ukongeza kwizitywina eziqhelekileyo ze-valve stem, unikezelo lwethu lukwabandakanya izitywina ze-valve ze-injini ezinoxinzelelo oluphezulu kwii-manifolds,
ngenxa yeetshaja zeturbo okanye iziqhoboshi zokuphuma kwiinjini zorhwebo.Ibonisa uyilo olusezantsi lokukhuhlana,
la matywina aphucula umgangatho wezinto ezikhutshwayo kunye nokuphucula ukusebenza kwe-injini ngokumelana noxinzelelo oluphezulu kwi-exhausti kunye namazibuko okungenisa enjini.
Nokuba luhlobo luni lwe-injini, sinikezela ngoyilo oluqhelekileyo lwevalvu yesikhondo sevalvu:
Isitywina esingadityanisiweyo: sizalisekisa umsebenzi wokulinganisa ioli
Isitywina esidityanisiweyo: ukongeza kubandakanya isihlalo sasentwasahlobo ukuthintela ukunxiba kwintloko yesilinda
I-valve stem itywina i-FKM NBR EMNYAMA LULUHLAZA
Ukufakwa kunye nokutshintshwa kwe-valve oil seal
(1) Amanyathelo okuqhaqha isitywina se-oyile yevalvu:
① Susa icamshaft kunye neetapethi zehydraulic, kwaye uzigcine zijonge phantsi.
Qaphela ukuba ungatshintshi iitephu ngexesha lokusebenza.Sebenzisa i-spark plug wrench 3122B ukususa i-spark plug,
lungisa ipiston yesilinda esihambelanayo kwiziko eliphezulu lokufa, kwaye ujike umbhobho we-VW653/3 we-spark plug threaded hose.
② Faka isixhobo sokucinezela entwasahlobo 3362 kwintloko yesilinda ngeebholiti, njengoko kubonisiwe kuMfanekiso.
1. Lungisa iivalve ezifanelekileyo kwindawo echanekileyo, uze udibanise i-hose yoxinzelelo kwi-compressor yomoya (kunye noxinzelelo lomoya ubuncinane be-600kPa).
Sebenzisa i-threaded core rod kunye ne-thrust piece ukucinezela i-valve ezantsi kwaye ususe intwasahlobo.
③ Ibloko yokutshixa ivalve inokususwa ngokucofa kancinci kwisitulo sasentwasahlobo sevalve.Sebenzisa isixhobo esingu-3364 ukutsala ivalve stem oil seal, njengoko kubonisiwe kuMfanekiso 2.
(2) Ufakelo lwevalve stem oil seal.
Fakela umkhono weplastiki (A kumfanekiso wesi-3) kwisiqu sevalvu ukunqanda umonakalo kwivalve entsha yesitywina yeoli.Faka kancinci umaleko we-oyile ye-oyile kumlebe wokutywina we-oyile.
Faka isitywina se-oyile (B kumfanekiso 3) kwisixhobo esingu-3365 uze usityhale kancinane kwisikhokelo sevalvu.Isikhumbuzo esikhethekileyo:
Ngaphambi kokufaka i-valve yokungena kunye nokukhupha, i-oyile ye-injini kufuneka ifakwe kwi-valve stem.
