Iqela piston: izixhobo kunye nezixhobo

iqela piston - iqela amakhonkco piston uphawu. Kanye njengokuba kuquka isikhonkwane piston kunye neenkcukacha obandayo. Iyafuna kucingwe ngokuqeshwa indlela.

Ngenxa bohluke uxinzelelo igesi kwaye ayihambi ngokusebenzisa intonga yokungena kwi crankshaft. Nje ngenxa kule nqubo, njengoko iqela piston ke, isithuba cylinder ngaphezu piston ivaliwe. Ngaloo ndlela uya kukhuselwa zidibane ngokugqithiseleyo kunye crankcase yokuqaba oyile kunye neegesi. Olu phawu ibaluleke gqitha ukusebenza kakuhle injini. Malunga koko, koko imeko zobugcisa, yena kugwetywa amandla uphawu. Umzekelo, kwi-injini yemoto akavumelekanga ukuba ukusetyenziswa oyile yaba ngaphezulu kwesithathu pesenti amafutha.

iqela piston uphumeza umsebenzi kwayo kwiindawo ngqwabalala. Kungenxa yoko le nto iinkcukacha zale ndlela babe namandla eliphezulu thermal, yaye oku kuthathelwa ingqalelo xa eziphathekayo Kukhethwe uyilo kubo. Ezi zinto ke ngokuqhelekileyo uyilo abenzi, banikwa uhlobo injini kunye indawo (izithuthi, zokubhala, idizili, uhlobo, njalo njalo). Noko ke, kumbutho usahleli efanayo. Ngoko ke, kufuneka uqale uqonde, yintoni iqela piston.

Umboko piston inxenye (isikhokelo) ukwabizwa ngokuba isondo piston. Kuyinto ngaphakathi namanzi, ukuba bemba imigodi piston pin. Ungqameko olungezantsi isondo isoloko isetyenziswa njenge isiseko lobugcisa yonyango piston. Kungenxa yale yomqala inikwa nge yazala. Ukongeza, iindonga isondo kusekho ziyifumanisa amandla xi osecaleni, kwaye yandisa ukukhuhlana lwabo udonga cylinder kwaye yandisa lombhobho zokufudumeza piston.

Intloko piston ithwala amakhonkco piston kwaye ezantsi. Emseleni kwezinto umgqobho kubonakala apho oyile ethambisayo xa iqatyiwe kangangokuba akazange kuwa ngempazamo kwigumbi yokutsha. ezantsi lwakhe - le yenye iindonga kwegumbi. Kuthatha iigesi koxinzelelo olukhulu. kanye emazantsi inokuba tyaba, phakathi, khaxa okanye zilungiswa. Kwakhona, ukwakheka kwalo ikhethiwe kuthathelwa ingqalelo uhlobo injini yokutsha gumbi.

Akunakwenzeka ukuba ukubalula kwindlela njengeqela cylinder-piston. Eyona iziphene ephambili block cylinder - eyonakele, chipped afake. Ezi amaphutha kusekwa emva kokuba uhlolo olunzulu, uvavanyo xi zomlinganiselo njengesilinda. Kule nkqubo, kwi ibhloko ofuna ukufaka entloko okanye alahle-yentsimbi ipleyiti (esisinyanzelo zerabha gasket). Ngokuqhelekileyo, eli qela iyahluka ubushushu-resistant zentsimbi kunye neoli okupholisa, endiwenziweyo ngeendleko ejikeleza iyonke inkqubo ukuthambisa ajikeleze kule injini main idizili. Ukuba ibonelele ngeendlela inkathalo elungileyo neoli ezikumgangatho ophezulu, kunokwenzeka ukuba ngokulula ukwandisa ubomi Pistons nesilinda.

Ukanti enye indlela - kokuxhuma intonga kunye piston qela. Le piston - kunye cast aluminiyam. Umphezulu engaphandle ngokumila inzima kakhulu. Piston pin - nomgodi ezenziwe ngentsimbi, ukuba isimahla ukujikeleza emkhonweni ye kokuxhuma intonga kunye piston nabaqashi. A ring piston eyenziwe cast yentsimbi. Kwaye, kakade, ngentonga - nensimbi zomgunyathi. Xa intloko eliphezulu unalo kwisingxobo ezenziwe ngomxube ngentsimbi nobhedu, nto leyo iba nefuthe entle iqela lonke.
