Uyini umsebenzi we-gasket yesilinda semoto?
Ohlelweni olunembile lwenjini yemoto, i-gasket yesilinda iyinto elula ukuyinaka kodwa ebaluleke kakhulu.
Kufana nonogada othule, ovikela njalo ukusebenza kwenjini. Uma seyehlulekile, kuzobangela ukusabela kweketanga, okuthinta ukusebenza kwemoto iyonke.
Umsebenzi oyinhloko we-gasket yesilinda ukuvala. Ihlanganiswe ngokuqinile phakathi kwe-cylinder block nekhanda lesilinda, igcwalisa izikhala ezincane kanye nokungalingani kwendawo ehlangene, futhi yakhe isithiyo esiqinile sokuvikela. Okokuqala, kumele iqinisekise ukuvalwa kwegumbi lokushisa. Lapho injini isebenza, isilinda izokhiqiza amazinga okushisa afinyelela ku-degrees Celsius eziyizinkulungwane eziningana kanye nokucindezela kwamashumi ama-megapascal. I-gasket yesilinda ingavimbela ngempumelelo ukuvuza kwegesi, iqinisekise ukuthi ingxube evuthayo ishiswe ngokuphelele futhi iguqule amandla abe amandla ngezinga eliphezulu. Uma ukuvala kwehluleka, ukuvuza kwegesi kuzobangela ukwehla kwengcindezi yesilinda, ukwehla okukhulu kwamandla enjini, kanye nokwenyuka okukhulu kokusetshenziswa kukaphethiloli.
Okwesibili, i-gasket yesilinda inesibopho sokuhlukanisa i-coolant ku-oyela wokugcoba. Uhlelo lokupholisa lwenjini kanye nohlelo lokugcoba lunemisebenzi yalo. I-coolant iyajikeleza ukuze isuse ukushisa, kuyilapho uwoyela wokugcoba uhlinzeka ngokugcoba izingxenye ezihambayo. I-gasket yesilinda, ngesakhiwo esikhethekile sokuvala, ivumela lezi ziphuzo ezimbili ukuthi zigeleze eziteshini zazo ngendlela ehlelekile ngaphandle kokuphazamisana. Uma i-gasket yesilinda yonakele, i-coolant ingangena ku-oyela wokugcoba, okubangela ukuthi uwoyela wokugcoba uxube futhi ulahlekelwe ukusebenza kwawo kokugcoba; uwoyela wokugcoba ungaxubana ne-coolant, okuthinta umphumela wokupholisa, futhi ezimweni ezimbi kakhulu, okubangela amaphutha abulalayo njengokudonsa isilinda, ukuminyana kwe-crankshaft, njll.
Ngaphezu kwalokho, i-gasket yesilinda nayo inemisebenzi yokusiza yokubopha kanye nokulawula izinga lokushisa. Ukudlidliza okukhiqizwa yinjini kuzomuncwa kancane yizinto ezinwebekayo ze-gasket yesilinda, kunciphisa ukushayisana okuqinile phakathi kwe-block yesilinda kanye nekhanda lesilinda futhi kunciphise ukuguguleka kwezingxenye zensimbi. Ngesikhathi esifanayo, kungasiza ekulinganiseni izinga lokushisa lekhanda lesilinda kanye ne-block yesilinda, kugweme ukushisa ngokweqile kwendawo okubangela ukuguqulwa kwensimbi, futhi kugcine injini isendaweni efanele yokusebenza.
Uma i-gasket yesilinda ihluleka, injini izokhipha uchungechunge "lwezibonakaliso zesexwayiso". Ukubonakaliswa okusobala kakhulu ukwehla kwamandla. Uma ushayela, ukusheshisa kwemoto kuhamba kancane, ngisho noma ucindezela i-accelerator kanzima, akukho mizwa yokusunduza emuva, futhi kuzoba nokuzamazama okuvamile lapho ingasebenzi, okufana nokuntuleka kukaphethiloli. Lokhu kungenxa yokuthi ngemva kokuba i-gasket yesilinda yonakele, igesi enomfutho ophezulu ekamelweni lokushisa iyavuza, okubangela ukucindezeleka kwesilinda okunganele kanye nengxube engashiswanga ngokuphelele.
Izinto ezingavamile ohlelweni lokupholisa nazo kudingeka ziqaphe. Isikhombisi segeyiji yokushisa kwamanzi sikhuphuka ngokushesha, noma ithangi lamanzi "liyabila", ukungena kwamanzi okupholisa kwerediyetha kuqhubeka nokukhipha amabhamuza, lokhu kungaba yizibonakaliso zokwehluleka kophawu lokudlula kwamanzi okupholisa lwe-gasket yesilinda. Okuvame kakhulu "ingxube yamanzi kawoyela": izinga lamanzi ethangini lamanzi linefilimu kawoyela elintantayo, noma igobolondo elingezansi likawoyela linamafutha okugcoba anombala wobisi, okubonisa ukuthi i-coolant namafutha okugcoba angene ngaphakathi. Ngalesi sikhathi, kuyadingeka ukulungisa ngokushesha.
Isimo sokukhipha umoya singabonisa nesimo sempilo se-gasket yesilinda. Ngesikhathi sokuqala okubandayo, ipayipi lokukhipha umoya likhipha umusi omhlophe ojiyile onephunga elimnandi kancane, elivame ukubangelwa ukuhwamuka kwe-coolant ekamelweni lokushisa. Uma kukhishwa umusi oluhlaza okwesibhakabhaka, kungenzeka ukuthi uwoyela ungene ekamelweni lokushisa futhi wahlanganyela ekushiseni. Ngaphezu kwalokho, imisindo yokugeleza komoya "okuqhumayo" noma ukungqongqoza kwensimbi nakho kungaba izimpawu zomonakalo we-gasket yesilinda, kanye nokuvuza kwegesi okwandisiwe kanye nokuguguleka okusheshayo kwezingxenye.
Izimbangela zokwehluleka kwe-gasket yesilinda ziyahlukahluka. Ngaphandle kokuguga ngokwako, amazinga okushisa aphezulu enjini angenye yezimbangela eziyinhloko. Amazinga okushisa aphezulu aqhubekayo azokwenza ikhanda lesilinda kanye nebhulokhi yesilinda kukhule futhi kuguquke ngale kwebanga lokubuyisela le-gasket yesilinda, okuholela ekwehlulekeni kokuvala. Ngaphezu kwalokho, i-torque engalingani lapho kuqinisa amabhawodi ekhanda lesilinda, ukusebenza okungafanele, noma ikhwalithi ephansi ye-gasket yesilinda ngokwayo nakho kungandisa ingozi yokwehluleka.
Uma bebhekene nokwehluleka kwe-gasket yesilinda, abanikazi bezimoto akumelwe bakuthathe kalula. Uma sekutholakale ukuphazamiseka okungenhla, kufanele baye ngokushesha esikhungweni sokulungisa sochwepheshe ukuze bahlolwe. Ngesikhathi sokulungiswa, akudingi nje kuphela ukuthi kushintshwe i-gasket yesilinda entsha, kodwa futhi nokuthi ikhanda lesilinda kanye ne-block yesilinda kudinga ukuhlolwa. Uma kukhona ukuguquguquka, kudinga ukulungiswa ukuze kuxazululwe inkinga ngokuphelele futhi kubuyiselwe injini ekusebenzeni okuzinzile.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
