TEMA:Samohodni pneumovaljci
1.0.Uvod
Potrebe firmi za stalnu izgradnju i obnovu zemljanih radova dovode do sto masovnijeg koriscenja valjaka sa
pneumaticima.Valjak na pneumaticima(gumenjak) je vrsta samohodnog valjka na gumenim
tockovima.Njegova osnovna primena je zbijanje tla.Zbija gnjecenjem sto je kombinacija zbijanja u smeru
kretanja i upravno na smer kretanja pneumatika.Osim statickog nacina zbijanja,ova vrsta valjaka moze vrsiti
zbijanje I putem vibracija.Proizvodnja ove vrste valjaka je pocela oko 50-tih godina,medjutim njihova
proizvodnja se masovno povecala zadnjih 20-tak godina.Jedna od vodecih firmi danas za proizvodnju
pneumatskih valjaka je Caterpilar.Za 2008 goginu Caterpillar je imao rekord prodaje I prihod od 51.324
milijarde dolara,sto je 14% vece od 2007 godine.Ova vrsta valjaka je dozivela veliku proizvodnju zadnjih
godina.Pored Caterpilara,vaznu ulogu u proizvodnji imaju i ostale firme kao sto su:Bomag,Komatsu,Hamm
itd.

2.1.Pogonski uredjaj
Pogonski uredjaj samohodnih pneumovaljaka je:dizel motor.Dizel motor je motor sa unutrasnjim
sagorevanjem koji koristi toplotu kompresije da iniciraju paljenje da se spali gorivo,koji se ubrizgava u
komoru za sagorevanje.Valjak tipa PC 300C,sadrzi dizel motor Caterpilar 3054C.
Karakteristike motora:Sto se tice samog motora,on je cetvorotaktni,tj. cetvorocilindricni.Ovaj motor
zadovoljava zahteve za emisijom EU Stage II.Opremljen je izduvnim loncem sa hvatacem varnica.

Sistem za gorivo sa unutrasnjimsagorevanjem:Sistem za gorivo sa direktnim ubrizgavanjem bez
podesavanja obezbedjuje pojedinacno odmeravano direktno ubrizgavanje goriva pod visokim pritiskom radi
obezbedjivanja maksimalne efikasnosti.
Hladnjak ulja:Hladnjak motornog ulja odrzava motor u radu ohladjenim i odrzava integritet ulja.
Uljna pumpa:Ona je postavljena jako nisko i sluzi za obezbedjivanje brzeg podmazivanja pri startovanju.
Visok odnos radne zapremine prema snazi:On osigurava dugovecnost i izuzetnu pouzdanost.
Grejac ulaznog vazduha:On pomaze startovanje pri veoma hladnom vremenu.
Filteri goriva i odvajac vode:Dvostruki filteri goriva i odvajac vode pruzaju superiornu zastitu za sistem sa
jedinicnim ubrizgavacima.
Zahtevi za emisijom izduvnih gasova:Ovaj motor zadovoljava zahteve za emisijom Direktive EU 97/68/EC
Stage II.
2. Dizel motori bi u buducnosti morali da ispunjavaju EVRO 6 norme.
Deklarisana neto snaga motora je snaga koja je raspoloziva na z zamajcu kada je motor opremljen
ventilatorom,precistacem vazduha izduvnim loncem I alternatorom.Svi modeli dizel motora imaju suvi
precistac vazduha sa dvostrukim elementom sa pokazivacem zagusenja vazduha.
