Ama-valve seal - kubiza malini ukuwalungisa? Indlela yokubuyisela lezi zakhi ngaphandle kokukhipha ikhanda? Isinyathelo ngesinyathelo ukushintshwa kwama-valve seal

Kungani kubalulekile ukufaka ama-valve seal agugile? 

Ukungazinaki izimpawu zokuguga kwe-valve seal kungaholela ekulimaleni okukhulu kwenjini kanye nesidingo sokulungiswa kabusha kwenjini. Isevisi ingabiza ama-zloty ayizinkulungwane ezimbalwa, okuvame ukungabi nanzuzo esimweni sezimoto ezisetshenzisiwe. Ngemuva kwalokho okumele ukwenze ukudayisa noma ukuyisa imoto endaweni egunyaziwe yokudilizwa. Ngakho-ke, ukungenelela okusheshayo kuzokuvumela ukuthi unciphise izindleko zokulungiswa nokusetshenziswa okuqhubekayo kwemoto.

Ayini ama-valve stem seal futhi iyini imisebenzi yawo emotweni?

Ama-valve seal, atholakala ekhanda lenjini, ayizici umsebenzi wazo uwukuqinisekisa ukuqina kweyunithi yokushayela. Zivala iziqu ze-valve, zivimbela uwoyela wenjini ukuthi ungangeni kumasilinda. Benza umsebenzi obalulekile, ukuhlinzeka ngophawu phakathi kwamayunithi ahlukahlukene asebenzayo ekhomishini yenjini nokuqinisekisa ukusebenza okulungile kwazo zonke izingxenye. Izigxivizo ze-valve ziyizinto ezingaphansi kokuguga kwemvelo ngenxa yokusetshenziswa nokuguga kwamapulasitiki.

Kuyini ukushintshwa kwama-valve stem seal emotweni?

Ukushintsha ama-valve stem seal emotweni yomgibeli kuyahlukahluka kuye ngemodeli. Kwezinye izimo, amathuluzi akhethekile okuqaqa aklanyelwe uhlobo oluthile lwenjini angasetshenziswa. Bavumela ukulungiswa okusheshayo ngokuhlakaza izakhi zendlela yokulawula i-valve. Ama-seal angabe esesuswa ngokushesha ngokuwasusa emigodini ngethuluzi elifanele. Nokho, ukuxazulula inkinga kuvame ukuxaka kakhulu.

Izinjini eziningi zidinga ukususwa kwekhanda ukuze kufakwe ama-valve seal. Kuyadingeka futhi ukuqaqa yonke indlela ebhekele ukusebenza kwama-valve. Lokhu kuhlanganisa isibopho sokushintsha inani lezinye izici zokuvala, kanye nebhande lesikhathi elisha nokushintsha uwoyela nesipholile. Uma ungenalo ulwazi olufanele kanye nemishini, kufanele unikeze insizakalo endaweni yokusebenzela ethembekile. Inqubo eyenziwe kahle izoqinisekisa ukusebenza kahle kwesikhathi eside kokushayela kwemoto yakho.

Ingabe i-valve stem seal ingashintshwa ngaphandle kokukhipha ikhanda le-cylinder?

Yebo, ungashintsha izimpawu ze-valve stem ngaphandle kokukhipha ikhanda. Kuya ngemodeli yemoto ethile. Kodwa-ke, uzodinga amathuluzi afanele ukwenza lokhu, njengethuluzi elikhethekile namapulangwe okuqinisa ama-valve. Khona-ke kwanele ukuhlakaza indlela yokulawula i-valve injini. Esinyathelweni esilandelayo, usebenzisa okokusebenza ukuze ususe izigxivizo ezindala bese ufaka ezintsha. Yonke le nqubo iyashesha, futhi ukuzenza ngokwakho kungakongela imali eningi.

Ithuluzi namapulangwe okushintsha ama-valve seal 

Ithuluzi elikhethekile lokufaka esikhundleni sezimpawu zamafutha yi-puller evumela ukuthi ususe ngokushesha izimpawu. Lapho unquma ukuthenga lolu hlobo lwethuluzi, naka ukuhambisana kwalo nenjini. Ngokuvamile okokusebenza kwakhelwe amamodeli athile e-actuator, njenge-8V, 12V, 16V, 24V noma 30V. Kumelwe ifakwe ububanzi nobude bengcindezi obulungisekayo. Izixazululo zobungcweti kule ndawo nazo zinesakhiwo esiqinile esenziwe ngeshidi lensimbi elinephrofayili elimbozwe ngongqimba olulwa nokugqwala.

Izikhonkwane ezisezingeni eliphezulu zokushintsha ama-valve seal azokuvumela ukuthi ususe kalula iphutha bese ushintsha i-gasket engalungile. Qinisekisa ukuthi ukhetha imodeli enemihlathi emide eyanele ukukuvumela ukuthi usebenze ngama-valve ezindaweni okunzima ukufinyelela kuzo. Uma ungaqiniseki ukuthi uhlobo oluthile lwedivayisi luyahambisana yini ne-powertrain yemoto yakho, thintana nomthengisi wakho. Kukhona umehluko phakathi kokuklanywa kwezinjini zikaphethiloli nezinjini zikadizili zabakhiqizi ngabanye.

Yiziphi izimpawu zokuvuza nama-valve seal acekeleke phansi adinga ukulungiswa?

Esinye sezibonakaliso zokuqala zokuvuza kanye nokulimala kwama-valve seal ukubonakala kwentuthu eluhlaza okwesibhakabhaka ephuma epayipini lokukhipha umoya. Lesi simo akufanele siphanjaniswe ne-exhaust emhlophe (ngenxa ye-coolant evuthayo) noma i-exhaust emnyama (ngenxa yengxube engafanele ezinjinini zikadizili). Khumbula ukuthi ukwehluleka ukufaka uphawu kahle ngeke kubangele ukwehluleka ngokushesha. Ngenxa yalokho, i-soot iqoqa kancane kancane, i.e. umule namadiphozithi acekela phansi kancane izingxenye ezisegumbini lenjini. Izakhi zokuvala ngokuvamile zidinga ukushintshwa ngemva kwamahora angaba ngu-100. imayela.

Ukusetshenziswa kukawoyela ngokweqile, okutholwa ngesikhathi sokuhlolwa kwezinga likawoyela ngezikhathi ezithile, kufanele nakho kukwenze usolise. Ukushintsha ama-valve stem seal kungase kudingeke futhi esimweni sokukhishwa kwentuthu eluhlaza okwesibhakabhaka okukhulunywe ngayo ngaphambili, okuvame ukwenzeka lapho injini imiswa futhi ishaya kancane noma ingenzi lutho. Iphunga lamafutha ashisiwe endaweni yenjini lingabuye lihlotshaniswe nama-valve stem seal. Kubike kuchwepheshe wokuxilonga ngokushesha ngemva kokuthola inkinga.

Ziyini izindleko zokuthenga nokufaka esikhundleni sezimpawu zamavalvu enjini?

Ukuthenga amaphedi ngokwawo ngeke kubize kakhulu. Izindleko zezimpawu zikawoyela zisukela kokumbalwa kuye kwamakhulu ambalwa e-zł uma kuyizinjini zesimanje ezinamandla kakhulu. Ukushintsha ama-valve stem seal kuyabiza ngenxa yobunkimbinkimbi bokusebenza. Kuphinde kuvame ukubandakanya ukufakwa kwama-gaskets amasha ekhanda kanye nesembozo sevalvu, kanye namabhande esikhathi amasha sha. Kufanele futhi ukhumbule ukugcwalisa injini ngamafutha amasha, kanye nokuthenga into epholile.

Kungenzeka yini ukufaka ama-valve stem seal ngaphandle kokukhipha ikhanda?

Ukushintshwa okujwayelekile, okuzimele kwezimpawu ze-valve stem ngaphandle kokukhipha ikhanda kungenzeka, kodwa kuyadingeka ukuba nemishini efanelekile yokuyifeza. Kudingeka izinsimbi ezikhethekile zokuvala ama-valve namathuluzi akhethekile. Kodwa-ke, akulula ngaso sonke isikhathi ukulungisa ama-valve ama-valve ngaphandle kokuhlakazeka kwe-valve okuyinkimbinkimbi. Khona-ke kufanelekile ukuphathisa inqubo kumakhenikha onolwazi. Khumbula ukuthi amaphutha okuxazulula inkinga angabangela umonakalo ongalungiseki enjinini.

Ukushintshwa okushibhile nokusheshayo kwama-valve stem seal

Uma ngenkathi ushayela ubona noma yiziphi izimpawu ezingase zibonise isidingo sokushintshwa ngokushesha kwezimpawu ze-valve stem, khona-ke kufanele nakanjani uqale ukulungisa ngokushesha noma uye ku-diagnostician oseduze. Ukufunxa intuthu eluhlaza okotshani noma iphunga lamafutha ashisiwe yizimpawu ezivame kakhulu zokuvuza. Izindleko zama-sealants zamamodeli ezimoto ezidume kakhulu azidluli amashumi amaningana ama-zloty. Ukuxazulula izinkinga ngesikhathi kuvimbela ukulungisa okubiza kakhulu.

Ukushintshwa okushibhile nokusheshayo okwenziwe ngokusheshisa kwe-valve stem seal yeyunithi yokushayela kuzosindisa imoto ekulimaleni okubi kakhulu noma ukulahlwa. Ukusebenzisa amathuluzi akhethekile ngendlela yamapulangwe ukususa indlela yokulawula i-valve, ungayenza ngokwakho. Nokho, khumbula ukuthi lokhu kudinga ulwazi olukhethekile, futhi iphutha elincane lingaholela esidingweni sokulungiswa kabusha kwenjini. Ngalesi sizathu, cabanga ukunikeza isevisi kumakhenikha onolwazi.
