Amafutha ugobhozela kwesembozo valve. Avuzayo uwoyela - yini okumele uyenze

Engine Lubrication simiso amandla omlilo yangaphakathi efana ohlelweni womuntu kwegazi. Amafutha, njengoba igazi ukhiphela evaliwe iluphu, indawo yezihlanganisi, Ukupholisa ukuhlanzwa izingxenye ezinyakazayo. Konke lokhu, ngokwemvelo, senzeka ngaphansi ezithile ingcindezi, ukuncishiswa noma idlula zazo njalo kungaholela ukuphazamiseka ukuhamba komsebenzi.

I ukuvuza kancane lwamafutha injini - isibonakaliso yokuthi kwakukhona uhlelo depressurization. Futhi lena isizathu okungathi sína kokucabanga ngakho enifeza ukuhlola samandla iyunithi.

Kulesi sihloko sizoxoxa ngezizathu zokuthi kungani kukhona, futhi kanjani ulungise ukuvuza lwamafutha ngaphansi bonnet.

Kuyini ikhava valve

Lokhu elementi yangaphakathi omlilo injini yakhelwe ukuvikela lo camshaft kusukela yokushayiswa ukungcola, uthuli futhi umswakama. Ngaphezu kwalokho, ikhava ivikela zonke isikhala hood i uwoyela okuyinto sidla icindezelwa ukuba gcoba isikhathi.

Eyokuqala yangaphakathi omlilo izinjini akazange abe ikhava valve, yingakho isikhathi indlela njalo kwakufanele ageze izandla futhi ihlanzekile. Ekugcineni isikhathi steel ikhava wanyathela kusukela mncane zamabhodlela ishidi steel. Namuhla, lesi sici senziwa aluminiyamu ngu ekubumbeni. Futhi akusiwona nje isivalo, kodwa wonke umklamo, okuyinto has umsebenzi kanye isikhathi ukuvikelwa, nokuhlanganyela crankcase ukupholisa uwoyela iqoqo, fafaza izingxenye ezinyakazayo isikhathi indlela.

Ukuze uqinisekise yobunzima kwesembozo valve ekhanda isilinda ngokusebenzisa zenjoloba noma abicah gasket. Ezinye izimoto ezintsha ungafaki pad nhlobo: indima yayo wenziwa ungqimba olukhethekile sealant.

ukuvuza ezingenzeka

Uma uqaphela ukuthi uwoyela ugobhozela kwesembozo valve, zama ukuba ukhombe lapho athatha ukuvuza. Ngokuvamile, igrisi kungaba flow:

• emalungeni we isembozo ikhanda isilinda ngenxa ukugqoka pads noma ingcindezi ngokweqile ohlelweni;
• ezindaweni bolting ikhava nge isilinda ikhanda;
• we yamathebhu uwoyela.

Ezimweni ezingavamile, uwoyela ukuvuza kungavela isembozo izindlu. Lokhu kungase kube ngenxa mechanical umonakalo noma ifektri ukukhubazeka ngesikhathi ukusakaza.

Izizathu uwoyela ukuvuza kusuka Ngibambeni valve

Amafutha ukuvuza kusuka ikhava umphini kungenzeka kubangelwa izici ezimbili:

• ukulahlekelwa uphawu germetizatsionnyh izakhiwo zabo;
• ukwandisa emafutheni ingcindezi ohlelweni.

Esimweni sokuqala gasket esenziwa isikhathi eside wokusebenza nethonya ukushisa noma umane coarsens imifantu ezingase asithinti yobunzima kohlelo. Lokhu akulona icala embi kakhulu. Enough ukushintsha gasket ubudala ngentsha futhi yobunzima kubuyiselwa.

Kodwa uma ukuvuza lwamafutha ikhava valve kubangelwa ukwanda ingcindezi ohlelweni zidinga uphethwe olwengeziwe. Futhi kufanele ziqalise nesilinganiso ingcindezi.

Indlela ukukala ingcindezi amafutha

Njengoba sekuphawuliwe, igrisi ukhiphela ngemigudu ekhethekile motor ngaphansi kwengcindezi eyenziwe futha uwoyela. Ingcindezi evamile namafutha injini ngamunye uhlukile, incike umthamo yayo, inani amasilinda, ama-valve, njll Hhayi ukuqagela, ukubheka Imanuwali ukusebenza imoto yakho, lapho konke kuboniswe. Ngakho, uma ngizwa ingcindezi ohlelweni kuyehla, ke iyoba inzwa kweso leli isibani ezishukiwe ku iphaneli sensimbi. Uma Nokho, okwandisa yayo, akashongo nganoma iyiphi indlela. Ngamanye amazwi, umfutho ophakeme kungaba azimisele kuphela yokuxhuma injini esikhundleni esikhethekile ketshezi manometer inzwa. Ukugxila ubufakazi bakhe, singaphetha ngokuthi amafutha ugobhozela kwesembozo valve ngenxa yokucindezela okwandisa ohlelweni, noma imbangela namanje e gasket (seal).

Yini umfutho ophakeme ngamafutha

Ukuze imoto, kanye nabantu, "ukunyuka komfutho wegazi" akusho azimhambeli kahle. Esimweni sethu, labo-ke iyinkomba yokuthi izinkinga ohlelweni Lubrication. Ngakho, uma yakho uwoyela emotweni luyaphi aphume isembozo valve, futhi uxilongwe nge yokwanda kokungabi ingcindezi, isizathu salokhu kungaba:

• ukungasebenzi ngenxa odla we crankcase ukupholisa uwoyela isihlukanisi grid;
• odla uwoyela isilinda iziteshi ikhanda;
• odla ka lemifanekiso uwoyela;
• wenza umcimbi ingcindezi ukwehlisa valve kule sikhundla avaliwe.

Cabangela lezi zici ngokuningiliziwe, futhi ngokulandelana ukuhlola kangcono, kusukela iningi ezilula eyinkimbinkimbi.

Ukungasebenzi crankcase ukupholisa

Ake uqale nge izizathu ezijwayeleke kakhulu senyusa izinga lomfutho womoya ohlelweni Lubrication, okwenzeka izimoto yasekhaya. Ngokuvamile, amafutha Ngibambeni umphini Vaz iqala owehlela ngenxa yokwephulwa ukupholisa crankcase. Uma sikubeka kalula, igalelo-by amagesi okufanele kube khulula oyophuma injini, ukuhlangabezana nezingqinamba endleleni yayo, futhi baqala ukwakha ngaphakathi, ukudala i overpressure. Kulokhu, it nje kuphela odlulela lwamafutha ikhava valve, kodwa kungase futhi uyiphonse ngokusebenzisa Breather emoyeni isihlungi izindlu.

Yini kungaba ngenxa izithiyo? Okokuqala, kugridi isihlukanisi uma ivimbekile imikhiqizo amandla omlilo. Futhi okwesibili, imali abavamile futhi enenhlabathi phezu kwezindonga engaphakathi Imibhobho esemzimbeni, okuyinto wajoyina ukupholisa hoses. Ngakho uma ushayela lwamafutha Ngibambeni umphini emotweni yethu, hhayi lazy kakhulu ukukhipha ikhava valve futhi uhlanze igridi isihlukanisi, futhi kanyekanye uhlanze Imibhobho esemzimbeni.

amavesi uwoyela ovalekile nokuhlunga

Inhloko isilinda has a yonke inethiwekhi ekhethekile iziteshi lapho uhamba uwoyela. Ukusetshenziswa ongaphakeme-grade amafutha, nokungcola kusuka ngokufaka uhlelo, motor okweqile - lawa sezizathu esiyinhloko lezi ziteshi kungenzeka ukuthi ivimbekile. Uma lokhu kwenzeka, ingcindezi amafutha ngokwemvelo kwandisa, ngoba futha uwoyela uyaqhubeka ukugijima.

Kwenzeka okufanayo uma kusetshenziswa isisefo ivimbekile. It ilahlekelwa amandla ayo, ukudala ingcindezi ngo ohlelweni. Futhi akukho lutho isimanga yokuthi amafutha ugobhozela kwesembozo valve, uma ushintsha lemifanekiso eminyakeni embalwa edlule.

Le nkinga siqedwa ngokufaka esikhundleni isici lemifanekiso siwasebenzise uhlelo usebenzisa uketshezi ekhethekile.

Ukungasebenzi ingcindezi ukwehlisa valve

Ngokuvamile, ukwanda uwoyela ingcindezi is phetho iphutha ingcindezi ukwehlisa valve kwe-futha uwoyela, ngoba yakhe alawule. Imbangela ezivame kakhulu ukwehluleka - wenza umcimbi kule sikhundla avaliwe, kubangelwa ikhishwe mshini imikhiqizo ngomshikisho (swarf) noma ukungcola. Lahla le nkinga ilula. Valve kungenziwa zezikhali kalula futhi bahlanza, kodwa ngeke ahlukanisa futha uwoyela ukwenza lokhu.

Ukukhetha ikhava valve gasket

Nakani ngokwanele ukuba ukukhethwa gaskets, njengoba ukuqeda ukugeleza lwamafutha Ngibambeni valve ngokusebenzisa umkhiqizo yekhwalithi ephansi, wena cishe ukuphumelela. Oluthandwayo kungcono ukunikeza ezingxenyeni zokuqala, siqaphela inombolo zalo zasembonini ikhathalogi. Uma isakhiwo kuyinto gasket iraba, ukuqinisekisa ukuthi ukuthi iraba yayithambile futhi ngingenaso ngokuhlaziya noma nokuwohloka. Zonke lezi ukukhubazeka zimane kuthinte yobunzima.

Kungakhathaliseki kubalulekile gcoba sealant iraba gasket

Kuthiwani ukusetshenziswa sealant auto Mechanics imicabango yabantu washintsha. Abanye bathi ilapho lapho isicelo yayo inadmissible, kuyilapho abanye, kunalokho, zithi kuphela kungenzeka ukuba sifinyelele kophawu ephelele. Ake sithi, uma ebusweni ikhava uMbhalo abe maholoholo ebusweni, isicelo sealant okunxanelekayo, kodwa kuphela uma sisetshenziswa Lihle ungqimba elincanyana. Uma ebusweni siqondile kahle, ungenza ngaphandle kwalo, ngoba eminyakeni embalwa edlule, muntu lokhu kubekwa uphawu is hhayi asijabulele kakhulu. Kodwa imoto, lapho ukufakwa alinikezi design, ngaphandle sealant ongakwazi ukuzenza.

Uma amafutha ogeleza usuka umlomo noma ezindaweni uxhumano aboshelwe

Kwenzeka ukuthi uwoyela akusho ukuthi kuqhamuke njalo kwalapho kuhlangana khona evele kokuzalela ka isilinda ikhanda kanye nekhava valve, futhi, ngokwesibonelo, kusukela yamathebhu uwoyela noma lapho kukhona uxhumano aboshelwe. Imbangela yale ukuvuza kuyinto zonke overpressure efanayo. Ngokuqeda izimbangela nomfutho wegazi ophezulu, kutuswa ukuba esikhundleni gasket iraba ka imishudo (uma ikhona isakhiwo), futhi ukuze uhlole uwoyela ukuvuza yamathebhu cap.

Amacebo eziwusizo

Ekugcineni sikunikeza amanye amathiphu angakusiza ukuba ugweme izinkinga ne avuzayo uwoyela noma ngokushesha ukubhekana nazo.
