Ungawuhlukanisa kanjani umthombo we-valve? Ukwehluleka okuvamile kwentwasahlobo ye-valve
Okokuqala, amazwi ambalwa mayelana nezimoto. Intwasahlobo yevalvu itholakala phakathi kwekhanda lesilinda kanye nesihlalo sentwasahlobo ekugcineni kwesiqu sevalvu. Umsebenzi wayo ukuqinisekisa ukuthi ivalvu ingafakwa eduze nesihlalo sevalvu noma indandatho yesihlalo sevalvu lapho ivalvu ivaliwe, kanye nokunqoba amandla angenawo amandla akhiqizwa yindlela yevalvu lapho ivalvu ivulwa, ukuze izingxenye zokudlulisela zihlale zilungiswa yi-CAM ngaphandle kokuhlukaniswa. Ngakho-ke ungayisusa kanjani intwasahlobo yevalvu? Kungakanani okwaziyo?
Indlela yokudiliza i-valve spring: ukudiliza.
Isipilingi sevalvu siyithuluzi elincane eliqinisekisa ukuthi ivalvu ihlezi kahle futhi ifakwe kahle, okuvimbela ivalvu ukuthi ingagxumi lapho injini idlidliza futhi yonakalise ukusebenza kwayo kokuvala.
1. Faka isikulufu esiphelele soxhumano olunentambo se-valve spring compressor emzimbeni wesilinda;
2. Cindezela ikhanda lokucindezela le-compressor yentwasahlobo yevalvu esiphethwini sevalvu;
3. Bamba isibambo ngesandla sakho bese ucindezela phansi kuze kube yilapho isibambo sesilingana. Kuleli qophelo, ungafaka isibambo sokukhiya umnyango womoya.
Indlela yokususa iziphethu zamavalvu: Iziphethu zamavalvu zivame ukwehluleka.
1. Ngaphansi kwesenzo sesikhathi eside sokushisa okuphezulu kanye namandla ashintshana ngezikhathi ezithile aphezulu, isiphethu se-valve kulula ukusigqoka nokusishintsha ngemva kwesikhathi esithile. Kulesi simo, ukuqina kwesiphethu kuzoncipha futhi kunciphe, okuthinta ukuvalwa kwe-valve kungabi kuqinile, amandla enjini yomshini ancishisiwe, futhi kunzima ukukusetha lapho uqala. Uma imoto ima endaweni yokuhlangana, ingabe abangani bazocabanga ngesimo sokuhamba ngaleso sikhathi?
2. Indandatho yesipilingi se-valve ithintwa yikhwalithi engeyinhle, ukuthamba okubuthakathaka noma ukuphambuka noma ukuphuka kwesipilingi se-valve. Uma injini ingasebenzi, umsindo "wokuchofoza" ungezwakala kahle ekhava yegumbi le-valve, futhi ngezinye izikhathi kuba nomsindo wokubhonga. Ezimweni ezimbi kakhulu, ukusebenza kwesivinini semoto kuyancishiswa, futhi isimo sobunzima bokuqala kanye nomsebenzi wamasilinda ngamanye awusheleli.
3. Uma ukuqina kwentwasahlobo yevalvu yokuphuma kukawoyela kuncipha. Kuzobangela ukuvuza okukhulu kukawoyela ocindezelekile, kwehle ingcindezi esele epayipini likawoyela ocindezelekile, ivalvu kawoyela ayikwazi ukuhlaliswa ngokushesha, ukuphakelwa kukawoyela kuba kufushane futhi kungazinzile, futhi injini ayikwazi ukusebenza noma "ukuhamba". Ngaphezu kwalokho, kungenza futhi i-injector iqale ukufutha uwoyela obuthakathaka, olula unqamuke, bese kuba khona into yokuwa. Ngemuva kwalokho kuzothinta ukushisa ngokweqile kwenjini, ukuwohloka kokusha, intuthu yokukhipha umoya kanye nokunye ukungcola kwemvelo okudingekayo.
