Okwesibili, umsebenzi wokulungisa i-valve grease
Ukugcinwa kochwepheshe kwama-valve ngaphambi nangemva kokukhiqizwa kokushisela kudlala indima ebalulekile ekukhiqizeni nasekusebenzeni kwama-valve. Ukugcinwa okulungile nokuhlelekile futhi okuphumelelayo kuzovikela ama-valve, kuwenze asebenze ngokujwayelekile futhi andise impilo yesevisi yama-valve. Ukugcinwa kwe-valve kubonakala kulula, kodwa akunjalo. Kuvame ukushaywa indiva izici zomsebenzi.
***, i-valve grease, ngokuvamile indiva inani lamafutha.
Ngemuva komjovo wamafutha kanye nokufaka i-refueling, opharetha ukhetha imodi yokuxhuma umjovo we-valve ukuze enze umsebenzi womjovo wamafutha. Kunezimo ezimbili: ngakolunye uhlangothi, umjovo wamafutha amancane awanele, futhi indawo yokuvala isheshiswa ukuntuleka kokuthambisa. Ngakolunye uhlangothi, umjovo wamafutha ngokweqile, okuholela ekumosheni. Akukho ukubala okunembile kwamakhono ahlukene okuvala ama-valve okusekelwe ohlotsheni lwe-valve nesigaba. Umthamo wokuvala ungabalwa ngosayizi we-valve kanye nohlobo, bese kuba umjovo ozwakalayo wamafutha afanele.
Okwesibili, amafutha e-valve, ngokuvamile awanaki inkinga yokucindezela.
Ngesikhathi sokusebenza komjovo wamafutha, ukucindezelwa komjovo wamafutha kwabonisa ukuphakama okujwayelekile kanye noshintsho lwesigodi. Ingcindezi iphansi kakhulu, ukuvuza kokuvala noma ingcindezi yokwehluleka iphezulu kakhulu, umlomo womjovo wamafutha uvalekile, amafutha ekutywineni aqinisiwe, noma indandatho yokuvala ivalwe ngebhola le-valve nepuleti levalvu. Imvamisa uma umfutho womjovo wamafutha uphansi kakhulu, igrisi ejovwe igelezela ngaphansi kwegumbi le-valve, elivame ukwenzeka kumavalvu esango amancane. Uma umfutho womjovo wamafutha uphezulu kakhulu, ngakolunye uhlangothi, hlola umlomo womjovo wamafutha bese uwubuyisela esikhundleni uma ukuvaleka kwembobo yamafutha kukhonjwa; Ngakolunye uhlangothi, ukuqiniswa kwamafutha, ukusebenzisa uketshezi lokuhlanza, kuthambisa ngokuphindaphindiwe ukwehluleka kwegrisi yokuvala, kanye nomjovo wokushintshwa kwamafutha amasha. Ngaphezu kwalokho, uhlobo lokuvala kanye nezinto zokubeka uphawu nazo zithinta ingcindezi yomjovo wamafutha, amafomu ahlukene okuvala anomfutho ohlukile womjovo wamafutha, ngokuvamile, ingcindezi yomjovo we-grease seal eqinile iphakeme kunophawu oluthambile.
