Iyini imiphumela uma umbhede wesilinda wemoto wonakele?
Ukulimala kombhede wesilinda (ngokuvamile okubhekisele ku-gasket yesilinda) kungonakalisa kakhulu ukusebenza kokuvala ngaphakathi kwenjini, kubangele uchungechunge lwezimpikiswano zamaketanga ezithinta ngqo ukusebenza kwamandla emoto, uhlelo lokupholisa, kanye nohlelo lokugcoba. Uma kungaxazululwa ngokushesha, kungaholela ekulimaleni okukhulu enjinini.
Imiphumela eyinhloko ihlanganisa:
Ukwehla kwamandla enjini kanye nokusebenza okungazinzile: Uma i-gasket yesilinda yonakele, kubangela ukuthi amagesi anomfutho ophezulu ekamelweni lokushisa avuza, okuholela ekucindezelweni okunganele kwesilinda kanye nesilinganiso sokucindezela esincishisiwe. Lokhu kuholela ngqo ekwehleni kwamandla enjini, ubunzima ekusheshiseni, kanye nobunzima ekusheshiseni. Ezimweni ezimbi kakhulu, amasilinda ngamanye angase angasebenzi, okubangela ukudlidliza kwenjini, ukusebenza okungazinzile, noma imisindo engavamile njengokuthi "ukujikijela" noma "ukuqhuma" kanye "nokubhodla".
Uhlelo lokupholisa olungajwayelekile kanye nokushisa kwamanzi okuphezulu kakhulu: Amagesi anomfutho ophezulu angangena emgudwini wamanzi okupholisa, okubangela ukwanda kwengcindezi okungavamile ohlelweni lokupholisa. Lokhu kubonakala njengamabhamuza aqhubekayo avela echwebeni lokugcwalisa ithangi lamanzi, ukusheshisa okungavamile kokusetshenziswa kokupholisa, ukwanda okusheshayo kwesilinganiso sokushisa kwamanzi, ngisho nokubila. Lapho isembozo sethangi lamanzi sivulwa ekuqaleni kokuqala, umuntu angabona inani elikhulu lamabhamuza noma umoya oshisayo uphuma ebusweni bamanzi, futhi ipayipi lokukhipha umoya lingakhipha inkungu yamanzi amhlophe (umhwamuko wamanzi okhiqizwa ukusha kwe-coolant).
Ukungcola kwengxube kawoyela wenjini kanye nengxube ye-coolant: Uma i-gasket yesilinda yonakele, i-coolant ingangena endaweni kawoyela noma uwoyela ungangena ohlelweni lokupholisa. Lokhu kubangela ukuthi uwoyela wenjini uxubane futhi ubole, uveze into "efana nokhilimu" noma "efana ne-paste", okunciphisa kakhulu ukusebenza kokugcoba; ngesikhathi esifanayo, i-coolant ingaxutshwa namafutha, yakhe ama-oyela noma amafilimu kawoyela. Lokhu akugcini nje ngokwenza kube kubi kakhulu ukuguguleka kwezingxenye zangaphakathi zenjini kodwa futhi kungabangela amaphutha amakhulu njengokuthi "isilinda sokudonsa" noma "ukubanjwa kokuthwala".
Ukuvuza kwamafutha kanye ne-coolant: Ekuhlanganeni kwekhanda lesilinda kanye ne-cylinder block, kungase kube khona ukuvuza kwamafutha noma kwe-coolant. Ngesikhathi esifanayo, amagesi anomfutho ophezulu angavuza esikhaleni se-gasket yesilinda noma imigodi ye-bolt yekhanda lesilinda, akhiphe imisindo "yokubhoboza" noma "yokuchofoza". Ukusebenzisa amanzi ensipho kule ndawo kwembula amabhamuza asobala.
Ubunzima bokuqala kanye nokukhipha umoya okungavamile: Ngenxa yokucindezela kwenjini okunganele kanye nokusha okungaphelele kwengxube, injini ingaba nobunzima bokuqala, ikakhulukazi ezimweni ezibandayo. Ipayipi lokukhipha umoya lingaqhubeka nokukhipha umusi omhlophe (ovela ekushisweni kwe-coolant) noma umusi omnyama (ovela engxubeni eningi).
Imiphumela yesikhathi eside: Uma kwenzeka ukuqhubeka nokushayela, i-coolant engena epanini likawoyela izobangela ukuthi ukugcotshwa kukawoyela wenjini kungasebenzi, kusheshise ukuguguleka kwezingxenye ezibalulekile njenge-crankshaft, induku yokuxhuma, kanye nodonga lwesilinda; amazinga okushisa aphezulu kanye nokucindezela okungajwayelekile kungadala ukuguquka kwekhanda lesilinda noma ibhulokhi yesilinda, ukuguguleka kwevalvu, futhi kubangele ngisho "ukudonsa isilinda" noma "ukumiswa" kanye nezinye izinkinga ezibhubhisayo, ngezindleko zokulungisa eziphezulu kakhulu.
Ekuphetheni, umonakalo embhedeni wesilinda awuyona neze inkinga encane. Uma izimpawu ezifana nokushisa kwamanzi okungajwayelekile, ukwehla kwamandla, ukwehla okusheshayo kwe-coolant, kanye nokuhlanganiswa kukawoyela wenjini, imoto kufanele imiswe ngokushesha futhi ihlolwe ngochwepheshe futhi ishintshwe ukuze kuvinjelwe iphutha ukuthi lingaqhubeki.
Umbhede wesilinda, owaziwa nangokuthi i-gasket yesilinda, uyingxenye ebalulekile yokuvala efakwe phakathi kwekhanda lesilinda kanye ne-block yesilinda. Umsebenzi wawo oyinhloko ukugcwalisa izikhala ezincane phakathi kwezindawo ezihlangene ze-block yesilinda kanye nekhanda lesilinda, ukuqinisekisa ukuvalwa kwezindawo ezibalulekile ngaphakathi kwenjini. Isinxephezelo sokungalingani: Umbhede wesilinda uvame ukwenziwa ngensimbi, i-asbestos noma izinto ezihlanganisiwe futhi unokunwebeka okuthile. Ungavala ukungalingani okuncane okungenzeka endaweni ehlangene phakathi kwekhanda lesilinda kanye ne-block yesilinda ngesikhathi sokucubungula nokusetshenziswa, ukuqinisekisa ukuthembeka kwesivalo.
Imelana nezimo ezibucayi kakhulu: Idinga ukusebenza isikhathi eside ezimweni ezinzima njengokushisa okuphezulu, umfutho ophezulu kanye nokugqwala okunamandla. Ngakho-ke, kumele ibe namandla anele, ukumelana nokushisa, ukumelana nokugqwala kanye nokumelana nomfutho ukuqinisekisa ukusebenza okuzinzile kanye nokuphila kwesikhathi senkonzo yenjini.
Ekuphetheni, nakuba umbhede wesilinda umane nje "uyi-gasket", uyingxenye yokuvala eyinhloko eqinisekisa ukusebenza okuvamile kwenjini futhi igcina amandla nokusebenza kahle. Uma sewonakele (okubizwa ngokuthi "ukwehluleka kombhede wesilinda"), kumele ushintshwe ngesikhathi; ngaphandle kwalokho, kuzodala umonakalo omkhulu enjinini.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
