Crankcase Somuhlwa System: A izinhlobo kudivayisi, izimiso yokusebenza

Okwamanje, naphezu ukuthuthukiswa ngokushesha ubuchwepheshe ukudala pair uphawu ngokuphelele friction izingxenye - isilinda, futhi piston izindandatho - akunakwenzeka. Ngakho-ke ekugcineni ithola ukusebenza imikhiqizo amandla omlilo e injini.

kudlule amagesi sump crankcase ngokusebenzisa izindandatho piston, okuyizinto eseduze amasilinda alengayo. Ngenxa yalokho, ukushisa sisuswa nakakhulu sokuphila selithi lubricating liquid Kumiswa nokucindezelwa ngokweqile kuwo wonke uphawu block. crankcase ukupholisa ithiya ngokweqile crankcase ingcindezi.

ukuthuthukiswa amadivayisi

Ekuqaleni lo mshini lalithé: kusukela crankcase elula isiphetho tube, ikhiqiza amagesi emkhathini kanye nokungcolisa ke. Kodwa imithetho ngesikhathi kukhishwa umoya ovela izimoto kanzima some. Ngakho-ke, uhlelo crankcase ukupholisa yasungulwa ngaphakathi yizimboni.

Mshini isimiso yesenzo

Esikhathini kwindlela Uhlelo okwamanje eyaziwa, amagesi hhayi kuphela asakazeka emkhathini. Bathunyelwa motor ngokusebenzisa tube ikhishwe sump, kube komunye umkhawulo okuyinto ixhunywe le ezininginingi eyanele. Kusuka lapho amagesi baqondiswa ekamelweni amandla omlilo. Flash iphuzu wabo uyaphakama kanti enye ingxenye yaba kukhishwa indlela qeda. Kuphela ingxenye encane yalezi amagesi futhi engena crankcase. Njengoba inqubo ithatha indawo ngaphandle kokuphazamiseka.

Izinhlobo sump recirculation uhlelo

Kunezinhlobo ezimbili izinhlobo zezimiso:

• ongaphandle;
• evaliwe.

Esimweni sokuqala, njengoba kuchazwe ekuqaleni kwalesi sihloko, amagesi ngepayipi emkhathini nje. Esikhathini yesibili basuke ukusivumela komsele eyanele. Kuvaliwe crankcase ukupholisa uhlelo: Vaz futhi "Lada", BMW futhi "Mercedes", amaJapane futhi amaMelika ikakhulukazi esetshenziswa njengamanje.

Ngaphezu kwalokho, izinhlelo ivaliwe ayatholakala nge-AC noma i-DC zamanje. Uhlobo lokuqala uyakwazi ukulawula ngokunembile sump recirculation. It luyehluka kuye ngokuthi inani igesi engenayo.

kudivayisi

Ngesikhathi phezulu isihlukanisi iyona crankcase ukupholisa uhlelo futhi ngaphakathi uwoyela - the kugqame. umsebenzi Its ukukhulula umoya ovela izinhlayiya uwoyela. PCV uwoyela isihlukanisi has kundawo ukuze komsele. Ngo operation evamile injini crankcase njalo cleaner ezithile kumele kwenzeke. Valve ungasebenza embodiments ezintathu.

Ephoqelekile crankcase uhlelo ukupholisa: Valve

Ake sicabangele kafushane zontathu lezi ongakhetha.

kwakhiwa 1. Ukuze mpintsha is by ingcindezi ongaphakeme mbar 500 kuya 700. crankcase ukupholisa uhlelo, lokhu akuyikuma. Futhi piston ngaphansi isenzo cleaner, uvala valve.
2. Uma mpintsha ivuliwe ngokugcwele, ingcindezi kukhona elilingana asemkhathini noma ngaphezulu. Lapho ufika 500-700 mbar piston uvala valve for ukudlula amagesi.
3. Esikhathini isikhundla maphakathi inikezwa yi evamile ingcindezi piston.

Uma umsebenzi valve sizodingida imibuzo, kulula ukuhlola ukuseviswa. Kuze kube yimanje, idling entanyeni, okuyinto ugcwele ngamafutha, wafaka ephepheni. Uma eyehlisiwe lokungawo futsi navuswa kanye ukuhamba diaphragm, valve kuyinto serviceable.

ukusebenza evamile angaqinisekiswa ngezinye izindlela. Kwimodi engenzi lutho, susa hose ukupholisa ukuvala umunwe kufanele bazizwe ukuncela.

Ingcindezi ekunciphiseni valve

Uma injini esebenza ngesivinini, edonsa ezininginingi ingcindezi ekhona, ukuthi inenani ilingane asemkhathini noma idlula ke. Kulokhu, amagesi crankcase uthola isikhathi eside. Uma itheku has a turbocharger, cleaner ngeke ibe nkulu kakhulu futhi kufanele kube nokulinganisela.

Kuze kube yimanje, inikeza a ingcindezi ukwehlisa valve, nesebenzela in the ezininginingi eyanele lapho valve liyavuleka. Mechanism ehlanganisa ulwelwesi futhi isiphethu ufakwa izindlu plastic, lapho kukhona nokufakwa itheku futhi yokuxhuma.

ingcindezi Umsebenzi ekunciphiseni valve

Ngo evamile low-ingcindezi entwasahlobo ukulayishwa. Ulwelwesi ophakamayo kanye amagesi ziyadlula ngokukhululekile.

Zacindezelwa encishisiwe, diaphragm lehliselwa futhi ivale esidayisa ngokumelene isenzo entwasahlobo. Khona-ke amagesi ziqala ukuhamba ephumayo - isiteshi nge ukuvulwa ulinganiswe.

Ngeshwa, esebenza kahle kulolu hlangothi, uhlelo crankcase ukupholisa kudala inkinga nabanye. Ukuza aphume Pallet, amagesi uthathiwe lubricating izinhlayiya, ngaleyo ndlela elonakalisayo uhlelo eyanele. Ngaphezu kwalokho, imali Laphezu iziteshi ephumayo, futhi imininingwane valve bavuselele. Lokhu kuholela ukuvaleka komgudu futhi kungabangela eziyimbangela yezinkinga ezizuzwa e umjovo. Uma iris is bagibele, lo ukusetshenziswa uwoyela kuyokhula. Khona-ke kubalulekile ukuba ukushintsha valve.

Futhi ungakhohlwa mayelana neminye imininingwane ebalulekile, kanye nesikhathi ukushintsha hose crankcase ukupholisa - lokhu ngokuvamile kwenziwa ngokuhlanganyela valve recirculating. Uma kungenjalo, ungase uqhekeke futhi amakhefu.

Ukuze ugweme ukulungiswa ebizayo, kubalulekile ukuba sinake izindawo abasafufusa ku injini zamanzi, badle kakhulu ukudla zokubasa kanye lubricating operation uketshezi engazinzile yenjini. Uma isikhathi ukushayela esikhungweni sesevisi, inkinga ziyoxazululwa ihlumela, waze akazange abangele umonakalo omkhulu iyunithi.
