Iyini uphawu lwamafutha olungaphambili lwe-crankshaft yemoto?
I-oyili yangaphambili ye-crankshaft yemoto iyisici esibalulekile sokuvala injini, esisetshenziswa kakhulu ukuvimbela ukuvuza kwamafutha okugcoba (uwoyela wenjini) kusukela ekugcineni kwe-crankshaft nokuvimba uthuli, amanzi kanye nokungcola ukuthi kungangeni ngaphakathi kwenjini.
Imisebenzi eyinhloko
Ukuvala uwoyela wenjini: Ngesikhathi sokujikeleza kwe-crankshaft ngesivinini esikhulu, kuqinisekisa ukuthi uwoyela wenjini awuphumi esikhaleni esiphakathi kwe-crankshaft kanye nebhokisi lenjini.
Ukuvimbela uthuli nokungcola: Ukuvimbela ukungcola kwangaphandle ukuthi kungangeni ngaphakathi kwenjini, ukuvikela izingxenye ezibalulekile ezifana nama-bearings.
Ukugcina ukuzinza kohlelo lokugcoba: Ukuqinisekisa ukusebenza okuvamile komjikelezo wokugcoba wangaphakathi enjinini nokugwema amaphutha amakhulu njengokubanjwa kwesilinda kanye nokushiswa kwamabhere ngenxa yokuntuleka kwamafutha. Indawo yokufaka
Itholakala engxenyeni engaphambili yenjini, ikakhulukazi phakathi kwe-crankshaft kanye ne-casing yenjini, ngokuvamile ohlangothini lwe-drive yebhande (njengebhande lesikhathi noma uhlangothi lwebhande lejeneretha).
Isakhiwo Nezinto Ezisetshenziswayo
Izinhlobo ezivamile: Izivalo zikawoyela ezivame ukuba nohlaka (njengohlobo lwe-TC), eziqukethe uhlaka lwensimbi, izindebe zokuvala zerabha, kanye nesipilingi esiziqinisayo.
Izinto Ezivamile:
Irabha ye-Nitrile (i-NBR)
Irabha ye-Fluoro (FKM)
Irabha ye-silicone (VMQ)
I-Polytetrafluoroethylene (PTFE), njll.
Ibanga Lokumelana Nokushisa: Ngokuvamile -40°C kuya ku-180°C, lifanele indawo yokusebenza yenjini enokushisa okuphezulu nesivinini esikhulu.
Ukubonakaliswa Kwamaphutha
Amabala kawoyela noma ukuvuza kukawoyela endaweni yenjini noma engxenyeni engaphambili ye-crankshaft
Inani lamafutha elincishiswe ngendlela engavamile
Iphunga elishile lingatholakala lapho uqalisa injini ebandayo (ngenxa yokuconsa kukawoyela ezingxenyeni ezishisayo)
Iziphakamiso Zokufaka Esikhundleni
Uma ukuvuza sekutholiwe, kufanele kushintshwe ngokushesha okukhulu ukuze kugwenywe ukusebenza kwesikhathi eside okuholela ekungagcobi ngokwanele.
Inqubo yokufaka esikhundleni idinga ukusetshenziswa kwamathuluzi akhethekile (njenge-oil seal puller, umshini wokucindezela), futhi kuyadingeka ukuhlanza ubuso be-crankshaft, ukufaka inani elifanele lamafutha enjini ngaphambi kokufaka i-oil seal entsha.
I-crankshaft oil seal yangaphambili incane kodwa "iyi-invisible guardian" ebalulekile eqinisekisa ukusebenza okuthembekile kohlelo lokugcoba lwenjini.
Umsebenzi oyinhloko wesivalo samafutha sangaphambili se-crankshaft yemoto ukuvala ingxenye engaphambili ye-crankcase ukuvimbela ukuvuza kwamafutha enjini nokuvimba ukungcola ukuthi kungangeni.
Ukuvimbela Ukuvuza Kwamafutha: I-crankshaft oil seal yangaphambili ifakwe engxenyeni engaphambili ye-crankshaft (ngokuvamile ohlangothini lwe-pulley yenjini), futhi umsebenzi wayo oyinhloko ukuvala ngokuguquguqukayo i-crankshaft ejikelezayo, ukuvimbela uwoyela wenjini ukuthi ungavuzi kusuka ku-crankcase uye ngaphandle kwenjini, ngaleyo ndlela kugcinwe ukusebenza okuvamile kohlelo lokugcoba nokugwema ukungcoliswa kwamafutha kwengxenye yenjini.
Ukuhlukanisa Izingxenye Zokugcoba: Kuhlukanisa i-crankshaft egcotshwe kanye nezinye izingxenye zangaphakathi ezingxenyeni zangaphandle zokukhipha (njenge-pulley) ukuqinisekisa ukuthi uwoyela wokugcoba awuvuzi.
Ukuvimbela Ukungcola Kungangeni: I-oyili seal ingavimbela nothuli, udaka, umhwamuko wamanzi, njll., ukuthi ungangeni ngaphakathi kwenjini, ivikele ama-crankshaft bearings nezinye izingxenye ezibalulekile, futhi inciphise ukuguguleka.
Indlela Yokufeza Ukuvalwa: Kwakhiwa ifilimu encane kawoyela ocindezelayo oguquguqukayo phakathi kwendebe yesivalo sikawoyela kanye nobuso be-crankshaft obujikelezayo, obungavala uwoyela wenjini futhi bugcobe ubuso bokuxhumana phakathi kwendebe nomgodi, ngaleyo ndlela kufezwe ukuvalwa okusebenzayo okuguquguqukayo.
Izimbangela Ezivamile Zephutha Le-Car Crankshaft Front Oil Seal zingenye yezinkinga ezivamile zenjini, ezibonakala kakhulu njengokuvuza. Uma zingaxazululwa ngesikhathi, zingadala ukugcotshwa okubi kwenjini, ukwehla kwamandla, ngisho nengozi yokuzishayisa. Lokhu okulandelayo ulwazi oluyisisekelo olusekelwe kudatha yomphakathi yakamuva enegunya:
Izimbangela Ezivamile Zephutha
Izinkinga zekhwalithi yesivalo sikawoyela: Izinto zerabha zekhwalithi ephansi ezinokumelana okungekuhle kwamafutha, ukumelana nokuguguleka, noma ukusebenza okulwa nokuguga, ezivame ukuguquka, ukuqhekeka.
Ukufakwa okungafanele: Isiciko samafutha sitshekile, asikho endaweni yaso, noma asisebenzisi amathuluzi akhethekile, okuholela ekulimaleni kwezindebe noma ekugugeni okungalingani;
Ngesikhathi sokufakwa, izingxenye azihlanzwa, futhi ukungcola kuyaklwebha uphawu lwamafutha noma ubuso be-crankshaft.
Ukugqokwa Kwe-Crankshaft: Ubuso bentamo ye-crankshaft bunemihuzuko, ukujiya, noma ukujiya ngokweqile, okonakalisa ukulingana kokuvala ne-oyili.
Indawo yokusebenza kwenjini engavamile:
Ukusebenza kwesikhathi eside okushisa okuphezulu nomthwalo ophezulu kusheshisa ukuguga kwesivalo sikawoyela;
Amaphutha ohlelweni lokungenisa umoya lwe-crankcase abangela ukuba ingcindezi yangaphakathi ibe phezulu kakhulu, okubangela ukuthi uphawu lwamafutha lucindezelwe luvuleke.
Ukusetshenziswa kabi kwamafutha enjini: Ukusebenzisa izincazelo ezingezona ezangempela noma ezingacacisiwe zamafutha enjini, okuholela ekwakhekeni okubi kwefilimu yokugcoba futhi kwandise ukuguguleka kwesivalo samafutha.
Ukuguga kwemvelo: Njengoba impilo yokusebenza ikhula (ngokuvamile iminyaka engaphezu kwemi-5), irabha ilahlekelwa ukunwebeka futhi iqhume imifantu.
Ukubonakaliswa Kwephutha Okuvamile
Amabala kawoyela noma ukuvuza kukawoyela engxenyeni engaphambili yenjini (eduze kwe-pulley);
Ukusetshenziswa kukawoyela okusheshayo, kanye nezinga le-dipstick kawoyela lehla kakhulu;
Isibani se-alamu sokucindezela uwoyela siyakhanya ngemva kokuqala (ezimweni ezimbi kakhulu);
Uma ususa ipani likawoyela, amabala kawoyela amasha angabonakala eduze kwe-crankshaft.
Izixazululo
Shintsha izivalo zikawoyela ezisezingeni eliphezulu: Khetha imikhiqizo yomkhiqizo yokuqala noma ethembekile, uqinisekise ukuthi izinto zokwakha nosayizi kuyahambisana.
Izinqubo zokufaka ezijwayelekile:
Sebenzisa ithuluzi elikhethekile lokucindezela, ugcine uphawu lwamafutha luhambisana;
Ngaphambi kokufaka, faka inani elifanele lesithambisi esingesiphethiloli (ukuvimbela ukuthi isivalo sikawoyela singakhululeki);
Hlanza kahle indawo yokufaka ukuze uvimbele ukungcola ukuthi kungangeni.
Hlola futhi ulungise i-crankshaft:
Ukuguga okuncane kungapholishwa futhi kupholishwe;
Ukuguga okukhulu kudinga ukushintshwa kwe-crankshaft.
Hlola futhi uxazulule inkinga ohlelweni lwenjini:
Hlola ukuthi uhlelo lokungenisa umoya lwe-crankcase aluphazamisekile yini;
Qinisekisa ukuthi uhlelo lokupholisa lujwayelekile ukuze ugweme ukushisa ngokweqile kwenjini;
Sebenzisa uwoyela wenjini ohlangabezana nezidingo zomenzi.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
