Car uhlelo Lubrication Engine

imoto uhlelo Lubrication yakhelwe ukunciphisa friction, ukugqoka doti ukususwa kanye nokupholisa evele. kukawoyela ku igebe phakathi Ixhumana ne (bezihlikihla) iyabonakala - uMbhalo bese piston - motor kwandisa kokucindezelwa bese isihumusha enkompolo ayazika.

Emafutheni asetshenziselwa ohlelweni Lubrication, okwethulwa izidingo ezahlukene. Kufanele abe viscosity Inkomba ezithile, uthele iphuzu ubuncane, okusezingeni eliphezulu umthamo Thermo-oxidative, flashpoint esiphezulu. Ngaphezu kwalokho, igrisi kumele kube inombolo ehlukile ubuncane coke. It kufanele ahlanze - kungabi ukungcola (alkalis, acid yezimbiwa, isibabule, amanzi) kanye nezinye admixtures lokukhanda.

Lezi zimfuneko ezivumelana izinto ethathwe uwoyela. Kuyinto evamile nokuba ngempela, futhi zokwenziwa amafutha. Noma kunjalo, iqhathaniswa amaminerali, sinokubaluleka okukhulu, kodwa ngesikhathi esifanayo, ubadlula ngekhwalithi.

Engine Lubrication uhlelo inikeza izinketho eziningana nokulethwa uwoyela. Material kungenziwa bondliwa amandla adonsela phansi, ecindezelekile noma by sishaye. Ekuklanyweni izimoto zesimanje, njengoba umthetho, zonke izinhlobo kukawoyela. uhlelo okunjalo kwezinkolo kubizwa ngokuthi "elihlangene injini Lubrication uhlelo." Kulokhu, ngokuvamile, amafutha akusho buthelela ezansi ngalo ingaphakathi, lapho ukujikeleza crank wenziwa. Indlela kuhlanganiswe luvame kakhulu ekwakhiweni ezine-unhlangothi izinjini, okuyinto ukusebenzisa uhlelo kwegazi ne ezomile sump Lubrication.

Amafutha kusukela crankshaft (crank izikhonkwane) apertures Special kungenzeka yanikezwa piston pin noma induku isiteshi wafutha phezu kodonga motor isilinda iziteshi ukuqondana kwezinto crankpin nokuxhuma induku. Ngakho, indlela sishaye uwoyela kungenziwa yanikezwa Cams camshaft endawni yayo ngezansi. Lapho endaweni ukuvuza bezihlikihla contact izingxenye ukuthi nivame sicindezelekile, le igrisi ihlinzekwa kungxenye isikhathi (tappets, valve stem induku, idrayivu chain) amandla adonsela phansi. Isipina crankshaft iphula amathonsi uwoyela, futhi kwakha "inkungu." Lokhu kusiza ukunciphisa izinkinga yokuxhumana.

Ukuze ngamafutha, lawo akhishwa kumelwe ahlangabezane nezimfuneko kunalokho elawula ukuhlanzeka. Kule ndaba, injini uhlelo Lubrication futhi ifakwe eziningi izihlungi.

On futha maslozabornike qala ulungise ngokuvamile Mesh zokuhlunga. Ngaphezu kwalokho, kunezindlela eziningana yokuhlanza yilezi:

1. Zonke amafutha kungenziwa yanikezwa uhlelo Lubrication ngokusebenzisa lemifanekiso. inqubo okunjalo kwezinkolo kubizwa ngokuthi ngokugcwele ukugeleza yokuhlanza.
2. Kuncike kanye ukuhlanzwa olungaphelele uwoyela. Kulokhu ethile uwoyela iqondiswa esuka epompeni noma engxenyeni isisefo isiteshi parallel a abakhwabanisi okwengeziwe sump.

Engine uhlelo Lubrication futhi ifakwe amadivaysi zidizayinelwe ukugcina elikhulu yesistimu yokusebenza lokushisa, kanye nokunikeza operation ikumodi eziphuthumayo. Amapharamitha eziyisisekelo ngokuchaza operation zihlanganisa izinga lokushisa nokucindezelwa. Ngokuphathelene uhlobo ukwakhiwa motor kunqunywa futhi elikhulu ingcindezi inkomba (ngaphakathi 1-8 kg / cm2).

Futhi, umkhawulo amagugu zinqunywa ngokuhambisana imodi injini yokusebenza. Linikeza ingcindezi ebambe phansi kwengcindezi ekunciphiseni valve. Le mininingwane ikusiza ukuthi ubeke umkhawulo ingcindezi isibalo esidingekayo. Ukufakwa valve wenziwa emgqeni main noma futha uwoyela ngokwawo.

Uma kwenzeka ukwehluleka esigcwele ukugeleza isihlungi inikezwe ukwakhiwa valve dlula. It ivumela uwoyela olunikezwe zokuhlunga.

Ukulondoloza umbuso ezishisayo efanele olunikezwa ukudluliswa ingxenye uwoyela kusiteshi ekhethekile kurediyetha ukupholisa ngu futha.
