Yomiselela umphini stem lwezimpawu ngaphandle kokukhipha ikhanda. Kungakanani kukhona lwezimpawu valve stem?

izinjini Modern ubuchwepheshe ethuthukile, futhi izinkampani zathuthuka kahle kakhulu e ukuthuthukiswa Nokho, namanje ekwakhiweni kwamandla Amayunithi izingxenye kanye izingxenye, okuyizinto namanje ngenkuthalo azigugi zidinga esikhundleni njalo ngezikhathi ezithile. Valve stem lwezimpawu (noma, njengoba zibizwa kanjalo kungenjalo, eliqinisa valve) - ingenye okudlekayo for imoto. Nokho, ukufaka izingxenye ezintsha kufanele bazikhandle, ngoba usethe endaweni akude kakhulu motor. Njengoba ezothatha isikhundla umphini stem lwezimpawu ngaphandle kokukhipha ikhanda ngeke lula ukuphila abashayeli.

imisebenzi

Valve - ingxenye kunalokho ebalulekile isikhathi. Ingxenye engenhla imininingwane endaweni lapho njalo engabiza uwoyela inkungu. Ingxenye engezansi valve itholakala endaweni lapho njalo kuwufanele slurry aminyene amathonsi amancane uphethiloli. Uma esitolo esidayisa valve, kuba imvelo kunalokho nolaka kushisa kakhulu amandla omlilo amagesi.

Ukuze operation evamile isikhathi udinga ukuya kwafika igrisi. Nokho, kuyinto efiselekayo ukuthi uwoyela ingena uMbhalo. Ngakho, lapho valve iminyakazo igrisi isuswe okuthiwa isiketi zokuzivikela. Lena valve stem uphawu.

abakhiqizi Car ukuncoma ukulungisa lezi zimpahla lapho ikhanda isilinda iyasuswa. Kodwa esikhundleni umphini stem lwezimpawu ngaphandle kokukhipha ikhanda ezimbi zingenza nokuhlukileko.

Izimiso Operation induku nokupakisha

Lapho ketshezi lubricating ingena uMbhalo stem valve, khona-ke kuyinto kwakwakhe uwoyela nenye emoyeni nophethiloli. Ngemva ukuthungela ingxube uphethiloli nowoyela zishiswe. Ngenxa yalokho, phezulu disc valve futhi esihlalweni valve kwakhiwa umule.

Lokhu ngokuvamile kuholela Ukuwohloka cell izici - kokuba uyeke ukuvala. Amafutha ne-carbon ezifakwa futhi kwakheka kwi izindonga ekamelweni amandla omlilo, phezu piston futhi indiza emasongweni. Konke lokhu-ke kuholela kahle futhi anda injini bafake.

Kodwa akugcini lapho. Amafutha okuyinto eseke wangena uMbhalo, nekusebenta omlilo siba sibi nophethiloli.

iyona cap kanjani?

Nothayi banamuhla le ndlala kuyinto cap akhiwe ngerabha futhi ngaphakathi lapho emikhonweni eyenziwe ngensimbi futhi olwandisa entwasahlobo. Yena ngokuqinile ngazo izingxenye ichopho stem valve.

Indlela ukucacisa ukusebenza?

Kusebenta kungenziwa kunqunywa design, kodwa nqampuna umhlabeleli kunqunywa impahla kuyiphi into ekhiqizwa. Uma umkhiqizo consumable wenziwe i iraba acrylate noma fluoro ke ukusebenza kuyoba at kokuwa.

Ngezinye izikhathi ungase ukuthole amasongo PTFE lapho kungekho ukuqinisa. Ayizwakali, futhi crimping Kwenziwa sibonga onqenqemeni ububanzi.

Ofeleba ukuthi basuke efakwe kwi Vaz izinjini, futhi izinto ezifanayo, kodwa onobuhle phezulu bonke Brands angaphandle angase abe nokuphila inkonzo efanayo.

Kubalulekile ukwazi kahle hle ukuthi yiziphi Seals ukufakwa motor. Phela, enikela inkonzo ezifana esikhundleni valve stem zamanzi, intengo kungaba eliphezulu kakhulu. Isiteshi inkonzo, ngaphambi kokuthi ukwenza lo msebenzi, ahlukanisa amandla iyunithi cishe ngokuphelele.

Yomiselela kuhilela ukusetshenziswa okudlekayo kuphela yasekuqaleni motors ethize.

Kungani valve seal uzokhathala?

Crankshaft izinjini ungakwazi azungeze lapho ezihambayo ngesivinini esingafinyelela ku-4500 rev / imiz. Ngomzuzu owodwa, ngamunye valve ongenza kuze kufinyelele 1200 nowe. Ngokwemvelo, cap iyasebenza umthamo omkhulu futhi bacindezelekile ezinzima. Ngisho uphawu uwoyela echayeke okuhlaselwa amafutha bese kuthi amagesi esishisayo.

Ngenxa yalokho, indaba kusuka okuyinto wenza nomlilahlo Uqinisa. Izingxenye ukusebenza kancane kancane abraded futhi zigqokwe. Le mininingwane ngezikhathi ukushintshwa, kodwa akufanele sicabange ukuthi ziyashintsha, like ikhandlela.

izitshalo Modern imoto ukukhiqiza imikhiqizo ngokuphila service - kuze kube namakhulu amakhilomitha. Kodwa zikhona izinjini, lapho lolu shintsho kuyodingeka okuningi. Ngokwesibonelo, kuba omunye izimbangela ukwehluleka izimoto Vaz. Ukulungisa kuyehla kube esikhundleni elula.

Izimpawu ukuwohloka kwamangqamuzana indlala induku

Abashayeli abanokuhlangenwe ukushayela emnandi kakhulu, azi izici eziyinhloko esikhundleni eziphuthumayo. Lokhu isinemfu amakhandlela, lo isifiso yanda ngenxa yamafutha, umusi ipayipi qeda.

Yomiselela kungcono ukwenza lapho kuqubuka. Kodwa uma wenza kamuva, wena bayozibuthela idiphozi, futhi injini uzolahlekelwa amandla.

Indlela ukukhetha ofanele esijamiselako?

Kuze kube manje, izinkinga ngokuthengwa kwanoma iyiphi izingxenye abekho. Ukunikezwa zonke izimvu zamanzi valve stem. intengo zabo - ruble 200. Kodwa akufanele ngakususi ukuthi esikhathini esitolo yezimoto ayikwazi ukuthi Kunconywa ngumkhiqizi.

Uma sikhuluma Ukukhetha kunezimvu zamanzi, injini onobuhle okuthuthukile, ungasebenzisa acrylate entsha noma umkhiqizo fluororubber. Kodwa futhi angasetshenziswa izimoto Vaz. Ukulungiswa izobiza kancane ezibizayo, kodwa izinga isesikhathini par.

Kubalulekile futhi ukuba ayicabangele lapho ekhetha imininingwane iphrofayli kwangaphakathi. Ngokwesibonelo, Japanese ukukhiqizwa amayunithi zinama kwangaphakathi cap onqenqemeni. Musa ulinge - imikhiqizo enjalo emikhonweni bushelelezi omane ungeme.

Kungakanani kukhona lwezimpawu valve stem?

Namuhla isendalini zikhona izinto ezahlukene ongazikhetha zonke izimoto. Eqolo kungadla kuze ruble 1000. Ofeleba for izinjini yasekhaya kungadla umnikazi wemoto penny nje.

enze esikhundleni

Utholé emotweni yakhe izimpawu ejwayelekile zokukhandleka ofeleba futhi izoshintsha. Une ngikhethe noma ukufaka isicelo esiteshini inkonzo futhi bachitha imali enhle bahlangane futhi disassembly ikhanda isilinda, noma enze yonke umsebenzi wena.

Futhi uma ku workshop kuyoba ukuqaqa inhloko, ezimele esikhundleni umphini stem lwezimpawu ngaphandle kokukhipha ikhanda - kuba ishibhile futhi kulula. Ngokwemvelo, udinga okungenani okuhlangenwe nakho yokulungisa.

amathuluzi adingekayo

Ukuze lo msebenzi, udinga i-abuthe lamathuluzi. Kuyadingeka isethi indinganiso injini. Ngaphezu kwalokho, uthole impintshisi ne amathuluzi akhethekile cindezela entwasahlobo valve. Ngisho sithathe udlawana - nalo uzothola imvuthu. Ngisho ukulungiselela Ithuluzi fitting lwezimpawu entsha. Ngokwemvelo, ewusizo isando induku tin ububanzi hhayi ngaphansi kuka 8 cm.

Njengoba ezothatha isikhundla umphini stem lwezimpawu ngaphandle kokukhipha ikhanda ngezandla zakhe

Njengoba isibonelo, ukuthatha imoto Vaz. Ake sibone ukuthi ushintsha valve seal 2109.

Okokuqala ukhipha ikhava ekhanda. Ngokulandelayo, ukushintshanisa crankshaft. Ijikise kuze kube yilesi sikhathi, kuze kube uphawu sprocket kushaft ngentambo uphawu esindayo. Ngokulandelayo, ukususa eziveza izindlu kanye camshaft. Manje ungakwazi ukulungisa iketango sprocket. Manje unqamule izintambo kusukela amakhandlela Ihambe amakhandlela.

Okuhle cindezela entwasahlobo bese ususa valve drive isigwedlo. Susa screw ukulungisa, futhi endaweni yawo ithuluzi kokususa isikulufa iziphethu. Umgodi lapho kwakukhona khona ikhandlela okulungiselelwe tin faka induku. Lokhu kwenziwa ukuze uvale valve. It uhlala crackers khulula ngosizo amathuluzi akhethekile.

Manje ungabona lwezimpawu. Ukuze uqonde ukuthi ukushintsha ofeleba valve stem, kuzomele uqale ukuhlola isimo sabo. Kodwa kunconywa ukushintsha konke ngesikhathi esisodwa. Ukuze wenze esikhundleni kudingeka chuck collet. Ngakho, nge imivimbo ukukhanya angasuswa valve stem lwezimpawu. Asikho isidingo ukusebenzisa idrayivu ukuphuma inqubo, isikudilayiva ahlukahlukene noma ezinye ithuluzi okungalungile.

Manje kufanele agqoke into entsha ku-valve. Yenza lokhu ngokucophelela. Ebusweni engaphakathi indlala kungenziwa nivame. Ngakho into ngeke uhambe kulula. Ukuze yokugcina ngokucindezela kalula badonsa emzimbeni.

Njengoba ubona, kulula ukwenza operation ezifana esikhundleni valve stem lwezimpawu. Intengo amasevisi anjalo esikhathini iziteshi kuyinto isibhakabhaka-okusezingeni eliphezulu, ngakho-ke ngeke nje uthole okuhlangenwe nakho e yokulungisa izimoto, kodwa futhi imali yakho.
