Iyini uphawu lukawoyela lwe-crankshaft lwezimoto
I-crankshaft oil seal iyithuluzi lokuvala elisetshenziswa ezingxenyeni zangaphambili nangemuva ze-crankshaft yenjini. Umsebenzi walo oyinhloko ukuvimbela ukuvuza kwamafutha okugcoba nokuhlukanisa indawo yokugcoba endaweni yokukhipha amandla ezingxenyeni zokudlulisa, ukuqinisekisa ukusebenza okuvamile kwenjini. I-Youdaoplaceholder0 imeleli ejwayelekile yezimbobo zamafutha, ngokuvamile ezenziwe ngezinto ezifana nerabha, futhi ifakwe engxenyeni engaphambili (ohlangothini lwe-pulley) kanye nangemuva (ukuxhumana ne-transmission) ye-crankshaft. Uma isigugile noma igugile, izobangela ukuvuza kwamafutha futhi ithinte ukusebenza kwenjini.
Incazelo kanye nomsebenzi
I-crankshaft oil seal iyisici sokuvala esiklanyelwe ngqo uhlelo lwe-crankshaft lwezinjini. Umsebenzi waso oyinhloko ukuvimbela uwoyela wokugcoba (uwoyela wenjini) ukuthi ungaphumi endaweni ye-crankshaft futhi ngesikhathi esifanayo uvimbele uthuli lwangaphandle kanye nokungcola ukuthi kungangeni ngaphakathi kwenjini. Umklamo waso uqinisekisa ukuthi indawo yokugcoba yezingxenye zokudlulisa (njenge-bearings) ihlukanisiwe neyezingxenye zokukhipha (njenge-crankshafts), ukugwema imfucuza noma ukungcola kowoyela wenjini kanye nokugcina ukusebenza kahle kwenjini.
Indawo kanye nesakhiwo
Izimbozo zikawoyela ze-crankshaft zihlukaniswa ngezinhlobo ezimbili ngokuya ngezikhundla zazo zokufaka:
I-Youdaoplaceholder0 crankshaft front oil seal : Itholakala kolunye uhlangothi lwe-pulley yenjini, ivala indawo yokungena yangaphambili ye-crankshaft ukuvimbela uwoyela wenjini ukuthi ungaphumi egumbini lenjini.
I-Youdaoplaceholder0 crankshaft oil seal yangemuva : Itholakala ekuxhumaneni phakathi kwe-crankshaft ne-transmission, ivimbela uwoyela wenjini ukuthi ungene ku-transmission futhi ivikele uhlelo lokudlulisa.
Isakhiwo esijwayelekile isivalo samafutha se-TC (uhlobo lwezindebe ezimbili), esakhiwe ngohlaka lwensimbi olumbozwe ngerabha. Udebe lwangaphakathi luthinta ubuso be-crankshaft ukuze kwakheke uphawu, kuyilapho udebe lwangaphandle lunamathele kubhulokhi yenjini futhi lufakwe isipilingi sokuthuthukisa ingcindezi yokuvala.
Izinto zokwakha kanye nemibuzo evame ukubuzwa
Izinto ezivamile zifaka irabha ye-nitrile, irabha ye-fluorine kanye nerabha ye-silicone, okudingeka imelane namazinga okushisa aphezulu, ukugqwala kwamafutha enjini kanye nokungqubuzana kokujikeleza komgodi. Izimbangela ezivamile zokwehluleka zifaka:
I-Youdaoplaceholder0 Ukuguga nokuguguleka : Amazinga okushisa aphezulu esikhathi eside kanye nokunyakaza kwemishini kubangela ukuthi irabha iqine futhi unqenqema lwakamuva luguge.
I-Youdaoplaceholder0 Ukufakwa okungafanele : Ukusetshenziswa okungalungile kwamathuluzi noma ukugoba okuqinile ekugcineni komgodi, okubangela ukuklwebheka noma ukuguquka komlomo.
I-Youdaoplaceholder0 Izici zangaphandle: Uwoyela wenjini osezingeni eliphansi usheshisa ukugqwala, noma ukucindezela okukhulu kwe-crankcase kulimaza izivalo.
Iphutha libonakala njengokuvuza kukawoyela, okubangela ukugcotshwa okunganele kwenjini, ukuncipha kwamandla noma ukungcola kwegiya. Kudingeka kushintshwe ngesikhathi.
I-crankshaft oil seal yemoto iyisici somshini esitholakala ngaphambili nangemuva kwe-crankshaft yenjini. Imisebenzi yaso eyinhloko ihlanganisa:
Vimbela ukuvuza kwamafutha enjini
Umklamo wokuvala uvimbela uwoyela wenjini ukuthi ugelezele ngaphandle kwenjini noma ngaphakathi kwegiya, okuvimbela ukusebenza okuvamile kohlelo lokugcoba injini ukuthintwa ukuntuleka kwamafutha enjini.
Ingxenye yokudlulisela ukwahlukaniswa
Hlukanisa izingxenye zenjini ezidinga ukugcotshwa ezingxenyeni ezikhipha amandla ukuqinisekisa ukusebenza okuzimele kohlelo lokujikeleza uwoyela wokugcoba futhi uvimbele izindlela zangaphandle ezifana nokudluliswa komoya ukuthi zingaphazanyiswa uwoyela wenjini.
Vikela imvelo yangaphakathi
Vimbela uthuli kanye nemfucumfucu ukuthi ingangeni ngaphakathi kwenjini, gcina indawo yokuthambisa ezinzile ukuze kube nezingxenye ezinembile, futhi unciphise ukuguguleka noma ukungasebenzi kahle okubangelwa ukungena kwezinto zangaphandle.
Isimiso sokuvala
Umphumela wokuvala ugcinwa ngokubambisana ngokuvala okuguquguqukayo (kusetshenziswa ifilimu kawoyela ukuze kutholakale ukugcotshwa koketshezi) kanye nokuvala okungaguquki (ukuqina kwerabha okuvimba ingcindezi yangaphandle) phakathi kwendebe yesivalo sikawoyela kanye nejenali ye-crankshaft.
