Iyini uphawu lwamafutha lwangemuva lwe-crankshaft yemoto?
Isiciko samafutha sangemuva se-crankshaft yemoto siyingxenye ebalulekile yokuvala efakwe ekugcineni kwe-crankshaft yenjini, eduze nendawo yokuxhuma ne-gearbox. Umsebenzi waso oyinhloko ukuvimbela uwoyela wangaphakathi wenjini ukuthi ungaphumi ngaphandle nokuvimbela uthuli, umswakama kanye nokunye ukungcola ukuthi kungangeni. Umsebenzi oyinhloko
Uwoyela wenjini ovaliwe: Uvimbela uwoyela wokugcoba osesikhwameni ukuthi ungaphumi ngesikhala esiphakathi kwe-crankshaft kanye ne-cylinder block (noma i-transmission housing).
Ihlukanisa ukungcola kwangaphandle: Ivimbela isihlabathi, umhwamuko wamanzi, njll. ukuthi kungangeni ngaphakathi kwenjini, ivikele uhlelo lokuthambisa.
Igcina ukuqina kokugcoba: Iqinisekisa ukusebenza okuvamile kohlelo lokugcoba injini, igwema ukwehluleka kokugcoba, ukuguguleka kwenjini, ngisho nokushisa ngokweqile ngenxa yokulahlekelwa uwoyela.
Isakhiwo Nezinto Ezisetshenziswayo
Ngokuvamile kwenziwa ngerabha evikela ukushisa okuphezulu (njenge-fluororubber, irabha ye-nitrile) kanye nohlaka lwensimbi.
Yamukela ukwakheka kwesakhiwo sezindebe ezimbili. Esinye isiphetho sivala ngokuguquguqukayo ubuso obujikelezayo be-crankshaft, kanti esinye isiphetho sivala ngokuma imbobo yokufaka. Eminye imikhiqizo inezipilingi eziziqinisayo ukuze kuthuthukiswe umphumela wokuvala.
Ngesikhathi sokufakwa, kuyadingeka ukufaka kahle imbobo yesihlalo se-crankshaft. Ukulawula ukubekezelelana kuqinile (njengo-±0.03mm) ukuqinisekisa ukuvalwa okuthembekile.
Izinkinga Nemiphumela Evamile
Imiphumela yokuguga noma ukulimala:
Okuncane: Ukuvuza kukawoyela, okungcolisa i-clutch, i-flywheel, noma indawo yenjini.
Okubi kakhulu: Ukwehla kwevolumu kawoyela, okuholela ekungagcwalisi ngokwanele, okubangela umsindo wenjini ongavamile, ukushisa ngokweqile, ngisho nomonakalo omkhulu.
Ubunzima bokushintshwa: Kudinga ukuhlukaniswa kwe-transmission, ngomsebenzi oyinkimbinkimbi kanye nezindleko eziphakeme.
Isincomo Sokufaka Esikhundleni
Kunconywa ukusebenzisa izingxenye zangemuva noma zekhwalithi ephezulu. Izingxenye ezingezona ezangempela zingase ziphinde zivuze ngemva kwezinyanga ezimbalwa.
Ngesikhathi sokulungiswa kwansuku zonke, hlola amabala kawoyela. Uma kutholakala ukuvuza, kuphathe ngokushesha. Uma ungathanda ukwazi izindlela ezithile zokufaka esikhundleni samamodeli athile ezimoto (njengeMazda 3, Yuchai 6108, Cruze, njll.) noma amamodeli ahambisanayo ophawu lukawoyela, sicela unikeze imininingwane eyengeziwe.
Umsebenzi oyinhloko wesivalo samafutha sangemuva se-crankshaft yemoto ukuvala ukuxhumana phakathi kwengxenye engemuva ye-crankshaft yenjini kanye ne-gearbox, ukuvimbela ukuvuza kwamafutha okugcoba nokuvimbela ukungena kwezinto ezingcolisayo zangaphandle njengothuli nomswakama enjinini. Imisebenzi ethile yile elandelayo:
Ukuvimbela ukuvuza kwamafutha: Ukuqinisekisa ukuthi uwoyela wokugcoba osesikhwameni senjini awuvuzi usuka ekugcineni kwe-crankshaft uye ku-gearbox noma endaweni engaphandle, ngaleyo ndlela kuqinisekiswe ukusebenza okuvamile kohlelo lokugcoba.
Ukuvimbela ukungcola kwangaphandle: Ukuvimbela udaka, umhwamuko wamanzi, uthuli, njll. ukuthi lungangeni ekhabetheni, ukugwema ukuguguleka kwamabheringi nezingxenye zangaphakathi.
Ukugcina ingcindezi kawoyela kanye nokugcotshwa: Ngokuvala okuguqukayo (umlomo wesivalo sikawoyela uthintana ne-crankshaft ejikelezayo) kanye nokuvalwa okungaguquki (unqenqema lwangaphandle lwesivalo sikawoyela oluhambisana nokuphazamiseka nomgodi wokufakwa), kwakha isithiyo sokuvala esisebenzayo ukuqinisekisa ukusebenza kahle kokugcotshwa kwenjini.
Uma uphawu lwamafutha olungemuva lwe-crankshaft luguga noma lonakele, luzobangela ukuvuza kwamafutha, okungaholela ekungagculisi injini ngokwanele, ekushiseni ngokweqile, ngisho nasekuhlulekeni okukhulu kwemishini. Ngakho-ke, uma kukhona ukuvuza kwamafutha, kuyadingeka ukulishintsha ngesikhathi.
Ukufaka uphawu lwamafutha lwangemuva lwe-crankshaft akuyona into enkulu yokulungisa; kuyinto yokulungisa evamile futhi ngokuvamile ayidingi ukuhlakazwa kwezingxenye eziyinhloko zenjini.
Ukwehluleka kwesivalo samafutha sangemuva se-crankshaft yemoto kuyinkinga evamile kodwa ebalulekile yokuvala injini. Uma ingaxazululwa ngesikhathi, ingabangela ukugcotshwa okunganele, ukuguguleka kwenjini okusheshayo, ngisho nomonakalo omkhulu. Lokhu okulandelayo yizifinyezo zolwazi olubalulekile:
Izimbangela ezivamile
Ukuvuza komphetho: Umlomo wesivalo samafutha uyaguga, ugugile, isiphethu siyawa, noma indlela yokufaka ayilungile, okuholela ekwehlulekeni kwesivalo.
Ukuvuza kwe-Periphery: I-oil seal ikhubazekile, ikhululekile, ithambekile, noma iyaklwebheka, ikakhulukazi ngenxa yokungalingani kwendawo ecindezelwayo kanye nendawo yokufaka, okubangela amandla angalingani endebeni.
Izinto ezingezona ezekhwalithi:
Ukufakwa ngaphandle kokusebenzisa amafutha angenawo uphethiloli, okwenza uphawu lwamafutha lukhululeke futhi luwe;
Uwoyela wenjini odlulele noma owonakele, okubangela ukucindezeleka okukhulu ku-crankcase;
Izinga lokushisa eliphezulu kanye nezimo zokusebenza ezinzima kusheshisa ukuguga kwe-oyili seal .
Umthelela wephutha
Ukusetshenziswa kawoyela okwandisiwe, ukwehla kwezinga likawoyela, okuthinta umphumela wokugcoba;
Ukuguguleka kwenjini okusheshayo, ukuntuleka kukawoyela isikhathi eside kungaholela ekulimaleni okukhulu njengokubanjwa kwesilinda kanye nokubanjwa kweshaft;
Ukungcoliswa kukawoyela we-chassis, okubeka izingozi zokuphepha.
Iziphakamiso zokuphatha
Nquma ngokushesha izinga lokuvuza kwamafutha:
Ukuvuza okuncane: Awukwazi ukukufaka esikhundleni okwesikhashana, kodwa kudingeka uhlole njalo izinga likawoyela bese ugcwalisa kabusha;
Ukuvuza okukhulu (njengokuvuza kwamafutha, ukuqongelela kwamafutha epanini lamafutha): Kufanele kulungiswe ngokushesha okukhulu.
Izinyathelo eziphuthumayo (zohambo olufushane kuphela):
Engeza inani elifanele lamafutha enjini ku-crankcase ukuze ugcine ukuthambisa;
Zama ukuvala okwesikhashana: Susa isembozo sokugcina esiyinhloko bese usebenzisa ingxube yentambo ye-asbestos egcotshwe ngamafutha kanye nomugqa we-asbestos we-graphite ukuze uvale okwesikhashana .
Uhlelo lokulungisa olusemthethweni:
Shintsha uphawu lwamafutha lwangemuva lwe-crankshaft: Kudinga ukuhlakazwa kwebhokisi lamagiya, futhi kunconywa ukuthi kusetshenziswe uchwepheshe ochwepheshe ;
Sebenzisa izingxenye zasefektri zokuqala kanye nezinto zokugcoba ezingezona ezephethiloli ukuze ufake ukuqinisekisa ukusebenza kahle kokuvala ;
Uma kubangelwa uwoyela wenjini oweqile, izinga likawoyela kufanele lehliswe liye ezingeni elijwayelekile kuqala.
Iziphakamiso zokuvimbela:
Ukulungiswa njalo, ukushintshwa kwamafutha enjini ngesikhathi esifanele;
Gwema ukusebenza isikhathi eside ngesikhathi sokushisa okuphezulu kanye nomthwalo ophezulu;
Uma ushintsha uphawu lwamafutha, qiniseka ukuthi usebenzisa amathuluzi akhethekile ukuqinisekisa ukufana kokufakwa .
Isikhumbuzo Esibalulekile: Ungalibazisi ukuvuza kukawoyela kwesivalo sikawoyela sangemuva isikhathi eside; noma ngabe kungathinti ukushayela okwesikhashana, kuzolimaza kancane kancane isikhathi sokuphila kwenjini.
Kunconywa ukuthi uye esitolo se-4S noma esitolo sokulungisa sochwepheshe ukuze uthole ukuxilongwa nokwelashwa.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
