Isimiso sokusebenza se-fan viscous coupling
Okuqukethwe
Ukuhlangana kwe-viscous fan kungenye yezingxenye ezingaziwa kakhulu zohlelo lokupholisa injini.
Yini ukuhlangana kwe-viscous fan
Kusetshenziswa izindlamu zabalandeli ezimotweni (izimoto namaloli) enenjini efakwe kude, ikakhulukazi izimoto ezihamba ngamasondo angemuva. Bamba liyadingeka ngesivinini ongaphakeme futhi idle ukulawula lokushisa. Ifeni elingalungile lingadala ukuthi injini ishise kakhulu ngesikhathi somgwaqo ongenzi lutho noma osindayo.
Uphi
I-viscous fan clutch itholakala phakathi kwepulley pulley nerediyetha futhi yenza le misebenzi elandelayo:
- Ilawula isivinini sabalandeli sokupholisa injini;
- Isiza ekusebenzeni kahle kwenjini ngokuvula ifeni lapho kudingeka;
- Yehlisa umthwalo enjini.
Ukuqinisa ukuhlanganiswa
Kuphakathi ukuthi ukuhlangana kubekwe kushaft esine-flanged egxunyekwe ku-pulley yepompo, noma kungenjalo ingafakwa ngqo ku-shaft yepompo.
Umgomo wokusebenza kwesihlanganisi se-viscous
Ukuhlanganiswa kwe-viscous kusekelwe enzwa ye-bimetallic etholakala ngaphambili kwe-viscose fan. Le nzwa iyanweba noma izinkontileka, kuya ngezinga lokushisa elidluliswa nge-radiator. Le ngxenye ehlakaniphile ithuthukisa ukusebenza kahle kwenjini ngokulawula isivinini se fan yenjini nokunikezela umoya obandayo.
Amazinga okushisa abandayo
Inzwa ye-bimetallic icindezela i-valve ukuze uwoyela ngaphakathi kokuhlangana aqhubeke egumbini lokugcina amanzi. Ngalesi sikhathi, i-viscose fan clutch ayisebenzi futhi ijikeleziswa cishe ku-20% wejubane lenjini.
Ekushiseni okusebenzayo
Inzwa ye-bimetal iyanweba, ijikelezisa i-valve futhi ivumela uwoyela ukuthi uhambe kulo lonke ikamelo uye emaphethelweni angaphandle. Lokhu kudala i-torque eyanele yokushayela ama-fan blades kumajubane wokusebenza we-injini. Kuleli qophelo, i-viscous fan clutch ibamba futhi ijikeleze cishe i-80% yesivinini senjini.
Yini okungaholela ekuhlanganisweni kwe-viscous okuyiphutha?
Lapho ushintsha iphampu, kuhlala kunconywa ukuhlola isimo se-viscous fan clutch. Ukuhlangana okonakele kuzothinta ngqo impilo yepompo. I-viscous fan clutch engalungile ingahlala inamathele endaweni ebandakanyekile, okusho ukuthi izohamba njalo ngejubane le-80% lenjini. Lokhu kungaholela ekuwohlokeni ngamazinga aphakeme omsindo nokudlidliza, kwakheke umsindo omkhulu we-vortex njengoba i-rpm yenjini inyuka futhi ukusetshenziswa kukaphethiloli kuyanda.
Ngakolunye uhlangothi, uma ukuxhumana kwe-viscous fan kungaphumeleli endaweni evaliwe, ngeke kuvumele umoya ukuthi udlule ku-radiator. Lokhu-ke kuzoholela ekutheni injini ishise ngokweqile lapho inqubo yokupholisa iyeka.
Izimbangela zokwehluleka
- Ukuvuza kukawoyela ku-clutch, ukunqanyulwa kwe-fan clutch;
- Inzwa ye-bimetallic ilahlekelwa yizakhiwo zayo ngenxa ye-oxidation engaphezulu, okwenza umkhono ubambeke;
- Ukuthwala ukungasebenzi kahle, yize kungaqabuki kwenzeke uma i-viscous fan clutch ingashintshwanga ngemuva kwemayela elide. Lokhu kuholela ekuwohlokeni kwesimo sezindawo.
Viscous elihlangana ukusebenza inzwa
Inzwa ye-bimetallic ilawula ukusebenza kwe-viscose clutch. Ngokuyinhloko, kunezinhlobo ezimbili zezinhlelo zokuzwa nge-bimetallic: ipuleti nekhoyili. Bobabili basebenza kumgomo ofanayo njengoba kuchaziwe ekuqaleni.
Umehluko kuphela ukuthi njengoba ikhoyili inweba futhi izivumelanisa ukujikeleza ipuleti lokujikeleza, izinkontileka zebimetal kanye nezimo eziguqukayo. Lokhu kuhambisa ipuleti lesilayidi futhi kuvumela uwoyela ukuthi asuke egumbini lamachibi angene emgodini.
Ividiyo: ungakuhlola kanjani ukuhlangana kwe-viscous
Imibuzo nezimpendulo:
I-viscous fan drive isebenza kanjani? I-rotor yayo ixhunywe ku-crankshaft pulley isebenzisa i-belt drive. I-disk ene-impeller ixhunywe ku-rotor ngokusebenzisa uketshezi olusebenzayo. Lapho uketshezi lushisa, luyaqina futhi i-torque iqala ukugeleza kudiski eqhutshwayo.
Ukuqonda kanjani ukuthi ukuhlangana kwe-viscous kunephutha? Okuwukuphela kwesibonakaliso sokuhlangana okungalungile kwe-viscous ukuthi injini ishisa ngokweqile futhi ifeni ayijiki. Kulokhu, i-gel ingase iphume, i-clutch ingase i-jam (imisindo engaphandle izwakala).
Isetshenziselwani i-viscous coupling? I-viscous coupling yakhelwe ukuxhuma okwesikhashana isethi eyodwa yamadiski kusethi ehamba phambili. Ukuhlangana kwe-viscous kwefeni yokupholisa kunikeza ukupholisa kurediyetha. Kusetshenziswa indlela efanayo ezimotweni ezidonsa ngawo wonke amasondo.
ЧYini i-hydraulic fan clutch? Kuya ngezinga lokushisa lesipholisi enjinini, sishintsha isivinini sefeni. Uma ishisa, i-clutch inyusa isivinini se-fan.
